Dark energy with non-adiabatic sound speed: initial conditions and detectability  

SciTech Connect

Assuming that the universe contains a dark energy fluid with a constant linear equation of state and a constant sound speed, we study the prospects of detecting dark energy perturbations using CMB data from Planck, cross-correlated with galaxy distribution maps from a survey like LSST. We update previous estimates by carrying a full exploration of the mock data likelihood for key fiducial models. We find that it will only be possible to exclude values of the sound speed very close to zero, while Planck data alone is not powerful enough for achieving any detection, even with lensing extraction. We also discuss the issue of initial conditions for dark energy perturbations in the radiation and matter epochs, generalizing the usual adiabatic conditions to include the sound speed effect. However, for most purposes, the existence of attractor solutions renders the perturbation evolution nearly independent of these initial conditions.

Artificial neural networks for breathing and snoring episode detection in sleep sounds  

Science Journals Connector (OSTI)

Obstructive sleep apnea (OSA) is a serious disorder characterized by intermittent events of upper airway collapse during sleep. Snoring is the most common nocturnal symptom of OSA. Almost all OSA patients snore, but not all snorers have the disease. Recently, researchers have attempted to develop automated snore analysis technology for the purpose of OSA diagnosis. These technologies commonly require, as the first step, the automated identification of snore/breathing episodes (SBE) in sleep sound recordings. Snore intensity may occupy a wide dynamic range (>95 dB) spanning from the barely audible to loud sounds. Low-intensity SBE sounds are sometimes seen buried within the background noise floor, even in high-fidelity sound recordings made within a sleep laboratory. The complexity of SBE sounds makes it a challenging task to develop automated snore segmentation algorithms, especially in the presence of background noise. In this paper, we propose a fundamentally novel approach based on artificial neural network (ANN) technology to detect SBEs. Working on clinical data, we show that the proposed method can detect SBE at a sensitivity and specificity exceeding 0.892 and 0.874 respectively, even when the signal is completely buried in background noise (SNR

MiniDFT

MiniDFT MiniDFT MiniDFT Description MiniDFT is a plane-wave denstity functional theory (DFT) mini-app for modeling materials. Given an set of atomic coordinates and pseudopotentials, MiniDFT computes self-consistent solutions of the Kohn-Sham equations using either the LDA or PBE exchange-correlation functionals. For each iteration of the self-consistent field cycle, the Fock matrix is constructed and then diagonalized. To build the Fock matrix, Fast Fourier Transforms are used to tranform orbitals from the plane wave basis ( where the kinetic energy is most readily compted ) to real space (where the potential is evaluated ) and back. Davidson diagonalization is used to compute the orbital energies and update the orbital coefficients. The MiniDFT mini-app was excised from the general-purpose Quantum Espresso

Chapter 25 - Intentional Islanding of Distribution Network Operation with Mini Hydrogeneration  

Science Journals Connector (OSTI)

Abstract The abundant presence of large river basins made Brazil a worldwide powerhouse of hydroelectricity. To maintain its long-tradition of clean energy producer, Brazil also is investing in mini hydro plants, of few megawatts, able to supply small towns in rural areas. This chapter focuses on a real case study of a mini hydro power plant connected to a rural distribution feeder. The investigations presented in this chapter highlight important stages for a successful intentional islanding operation. Those are the detection of the islanding, the necessary change in the control modes of voltage and frequency regulation, the islanding formation with load/generation balancing, the islanding autonomous operation and the reconnection to the main grid. Although, not yet established as a common practice in Brazil, islanding operation of renewable DG can improve reliability indices and help the human effort in diminishing global warming, if technically sound solutions are applied.

Implosion sound  

Science Journals Connector (OSTI)

An open end axisymmetrical cavity is used to study the generation of implosion sound. The cross section of the cavity’s profile has a shape which will distort the wave front of a plane shock wave converging it into a single point. Hence a spherical collapsing phenomenon can be approximately achieved when a shock wave propagates into the opening of this finite size artificial cavity. Through the shock and shock interference mechanism a strong impulse therefore is generated at the focal point caused by the pressure difference between the inside and outside of the cavity. This highly localized impulse then is radiated out from the opening of the cavity as a sound projector. A prototype model of 0.5 l size has been constructed and tested in the laboratory. The preliminary experimental results indicated that this device can reach a peak sound pressure level of 146 dB//20 ?Pa in air and 185 dB//30 ?Pa in water with an ambient pressure of 1 atmosphere (1 bar). The 50% pulse width is about 20 and 30 ?s for air and water respectively. Analysis and application of this type of sound projector will be discussed.

SciTech Connect

The MiniCAM, short for the Mini-Climate Assessment Model, is an integrated assessment model of moderate complexity focused on energy and agriculture sectors. The model produces emissions of greenhouse gases (carbon dioxide, methane and nitrous oxide) and other radiatively important substances such as sulfur dioxide. Through incorporation of the simple climate model MAGICC, the consequences of these emissions for climate change and sea-level rise can be examined. The MiniCAM is designed to be fast and flexible.

Sound | Open Energy Information

Sound Sound Jump to: navigation, search Improved engineering and appropriate use of setbacks near residents has largely eliminated the problem wind farms had with noise in the 1980s and 1990s. Aerodynamic noise has been reduced by advancing blade design and orienting blades upwind of the turbine tower. A small amount of noise is generated by the mechanical components of the turbine. Modern wind turbines are designed with noise reduction in mind. Sound power levels at the source of a wind turbine are in the range of 90-105 dB(A). Proper setback requirements reduce wind farm sound pressure to background-noise levels. For example, at a distance of 350 meters, the sound pressure level for a wind farm is typically less than 45 dB(A). Rural background sound pressure is typically around 30-45dB(A). Higher wind

An ion trap is described which operates in the regime between research ion traps which can detect ions with a mass resolution of better than 1:10{sup 9} and commercial mass spectrometers requiring 10{sup 4} ions with resolutions of a few hundred. The power consumption is kept to a minimum by the use of permanent magnets and a novel electron gun design. By Fourier analyzing the ion cyclotron resonance signals induced in the trap electrodes, a complete mass spectra in a single combined structure can be detected. An attribute of the ion trap mass spectrometer is that overall system size is drastically reduced due to combining a unique electron source and mass analyzer/detector in a single device. This enables portable low power mass spectrometers for the detection of environmental pollutants or illicit substances, as well as sensors for on board diagnostics to monitor engine performance or for active feedback in any process involving exhausting waste products. 10 figs.

Electrochemiluminescent microoptoprobe with mini-grid working electrode and self-contained sample container  

Science Journals Connector (OSTI)

A new electrochemiluminescence (ECL) microoptoprobe with simple structure, small sampling volume and high efficiency was developed. It was constructed by fixing the transparent gold mini-grid on the end surface of the optical fiber, and by surrounding the fiber with the counter- and reference electrodes to form a self-contained three-electrode system. The use of mini-grid electrode increased the surface area and collection efficiency, which resulted in higher ECL signal and better sensitivity. The counter electrode together with one end of the fiber formed a mini-vessel, which eliminated the need of additional container and allowed to perform ECL detection in a very small volume (about 10 ?l). The microoptoprobe obtained was characterized with the Ru(bpy)32+–tripropylamine system and was applied for the determination of oxalate and chlorpromazine (CPZ). Detection limits (S/N=3) were 5×10?7 and 1×10?6 mol l?1 for oxalate and CPZ, respectively. The linear range for oxalate and CPZ extended from 1×10?6 to 1×10?3 mol l?1, and from 5×10?6 to 5×10?4 mol l?1, respectively.

Mini-Optics Solar Energy Concentrator  

E-Print Network (OSTI)

This invention deals with the broad general concept for focussing light. A mini-optics tracking and focussing system is presented for solar power conversion that ranges from an individual's portable system to solar conversion of electrical power that can be used in large scale power plants for environmentally clean energy. It can be rolled up, transported, and attached to existing man-made, or natural structures. It allows the solar energy conversion system to be low in capital cost and inexpensive to install as it can be attached to existing structures since it does not require the construction of a superstructure of its own. This novel system is uniquely distinct and different from other solar tracking and focussing processes allowing it to be more economical and practical. Furthermore, in its capacity as a power producer, it can be utilized with far greater safety, simplicity, economy, and efficiency in the conversion of solar energy.

Mini-chamber, an advanced protection concept for NIF  

SciTech Connect

Inertial confinement fusion (ICF) target debris and ablated near-target materials pose the primary threat to the National Ignition Facility (NIF) final optics debris shields, as well as a major challenge in future inertial fusion energy (IFE) power plants. This work discusses a NIF `mini-chamber,` designed to mitigate the debris threat. Although the NIF base-line design protects against debris using a frost-protected target positioner and refractory first-wall coatings, the mini-chamber provides important flexibility in three areas: debris-shield protection from beyond-design basis shots (i.e. heavy hohlraums, special diagnostics, shields); fielding of large experiments with significant surface ablation; and studying key ablation and gas-dynamics issues for liquid-wall IFE power plants. Key mini-chamber modeling results are presented, followed by discussion of equipment requirements for fielding a NIF mini-chamber. 7 refs., 3 figs.

Mini-Split Heat Pumps Multifamily Retrofit Feasibility Study  

SciTech Connect

Mini-split heat pumps can provide space heating and cooling in many climates and are relatively affordable. These and other features make them potentially suitable for retrofitting into multifamily buildings in cold climates to replace electric resistance heating or other outmoded heating systems. This report investigates the suitability of mini-split heat pumps for multifamily retrofits. Various technical and regulatory barriers are discussed and modeling was performed to compare long-term costs of substituting mini-splits for a variety of other heating and cooling options. A number of utility programs have retrofit mini-splits in both single family and multifamily residences. Two such multifamily programs are discussed in detail.

Zero lattice sound  

SciTech Connect

We study the N{sub f}-flavor Gross-Neveu model in 2+1 dimensions with a baryon chemical potential {mu}, using both analytical and numerical methods. In particular, we study the self-consistent Boltzmann equation in the Fermi liquid framework using the quasiparticle interaction calculated to O(1/N{sub f}), and find solutions for zero sound propagation for almost all {mu}>{mu}{sub c}, the critical chemical potential for chiral symmetry restoration. Next we present results of a numerical lattice simulation, examining temporal correlation functions of mesons defined using a point-split interpolating operator, and finding evidence for phononlike behavior characterized by a linear dispersion relation in the long wavelength limit. We argue that our results provide the first evidence for a collective excitation in a lattice simulation.

MiniBooNE liner integrity study  

SciTech Connect

The civil construction for the MiniBooNE project includes a 50-m decay path and beam absorbers. The decay path is a six-foot diameter corrugated metal pipe (CMP). To prevent activation of the groundwater, the CMP and beam absorbers are surrounded by crushed aggregate, and enclosed in a double-walled geotextile membrane, referred to as the liner. The minimum distance from the beam centerline to the liner is 10 feet. The double-wall construction of the liner forms three regions, the containment volume, the interstitial volume, and the exterior. Each of these volumes is connected to monitoring wells at both the upstream and downstream ends of the decay volume, i.e. a total of six monitoring pipes extend to the surface. To confirm the integrity of the liner system following its placement, the firm Earth Tech was contracted to perform tests. Michael Williams was the primary contact with Earth Tech. The following is the report from Earth Tech, with minor changes in the interest of clarity. A sketch of the decay region is shown; only one of the layers of the liner is shown, and only one monitoring port. At the time of these tests, the excavation in general, but particularly in the vicinity of the monitoring wells had not been backfilled in the final grade, as indicated by the dashed lines.

Sound emission from the gas of molecular superrotors  

E-Print Network (OSTI)

We use an optical centrifuge to deposit a controllable amount of rotational energy into dense molecular ensembles. Subsequent rotation-translation energy transfer, mediated by thermal collisions, results in the localized heating of the gas and generates strong sound wave, clearly audible to the unaided ear. For the first time, the amplitude of the sound signal is analyzed as a function of the experimentally measured rotational energy. The proportionality between the two experimental observables confirms that rotational excitation is the main source of the detected sound wave. As virtually all molecules, including the main constituents of the atmosphere, are amenable to laser spinning by the centrifuge, we anticipate this work to stimulate further development in the area of photo-acoustic control and spectroscopy.

HEARING AND LATERAL LINE | Effects of Human-Generated Sound on Fish  

Science Journals Connector (OSTI)

Abstract Fish depend on sound to communicate with one another, detect prey and predators, navigate from one place to another, avoid hazards, and analyze the world around them. The generation of noise in the ocean, lakes, and rivers by shipping, construction activities, seismic surveys, and sonar systems may affect fish adversely. In recent years, there has been a significant increase in the levels and incidence of human-generated underwater sound, and much of the technology contributing to ocean noise is new. Efforts are now underway to regulate activities that generate underwater sound with the aim of reducing noise levels and minimizing effects upon fish and other aquatic animals.

Detection threshold  

Science Journals Connector (OSTI)

Detection threshold or recognition differential is defined as the signal?to?noise ratio at the beamformer output required for detection. An introduction to this topic is provided in Uricks’ Principles of Underwater Sound. The subject is frequently a source of confusion due to the multiple possible definitions of signal?to?noise ratio the effects of nonlinearities in the signal processing and the overall complexity of the sonar operators job of signal recognition in real?world clutter. In this paper a review of the basic theory of mathematical relationships are provided followed by a discussion of practical limitations in applying simple formulas to performance predictions. The relationships of detection threshold to the signal?processing approach and background?noise statistics are discussed. Active sonars in both noise and reverberation as well as passive sonars involving energy detection spectral analysis and cross correlators are discussed.

Processing of prosthetic heart valve sounds for single leg separation classification  

SciTech Connect

Efforts are concentrated on the sounds corresponding to the heart valve opening cycle. Valve opening and closing acoustics present additional information about the outlet strut condition---the structural component implicated in valve failure. The importance of the opening sound for single leg separation detection/classification is based on the fact that as the valve opens, the disk passively hits the outlet strut. The opening sounds thus yield direct information about outlet strut condition with minimal amount of disturbance caused by the energy radiated from the disk. Hence the opening sound is a very desirable acoustic signal to extract. Unfortunately, the opening sounds have much lower signal levels relative to the closing sounds and therefore noise plays a more significant role than during the closing event. Because of this it is necessary to screen the sounds for outliers in order to insure a high sensitivity of classification. Because of the sharp resonances appearing in the corresponding spectrum, a parametric processing approach is developed based on an autoregressive model which was selected to characterize the sounds emitted by the Bjork--Shiley convexo--concave (BSCC) valve during opening cycle. First the basic signals and the extraction process used to create an ensemble of heart valve sounds are briefly discussed. Next, a {ital beat} {ital monitor} capable of rejecting beats that fail to meet an acceptance criteria based on their spectral content is developed. Various approaches that have been utilized to enhance the screened data and produce a reliable {ital heart} {ital valve} {ital spectrogram} which displays the individual sounds (power) as a function of beat number and temporal frequency are discussed. Once estimated, the spectrogram and associated parameters are used to develop features supplied to the various classification schemes. Finally, future work aimed at even further signal enhancement and improved classifier performance is discussed.

Research on Induction Motor for Mini Electric Vehicles  

Science Journals Connector (OSTI)

The motor of a mini electric vehicle uses dozens of storage batteries as power supply, which has low voltage and large current. Therefore, the loss and temperature raise of the motor is high. In this paper, the loss of different induction motors for mini electric vehicles is calculated and the effects of rotor materials and air gap length on the performance of these motors are studied. The analyses show that the efficiency of the motor with a copper mouse cage rotor is considerably higher than that of the motor with a aluminum rotor. The temperature raise of both an air-cooling and a water-cooling induction motor is analyzed, which demonstrates that the temperature raise of the motor windings is higher than that of the other parts, and the temperature raise of the water-cooling motor is lower than that of the air-cooling motor. To verify the results of the theoretical analyses, four prototype induction motors (aluminum rotor, copper mouse cage rotor, air-cooling and spiral groove machine) have been designed and processed. The experiments to measure the efficiency and temperature raise were carried out on these motors. The experimental results prove that the theoretical analyses are correct.

Cooling down MiniGRAIL to milli-Kelvin temperatures  

Science Journals Connector (OSTI)

The latest developments in the construction of the ultra-cryogenic spherical detector MiniGRAIL are presented. The room temperature part of the vibration isolation system was improved and provided with an attenuation of about 60 dB around 3 kHz. The transfer function of the cryogenic stages gave about 20 dB per stage, at the resonant frequency of the sphere. The latest results of three cryogenic tests at ultra-low temperature of the spherical detector MiniGRAIL, using several thermal anchorings, are presented. Minimum temperatures of 20 mK on the mixing chamber of the dilution refrigerator and 79 mK on the surface of the sphere were reached. During the last cool down, two capacitive transducers were mounted on the sphere. The first was coupled to a room temperature FET amplifier and the second to a transformer and a double stage SQUID amplifier. Unfortunately the SQUID did not work, so only the first resonator could be used. An equivalent temperature of about 20 K was measured during an acquisition run of 7 h, using the first transducer corresponding to the FET white noise.

Covariance of dark energy parameters and sound speed constraints from large HI surveys  

E-Print Network (OSTI)

An interesting probe of the nature of dark energy is the measure of its sound speed, $c_s$. We review the significance for constraining sound speed models of dark energy using large neutral hydrogen (HI) surveys with the Square Kilometre Array (SKA). Our analysis considers the effect on the sound speed measurement that arises from the covariance of $c_s$ with the dark energy density, $\\Omega_\\LLambda$, and a time-varying equation of state, $w(a)=w_0+(1-a)w_a$. We find that the approximate degeneracy between dark energy parameters that arises in power spectrum observations is lifted through redshift tomography of the HI-galaxy angular power spectrum, resulting in sound speed constraints that are not severely degraded. The cross-correlation of the galaxy and the integrated Sachs-Wolfe (ISW) effect spectra contributes approximately 10 percent of the information that is needed to distinguish variations in the dark energy parameters, and most of the discriminating signal comes from the galaxy auto-correlation spectrum. We also find that the sound speed constraints are weakly sensitive to the HI bias model. These constraints do not improve substantially for a significantly deeper HI survey since most of the clustering sensitivity to sound speed variations arises from $z \\lsim 1.5$. A detection of models with sound speeds close to zero, $c_s \\lsim 0.01,$ is possible for dark energy models with $w\\gsim -0.9$.

Measurement of sound transmission through mud at Dodge Pond, Connecticut.  

Science Journals Connector (OSTI)

Questions important to the sonic detection of buried ordinance are whether the sound dispersion and attenuation of muddy bottoms can be predicted and verified. Wood and Weston [Acustica (1964)] measured compressional speeds in harbor mud 3% less than that of water with attenuation considerably less than those of sandy/silty sediments. A recent theoretical treatment [Pierce and Carey POMA 7001 (2009)] making use of the Mallock–Wood equation and of a card?house theory of the structure of mud estimates the slow sound speed to depend on porosity as 1?(0.35)(1??). Present measurements at frequencies between 1 and 10 kHz with a buried array in the depositional mud at the bottom of Dodge Pond which contains considerable gas microbubbles yield speeds of the order of 60% of the sound speed in water. The initial measurements on the disturbed sediment were found to be strongly influenced by scattering from larger bubbles whereas the results after a period of 10 months showed the effect of a smaller size distribution of bubbles. Estimates based on the Dodge Pondmeasurements and on the card?house theory of the propagation characteristics and of the effect of micro?bubbles are discussed. [Sponsored by SERDP?NSWC?PCD.

Study on Performance and Internal Flow Condition of Mini Turbo?Pump  

Science Journals Connector (OSTI)

Mini turbo?pumps which have a diameter smaller than 100mm are utilized in many fields; automobile radiator pump artificial heart pump cooling pump for electric devices washing machine pump and so on. And the needs for the mini turbo?pumps would become larger with the increase of the application of it for electrical machines. It is desirable that the mini turbo?pump design is as simple as possible due to the limitation of the precision for manufacture. But the design method for the mini turbo?pump is not established because the internal flow condition for these small?sized fluid machineries is not clarified and conventional theory is not conductive for small?sized pumps because of the low Reynolds number and the size effects. Therefore we started the research of the mini turbo?pump for the purpose of development of high performance mini turbo?pump with simple structure. As a first step of this research mini turbo?pump with the 46mm rotor diameter was designed based on the conventional design method in order to clarify the problems for the application of conventional method for mini turbo?pump in details. The three dimensional steady numerical flow analysis was conducted with the commercial code (Fluent6.3). The numerical flow analysis was also performed under the condition with and without a tip clearance because the tip clearance influence on the performance and internal flow condition is extremely large for mini turbo?pumps. It was clarified from the numerical results that head of the mini turbo?pump at the designed point without the tip clearance satisfied the designed value head H?=?1.2 m and the efficiency is about ??=?60% which is acceptable value for the centrifugal pump. On the other hand head and efficiency decreased drastically with the increase of the tip clearance. The flow condition near the tip region was influenced by the leakage flow from the blade tip. And it is observed by the results of the total pressure distributions that the total pressure loss near the tip is considerably large. In the present paper the performance of the mini turbo?pump is shown and the internal flow condition is clarified with the results of the numerical flow analysis. Furthermore the effects of the tip clearance on the performance are investigated and high performance rotor design for mini turbo?pump would be considered.

Ultrasonic Sound Field Mapping Through Coarse Grained Cast Austenitic Stainless Steel Components  

SciTech Connect

The Pacific Northwest National Laboratory (PNNL) has been involved with nondestructive examination (NDE) of coarse-grained cast austenitic stainless steel (CASS) components for over 30 years. More recent work has focused on mapping the ultrasonic sound fields generated by low-frequency phased array probes that are typically used for the evaluation of CASS materials for flaw detection and characterization. The casting process results in the formation of large grained material microstructures that are nonhomogeneous and anisotropic. The propagation of ultrasonic energy for examination of these materials results in scattering, partitioning and redirection of these sound fields. The work reported here provides an assessment of sound field formation in these materials and provides recommendations on ultrasonic inspection parameters for flaw detection in CASS components.

Replacing Resistance Heating with Mini-Split Heat Pumps, Sharon, Connecticut (Fact Sheet)  

SciTech Connect

Mini-split heat pumps can provide space heating and cooling in many climates and are relatively affordable. These and other features make them potentially suitable for retrofitting into multifamily buildings in cold climates to replace electric resistance heating or other outmoded heating systems. This report investigates the suitability of mini-split heat pumps for multifamily retrofits. Various technical and regulatory barriers are discussed and modeling was performed to compare long-term costs of substituting mini-splits for a variety of other heating and cooling options. A number of utility programs have retrofit mini-splits in both single family and multifamily residences. Two such multifamily programs are discussed in detail.

Anthropogenic sounds ? Potential effects on fish  

Science Journals Connector (OSTI)

There is concern that human?generated sounds may have deleterious effects on fish. This paper will review some of what is currently known about these effects and consider the questions that have to be answered before developing models to enable "prediction" of sound effects on particular fish species. A major restriction is that there are few peer?reviewed data on effects of anthropogenic sources on fish. Extrapolation from these results is further confounded since experiments differ in many ways each of which may alter the resultant impact on fish. For example studies vary in sounds types tested (e.g. pile driving vs. ship noise) signal parameters (intensity number of repetitions) species used fish age etc. Moreover a singularly important issue is that while many of the issues and impact mechanisms are potentially amenable to experimental lab study the ultimate questions regarding the effects of sound on fish behavior need to field based and require long?term observations where behaviour of wild fish is not constrained. Only by observing fish in the wild will we ultimately understand if and how anthropogenic sounds impact fish both during exposure and more importantly for extended periods after the termination of the sound.

Study of the Acoustic Effects of Hydrokinetic Tidal Turbines in Admiralty Inlet, Puget Sound  

SciTech Connect

Hydrokinetic turbines will be a source of noise in the marine environment - both during operation and during installation/removal. High intensity sound can cause injury or behavioral changes in marine mammals and may also affect fish and invertebrates. These noise effects are, however, highly dependent on the individual marine animals; the intensity, frequency, and duration of the sound; and context in which the sound is received. In other words, production of sound is a necessary, but not sufficient, condition for an environmental impact. At a workshop on the environmental effects of tidal energy development, experts identified sound produced by turbines as an area of potentially significant impact, but also high uncertainty. The overall objectives of this project are to improve our understanding of the potential acoustic effects of tidal turbines by: (1) Characterizing sources of existing underwater noise; (2) Assessing the effectiveness of monitoring technologies to characterize underwater noise and marine mammal responsiveness to noise; (3) Evaluating the sound profile of an operating tidal turbine; and (4) Studying the effect of turbine sound on surrogate species in a laboratory environment. This study focuses on a specific case study for tidal energy development in Admiralty Inlet, Puget Sound, Washington (USA), but the methodologies and results are applicable to other turbine technologies and geographic locations. The project succeeded in achieving the above objectives and, in doing so, substantially contributed to the body of knowledge around the acoustic effects of tidal energy development in several ways: (1) Through collection of data from Admiralty Inlet, established the sources of sound generated by strong currents (mobilizations of sediment and gravel) and determined that low-frequency sound recorded during periods of strong currents is non-propagating pseudo-sound. This helped to advance the debate within the marine and hydrokinetics acoustic community as to whether strong currents produce propagating sound. (2) Analyzed data collected from a tidal turbine operating at the European Marine Energy Center to develop a profile of turbine sound and developed a framework to evaluate the acoustic effects of deploying similar devices in other locations. This framework has been applied to Public Utility District No. 1 of Snohomish Country's demonstration project in Admiralty Inlet to inform postinstallation acoustic and marine mammal monitoring plans. (3) Demonstrated passive acoustic techniques to characterize the ambient noise environment at tidal energy sites (fixed, long-term observations recommended) and characterize the sound from anthropogenic sources (drifting, short-term observations recommended). (4) Demonstrated the utility and limitations of instrumentation, including bottom mounted instrumentation packages, infrared cameras, and vessel monitoring systems. In doing so, also demonstrated how this type of comprehensive information is needed to interpret observations from each instrument (e.g., hydrophone data can be combined with vessel tracking data to evaluate the contribution of vessel sound to ambient noise). (5) Conducted a study that suggests harbor porpoise in Admiralty Inlet may be habituated to high levels of ambient noise due to omnipresent vessel traffic. The inability to detect behavioral changes associated with a high intensity source of opportunity (passenger ferry) has informed the approach for post-installation marine mammal monitoring. (6) Conducted laboratory exposure experiments of juvenile Chinook salmon and showed that exposure to a worse than worst case acoustic dose of turbine sound does not result in changes to hearing thresholds or biologically significant tissue damage. Collectively, this means that Chinook salmon may be at a relatively low risk of injury from sound produced by tidal turbines located in or near their migration path. In achieving these accomplishments, the project has significantly advanced the District's goals of developing a demonstration-scale tidal energy proj

Sound Speed Perturbations Due to Internal Tides  

Science Journals Connector (OSTI)

Internal tides are perhaps the most prevalent and largest amplitude internal gravity waves in the ocean. They are commonly generated by the scattering of surfacetidal energy into internal modes when the surfacetides propagate on to continental shelves. A portion of the internal tidal energy propagates into the deep ocean. One of the effects of internal tides on underwater acoustic propagation is to perturb the temperature and salinity versus depth profiles and thus the sound speed versus depth profile. Starting with temperature and salinity versus depth profiles from near Eleuthera Island the internal tide eigenfunctions as well as the sound speed profile have been computed for a water depth of 4500 m. Assuming a value for the vertical displacement amplitude of a first vertical mode internal tide the perturbed temperature and salinity profiles have been computed. From these perturbed profiles the consequent perturbed sound speed profiles have been computed for cases of maximum up and down internal tide displacement. The first mode internal tide has no vertical displacement at the sea surface and bottom and a maximum near the base of the main thermocline (depth of about 1200 m). Since the SOFAR axis is also near the base of the main thermocline and since the pressureeffects on sound speed are predominant below the SOFAR axis the sound speed perturbation due to the first mode internal tide is greatest at a depth (about 550 m) above the SOFAR axis. An internal tide with a maximum vertical displacement of 10 m produces a maximum sound speed perturbation of ±0.7 m/sec.

Neutrino-nucleus neutral current elastic interactions measurement in MiniBooNE  

SciTech Connect

The MiniBooNE experiment at the Fermi National Accelerator Laboratory (Fermilab) was designed to search for {nu}{sub {mu}} {yields} {nu}{sub e} neutrino oscillations at {Delta}m{sup 2} {approx} 1 eV{sup 2} using an intense neutrino flux with an average energy E{sub {nu}} {approx} 700 MeV. From 2002 to 2009 MiniBooNE has accumulated more than 1.0 x 10{sup 21} protons on target (POT) in both neutrino and antineutrino modes. MiniBooNE provides a perfect platform for detailed measurements of exclusive and semiinclusive neutrino cross-sections, for which MiniBooNE has the largest samples of events up to date, such as neutral current elastic (NCE), neutral current {pi}{sup 0}, charged current quasi-elastic (CCQE), charged current {pi}{sup +}, and other channels. These measured cross-sections, in turn, allow to improve the knowledge of nucleon structure. This thesis is devoted to the study of NCE interactions. Neutrino-nucleus neutral current elastic scattering ({nu}N {yields} {nu}N) accounts for about 18% of all neutrino interactions in MiniBooNE. Using a high-statistics, high purity sample of NCE interactions in MiniBooNE, the flux-averaged NCE differential cross-section has been measured and is being reported here. Further study of the NCE cross-section allowed for probing the structure of nuclei. The main interest in the NCE cross-section is that it may be sensitive to the strange quark contribution to the nucleon spin, {Delta}s, this however requires a separation of NCE proton ({nu}p {yields} {nu}p) from NCE neutron ({nu}n {yields} {nu}n) events, which in general is a challenging task. MiniBooNE uses a Cherenkov detector, which imposes restrictions on the measured nucleon kinematic variables, mainly due to the impossibility to reconstruct the nucleon direction below the Cherenkov threshold. However, at kinetic energies above this threshold MiniBooNE is able to identify NCE proton events that do not experience final state interactions (FSI). These events were used for the {Delta}s measurement. In this thesis MiniBooNE reports the NCE (n+p) cross-section, the measurement of the axial mass, M{sub A}, and the {Delta}s parameter from the NCE data.

'Mini'-Roadmapping - Ensuring Timely Sites' Cleanup/Closure by Resolving Science & Technology Issues  

SciTech Connect

Roadmapping is a powerful tool to manage technical risks and opportunities associated with complex problems. Roadmapping identifies technical capabilities required for both project- and program-level efforts and provides the basis for plans that ensure the necessary enabling activities will be done when needed. Roadmapping reveals where to focus further development of the path forward by evaluating uncertainties for levels of complexity, impacts, and/or the potential for large payback. Roadmaps can be customized to the application, a ''graded approach'' if you will. Some roadmaps are less detailed. We have called these less detailed, top-level roadmaps ''mini-roadmaps''. These mini roadmaps are created to tie the needed enablers (e.g., technologies, decisions, etc.) to the functions. If it is found during the mini-roadmapping that areas of significant risk exist, then those can be roadmapped further to a lower level of detail. Otherwise, the mini-roadmap may be sufficient to manage the project/program risk. Applying a graded approach to the roadmapping can help keep the costs down. Experience has indicated that it is best to do mini-roadmapping first and then evaluate the risky areas to determine whether to further evaluate those areas. Roadmapping can be especially useful for programs/projects that have participants from multiple sites, programs, or other entities which are involved. Increased synergy, better communications, and increased cooperation are the results from roadmapping a program/project with these conditions.

Chemical Concentrations in Field Mice from Open-Detonation Firing Sites TA-36 Minie and TA-39 Point 6 at Los Alamos National Laboratory  

SciTech Connect

Field mice (mostly Peromyscus spp.) were collected at two open-detonation (high explosive) firing sites - Minie at Technical Area (TA) 36 and Point 6 at TA-39 - at Los Alamos National Laboratory in August of 2010 and in February of 2011 for chemical analysis. Samples of whole body field mice from both sites were analyzed for target analyte list elements (mostly metals), dioxin/furans, polychlorinated biphenyl congeners, high explosives, and perchlorate. In addition, uranium isotopes were analyzed in a composite sample collected from TA-36 Minie. In general, all constituents, with the exception of lead at TA-39 Point 6, in whole body field mice samples collected from these two open-detonation firing sites were either not detected or they were detected below regional statistical reference levels (99% confidence level), biota dose screening levels, and/or soil ecological chemical screening levels. The amount of lead in field mice tissue collected from TA-39 Point 6 was higher than regional background, and some lead levels in the soil were higher than the ecological screening level for the field mouse; however, these levels are not expected to affect the viability of the populations over the site as a whole.

Underwater and in-air sounds from a small hovercraft  

Science Journals Connector (OSTI)

Underwater and in-air recordings were made from a boat anchored near Prudhoe Bay Alaska while a Griffon 2000TD hovercraft drove by at or near full power on four passes. At the closest point of approach (CPA 6.5 m ) underwater broadband ( 10 – 10 000 Hz ) levels reached 133 and 131 dB re : 1 ? Pa at depths of 1 and 7 m respectively. In-air unweighted and A-weighted broadband ( 10 – 10 000 Hz ) levels reached 104 and 97 dB re : 20 ? Pa respectively. The hovercraft produced sound at a wide range of frequencies. Both underwater and in air the largest spectral peak was near 87 Hz which corresponded to the blade rate of the thrust propeller. In addition the spectral composition included several harmonics of this frequency. The shaft or blade rate of the lift fan was barely detectable underwater despite its proximity to the water. The hovercraft was considerably quieter underwater than similar-sized conventional vessels and may be an attractive alternative when there is concern over underwater sounds.

Assessment of HVAC sound power data for sensitive spaces.  

Science Journals Connector (OSTI)

Certification testing of air handling unit sound power (PWL) indicates that individual unit PWL can vary significantly from manufacturer published data. Published data are typically based on a limited number of actual tests with results extrapolated for other fan sizes and operating conditions. Although published data are normally acceptable for routine applications indiscriminate use for sensitive designs (studios theaters conference centers etc.) can result in excessive finished space noise levels. The fact that the design goals have been exceeded can be accurately documented. The exact reason for the exceedance however cannot be as firmly established in a complex system. Certification PWL testing of air handling units prior to installation can detect PWL variations from the published data. Individual unit PWL certification was often not cost effective prior to the developement of sound intensity and the establishment and use of recognized standards for in situ PWL testing (e.g. ASA 104?1992 ANSI S.12.12.1992). Case histories to be presented document fan PWL variations from published data of up to 10 dB and higher in certain octave bands.

Determination of sound power of coupled machines  

Science Journals Connector (OSTI)

Several procedures are available for the determination of the sound power level of machines in normal environments. Most of these give adequate results for single medium?sized equipment but difficulties arise in extending the concepts to large coupled machines. [“Evaluation of Proposed ASME PTC 36 Code for Sound Power Level Determination of Large Steam Turbine Generators ” S.E. Grabkowski J. MacDonald and T. Van Schaick (General Electric Company) to be presented at Fall 1975 ASME meeting.] Much of the problem is because the direct acoustic field of a component machine may not extend to as much as one foot from its surface due to reverberation from other components. A procedure is suggested in which all acoustic measurements are confined to surfaces near each component machine. Correction is made for the reverberant acoustic field of the entire environment. The correction procedure utilizes reverberation time determinations from impulsive noise tests; and applies a Monte Carlo approach to the problem of correcting for nearfield effects in the evaluation of sound power. An iterative computation is employed. Comparisons with free?field sound power determinations are shown.

Sound radiation measurement with nearfield holography  

Science Journals Connector (OSTI)

With holography an entire 3D wave field can be reconstructed from data obtained on a single 2D surface. Such high information content has made holography a powerful research tool and useful extensions from its original optical domain to other wave fields such as sound have naturally been pursued. However it has usually been assumed that the resolution of a holographicreconstruction is limited by the wavelength of the radiation; this limitation severely diminishes the usefulness of holography for sound fields when the wavelengths are many times larger than the objects to be imaged. We have developed a new technique called nearfield holography which eliminates the wavelength resolution limit and in addition permits a determination of: (1) the complete sound pressure and particle velocity fields produced by the source; (2) the mode of vibration of the surfaces of the source; (3) the vector intensity field (showing flow of acoustic energy) around the source; (4) the farfield directivity pattern; (5) the total power radiated into a half?space. A particularly interesting application of nearfield holography occurs in the study of sound radiation from musical instruments. [Work supported by ONR.

Passive acoustic monitoring of biological and anthropogenic sounds at America’s first offshore wind farm  

Science Journals Connector (OSTI)

Cape Wind situated in Nantucket Sound Massachusetts is poised to become America’s first offshore windfarm. Our objective is to establish baseline (pre-construction) sound levels of human and biological activity including diel and seasonal variability of various sound types at the construction site and three nearby comparison sites. Acoustic recorders have been deployed since April 2012 recording on a 10% duty cycle (sample rate: 80 kHz). Biological contributions to the local soundscape are primarily fish sounds with the dominant signal likely being cusk eel (Family Ophidiidae) calls. These calls which are composed of stereotyped pulses with an average bout duration of 3.3 ±0.8 s and mean peak frequency of 1030 ±200 Hz show both seasonal and diel variation. Dense choruses were detected during summer (July) but limited activity occurred in the fall and winter. During vocal periods detections occurred throughout the day but peaked near dusk. Vessel traffic also showed diel and seasonal trends with peaks during the daytime and in the summer which indicates that boat activity can be tracked acoustically. These trends in biological and anthropogenic activity provide key baseline records for evaluating the influence of windfarm construction and operation on a local US soundscape.

DISCOVERY OF THE TRANSITION OF A MINI-BROAD ABSORPTION LINE INTO A BROAD ABSORPTION LINE IN THE SDSS QUASAR J115122.14+020426.3  

SciTech Connect

We present the detection of a rare case of dramatic strengthening in the UV absorption profiles in the spectrum of the quasar J115122.14+020426.3 between observations {approx}2.86 yr apart in the quasar rest frame. A spectrum obtained in 2001 by the Sloan Digital Sky Survey shows a C IV ''mini-broad'' absorption line (FWHM = 1220 km s{sup -1}) with a maximum blueshift velocity of {approx}9520 km s{sup -1}, while a later spectrum from the Very Large Telescope shows a significantly broader and stronger absorption line, with a maximum blueshift velocity of {approx}12, 240 km s{sup -1} that qualifies as a broad absorption line. A similar variability pattern is observed in two additional systems at lower blueshifted velocities and in the Ly{alpha} and N V transitions as well. One of the absorption systems appears to be resolved and shows evidence for partial covering of the quasar continuum source (C{sub f} {approx} 0.65), indicating a transverse absorber size of, at least, {approx}6 Multiplication-Sign 10{sup 16} cm. In contrast, a cluster of narrower C IV lines appears to originate in gas that fully covers the continuum and broad emission line sources. There is no evidence for changes in the centroid velocity of the absorption troughs. This case suggests that at least some of the absorbers that produce ''mini-broad'' and broad absorption lines in quasar spectra do not belong to intrinsically separate classes. Here, the ''mini-broad'' absorption line is most likely interpreted as an intermediate phase before the appearance of a broad absorption line due to their similar velocities. While the current observations do not provide enough constraints to discern among the possible causes for this variability, future monitoring of multiple transitions at high resolution will help achieve this goal.

Sound?Power Production in Wind Instruments  

Science Journals Connector (OSTI)

This paper presents data for output sound powerP O of wind instruments relation to input power P I supplied by the player. P I was calculated as pV? where p equals mouth pressure and V? air flow rate through the instrument. P O was calculated from sound?pressure level and measurements of reverberation time in a live room of known volume. A part of the data was obtained in a room of unknown characteristics; from 15 comparable measurements on 8 different instruments in both the live and the unknown room data were obtained that allowed calculation of P O also from other experiments in the unknown room. Measurements were made on single notes played both pp and ff on each instrument; one low and one high note on the scale of each instrument were chosen. The ratio P O/P I representing the mechanical efficiency of wind instruments as sources of sound power varies from less than 0.001% to about 2%. It appears to increase with increasing P I and in some instruments with frequency. The consistent results obtained for 3 different flutes played by one performer suggest that the variability noted in the other data at least partially reflects individual differences in mechanical efficiency.

Sound insulation ratings—the STC revisited  

Science Journals Connector (OSTI)

About twenty years ago building authorities and their acoustical experts were faced with a confusing variety of schemes for rating the sound insulation of walls and floors. There was need for a definitive rating system that would digest the 16 transmission loss values that characterize a partition and produce a single number that would describe its sound insulation performance especially in respect to multi?family dwellings. Two standards committees ISO/TC 43 and ASTM E6 (now E33) began more or less together to develop a new improved rating system to fill this need. The product of these labors was what is known in North America as the ASTM sound transmission class (STC). This rating system was so successful that it was almost universally adopted—even in applications for which it was not intended. Despite the apparent success there is now increasing awareness of imperfections in the system. These are examined in light of accumulated data and experience to see whether the system could or should be improved by certain minor changes.

Future directions in impulsive sound sources  

Science Journals Connector (OSTI)

While impulsive acoustic sources have long been used by the geophysical community for underwater exploration sonar applications have been relatively uncommon. Recent work in the area of electric discharge devices has led to both a better understanding of the physics of this class of impulsive soundgenerator and to new devices which may in turn lead to an expanded role for such technology in sonar applications—in particular the observation that the electric arc commonly associated with sparker sound sources represents a wasteful and unnecessary complication. Proper electrode design and control of the electric discharge can eliminate the arc leaving only a steam bubble and can thereby enhance the low?frequency performance of such a device. Insight into the performance and potential of such devices is in part a result of improved computer modeling capabilities of the nonlinear processes associated with impulsive devices as well as on the use of high?speed data acquisition in interpreting experimental results. This is especially true for determining the effects of interactions in arrays of bubble sources. Beyond the electric discharge sources understanding of the coupling of energy from the bubble to the sound field suggests improvements for chemically driven sound sources as well. An update of work on these impulsive devices and the modeling efforts that support them is presented. The performance of some recently developed devices and the potential for future development will be discussed.

Electron source for a mini ion trap mass spectrometer  

DOE Patents (OSTI)

An ion trap is described which operates in the regime between research ion traps which can detect ions with a mass resolution of better than 1:10{sup 9} and commercial mass spectrometers requiring 10{sup 4} ions with resolutions of a few hundred. The power consumption is kept to a minimum by the use of permanent magnets and a novel electron gun design. By Fourier analyzing the ion cyclotron resonance signals induced in the trap electrodes, a complete mass spectra in a single combined structure can be detected. An attribute of the ion trap mass spectrometer is that overall system size is drastically reduced due to combining a unique electron source and mass analyzer/detector in a single device. This enables portable low power mass spectrometers for the detection of environmental pollutants or illicit substances, as well as sensors for on board diagnostics to monitor engine performance or for active feedback in any process involving exhausting waste products. 10 figs.

Evaluating the bonding condition of NASA spray on foam insulation (SOFI) using audio frequency sound absorption measurements  

Science Journals Connector (OSTI)

The bonding condition of the spray on foam insulation (SOFI) used to insulate the external tank of the NASA space shuttle can be found by using the audio frequency sound absorption coefficient. The ASTM E1050 standard method for sound absorptionmeasurements was used with an open?ended 1?in?diam cast acrylic impedance tube sealed to the SOFI with closed cell PVC foam. Two artificially disbonded locations measuring 1.0 in. by 5.5 in. by 0.0625 in. and 2.0 in. by 8.0 in. by 0.0625 in. were detected by peaks in the sound absorption coefficient spectrum. The peaks in the sound absorptionspectrum between 1000 and 4000 Hz were 25% to 50% higher over disbonded areas when compared to bonded locations. The maximum and minimum sound absorption levels for the foam ranged between approximately 0.1 and 0.3. The entire sample was scanned using the sound absorption peaks as indicators. Samples of 2?in.?thick polystyrene foam were used with different sized defects at different locations in the foam to relate defect size and location to peaks in absorption coeffi?cient spectrum.

Measurement of sound transmission through mud at Dodge Pond, Connecticut  

Science Journals Connector (OSTI)

Depositional muddy sediments are slow bottoms and pose a problem for the sonic detection of buried ordnance. This paper addresses the question: can the frequency dependent dispersion be predicted and verified by measurements in areas where buried object detection is required? Wood and Weston (Acustica V14 1964) have indicated that muddy sediments in the kHz range have a compressional speed 3% less than water with a frequency dependent attenuation (less than that of sand). A theoretical treatment of "muddy sediments" the Card House Theory (Pierce and Carey POMA (5) 7001 2009) estimates the slow sound speed and frequency dispersion proportional to mud porosity. Preliminary Dodge Pond results obtained with a buried array (1 to 10 kHz) are presented and illustrate the importance of micro-bubbles on the dispersion characteristic. The initial measurements on the disturbed sediment were found strongly influenced by scattering from larger bubbles whereas the results after a period of 10 months showed the effect of a smaller size distribution of bubbles. Estimates of the dispersion characteristic of mud and the effect of micro-bubbles are discussed. Finally the application of an impedance tube to the characterization of mud is discussed.

Searches for New Physics at MiniBooNE: Sterile Neutrinos and Mixing Freedom  

SciTech Connect

The MiniBooNE experiment was designed to perform a search for {nu}{sub {mu}} {yields} {nu}{sub e} oscillations in a region of {Delta}m{sup 2} and sin{sup 2} 2{theta} very different from that allowed by standard, three-neutrino oscillations, as determined by solar and atmospheric neutrino experiments. This search was motivated by the LSND experimental observation of an excess of {bar {nu}}{sub e} events in a {bar {nu}}{sub {mu}} beam which was found compatible with two-neutrino oscillations at {Delta}m{sup 2} {approx} 1 eV{sup 2} and sin{sup 2} 2{theta} < 1%. If confirmed, such oscillation signature could be attributed to the existence of a light, mostly-sterile neutrino, containing small admixtures of weak neutrino eigenstates. In addition to a search for {nu}{sub {mu}} {yields} {nu}{sub e} oscillations, MiniBooNE has also performed a search for {bar {nu}}{sub {mu}} {yields} {bar {nu}}{sub e} oscillations, which provides a test of the LSND two-neutrino oscillation interpretation that is independent of CP or CPT violation assumptions. This dissertation presents the MiniBooNE {nu}{sub {mu}} {yields} {nu}{sub e} and {bar {nu}}{sub {mu}} {yields} {bar {nu}}{sub e} analyses and results, with emphasis on the latter. While the neutrino search excludes the two-neutrino oscillation interpretation of LSND at 98% C.L., the antineutrino search shows an excess of events which is in agreement with the two-neutrino {bar {nu}}{sub {mu}} {yields} {bar {nu}}{sub e} oscillation interpretation of LSND, and excludes the no oscillations hypothesis at 96% C.L. Even though the neutrino and antineutrino oscillation results from MiniBooNE disagree under the single sterile neutrino oscillation hypothesis, a simple extension to the model to include additional sterile neutrino states and the possibility of CP violation allows for differences between neutrino and antineutrino oscillation signatures. In view of that, the viability of oscillation models with one or two sterile neutrinos is investigated in global fits to MiniBooNE and LSND data, with and without constraints from other oscillation experiments with similar sensitivities to those models. A general search for new physics scenarios which would lead to effective non-unitarity of the standard 3 x 3 neutrino mixing matrix, or mixing freedom, is also performed using neutrino and antineutrino data available from MiniBooNE.

Effective speed of sound in phononic crystals  

E-Print Network (OSTI)

A new formula for the effective quasistatic speed of sound $c$ in 2D and 3D periodic materials is reported. The approach uses a monodromy-matrix operator to enable direct integration in one of the coordinates and exponentially fast convergence in others. As a result, the solution for $c$ has a more closed form than previous formulas. It significantly improves the efficiency and accuracy of evaluating $c$ for high-contrast composites as demonstrated by a 2D example with extreme behavior.

Sound velocity bound and neutron stars  

E-Print Network (OSTI)

It has been conjectured that the velocity of sound in any medium is smaller than the velocity of light in vacuum divided by $\\sqrt{3}$. Simple arguments support this bound in non-relativistic and/or weakly coupled theories. The bound has been demonstrated in several classes of strongly coupled theories with gravity duals and is saturated only in conformal theories. We point out that the existence of neutron stars with masses around two solar masses combined with the knowledge of the equation of state of hadronic matter at "low" densities is in strong tension with this bound.

Sound Absorption in the Pacific Ocean

The absorption of sound in the Pacific Ocean at a nominal frequency of 75 kHz was measured over a horizontal path at depths of 910 and 3350 m. The results are 20.0±1.5 dB/km and 13.5±1.5 dB/km respectively which may be compared to values of 27.3 dB/km and 22.7 dB/km extrapolated from the empirical relation of Schulkin and Marsh. Evidently the useful range of this relation is severely limited. In addition the effect of pressure may be greater than previously suspected.

Pitch Perception of Complex Sounds: Nonlinearity Revisited  

E-Print Network (OSTI)

The ability of the auditory system to perceive the fundamental frequency of a sound even when this frequency is removed from the stimulus is an interesting phenomenon related to the pitch of complex sounds. This capability is known as ``residue'' or ``virtual pitch'' perception and was first reported last century in the pioneering work of Seebeck. It is residue perception that allows one to listen to music with small transistor radios, which in general have a very poor and sometimes negligible response to low frequencies. The first attempt, due to Helmholtz, to explain the residue as a nonlinear effect in the ear considered it to originate from difference combination tones. However, later experiments have shown that the residue does not coincide with a difference combination tone. These results and the fact that dichotically presented signals also elicit residue perception have led to nonlinear theories being gradually abandoned in favour of central processor models. In this paper we use recent results from the theory of nonlinear dynamical systems to show that physical frequencies produced by generic nonlinear oscillators acted upon by two independent periodic excitations can reproduce with great precision most of the experimental data about the residue without resorting to any kind of central processing mechanism.

Neutral Current pi0 Production in the MiniBooNE Antineutrino Data  

E-Print Network (OSTI)

The single largest background to future numubar to nuebar (numu to nue) oscillation searches is neutral current pi0 production. MiniBooNE, which began taking antineutrino data in January 2006, has the world's largest sample of pi0's produced by antineutrinos in the 1 GeV energy range. These neutral pions are primarily produced through the delta resonance but can also be created through "coherent production." The latter process is the coherent sum of glancing scatters of (anti)neutrinos off a neutron or proton, in which the nucleus is kept intact but a pi0 is created. Current analysis of NC pi0 production in the MiniBooNE antineutrino data will be discussed.

Current analysis of NC pi0 production in the MiniBooNE antineutrino data will be discussed.

Lineal energy calibration of mini tissue-equivalent gas-proportional counters (TEPC)  

SciTech Connect

Mini TEPCs are cylindrical gas proportional counters of 1 mm or less of sensitive volume diameter. The lineal energy calibration of these tiny counters can be performed with an external gamma-ray source. However, to do that, first a method to get a simple and precise spectral mark has to be found and then the keV/{mu}m value of this mark. A precise method (less than 1% of uncertainty) to identify this markis described here, and the lineal energy value of this mark has been measured for different simulated site sizes by using a {sup 137}Cs gamma source and a cylindrical TEPC equipped with a precision internal {sup 244}Cm alpha-particle source, and filled with propane-based tissue-equivalent gas mixture. Mini TEPCs can be calibrated in terms of lineal energy, by exposing them to {sup 137}Cesium sources, with an overall uncertainty of about 5%.

'Mini'-Roadmapping - Ensuring Timely Sites' Cleanup / Closure by Resolving Science and Technology Issues  

SciTech Connect

Roadmapping is a powerful tool to manage technical risks and opportunities associated with complex problems. Roadmapping identifies technical capabilities required for both project- and program-level efforts and provides the basis for plans that ensure the necessary enabling activities will be done when needed. Roadmapping reveals where to focus further development of the path forward by evaluating uncertainties for levels of complexity, impacts, and/or the potential for large payback. Roadmaps can be customized to the application, a “graded approach” if you will. Some roadmaps are less detailed. We have called these less detailed, top-level roadmaps “mini-roadmaps”. These miniroadmaps are created to tie the needed enablers (e.g., technologies, decisions, etc.) to the functions. If it is found during the mini-roadmapping that areas of significant risk exist, then those can be roadmapped further to a lower level of detail. Otherwise, the mini-roadmap may be sufficient to manage the project / program risk. Applying a graded approach to the roadmapping can help keep the costs down. Experience has indicated that it is best to do mini-roadmapping first and then evaluate the risky areas to determine whether to further evaluate those areas. Roadmapping can be especially useful for programs / projects that have participants from multiple sites, programs, or other entities which are involved. Increased synergy, better communications, and increased cooperation are the results from roadmapping a program / project with these conditions. And, as with any trip, the earlier you use a roadmap, the more confidence you will have that you will arrive at your destination with few, if any, problems. The longer the trip or complicated the route, the sooner the map is needed. This analogy holds true for using roadmapping for laying out program / project baselines and any alternative (contingency) plans. The mini-roadmapping process has been applied to past projects like the hydrogen gas generation roadmap and the subsurface contaminant focus area (SCFA), and it’s basic form is being applied in the formulation of the ‘2012 Plan’ at the Idaho National Engineering and Environmental Laboratory (INEEL). There are also plans to apply this process in the near future for other projects/programs.

Instrumentation for Studies of Sound in the Atmosphere  

Science Journals Connector (OSTI)

Explosive charges are fired on the earth's surface at points in Arizona California and San Clemente Island. The resulting sound waves centering at 2 cps are detected by an array of sensing units in Southwestern Arizona. This array extends 108 miles along an east?west segment of a great circle with units placed at 4?mile intervals. From these units transmission lines are routed along the ground to recording stations near Dateland and Gila Bend. A single twin?conductor field line serves from one to three units and may be as long as 40 miles. Over such a line the sensing units are turned on by relays and the signals are transmitted to the recording station. The use of carriers has permitted the separation of multiplexed signals by means of tuning controls. Push?pull condenser?coupled amplifiers drive the Brush recording pens. Sensitivity is controlled in 6?db steps through a range from 5 to 160 dynes per sq cm peak?to?peak for full scale deflection. A pass band from 0.2 to 5 cps is set by an acoustic filter in the sensing unit. Several years of use and development have resulted in a system which has proved to be quite satisfactory.

Quench dynamics in SRF cavities: can we locate the quench origin with 2nd sound?  

SciTech Connect

A newly developed method of locating quenches in SRF cavities by detecting second-sound waves has been gaining popularity in SRF laboratories. The technique is based on measurements of time delays between the quench as determined by the RF system and arrival of the second-sound wave to the multiple detectors placed around the cavity in superfluid helium. Unlike multi-channel temperature mapping, this approach requires only a few sensors and simple readout electronics; it can be used with SRF cavities of almost arbitrary shape. One of its drawbacks is that being an indirect method it requires one to solve an inverse problem to find the location of a quench. We tried to solve this inverse problem by using a parametric forward model. By analyzing the data we found that the approximation where the second-sound emitter is a near-singular source does not describe the physical system well enough. A time-dependent analysis of the quench process can help us to put forward a more adequate model. We present here our current algorithm to solve the inverse problem and discuss the experimental results.

Laboratory Test Report for Fujitsu 12RLS and Mitsubishi FE12NA Mini-Split Heat Pumps  

SciTech Connect

Mini-split heat pumps are being proposed as a new retrofit option to replace resistance heating in the Pacific Northwest. NREL has previously developed a field test protocol for mini-split systems to ensure consistent results from field tests. This report focuses on the development of detailed system performance maps for mini-split heat pumps so that the potential benefits of mini-split systems can be accurately analyzed for different climate regions and housing types. This report presents laboratory test results for two mini-split heat pumps. Steady-state heating and cooling performance for the Fujitsu 12RLS and Mitsubishi FE12NA was tested under a wide range of outdoor and indoor temperatures at various compressor and fan speeds. Cycling performance for each unit was also tested under both modes of operation. Both systems performed quite well under low loads and the experimental test data aligned with manufacturer reported values. Adequate datasets were attained to promote performance modeling of these two systems in the future.

Sound power level measurement of Sheng, a Chinese wind instrument  

Science Journals Connector (OSTI)

Sheng is one of the Chinese traditional wind instruments. But its sound power level has never been carefully measured. In this paper the sound powermeasurements of Sheng were performed for the first time in a reverberation chamber according to ISO standard and Chinese national standard. Two qualified musicians performed on their own instruments in the center of the reverberation chamber. The radiated sound energy and the dynamic ranges of the Sheng were investigated by four channel acoustic measuring equipments. Typical sound power values were obtained through averaging and the results were reported in this paper. It was showed that the mean forte sound power level can reach up to 98dB with a dynamic range of 22.5dB when music scale was performed. The method discussed here is valuable for the sound powermeasurements of other musical instruments. The measurement of the sound power radiated by national musical instruments lays foundations for the investigation into the acoustics of national music halls.

Sound quality descriptors for HVAC equipment from ARI Standards  

Science Journals Connector (OSTI)

The Air Conditioning and Refrigeration Institute (ARI) has several standards that provide methods to evaluate the sound quality of heating ventilating and air?conditioning (HVAC) equipment. These include Standard 270 Sound rating of outdoor unitary equipment Standard 350 Sound rating of non?ducted indoor air?conditioning equipment and Standard 1140P Procedures for evaluating sound quality of HVAC equipment. The preferred method in these standards is best described in Standard 1140P which uses one?third octave band sound power levels that are weighted to adjust for the sensitivity to frequency distribution and presence of tones and are then converted to a single number sound quality indicator. The tone adjustment is based on the projection of a given one?third octave band level relative to the average of the adjacent one?third octave bands. An alternate use of Zwicker method B to determine loudness and loudness level is also provided in ARI Standard 1140P. These standards provide a convenient method by which complex sounds for similar products may be compared.

NREL Documents Efficiency of Mini-Split Heat Pumps (Fact Sheet)  

SciTech Connect

A new report delivers mini-split heat pump (MSHP) performance data for use in whole-building simulation tools. Mini-split heat pumps (MSHPs) are highly efficient refrigerant-based air conditioning and heating systems that permit room-by-room conditioning and control in homes. Because of their size, efficiency, and price, MSHPs are very popular overseas and are gaining market share in energy-efficient home upgrades in the United States. They are a good option for retrofitting older homes that lack ductwork. To evaluate MSHP cost effectiveness and performance in U.S. homes, National Renewable Energy Laboratory (NREL) researchers are studying these systems in the laboratory, simulated buildings, and field test settings. A new NREL report describes an innovative laboratory approach to testing MSHPs and includes experimental performance maps for use in whole-building simulation tools. Most public information on MSHP performance is provided by equipment manufacturers, and is typically limited to performance at a single operating speed for heating and cooling. Mini-split heat pumps use variable speed components that spin up and down to continuously meet the heating or cooling need, significantly improving a system's operating efficiency. Measuring that efficiency in a laboratory is challenging and required new approaches to performance testing. NREL researchers worked with colleagues at Purdue University's Herrick Labs and Ecotope, Inc. to refine and apply this new approach to a suite of MSHP products. Researchers measured the performance of two MSHPs across a variety of operating conditions, which allowed, for the first time, development of accurate building simulation MSHP models. In the laboratory tests, researchers found that both MSHPs achieved manufacturer-reported performance at rating conditions. However, at other temperature and humidity conditions, the heat pumps capacity ranged from 40% above to 54% below the manufacturer-reported values. Knowing how performance varies is critical in order to reasonably estimate annual energy consumption of a MSHP, and to compare MSHPs to other heating and cooling options. Mini-split heat pump efficiency (COP) was seen to significantly exceed rated efficiency at low compressor speeds-a very important effect.

Sound propagation conditions in the equatorial South Pacific Ocean  

Science Journals Connector (OSTI)

A major part of the South Pacific Ocean is impacted by a cold water circulation induced by the Antarctic Circumpolar Current. This results in either a double or a very broad deep sound channel axis [R. N. Denham et al. J. Acoust. Soc. Am. 81 787–789 (1987)]. However nearer the equator this impact is reduced and a series of equatorial currents and counter currents come into play. An analysis is made of existing oceanographic data to determine the resulting sound?speed profile shape and sound channel axis depth. A comparison is made to profiles from the temperate regions of the South Pacific Ocean.

Design and implementation of an underwater sound recording device  

SciTech Connect

The purpose of this study was to design and build two versions of an underwater sound recording device. The device designed is referred to as the Underwater Sound Recorder (USR), which can be connected to one or two hydrophones or other underwater sound sensors. The URS contains a 26 dB preamplifier and a user selectable gain that permits additional amplification of input to the system from 26 dB to 46 dB. Signals within the frequency range up to 15 kHz may be recorded using the USR. Examples of USR applications are monitoring underwater processes that have the potential to create large pressure waves that could potentially harm fish or other aquatic life, such as underwater explosions or pile driving. Additional applications are recording sound generated by vessels or the vocalizations of some marine mammals, such as the calls from many species of whales.

Puget Sound area electric reliability plan  

SciTech Connect

Various conservation, load management, and fuel switching programs were considered as ways to reduce or shift system peak load. These programs operate at the end-use level, such as residential water heat. Figure D-1a shows what electricity consumption for water heat looks like on normal and extreme peak days. Load management programs, such as water heat control, are designed to reduce electricity consumption at the time of system peak. On the coldest day in average winter, system load peaks near 8:00 a.m. In a winter with extremely cold weather, electricity consumption increases fr all hours, and the system peak shifts to later in the morning. System load shapes in the Puget Sound area are shown in Figure D-1b for a normal winter peak day (February 2, 1988) and extreme peak day (February 3, 1989). Peak savings from any program are calculated to be the reduction in loads on the entire system at the hour of system peak. Peak savings for all programs are measured at 8:00 a.m. on a normal peak day and 9:00 a.m. on an extreme peak day. On extremely cold day, some water heat load shifts to much later in the morning, with less load available for shedding at the time of system peak. Models of hourly end-use consumption were constructed to simulate the impact of conservation, land management, and fuel switching programs on electricity consumption. Javelin, a time-series simulating package for personal computers, was chosen for the hourly analysis. Both a base case and a program case were simulated. 15 figs., 7 tabs.

Puget Sound area electric reliability plan. Draft environmental impact statement  

SciTech Connect

The Puget Sound Area Electric Reliability Plan Draft Environmental Impact Statement (DEIS) identifies the alternatives for solving a power system problem in the Puget Sound area. This Plan is undertaken by Bonneville Power Administration (BPA), Puget Sound Power & Light, Seattle City Light, Snohomish Public Utility District No. 1 (PUD), and Tacoma Public Utilities. The Plan consists of potential actions in Puget Sound and other areas in the State of Washington. A specific need exists in the Puget Sound area for balance between east-west transmission capacity and the increasing demand to import power generated east of the Cascades. At certain times of the year, there is more demand for power than the electric system can supply in the Puget Sound area. This high demand, called peak demand, occurs during the winter months when unusually cold weather increases electricity use for heating. The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound`s power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

Structure and Electronic Spectra of DNA Mini-hairpins with Gn:Cn Stems  

SciTech Connect

The research described in this product was performed in part in the Environmental Molecular Sciences Laboratory, a national scientific user facility sponsored by the Department of Energy's Office of Biological and Environmental Research and located at Pacific Northwest National Laboratory. The solution structure of a synthetic DNA mini-hairpin possessing a stilbenediether linker and three G:C base pairs has been obtained using 1H NMR spectral data and constrained torsion angle molecular dynamics. Notable features of this structure include a compact hairpin loop having a short stilbene-guanine plane-toplane distance and approximate B-DNA geometry for the three base pairs. Comparison of the electronic spectra of mini-hairpins having one-to-four G:C base pairs and stilbenediether or hexamethyleneglycol linkers reveals the presence of features in the UV and CD spectra of the stilbene-linked hairpins that are not observed for the ethyleneglycol-linked hairpins. Investigation of the electronic structure of a stilbene-linked hairpin having a single G:C base pair by means of time-dependent density functional theory shows that the highest occupied molecular orbital, but not the lowest unoccupied molecular orbital, is delocalized over the stilbene and adjacent guanine. The calculated UV and CD spectra are highly dependent upon hairpin conformation, but reproduce the major features of the experimental spectra. These results illustrate the utility of an integrated experimental and theoretical approach to understanding the complex electronic spectra of ?-stacked chromophores.

Mini-slot scheduling for IEEE 802.16d chain and grid mesh networks  

Science Journals Connector (OSTI)

This work considers the mini-slot scheduling problem in IEEE 802.16d wireless mesh networks (WMNs). An efficient mini-slot scheduling needs to take into account the transmission overhead, the scheduling complexity, and the signaling overhead to broadcast the scheduling results. We are interested in chain and grid WMNs, which are the basic topologies of many applications. We propose scheduling schemes that are featured by low complexity and low signaling overhead. Compared to existing works, this work contributes in developing low-cost schemes to find periodical and regular schedules that achieve near-optimal transmission latencies by balancing between transmission overhead and pipeline efficiency and that are more practical and easier to implement. To minimize the transmission latency, we model the transmission latency as a function of the transmission size and the subscriber stations’ traffic demands, and take the first-order derivative of the transmission size to find the minimum latency. Simulation results show that our schemes significantly improve over existing works in computational complexity while maintain similar or better transmission latencies.

Investigation of power battery thermal management by using mini-channel cold plate  

Science Journals Connector (OSTI)

Abstract In order to guarantee the safety and extend the cycle life of Li-ion power batteries within electric vehicles, a mini-channel cold plate-based battery thermal management system is designed to cool a rectangular Li-ion battery. A three-dimensional thermal model of the cooling system was established and the effects of number of channels, flow direction, inlet mass flow rate and ambient temperature on temperature rise and distribution of the battery during the discharge process were investigated. The results suggest that the maximum temperature of the battery decreases with increases in the number of channels and inlet mass flow rate. The effect of flow direction on cooling performance was smaller after mass flow rate increased. The cooling performance improved with the increase of inlet mass flow rate but the increasing trend became smaller, and the mass flow rate as 5 × 10?4 kg s?1 was optimal. The simulation results will be useful for the design of mini-channel cold plate-based battery thermal management system.

If LHC is a Mini-Time-Machines Factory, Can We Notice?  

E-Print Network (OSTI)

Assuming the hypothesis of TeV-scale multi-dimensional gravity, one can imagine that at LHC not only mini-black-holes (MBH) will be intensively created, but also other exotic gravitational configurations, including hypothetical mini-time-machines (MTM). Like MBH, they should quickly evaporate, but one can wonder if their temporal existence at the moment of high-energy collision can leave any traces in the observable data. We briefly discuss five thinkable effects: (i) change of the energy spectrum due to the frequency-filtration property of MTM, (ii) possible production of anomalously energetic particles, accelerated by passing many times through gravitational field inside the MTM, (iii) acceleration of particle decays, since the proper time of a particle moving inside MTM can strongly exceed the laboratory time, (iv) CPT and naive unitarity violation (thermalization) due to effective non-local interactions caused by MTM and to possible ambiguity in the population of closed world-lines inside MTM, (v) collective effects due to conversion of a single particle into a bunch of its co-existing copies within the MTM. Despite possible particle-antiparticle conversion inside MTM, they do not seem to produce any specific CP-violation effects.

Increasing the efficiency of thermoacoustic carbon nanotube sound projectors  

Science Journals Connector (OSTI)

Carbon nanotubes (CNTs) can generate smooth-spectra sound emission over a wide frequency range (1–105 Hz) by means of thermoacoustics (TA). However, in the low frequencies f, where the need for large area sound projectors is high, the sound generation efficiency ? of open CNT sheets is low, since ? ? f2. Together with this problem, the nanoscale thickness of CNT sheets, their high sensitivity to the environment and the high surface temperatures useful for TA sound generation are other drawbacks, which we address here by protective encapsulation of free-standing CNT sheets in inert gases. We provide an extensive experimental study of such closed systems for different thermodynamic regimes and rationalize our observations within a basic theoretical framework. The observed sound pressure levels for encapsulated argon filled TA transducers (130 dB in air and 200 dB underwater in the near field at 5 cm distance, and 100 and 170 dB in the far field at 1 m distance) are Q times higher than those for open systems, where Q is the resonant quality factor of the thin enclosure plates. Moreover, the sound generation efficiency of the encapsulated system increases toward low frequencies (? ? 1/f2). Another method to increase ? in the low frequency region is by modulation of the applied high frequency carrier current with a low frequency resonant envelope. This approach enables sound generation at the frequency of the applied current without the need for additional energy-consuming biasing. The acoustical and geometrical parameters providing further increases in efficiency and transduction performance for resonant systems are discussed.

Four Momentum Transfer Discrepancy in the Charged Current ? plus; Production in the MiniBooNE: Data vs. Theory  

Science Journals Connector (OSTI)

The MiniBooNE experiment has collected what is currently the world’s largest sample of v ? charged current single charged pion (CC1? + ) interactions roughly 46 000 events. The purity of the (CC1? + ) sample is 87% making this the purest event sample observed in the MiniBooNE detector [1]. The average energy of neutrinos producing (CC1? + ) interactions in MiniBooNE is about 1?GeV[2] therefore the study of these events can provide insight into both resonant and coherent pion production processes. In this talk we will discuss the long?standing discrepancy in four?momentum transfer observed between (CC1? + ) data and existing predictions. Several attempts to address this problem will be presented. Specifically the Rein?Sehgal [3 4] model has been extended to include muon mass terms for both resonant [5 6] and coherent [7] production. Using calculations from [8] an updated form for the vector form factor [9] has also been adopted. The results of this improved description of (CC1? + ) production will be compared to the high statistics MiniBooNE (CC1? + ) data and several existing parametrisations of the axial vector form factor [8 9 11].

Letter of Intent to Build a MiniBooNE Near Detector:BooNE  

SciTech Connect

There is accumulating evidence for a difference between neutrino and antineutrino oscillations at the {approx}1 eV{sup 2} scale. The MiniBooNE experiment observes an unexplained excess of electron-like events at low energies in neutrino mode, which may be due, for example, to either a neutral current radiative interaction, sterile neutrino decay, or to neutrino oscillations involving sterile neutrinos and which may be related to the LSND signal. No excess of electron-like events (-0.5 {+-} 7.8 {+-} 8.7), however, is observed so far at low energies in antineutrino mode. Furthermore, global 3+1 and 3+2 sterile neutrino fits to the world neutrino and antineutrino data suggest a difference between neutrinos and antineutrinos with significant (sin{sup 2} 2{theta}{sub {mu}{mu}} {approx} 35%) {bar {nu}}{sub {mu}} disappearance. In order to test whether the low-energy excess is due to neutrino oscillations and whether there is a difference between {nu}{sub {mu}} and {bar {nu}}{sub {mu}} disappearance, we propose building a second MiniBooNE detector at (or moving the existing MiniBooNE detector to) a distance of {approx}200 m from the Booster Neutrino Beam (BNB) production target. With identical detectors at different distances, most of the systematic errors will cancel when taking a ratio of events in the two detectors, as the neutrino flux varies as 1/r{sup 2} to a calculable approximation. This will allow sensitive tests of oscillations for both {nu}{sub e} and {bar {nu}} appearance and {nu}{sub {mu}} and {bar {nu}}{sub {mu}} disappearance. Furthermore, a comparison between oscillations in neutrino mode and antineutrino mode will allow a sensitive search for CP and CPT violation in the lepton sector at short baseline ({Delta}m{sup 2} > 0.1 eV{sup 2}). Finally, by comparing the rates for a neutral current (NC) reaction, such as NC {pi}{sup 0} scattering or NC elastic scattering, a direct search for sterile neutrinos will be made. The initial amount of running time requested for the near detector will be a total of {approx}2E20 POT divided between neutrino mode and antineutrino mode, which will provide statistics comparable to what has already been collected in the far detector. A thorough understanding of this short-baseline physics will be of great importance to future long-baseline oscillation experiments.

Sound Waves in the Atmosphere at Infrasonic Frequencies  

Science Journals Connector (OSTI)

Various geophysical processes generate sound waves in the atmosphere. Some typical sources are auroral discharges in the upper atmosphere tornadoes and severe storms surface waves on the oceans volcanic explosions earthquakes and atmospheric oscillations arising from unstable wind flow at the tropopause. Man?made sources include powerful explosions and the shock waves from vehicles moving at supersonic speeds at altitudes below about 125 km. The components of sound?wave energy at infrasonic frequencies (oscillation periods >1.0 sec) are propagated for large distances (thousands of kilometers) over the earth's surface with very little loss of energy from absorption by viscosity and heat conduction. But the propagation depends strongly on (a) the horizontally stratified temperature structure of the atmosphere (b) the influence of gravity at oscillation periods greater than the atmospheric resonance period ?300 sec and (c) the nonuniform distribution of atmospheric winds. The microphones and electroacoustical apparatus at an infrasonics observation station e.g. the one at Washington D. C. measure (1) the amplitude and waveform of incident sound pressure (2) the direction of local propagation of the wave (3) the horizontal trace velocity and (4) the distribution of sound wave energy at various oscillation frequencies. Researches on propagation require observational data from a network of stations separated geographically by large distances coupled with theoretical analysis of sound propagation to arrive at useful results on the acoustics of the atmosphere.

Airborne sound propagation over sea during offshore wind farm piling  

Science Journals Connector (OSTI)

Offshore piling for wind farm construction has attracted a lot of attention in recent years due to the extremely high noise emission levels associated with such operations. While underwater noise levels were shown to be harmful for the marine biology the propagation of airborne piling noise over sea has not been studied in detail before. In this study detailed numerical calculations have been performed with the Green's Function Parabolic Equation (GFPE) method to estimate noise levels up to a distance of 10?km. Measured noise emission levels during piling of pinpiles for a jacket-foundation wind turbine were assessed and used together with combinations of the sea surface state and idealized vertical sound speed profiles (downwind sound propagation). Effective impedances were found and used to represent non-flat sea surfaces at low-wind sea states 2 3 and 4. Calculations show that scattering by a rough sea surface which decreases sound pressure levels exceeds refractive effects which increase sound pressure levels under downwind conditions. This suggests that the presence of wind even when blowing downwind to potential receivers is beneficial to increase the attenuation of piling sound over the sea. A fully flat sea surface therefore represents a worst-case scenario.

Transmission of sound through suspended ceilings from HVAC terminal units  

Science Journals Connector (OSTI)

An ASHRAE project to investigate factors determining the sound pressure levels in rooms below ceilings concealing air?terminal units has been completed. Four terminal units installed close to the six ceiling types used were the major noise sources. They were supplemented by two simulators powered by loudspeakers. Sound power was measured for each device in the 156 cubic meter test room in its reverberant condition. The levels in the room were measured for each combination of source and ceiling tile. Sound pressure level was measured as a function of distance from two sources in the room below. The main intent of the project was to validate ARI Standard 885 which provides a calculation method for such situations. Differences among ceiling types were less than expected; leakage around the edges of each panel is a dominant transmission path. Ceiling attenuations at low frequencies were found to depend on the area of the lower face of the units. Sound levels in the room were essentially uniform when the source was above the ceiling. The decay of sound with distance from the sources below the ceiling was found to depend on the inverse of the room reverberation time.

Mini ball grid array (mBGA) assembly on MCM-L boards  

SciTech Connect

Sandia National Laboratories has developed a chip scale packaging technology called mini Ball Grid Array (mBGA). The mBGA is a flip chip die, obtained by redistributing peripheral pads in existing dies to an area array of pads 10 mils or larger in diameter with a minimum pitch of 20 mils. The peripheral pads are redistributed to area array pads using two polyimide dielectric and two metal conductor layers. mBGA can be closely tiled together on a substrate to yield a very high circuit density. In an earlier report, the authors presented the results on the reliability and thermal performance of mBGA on silicon and ceramic substrates.

Summary of the LARP Mini-Workshop on Beam-Beam Compensation 2007  

SciTech Connect

The LARP Mini-Workshop on Beam-Beam Compensation 2007 was held at SLAC, 2-4 July 2007. It was attended by 33 participants from 10 institutions in Asia, Europe, and America. 26 presentations were given, while more than one third of the time was allocated to discussions. The workshop web site is Ref. [1]. The workshop's main focus was on long-range and head-on beam-beam compensation, with a view towards application in the LHC. Other topics included the beam-beam performance of previous, existing and future circular colliders; beam-beam simulations; new operating modes, theory, and unexplained phenomena. This summary is also published as Ref. [2].

Long-Term Monitoring of Mini-Split Ductless Heat Pumps in the Northeast  

SciTech Connect

Transformations, Inc. has extensive experience building their high performance housing at a variety of Massachusetts locations, in both a production and custom home setting. The majority of their construction uses mini-split heat pumps (MSHPs) for space conditioning. This research covered the long-term performance of MSHPs in Zone 5A; it is the culmination of up to three years' worth of monitoring in a set of eight houses. This research examined electricity use of MSHPs, distributions of interior temperatures and humidity when using simplified (two-point) heating systems in high performance housing, and the impact of door open/closed status on temperature distributions. The use of simplified space conditioning distribution (MSHPs) provides significant first cost savings, which are used to offset the increased investment in the building enclosure.

TURBULENCE AND RADIO MINI-HALOS IN THE SLOSHING CORES OF GALAXY CLUSTERS  

SciTech Connect

A number of relaxed, cool-core galaxy clusters exhibit diffuse, steep-spectrum radio sources in their central regions, known as radio mini-halos. It has been proposed that the relativistic electrons responsible for the emission have been reaccelerated by turbulence generated by the sloshing of the cool core gas. We present a high-resolution MHD simulation of gas sloshing in a galaxy cluster coupled with subgrid simulations of relativistic electron acceleration to test this hypothesis. Our simulation shows that the sloshing motions generate turbulence on the order of {delta}v {approx} 50-200 km s{sup -1} on spatial scales of {approx}50-100 kpc and below in the cool core region within the envelope of the sloshing cold fronts, whereas outside the cold fronts, there is negligible turbulence. This turbulence is potentially strong enough to reaccelerate relativistic electron seeds (with initial {gamma} {approx} 100-500) to {gamma} {approx} 10{sup 4} via damping of magnetosonic waves and non-resonant compression. The seed electrons could remain in the cluster from, e.g., past active galactic nucleus activity. In combination with the magnetic field amplification in the core, these electrons then produce diffuse radio synchrotron emission that is coincident with the region bounded by the sloshing cold fronts, as indeed observed in X-rays and the radio. The result holds for different initial spatial distributions of pre-existing relativistic electrons. The power and the steep spectral index ({alpha} Almost-Equal-To 1-2) of the resulting radio emission are consistent with observations of mini-halos, though the theoretical uncertainties of the acceleration mechanisms are high. We also produce simulated maps of inverse-Compton hard X-ray emission from the same population of relativistic electrons.

Improving sound propagation modeling for wind power projects  

Science Journals Connector (OSTI)

Sound propagation from wind power projects can be modeled in the same manner as other more common outdoor noisesources but are these models suited to wind turbines' uniquely high source heights operating under high wind conditions and various degrees of terrain ruggedness. In "Propagation Modeling Parameters for Wind Turbines" (K. Kaliski and E. Duncan Proceedings of Institute of Noise ControlEngineers NOISECON 2007) the effects of ground attenuation and various adjustments for wind conditions on sound propagationmodeling were discussed. This paper continues the discussion and explores the accuracy of existing sound propagationmodeling methods for wind power projects including ISO 9613 and other standards. Model data for wind power projects and the implications of various terrain and ground coverage will be discussed.

Thermo-acoustic Sound Generation in the Interaction of Pulsed Proton and Laser Beams with a Water Target  

E-Print Network (OSTI)

The generation of hydrodynamic radiation in interactions of pulsed proton and laser beams with matter is explored. The beams were directed into a water target and the resulting acoustic signals were recorded with pressure sensitive sensors. Measurements were performed with varying pulse energies, sensor positions, beam diameters and temperatures. The obtained data are matched by simulation results based on the thermo-acoustic model with uncertainties at a level of 10%. The results imply that the primary mechanism for sound generation by the energy deposition of particles propagating in water is the local heating of the medium. The heating results in a fast expansion or contraction and a pressure pulse of bipolar shape is emitted into the surrounding medium. An interesting, widely discussed application of this effect could be the detection of ultra-high energetic cosmic neutrinos in future large-scale acoustic neutrino detectors. For this application a validation of the sound generation mechanism to high accur...

Concentration and toxicity of sea-surface contaminants in Puget Sound  

SciTech Connect

The Marine Research Laboratory conducted studies during CY 1985 to evaluate the effects of sea-surface contamination on the reproductive success of a valued marine species. Microlayer and bulk water samples were collected from a rural bay, central Puget Sound, and three urban bays and analyzed for a number of metal and organic contaminants as well as for densities of neuston and plankton organisms. Fertilized neustonic eggs of sand sole (Psettichthys melanostictus) were exposed to the same microlayer samples during their first week of embryonic and larval development. Also, we evaluated the effects of microlayer extracts on the growth of trout cell cultures. Compared to rural sites, urban bays generally contained lower densities of neustonic flatfish eggs during the spawning season. Also, in contrast to the rural sites or the one central Puget Sound site, approximately half of the urban bay microlayer samples resulted in significant increases in embryo mortality (up to 100%), kyphosis (bent spine abnormalities) in hatched larvae, increased anaphase aberrations in developing embryos, and decreased trout cell growth. The toxic samples generally contained high concentrations of polycyclic aromatic and/or chlorinated hydrocarbons and/or potentially toxic metals. In some cases, concentrations of contaminants on the sea surface exceeded water-quality criteria by several orders of magnitude. Several samples of subsurface bulk water collected below highly contaminated surfaces showed no detectable contamination or toxicity.

Testing Thermo-acoustic Sound Generation in Water with Proton and Laser Beams  

E-Print Network (OSTI)

Experiments were performed at a proton accelerator and an infrared laser acility to investigate the sound generation caused by the energy deposition of pulsed particle and laser beams in water. The beams with an energy range of 1 PeV to 400 PeV per proton beam spill and up to 10 EeV for the laser pulse were dumped into a water volume and the resulting acoustic signals were recorded with pressure sensitive sensors. Measurements were performed at varying pulse energies, sensor positions, beam diameters and temperatures. The data is well described by simulations based on the thermo-acoustic model. This implies that the primary mechanism for sound generation by the energy deposition of particles propagating in water is the local heating of the media giving rise to an expansion or contraction of the medium resulting in a pressure pulse with bipolar shape. A possible application of this effect would be the acoustical detection of neutrinos with energies greater than 1 EeV.

Measurement of sound speed vs. depth in South Pole ice: pressure waves and shear waves  

SciTech Connect

We have measured the speed of both pressure waves and shear waves as a function of depth between 80 and 500 m depth in South Pole ice with better than 1% precision. The measurements were made using the South Pole Acoustic Test Setup (SPATS), an array of transmitters and sensors deployed in the ice at the South Pole in order to measure the acoustic properties relevant to acoustic detection of astrophysical neutrinos. The transmitters and sensors use piezoceramics operating at {approx}5-25 kHz. Between 200 m and 500 m depth, the measured profile is consistent with zero variation of the sound speed with depth, resulting in zero refraction, for both pressure and shear waves. We also performed a complementary study featuring an explosive signal propagating vertically from 50 to 2250 m depth, from which we determined a value for the pressure wave speed consistent with that determined for shallower depths, higher frequencies, and horizontal propagation with the SPATS sensors. The sound speed profile presented here can be used to achieve good acoustic source position and emission time reconstruction in general, and neutrino direction and energy reconstruction in particular. The reconstructed quantities could also help separate neutrino signals from background.

Wind turbine sound prediction - the consequence of getting it wrong  

Science Journals Connector (OSTI)

The application to permit a wind turbine power development usually involves submission of a prediction for the sound level that will occur at residences schools places of worship and elsewhere people gather for restorative rest. This paper uses the example of a wind power development and follows iterations taken to finalize the sound level prediction. The paper provides quantitative information collected since the start up of the wind power development on measured sound levels and octave band distribution; and qualitative observations on the special characteristics of the sound. Actual observations are compared to the predictions. More importantly the paper reviews the consequences self-reported in qualitative interviews by citizens living with the changed environment after four years of operation of the wind power development. Reported impacts included difficulty sleeping loss of jobs and changes to social relationships caregiving pursuit of hobbies leisure learning and overall health. Changes in measured health outcomes are identified. Both the quantitative and qualitative findings justify revision of the permitting process.

The science of underwater sound: Education, communication, and outreach  

Science Journals Connector (OSTI)

As a complex scientific topic underwater sound can be challenging for scientists to discuss and effectively communicate with non-science audiences. Educational audiences span formal K-16 classrooms to museum and aquarium visitors. The science of sound is often included in upper middle school physical sciences curricula high school physics classes and undergraduate and graduate university courses which can take advantage of calculus to support student understanding. Communicating with the media presents other challenges: pressing or immediate deadlines; a need to deliver eye-catching flashy pieces that capture reader attention; and a general lack of fundamental knowledge of underwater sound by readers. Scientists must be proactive in their engagement with media to ensure good fundamental science is communicated and to increase useful stories about new developments in underwater sound research. Regulators and other decision-makers are also pressed for time when contemplating a topic yet they need the most up-to-date scientific findings to support their decision-making. This talk will provide an overview of the challenges that ocean acoustic specialists face when trying to communicate the results of their research and meet the needs of diverse audiences. In addition strategies and possible solutions will be discussed.

On the evolution of controllers for sound spatialization  

Science Journals Connector (OSTI)

Dynamic changes in spatialsound attributes have played a role in classical Western music for a long time. It is known that choreographic movements of operasingers were sometimes made for acoustic considerations. Probably the first mechanical spatialsound controller is the so?called wind swell that is found in pipe organs. Already in 1712 Renatus Harris mentions how swelling enables the player to project the sound of the pipes ad libitum to nearby or further distances. With the invention of electroacoustic music a number of electromechanical devices were developed to control spatial aspects of sound (primarily positioning sound sources in 3?D space). Typical examples are Stockhausen’s rotational table (developed in the 1950s) and Manfred Krause’s sound mill (1960). In this presentation the evolutionary steps in the design of spatialsound controllers will be outlined—beginning with early purely mechanical devices up to recent approaches including the author’s participation in the development of a gestural controllable soundsystem based on virtual microphone control (ViMiC).

MiniGhost : a miniapp for exploring boundary exchange strategies using stencil computations in scientific parallel computing.  

SciTech Connect

A broad range of scientific computation involves the use of difference stencils. In a parallel computing environment, this computation is typically implemented by decomposing the spacial domain, inducing a 'halo exchange' of process-owned boundary data. This approach adheres to the Bulk Synchronous Parallel (BSP) model. Because commonly available architectures provide strong inter-node bandwidth relative to latency costs, many codes 'bulk up' these messages by aggregating data into a message as a means of reducing the number of messages. A renewed focus on non-traditional architectures and architecture features provides new opportunities for exploring alternatives to this programming approach. In this report we describe miniGhost, a 'miniapp' designed for exploration of the capabilities of current as well as emerging and future architectures within the context of these sorts of applications. MiniGhost joins the suite of miniapps developed as part of the Mantevo project.

A Measurement of the muon neutrino charged current quasielastic interaction and a test of Lorentz violation with the MiniBooNE experiment  

SciTech Connect

The Mini-Booster neutrino experiment (MiniBooNE) at Fermi National Accelerator Laboratory (Fermilab) is designed to search for {nu}{sub {mu}} {yields} {nu}{sub e} appearance neutrino oscillations. Muon neutrino charged-current quasi-elastic (CCQE) interactions ({nu}{sub {mu}} + n {yields} {mu} + p) make up roughly 40% of our data sample, and it is used to constrain the background and cross sections for the oscillation analysis. Using high-statistics MiniBooNE CCQE data, the muon-neutrino CCQE cross section is measured. The nuclear model is tuned precisely using the MiniBooNE data. The measured total cross section is {sigma} = (1.058 {+-} 0.003 (stat) {+-} 0.111 (syst)) x 10{sup -38} cm{sup 2} at the MiniBooNE muon neutrino beam energy (700-800 MeV). {nu}{sub e} appearance candidate data is also used to search for Lorentz violation. Lorentz symmetry is one of the most fundamental symmetries in modern physics. Neutrino oscillations offer a new method to test it. We found that the MiniBooNE result is not well-described using Lorentz violation, however further investigation is required for a more conclusive result.

A measurement of the neutral current neutrino-nucleon elastic cross section at MiniBooNE  

SciTech Connect

The neutral current neutrino-nucleon elastic interaction {nu} N {yields} {nu} N is a fundamental process of the weak interaction ideally suited for characterizing the structure of the nucleon neutral weak current. This process comprises {approx}18% of neutrino events in the neutrino oscillation experiment, MiniBooNE, ranking it as the experiment's third largest process. Using {approx}10% of MiniBooNE's available neutrino data, a sample of these events were identified and analyzed to determine the differential cross section as a function of the momentum transfer of the interaction, Q{sup 2}. This is the first measurement of a differential cross section with MiniBooNE data. From this analysis, a value for the nucleon axial mass M{sub A} was extracted to be 1.34 {+-} 0.25 GeV consistent with previous measurements. The integrated cross section for the Q{sup 2} range 0.189 {yields} 1.13 GeV{sup 2} was calculated to be (8.8 {+-} 0.6(stat) {+-} 0.2(syst)) x 10{sup -40} cm{sup 2}.

Habitable Evaporated Cores: Transforming Mini-Neptunes into Super-Earths in the Habitable Zones of M Dwarfs  

E-Print Network (OSTI)

We show that photoevaporation of small gaseous exoplanets ("mini-Neptunes") in the habitable zones of M dwarfs can remove several Earth masses of hydrogen and helium from these planets and transform them into potentially habitable worlds. We couple X-ray/extreme ultraviolet (XUV)-driven escape, thermal evolution, tidal evolution and orbital migration to explore the types of systems that may harbor such "habitable evaporated cores" (HECs). We find that HECs are most likely to form from planets with $\\sim 1 M_\\oplus$ solid cores with up to about 50% H/He by mass, though whether or not a given mini-Neptune forms a HEC is highly dependent on the early XUV evolution of the host star. As terrestrial planet formation around M dwarfs by accumulation of local material is likely to form planets that are small and dry, evaporation of small migrating mini-Neptunes could be one of the dominant formation mechanisms for volatile-rich Earths around these stars.

Parametric design study of ``mini-generator`` with 6-watt heat source  

SciTech Connect

The Fairchild study showed that generator designs based on a single 1-watt RHU had very poor thermal efficiencies. At their optimum operating point, more than half of the generated heat was lost through the thermal insulation. This resulted in system efficiency of only 2.2%, compared to 7.2% for current Radioisotope Thermoelectric Generators (RTGs). Moreover, there were serious doubts about the fabricability of the required multicouples, particularly of the series/parallel connections between the large number (900) of thermoelectric legs of very small cross-section (0.21 mm square). All in all, the preceding paper showed that neither JPL`s Power Stick design nor the Fairchild-generated derivatives based on the 1-watt heat source looked promising. The present paper describes a similar parametric study of a mini-generator based on a 6-watt heat source, and compares its performance and fabricability to that of the optimum Power Stick derivative and of the current RTG design for the same mission. {copyright} 1995 {ital American} {ital Institute} {ital of} {ital Physics}

Theoretical performance of solar cell based on mini-bands quantum dots  

SciTech Connect

The tremendous amount of research in solar energy is directed toward intermediate band solar cell for its advantages compared with the conventional solar cell. The latter has lower efficiency because the photons have lower energy than the bandgap energy and cannot excite mobile carriers from the valence band to the conduction band. On the other hand, if mini intermediate band is introduced between the valence and conduction bands, then the smaller energy photons can be used to promote charge carriers transfer to the conduction band and thereby the total current increases while maintaining a large open circuit voltage. In this article, the influence of the new band on the power conversion efficiency for structure of quantum dots intermediate band solar cell is theoretically investigated and studied. The time-independent Schrödinger equation is used to determine the optimum width and location of the intermediate band. Accordingly, achievement of a maximum efficiency by changing the width of quantum dots and barrier distances is studied. Theoretical determination of the power conversion efficiency under the two different ranges of QD width is presented. From the obtained results, the maximum power conversion efficiency is about 70.42%. It is carried out for simple cubic quantum dot crystal under fully concentrated light. It is strongly dependent on the width of quantum dots and barrier distances.

Implementation and Optimization of miniGMG - a Compact Geometric Multigrid Benchmark  

SciTech Connect

Multigrid methods are widely used to accelerate the convergence of iterative solvers for linear systems used in a number of different application areas. In this report, we describe miniGMG, our compact geometric multigrid benchmark designed to proxy the multigrid solves found in AMR applications. We explore optimization techniques for geometric multigrid on existing and emerging multicore systems including the Opteron-based Cray XE6, Intel Sandy Bridge and Nehalem-based Infiniband clusters, as well as manycore-based architectures including NVIDIA's Fermi and Kepler GPUs and Intel's Knights Corner (KNC) co-processor. This report examines a variety of novel techniques including communication-aggregation, threaded wavefront-based DRAM communication-avoiding, dynamic threading decisions, SIMDization, and fusion of operators. We quantify performance through each phase of the V-cycle for both single-node and distributed-memory experiments and provide detailed analysis for each class of optimization. Results show our optimizations yield significant speedups across a variety of subdomain sizes while simultaneously demonstrating the potential of multi- and manycore processors to dramatically accelerate single-node performance. However, our analysis also indicates that improvements in networks and communication will be essential to reap the potential of manycore processors in large-scale multigrid calculations.

Velocity of sound in relativistic heavy-ion collisions  

Science Journals Connector (OSTI)

We have studied the rapidity distribution of secondary hadrons produced in nucleus-nucleus collisions at ultrarelativistic energies within the ambit of the Landau’s hydrodynamical model. A reasonable description of the data can also be obtained by using the Bjorken’s hydrodynamical model if the boost invariance is restricted to a finite rapidity range. The sensitivity of the hadronic spectra on the equation of state vis-à-vis the velocity of sound has been discussed. The correlation between the velocity of sound and the freeze-out temperature has been indicated. The effects of the nonzero widths of various mesonic and baryonic degrees of freedom up to the mass value ?2.5GeV are seen to be small.

Processing of prosthetic heart valve sounds for classification. Revision 1  

SciTech Connect

People with serious heart conditions have had their expected life span extended considerably with the development of the prosthetic heart valve especially with the great strides made in valve design. Even though the designs are extremely reliable, the valves are mechanical and operating continuously over a long period, therefore, structural failures can occur due to fatigue. Measuring heart sounds non-invasively in a noisy environment puts more demands on the signal processing to extract the desired signals from the noise. In this paper the authors discuss acoustical signal processing techniques developed to process noisy heart valve sounds measured by a sensitive, surface contact microphone and used for the eventual classification of the valve.

Sound radiation due to rapid deformation of an impacted plate  

Science Journals Connector (OSTI)

Sound radiation due to forced deformation of an impacted plate was investigated. An initial sound pressure pulse due to rapid local deformation of a plate was generated before the radiation from natural modes of the plate occurred. On the axis of impact near the plate a distinct pressure pulse is observed to reproduce the velocity waveform of the plate at the opposite side of the impact point. Data from experiments involving impact of spheres on plates differing in size and material properties are presented to show the plate behavior and the radiated soundpressure. Theoretical results were obtained from an analytical model in which impulsive acceleration of a plate with Gaussian spatial distribution is convoluted with the acceleration?time history of the actual impact. Theoretical results for the on?axis pressure are compared with the experimental results.

Near-Field Imaging with Sound: An Acoustic STM Model  

Science Journals Connector (OSTI)

The invention of scanning tunneling microscopy(STM) 30 years ago opened up a visual window to the nano-world and sparked off a bunch of new methods for investigating and controlling matter and its transformations at the atomic and molecular level.1 However an adequate theoretical understanding of the method is demanding; STM images can be considered quantum theory condensed into a pictorial representation. A hands-on model is presented for demonstrating the imaging principles in introductory teaching. It uses sound waves and computer visualization to create mappings of acoustic resonators. The macroscopic simile is made possible by quantum-classical analogies between matter and sound waves. Grounding STM in acoustic experience may help to make the underlying quantum concepts such as tunneling less abstract to students.

Generation of Sound Bullets with a Nonlinear Acoustic Lens  

E-Print Network (OSTI)

Acoustic lenses are employed in a variety of applications, from biomedical imaging and surgery, to defense systems, but their performance is limited by their linear operational envelope and complexity. Here we show a dramatic focusing effect and the generation of large amplitude, compact acoustic pulses (sound bullets) in solid and fluid media, enabled by a tunable, highly nonlinear acoustic lens. The lens consists of ordered arrays of granular chains. The amplitude, size and location of the sound bullets can be controlled by varying static pre-compression on the chains. We support our findings with theory, numerical simulations, and corroborate the results experimentally with photoelasticity measurements. Our nonlinear lens makes possible a qualitatively new way of generating high-energy acoustic pulses, enabling, for example, surgical control of acoustic energy.

A dynamic technique was used because static techniques, which are capable of greater precision, fail at a relatively low temperature. Measurements have been made, and results are shown for enthalpy, temperature, density, electrical resistivity, and sound speed up to 3950 K in iron and 4250 K in nickel.

Superfluid He4 is interesting acoustically because it can support more than one mode of sound propagation, and these can be used to study critical properties. Recently, there has been interest in superfluid-filled aerogels, but for such compressible materials one does not observe the ordinary (fourth) sound; instead there is a mode intermediate between first and fourth sound and a second-sound-like mode. We present a theory for the modes and the first observation of the aerogel second-sound-like mode, which is important because it propagates near the critical temperature.

Experimental study on sound absorbing performance of rubber crumb  

Science Journals Connector (OSTI)

The present paper describes an experimental campaign aimed at the determination of acoustical properties of vulcanized rubber crumbs obtained by the shredding of used tires. In particular their performance as sound absorbing material in lined ducts was investigated. The most innovative aspect that is addressed in the study is the use of a waste material such as rubber tires reduced into small grains as a sound absorbing material: tires are in fact usually used at the end of their life cycle as fuel and burned in cement kilns in order to take advantage of their high heating value with all the problems of pollution that this solution produces. Two kinds of rubber crumbs have been investigated in terms of characteristic dimension of the grains porosity and sound absorbing coefficient while their "in situ" performance when used inside lined and parallel-baffle rectangular ducts has been evaluated measuring their insertion loss. The results of this research show that the acoustical behaviour of the tested rubber crumbs is the typical behaviour of the granular materials showing a noteworthy performance of the tested material in the low frequency range opening a scenery of possible applications where noise has relevant tonal components below 315 Hz.

Low?frequency sound radiation and scattering from bubble clouds.  

Science Journals Connector (OSTI)

Recent experimental evidence has shown that when wave breaking occurs low?frequency (LF?200 Hz) sound is produced and LF scatter has a different characteristic than expected from rough sea surface scattering. These effects have been attributed to the bubbles produced during wave breaking which are convected to depth by the breaking turbulence vorticity and Langmuir circulation as observed by Thorpe [S. Thorpe Oceanic White Caps edited by E. Monahan and G. MacNiocaill (Reidel Boston 1986) pp. 57–58]. While the radiation and scatteringcharacteristics at frequencies greater than 1 kHz are explained by incoherent scatter from the observed bubble size and space distributions the lower frequency phenomena are not easily explained. However if bubble plumes and clouds produced in the wave breaking have appreciable volume fractions (?10?5) then LF sound radiation and scattering can be explained by classical theories. This paper reviews the scattering and radiation from bubbleclouds in water as a function of volume fraction. When the cloud is compact coherent and collective scatter are shown to occur. The natural frequency of radiation is shown to be described by a modified Minnaert result while the backscatter target strength is described by the first?order volume mode. These analytical results agree with experimental sound radiation and scatter measurements. Finally the collective radiation of bubble plumes and clouds is discussed as a possible explanation of the observed ocean low?frequency scattering and radiation phenomena.

Thermoacoustic sound projectors using carbon nanotubes and other nanostructures  

Science Journals Connector (OSTI)

The application of solid-state fabricated carbon nanotube sheets as thermoacoustic (TA) projectors is extended from air to underwater applications. Due to non-resonant sound generation the emission spectrum of nanotube sheets in air or underwater varies smoothly over a wide frequency range 1-105 Hz. Encapsulating the nanotube sheet projectors using inert gases with low heat capacity provided attractive performance at needed low frequencies as well as a realized energy conversion efficiency in air of 0.2% and 1.5% underwater which can be enhanced by further increasing the modulation temperature. We suggest enhancement of sound generation efficiency of encapsulated device by using high quality resonant acoustical windows and modulation of high frequency carrier current with a low frequency resonant envelope. Applications of TA projectors for high power sonar arrays and transparent flexible loudspeakers will be discussed. Finally the alternative nanostructures for excitation of thermoacoustic sound waves will be surveyed. [We gratefully acknowledge support by Office of Naval Research grant N00014-13-1-0180.

Electromagnetic soundings over a geothermal reservoir in Dixie Valley, Nevada  

SciTech Connect

An electromagnetic (EM) sounding survey was performed over a region encompassing the Dixie Valley geothermal field with the purpose of mapping the subsurface resistivity in the geothermal field and its surroundings. The EM survey consisted of 19 frequency-domain depth soundings made with the EM-60 system using three separate horizontal-loop transmitters, and was designed to explore a narrow region adjacent to the Stillwater Range to a depth of 2 to 3 k. Most sounding curves could be fitted to three-layer resistivity models. The surface layer is moderately conductive (10 to 15 ohm-m), has a maximum thickness of 500 m, and consists mainly of alluvial fan and lake sediments. More conductive zones are associated with hydrothermally altered rocks; a resistivity high may be associated with siliceous hot spring deposits. The conductive second layer (2 to 5 ohm-m) varies in thickness from 400 to 800 m and thickens toward the center of the valley. This layer probably consists of lacustrine sediments saturated with saline waters. Local resistivity lows observed in the second layer may be related to elevated subsurface temperatures. This layer may act as a cap rock for the geothermal system. Resistivities of the third layer are high (50 to 100 ohm-m) except in a narrow 5-km band paralleling the range front. This low-resistivity zone, within volcanic rocks, correlates well in depth and location with reported zones of geothermal fluid production. It also seems to correlate with the western margin of a concealed graben structure previously inferred from other geophysical data.

On Heating of Cluster Cooling Flows by Sound Waves  

E-Print Network (OSTI)

We investigate heating of the cool core of a galaxy cluster through the dissipation of sound waves excited by the activities of the central active galactic nucleus (AGN). Using a weak shock theory, we show that this heating mechanism alone cannot reproduce observed temperature and density profiles of a cluster, because the dissipation length of the waves is much smaller than the size of the core and thus the wave energy is not distributed to the whole core. However, we find that if it is combined with thermal conduction from the hot outer layer of the cluster, the wave heating can reproduce the observational results.

Spatial coherence measurement of sound in the northwest Pacific Ocean  

Science Journals Connector (OSTI)

An experiment on the transverse horizontal spatial coherence of sound propagating in the ocean was performed jointly by Chinese and Russian acousticians in the northwest Pacific Ocean in June 1990. Three hydrophones with spacings of 270 and 130 m were put in the water at a 30?m depth. The acoustic source with four cw (from 109 to 860 Hz) and a broadband pseudorandom noise signal was drifted at a depth of 100 m. Part of the measurement results of up to 140 km are presented in this paper. It seems that the spatial coherence was related to the amplitude of the received signals and rises considerably in convergence zones.

Zero sound modes of dilute Fermi gases with arbitrary spin  

Science Journals Connector (OSTI)

Motivated by the recent success of optical trapping of alkali-metal bosons, we have studied the zero sound modes of dilute Fermi gases with arbitrary spin-f, which are spin-S excitations (0<~S<~2f). The dispersion of the mode (S) depends on a single Landau parameter F(S), which is related to the scattering lengths of the system through a simple formula. Measurement of (even a subset of) these modes in finite magnetic fields will enable one to determine all the interaction parameters of the system.

The sound quality of vehicle interior noise: a challenge for the NVH-engineers  

Science Journals Connector (OSTI)

The sound quality of vehicle interior noise has become a very important task for the acoustic engineers since more than 20 years. As vehicles become more and more quiet, the customer's sensitiveness for the acoustical comfort increases. On the one hand, no disturbing noises should be heard and on the other hand, the perceived sound quality, for example from the powertrain, should fulfill the expectations of the listener with respect to the sound design. The development of a good sound quality is in conflict with other targets. The development time of a new car has to be reduced and the production costs have to be lower, the total weight of the car should not increase â?? without any negative influence on the sound quality. For the acoustical engineer it becomes important to know what kind of tools are available to measure, to analyse and to describe sound quality on the one hand and how to improve it on the other hand.

Photochemistry in Terrestrial Exoplanet Atmospheres III: Photochemistry and Thermochemistry in Thick Atmospheres on Super Earths and Mini Neptunes  

E-Print Network (OSTI)

Some super Earths and mini Neptunes will likely have thick atmospheres that are not H2-dominated. We have developed a photochemistry-thermochemistry kinetic-transport model for exploring the compositions of thick atmospheres on super Earths and mini Neptunes, applicable for both H2-dominated atmospheres and non-H2-dominated atmospheres. Using this model to study thick atmospheres for wide ranges of temperatures and elemental abundances, we classify them into hydrogen-rich atmospheres, water-rich atmospheres, oxygen-rich atmospheres, and hydrocarbon-rich atmospheres. We find that carbon has to be in the form of CO2 rather than CH4 or CO in a H2-depleted water-dominated thick atmosphere, and that the preferred loss of light elements from an oxygen-poor carbon-rich atmosphere leads to formation of unsaturated hydrocarbons (C2H2 and C2H4). We apply our self-consistent atmosphere models to compute spectra and diagnostic features for known transiting low-mass exoplanets GJ 1214 b, HD 97658 b, and 55 Cnc e. For GJ 1...

Air handler sound power prediction method based on ARI Standard 260  

Science Journals Connector (OSTI)

A method of predicting air handler sound power based on ratings for a product line is described. The method provides octave band sound power levels based on ratings obtained using Air?Conditioning and Refrigeration Institute (ARI) Standard 260 Sound Rating Of Ducted Air Moving And Conditioning Equipment. Detailed sound power information for HVAC equipment is not always available but it is important in accurately predicting noise levels in acoustically sensitive spaces. To address this need a rating program was undertaken using ARI 260. This standard is a reverberant room technique for sound rating ducted air conditioning equipment using a reference sound source substitution method. Since sound travels from the source to receiver along numerous paths this standard differentiates between sound power emanating from several common paths called components. Components for this project included ducted discharge free inlet plus casing ducted inlet and casing. The standard provides guidance on adequate number of fan sizes appurtenances and operating characteristics. The intent of the project was to provide a model to predict sound power by unit size component operating condition and unit configuration. Good agreement was found between predicted levels and measured data.

Dispersal of measured sound power levels for wind turbines  

Science Journals Connector (OSTI)

The standard IEC 61400?11 provides guidance in the measurement analysis and reporting of acoustic emissions(sound power levels) from wind turbine generator systems. The application of this standard aims to provide accurate results that can be replicated by others. We did several measurement operations according to this standard on various wind farms fitted with many turbine manufacturers on different ground types. Important differences have been noticed with equal working conditions between the most and the less noisy wind turbine on a single farm. We will present these results compared to the manufacturers' guaranteed values and initiate explanations (like the difficulties to link the wind speed at 10m above ground with the wind speed received at hub height; or the influence of wind incidence on blades).

In 1980 a 27?ft recreational vehicle was adapted to carry interactive science displays to local schools and community groups. This Mobile Science Museum (MSM) exhibits as many as 40 individual hands?on displays both inside as well as on tables directly outside the vehicle. University science students serve as docents and pass on their enthusiasm for science while providing role models for young visitors. Most displays are borrowed from university science teaching and research laboratories while others are developed and fabricated by faculty staff and students. Topics found to be particularly effective for presentation in the hands?on mode include sound light and marine biology. Far more schools request visits by the MSM than can be served within current budgetary constraints. While this project is supported by CSULB School of Natural Sciences the majority of the operating budget comes from other sources of funding including companies specializing in science and technology school districts parent/teacher associations and private individuals.

To that end composite configurations of acrylic polycarbonate aerogel and glass were tested in a laboratory and an acrylic room and glass vestibule were tested in the field. Results will be presented with an eye toward future use of the data. Indeed it was the unavailability of the data in existing publications that initially drove the research.

Pressure dependence of sound attenuation in the Pacific Ocean  

Science Journals Connector (OSTI)

Measurements of the attenuation of sound at a nominal frequency of 75 kHz have been made over vertical and horizontal acoustic paths located between depths of 700 and 3400 m in the Pacific Ocean. Results indicate that the equation used to predict attenuation overestimates the values actually encountered at these frequencies and depths. (Compare calculated values of 27.3 and 22.7 dB/km to measured values of 19.9±0.5 and 13.3±0.5 dB/km at depths of 910 and 3350 m respectively.) The measurements definitely establish the decrease of attenuation with increasing pressure. However the magnitude of the pressure coefficient of attenuation is almost twice as large as previously suspected (12.3±1.1×10?4/bar or approximately 12.3×10?4/atm compared to 6.54×10?4/atm).

On the Radiation of Sound from an Unflanged Circular Pipe  

Science Journals Connector (OSTI)

A rigorous and explicit solution is obtained for the problem of sound radiation from an unflanged circular pipe, assuming axially symmetric excitation. The solution is valid throughout the wave-length range of dominant mode (plane wave) propagation in the pipe. The reflection coefficient for the velocity potential within the pipe and the power-gain function, embodying the characteristics of the radiation pattern, are evaluated numerically. The absorption cross section of the pipe for a plane wave incident from external space, and the gain function for this direction, are found to satisfy a reciprocity relation. In particular, the absorption cross section for normal incidence is just the area of the mouth. At low frequencies of vibration, the velocity potential within the pipe is the same as if the pipe were lengthened by a certain fraction of the radius and the open end behaved as a loop. The exact value of the end correction turns out to be 0.6133.

Effects of CP Violation from Neutral Heavy Fermions on Neutrino Oscillations, and the LSND/MiniBooNE Anomalies  

E-Print Network (OSTI)

Neutrinos may mix with ultralight fermions, which gives flavor oscillations, and with heavier fermions, which yields short distance flavor change. I consider the case where both effects are present. I show that in the limit where a single oscillation length is experimentally accessible, the effects of heavier fermions on neutrino oscillations can generically be accounted for by a simple formula containing four parameters, including observable CP violation. I consider the anomalous LSND and MiniBooNE results, and show that these can be fit in a model with CP violation and two additional sterile neutrinos, one in the mass range between 0.1 and 20 eV, and the other with mass between 33 eV and 40 GeV. I also show that this model can avoid conflict with constraints from existing null short baseline experimental results.

Study of the catalyst deactivation in an industrial gasoil HDS reactor using a mini-scale laboratory reactor  

Science Journals Connector (OSTI)

The activity of a hydrodesulphurization catalyst loaded in an industrial hydrotreater is studied at start up and end of run. Catalyst initial and final activity was determined by performing HDS experiments at industrial conditions in a laboratory mini-scale hydrotreater. The results show that the deactivation of the catalyst samples collected from three different places of the industrial reactor do not vary significantly, the maximum difference among the catalyst samples, being less than ±4%. The experimentally determined deactivation level of the catalyst samples is compared with the deactivation estimated for the same industrial reactor and the same load using a hybrid neural network model trained with operational data of the industrial and the results are in close agreement. Catalyst deactivation appears to be faster for hydrogen consumption reactions than for hydrodesulphurization reactions indicating a decreasing hydrogen consumption trend with time in operation for specific sulphur content in the product.

Economic evaluation of small-scale photovoltaic hybrid systems for mini-grid applications in far north Cameroon  

Science Journals Connector (OSTI)

A comparison between photovoltaic hybrid systems (PVHS), standalone photovoltaic (PV) and standalone diesel generator options is performed using the net present value (NPV) technique. A typical village mini-grid energy demand of 7.08 kWh/day is considered in the computation of energy costs and breakeven grid distances. A first sensitivity analysis is conducted using remote diesel prices of 0.8 €/l, 0.98 €/l, 1.12 €/l, 1.28 €/l with a PV module cost of 7.5 €/Wp. A second sensitivity analysis is also done using PV module costs of 5.25 €/Wp, 6 €/Wp, 6.75 €/Wp, 7.5 €/Wp with a diesel price of 1.12 €/l. The energy cost for the diesel option was found to be 0.812 €/kWh at a diesel fuel price of 1.12 €/l. The sensitivity analyses showed that minimum energy costs were attained in PVHS at renewable energy fractions in the range 82.6–95.3%. In the second sensitivity analysis the energy costs and breakeven grid distances were found to be in the ranges 0.692–0.785 €/kWh and 5.1–5.9 km respectively. For a PV module cost of 5.25 €/Wp, the lowest energy cost for the PVHS option was 0.692 €/kWh at a final renewable energy fraction of 95.3% with the diesel generator hours being 37 h compared to 2075 h in the standalone diesel generator option. Consequently, a 30% reduction in custom duties and taxes on imported PV modules and sub-systems would increase the use of small-scale and climate friendly PV mini-grids in remote areas of far north Cameroon that have an annual insolation of at least 5.55 kWh/m2/day.

Structural-borne sound mitigation in small wind turbines using constrained viscoelastic layer  

Science Journals Connector (OSTI)

As the growing acceptance of small wind turbines operating in suburban and rural communities coincides with increasingly stringent regulations on the sound emitted by these turbines the need for sound mitigation solutions becomes urgent. Small turbines need to be affordable for small business use and thus proposed solutions must be cost-effective and low maintenance. Easy retrofit to existing turbines is also desirable. Wind turbines generate sound via two main mechanisms: structural borne sound generated by the gearbox and generator and transmitted through the nacelle structure and aeroacoustic sound generated by the interaction of the airstream with the rotating blades and other turbine components. Current study focused on the mitigation of structural-borne sound in a 50 kW wind turbine using a constrained viscoelastic layer. The viscoelastic layer comprised of multiple tiles with normal force to the nacelle structure provided by ratcheting bands. Optimal value for the normal force was empirically determined and the resulting reductions in generated sound were documented both in the laboratory and on a working turbine under a number of operating conditions. The result is a cost-effective solution with zero cost of ownership and easy installation on a wide range of small to medium-size wind turbines.

Auralization of urban soundscaping designs using the Arup SoundLab  

Science Journals Connector (OSTI)

Noise is unwanted sound (from an urban planning point of view). The standard practice to controlnoise while valuable is a negative process (i.e. reducing unwanted “noise”). In response there is a drive by several authorities to take a more positive approach to improve and manage soundscapes in cities and civic spaces. Urban soundscape design consists of planning shaping and managing the sound to fit each area of the masterplan in terms of civic cultural and social character. Arup uses its SoundLab a 3D sound facility (ambisonic) to design and auralise (the sound equivalent to visualisation) soundscapes with planners architects or artists and demonstrate to Local Planning Authorities or clients the results of the design. An example of urban soundscaping design is Dark Neville Street Leeds for Leeds City Council where architectural lighting design acoustical soundscaping design were integrated together with an artistic sonic piece by Hans?Peter Kuhn which was auralised in the Arup SoundLab. An example of “indoor” sonic art and soundscape design installation is “Harmonic Bridge” by Bill Fontana and Arup Acoustics in the Turbine Hall of the Tate Modern (June?August 2006) where the sonic art piece was composed in the SoundLab.

Puget Sound Dissolved Oxygen Modeling Study: Development of an Intermediate-Scale Hydrodynamic Model  

SciTech Connect

The Washington State Department of Ecology contracted with Pacific Northwest National Laboratory to develop an intermediate-scale hydrodynamic and water quality model to study dissolved oxygen and nutrient dynamics in Puget Sound and to help define potential Puget Sound-wide nutrient management strategies and decisions. Specifically, the project is expected to help determine 1) if current and potential future nitrogen loadings from point and non-point sources are significantly impairing water quality at a large scale and 2) what level of nutrient reductions are necessary to reduce or dominate human impacts to dissolved oxygen levels in the sensitive areas. In this study, an intermediate-scale hydrodynamic model of Puget Sound was developed to simulate the hydrodynamics of Puget Sound and the Northwest Straits for the year 2006. The model was constructed using the unstructured Finite Volume Coastal Ocean Model. The overall model grid resolution within Puget Sound in its present configuration is about 880 m. The model was driven by tides, river inflows, and meteorological forcing (wind and net heat flux) and simulated tidal circulations, temperature, and salinity distributions in Puget Sound. The model was validated against observed data of water surface elevation, velocity, temperature, and salinity at various stations within the study domain. Model validation indicated that the model simulates tidal elevations and currents in Puget Sound well and reproduces the general patterns of the temperature and salinity distributions.

Sound insulation property of Al-Si closed-cell aluminum foam bare board material  

Science Journals Connector (OSTI)

A1-Si closed-cell aluminum foam bare boards of 1?240 mm×1?100 mm with different densities and thicknesses were prepared by molten body transitional foaming process. The sound reduction index(R) of AI-Si closed-cell aluminum foam bare boards was investigated experimentally under different frequencies (100-4?000 Hz). It is found that sound reduction index(R) is small under low frequencies, large under high frequencies and is controlled by different mechanisms. The sound insulation property basically conforms with the monolayer board sound insulation theory. The sound reduction index(R) increases with the even growth of thickness and density, but its rising trend is tempered. The single number sound reduction indexes(Rw) of specimen with thickness of 20 cm and density of 0.51 g/cm3 are 30.8 dB and 33 dB respectively, which demonstrates good sound insulation property for lightmass materials.

Propagation of sound waves through a spatially homogeneous but smoothly time-dependent medium  

SciTech Connect

The propagation of sound through a spatially homogeneous but non-stationary medium is investigated within the framework of fluid dynamics. For a non-vortical fluid, especially, a generalized wave equation is derived for the (scalar) potential of the fluid velocity distribution in dependence of the equilibrium mass density of the fluid and the sound wave velocity. A solution of this equation for a finite transition period ? is determined in terms of the hypergeometric function for a phenomenologically realistic, sigmoidal change of the mass density and sound wave velocity. Using this solution, it is shown that the energy flux of the sound wave is not conserved but increases always for the propagation through a non-stationary medium, independent of whether the equilibrium mass density is increased or decreased. It is found, moreover, that this amplification of the transmitted wave arises from an energy exchange with the medium and that its flux is equal to the (total) flux of the incident and the reflected wave. An interpretation of the reflected wave as a propagation of sound backward in time is given in close analogy to Feynman and Stueckelberg for the propagation of anti-particles. The reflection and transmission coefficients of sound propagating through a non-stationary medium is analyzed in more detail for hypersonic waves with transition periods ? between 15 and 200 ps as well as the transformation of infrasound waves in non-stationary oceans. -- Highlights: •Analytically exact study of sound propagation through a non-stationary medium. •Energy exchange between the non-stationary medium and the sound wave. •Transformation of hypersonic and ultrasound frequencies in non-stationary media. •Propagation of sound backward in time in close analogy to anti-particles. •Prediction of tsunamis both in spatially and temporally inhomogeneous oceans.

Propagation of Transient Sound Signals into a Viscous Fluid  

Science Journals Connector (OSTI)

An arbitrary excitation of the plane x = 0 sends sound signals into the half?space x ? 0 occupied by the viscous fluid. The governing third?order partial differential equation is solved exactly using the Laplace transform on time and the sine transform on space. New expressions for the most general solution are derived. The specific inputs considered in detail are the Dirac delta function the Heaviside unit function a decaying exponential and a sinusoidal excitation. The final expressions are given in the form of real integrals and of exact power series. Short?time approximations are also given for a general input and for the four aforementioned specific inputs. Previously obtained approximations for the case of small attenuation coefficients are corrected and extended for the decaying exponential and the sinusoidal input. The results found indicate that viscosity tends to reduce the sharpness of the propagating disturbance and thus to smooth out any initially imposed discontinuity. The presence of the disturbance is felt immediately everywhere in the medium and in fact the short?time approximations satisfy the parabolic heat equation.

Processing of Prosthetic Heart Valve Sounds from Anechoic Tank Measurements  

SciTech Connect

People with serious cardiac problems have had their life span extended with the development of the prosthetic heart valve. However, the valves operate continuously at approximately 39 million cycles per year and are therefore subject to structural failures either by faulty design or material fatigue. The development of a non-invasive technique using an acoustic contact microphone and sophisticated signal processing techniques has been proposed and demonstrated on limited data sets. In this paper we discuss an extension of the techniques to perform the heart valve tests in an anechoic like. Here the objective is to extract a ''pure'' sound or equivalently the acoustical vibration response of the prosthetic valves in a quiet environment. The goal is to demonstrate that there clearly exist differences between values which have a specific mechanical defect known as single leg separation (SLS) and non-defective valves known as intact (INT). We discuss the signal processing and results of anechoic acoustic measurements on 50 prosthetic valves in the tank. Finally, we show the results of the individual runs for each valve, point out any of the meaningful features that could be used to distinguish the SLS from INT and summarize the experiments.

Sound propagation over Dickins Seamount in the Northeast Pacific Ocean  

Science Journals Connector (OSTI)

The acoustic propagation losses between a 230?Hz cw source and a multi?hydrophone receiving system were measured over Dickins Seamount in the Northeast Pacific. The source was towed at depths of 18 and 184 m. The receiving system had hydrophones spaced in depth from 323 to 633 m. The measurements were made to a maximum range of 130 km with the receiver located at a range of 60 km from the seamount peak. The results show that the seamount cast an acoustic shadow over the receiver increasing the propagation loss by up to 15 dB when the source was shallow and in a position which enabled the seamount to intercept all of the deep refracted source energy. Back reflections from the seamount with levels 6 to 13 dB below the direct signal level were present when the shallow source was 3 to 5 km from the seamount peak. Downslope reflections enhanced the direct signal by up to 10 dB when the shallow source was within 3 km of the peak. Acoustic shadowing and reflection effects were minimal in the results for the deep source because most of the source energy propagated along the sound?channel axis above the seamount peak. The analysis indicates that ray theory is adequate for describing the reflection effects of the acoustic propagation but does not account for all of the acoustic energy in the shadow zone.

The Velocity of Sound in an Absorptive Gas  

Science Journals Connector (OSTI)

The theory of velocity propagation in a gas as conditioned by internal energy exchanges is considered in detail for the simplest case in which the "lags" may be different—namely, the model with three sets of states. This "second order" theory is required for the interpretation of experimental results where the wave period is of the order of the lag for some states. Assuming the first vibration state of CO2 to have the largest lag in accordance with Kneser's interpretation of his recent experiments, the necessary approximations are given explicitly and the results are directly applicable to CO2. The apparent lag as measured in sound velocity experiments is not the simple stationary state mean "collision life" nor the mean life of the energy quantum except under special conditions and then for only one of the states. The velocity increment in the "resonance" region is given more accurately in terms of transition probabilities and is not described completely by the specific heats as might be expected from the "first order" theory. Contrary to the indications of the simple theory with an empirical constant the external energy is always merely the translation term. The status of the assumed lag assignment in CO2 is discussed in the light of the results and underlying theory of this paper.

Health-risk assessment of chemical contamination in Puget Sound seafood. Final report 1985-1988  

SciTech Connect

This report provides resource management and health agencies with a general indication of the magnitude of potential human health risks associated with consumption of recreationally harvested seafoods from Puget Sound. Data collection and evaluation focused on a variety of metal and organic contaminants in fish, shellfish and edible seaweeds from 22 locations in the Sound. EPA risk assessment techniques were used to characterize risks to average and high consumer groups for both carcinogens and noncarcinogens.

Possibility of Sound Propagation in Vacuums with the Speed of Light  

E-Print Network (OSTI)

An important question of theoretical physics is whether sound is able to propagate in vacuums at all and if this is the case, then it must lead to the reinterpretation of one zero-restmass particle which corresponds to vacuum-sound waves. Taking the electron-neutrino as the corresponding particle, its observed non-vanishing rest-energy may only appear for neutrino-propagation inside material media. The idea may also influence the physics of dense matter, restricting the maximum speed of sound, both in vacuums and in matter to the speed of light.

Radio sounding in space: magnetosphere and topside ionosphere  

Science Journals Connector (OSTI)

Modern sounding techniques have been developed for the space-borne exploration of Earth's magnetosphere and topside ionosphere. Two new satellite instruments will use the advanced techniques of the ground-based Digisondes. The Radio Plasma Imager (RPI), a low-frequency sounder with 500-m dipole antennas designed to sweep from 3 kHz to 3 MHz, will be part of NASA's IMAGE mission to be launched in February 2000 into an elliptical orbit with an altitude at apogee of 7Re. While in the magnetospheric cavity, RPI will receive echoes from the magnetopause and the plasmasphere and will measure the direct response of the magnetosphere's configuration to changes in the solar wind. With three orthogonal dipole antennas (two 500-m tip-to-tip antennas in the spin plane used for transmission and reception, one 20-m antenna along the spin axis for reception only) the arrival angle of returning echoes can be determined with high accuracy. The other instrument is the \\{TOPside\\} Automated Sounder (TOPAS), which was originally conceived for the Ukrainian WARNING mission with a launch date in 2001. Using one antenna for transmission and three orthogonal 10-m antennas for reception, TOPAS will be able to determine the arrival angle of ionospheric echoes and their wave polarization. It will then be possible to automatically scale the topside ionograms and calculate the electron density profiles in real time. Operating as a high-frequency radar, TOPAS will for the first time measure topside plasma velocities by tracking the motions of plasma irregularities.

Inter?laboratory variation in sound power levels in qualified reverberant rooms.  

Science Journals Connector (OSTI)

Reverberant acoustic test facilities can be qualified to determine the sound power levels of broadband and tonal noise sources using the procedures defined in Air?Conditioning Heating and Refrigeration Institute (AHRI) Std. 220 “Sound Power Testing Using Reverberant Rooms for HVAC Equipment.” Member companies from AHRI’s Technical Committee on Sound participated in a round robin test program in which tonal noise sources were shipped to and tested in a number of qualified reverberant rooms. This report summarizes the results of this effort. The mean and standard deviations of the sound power levels for multiple locations/orientations of the noise sources in each facility and for all facilities are presented. The standard deviations as a function of frequency for these sources were found to be generally less than the values established for broadband sources and therefore less than those allowed for tonal sources. Based on the comparisons of round robin test results accurate determinations of sound power levels can be made using the substitution method in rooms qualified in accordance with AHRI Std. 220 Technical Committee on Sound Air?Conditioning Heating and Refrigeration Institute

Untangling the roles of wind, run-off and tides in Prince William Sound  

Science Journals Connector (OSTI)

Prince William Sound (PWS) oceanic circulation is driven by a combination of local wind, large run-off and strong tides. Using a regional oceanic model of the Gulf of Alaska, adequately resolving the mean circulation and mesoscale eddies, we configure a series of three nested domains. The inner domain zooms in on Prince William Sound with a 1-km horizontal grid resolution. We analyze a set of four experiments with different combinations of run-off, wind and tides to demonstrate the relative influence of these forcing on the central Sound mean circulation cell and its seasonal variability. The mean circulation in the central PWS region is generally characterized by a cyclonic cell. When forced only by the wind, the circulation is cyclonic in winter and fall and strongly anticyclonic in summer. The addition of freshwater run-off greatly enhances the eddy kinetic energy in PWS partly through near-surface baroclinic instabilities. This leads to a much more intermittent circulation in the central Sound, with the presence of intense small-scale turbulence and a disappearance of the summer wind-forced anticyclonic cell. The addition of tides reduces the turbulence intensity (relatively to the experiment with run-off only), particularly in the central Sound. The generation of turbulent motions by baroclinic processes is lowered by tidal mixing and by modification of the exchange at Hinchinbrook Entrance. Tides have an overall stabilizing effect on the central Sound circulation. Tidal rectification currents help maintain a mean cyclonic circulation throughout the year.

Sound insulation property of Al–Si closed-cell aluminum foam sandwich panels  

Science Journals Connector (OSTI)

Al–Si closed-cell aluminum foam sandwich panels (1240 mm × 1100 mm) of different thicknesses and different densities were prepared by molten body transitional foaming process in Northeastern University. The experiments were carried out to investigate the sound insulation property of Al–Si closed-cell aluminum foam sandwich panels of different thicknesses and different densities under different frequencies (100–4000 Hz). Results show that sound reduction index (R) is small under low frequencies, large under high frequencies; thickness affects the sound insulation property of material obviously: when the thicknesses of Al–Si closed-cell aluminum foam sandwich panels are 12, 22, and 32 mm, the corresponding weighted sound reduction indices (RW) are 26.3, 32.2, and 34.6 dB, respectively, the rising trend tempered; the increase of density of Al–Si closed-cell aluminum foam can also increase the sound insulation property: when the densities of aluminum foam are 0.31, 0.51, and 0.67 g/cm3, the corresponding weighted sound reduction indices (RW) are 28.9, 34.3, and 34.6 dB, the increasing value mitigating.

The modeling and calculation of sound radiation from facilities with gas flowed pipes  

Science Journals Connector (OSTI)

Computer modeling of industrial facilities like chemical plants refineries or other production areas is the first and most important step in the calculation of sound exposure in the environment. The pipework with gas flows is often contributing relevant to the sound radiation of the complete facility. This radiation can be determined applying the methods described in technical papers like VDI 3733 and ISO 15664. On the basis of these descriptions a software tool was developed that allows to create pipework in 3D models with line sources and to calculate the sound propagation with methods like ISO 9613-2. The line sources are linked with the technical parameters like pipe cross section flow rate pressure density and temperature of the gas and material parameters of the pipe wall. The sound power emission from the pipe to the environment and the internal flow of sound power—linked to the next section of piping—is calculated on the basis of these parameters. The same technique is used to calculate the sound emission of cooling towers electric and fuel driven motors gears pumps and other devices. This powerful technique allows creating sustainable models that can be adapted to different operation conditions with minimum time and effort.

Pressure drop of two-phase plug flow in round mini-channels: Influence of surface wettability  

SciTech Connect

In the present experimental study, the pressure drop of two-phase plug flows in round mini-channels was investigated for three different tube materials, i.e., glass, polyurethane and Teflon, respectively, with their inner diameters ranging from 1.62 to 2.16 mm. Air and water were used as the test fluids. In the wet-plug flow regime (wet wall condition at the gas portions), the pressure drop was reasonably predicted by the homogeneous flow model or by the correlations of Mishima and Hibiki [K. Mishima, T. Hibiki, Some characteristics of air-water two-phase flow in small diameter vertical tubes, Int. J. Multiphase Flow 22 (1996) 703-712] and Chisholm [D. Chisholm, A theoretical basis for the Lockhart-Martinelli correlation for two-phase flow, Int. J. Heat Mass Transfer 10 (1967) 1767-1778]. On the other hand, in the dry-plug flow regime (dry wall condition at the gas portions), the role of the moving contact lines turned out to be significant. To take into account the effect of the moving contact lines, a modified Lockhart-Martinelli type correlation was proposed, which fitted the measured pressure-drop data within the mean deviation of 6%.

Reaction of plaice (Pleuronectes platessa) and cod (Gadus morhua) to low?frequency sound in an experimental tank  

Science Journals Connector (OSTI)

Anthropogenic sound in the sea is an increasing problem and more knowledge on the influence of sound on fish needs to be collected. For this reason experiments are carried out in an experimental tank 10 m in diameter to examine the reaction of juvenile and adult cod and plaice to sound. Pure tones from the frequency range of offshore wind turbines are artificially emitted in typical wind turbinesound levels of 130 and 140 dB re 1 Pa. A sound gradient in the tank enables the fish to avoid highest sound levels. The number of fish in the vicinity of the sound source is determined in regular time intervals before during and after the 24?h period of sound exposure. Changes in numbers of fish can be seen in the periods with and without sound in many experiments. Reactions of plaice are ambiguous pointing to both avoidance of or attraction to the sound. In the majority of the experiments carried out on cod avoidance behavior to the sound can be seen with strongest reactions at 25 60 and 90 Hz. The results indicate potential avoidance behavior of cod to the operational noise of offshore wind farms.

Classification of heart valve sounds from experiments in an anechoic water tank  

SciTech Connect

In vivo studies in both sheep and humans were plagued by a number of problems including movement artifacts, biological noise, low signal-to-noise ratio (SNR), chest-wall reverberation, and limited bandwidth recordings as discussed by [1]. To overcome these problems it was decided to record heart valve sounds under controlled conditions deep in an anechoic water tank, free from reverberation noise. The main goal of this experiment was to obtain measurements of ''pure'' heart valve sounds free of the scattering effects of the body. Experiments were conducted at the Transdec facility in San Diego [2]. We used a high quality hydrophone together with a wide-band data acquisition system [2]. We recorded sounds from 100 repetitions of the opening-closing cycles on each of 50 different heart valves, including 21 SLS valves and 29 intact valves. The power spectrum of the opening and closing phases of each cycle were calculated and outlier spectra removed as described by Candy [2]. In this report, we discuss the results of our classification of the heart valve sound measurements. The goal of this classification task was to apply the fundamental classification algorithms developed for the clinical data in 1994 and 1996 to the measurements from the anechoic water tank. From the beginning of this project, LLNL's responsibility has been to process and classify the heart valve sounds. For this experiment, however, we processed both the opening sounds and closing sounds for comparison purposes. The results of this experiment show that the classifier did not perform well because of low signal-to-noise ratio and excessive variability in signal power from beat-to-beat for a given valve.

Puget Sound Dissolved Oxygen Modeling Study: Development of an Intermediate Scale Water Quality Model  

SciTech Connect

The Salish Sea, including Puget Sound, is a large estuarine system bounded by over seven thousand miles of complex shorelines, consists of several subbasins and many large inlets with distinct properties of their own. Pacific Ocean water enters Puget Sound through the Strait of Juan de Fuca at depth over the Admiralty Inlet sill. Ocean water mixed with freshwater discharges from runoff, rivers, and wastewater outfalls exits Puget Sound through the brackish surface outflow layer. Nutrient pollution is considered one of the largest threats to Puget Sound. There is considerable interest in understanding the effect of nutrient loads on the water quality and ecological health of Puget Sound in particular and the Salish Sea as a whole. The Washington State Department of Ecology (Ecology) contracted with Pacific Northwest National Laboratory (PNNL) to develop a coupled hydrodynamic and water quality model. The water quality model simulates algae growth, dissolved oxygen, (DO) and nutrient dynamics in Puget Sound to inform potential Puget Sound-wide nutrient management strategies. Specifically, the project is expected to help determine 1) if current and potential future nitrogen loadings from point and non-point sources are significantly impairing water quality at a large scale and 2) what level of nutrient reductions are necessary to reduce or control human impacts to DO levels in the sensitive areas. The project did not include any additional data collection but instead relied on currently available information. This report describes model development effort conducted during the period 2009 to 2012 under a U.S. Environmental Protection Agency (EPA) cooperative agreement with PNNL, Ecology, and the University of Washington awarded under the National Estuary Program

Recording and Calculating Gunshot Sound—Change of the Volume in Reference to the Distance  

Science Journals Connector (OSTI)

An experiment was conducted in an open practice ground (shooting range) regarding the recording of the sound of gunshots. Shots were fired using various types of firearms (seven pistols five revolvers two submachine guns one rifle and one shotgun) in different calibers from several various distances with reference to the recording sources. Both a conventional sound level meter (device) and a measurement microphone were used having been placed in a fixed point behind the shooting line. The sound of each shot was recorded (from the device). At the same time the signal received by the microphone was transferred to a connected computer through an appropriate audio interface with a pre?amplifier. Each sound wave was stored and depicted as a wave function. After the physic?mathematical analysis of these depictions the volume was calculated in the accepted engineering units(Decibels or dB) of Sound Pressure Level (SPL). The distances from the recording sources were 9.60 meters 14.40 m 19.20 m and 38.40 m. The experiment was carried out by using the following calibers: .22 LR 6.35 mm(.25 AUTO) 7.62 mm Tokarev (7 62×25) 7.65 mm(.32 AUTO) 9 mm Parabellum (9×19) 9 mm Short (9×17) 9 mm Makarov (9×18) .45 AUTO .32 S&W .38 S&W .38 SPECIAL .357 Magnum 7 62 mm Kalashnikov (7 62×39) and 12 GA. Tables are given for the environmental conditions (temperature humidity altitude & barometric pressure) the length of the barrel of each gun technical characteristics of the used ammunition as well as for the volume taken from the SLM. The data for the sound intensity were collected after 168 gunshots (158 single shot & 10 bursts). According to the results a decreasing of the volume equivalent to the increasing of the distance was remarked as it was expected. Values seem to follow the Inverse square Law. For every doubling of the distance from the sound source the sound intensity diminishes by 5.9904±0.2325 decibels (on average). In addition we have the chance of determining the volume of the gunshot sound coming from a certain type of weapon. A further application could be the calculation of the distance from a shooting firearm if one is aware of a recorded volume.

As part of the AHRI ASA-ANSI and ISO standards development processes the uncertainty of sound power measurements needs to be quantified for inclusion in sound power standards. A study of four reverberation rooms with volumes of 140 280 560 and 1790 cubic meters was undertaken. Sound power levels for five noise sources (two vertical shafted sound sources two horizontal shafted sound sources and a leaf blower) were determined using ARI Standard 220. Variables investigated include: source location source orientation room conditions source operating characteristics and microphone traverse length. The frequency range of interest was 25 Hz to 10 kHz. Measurements were repeated and the order of tests was randomized. Of particular interest was the difference between the 140 cubic foot room and the other rooms to confirm the room qualification process required by ARI Standard 220 because the 140 cubic foot room does not meet the ARI Standard 220 qualification process but does meet the requirements in ISO 3741. This work will be helpful in understanding the sources of variation and allow for a starting point for determining if improvements are needed and if so what factors should be considered.

Effects of attenuation, dispersion, and high sound?pressure levels on acoustic wave distortion in horns  

Science Journals Connector (OSTI)

High?power sound sources have received a lot of attention in the past few years due to renewed interest in industrial applications of high?intensity sounds such as the acoustic agglomeration of aerosols or combustion enhancement. Most high?power sound sources require a horn to match the source impedance to the medium where the sound is radiated. Such horns introduce distortion in the initial waveform which can be detrimental to the agglomeration or combustion enhancement process. Boundary?layer attenuation smooths the wave shape while dispersion breaks up the symmetry of the waveform. Horn?induced dispersion is usually the dominant dispersion mechanism resulting in strong peaks in the waveform. Finally due to the very high acoustic levels at the horn throat finite?amplitude effects are responsible for a significant amount of distortion at high frequencies. Simple examples of waveform distortion due to these various mechanisms are shown. The effects of sound?pressure level horn design and frequency on distortion are illustrated for an exponential horn and several initial wave shapes. Experimental results are presented that compare very well with theory.

Development of a Hydrodynamic Model of Puget Sound and Northwest Straits  

SciTech Connect

The hydrodynamic model used in this study is the Finite Volume Coastal Ocean Model (FVCOM) developed by the University of Massachusetts at Dartmouth. The unstructured grid and finite volume framework, as well as the capability of wetting/drying simulation and baroclinic simulation, makes FVCOM a good fit to the modeling needs for nearshore restoration in Puget Sound. The model domain covers the entire Puget Sound, Strait of Juan de Fuca, San Juan Passages, and Georgia Strait at the United States-Canada Border. The model is driven by tide, freshwater discharge, and surface wind. Preliminary model validation was conducted for tides at various locations in the straits and Puget Sound using National Oceanic and Atmospheric Administration (NOAA) tide data. The hydrodynamic model was successfully linked to the NOAA oil spill model General NOAA Operational Modeling Environment model (GNOME) to predict particle trajectories at various locations in Puget Sound. Model results demonstrated that the Puget Sound GNOME model is a useful tool to obtain first-hand information for emergency response such as oil spill and fish migration pathways.

Anthropogenic sound—Introduction and overview of the ambient and anthropogenic environment  

Science Journals Connector (OSTI)

Interest in anthropogenic sound in the marine environment has been directed at concerns about the effects of sound on marine mammals. However fish make up a far larger and more diverse portion of the oceans than do marine mammals and they hold considerable economic importance internationally. This has led to a growing interest in the effect of anthropogenic sounds on fish in environments ranging from shallow waters near in?shore shipping lanes to the deep sea. Concerns for effects on fish are parallel to those for marine mammals and include issues ranging from the death of individual animals to the potential for behavioral changes that could lead to impacts on the survival of populations or species. While the body of data on the effects of anthropogenic sounds on fish is still small and much of the work is not in the peer?reviewed literature the number of peer?reviewed studies is growing. The purpose of this special session is to provide an overview of what we currently know about the effects of anthropogenic sound on fish help define the major outstanding questions on these effects and to provide the basis for discussion of current and future research in order to help resolve these questions.

Combining SRP-PHAT and two Kinects for 3D Sound Source Localization  

Science Journals Connector (OSTI)

Abstract The Kinect™ has been developed to recognize gestures and voice commands, through a set of cameras and microphones, respectively. This paper proposes and evaluates low-cost Sound Source Localization (SSL) solution based this off-the-shelf equipment. It consists of employing a pair of Kinect devices as an alternative for microphone array, and executing the Steered Response Power using the \\{PHAse\\} Transform (SRP-PHAT) localization algorithm over acquired sound data. A fully functional prototype has been implemented and put to test under a realistic scenario. Experimental results indicate that although our approach is capable of achieving limited position estimation, and it can accurately point towards the source’s direction. Two different high performance versions of the algorithm have been implemented to improve overall system performance under 3D Sound Source Localization setup.

Classification of heart valve sounds from experiments in an anechoic water tank  

SciTech Connect

In vivo studies in both sheep and humans were plagued by a number of problems including movement artifacts, biological noise, low signal-to-noise ratio (SNR), chest-wall reverberation, and limited bandwidth recordings as discussed by [1]. To overcome these problems it was decided to record heart valve sounds under controlled conditions deep in an anechoic water tank, free from reverberation noise, including surface reflections. Experiments were conducted in a deep water tank at the Transdec facility in San Diego, which satisfies these requirements. The Transdec measurements are free of reverberations, but not totally free of acoustic and electrical noise. We used a high quality hydrophone together with a wide-band data acquisition system [2]. We recorded sounds from 100 repetitions of the opening-closing cycles on each of 50 different heart valves, including 21 SLS valves and 29 intact valves. The power spectrum of the opening and closing phases of each cycle were calculated and outlier spectra removed as described by Candy [2]. In this report, we discuss the results of our classification of the heart valve sound measurements. The goal of this classification task was to apply the fundamental classification algorithms developed for the clinical data in 1994 and 1996 to the measurements from the anechoic water tank. From the beginning of this project, LLNL's responsibility has been to process and classify the heart valve opening sounds. For this experiment, however, we processed both the opening sounds and closing sounds for comparison purposes. The results of this experiment show that the classifier did not perform well. We believe this is because of low signal-to-noise ratio and excessive variability in signal power from beat-to-beat for a given valve.

Evaluation of hydro sound and vibration measurements during the use of the Hydro-Sound-Damper (HSD) at the wind farm “London Array”  

Science Journals Connector (OSTI)

Since some years a noise prevention concept for the protection of marine animals exists in Germany. Based on that the acoustic underwater noise from the pile driving at offshore wind farms is required to be less than 160 dB (SEL) at a distance of 750 m. This value however is often exceeded so that the use of a soundproofing system is necessary. The Hydro-Sound-Damper (HSD) is a new versatile method to reduce the noise during offshore pile driving. To achieve this elements of different sizes and materials are used which are fixed to fishing nets. The principle of operation and the effectiveness of these HSD elements were investigated in the laboratory and in situ under offshore conditions at the world’s largest offshore wind farm “London Array.” During the offshore tests thorough measurements were performed which metered the propagation of the hydro sound and the vibrations of the sea floor at various distances and directions. The evaluation of these data led to very promising results concerning underwater noise reduction. This article describes the theory and implementation of the HSD at “London Array” and focuses on the interpretation of the data from the hydro sound and vibration measurements.

Broadband low?frequency sound radiator with high?frequency pump resonator.  

Science Journals Connector (OSTI)

A new type of underwater low?frequency radiator is described. Operation of the radiator is based on the nonlinear conversion of high?frequency acoustic pump energy to low?frequency sound pulsation of the water volume of the open acoustic pump resonator. High?intensity pump waves in the resonator produce cavitation. Water containing bubbles is highly nonlinear (hundreds and even thousands of times more than pure water) and dispersive. Both of these factors and also the use of the pump resonator promote much stronger conversion of pump energy to low?frequency sound in comparison with a parametric radiator. The calculation of the acoustical characteristics is presented.

The role for low carbon electrification technologies in poverty reduction and climate change strategies: A focus on renewable energy mini-grids with case studies in Nepal, Peru and Kenya  

Science Journals Connector (OSTI)

As a potential poverty reduction and climate change strategy, this paper considers the advantages and disadvantages of using renewable energy technologies for rural electrification in developing countries. Although each case must be considered independently, given a reliable fuel source, renewable energy mini-grids powered by biomass gasifiers or micro-hydro plants appear to be the favoured option due to their lower levelised costs, provision of AC power, potential to provide a 24 h service and ability to host larger capacity systems that can power a wide range of electricity uses. Sustainability indicators are applied to three case studies in order to explore the extent to which sustainable welfare benefits can be created by renewable energy mini-grids. Policy work should focus on raising awareness about renewable energy mini-grids, improving institutional, technical and regulatory frameworks and developing innovative financing mechanisms to encourage private sector investments. Establishing joint technology and community engagement training centres should also be encouraged.

Variable Circular Collimator in Robotic Radiosurgery: A Time-Efficient Alternative to a Mini-Multileaf Collimator?  

SciTech Connect

Purpose: Compared with many small circular beams used in CyberKnife treatments, beam's eye view-shaped fields are generally more time-efficient for dose delivery. However, beam's eye view-shaping devices, such as a mini-multileaf collimator (mMLC), are not presently available for CyberKnife, although a variable-aperture collimator (Iris, 12 field diameters; 5-60 mm) is available. We investigated whether the Iris can mimic noncoplanar mMLC treatments using a limited set of principal beam orientations (nodes) to produce time-efficient treatment plans. Methods and Materials: The data from 10 lung cancer patients and the beam-orientation optimization algorithm 'Cycle' were used to generate stereotactic treatment plans (3 x 20 Gy) for a CyberKnife virtually equipped with a mMLC. Typically, 10-16 favorable beam orientations were selected from 117 available robot node positions using beam's eye view-shaped fields with uniform fluence. Second, intensity-modulated Iris plans were generated by inverse optimization of nonisocentric circular candidate beams targeted from the same nodes selected in the mMLC plans. The plans were evaluated using the mean lung dose, lung volume receiving {>=}20 Gy, conformality index, number of nodes, beams, and monitor units, and estimated treatment time. Results: The mMLC plans contained an average of 12 nodes and 11,690 monitor units. For a comparable mean lung dose, the Iris plans contained 12 nodes, 64 beams, and 21,990 monitor units. The estimated fraction duration was 12.2 min (range, 10.8-13.5) for the mMLC plans and 18.4 min (range, 12.9-28.5) for the Iris plans. In contrast to the mMLC plans, the treatment time for the Iris plans increased with an increasing target volume. The Iris plans were, on average, 40% longer than the corresponding mMLC plans for small targets (<80 cm{sup 3}) and {<=}121% longer for larger targets. For a comparable conformality index, similar results were obtained. Conclusion: For stereotactic lung irradiation, time-efficient and high-quality plans were obtained for robotic-controlled noncoplanar treatments using a mMLC. Iris is a time-efficient alternative for small targets, with similar or better plan quality.

Wind turbine sound prediction–The consequence of getting it wrong  

Science Journals Connector (OSTI)

The application to permit a wind turbine power development usually involves submission of a prediction for the sound level that will occur at residences schools places of worship and elsewhere people gather for restorative rest. This paper uses the example of a wind power development and follows iterations taken to finalize the sound level prediction. The paper provides quantitative information collected since the start up of the wind power development on measured sound levels and octave band distribution; and qualitative observations on the special characteristics of the sound. Actual observations are compared to the predictions. More importantly the paper reviews the consequences self-reported in qualitative interviews by citizens living with the changed environment after four years of operation of the wind power development. Reported impacts included difficulty sleeping loss of jobs and changes to social relationships caregiving pursuit of hobbies leisure learning and overall health. Changes in measured health outcomes are identified. Both the quantitative and qualitative findings justify revision of the permitting process.
