Cylindrical acoustic levitator/concentrator  

DOE Patents (OSTI)

A low-power, inexpensive acoustic apparatus for levitation and/or concentration of aerosols and small liquid/solid samples having particulates up to several millimeters in diameter in air or other fluids is described. It is constructed from a commercially available, hollow cylindrical piezoelectric crystal which has been modified to tune the resonance frequency of the breathing mode resonance of the crystal to that of the interior cavity of the cylinder. When the resonance frequency of the interior cylindrical cavity is matched to the breathing mode resonance of the cylindrical piezoelectric transducer, the acoustic efficiency for establishing a standing wave pattern in the cavity is high. The cylinder does not require accurate alignment of a resonant cavity. Water droplets having diameters greater than 1 mm have been levitated against the force of gravity using; less than 1 W of input electrical power. Concentration of aerosol particles in air is also demonstrated.

Simplified, low?cost, efficient, acoustic levitation system  

Science Journals Connector (OSTI)

Recently I have improved apparatus for the acoustic levitation of a drop of one liquid in another making it practical to build for anyone who has an oscillaior and audio amplifier with response to 50 kHz a current probe an inexpensive oscilloscope and a lead zirconate titanate cylinder of the right size. This piezoelectric cylinder (1.5?in. o.d. and length 0.125?in. thickness) is epoxied near the center of a foot long piece of standard 30?mm o.d. pyrex tube. A hollow piston with o?ring seal and O. 005?in. diaphragm acts as an excellent bottom pressure?release reflector of acoustic energy as is the top air—liquid interface leading to strong acoustic standing waves at particular resonance frequencies. Optimum frequencies are determined by observing the input current to the transducer as the oscillator is tuned between 47 and 55 kHz and as liquid and piston levels are adjusted. Benzene droplets in water have been levitated with only a fraction of a watt input to the transducer. More details of this simple system will be described. [Work supported by U. S.

Levitated Spinning Graphene  

E-Print Network (OSTI)

A method is described for levitating micron-sized few layer graphene flakes in a quadrupole ion trap. Starting from a liquid suspension containing graphene, charged flakes are injected into the trap using the electrospray ionization technique and are probed optically. At micro-torr pressures, torques from circularly polarized light cause the levitated particles to rotate at frequencies >1 MHz, which can be inferred from modulation of light scattering off the rotating flake when an electric field resonant with the rotation rate is applied. Possible applications of these techniques will be presented, both to fundamental measurements of the mechanical and electronic properties of graphene and to new approaches to graphene crystal growth, modification and manipulation.

Final Report: Levitated Dipole Experiment  

SciTech Connect

Since the very first experiments with the LDX, research progress was rapid and significant. Initial experiments were conducted with the high-field superconducting coil suspended by three thin rods. These experiments produced long-pulse, quasi-steady-state microwave discharges, lasting more than 10 s, having peak beta values of 20% [Garnier et al., Physics of Plasmas, 13 (2006) 056111]. High- beta, near steady-state discharges have been maintained in LDX for more than 20 seconds, and this capability made LDX the longest pulse fusion confinement experiment operating in the U.S. fusion program. A significant measure of progress in the LDX research program was the routine investigation of plasma confinement with a magnetically-levitated dipole and the resulting observations of confinement improvement. In both supported and levitated configurations, detailed measurements were made of discharge evolution, plasma dynamics and instability, and the roles of gas fueling, microwave power deposition profiles, and plasma boundary shape. High-temperature plasma was created by multi frequency electron cyclotron resonance heating at 2.45 GHz, 6.4 GHz, 10.5 GHz and 28 GHz allowing control of heating profiles. Depending upon neutral fueling rates, the LDX discharges contain a fraction of energetic electrons, with mean energies above 50 keV. Depending on whether or not the superconducting dipole was levitated or supported, the peak thermal electron temperature was estimated to exceed 500 eV and peak densities to approach 1e18 m?3. We have found that levitation causes a strong inwards density pinch [Boxer et al., Nature Physics, 6 (2010) 207] and we have observed the central plasma density increase dramatically indicating a significant improvement in the confinement of a thermal plasma species.

AB Levitator and Electricity Storage  

E-Print Network (OSTI)

The author researched this new idea - support of flight by any aerial vehicles at significant altitude solely by the magnetic field of the planet. It is shown that current technology allows humans to create a light propulsion (AB engine) which does not depend on air, water or ground terrain. Simultaniosly, this revolutionary thruster is a device for the storage of electricity which is extracted and is replenished (during braking) from/into the storage with 100 percent efficiency. The relative weight ratio of this engine is 0.01 - 0.1 (from thrust). For some types of AB engine (toroidal form) the thrust easily may be changed in any direction without turning of engine. The author computed many projects using different versions of offered AB engine: small device for levitation-flight of a human (including flight from Earth to Outer Space), fly VTOL car (track), big VTOL aircrat, suspended low altitude stationary satellite, powerful Space Shuttle-like booster for travel to the Moon and Mars without spending energ...

Magnetic levitation system for moving objects  

DOE Patents (OSTI)

Repelling magnetic forces are produced by the interaction of a flux-concentrated magnetic field (produced by permanent magnets or electromagnets) with an inductively loaded closed electric circuit. When one such element moves with respect to the other, a current is induced in the circuit. This current then interacts back on the field to produce a repelling force. These repelling magnetic forces are applied to magnetically levitate a moving object such as a train car. The power required to levitate a train of such cars is drawn from the motional energy of the train itself, and typically represents only a percent or two of the several megawatts of power required to overcome aerodynamic drag at high speeds. 7 figs.

This report describes theoretical and experimental investigations of a new approach to the problem of the magnetic levitation of a moving object. By contrast with previously studied levitation approaches, the Inductrack concept concept represents a simpler, potentially less expensive, and totally passive means of levitating a high-speed train. It may also be applicable to other areas where simpler magnetic levitation systems are needed, for example, high-speed test sleds for crash testing applications, or low-friction conveyer systems for industrial use.

Levitation: Is it Real? Levitation: Is it Real? « Back One hundred years ago, in 1911, a Dutchman by the name of Heike Kamerlingh Onnes discovered superconductivity. He found that mercury had no electrical resistance when cooled to 4.15 kelvins, or -451.93 degrees Fahrenheit. (Dry ice has a surface temperature of -109.3 ºF. Handling dry ice with your bare hand will give you frostbite!) Today, the race is on to find materials that are superconducting at room temperature. Once this happens, the world-wide web of electronics, power and transportation will be revolutionized. NSLS supports a rich program of research to understand the basic phenomenon of superconductivity and develop it in ways that will facilitate commercialization. Often, the work zigzags in unexpected ways. Over a decade ago, scientists

Processing of YBCO superconductors for improved levitation force  

SciTech Connect

One objective of the ANL superconductor program is to develop improved processing methods for production of YBCO superconductors with higher levitation forces suitable for low-friction, superconductor/permanent-magnet bearings and flywheel-energy-storage applications. From the standpoint of these applications, melt-processed bulk YBCO superconductors are of considerable interest. Levitation force and flux-pinning properties depend on microstructural features of the superconductors. We have added several chemical species to YBCO to alter the microstructure and have used a seeding technique to induce crystallization during melt processing. In this paper, we discuss the effects of various process parameters, additives, and a seeding technique on the properties of melt-processed bulk YBCO samples and compare the results with solid-state-sintered superconductors.

An expansion joint that allows a guideway of a magnetic levitation transportation system to expand and contract while minimizing transients occurring in the magnetic lift and drag forces acting on a magnetic levitation vehicle traveling over the joint includes an upper cut or recess extending downwardly from the upper surface of the guideway and a non-intersecting lower cut or recess that extends upwardly from the lower surface of the guideway. The side walls of the cuts can be parallel to each other and the vertical axis of the guideway; the depth of the lower cut can be greater than the depth of the upper cut; and the overall combined lengths of the cuts can be greater than the thickness of the guideway from the upper to lower surface so that the cuts will overlap, but be spaced apart from each other. The distance between the cuts can be determined on the basis of the force transients and the mechanical behavior of the guideway. A second pair of similarly configured upper and lower cuts may be disposed in the guideway; the expansion joint may consist of two upper cuts and one lower cut; or the cuts may have non-parallel, diverging side walls so that the cuts have a substantially dove-tail shape.

Architectural acoustics  

Science Journals Connector (OSTI)

This tutorial will familiarize people with basic concepts in architectural acoustics. Many slides of actual buildings and a brief audio tape will be used to illustrate connections between the visual appearance of buildings and the qualities of their sonic environment. The presentation will provide examples and explanations of common acoustic experiences in buildings with the under?lying reasons for their occurrence. Architectural acoustics can be characterized as an evolving empirical exploration of basic principles from many areas of acoustics through creative testing in the design and subsequent evaluation of buildings. A historical review of applied acoustical principles translated into the medium of architecture will be presented in four primary areas: (1) subjective impressions including qualities of music speech intelligibility and annoyance which are the basis for current design criteria; (2) room acoustics design with an emphasis on auditoria schools restaurants and other public buildings; (3) providing privacy from unwanted sounds and vibrations through discussion of standard measurement techniques such as sound transmission class (STC); and (4) management of noise from HVAC systems and other equipment and processes in buildings. Interesting case studies will demonstrate how complex the practical application of even relatively simple acoustical principles can be in many buildings. In recent years a significant community of laboratory and applied researchers dedicated to this field has emerged to question and quantify the empirical knowledge base that has been accumulated over time. Recent topics of interest such as new measurement modeling and simulation techniques will be briefly introduced.

Levitation pressure and friction losses in superconducting bearings  

DOE Patents (OSTI)

A superconducting bearing having at least one permanent magnet magnetized with a vertical polarization. The lower or stator portion of the bearing includes an array of high-temperature superconducting elements which are comprised of a plurality of annular rings. An annular ring is located below each permanent magnet and an annular ring is offset horizontally from at least one of the permanent magnets. The rings are composed of individual high-temperature superconducting elements located circumferentially along the ring. By constructing the horizontally-offset high-temperature superconducting ring so that the c-axis is oriented in a radial direction, a higher levitation force can be achieved. Such an orientation will also provide substantially lower rotational drag losses in the bearing.

Optical levitation of microdroplet containing a single quantum dot  

E-Print Network (OSTI)

Semiconductor nanocrystals, also known as quantum dots (QDs), are key ingredients in current quantum optics experiments. They serve as quantum emitters and memories and have tunable energy levels that depend not only on the material but also, through the quantum confinement effect, on the size. The resulting strongly confined electron and hole wave functions lead to large transition dipole moments, which opens a path to ultra strong coupling and even deep strong coupling between light and matter. Such efficient coupling requires the precise positioning of the QD in an optical cavity with a high quality factor and small mode volume, such as micro-Fabry--Perot cavity, whispering-gallery-mode microcavity, or photonic-crystal cavity. However, the absence of a technique for free-space positioning has limited the further research on QD-based cavity quantum electrodynamics. In this paper, we present a technique to overcome this challenge by demonstrating the optical levitation or trapping in helium gas of a single Q...

Parameters of a collisional radio-frequency sheath and dust characteristics resulting from the microparticle levitation  

SciTech Connect

The screening length, the time-average electric field, and the particle charge as well as the local vertical gradients of these quantities are determined experimentally within a sheath of a capacitively coupled rf, 13.56 MHz, discharge at enhanced argon gas pressures of 30, 55, and 100 Pa. The parameters are derived directly from comparative measurements of levitation positions of the particles of different sizes and variations in the levitation heights caused by formation of new dust layers. The electrostatic effect of the horizontally extended dust layers on the sheath electric field is investigated.

Acoustic cryocooler  

DOE Patents (OSTI)

An acoustic cryocooler with no moving parts is formed from a thermoacoustic driver (TAD) driving a pulse tube refrigerator (PTR) through a standing wave tube. Thermoacoustic elements in the TAD are spaced apart a distance effective to accommodate the increased thermal penetration length arising from the relatively low TAD operating frequency in the range of 15-60 Hz. At these low operating frequencies, a long tube is required to support the standing wave. The tube may be coiled to reduce the overall length of the cryocooler. One or two PTR's are located on the standing wave tube adjacent antinodes in the standing wave to be driven by the standing wave pressure oscillations. It is predicted that a heat input of 1000 W at 1000 K will maintian a cooling load of 5 W at 80 K.

Magnetic levitation systems for future aeronautics and space research and missions  

SciTech Connect

The objectives, advantages, and research needs for several applications of superconducting magnetic levitation to aerodynamics research, testing, and space-launch are discussed. Applications include very large-scale magnetic balance and suspension systems for high alpha testing, support interference-free testing of slender hypersonic propulsion/airframe integrated vehicles, and hypersonic maglev. Current practice and concepts are outlined as part of a unified effort in high magnetic fields R&D within NASA. Recent advances in the design and construction of the proposed ground-based Holloman test track (rocket sled) that uses magnetic levitation are presented. It is projected that ground speeds of up to Mach 8 to 11 at sea-level are possible with such a system. This capability may enable supersonic combustor tests as well as ramjet-to-scramjet transition simulation to be performed in clean air. Finally a novel space launch concept (Maglifter) which uses magnetic levitation and propulsion for a re-usable `first stage` and rocket or air-breathing combined-cycle propulsion for its second stage is discussed in detail. Performance of this concept is compared with conventional advanced launch systems and a preliminary concept for a subscale system demonstration is presented.

7 - Analog Video Processing  

Science Journals Connector (OSTI)

Abstract Only very small CCTV systems use the simple camera-monitor concept. Most of the bigger ones, in one way or another, use video switching or processing equipment before the signal is displayed on a monitor. With the introduction of digital video, all switching and processing, even of the analog video signals (certainly after they are digitized), are done over network and network switchers. This chapter may well be outdated within the next couple of years, but there are still existing analog CCTV systems out there, and therefore there was a need to still cover this topic.

Video image position determination  

DOE Patents (OSTI)

An optical beam position controller in which a video camera captures an image of the beam in its video frames, and conveys those images to a processing board which calculates the centroid coordinates for the image. The image coordinates are used by motor controllers and stepper motors to position the beam in a predetermined alignment. In one embodiment, system noise, used in conjunction with Bernoulli trials, yields higher resolution centroid coordinates.

THERMOHALINE INSTABILITIES INSIDE STARS: A SYNTHETIC STUDY INCLUDING EXTERNAL TURBULENCE AND RADIATIVE LEVITATION  

SciTech Connect

We have derived a new expression for the thermohaline mixing coefficient in stars, including the effects of radiative levitation and external turbulence, by solving Boussinesq equations in a nearly incompressible stratified fluid with a linear approximation. It is well known that radiative levitation of individual elements can lead to their accumulation in specific stellar layers. In some cases, it can induce important effects on the stellar structure. Here we confirm that this accumulation is moderated by thermohaline convection due to the resulting inverse {mu}-gradient. The new coefficient that we have derived shows that the effect of radiative accelerations on the thermohaline instability itself is small. This effect must however be checked in all computations. We also confirm that the presence of large horizontal turbulence can reduce or even suppress the thermohaline convection. These results are important as they concern all the cases of heavy element accumulation in stars. Computations of radiative diffusion must be revisited to include thermohaline convection and its consequences. It may be one of the basic reasons for the fact that the observed abundances are always smaller than those predicted by pure atomic diffusion. In any case, these processes have to compete with rotation-induced mixing, but this competition is more complex than previously thought due to their mutual interaction.

Acoustic cooling engine  

DOE Patents (OSTI)

An acoustic cooling engine with improved thermal performance and reduced internal losses comprises a compressible fluid contained in a resonant pressure vessel. The fluid has a substantial thermal expansion coefficient and is capable of supporting an acoustic standing wave. A thermodynamic element has first and second ends and is located in the resonant pressure vessel in thermal communication with the fluid. The thermal response of the thermodynamic element to the acoustic standing wave pumps heat from the second end to the first end. The thermodynamic element permits substantial flow of the fluid through the thermodynamic element. An acoustic driver cyclically drives the fluid with an acoustic standing wave. The driver is at a location of maximum acoustic impedance in the resonant pressure vessel and proximate the first end of the thermodynamic element. A hot heat exchanger is adjacent to and in thermal communication with the first end of the thermodynamic element. The hot heat exchanger conducts heat from the first end to portions of the resonant pressure vessel proximate the hot heat exchanger. The hot heat exchanger permits substantial flow of the fluid through the hot heat exchanger. The resonant pressure vessel can include a housing less than one quarter wavelength in length coupled to a reservoir. The housing can include a reduced diameter portion communicating with the reservoir. The frequency of the acoustic driver can be continuously controlled so as to maintain resonance.

History of engineering acoustics  

Science Journals Connector (OSTI)

At the Providence RI meeting in December 1955 it was proposed to add three new technical committees to the original seven established about a year earlier. Two of the new ones Audio Engineering and Electroacoustics and Sonic and Ultrasonic Engineering are precursors of the present Engineering Acoustics Technical Committee. In 1961 the name of the former committee was shortened to Electroacoustics and I began to attend their meetings. In 1964 the scope of the committee was broadened and its present name of Engineering Acoustics adopted. Early repeatable experiments in engineering acoustics have been attributed to Benjamin Franklin and mostly anecdotal evidence exists before that. Modern developments involve interdisciplinary involvements with all acoustics and specifically with the discovery of new materials applications of their properties and inventions of a wide variety of devices for producing receiving and using acoustics. Henry Joule Bell Berliner Edison the Curie brothers DeForest and Fessenden will be among those noted with some related recognition of them by the Engineering Acoustics TC.

Video Analytics for Indexing, Summarization and Searching of Video Archives  

SciTech Connect

This paper will be submitted to the proceedings The Eleventh IASTED International Conference on. Signal and Image Processing. Given a video or video archive how does one effectively and quickly summarize, classify, and search the information contained within the data? This paper addresses these issues by describing a process for the automated generation of a table-of-contents and keyword, topic-based index tables that can be used to catalogue, summarize, and search large amounts of video data. Having the ability to index and search the information contained within the videos, beyond just metadata tags, provides a mechanism to extract and identify "useful" content from image and video data.

Rigid levitation and suspension of high?temperature superconductors by magnets  

Science Journals Connector (OSTI)

A high?T c superconductor floating freely above a magnet of low symmetry remains rigidly suspended in the air in almost any position and orientation as if stuck in an invisible heap of sand. This striking effect is due to pinning of the magnetic flux lines inside the superconductor and is often overlooked since usually magnets with rotational symmetry are used for levitation. Magnets with rotational symmetry allow for nearly undamped orbiting and rotation of the superconductor about the magnet’s symmetry axis. But even in this geometry flux?line pinning can be seen since it forces the orbiting superconductor to turn the same face toward the axis. Superconductors with sufficiently strong pinning may even be suspended below a magnet.

Spacetime transformation acoustics  

E-Print Network (OSTI)

A recently proposed analogue transformation method has allowed the extension of transformation acoustics to general spacetime transformations. We analyze here in detail the differences between this new analogue transformation acoustics (ATA) method and the standard one (STA). We show explicitly that STA is not suitable for transformations that mix space and time. ATA takes as starting point the acoustic equation for the velocity potential, instead of that for the pressure as in STA. This velocity-potential equation by itself already allows for some transformations mixing space and time, but not all of them. We explicitly obtain the entire set of transformations that do not leave its form invariant. It is in these cases that ATA shows its true potential, allowing for building a transformation acoustics method that enables the full range of spacetime transformations. We provide an example of an important transformation which cannot be achieved with STA. Using this transformation, we design and simulate an acoustic frequency converter via the ATA approach. Furthermore, in those cases in which one can apply both the STA and ATA approaches, we study the different transformational properties of the corresponding physical quantities.

However, diver-based underwater visual censuses, and catch and effort data, remain the most commonly used for observing coastal biodiversity and species. In this paper, we review the underwater video techniques that have been developed since the 1950s to investigate and/or monitor coastal biodiversity. Techniques such as remote underwater video, whether baited or not, diver-operated video and towed video are described, along with corresponding applications in the field. We then analyse the complementary of techniques, first from studies comparing video techniques with other observation techniques, whether video-based or not, and second by documenting their respective cost efficiencies. These findings are discussed with respect to current challenges in monitoring and investigating coastal biodiversity. Video should be more often considered and used, either in addition to or as an alternative to diver-based, fishing and acoustic techniques, as it may be particularly suited for monitoring coastal biodiversity in a variety of areas and on larger scales than hitherto and within an ecosystem-based approach to management and conservation.

Acoustic paramagnetic logging tool  

DOE Patents (OSTI)

New methods and apparatus are disclosed which allow measurement of the presence of oil and water in geological formations using a new physical effect called the Acoustic Paramagnetic Logging Effect (APLE). The presence of petroleum in formation causes a slight increase in the earth's magnetic field in the vicinity of the reservoir. This is the phenomena of paramagnetism. Application of an acoustic source to a geological formation at the Larmor frequency of the nucleons present causes the paramagnetism of the formation to disappear. This results in a decrease in the earth3 s magnetic field in the vicinity of the oil bearing formation. Repetitively frequency sweeping the acoustic source through the Larmor frequency of the nucleons present (approx. 2 kHz) causes an amplitude modulation of the earth's magnetic field which is a consequence of the APLE. The amplitude modulation of the earth's magnetic field is measured with an induction coil gradiometer and provides a direct measure of the amount of oil and water in the excitation zone of the formation . The phase of the signal is used to infer the longitudinal relaxation times of the fluids present, which results in the ability in general to separate oil and water and to measure the viscosity of the oil present. Such measurements may be preformed in open boreholes and in cased well bores.

Modern Schoolroom Acoustics  

Science Journals Connector (OSTI)

Many teachers are faced with conducting classes in buildings that were obsolete thirty years ago. Others are or soon will be teaching in new schools which are in no way modern in some of their basic construction details. A classroom laboratory or auditorium is fundamentally a shelter in which the basic functions are seeing and hearing. Daylight provides satisfactory seeing a large part of the time. In spite of this about $1.50 per square foot is the average investment for auxiliary lighting while satisfactory acoustics is often completely overlooked or is the target of severe economy measures. Architects today are often eliminating or seriously compromising on the acoustical treatment expenditure while spending lavishly for less important materials. Eighty?five percent articulation will usually result in satisfactory hearing for adults because the context supplies the transitional ties. For children however especially the very young each word and every syllable is important. Excessive reverberation time or poor sound distribution may create conditions which seriously handicap the students and teachers alike. Modern medical methods have shown that poor eyes and poor hearing are often responsible for backward children who are really average or above average in mental ability. It is inexcusable to add to their natural handicaps those of poor architecture and poor engineering. Good acoustics is as fundamental as lighting and ventilation and much more attention should be paid to this phase of school design.

Axial and transverse acoustic radiation forces on a fluid sphere placed arbitrarily in Bessel beam standing wave tweezers  

SciTech Connect

The axial and transverse radiation forces on a fluid sphere placed arbitrarily in the acoustical field of Bessel beams of standing waves are evaluated. The three-dimensional components of the time-averaged force are expressed in terms of the beam-shape coefficients of the incident field and the scattering coefficients of the fluid sphere using a partial-wave expansion (PWE) method. Examples are chosen for which the standing wave field is composed of either a zero-order (non-vortex) Bessel beam, or a first-order Bessel vortex beam. It is shown here, that both transverse and axial forces can push or pull the fluid sphere to an equilibrium position depending on the chosen size parameter ka (where k is the wave-number and a the sphere’s radius). The corresponding results are of particular importance in biophysical applications for the design of lab-on-chip devices operating with Bessel beams standing wave tweezers. Moreover, potential investigations in acoustic levitation and related applications in particle rotation in a vortex beam may benefit from the results of this study. -- Highlights: •The axial and transverse forces on a fluid sphere in acoustical Bessel beams tweezers are evaluated. •The attraction or repulsion to an equilibrium position in the standing wave field is examined. •Potential applications are in particle manipulation using standing waves.

A highly modular beamline electrostatic levitation facility, optimized for in situ high-energy x-ray scattering studies of equilibrium and supercooled liquids  

SciTech Connect

High-energy x-ray diffraction studies of metallic liquids provide valuable information about structural evolution on the atomic length scale, leading to insights into the origin of the nucleation barrier and the processes of supercooling and glass formation. The containerless processing of the beamline electrostatic levitation (BESL) facility allows coordinated thermophysical and structural studies of equilibrium and supercooled liquids to be made in a contamination-free, high-vacuum ({approx}10{sup -8} Torr) environment. To date, the incorporation of electrostatic levitation facilities into synchrotron beamlines has been difficult due to the large footprint of the apparatus and the difficulties associated with its transportation and implementation. Here, we describe a modular levitation facility that is optimized for diffraction studies of high-temperature liquids at high-energy synchrotron beamlines. The modular approach used in the apparatus design allows it to be easily transported and quickly setup. Unlike most previous electrostatic levitation facilities, BESL can be operated by a single user instead of a user team.

Seismometer using a vertical long natural-period rotational pendulum with magnetic levitation  

SciTech Connect

We have demonstrated a highly sensitive/wideband vertical-component seismometer using an astatic rotational pendulum to obtain a long natural period. This seismometer employs magnetic levitation for removing any parasitic resonances of a spring to support a weight due to gravity and the thermal dependence of the spring constant. The pendulum has a cylindrical plunger-type permanent magnet that has a weight at one side of its end edge. The plunger magnet is inserted into a uniform magnetic field generated by a window-frame-type permanent magnet, and attached to two crossed-leaf spring hinges as a rotational axis outside of the bore of the magnet. Magnetic forces applied to the plunger magnet counterbalance the gravitational force at the weight. To realize stable operation of the rotational pendulum without any unnecessary movements of the plunger magnet, a tilt of lines of the magnetic force in the bore of the window-frame magnet was compensated by a tilted magnetic-pole surface near to its opening. The field uniformity reached 10{sup -4} owing to this compensation. The thermal dependence of a magnetic field strength of about 10{sup -3}/K was also compensated by as much as 9x10{sup -5}/K by Ni-Fe metal having a negative permeability coefficient. The metal was attached along the sidewalls of the window-frame magnet. To determine the feedback control parameters for a feedback control seismometer, the natural period of a prototype rotational pendulum was measured. It was more than 8 s, and was able to be changed from 5 to 8 s by using an additional magnetic spring, similar to the voice coil actuator of a speaker. This change was in accordance with theoretical calculations, and showed that the pendulum movement did not include a big nonlinearity caused by the tilt of the lines of the magnetic force. No parasitic resonances were found during experiments. A velocity feedback-control circuit and a capacitance position detector to measure the weight position were applied to the rotational pendulum for building a feedback control seismometer. Observations showed that the noise level of the seismometer was less than about 10{sup -8} m/s at 1 Hz. This fruitful value is close to the specifications of the most sensitive seismometer, such as STS-I. However, low-frequency noise of about 10{sup -7} m/s, caused by a buoyancy change at the pendulum weight arising from atmospheric pressure variation, could be recognized. To decrease the noise, a vacuum chamber to isolate the atmospheric pressure variation should be employed in the next step of the study.

Wireless technology and library acoustics  

Science Journals Connector (OSTI)

The modern library cannot function without modern technology. Printers copiers wireless computers and espresso machines all contribute to the soundscape of the typical municipal library (and many academic libraries too). While some of these noise sources are stationary and can be isolated acoustically wireless computing has transformed the acoustic experience for the typical library patron. Study carrels and desks used to define the boundaries of study and work areas in libraries and architects could design spaces accordingly. With wireless technology every space is a study space. This paper will discuss the implications of wireless technology on library acoustics. Measurement results at a variety of case study libraries will be presented.

Measurement of Acoustic Impedance  

Science Journals Connector (OSTI)

The acoustic impedance of a sample of material forming one boundary of a shallow cylindrical cavity can be determined by measuring the sound pressure produced when a known volume current is injected into the cavity from a high impedance source. The volume current is effectively determined by observing the pressure when the cavity is terminated rigidly. An impedance determination is thus reduced to measurement of the complex ratio of two observed voltages. By designing a ring source to suppress the first radial mode of the cavity the upper frequency limit set by uniformity of pressure distribution is extended by at least an octave. By avoiding leaks measurements can also be extended to very low frequencies. Secondary effects due to finite source impedance viscosity and heat losses at the walls have been evaluated. The method appears to be simple rapid and precise.

Acoustic detection of neutrinos  

Science Journals Connector (OSTI)

When high energy neutrinosinteract with nucleons in the ocean a jet of hadrons is produced which deposits thermal energy. This thermal energy is expected to produce a sonic pulse which hopefully will be sufficiently intense and directional to enable the energy and direction of incidence of the primary neutrino to be determined [Antares Parvulescu J. Acoust. Soc. Am. 61 580(A) (1977)]. This paper discusses the physical mechanism whereby the energy of the neutrino is converted into a sound pulse. A simple model will be exploited to account for the signature expected from such an event. [Work supported in part by the U. S. Naval Ocean Research and Development Activity and by the U. S.

Acoustically invisible cylinder  

Science Journals Connector (OSTI)

Coatings of new type recently proposed by the author (Acoustical Physics 2007 vol. 53 N5 pp. 535?545) are applied to bodies of cylindrical geometry to reduce reflection or scattering of sound and thus to make them undetectable by imaging systems. Such a coating called as a coating with extended reaction represents a periodic set of small elements with coupling between the neighboring elements. Appropriate choice of the coupling parameters makes its efficiency much higher than that of commonly used coatings. In the present paper it is shown by computer simulation that a rather simple coating of this type can reduce the back?scattered pressure amplitude more than 40 dB (with respect to the rigid cylinder) practically at all frequencies. Considerable reduction of the scattered power can also be achieved in a low frequency range. The width of this range and the reduction index depend on the number of couplings introduced into the coating.

Acoustic hemostasis: Underlying mechanisms  

Science Journals Connector (OSTI)

Cessation of hemorrhage using extrinsic interventional methods is possible with delivery of energy to bleeding tissues i.e. cauterization. High intensity focused ultrasound (HIFU) is one such method with significant advantages of delivering high levels of energy to well?defined regions of deep?seated tissues even during profuse bleeding. The physical mechanisms involved in this process include thermal and mechanical effects of HIFU leading to various biological effects. Our results using HIFU devices of 1–5 MHz and focal derated intensities of 1 000–10 000 W/cm2 in solid organs such as liver spleen and kidneys and major and minor blood vessels show that temperature of targeted tissues reaches 70–100°C within seconds with formation of microbubbles approximately 5??200 ? in size and concentration of 100 bubbles/mm3. It appears that boiling of interstitial fluids and blood and acoustic cavitation are both involved. The biological effects include coagulative necrosis mechanical disruption of tissue structure potentially leading to release of tissue factors enhancing the coagulation coagulum and thrombus formation at a wound site tissue fusion via collagen and elastin remodeling and fibrin plug formation with minimal damage of the surrounding tissues. These mechanisms appear to provide an effective and safe method of hemorrhage control. [Work supported by NIH DoD NSBRI.

Active acoustics systems are becoming more prevalent in architectural acoustics practice particularly in the context of repairing or improving acoustics in existing venues. Governmental policies to reduce funds and subsidies put into new facilities for the performing arts are another reason for designers to consider the use of active acoustics. This paper highlights two recent examples of such installations of ACS systems one at the Sydney Opera House Concert Hall and the other at MBCCH Winnepeg Canada. Collaboration between the system designer the musicians and the acoustics consultant will be emphasized along with techniques used to evaluate the systems' performance in the halls.

Creating coherent animations from video  

Science Journals Connector (OSTI)

In this paper, different techniques for the creation of time coherent figurative animations from a video input are presented. The animations are generated using an analysis-synthesis approach. Information of the scene is extracted using only a 2D RGB image. No markers or depth planes are needed. After the analysis, the image is drawn again using the extracted information. To guarantee temporal coherence when redrawing the image, different alternatives have been explored: matching and interpolation on the parameters domain and gradient descent parameter update. All methods and variations are described and illustrated with images.

Acoustic behavior of triple glazings  

Science Journals Connector (OSTI)

Making of triple glazings is the only way to still improve thermal performances of Insulating Glass Units. Possible ways with double glazings are already in use: increase the space between glasses use low emissivity coatings and special gas with lower thermal conductivity as argon or krypton. Specific acoustic weak point of double glazings is the resonance between the two panes which works as a mass spring mass system and coupling of eigenmodes of panes through the air (gas) cavity. These phenomena are of course still more important with triple glazings as there are two resonances. The paper will give all comparative data concerning thermal and acoustic performances and describe a way to achieve the same single number values of sound transmission loss with triple glazing that with double glazing by adding absorption in the gas cavities.

Video Games - Did They Begin at Brookhaven

Video Games – Did They Begin at Brookhaven? Video Games – Did They Begin at Brookhaven? Additional Web Pages The following account, written in 1981, tells how a Department of Energy research and development program led to the pioneering development of video games. William Higinbotham William Higinbotham First Pong, now Space Invaders, next Star Castle – video games have mesmerized children of at all ages across the country and around the world. Where did it all begin? Possibly at Brookhaven National Laboratory. In 1958, William Higinbotham, then head of BNL's Instrumentation Division, designed what may have been one of the first video games. Back then, Brookhaven had visitors days in the fall, and thousands of people came to tour the Lab and see exhibits set up in the gymnasium. Higinbotham's game was an illustration of what the Instrumentation Division could design and build.

More than fifty years ago, before either arcades or home video games, visitors waited in line at Brookhaven National Laboratory to play "Tennis for Two," an electronic tennis game that is unquestionably a forerunner of the modern video game. Tennis for Two was first introduced on October 18, 1958, at one of the Lab's annual visitors' days. Two people played the electronic tennis game with separate controllers that connected to an analog computer and used an oscilloscope for a screen. The game's creator, William

Frustrated total internal reflection acoustic field sensor  

DOE Patents (OSTI)

A frustrated total internal reflection acoustic field sensor which allows the acquisition of the acoustic field over an entire plane, all at once. The sensor finds use in acoustic holography and acoustic diffraction tomography. For example, the sensor may be produced by a transparent plate with transparent support members tall enough to support one or more flexible membranes at an appropriate height for frustrated total internal reflection to occur. An acoustic wave causes the membrane to deflect away from its quiescent position and thus changes the amount of light that tunnels through the gap formed by the support members and into the membrane, and so changes the amount of light reflected by the membrane. The sensor(s) is illuminated by a uniform tight field, and the reflection from the sensor yields acoustic wave amplitude and phase information which can be picked up electronically or otherwise.

Successfully merging architectural and electronic acoustical treatments  

Science Journals Connector (OSTI)

In enclosed volumes the integration of electronic acoustical components with architectural surface treatments forms a hybrid system that produces the perceived acoustical conditions. Since the underlying operating principles for electro-acoustic enhancement systems differs considerably between manufacturers the requirements for system infrastructure are not germane nor is the optimum integration of architectural treatments. As a result the nature of the work performed by the acoustical consultant changes to accommodate optimum performance of the specific “hybrid” system which may also include other forms of variable treatments.

Acoustic concentration of particles in fluid flow  

SciTech Connect

An apparatus for acoustic concentration of particles in a fluid flow includes a substantially acoustically transparent membrane and a vibration generator that define a fluid flow path therebetween. The fluid flow path is in fluid communication with a fluid source and a fluid outlet and the vibration generator is disposed adjacent the fluid flow path and is capable of producing an acoustic field in the fluid flow path. The acoustic field produces at least one pressure minima in the fluid flow path at a predetermined location within the fluid flow path and forces predetermined particles in the fluid flow path to the at least one pressure minima.

Acoustic resonance for nonmetallic mine detection  

SciTech Connect

The feasibility of acoustic resonance for detection of plastic mines was investigated by researchers at the Oak Ridge National Laboratory`s Instrumentation and Controls Division under an internally funded program. The data reported in this paper suggest that acoustic resonance is not a practical method for mine detection. Representative small plastic anti-personnel mines were tested, and were found to not exhibit detectable acoustic resonances. Also, non-metal objects known to have strong acoustic resonances were tested with a variety of excitation techniques, and no practical non-contact method of exciting a consistently detectable resonance in a buried object was discovered. Some of the experimental data developed in this work may be useful to other researchers seeking a method to detect buried plastic mines. A number of excitation methods and their pitfalls are discussed. Excitation methods that were investigated include swept acoustic, chopped acoustic, wavelet acoustic, and mechanical shaking. Under very contrived conditions, a weak response that could be attributed to acoustic resonance was observed, but it does not appear to be practical as a mine detection feature. Transfer properties of soil were investigated. Impulse responses of several representative plastic mines were investigated. Acoustic leakage coupling, and its implications as a disruptive mechanism were investigated.

Video summarization via minimum sparse reconstruction  

Science Journals Connector (OSTI)

Abstract The rapid growth of video data demands both effective and efficient video summarization methods so that users are empowered to quickly browse and comprehend a large amount of video content. In this paper, we formulate the video summarization task with a novel minimum sparse reconstruction (MSR) problem. That is, the original video sequence can be best reconstructed with as few selected keyframes as possible. Different from the recently proposed convex relaxation based sparse dictionary selection method, our proposed method utilizes the true sparse constraint L0 norm, instead of the relaxed constraint L 2 , 1 norm, such that keyframes are directly selected as a sparse dictionary that can well reconstruct all the video frames. An on-line version is further developed owing to the real-time efficiency of the proposed MSR principle. In addition, a percentage of reconstruction (POR) criterion is proposed to intuitively guide users in obtaining a summary with an appropriate length. Experimental results on two benchmark datasets with various types of videos demonstrate that the proposed methods outperform the state of the art.

Acoustics of technology enabled collaborative learning environments.  

Science Journals Connector (OSTI)

Collaborative classrooms and workstations are increasingly common in higher education buildings. These spaces present unique acoustical challenges that force designers to rethink traditional concepts and solutions. In student?centered classrooms the lecturer is removed as the visual and acoustical center of attention. Instead students are seated in groups around technology enabled workstations often facing away from the lecturer and other students. Acoustical conditions must support small?group interaction classroom discussion and learning via multimedia content. Outside the classroom collaborative workstations vary greatly but typically facilitate small?group interaction around a multimedia display and/or work surface. To promote impromptu use by students these spaces are often open to highly public areas of learning commons classroom buildings and digital libraries. Traditional noise control solutions fail to isolate these spaces without compromising their spontaneous feel and function. Despite obvious acoustical challenges both space types will continue to proliferate and new acoustical solutions must be developed.

Video Production Tips Video Production Tips R.A. Nocera There are many elements that contribute to a good video. Much of the work is in pre- production: script, storyboard, props, location, rehearsal, editing. All of these should be refined and ready before production and not interfere with the shooting schedule. I suggest creating a shot schedule of which scenes you are going to film - if you're shooting some scenes indoors and some outdoors, arrange the script in terms of location. This will make production much more efficient. There are many books and online pages about video production for reference. This is the most important aspect of film: SOUND. If you have a brilliant script, good actors, and direction, it will not translate if the sound is inaudible. Here are some ways

Video performance for high security applications.  

SciTech Connect

The complexity of physical protection systems has increased to address modern threats to national security and emerging commercial technologies. A key element of modern physical protection systems is the data presented to the human operator used for rapid determination of the cause of an alarm, whether false (e.g., caused by an animal, debris, etc.) or real (e.g., a human adversary). Alarm assessment, the human validation of a sensor alarm, primarily relies on imaging technologies and video systems. Developing measures of effectiveness (MOE) that drive the design or evaluation of a video system or technology becomes a challenge, given the subjectivity of the application (e.g., alarm assessment). Sandia National Laboratories has conducted empirical analysis using field test data and mathematical models such as binomial distribution and Johnson target transfer functions to develop MOEs for video system technologies. Depending on the technology, the task of the security operator and the distance to the target, the Probability of Assessment (PAs) can be determined as a function of a variety of conditions or assumptions. PAs used as an MOE allows the systems engineer to conduct trade studies, make informed design decisions, or evaluate new higher-risk technologies. This paper outlines general video system design trade-offs, discusses ways video can be used to increase system performance and lists MOEs for video systems used in subjective applications such as alarm assessment.

Writing magnetic patterns with surface acoustic waves  

SciTech Connect

A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive film with surface acoustic waves is demonstrated. Patterns of 10??m wide stripes of alternating magnetization and a 3??m dot of reversed magnetization are written using standing and focusing acoustic waves, respectively. The magnetization pattern is size-tunable, erasable, and rewritable by changing the magnetic field and acoustic power. This versatility, along with its solid-state implementation (no moving parts) and electronic control, renders it as a promising technique for application in magnetic recording, magnonic signal processing, magnetic particle manipulation, and spatial magneto-optical modulation.

Rehearsing for an audience: students learning science through video production  

Science Journals Connector (OSTI)

A study adapting the writing-to-learn in science model to include video production was conducted. Two Year 7 classes (N = 21, N = 22) in mixed ability and gender groups completed a science investigation. One class recorded their findings using a written text (posters) and the other produced videos. Quantitative results revealed greater learning gains for the video producers. Video data analysis indicated heightened awareness of audience for video producers and a subsequent tendency to rehearse before filming; both contributed to learning gains. Educational technological innovations such as in-class video production, combined with appropriate teacher pedagogy, can enhance students' science learning.

Surface acoustic wave dust deposition monitor  

DOE Patents (OSTI)

A system is disclosed for using the attenuation of surface acoustic waves to monitor real time dust deposition rates on surfaces. The system includes a signal generator, a tone-burst generator/amplifier connected to a transmitting transducer for converting electrical signals into acoustic waves. These waves are transmitted through a path defining means adjacent to a layer of dust and then, in turn, transmitted to a receiving transducer for changing the attenuated acoustic wave to electrical signals. The signals representing the attenuated acoustic waves may be amplified and used in a means for analyzing the output signals to produce an output indicative of the dust deposition rates and/or values of dust in the layer. 8 figs.

On observing acoustic backscattering from salinity turbulence  

Science Journals Connector (OSTI)

It has been hypothesized that at sufficiently high levels of oceanic salinity turbulence it should be possible to observe acoustic backscattering. However there have been limited in situmeasurements to confirm this hypothesis. Using an autonomous underwater vehicle equipped with upward and downward looking 1.2 MHz acoustic Doppler current profilers and with turbulence and fine scale sensors measurements were performed in a region of intense turbulence and a strong salinity gradient. The approach taken was to correlate variations in the backscattered acoustic intensity I with a theoretical acoustic backscattering cross section per volume for salinity turbulence ? s to obtain an estimated scattering cross section per volume ? e . Results indicated that of order 50% of the observed region was characterized by salinity turbulence induced backscattering.

Acoustic Energy Storage in Single Bubble Sonoluminescence  

E-Print Network (OSTI)

Single bubble sonoluminescence is understood in terms of a shock focusing towards the bubble center. We present a mechanism for significantly enhancing the effect of shock focusing, arising from the storage of energy in the acoustic modes of the gas. The modes with strongest coupling are not spherically symmetric. The storage of acoustic energy gives a framework for understanding how light intensities depend so strongly on ambient gases and liquids and suggests that the light intensities of successive flashes are highly correlated.

Parametric acoustic arrays: A Bergen view.  

Science Journals Connector (OSTI)

At the University of Bergen (UoB) Norway research activity in physical acoustics started in the mid?1960s with investigations on the parametric acoustic array (PAA). The newly appointed professor in applied mathematics Sigve Tjo/tta had some years earlier been at Brown University and was inspired by the concept at a fundamental level but also wanted experimental confirmation. No previous acoustical activity existed at UoB. The PAA project was started as a master project at Department of Physics where the main activity was in nuclear high?energy and ionospheric physics. Bellin and Beyer’s experiment served as a model. The results provided new information on the axial and directional properties of the difference frequency wave field. Inspired by this theoretical modeling continued along with further measurements. Other nonlinear effects like acoustic streaming (boundary layer density gradient) were also investigated. In 1975 a project together with SIMRAD and Norwegian Technical University resulted in a bottom penetrating PAA later commercialized as “TOPAS.” Numerical modeling based on the KZK equation resulted in the “Bergen Code ” still in use for computing nonlinear acoustic propagation problems. In later years activity at UoB has expanded to encompass linear physical acoustics of various sorts occasionally using PAA as a tool.

Tunable damper for an acoustic wave guide  

DOE Patents (OSTI)

A damper for tunably damping acoustic waves in an ultrasonic waveguide is provided which may be used in a hostile environment such as a nuclear reactor. The area of the waveguide, which may be a selected size metal rod in which acoustic waves are to be damped, is wrapped, or surrounded, by a mass of stainless steel wool. The wool wrapped portion is then sandwiched between tuning plates, which may also be stainless steel, by means of clamping screws which may be adjusted to change the clamping force of the sandwiched assembly along the waveguide section. The plates are preformed along their length in a sinusoidally bent pattern with a period approximately equal to the acoustic wavelength which is to be damped. The bent pattern of the opposing plates are in phase along their length relative to their sinusoidal patterns so that as the clamping screws are tightened a bending stress is applied to the waveguide at 180/sup 0/ intervals along the damping section to oppose the acoustic wave motions in the waveguide and provide good coupling of the wool to the guide. The damper is tuned by selectively tightening the clamping screws while monitoring the amplitude of the acoustic waves launched in the waveguide. It may be selectively tuned to damp particular acoustic wave modes (torsional or extensional, for example) and/or frequencies while allowing others to pass unattenuated.

Relationships between objective acoustic indices and acoustic comfort evaluation in nonacoustic spaces  

Science Journals Connector (OSTI)

Much attention has been paid to acoustic spaces such as concert halls and recording studios whereas research on nonacoustic buildings/spaces has been rather limited especially from the viewpoint of acoustic comfort. In this research a series of case studies has been carried out on this topic considering various spaces including shopping mall atrium spaces library reading rooms football stadia swimming spaces churches dining spaces as well as urban open public spaces. The studies focus on the relationships between objective acoustic indices such as sound pressure level and reverberation time and perceptions of acoustic comfort. The results show that the acoustic atmosphere is an important consideration in such spaces and the evaluation of acoustic comfort may vary considerably even if the objective acoustic indices are the same. It is suggested that current guidelines and technical regulations are insufficient in terms of acoustic design of these spaces and the relationships established from the case studies between objective and subjective aspects would be useful for developing further design guidelines.

Acoustics at University of Texas: History and current introductory course in physical acoustics.  

Science Journals Connector (OSTI)

As an academic discipline at the University of Texas acoustics began in the 1930s under C. Paul Boner in Physics and Lloyd A. Jeffress in Psychology. World War II saw Boner and many physicsgraduate students go to Harvard for “war work ” largely in underwater acoustics. When the war ended Boner returned and founded the Defense Research Laboratory later named Applied Research Laboratories. Interest in acoustics grew in Physics during the postwar years but eventually waned in the 1950s and 1960s. Acoustical activity developed in the 1960s in the College of Engineering chiefly Electrical Engineering and Mechanical Engineering. Today physical and engineering acoustics is a strong interdisciplinary program at Texas with faculty in several departments in Engineering and still a vestige in Physics. In addition much work on speech hearing and music is done in other parts of the University. Engineering features two basic courses in physical acoustics Acoustics I and II and five specialty courses which are described in an accompanying paper. Here we concentrate on Acoustics I and II which provide an introduction to propagation reflection and transmission refraction normal modes horn theory propagation in stratified fluids absorption and dispersion waveguides directional radiation diffraction and arrays.

Viscosity Effects in Acoustic Inductances  

Science Journals Connector (OSTI)

The linear acousticinductance and resistance of narrow circular tubes short compared to a wavelength have usually been represented by limiting formulas valid either for very low frequencies (viscous flow) or for relatively high frequencies (pistonlike displacement). Crandall's text gives a general mathematical development with particular stress on resistance but variation of inductance with frequency and viscosity has not been discussed generally nor has numerical reduction of mathematical results been generally available. The present paper describes quantitatively the dependence of inductance and resistance upon the general parameter radius times square root of the quantity density times frequency divided by viscosity. With increase of this parameter resistance increases while inductance diminishes from the “static” value to the limiting “high frequency” value. Experimental checks are made to ascertain whether resistance values are strongly affected by flow?transition end?effects found in hydraulics. Impedance?tube studies are made of five tube diameters from 0.0187 to 0.750 in. at 50 to 167 c/sec. Length/diameter is approximately 10 to render inductance end?corrections relatively small. Acoustic pressures are reduced until linear behavior appears. Measured resistance is generally within five percent of calculation as resistance increases to twice the “static” value. Measured inductance generally agrees with calculation within limits of the end?correction over the range of significant variation.

Method and apparatus of spectro-acoustically enhanced ultrasonic detection for diagnostics  

DOE Patents (OSTI)

An apparatus for detecting a discontinuity in a material includes a source of electromagnetic radiation has a wavelength and an intensity sufficient to induce an enhancement in contrast between a manifestation of an acoustic property in the material and of the acoustic property in the discontinuity, as compared to when the material is not irradiated by the electromagnetic radiation. An acoustic emitter directs acoustic waves to the discontinuity in the material. The acoustic waves have a sensitivity to the acoustic property. An acoustic receiver receives the acoustic waves generated by the acoustic emitter after the acoustic waves have interacted with the material and the discontinuity. The acoustic receiver also generates a signal representative of the acoustic waves received by the acoustic receiver. A processor, in communication with the acoustic receiver and responsive to the signal generated by the acoustic receiver, is programmed to generate informational output about the discontinuity based on the signal generated by the acoustic receiver.

P2P video-on-demand streaming using caching and reservation scheme based on video popularity  

Science Journals Connector (OSTI)

In peer-to-peer video-on-demand streaming, peers reduce video server load by caching viewed video data and sending these data to other peers. Although a first-in, first-out approach is typically used in the caching algorithm, it is not an efficient use of peers' upload capacity because the peers can cache the data of unpopular videos that no other peers request. In this paper, we propose a video-popularity-based caching and reservation (VPCR) scheme that increases the utilisation of peers' upload capacity. Through caching based on video popularity, even when peers view unpopular videos, they can deliver popular videos to other peers. The reservation scheme addresses temporal viewership fluctuations for each video which decrease utilisation of peers' upload capacity in VPCR. We evaluate VPCR through computer simulations and show that it is efficient in reducing the video server load under various video popularity distributions. We also show the relation between video server load and the number of simultaneous reservation acceptances for each peer.

Dual excitation acoustic paramagnetic logging tool  

DOE Patents (OSTI)

New methods and apparatus are disclosed which allow measurement of the presence of oil and water in geological formations using a new physical effect called the Acoustic Paramagnetic Logging Effect (APLE). The presence of petroleum in formation causes a slight increase in the earth's magnetic field in the vicinity of the reservoir. This is the phenomena of paramagnetism. Application of an acoustic source to a geological formation at the Larmor frequency of the nucleons present causes the paramagnetism of the formation to disappear. This results in a decrease in the earth's magnetic field in the vicinity of the oil bearing formation. Repetitively frequency sweeping the acoustic source through the Larmor frequency of the nucleons present (approx. 2 kHz) causes an amplitude modulation of the earth's magnetic field which is a consequence of the APLE. The amplitude modulation of the earth's magnetic field is measured with an induction coil gradiometer and provides a direct measure of the amount of oil and water in the excitation zone of the formation. The phase of the signal is used to infer the longitudinal relaxation times of the fluids present, which results in the ability in general to separate oil and water and to measure the viscosity of the oil present. Such measurements may be performed in open boreholes and in cased well bores. The Dual Excitation Acoustic Paramagnetic Logging Tool employing two acoustic sources is also described. 6 figs.

Acoustic demonstrations for education in speech science  

Science Journals Connector (OSTI)

Acoustic demonstrations are highly effective for education in speech science. We recently developed two educational tools for acoustics. The first educational tool is a set of physical models of the human vocal tract and related models. It contains cylinder and plate?type models [T. Arai J. Phonetic Soc. Jpn. 5(2) 31–38 (2001)] a sliding three?tube model [T. Arai Acoust. Sci. Technol. to be published] lungmodels an artificial larynx and head?shaped models [T. Arai Acoust. Sci. Technol. 27(2) 111–113 (2006)]. Each model has its own advantages and if combined effectively can produce a systematic and comprehensive education in speech production from the lungs to the head. The second educational tool is ‘‘Digital Pattern Playback (DPP)’’ [T. Arai et al. Acoust. Sci. Tech. to be published] which converts a spectrographic image of a speech signal back to sound by digital signal processing. A printed spectrogram on a sheet of paper can also be converted immediately after capturing the image from a camera and we confirmed that this is more intuitive for learners than converting from an electronic image.

History of American acoustics—Introductory comments  

Science Journals Connector (OSTI)

The history of acoustics has been illuminated by the efforts in recent years of R. Bruce Lindsay and so this Bicentennial Session is being held in his honor. In addition certain numerological factors spurred our efforts in this Bicentennial Year 1976. It was just one hundred years ago that A. G. Bell's invention—the first practical telephone—was exhibited at the 1876 Centennial Exposition in Philadelphia. A year later in 1877 the first edition of Rayleigh's Theory of Sound appeared. The conjunction of these two events eventually had a powerful influence on the development of acoustics. The invited speakers will in the papers which follow endeavor to describe all of the significant advances made by Americans to technical acoustics. Apparently it all began with Joseph Henry's efforts to solve a problem in auditorium acoustics. At the brink of World War II acoustics was invaded by a host of scientists and engineers. During the period 1941–45 and in the post war years frontiers were breached in almost every direction at such a rate that description of the advances made cannot be done here. And so most of our speakers will bring their histories up only to about the year 1940.

Developing criteria for identifying acoustical defects  

Science Journals Connector (OSTI)

In a construction defect lawsuit of a multifamily residential project the determination of whether a defect exists often hinges on the criteria applied. For many acoustical items such as plumbing and HVAC noise there are no code requirements but a number of guidelines and recommendations. For items such as noise from traffic or airborne and impact sound isolation between units minimum code requirements exist but often a more stringent standard is applied. How does an expert decide when it is appropriate to apply an acoustical standard that is beyond that required by building codes? Project drawings marketing materials homeowner regulations and other documents can provide indications of the intent and promise of the project as it relates to acoustical issues. The process is discussed with examples from recent cases.

Active micromixer using surface acoustic wave streaming  

DOE Patents (OSTI)

An active micromixer uses a surface acoustic wave, preferably a Rayleigh wave, propagating on a piezoelectric substrate to induce acoustic streaming in a fluid in a microfluidic channel. The surface acoustic wave can be generated by applying an RF excitation signal to at least one interdigital transducer on the piezoelectric substrate. The active micromixer can rapidly mix quiescent fluids or laminar streams in low Reynolds number flows. The active micromixer has no moving parts (other than the SAW transducer) and is, therefore, more reliable, less damaging to sensitive fluids, and less susceptible to fouling and channel clogging than other types of active and passive micromixers. The active micromixer is adaptable to a wide range of geometries, can be easily fabricated, and can be integrated in a microfluidic system, reducing dead volume. Finally, the active micromixer has on-demand on/off mixing capability and can be operated at low power.

A Video Integrated Measurement (VIM) System is described which incorporates the use of various noninvasive diagnostic procedures (moire contourography, electromyography, posturometry, infrared thermography, etc.), used individually or in combination, for the evaluation of neuromusculoskeletal and other disorders and their management with biofeedback and other therapeutic procedures. The system provides for measuring individual diagnostic and therapeutic modes, or multiple modes by split screen superimposition, of real time (actual) images of the patient and idealized (ideal-normal) models on a video monitor, along with analog and digital data, graphics, color, and other transduced symbolic information. It is concluded that this system provides an innovative and efficient method by which the therapist and patient can interact in biofeedback training/learning processes and holds considerable promise for more effective measurement and treatment of a wide variety of physical and behavioral disorders.

Acoustically enhanced remediation, Phase 2: Technology scaling  

SciTech Connect

Weiss Associates is conducting the following three phase program investigating the in-situ application of acoustically enhanced remediation (AER) of contaminated unconsolidated soil and ground water under both saturated and unsaturated conditions: Phase I-- laboratory scale parametric investigation; Phase II--technology Scaling; and Phase III--large scale field tests. AER addresses the need for NAPL (either lighter or denser than water: LNAPL or DNAPL, respectively) in high and low permeability sediments, and the remediation of other types of subsurface contaminants (e.g., metals, radionuclides) in low permeability soils. This program has been placed in the U.S. Department of Energy`s (DOE`s) DNAPL product. Phase I indicated that AER could be used to effectively remediate NAPL in high permeability soil, and that removal of NAPL from low permeability soil could be increased since the water flux through these soils was significantly increased. Phase II, Technology Scaling, the subject of this paper, focused on (1) evaluating the characteristics of an AER field deployment system, (2) developing DNAPL flow and transport performance data under acoustic excitation, (3) predicting the effect of acoustic remediation in three-dimensional unconsolidated hydrogeologic conditions, (4) conducting an engineering analysis of acoustical sources, and (5) identifying candidate field site(s) for large-scale field testing of the technology.

Acoustic-emission monitoring during hydraulic fracturing  

SciTech Connect

This paper reports that microseismic events or acoustic emissions associated with hydraulic fracturing are recorded with a borehole seismic tool in a deviated well during multirate injection, shut-in, and flowback. The event locations indicate that fracture orientation, length, and height are compatible with regional stress directions and estimates of the fracture size that are based on pressure decline.

Upgrading secret military facilities—What is more important, acoustic design standards or acoustical performance?  

Science Journals Connector (OSTI)

The U.S. Department of Defense has developed acoustical performance standards that are to be achieved in the design and construction of meeting and conference rooms where sensitive and secret information will be discussed. These performance standards rely on published acoustical industry design data which are readily available. The intention of these standards is to prevent sensitive and secret information from being heard understood or otherwise obtained by persons or devices that are not authorized to have access to such information. This paper presents design and field performance test results for new and renovated secret rooms that initially passed the acoustical design criteria and acoustical standard field tests but failed to provide the desired secret level acoustical performance. Further investigations and research into partition component and building composite performance indicated that floors walls ceilings doors windows and perimeter penetrations by conduit and HVAC ducting which individually met the design standards and when installed meet the design standards but as a composite did not provide the intended acoustical performance that would prevent unauthorized access to sensitive and secret information by persons or devices outside the designated perimeter. Reasons for certain performance failures are discussed and specific successful remedies are presented.

History of proposed Acoustical Society standard on “Underwater Passive Acoustic Monitoring for Bioacoustic Applications”.  

Science Journals Connector (OSTI)

In 2005 an ASA working group was formed to examine whether a standard should exist for “Passive Acoustic Monitoring for Marine Mammal Mitigation for Seismic Surveys”. Public discussions at subsequent meetings quickly showed that no consensus existed for specifying hardware requirements for passive acoustic measurements but consensus did seem possible for specifying “minimum requirements for recording and reporting bioacoustic data”. The proposed standard was renamed “Underwater Passive Acoustic Monitoring for Bioacoustic Applications” with three defined goals: (1) providing a set of requirements for information to be documented while recording acoustic data at sea (metadata requirements); (2) detailing the minimum information about acoustic hardware and software to be included when reporting results in gray or peer?reviewed literature; and (3) specifying metrics to be used when summarizing the features of an acoustic signal such as signal?to?noise ratio. A set of recommended best?practice procedures and equipment capabilities would also be included as an informative annex. After languishing for several years an attempt is being made to develop the standard further. This presentation describes the ASA standard outlines the development process and sketches the current thinking on the standard with an emphasis on the metrics portion.

Robust video authentication system over internet protocol  

Science Journals Connector (OSTI)

This paper presents a video authentication system over internet protocol that is insusceptible to illumination and expression variations. The illumination and expression invariant features are extracted using multi-band feature extraction. These features are classified by a radial basis function neural network. A new adaptive decision fusion method is proposed to combine the scores from different modalities and the different frames during the authentication process. Three levels of decision fusion are carried out in the proposed adaptive decision fusion. Depending on the level of decision fusion, the level of illumination influence is taken into account during the decision making.

Acoustic boundary layer and acoustic radiation from a ribbed flat plate  

Science Journals Connector (OSTI)

The acoustic boundary?layer theory(patterned after the viscous boundary?layer theory) is derived by noting that for low frequencies where the structural wavelength is much less than the fluid acoustic wavelength there is a region about the vibrating structure which behaves as if the fluid was incompressible. The dimension of this region depends upon the particular conditions of the problem. In a paper presented by the author [J. Acoust. Soc. Am. 62 S32(A) (1977)] the theory behind the acoustic boundary layer was developed and applied to simple unit problems. In this paper the near and the far field of a force driven plate is obtained by the use of the acoustic boundary?layer theory. Two different problems are addressed. In the first instance the structure is assumed to be homogeneous while in the second problem presented a rib is attached to the flat plate. In both instances the fully coupled fluid structure problem is solved and comparisons between the exact classical approach and the proposed theory are discussed.

Development of a geothermal acoustic borehole televiewer  

SciTech Connect

Most geothermal wells are drilled in hard rock formations where fluid flow is through systems of open fractures. Productivity of these wells is usually determined by the extent of intersection of the wellbore with the fracture system. A need exists for fracture mapping methods and tools which can operate in a geothermal environment. In less hostile environments, the acoustic borehole televiewer has been shown to be a useful tool for determining location, orientation, and characterization of fractures as they intersect the borehole and for general wellbore and casing inspection. The development conducted at Sandia National Laboratories to adapt an acoustic borehole televiewer for operation in a geothermal environment is described. The modified instrument has been successfully tested at temperatures as high as 280/sup 0/C and pressures up to 5000 psi, and used successfully to map fractures and casing damage in geothermal wells.

Acoustical performance testing of duct silencers  

Science Journals Connector (OSTI)

The test method used in North America to evaluate the acoustical performance of duct silencers is ASTM E477. The ASTM standard provides an approved method for measuring the aerodynamic pressure drop dynamic insertion loss and self?generated noise of duct silencers. Unfortunately restrictions on the construction of the test duct in the current standard cause erroneous results in the measurement of insertion loss at low frequencies. These errors are due to acoustic resonances that occur naturally in the empty test duct. It is recommended that the standard be modified to require anechoic terminations at both ends of the test duct. It is also recommended that more specific design criteria for the source chamber be established and that a new section be added to provide for the measurement of the radiated noise from the casing of the test specimen. Specific recommendations relating to all of these issues will be provided.

Broadband acoustic imaging of breaking waves  

Science Journals Connector (OSTI)

An acoustic array was deployed in the near?surface layer in Saanich Inlet BC to image breaking waves using only the naturally occurring acoustical radiation in the band (160 and 2000 Hz) from the breaking region. The 15?element array was configured as a horizontal cross with an 8?m aperture bottom?moored and positioned nominally 3 m beneath the surface. A novel broadband scheme combined information at six independent frequencies above about 400 Hz to yield unambiguous resolved images. A parametric image analysis shows that the images align closely with the wind and can be observed moving downwind with a speed roughly equal to the dominant phase speed of the wind waves. Absolute power levels are found to be consistent with previously published results. The data also provide inferences regarding the sound generation mechanism at ‘‘collective oscillation’’ frequencies below about 400 Hz. [Work supported by ONR.

Powerful, efficient, robust, electro?acoustic transducers  

Science Journals Connector (OSTI)

The STAR™ resonant reciprocating transducer began as a lightweight linear alternator design for a space?power free?piston Stirling engine in the early 1990's. It has since been developed into a range of commercially available motors and alternators with rated powers from 100 to over 10 000 watts (acoustic). As motors these are acoustic pressure drivers with unlimited operating life and typical transduction efficiencies of 80?90 percent. This paper explains the electrodynamics and operation of these moving? magnet Lorentz?force devices and the unique geometric configuration that has allowed scaling over such a wide range. We discuss the design and function of the unique single?degree?of?freedom flexure suspension that enables both the compact geometry and unlimited service life without wear. Data is presented from a large sample of units placed in service during the last decade demonstrating the durability and performance of these remarkable devices.

An overview of time?reversal acoustics  

Science Journals Connector (OSTI)

Time?reversal invariance is a very powerful concept in physics. In the field of acoustics where time reversal invariance occurs time?reversal experiments may be achieved simply with arrays of transmit?receive transducers allowing an incident wave field to be sampled recorded time?reversed and re?emitted. Time reversal mirrors (TRMs) may be used to study random media and chaotic reverberating structures. Common to these complex media is a remarkable robustness exemplified by observations that the more complex the medium between the probe source and the TRM the sharper the focus. TRMs open the way to new signal processings that interest imaging detection telecommunications and therapy. Time reversal mirrors have plenty of applications including ultrasonic therapy and medical imaging non destructive testing telecommunications underwater acoustics seismology sound control home automation. An overview of these fields will be presented.

NW-MILO Acoustic Data Collection  

SciTech Connect

There is an enduring requirement to improve our ability to detect potential threats and discriminate these from the legitimate commercial and recreational activity ongoing in the nearshore/littoral portion of the maritime domain. The Northwest Maritime Information and Littoral Operations (NW-MILO) Program at PNNL’s Coastal Security Institute in Sequim, Washington is establishing a methodology to detect and classify these threats - in part through developing a better understanding of acoustic signatures in a near-shore environment. The purpose of the acoustic data collection described here is to investigate the acoustic signatures of small vessels. The data is being recorded continuously, 24 hours a day, along with radar track data and imagery. The recording began in August 2008, and to date the data contains tens of thousands of signals from small vessels recorded in a variety of environmental conditions. The quantity and variety of this data collection, with the supporting imagery and radar track data, makes it particularly useful for the development of robust acoustic signature models and advanced algorithms for signal classification and information extraction. The underwater acoustic sensing system is part of a multi-modal sensing system that is operating near the mouth of Sequim Bay. Sequim Bay opens onto the Straight of Juan de Fuca, which contains part of the border between the U.S. and Canada. Table 1 lists the specific components used for the NW-MILO system. The acoustic sensor is a hydrophone permanently deployed at a mean depth of about 3 meters. In addition to a hydrophone, the other sensors in the system are a marine radar, an electro-optical (EO) camera and an infra-red (IR) camera. The radar is integrated with a vessel tracking system (VTS) that provides position, speed and heading information. The data from all the sensors is recorded and saved to a central server. The data has been validated in terms of its usability for characterizing the signatures of small vessels. The sampling rate of 8 kHz and low pass filtering to 2 kHz results in an alias-free signal in the frequency band that is appropriate for small vessels. Calibration was performed using a Lubell underwater speaker so that the raw data signal levels can be converted to sound pressure. Background noise is present due to a nearby pump and as a result of tidal currents. More study is needed to fully characterize the noise, but it does not pose an obstacle to using the acoustic data for the purposes of vessel detection and signature analysis. The detection range for a small vessel was estimated using the calibrated voltage response of the system and a cylindrical spreading model for transmission loss. The sound pressure of a typical vessel with an outboard motor was found to be around 140 dB mPa, and could theoretically be detected from 10 km away. In practical terms, a small vessel could reliably be detected from 3 - 5 km away. The data is archived in netCDF files, a standard scientific file format that is "self describing". This means that each data file contains the metadata - timestamps, units, origin, etc. - needed to make the data meaningful and portable. Other file formats, such as XML, are also supported. A visualization tool has been developed to view the acoustic data in the form of spectrograms, along with the coincident radar track data and camera images.

Ongoing developments in classroom acoustic theory and practice in 2012, and reports on efforts to implement good classroom acoustics  

Science Journals Connector (OSTI)

We live in a time of increasingly loud competing sounds and hearing loss is the number one disability in the world. Diverse populations of school children are especially vulnerable. The result is a degradation of the child’s academic achievement. New classrooms built everyday often incorporate acoustical barriers which limit students’ achievements. Overcoming these barriers involves funding constraints construction timelines and lack of support which requires advocacy from parents school boards and design teams. This advocacy should include the ANSI Classroom Acoustics standards and an acoustical assessment of existing classrooms. Complex classroom acoustics challenges may include reduction of noise radiated by HVAC systems improved acoustic treatment of external walls to minimize exterior noise and acoustic design of walls between adjacent noisy classrooms. Next steps for schools should be to retain an architect and/or an acoustical engineer for remodels and new school construction who are well versed in acoustics for educational settings and noise control. A booklet covering these issues and designed as a practical guide for educators not versed in acoustics is in preparation by the Acoustical Society of America.

Integration of video and radiation analysis data  

SciTech Connect

For the past several years, the integration of containment and surveillance (C/S) with nondestructive assay (NDA) sensors for monitoring the movement of nuclear material has focused on the hardware and communications protocols in the transmission network. Little progress has been made in methods to utilize the combined C/S and NDA data for safeguards and to reduce the inspector time spent in nuclear facilities. One of the fundamental problems in the integration of the combined data is that the two methods operate in different dimensions. The C/S video data is spatial in nature; whereas, the NDA sensors provide radiation levels versus time data. The authors have introduced a new method to integrate spatial (digital video) with time (radiation monitoring) information. This technology is based on pattern recognition by neural networks, provides significant capability to analyze complex data, and has the ability to learn and adapt to changing situations. This technique has the potential of significantly reducing the frequency of inspection visits to key facilities without a loss of safeguards effectiveness.

Acoustic enhancement for photo detecting devices  

DOE Patents (OSTI)

Provided are improvements to photo detecting devices and methods for enhancing the sensitivity of photo detecting devices. A photo detecting device generates an electronic signal in response to a received light pulse. An electro-mechanical acoustic resonator, electrically coupled to the photo detecting device, damps the electronic signal and increases the signal noise ratio (SNR) of the electronic signal. Increased photo detector standoff distances and sensitivities will result.

Acoustic measurement of potato cannon velocity  

E-Print Network (OSTI)

This article describes measurement of potato cannon velocity with a digitized microphone signal. A microphone is attached to the potato cannon muzzle and a potato is fired at an aluminum target about 10 m away. The potato's flight time can be determined from the acoustic waveform by subtracting the time in the barrel and time for sound to return from the target. The potato velocity is simply the flight distance divided by the flight time.

Acoustic radiation due to surface wave breaking.  

Science Journals Connector (OSTI)

While wave breaking is continually occurring at the sea surface its transient and sporadic nature makes it difficult to measure. Experimental results are presented that show how acoustic methods can be used as a remote sensor of this fundamental process. Sea surface?generated acoustic radiation (40 to 4000 Hz) is directly related to a quantitative measure of the boundary dynamics; i.e. the Toba variable. The frequency spectrum of the radiation remains remarkably unchanged over a wide range of environmental conditions but the correlation between the sound pressure level and the Toba variable undergoes an abrupt change when spilling breakers start to occur. Results support the use of acoustics to remotely measure the rate of energy being dissipated by wave breaking and the wavelength of the dominant gravity wave component. Theoretical studies have related the field measurements to analytical and laboratory results cited in the literature indicating that remote monitoring of the rate of occurrence and size distribution of ‘‘infant’’ (freshly entrained) bubbles may be possible if splashes on the surface do not radiate significant sound. Signal processing algorithms for the remote measurements discussed above are enhanced by eigenstructure analysis of the measured cross?spectral density matrix. [Work sponsored by ONR and NUSC.

Air transducers with high acoustic impedance  

Science Journals Connector (OSTI)

High?Z air transducers evolved from several industrial transducers. These predecessors include (a) acoustic emission and angle?beam NDT contact transducers; (b) flowmeter transducers for high?pressure methane hot refinery gases and corrosive flare gases; and (c) transducer arrays for monitoring hot corrosive gases flowing at Mach 0.1 in smokestacks of ?3–13 m. This peculiar ancestry accounts for their unusual high?acoustic?impedance construction. By not employing low?Z air?backed radiating membranes transducer bandwidth response time and sensitivity are sacrificed. The solid robust construction however offers some compensating features: tolerance to wide ranges in pressure and temperature including rapid rates of change (thermal shock depressurization); corrosion resistance; operable with standard lab equipment without bias voltage; mounting options where the transducer forms part of the pressure boundary or where it is outside the pressure boundary. Clamp?on air flow applications at one bar include small wind tunnels and plastic pipes. Acoustically isolated pairs measure secondary flow components (crossflow circulation) in a plane perpendicular to the pipe axis. Flow applications include gases such as air mild steam (pending) or other hot pressurized or corrosive fluids. Air?coupled measurements of transmission characteristics of wood or other low?density solids and air?ranging are readily demonstrated with the low?Z transducers.

Acoustical renovation of portable classrooms for cochlear implanted pupils  

Science Journals Connector (OSTI)

Anticipating increased enrollment of children with cochlear implants the Riverside County Office of Education undertook the acoustical renovation of two portable classrooms in California’s Riverside County: Wildomar Elementary School in Wildomar and Katherine Finchy Elementary School in Palm Springs. The aim was to improve the acoustical environment to make the classrooms suitable for pupils with severe hearing disabilities (reduce noise and reverberation). Lacking an acoustical standard specific for cochlear implanted pupils the acoustical goals chosen were those of the ANSI acoustical standard S12.60?2002. Key changes were intended to reduce interior noise from HVAC and improve the facade insulation to reduce exterior noise intrusion. The resulting acoustical improvements are documented. Costs and lessons learned are discussed.
