Using reference frames and the Global Positioning System (GPS) to produce control networks for spatial data  

E-Print Network (OSTI)

The Global Positioning System has enabled researchers to gather spatial data on a scale that was, until recently, cost prohibitive. Projects that cover an area of a few hectares can be included in data sets that cover entire countries. The ease at which point locations can be measured over large distances has highlighted an existing problem with data capture. Data collected using one set of control points may or may not overlay data collected using another. This thesis details a procedure for setting base control points that cover very large areas. Data obtained from the International GPS Service for Geodynamics (IGS) is used in conjunction with the International Terrestrial Reference Frame (ITRF) to establish control points anywhere in the world. Researchers utilizing these control points for base station locations or as registration points, are able to produce data with an absolute accuracy of 0.3 meter between projects, countries and continents. The problem of overlaying data has been reduced to the point that it is insignificant. Issues of datum and projections, and the use of existing data sets are addressed. Of special interest are the short project times and resulting cost savings over conventional methods. Specific projects in Texas, Azerbaijan, and Mali are presented. The project in Texas is the same size as the project in Azerbaijan, but on different continents. The project in Mali is much larger and has been the most comprehensive, from setting initial control points to training local researchers in data collection.

Determination of locational error associated with global positioning system (GPS) radio collars in relation to vegetation and topography in north-central New Mexico  

Science Conference Proceedings (OSTI)

In 1996, a study was initiated to assess seasonal habitat use and movement patterns of Rocky Mountain elk (Cervus elaphus nelsoni) using global positioning system (GPS) radio collars. As part of this study, the authors attempted to assess the accuracies of GPS (non-differentially corrected) positions under various vegetation canopies and terrain conditions with the use of a GPS ``test`` collar. The test collar was activated every twenty minutes to obtain a position location and continuously uplinked to Argos satellites to transfer position data files. They used a Telonics, Inc. uplink receiver to intercept the transmission and view the results of the collar in real time. They placed the collar on a stand equivalent to the neck height of an adult elk and then placed the stand within three different treatment categories: (1) topographical influence (canyon and mesa tops), (2) canopy influence (open and closed canopy), and (3) vegetation type influence (ponderosa pine and pinion pine-juniper). The collar was kept at each location for one hour (usually obtaining three fixes). In addition, the authors used a hand-held GPS to obtain a position of the test collar at the same time and location.

Management: Global positioning and wireless dispatching  

Science Conference Proceedings (OSTI)

Over the last several years, my company has been supplying many service companies with wireless dispatching solutions. Recently the impact of the system has been greatly increased with the introduction of a GPS (Global Position Systems) interface. This adds visual recognition as to the whereabouts of each vehicle within the customer service area. The only equipment required in the field for GPS is a transmit/receive device and a wireless modem, one mounted out of the way in the vehicle (under the seat) and a {open_quotes}hockey puck{close_quotes} size unit on the roof of the vehicle. The GPS received unit and wireless modem are used to retrieve the longitude, latitude and ground speed coordinates and transmit them back to the host system.

Global lightning and severe storm monitoring from GPS orbit  

Science Conference Proceedings (OSTI)

Over the last few decades, there has been a growing interest to develop and deploy an automated and continuously operating satellite-based global lightning mapper [e.g. Christian et al., 1989; Weber et al., 1998; Suszcynsky et al., 2000]. Lightning is a direct consequence of the electrification and breakdown processes that take place during the convective stages of thunderstorm development. Satellite-based lightning mappers are designed to exploit this relationship by using lightning detection as a proxy for remotely identifying, locating and characterizing strong convective activity on a global basis. Global lightning and convection mapping promises to provide users with (1) an enhanced global severe weather monitoring and early warning capability [e.g. Weber et al., 1998] (2) improved ability to optimize aviation flight paths around convective cells, particularly over oceanic and remote regions that are not sufficiently serviced by existing weather radar [e.g. Weber et al., 1998], and (3) access to regional and global proxy data sets that can be used for scientific studies and as input into meteorological forecast and global climatology models. The physical foundation for satellite-based remote sensing of convection by way of lightning detection is provided by the basic interplay between the electrical and convective states of a thundercloud. It is widely believed that convection is a driving mechanism behind the hydrometeor charging and transport that produces charge separation and lightning discharges within thunderclouds [e.g. see chapter 3 in MacGorman and Rust, 1998]. Although cloud electrification and discharge processes are a complex function of the convective dynamics and microphysics of the cloud, the fundamental relationship between convection and electrification is easy to observe. For example, studies have shown that the strength of the convective process within a thundercell can be loosely parameterized (with large variance) by the intensity of the electrical activity within that cell as measured by the lightning flash rate. Williams [2001] has provided a review of experimental work that shows correlations between the total lightning flash rate and the fifth power of the radar cloud-top height (i.e. convective strength) of individual thunder cells. More recently, Ushio et al., [2001] used a large statistical sampling of optical data from the Lightning Imaging Sensor (LIS) in conjunction with data provided by the Precipitation Radar (PR) aboard the Tropical Rainfall Monitoring Mission (TRMM) satellite to conclude that the total lightning flash rate increases exponentially with storm height. Lightning activity levels have also been correlated to cloud ice content, a basic product of the convective process. For example, Blyth et al. [2001] used the Thermal Microwave Imager (TMI) aboard the TRMM satellite to observe a decrease in the 37 and 85 GHz brightness temperatures of upwelling terrestrial radiation during increased lightning activity. This reduction in brightness temperature is believed to be the result of increased ice scattering in the mixed phase region of the cloud. Toracinta and Zipser [2001] have found similar relationships using the Optical Transient Detector (OTD) satellite instrument and the Special Sensor Microwave Imager (SSM/I) aboard the DMSP satellites.

GPS Spoofing Countermeasures Jon S. Warner, Ph.D. and Roger G. Johnston, Ph.D., CPP Vulnerability Assessment Team Los Alamos National Laboratory Los Alamos, New Mexico, 87545 Abstract: Civilian Global Positioning System (GPS) receivers are vulnerable to a number of different attacks such as blocking, jamming, and spoofing. The goal of such attacks is either to prevent a position lock (blocking and jamming), or to feed the receiver false information so that it computes an erroneous time or location (spoofing). GPS receivers are generally aware of when blocking or jamming is occurring because they have a loss of signal. Spoofing, however, is a

Evaluation of habitat use by Rocky Mountain elk (Cervus elaphus nelsoni) in north-central New Mexico using global positioning system radio collars  

SciTech Connect

In 1996 the authors initiated a study to identify habitat use in north-central New Mexico by Rocky Mountain elk (Cervus elaphus nelsoni) using global positioning system (GPS) radio collars. They collared six elk in the spring of 1996 with GPS radio collars programmed to obtain locational fixes every 23 h. Between April 1, 1996 and January 7, 1997, they collected >1,200 fixes with an approximately 70% observation rate. They have interfaced GPS locational fixes of elk and detailed vegetation maps using the geographical information system to provide seasonal habitat use within mountainous regions of north-central New Mexico. Based on habitat use and availability analysis, use of grass/shrub and pinon/juniper habitats was generally higher than expected during most seasons and use of forested habitats was lower than expected. Most of the collared elk remained on LANL property year-round. The authors believe the application of GPS collars to elk studies in north-central New Mexico to be a more efficient and effective method than the use of VHF (very-high frequency) radio collars.

The future of GPS-based electric power system measurements, operation and control  

Science Conference Proceedings (OSTI)

Much of modern society is powered by inexpensive and reliable electricity delivered by a complex and elaborate electric power network. Electrical utilities are currently using the Global Positioning System-NAVSTAR (GPS) timekeeping to improve the network`s reliability. Currently, GPS synchronizes the clocks on dynamic recorders and aids in post-mortem analysis of network disturbances. Two major projects have demonstrated the use of GPS-synchronized power system measurements. In 1992, the Electric Power Research Institute`s (EPRI) sponsored Phase Measurements Project used a commercially available Phasor Measurements Unit (PMU) to collect GPS-synchronized measurements for analyzing power system problems. In 1995, Bonneville Power Administration (BPA) and Western Area Power Administration (WAPA) under DOE`s and EPRI`s sponsorship launched the Wide Area Measurements (WAMS) project. WAMS demonstrated GPS-synchronized measurements over a large area of their power networks and demonstrated the networking of GPS-based measurement systems in BPA and WAPA. The phasor measurement technology has also been used to conduct dynamic power system tests. During these tests, a large dynamic resistor was inserted to simulate a small power system disturbance.

New Technique for Proposing Network's Topology using GPS and GIS  

E-Print Network (OSTI)

The problem of proposed topology for network comes when using Prim's algorithm with default distance (unrealistic distances) between network's nodes and don't care about the lakes, high hills, buildings, etc. This problem will cause incorrect estimations for cost (budget) of requirements like the media (optic fibre) and the number or type of Access-points, regenerator, Optic Amplifier, etc. This paper proposed a new technique of implementing Prim's algorithm to obtain realistic topology using realistic distances between network's nodes via Global Positioning System GPS and Geographic Information Systems GIS packages. Applying the new technique on academic institutes network of Erbil city from view of media (optic fibre) shows that there is disability in cost (budget) of the media which is needed (nearly) 4 times if implement default Prim's algorithm (don't using GPS & GIS) base on unrealistic distances between the nodes.

TAGGING, TRACKING AND LOCATING WITHOUT GPS  

SciTech Connect

The Savannah River National Laboratory (SRNL) was requested to lead a Law Enforcement Working Group that was formed to collaborate on common operational needs. All agencies represented on the working group ranked their need to tag, track, and locate a witting or unwitting target as their highest priority. Specifically, they were looking for technologies more robust than Global Positioning Satellite (GPS), could communicate back to the owner, and worked where normal cell phone communications did not work or were unreliable. SRNL brought together multiple technologies in a demonstration that was held in in various Alaska venues, including metropolitan, wilderness, and at-sea that met the working group's requirements. Using prototypical technologies from Boeing, On Ramp, and Fortress, SRNL was able to demonstrate the ability to track personnel and material in all scenarios including indoors, in heavily wooden areas, canyons, and in parking garages. In all cases GPS signals were too weak to measure. Bi-directional communication was achieved in areas that Wi-Fi, cell towers, or traditional radios would not perform. The results of the exercise will be presented. These technologies are considered ideal for tracking high value material such has nuclear material with a platform that allows seamless tracking anywhere in the world, indoors or outdoors.

Global Failure Criteria for Positive/Electrolyte/Negative Structure of Planar Solid Oxide Fuel Cell  

Science Conference Proceedings (OSTI)

Due to mismatch of the coefficients of thermal expansion of various layers in the positive/electrolyte/negative (PEN) structures of solid oxide fuel cells (SOFC), thermal stresses and warpage on the PEN are unavoidable due to the temperature changes from the stress-free sintering temperature to room temperature during the PEN manufacturing process. In the meantime, additional mechanical stresses will also be created by mechanical flattening during the stack assembly process. In order to ensure the structural integrity of the cell and stack of SOFC, it is necessary to develop failure criteria for SOFC PEN structures based on the initial flaws occurred during cell sintering and stack assembly. In this paper, the global relationship between the critical energy release rate and critical curvature and maximum displacement of the warped cells caused by the temperature changes as well as mechanical flattening process is established so that possible failure of SOFC PEN structures may be predicted deterministically by the measurement of the curvature and displacement of the warped cells.

Characteristics of Deep GPS Signal Fading Due to Ionospheric Scintillation for Aviation Receiver Design  

E-Print Network (OSTI)

Aircraft navigation based on GPS (Global Positioning System) and WAAS (Wide Area Augmentation System) requires both code and carrier measurements to calculate the position estimate [1]. A GPS receiver’s carrier tracking loop is weaker than code tracking loop. Thus, carrier lock can more easily be broken under deep signal fading caused by ionospheric scintillation. If a receiver cannot track code and carrier of at least four satellite channels, the aircraft cannot navigate using GPS or WAAS. The solar maximum data set analyzed in this research demonstrates frequent deep fades and almost all satellites in view suffered from scintillation, which could significantly reduce number of simultaneous tracked satellites. Statistics of number of tracked satellites under 45 minutes of strong scintillation are given in this paper and importance of shorter reacquisition time of a receiver is also emphasized. In order to design an aviation receiver with shorter reacquisition time under frequent deep signal fadings, characteristics of signal fading have to be well understood. Two important characteristics of deep fading are analyzed, which are fading duration and time between deep fades. The fading duration model in this paper can provide a guideline for more robust aviation receiver design. Even if the receiver could reacquire phase lock quickly, frequent deep fades significantly increase noise level in smoothed pseudoranges, which results in lower navigation availability. Statistics of time between deep fades given in this paper shows very frequent deep fades that could be a major concern of GPS navigation under strong scintillation during solar maximum period.

Why there is no noon-midnight red shift in the GPS  

E-Print Network (OSTI)

Although the effects of solar (and lunar) gravitational potentials on the frequencies of orbiting Global Positioning System (GPS) clocks are actually no more than a few parts in 10^(15), a na\\"ive calculation appears to show that such effects are much larger, and depend on whether the orbiting clock is between the earth and the sun, or on the side of the earth opposite to the sun. Consequently questions about whether such effects have been properly accounted for in the GPS continue to arise. This issue has been discussed in a misleading way in terms of cancellations arising from a second-order Doppler shift in the literature for almost 50 years. The purpose of this article is to provide a correct argument, based on fundamental relativity principles, so that one may understand in a simple way why the effects of external solar system bodies on orbiting or earth-bound clocks in the GPS are so small. The relativity of simultaneity plays a crucial role in these arguments.

Shoreline monitoring program on the Upper Texas Coast utilizing a Real-Time Kinematic Differential Global Positioning System  

E-Print Network (OSTI)

Due to shoreline erosion, approximately seventeen miles of Texas State Highway 87, located in Jefferson County Texas, have been repeatedly destroyed by storms and rebuilt. This thesis describes a shoreline monitoring program developed to obtain a comprehensive data set that will be used to define the coastal erosion problem and assist in the reconstruction of the roadway. An improved survey system similar to a concept developed by Beach et al. (1996) was designed and constructed for this project. This thesis discusses the improved survey system design and testing. The nearshore system utilizes a Real-Time Kinematic Differential Global Positioning System (RTK-DGPS) mounted on a personal watercraft and integrated with a survey quality echo sounder. The nearshore system was tested by repeating transects in the nearshore. The repeatability of the profiles demonstrated a standard deviation of 6.2 cm from the mean absolute difference of 8.0 cm. The beach survey utilizes RTK-DGPS equipment carried by the surveyor in a backpack. The maximum expected error for the beach survey is approximately []4 cm. The system is an accurate, mobile and efficient method to obtain beach profiles. Additional accuracy may be obtained by integrating a motion sensor and CTD profiler. The survey data are processed using commercially available software packages and programs developed for this project. The processed data is integrated and stored in a geographic information system (GIS). The data collected exemplify morphological features indicative of erosion due to overwash. This is consistent with visual observations and numerical model results provided by Howard (1999). The shoreline movement since 1996 is consistent with historical data and is related to storm events. The current research has provided a survey system capable of performing fast, accurate surveys in the nearshore and a baseline data set. The survey system is fully operational and will be instrumental in the ongoing research related to the Highway 87 reconstruction project. The baseline data set, together with sediment analyses data and water level predictions, provides the foundation from which further investigations will be conducted and will provide information that can be used for the design of the new highway.

Ekofisk automatic GPS subsidence measurements  

Science Conference Proceedings (OSTI)

A fully automatic GPS satellite-based procedure for the reliable measurement of subsidence of several platforms in almost real time is described. Measurements are made continuously on platforms in the North Sea Ekofisk Field area. The procedure also yields rate measurements, which are also essential for confirming platform safety, planning of remedial work, and verification of subsidence models. GPS measurements are more attractive than seabed pressure-gauge-based platform subsidence measurements-they are much cheaper to install and maintain and not subject to gauge drift. GPS measurements were coupled to oceanographic quantities such as the platform deck clearance, which leads to less complex offshore survey procedures. Ekofisk is an oil and gas field in the southern portion of the Norwegian North Sea. Late in 1984, it was noticed that the Ekofisk platform decks were closer to the sea surface than when the platforms were installed-subsidence was the only logical explanation. After the subsidence phenomenon was recognized, an accurate measurement method was needed to measure progression of subsidence and the associated subsidence rate. One available system for which no further development was needed, was the NAVSTAR GPS-measurements started in March 1985.

POSITIONING DEVICE  

DOE Patents (OSTI)

A positioner is described for a vertical reactor-control rod. The positioner comprises four grooved friction rotatable members that engage the control rod on all sides and shift it longitudinally. The four friction members are drivingly interconnected for conjoint rotation and comprise two pairs of coaxial members. The members of each pair are urged toward one another by hydraulic or pneumatic pressure and thus grip the control rod so as to hold it in any position or adjust it. Release of the by-draulic or pneumatic pressure permits springs between the friction members of each pair to force them apart, whereby the control rod moves quickly by gravity into the reactor.

GPS Data Filtration Method for Drive Cycle Analysis Applications  

SciTech Connect

When employing GPS data acquisition systems to capture vehicle drive-cycle information, a number of errors often appear in the raw data samples, such as sudden signal loss, extraneous or outlying data points, speed drifting, and signal white noise, all of which limit the quality of field data for use in downstream applications. Unaddressed, these errors significantly impact the reliability of source data and limit the effectiveness of traditional drive-cycle analysis approaches and vehicle simulation software. Without reliable speed and time information, the validity of derived metrics for drive cycles, such as acceleration, power, and distance, become questionable. This study explores some of the common sources of error present in raw onboard GPS data and presents a detailed filtering process designed to correct for these issues. Test data from both light and medium/heavy duty applications are examined to illustrate the effectiveness of the proposed filtration process across the range of vehicle vocations. Graphical comparisons of raw and filtered cycles are presented, and statistical analyses are performed to determine the effects of the proposed filtration process on raw data. Finally, an evaluation of the overall benefits of data filtration on raw GPS data and present potential areas for continued research is presented.

Global warming and global dioxide emission: An empirical study  

Science Conference Proceedings (OSTI)

In this paper, the dynamic relationship between global surface temperature (global warming) and global carbon dioxide emission (CO{sub 2}) is modelled and analyzed by causality and spectral analysis in the time domain and frequency domain, respectively. Historical data of global CO{sub 2} emission and global surface temperature anomalies over 129 years from 1860-1988 are used in this study. The causal relationship between the two phenomena is first examined using the Sim and Granger causality test in the time domain after the data series are filtered by ARIMA models. The Granger causal relationship is further scrutinized and confirmed by cross-spectral and multichannel spectral analysis in the frequency domain. The evidence found from both analyses proves that there is a positive causal relationship between the two variables. The time domain analysis suggests that Granger causality exists between global surface temperature and global CO{sub 2} emission. Further, CO{sub 2} emission causes the change in temperature. The conclusions are further confirmed by the frequency domain analysis, which indicates that the increase in CO{sub 2} emission causes climate warming because a high coherence exists between the two variables. Furthermore, it is proved that climate changes happen after an increase in CO{sub 2} emission, which confirms that the increase in CO{sub 2} emission does cause global warming. 27 refs., 10 figs., 5 tabs.

Arterial Performance and Evaluation using Bluetooth and GPS Data  

E-Print Network (OSTI)

Accurate travel time data are necessary to monitor and evaluate traffic conditions effectively. In the past 20 years, the hours per year lost by the average driver have increased by 300% in the 85 largest U.S. cities, which translates into lost productivity and increased costs. State department of transportation (DOT) agencies and other government organizations need accurate travel time and speed information to better combat this congestion faced by motorists. In the past, ground truth travel time information was typically collected with probe vehicles using the “floating car” method. However, new methods using data collected from global positioning systems by private companies such as INRIX®, Navteq®, and TomTom® have emerged that allow travel time data to be obtained more cheaply and quickly. The Urban Mobility Report (UMR) has turned to these companies, specifically INRIX®, for calculating congestion indices across the United States. This is done by analyzing average speeds and reference speeds supplied by INRIX. The UMR analysis relies on INRIX-supplied reference speeds to calculate delay, which produces artificially high delay on many suburban arterials. Currently, these reference speeds are determined by taking the 85th percentile of weekly speeds (typically overnight hours [10PM to 6AM]). There is a need to refine the reference speeds on arterials in order to account for signal operations, particularly during the daytime hours, so that the UMR more accurately reflects arterial congestion across the nation. Using Bluetooth and INRIX speed data, this thesis develops a new reference speed methodology that accurately reflects arterial delay during daytime hours. This study found that a 60% daytime free-flow reference speed best represents arterial congestion. Using Highway Capacity Manual (HCM) guidelines, this thesis also explores the use of Bluetooth data for arterial and intersection level of service (LOS) analysis under both HCM 2000 and HCM 2010 methodologies. Through analysis, it was found that Bluetooth data capture more of the high and low LOS values compared to the HCM methodology based on segment speed calculations. These high and low LOS values, as well as the rapidly changing LOS between 15-minute intervals, could be attributed to an insufficient sample size.

Integration of GPS, accelerometer and optical fiber sensors for structural deformation monitoring  

E-Print Network (OSTI)

and Telecommunications. Her current research interests are the integration of RTK-GPS, accelerometer, and optical fiber sensors, and digital signal processing. Monitoring the response of structures, especially tall buildings, under severe loading conditions is an important requirement for the validation of their design and construction, as well as being a maintenance concern. Traditionally such response has been measured using accelerometers. However it is impossible to measure the static or quasi-static components of movement with such sensors. An integrated system comprising RTK-GPS, accelerometer, and optical fiber sensors has been proposed for monitoring structural deformation, with the objective being to assess the integrity of structures. The GPS and accelerometer sensors have been installed on a 108m tall steel tower in Tokyo, together with other sensors such as anemometer and strain gauge. In this paper the seismic and wind-induced responses of the tower are analysed using Fast Fourier Transformation (FFT) of the GPS and accelerometer measurements. Then the correlated signals are extracted by a digital filtering technique. The filtered data sets are also converted to displacement (in the case of accelerometer) and acceleration (in the case of GPS) through double integration and double differentiation respectively, for the purpose of direct comparison. The results agree with each other very well, except that the static component is missing from the accelerometer derived results. Meanwhile, extensive indoor experiments have been conducted to test optical fiber Bragg grating (FBG) sensors for the measurement of distributed strain.

The article proposes a vehicle lane positioning technique based on joint frequency difference of arrival (FDOA) and time difference of arrival (TDOA) principle by measuring Doppler frequency, and derives possible solutions. The vehicle sensor measures the incoming RF signals from a reference emitter at time delayed locations and utilizes the characteristics of this downlink communications to accurately determine the frequency offset as well as time stamp of the packet. The article also addresses the limitations of the technique such as velocity vector estimations at measurement locations and offers possible solutions including Bayesian and triangulation estimation.

Nuclear Fuel Recycling Position Statement  

E-Print Network (OSTI)

The American Nuclear Society believes that if the world is to provide sufficient energy to meet the demands of a growing population and improved standards of living in the 21 st century, nuclear energy will play a substantial role. Nuclear energy is a proven technology that will be part of the mix of technologies used by future generations due to its enormous energy potential with near-zero emissions of greenhouse gases (see related Position Statement 44). Alternative energy sources by themselves will be insufficient to meet these needs during this period of rapidly increasing energy demand. Nuclear fuel recycling, which involves separating the uranium and plutonium from spent nuclear fuel for reuse in the fabrication of new fuel (see Position Statement 47), has the potential to reclaim most of the unused energy in spent fuel. It is a proven alternative to current U.S. policy of direct disposal of spent fuel in a geological repository, which throws away the fuel’s remaining energy content. Recycling of nuclear fuel in other countries with proper safeguards and material controls (see related Position Statement 55) under the auspices of the International Atomic Energy Agency (IAEA) has demonstrated the viability of high level waste volume reduction and energy resource conservation. Transitioning to a recycle policy in an era of expanded nuclear deployment will enhance resource utilization, radioactive waste management, and safeguards. Additional research and development 1 are needed to address the issue of cost and to further enhance the safeguards and safety of the various processes that are required. Such research is also needed to secure the U.S. position as a leader in nuclear technology and global nuclear materials stewardship. Therefore, the American Nuclear Society endorses the following: U.S. policy that allows an orderly transition to nuclear fuel recycling in parallel with the development of the high level waste repository, Yucca Mountain, in a manner that would enhance the repository’s efficiency; further research and development of recycle options to ensure a secure and sustainable energy future with reduced proliferation risks.

Photon position measure  

E-Print Network (OSTI)

The positive operator valued measure (POVM) for a photon counting array detector is derived and found to equal photon flux density integrated over pixel area and measurement time. Since photon flux density equals number density multiplied by the speed of light, this justifies theoretically the observation that a photon counting array provides a coarse grained measurement of photon position. The POVM obtained here can be written as a set of projectors onto a basis of localized states, consistent with the description of photon position in a recent quantum imaging proposal [M. Tsang, Phys. Rev. Lett. \\textbf{102}, 253601 (2009)]. The wave function that describes a photon counting experiment is the projection of the photon state vector onto this localized basis. Collapse is to the electromagnetic vacuum and not to a localized state, thus violating the text book rules of quantum mechanics but compatible with the theory of generalized observables and the nonlocalizability of an incoming photon.

Seismic response of a tower as measured by an integrated RTK-GPS system  

E-Print Network (OSTI)

Monitoring structural response induced by seismic waves is an efficient way to mitigate the damage of earthquakes. For example, the measured signal can be used to activate an alarm system in order to evacuate people from an endangered building, or to drive a control system to suppress earthquake-excited vibrations so as to protect the integrity of the structure, or to assess post-seismic damage to a structure. Traditionally such vibrations have been measured solely by accelerometers. However, it is impossible to measure the static and semi-static components of the movement with accelerometers. An integrated system combining RTK-GPS and accelerometers has been deployed atop a 108m tall tower in Tokyo in order to monitor its structural integrity on a continuous basis. Data acquired during earthquakes are automatically archived. In this paper, the seismic responses of the tower were analysed using Fast Fourier Transformation (FFT) of the GPS and accelerometer measurements. The data were also converted to displacement (in the case of accelerometer) and acceleration (in the case of GPS) through double-integration and double-differentiation respectively, for the purpose of direct comparison. The results agreed with each other well, except that the static component was

FUSION ENERGY Position Statement  

E-Print Network (OSTI)

The American Nuclear Society (ANS) supports a vigorous research and development program for fusion energy. Fusion represents a potential energy source that is sustainable and has favorable safety and environmental features. Like fission, fusion offers the opportunity to generate substantial quantities of energy while producing no CO2 or other “greenhouse gases” that may contribute to global warming. Even with substantial conservation efforts and improvements in end-use efficiency, the future world demand for energy is expected to increase as a result of population growth and economic development. The timely advent of fusion as a practical energy source may be crucial. In particular, the ANS believes the following: 1. The long-term benefits of fusion energy warrant a sustained effort aimed at advancing fusion science and technology. International cooperation is a cost-effective complement to strong national programs. 2. Recent scientific progress in fusion research has been encouraging and warrants an enhanced and expanded fusion engineering and technology development program. 3. Based on the continuing success of physics and technology development programs, it appears

The Global Grid  

E-Print Network (OSTI)

This paper puts forward the vision that a natural future stage of the electricity network could be a grid spanning the whole planet and connecting most of the large power plants in the world: this is the "Global Grid". The main driving force behind the Global Grid will be the harvesting of remote renewable sources, and its key infrastructure element will be the high capacity long transmission lines. Wind farms and solar power plants will supply load centers with green power over long distances. This paper focusses on the introduction of the concept, showing that a globally interconnected network can be technologically feasible and economically competitive. We further highlight the multiple opportunities emerging from a global electricity network such as smoothing the renewable energy supply and electricity demand, reducing the need for bulk storage, and reducing the volatility of the energy prices.

Global irrigation demand - A holistic approach  

Science Conference Proceedings (OSTI)

To develop a research track on global irrigation demand and the use of future water resources to help feed the world, we need to adopt a holistic approach to understand inter-dependencies and the main drivers of the global water system and unravel positive (reinforcing) and negative (balancing) feedback loops that can lead to cascading consequences. Thus, there needs to be more research dedicated to 1) the modeling of the agricultural and water systems as components within an integrated assessment human-Earth modeling framework, 2) the understanding of the linkages between the physical processes and the human system, and to integrate them in an economic framework to capture the dynamics of market price, and institutional regulations. This editorial discusses the importance of tackling the global irrigation problem in an integrated assessment modeling framework.

Positioning system of the ANTARES Neutrino Telescope  

E-Print Network (OSTI)

Completed in May 2008, the ANTARES neutrino telescope is located 40 km off the coast of Toulon, at a depth of about 2500 m. The telescope consists of 12 detect or lines housing a total of 884 optical modules. Each line is anchored to the seabed and pulled taught by the buoyancy of the individual optical modules and a top buoy. Due to the fluid nature of the sea-water detecting medium and the flexible nature of the detector lines, the optical modules of the ANTARES telescope can suffer from deviations of up to several meters from the vertical and as such, real time positioning is needed. Real time positioning of the ANTARES telescope is achieved by a combination of an acoustic positioning system and a lattice of tiltmeters and compasses. These independent and complementary systems are used to compute a global fit to each individual detector line, allowing us to construct a 3 dimensional picture of the ANTARES neutrino telescope with an accuracy of less than 10 cm. In this paper we describe the positioning syst...

Nonproliferation Position Statement  

E-Print Network (OSTI)

For its many benefits to be realized, nuclear technology should continue to be applied in such a way that it does not contribute to the spread of nuclear weapons. In addition, the public must have confidence that the diversion of civil nuclear materials into weapons programs will not happen. An effective nonproliferation policy should prevent diversion by States of fissile material from the nuclear fuel cycle; theft of fissile material by subnational or terrorist groups; clandestine operation of a fissile material production facility. It is the position of the American Nuclear Society (ANS) that the following actions are required to deal with these threats effectively: 1. Nuclear science and technology can be applied for peaceful purposes in a manner that fully supports and is compatible with achieving nonproliferation goals, as embodied in the Treaty on the Nonproliferation of Nuclear Weapons (NPT). To prevent proliferation, sovereign states should adhere to the NPT and its safeguards system including the Additional Protocol and adopt effective export controls. Incentives to acquire nuclear weapons must also be addressed through foreign policies that discourage clandestine

NETL: Global Environmental Benefits  

NLE Websites -- All DOE Office Websites (Extended Search)

Global Environmental Benefits Global Environmental Benefits Gasification Systems Global Environmental Benefits Environmental performance for future energy production systems is a much greater factor as emission standards tighten in the United States and worldwide. The outstanding environmental performance of gasification systems makes it an excellent technology for the clean production of electricity and other products. In addition, the reduction of CO2 emissions is one of the major challenges facing industry in response to global climate change. Other countries with coal reserves might potentially import technologies developed in the United States to enable low-cost gasification with carbon capture and EOR or sequestration. Not only will this benefit the U.S. gasification technology industry, but it will also result in a global environmental benefit through more affordable control of greenhouse gases (GHGs). See the U.S. Environmental Protection Agency (EPA) link below for a summary of the impact of fossil fuels without carbon capture on CO2 emissions, on the GHG contributions of different countries, and of the projected impact of developing countries to 2030:

Global ice sheet modeling  

Science Conference Proceedings (OSTI)

The University of Maine conducted this study for Pacific Northwest Laboratory (PNL) as part of a global climate modeling task for site characterization of the potential nuclear waste respository site at Yucca Mountain, NV. The purpose of the study was to develop a global ice sheet dynamics model that will forecast the three-dimensional configuration of global ice sheets for specific climate change scenarios. The objective of the third (final) year of the work was to produce ice sheet data for glaciation scenarios covering the next 100,000 years. This was accomplished using both the map-plane and flowband solutions of our time-dependent, finite-element gridpoint model. The theory and equations used to develop the ice sheet models are presented. Three future scenarios were simulated by the model and results are discussed.

A-GPS Assisted Wi-Fi Access Point Discovery on Mobile Devices for Energy Saving  

E-Print Network (OSTI)

Mobile devices have been shipped with multiple wireless network interfaces in order to meet their diverse communication and networking demands. In this paper, we propose an A-GPS assisted scheme that discovers the nearest Wi-Fi network access points (APs) by using user's location information. This allows the user to switch to the Wi-Fi interface in an intelligent manner when she/he arrives at the nearest Wi-Fi network AP. Therefore, it avoids the long periods in idle state and greatly reduces the number of unnecessary Wi-Fi scans on the mobile device. The experimental results demonstrate that our scheme effectively saves energy for mobile devices integrated with Wi-Fi and cellular interfaces.

The continuity of the output entropy of positive maps  

SciTech Connect

Global and local continuity conditions for the output von Neumann entropy for positive maps between Banach spaces of trace-class operators in separable Hilbert spaces are obtained. Special attention is paid to completely positive maps: infinite dimensional quantum channels and operations. It is shown that as a result of some specific properties of the von Neumann entropy (as a function on the set of density operators) several results on the output entropy of positive maps can be obtained, which cannot be derived from the general properties of entropy type functions. In particular, it is proved that global continuity of the output entropy of a positive map follows from its finiteness. A characterization of positive linear maps preserving continuity of the entropy (in the following sense: continuity of the entropy on an arbitrary subset of input operators implies continuity of the output entropy on this subset) is obtained. A connection between the local continuity properties of two completely positive complementary maps is considered. Bibliography: 21 titles.

Global Climate Data  

NLE Websites -- All DOE Office Websites (Extended Search)

Data Data The climate data at the ORNL DAAC are used primarily as driving variables in terrestrial biogeochemistry models. These models typically use data on temperature (min,max), precipitation, humidity (relative humidity, vapor pressure deficit, dew point), radiation (PFD in PAR, shortwave, direct/diffuse, and UV radiation, daylength), and wind velocity. Climate / meteorology data are required at hourly to monthly time scales, either point or gridded, at spatial scales ranging from regional to continental to global. The ORNL DAAC currently distributes climate data from several related projects: VEMAP-1 Hydroclimatology, and Global Historical Climatology Network. We are also now distributing climate data developed at the East Anglia Climate Research Unit and the Potsdam Institute for Climate Research.

Global climate feedbacks  

SciTech Connect

The important physical, chemical, and biological events that affect global climate change occur on a mesoscale -- requiring high spatial resolution for their analysis. The Department of Energy has formulated two major initiatives under the US Global Change Program: ARM (Atmospheric Radiation Measurements), and CHAMMP (Computer Hardware Advanced Mathematics and Model Physics). ARM is designed to use ground and air-craft based observations to document profiles of atmospheric composition, clouds, and radiative fluxes. With research and models of important physical processes, ARM will delineate the relationships between trace gases, aerosol and cloud structure, and radiative transfer in the atmosphere, and will improve the parameterization of global circulation models. The present GCMs do not model important feedbacks, including those from clouds, oceans, and land processes. The purpose of this workshop is to identify such potential feedbacks, to evaluate the uncertainties in the feedback processes (and, if possible, to parameterize the feedback processes so that they can be treated in a GCM), and to recommend research programs that will reduce the uncertainties in important feedback processes. Individual reports are processed separately for the data bases.

Global residential appliance standards  

SciTech Connect

In most countries, residential electricity consumption typically ranges from 20% to 40% of total electricity consumption. This energy is used for heating, cooling, refrigeration and other end-uses. Significant energy savings are possible if new appliance purchases are for models with higher efficiency than that of existing models. There are several ways to ensure or encourage such an outcome, for example, appliance rebates, innovative procurement, and minimum efficiency standards. This paper focuses on the latter approach. At the present time, the US is the only country with comprehensive appliance energy efficiency standards. However, many other countries, such as Australia, Canada, the European Community (EC), Japan and Korea, are considering enacting standards. The greatest potential impact of minimum efficiency standards for appliances is in the developing countries (e.g., China and India), where saturations of household appliances are relatively low but growing rapidly. This paper discusses the potential savings that could be achieved from global appliance efficiency standards for refrigerators and freezers. It also could be achieved from global appliance efficiency standards for refrigerators and freezers. It also discusses the impediments to establishing common standards for certain appliance types, such as differing test procedures, characteristics, and fuel prices. A methodology for establishing global efficiency standards for refrigerators and freezers is described.

Although concern about global atmospheric warming has intensified in recent decades, research into the greenhouse effect actually began in the 19th century. Fourier and other scientists appreciated that without heat-absorbing gases in the atmosphere, the temperature on the ground would be considerably lower, making life as we know it impossible. In 1896, the Swedish scientist Svante Arrhenius was the first to make a quantitative link between changes in carbon dioxide concentration and climate. Publication of his paper was celebrated at a recent Swedish workshop. 13 refs., 1 fig.

The Global Energy Challenge  

DOE Green Energy (OSTI)

The expected doubling of global energy demand by 2050 challenges our traditional patterns of energy production, distribution and use. The continued use of fossil fuels raises concerns about supply, security, environment and climate. New routes are needed for the efficient conversion of energy from chemical fuel, sunlight, and heat to electricity or hydrogen as an energy carrier and finally to end uses like transportation, lighting, and heating. Opportunities for efficient new energy conversion routes based on nanoscale materials will be presented, with emphasis on the sustainable energy technologies they enable.

HIERARCHICAL STRUCTURE OF MAGNETOHYDRODYNAMIC TURBULENCE IN POSITION-POSITION-VELOCITY SPACE  

SciTech Connect

Magnetohydrodynamic turbulence is able to create hierarchical structures in the interstellar medium (ISM) that are correlated on a wide range of scales via the energy cascade. We use hierarchical tree diagrams known as dendrograms to characterize structures in synthetic position-position-velocity (PPV) emission cubes of isothermal magnetohydrodynamic turbulence. We show that the structures and degree of hierarchy observed in PPV space are related to the presence of self-gravity and the global sonic and Alfvenic Mach numbers. Simulations with higher Alfvenic Mach number, self-gravity and supersonic flows display enhanced hierarchical structure. We observe a strong dependency on the sonic and Alfvenic Mach numbers and self-gravity when we apply the statistical moments (i.e., mean, variance, skewness, kurtosis) to the leaf and node distribution of the dendrogram. Simulations with self-gravity, larger magnetic field and higher sonic Mach number have dendrogram distributions with higher statistical moments. Application of the dendrogram to three-dimensional density cubes, also known as position-position-position (PPP) cubes, reveals that the dominant emission contours in PPP and PPV are related for supersonic gas but not for subsonic. We also explore the effects of smoothing, thermal broadening, and velocity resolution on the dendrograms in order to make our study more applicable to observational data. These results all point to hierarchical tree diagrams as being a promising additional tool for studying ISM turbulence and star forming regions for obtaining information on the degree of self-gravity, the Mach numbers and the complicated relationship between PPV and PPP data.

Global emissions inventories  

SciTech Connect

Atmospheric chemistry determines the concentrations of most of the important greenhouse gases except for carbon dioxide. The rate of removal of the greenhouse gases from the atmosphere is also controlled by atmospheric chemistry. The indirect effects of chemical forcing resulting from the chemical interactions of other species can also affect the concentrations of radiatively important gases such as ozone. In order to establish the contribution of any possible climatic change attributable to individual greenhouse gases, spatially and temporally resolved estimates of their emissions need to be established. Unfortunately, for most of the radiatively important species the global magnitudes of their individual fluxes are not known to better than a factor of two and their spatial distributions are even more poorly characterized. Efforts to estimate future projections of potential impacts and to monitor international agreements will require continued research to narrow the uncertainties of magnitude and geographical distribution of emissions.

Global Energy Management System  

E-Print Network (OSTI)

Exxon Mobil Corporation has undertaken voluntary actions to continuously improve energy efficiency in our operations for many years. From 1973 to 1999, we improved the energy efficiency of our refineries and chemical plants by over 35 percent - saving the cumulative equivalent of 1.8 billion barrels of oil and reducing carbon dioxide emissions by over 200 million tonnes. In 2000, we redoubled our efforts with deployment of our Global Energy Management System (GEMS), which utilizes international best practices and benchmarking to identify energy efficiencies at each of our refineries and chemical plants. Thus far, we have identified opportunities to improve the energy efficiency of these facilities by an additional 15 to 20 percent. At full implementation, savings are expected to total $500 million to $1 billion per year, with an associated reduction in carbon dioxide emissions of about 10 million tonnes per year - roughly equivalent to removing 1.5 million cars from the world's roads.

Predicting the Market Potential of Plug-In Electric Vehicles Using Multiday GPS Data  

E-Print Network (OSTI)

GPS data for a year’s worth of travel by 255 Seattle households illuminate how plug-in electric vehicles can match household needs. The results suggest that a battery-electric vehicle (BEV) with 100 miles of range should meet the needs of 50 % of one-vehicle households and 80 % of multiple-vehicle households, when charging once a day and relying on another vehicle or mode just 4 days a year. Moreover, the average one-vehicle Seattle household uses each vehicle 23 miles per day and should be able to electrify close to 80 % of its miles using a plug-in hybrid electric vehicle (PHEV) with 40-mile all-electric-range. Households owning two or more vehicles can electrify 50 to 70 % of their miles using a PHEV40, depending on how they assign the vehicle across drivers each day. Cost comparisons between the average single-vehicle household owning a Chevrolet Cruze versus a Volt PHEV suggest that when gas prices are $3.50 per gallon and electricity rates at 11.2 ct per kWh, the Volt will save the household $535 per year in operating costs. Similarly, the Toyota Prius PHEV will provide an annual savings of $538 per year over the Corolla.

Renewable Energy Positioning System: Energy Positioning: Control and Economics  

Science Conference Proceedings (OSTI)

GENI Project: The University of Washington and the University of Michigan are developing an integrated system to match well-positioned energy storage facilities with precise control technologies so the electric grid can more easily include energy from renewable power sources like wind and solar. Because renewable energy sources provide intermittent power, it is difficult for the grid to efficiently allocate those resources without developing solutions to store their energy for later use. The two universities are working with utilities, regulators, and the private sector to position renewable energy storage facilities in locations that optimize their ability to provide and transmit electricity where and when it is needed most. Expanding the network of transmission lines is prohibitively expensive, so combining well-placed storage facilities with robust control systems to efficiently route their power will save consumers money and enable the widespread use of safe, renewable sources of power.

Towards an Infrastructure for Authorization - Position Paper  

E-Print Network (OSTI)

In recent years, there has been a great deal of debate about whether a large-scale "publickey infrastructure" is needed for electronic commerce and, if so, whether the technical difficulty of building and deploying such an infrastructure will impede the growth of electronic commerce. We argue here that much of the controversy is attributable to the fact that the term "public-key infrastructure" has not been clearly and correctly defined. We explain why the informal definition most often associated with the term, i.e., that of a global mapping between users' identities and public keys, is not the right definition for electronic commerce and hence that whether such a mapping can and will be built and deployed with available resources is not an especially pressing question. Finally, we describe an alternative type of infrastructural development that we believe really would enable electronic commerce. 1 Introduction It is our position that the debate over whether a large-scale public-k...

Global production through 2005  

SciTech Connect

Two companion studies released recently should provide great food for thought among geo-political strategists and various national governments. If predictions contained in these Petroconsultants studies of oil and gas production trends for the next 10 years are realized, there will be great repercussions for net exporters and importers, alike. After analyzing and predicting trends within each of the world`s significant producing nations for the 1996--2005 period, the crude oil and condensate report concludes tat global production will jump nearly 24%. By contrast, worldwide gas output will leap 40%. The cast of characters among producers and exporters that will benefit from these increases varies considerably for each fuel. On the oil side, Russia and the OPEC members, particularly the Persian Gulf nations, will be back in the driver`s seat in terms of affecting export and pricing patterns. On the gas side, the leading producers will be an interesting mix of mostly non-OPEC countries. The reemergence of Persian Gulf oil producers, coupled with an anticipated long-term decline among top non-OPEC producing nations should present a sobering picture to government planners within large net importers, such as the US. They are likely to find themselves in much the same supply trap as was experienced in the 1970s, only this time the dependence on foreign oil supplies will be much worse. Gas supplies will not be similarly constrained, and some substitution for oil is probable. Here, two articles, ``World oil industry is set for transition`` and ``Worldwide gas surges forward in next decade,`` present a summary of the findings detailed in Petroconsultants` recent studies.

Diffraction encoded position measuring apparatus  

DOE Patents (OSTI)

When a lightwave passes through a transmission grating, diffracted beams appear at the output or opposite side of the grating that are effectively Doppler shifted in frequency (phase) whereby a detector system can compare the phase of the zero order and higher order beams to obtain an indication of position. Multiple passes through the grating increase resolution for a given wavelength of a laser signal. The resolution can be improved further by using a smaller wavelength laser to generate the grating itself. Since the grating must only have a pitch sufficient to produce diffracted orders, inexpensive, ultraviolet wavelength lasers can be utilized and still obtain high resolution detection. 3 figures.

Clean coal: Global opportunities for small businesses  

Science Conference Proceedings (OSTI)

The parallel growth in coal demand and environmental concern has spurred interest in technologies that burn coal with greater efficiency and with lower emissions. Clean Coal Technologies (CCTs) will ensure that continued use of the world`s most abundant energy resource is compatible with a cleaner, healthier environment. Increasing interest in CCTs opens the door for American small businesses to provide services and equipment for the clean and efficient use of coal. Key players in most coal-related projects are typically large equipment manufacturers, power project developers, utilities, governments, and multinational corporations. At the same time, the complexity and scale of many of these projects creates niche markets for small American businesses with high-value products and services. From information technology, control systems, and specialized components to management practices, financial services, and personnel training methods, small US companies boast some of the highest value products and services in the world. As a result, American companies are in a prime position to take advantage of global niche markets for CCTs. This guide is designed to provide US small businesses with an overview of potential international market opportunities related to CCTs and to provide initial guidance on how to cost-effectively enter that growing global market.

Global Security, Medical Isotopes, and Nuclear Science  

Science Conference Proceedings (OSTI)

Over the past century basic nuclear science research has led to the use of radioactive isotopes into a wide variety of applications that touch our lives everyday. Some are obvious, such as isotopes for medical diagnostics and treatment. Others are less so, such as National/Global security issues. And some we take for granted, like the small amount of 241Am that is in every smoke detector. At the beginning of this century, we are in a position where the prevalence and importance of some applications of nuclear science are pushing the basic nuclear science community for improved models and nuclear data. Yet, at the same time, the push by the basic nuclear science community to study nuclei that are farther and farther away from stability also offer new opportunities for many applications. This talk will look at several global security applications of nuclear science, summarizing current R&D and need for improved nuclear data It will also look at how applications of nuclear science, such as to medicine, will benefit from the push for more and more powerful radioactive ion beam facilities.

Global Cooling: Effect of Urban Albedo on Global Temperature  

SciTech Connect

In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). The roof and the pavement albedo can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60%. We estimate U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills. Increasing albedo of urban surfaces can reduce the summertime urban temperature and improve the urban air quality. Increasing the urban albedo has the added benefit of reflecting more of the incoming global solar radiation and countering the effect of global warming. We estimate that increasing albedo of urban areas by 0.1 results in an increase of 3 x 10{sup -4} in Earth albedo. Using a simple global model, the change in air temperature in lowest 1.8 km of the atmosphere is estimated at 0.01K. Modelers predict a warming of about 3K in the next 60 years (0.05K/year). Change of 0.1 in urban albedo will result in 0.01K global cooling, a delay of {approx}0.2 years in global warming. This 0.2 years delay in global warming is equivalent to 10 Gt reduction in CO2 emissions.

Making Global Illumination User Friendly Making Global Illumination User Friendly Title Making Global Illumination User Friendly Publication Type Conference Paper LBNL Report Number LBL-37860 Year of Publication 1995 Authors Ward, Gregory J. Conference Name 6th Eurographics Workshop on Rendering Date Published 06/1995 Conference Location Dublin, Ireland Call Number LBL-37860 Abstract Global illumination researchers tend to think in terms of mesh density and sampling frequency, and their software reflects this in its user interface. Advanced rendering systems are rife with long command lines and parameters for tuning the sample densities, thresholds and other algorithm-specific variables, and the novice user is quickly lost in a sea of possibilities. This paper details a successful effort of making one such global illumination system usable by people who understand their problems, even if they do not understand the methods needed to solve them, through an assisted oracle approach. A single program is introduced to map a small set of intuitive control variables to the rendering commands and parameter settings needed to produce the desired output in a reasonable time. This new executive program then serves as the basis for a graphical user interface that is both friendly in its appearance and reliable in its performance. Finally, we conclude with some future directions for improving this interface.

Outlook positive over long term  

Science Conference Proceedings (OSTI)

The trends established in 1987 will be very important in reestablishing some level of confidence in future price expectations. The authors expect prices to fluctuate widely in the coming year as OPEC makes and breaks various production quota agreements. Continued price instability will certainly all but negate short term marginally economic exploration and development prospects. Utilization rates will suffer accordingly. But on the positive side, the long term outlook is considerably more stable. Rock-bottom prices will increase the demand for cheap oil substantially. We're already seeing world demand figures rise. Increased demand will cause the world's (mainly OPEC's) excess production to be depleted over the next three to five years. Prices will rise slowly in parallel with the decline in excess production capacity over several years. Banking on upward price pressure, financially sound operators with solid cash flow will want to take advantage of low exploration and development costs. Utilization, then, can be expected to follow oil prices in a slow upward spiral over the next three to five years. Next year, the industry should begin to feel the effect of the beginning of that upward trend.

Motor vehicles and global warming  

SciTech Connect

Energy use in transportation is one of the contributors to the concern over global warming. The primary greenhouse gases released by the transportation sector are carbon dioxide and chlorofluorocarbons. When all greenhouse gases are considered, CO{sub 2} emissions from the operation of highway vehicles worldwide represent about 4.7% of global warming enhancement. CO{sub 2} emissions from U.S. highway vehicles along represent about 2 to 2.5% of worldwide greenhouse gases. The use of CFCs in automotive air conditioning, in blowing foams for seats and padding and in the manufacture of electronic circuit boards accounted for 15% of the global usage of CFC-12 in 1985 according to the U.S. EPA. The Motor Vehicle Manufacturers Association supports the phase-out of CFC use provided that safe substitutes are available and that adequate lead time is allowed for.They suggest that reduction of greenhouse gases would require planning on a global scope to be effective. One alternative they suggest for further study is a carbon fee for reducing emissions of carbon dioxide. This fee would be levied on each type of fossil fuel, proportional to its carbon content per unit of energy.

A Sensor-based Long Baseline Position and Velocity Navigation Filter for Underwater Vehicles  

E-Print Network (OSTI)

This paper presents a novel Long Baseline (LBL) position and velocity navigation filter for underwater vehicles based directly on the sensor measurements. The solution departs from previous approaches as the range measurements are explicitly embedded in the filter design, therefore avoiding inversion algorithms. Moreover, the nonlinear system dynamics are considered to their full extent and no linearizations are carried out whatsoever. The filter error dynamics are globally asymptotically stable (GAS) and it is shown, under simulation environment, that the filter achieves similar performance to the Extended Kalman Filter (EKF) and outperforms linear position and velocity filters based on algebraic estimates of the position obtained from the range measurements.

Local beam position feedback experiments on the ESRF storage ring  

SciTech Connect

This paper describes the results of local beam position feedback experiments conducted on the ESRF storage ring using digital signal processing (DSP) under the trilateral agreement of collaboration among ESRF, APS, and SPring-8. Two rf beam position monitors (BPMS) in the, upstream and downstream of the insertion device (ID) and two x-ray BPMs in the sixth cell were used to monitor the electron beam and the x-ray beam emitted from the ID, respectively. The local bump coefficients were obtained using the technique of singular value decomposition (SVD) on the global response matrix for the bump magnets and all the available BPMs outside the local bump. The local response matrix was then obtained between the two three-magnet bumps and the position monitors. The data sampling frequency was 4 kHz and a proportional, integral, and derivative (PID) controller was used. The result indicates the closed-loop feedback bandwidth close to 100 Hz and clear attenuation ({approx} {minus}40 dB) of the 7-Hz beam motion due to girder vibration resonance. Comparison of the results using the rf BPMs and x-ray BPMs will be also discussed.

Global warming continues in 1989  

SciTech Connect

Nineteen eight-nine ranks as one of the warmest years on record despite the chill of unusually cool water in the tropical Pacific. The continued robustness of the warming trend that began in the mid-1970s lends support to claims that an intensifying greenhouse effect is behind it all, although that case has not yet been made definitively. Even at the current rate of global warming it will take another 10 years or so to be confident that the greenhouse effect is with us. Although the global warming trend is consistent with an increasing contribution by the greenhouse effect, direct signs that the greenhouse effect is intensifying are still hard to come by in the temperature record. Greenhouse models agree that if that is happening, the temperature increase should be most pronounced around the Arctic. Alaska, northwestern Canada, and northern Siberia warmed sharply in the 1980s, but the region from eastern Canada through Greenland and into Scandinavia cooled markedly.

Global Technology Regulation and Potentially  

E-Print Network (OSTI)

In 2000 Bill Joy proposed that the best way to prevent technological apocalypse was to "relinquish " emerging bio-, info- and nanotechnologies. His essay introduced many watchdog groups to the dangers that futurists had been warning of for decades. One such group, ETC, has called for a moratorium on all nanotechnological research until all safety issues can be investigated and social impacts ameliorated. In this essay I discuss the differences and similarities of regulating bio- and nanotechnological innovation to the efforts to regulate nuclear and biological weapons of mass destruction. I then suggest the creation of a global technology regulatory regime to ensure the safe and equitable diffusion of genetic, molecular and information technologies, and point out the principal political obstacles to implementing such a regime.

Implementation of global energy sustainability  

SciTech Connect

The term energy sustainability emerged from the UN Conference on Environment and Development in Rio 1992, when Agenda 21 was formulated and the Global Energy Charter proclaimed. Emission reductions, total energy costing, improved energy efficiency, and sustainable energy systems are the four fundamental principles of the charter. These principles can be implemented in the proposed financial, legal, technical, and education framework. Much has been done in many countries toward the implementation of the Global Energy Charter, but progress has not been fast enough to ease the disastrous effects of the too many ill-conceived energy systems on the environment, climate, and health. Global warming is accelerating, and pollution is worsening, especially in developing countries with their hunger for energy to meet the needs of economic development. Asian cities are now beating all pollution records, and greenhouse gases are visibly changing the climate with rising sea levels, retracting glaciers, and record weather disasters. This article presents why and how energy investments and research money have to be rechanneled into sustainable energy, rather than into the business-as-usual of depleting, unsustainable energy concepts exceeding one trillion dollars per year. This largest of all investment sectors needs much more attention.

E-Print Network (OSTI)

For many years, ExxonMobil has undertaken voluntary actions to improve efficiency in our operations and in customer use of our products. Our Global Energy Management System (GEMS) is an important initiative that is having a positive impact at each of our refineries and chemical plants. The system builds on international best practices and benchmarking to identify energy efficiencies. Launched in 2000, it utilizes a common methodology to identify performance gaps, implement closure plans, sustain progress, and drive energy efficiency toward leading-edge performance. The GEMS business model is based on a three-step approach to performance improvement. First, it addresses base case performance issues by operating existing facilities optimally and efficiently through application of best practices. Second, it identifies economic investment opportunities above an optimized base for step-change improvement to address structural differences. Third, the system implements strong management systems to provide the rigor and discipline necessary to sustain progress and drive continuous improvement. Ultimately, management leadership, organizational commitment, and personal accountability all work together to drive continuous improvement.

ERROR COMPENSATOR FOR A POSITION TRANSDUCER  

DOE Patents (OSTI)

A device is designed for eliminating the effect of leadscrew errors in positioning machines in which linear motion of a slide is effected from rotary motion of a leadscrew. This is accomplished by providing a corrector cam mounted on the slide, a cam follower, and a transducer housing rotatable by the follower to compensate for all the reproducible errors in the transducer signal which can be related to the slide position. The transducer has an inner part which is movable with respect to the transducer housing. The transducer inner part is coupled to the means for rotating the leadscrew such that relative movement between this part and its housing will provide an output signal proportional to the position of the slide. The corrector cam and its follower perform the compensation by changing the angular position of the transducer housing by an amount that is a function of the slide position and the error at that position.

Economic Globalization and a Nuclear Renaissance  

Science Conference Proceedings (OSTI)

The phenomenon of globalization has become increasingly well recognized, documented, and analyzed in the last several years. Globalization, the integration of markets and intra-firm competition on a worldwide basis, involves complex behavioral and mindset changes within a firm that facilitate global competition. The changes revolve around efficient information flow and rapid deployment of technology. The objective of this report is to examine the probable characteristics of a global nuclear renaissance and its broad implications for industry structure and export control relative to nuclear technology. The question of how a modern renaissance would affect the trend toward globalization of the nuclear industry is addressed.

Plasma position dynamics of ISX tokamak  

SciTech Connect

Perturbation equations of a tokamak plasma equilibrium position have been developed. Neglecting second and higher order effects, oscillatory high frequency solution is obtained, and an approximated low frequency plasma motion dynamics transfer function is derived. This function allows a manageable study of a tokamak plasma equilibrium position stability and practical syntheses of the associated plasma position feedback control systems. One of the major parameters governing plasma equilibrium position stability of a tokamak is shown to be the vacuum vessel eddy current delay time constant.

Positional reference system for ultraprecision machining  

DOE Patents (OSTI)

A stable positional reference system for use in improving the cutting tool-to-part contour position in numerical controlled-multiaxis metal turning machines is provided. The reference system employs a plurality of interferometers referenced to orthogonally disposed metering bars which are substantially isolated from machine strain induced position errors for monitoring the part and tool positions relative to the metering bars. A microprocessor-based control system is employed in conjunction with the plurality of position interferometers and part contour description data inputs to calculate error components for each axis of movement and output them to corresponding axis drives with appropriate scaling and error compensation. Real-time position control, operating in combination with the reference system, makes possible the positioning of the cutting points of a tool along a part locus with a substantially greater degree of accuracy than has been attained previously in the art by referencing and then monitoring only the tool motion relative to a reference position located on the machine base.

Electronic Position Sensor for Power Operated Accessory  

DOE Patents (OSTI)

An electronic position sensor for use with a power operated vehicle accessory, such as a power liftgate. The position sensor includes an elongated resistive circuit that is mounted such that it is stationary and extends along the path of a track portion of the power operated accessory. The position sensor further includes a contact nub mounted to a link member that moves within the track portion such that the contact nub is slidingly biased against the elongated circuit. As the link member moves under the force of a motor-driven output gear, the contact nub slides along the surface of the resistive circuit, thereby affecting the overall resistance of the circuit. The position sensor uses the overall resistance to provide an electronic position signal to an ECU, wherein the signal is indicative of the absolute position of the power operated accessory. Accordingly, the electronic position sensor is capable of providing an electronic signal that enables the ECU to track the absolute position of the power operated accessory.

International conference on the role of the polar regions in global change: Proceedings. Volume 1  

Science Conference Proceedings (OSTI)

The International Conference on the Role of the Polar Regions in Global Change took place on the campus of the University of Alaska Fairbanks on June 11--15, 1990. The goal of the conference was to define and summarize the state of knowledge on the role of the polar regions in global change, and to identify gaps in knowledge. To this purpose experts in a wide variety of relevant disciplines were invited to present papers and hold panel discussions. While there are numerous conferences on global change, this conference dealt specifically with polar regions which occupy key positions in the global system. These two volumes of conference proceedings include papers on (1) detection and monitoring of change; (2) climate variability and climate forcing; (3) ocean, sea ice, and atmosphere interactions and processes; (4) effects on biota and biological feedbacks; (5) ice sheet, glacier and permafrost responses and feedbacks; (6) paleoenvironmental studies; and, (7) aerosols and trace gases.

Heard Island global warming test  

SciTech Connect

In late January and early February 1991, an international team will conduct an experiment to test the possibility of measuring global warming in the world's oceans. The goal is to provide early indications of warming caused by the so-called greenhouse effect, the atmospheric buildup of CO{sub 2} and other gases. The method is based on the principle that acoustic energy travels through water between a source and receiver at a speed determined primarily by the water temperature. Thus acoustic travel time can be used as a temperature gauge. The idea is an outgrowth of suggestions made by Professor Walter Munk of the Scripps Institution of Oceanography and Professor Carl Wunsch of MIT in the early 1980s to use long-range underwater acoustic transmissions to measure changes in the heat content of the oceans.

Interim report on the Global Design Effort Global International Linear Collider (ILC) R&D  

Science Conference Proceedings (OSTI)

The International Linear Collider: A Technical Progress Report marks the halfway point towards the Global Design Effort fulfilling its mandate to follow up the ILC Reference Design Report with a more optimised Technical Design Report (TDR) by the end of 2012. The TDR will be based on much of the work reported here and will contain all the elements needed to propose the ILC to collaborating governments, including a technical design and implementation plan that are realistic and have been better optimised for performance, cost and risk. We are on track to develop detailed plans for the ILC, such that once results from the Large Hadron Collider (LHC) at CERN establish the main science goals and parameters of the next machine, we will be in good position to make a strong proposal for this new major global project in particle physics. The two overriding issues for the ILC R&D programme are to demonstrate that the technical requirements for the accelerator are achievable with practical technologies, and that the ambitious physics goals can be addressed by realistic ILC detectors. This GDE interim report documents the impressive progress on the accelerator technologies that can make the ILC a reality. It highlights results of the technological demonstrations that are giving the community increased confidence that we will be ready to proceed with an ILC project following the TDR. The companion detector and physics report document likewise demonstrates how detector designs can meet the ambitious and detailed physics goals set out by the ILC Steering Committee. LHC results will likely affect the requirements for the machine design and the detectors, and we are monitoring that very closely, intending to adapt our design as those results become available.

We constructively prove the existence of time-discrete consumption processes for stochastic money accounts that fulfill a pre-specified positively homogeneous projection property (PHPP) and let the account always be positive and exactly zero at the end. One possible example is consumption rates forming a martingale under the above restrictions. For finite spaces, it is shown that any strictly positive consumption strategy with restrictions as above possesses at least one corresponding PHPP and could be constructed from it. We also consider numeric examples under time-discrete and -continuous account processes, cases with infinite time horizons and applications to income drawdown and bonus theory.

Position Sensitive Detection System for Charged Particles  

Science Conference Proceedings (OSTI)

The position sensitive detection system presented in this work employs the Anger logic algorithm to determine the position of the light spark produced by the passage of charged particles on a 170 x 170 x 10 mm3 scintillator material (PILOT-U). The detection system consists of a matrix of nine photomultipliers, covering a fraction of the back area of the scintillators. Tests made with a non-collimated alpha particle source together with a Monte Carlo simulation that reproduces the data, suggest an intrinsic position resolution of up to 6 mm is achieved.

More data needed to support or disprove global warming theory  

SciTech Connect

Reports of global warming are prevalent in the popular press. With the exception of Scandinavia, no major energy tax laws have been passed to date. But environmental pressures may change this, and the change could have a profound effect on refiners. These are the views of Gerald T. Westbrook, of TSBV Consultants, Houston. Westbrook summarized recent global-warming research, and his position on the subject, at the National Petroleum Refiners Association annual meeting, held March 16--18, in San Antonio. The greenhouse effect is real, says Westbrook. It is important, however, to distinguish between the two major mechanisms of the greenhouse effect: natural warming and anthropogenic warming (changes in the concentration of greenhouse gases caused by man). Without greenhouse gases the earth`s equilibrium temperature would be {minus}18 C. The effect of the gases is to raise the equilibrium temperature to 15 C. In the early 1980s, computer models estimated global warming over the past 100 years to be as much as 2.3 C. By 1986, those estimates had been reduced to 1.0 C, and in 1988, a range of 0.63 {+-} 0.2 C was reported. In 1995, a report by the Intergovernmental Panel on Climate change (IPCC) cited a range of 0.3--0.6 C. Westbrook asserts that the earth`s motion anomalies--orbit eccentricity, axial tilt, and wobbles--lead to dramatic changes in insolation, and are the dominant force over the last 160,000 years.

Refugees And A Global Cosmopolitan Democracy – Empowerment or Political Aspiration?  

E-Print Network (OSTI)

This paper engages with the application of David Held’s proposed democratic reform of international regulatory and legal institutions as they pertain to refugee protection and administration. The implications of Held’s short-term proposals for the refugee protection community will be discussed on the basis of making international governing institutions more accountable, investing compulsory jurisdiction in an International Court and creating a democratic global law. In light of the emancipative potential of cosmopolitan democratic theory, this paper assesses whether the above reforms could provide a tangible solution to the refugee ‘problem’. The main contention of this paper is that there is a dilemma in using democracy as a vehicle for creating a cosmopolitan democratic law. On the one hand, instantiation of a global cosmopolitan law is needed to regulate the active participation of those affected by trans-border movements so that the refugee community can be liberated from the constraints of the law of nations and positive international law. On the other hand, there is currently no democratic consensus amongst states to create global legal institutions to enhance, let alone enforce refugee

GMG: A Guaranteed, Efficient Global Optimization Algorithm for Remote Sensing.  

SciTech Connect

The monocular passive ranging (MPR) problem in remote sensing consists of identifying the precise range of an airborne target (missile, plane, etc.) from its observed radiance. This inverse problem may be set as a global optimization problem (GOP) whereby the difference between the observed and model predicted radiances is minimized over the possible ranges and atmospheric conditions. Using additional information about the error function between the predicted and observed radiances of the target, we developed GMG, a new algorithm to find the Global Minimum with a Guarantee. The new algorithm transforms the original continuous GOP into a discrete search problem, thereby guaranteeing to find the position of the global minimum in a reasonably short time. The algorithm is first applied to the golf course problem, which serves as a litmus test for its performance in the presence of both complete and degraded additional information. GMG is further assessed on a set of standard benchmark functions and then applied to various realizations of the MPR problem.

Side-emitting fiber optic position sensor  

SciTech Connect

A side-emitting fiber optic position sensor and method of determining an unknown position of an object by using the sensor. In one embodiment, a concentrated beam of light source illuminates the side of a side-emitting fiber optic at an unknown axial position along the fiber's length. Some of this side-illuminated light is in-scattered into the fiber and captured. As the captured light is guided down the fiber, its intensity decreases due to loss from side-emission away from the fiber and from bulk absorption within the fiber. By measuring the intensity of light emitted from one (or both) ends of the fiber with a photodetector(s), the axial position of the light source is determined by comparing the photodetector's signal to a calibrated response curve, look-up table, or by using a mathematical model. Alternatively, the side-emitting fiber is illuminated at one end, while a photodetector measures the intensity of light emitted from the side of the fiber, at an unknown position. As the photodetector moves further away from the illuminated end, the detector's signal strength decreases due to loss from side-emission and/or bulk absorption. As before, the detector's signal is correlated to a unique position along the fiber.

The positive ion temperature effect in magnetized electronegative plasma sheath with two species of positive ions  

Science Conference Proceedings (OSTI)

The properties of a magnetized multi-component (two species of positive ions, negative ions and electrons) plasma sheath with finite positive ion temperature are studied. By using three fluid hydrodynamic model and some dimensionless variables, the ion (both lighter and heavier positive ions, and negative ions) densities, the ion (only for positive ions) velocities, and electric potential inside the sheath are investigated. In addition, the absence and presence of magnetic field and the orientation of magnetic field are considered. It is noticed that, with increase of positive ion temperature, the lighter positive ion density peaks increase only at the sheath edge and shift towards the sheath edge for both absence and presence of magnetic field. For heavier positive ions, in the absence of magnetic field, the density peaks increase at the sheath edge. But in the presence of magnetic field, the density fluctuations increase at the sheath edge. For both the cases, the density peaks shift towards the sheath edge.

Global warming risk in Russia: National actions and some options for international cooperation  

SciTech Connect

In the management of global environmental risks the Russia case is a special one regarding certain specific features which determine the position of the country, particularly in a new international community emerged on the territory of the former Soviet Union, large scientific interest to the global physical processes and low interest and capabilities to deal with such risks on the part of social institutions inherited from the USSR. The largest country in the world with visible geopolitical role and probably biggest regional differences could not be ignored as a one of major players in the management of global environmental risks. The understanding of all deficiencies and positive sides of global risks management process in this country are absolutely important for extrapolating the appropriate trends in some other parts of the world. At the same time the ex-Soviet Union case shows clearly how the social learning process can radically ``change the course``, diverting to the opposite direction the social goals and preferences. Starting the studies on possibilities to change the climate for improving the human being, the former soviet society perceived the risks of human impact on climate and started to regulate it and to participate in the process of international management of global warming. The level of activity in this process on the part of Russia will however depend heavily on how much national interests will be reflected in the specific prevention measures realized by the international community.

Micro-position sensor using faraday effect  

DOE Patents (OSTI)

A micro-position sensor and sensing system using the Faraday Effect. The sensor uses a permanent magnet to provide a magnetic field, and a magneto-optic material positioned in the magnetic field for rotating the plane of polarization of polarized light transmitted through the magneto-optic material. The magnet is independently movable relative to the magneto-optic material so as to rotate the plane of polarization of the polarized light as a function of the relative position of the magnet. In this manner, the position of the magnet relative to the magneto-optic material may be determined from the rotated polarized light. The sensing system also includes a light source, such as a laser or LED, for producing polarized light, and an optical fiber which is connected to the light source and to the magneto-optic material at a sensing end of the optical fiber. Processing electronics, such as a polarimeter, are also provided for determining the Faraday rotation of the plane of polarization of the back-reflected polarized light to determine the position of the magnet relative to the sensing end of the optical fiber.

RFID tags: Positioning principles and localization techniques  

E-Print Network (OSTI)

Abstract—RFID is an automatic identification technology that enables tracking of people and objects. Both identity and location are generally key information for indoor services. An obvious and interesting method to obtain these two types of data is to localize RFID tags attached to devices or objects or carried by people. However, signals in indoor environments are generally harshly impaired and tags have very limited capabilities which pose many challenges for positioning them. In this work, we propose a classification and survey the current state-of-art of RFID localization by first presenting this technology and positioning principles. Then, we explain and classify RFID localization techniques. Finally, we discuss future trends in this domain. Index Terms—RFID, localization, positioning algorithm. I.

Method of manufacturing positive nickel hydroxide electrodes  

DOE Patents (OSTI)

A method of manufacturing a positive nickel hydroxide electrode is discussed. A highly porous core structure of organic material having a fibrous or reticular texture is uniformly coated with nickel powder and then subjected to a thermal treatment which provides sintering of the powder coating and removal of the organic core material. A consolidated, porous nickel support structure is thus produced which has substantially the same texture and porosity as the initial core structure. To provide the positive electrode including the active mass, nickel hydroxide is deposited in the pores of the nickel support structure.

Positivity of Some Integral Transforms, and Generalization of Bochner's Theorem on Functions of Positive Type  

E-Print Network (OSTI)

Using the integral representations of the solutions of Schr\\"odinger equation, which are the essential ingredients of the Gel'fand-Levitan and Marchenko integral equations of inverse scattering theory, we obtain a general theorem on the positivity of some integral transforms, and extend the theorem of Bochner on Fourier transforms of functions of positive type to more general transforms. The present study is restricted to the positive half-axis. We then obtain a theorem on the positivity of Fourier cosine transform of the phase-shifts.

Positive and inverse isotope effect on superconductivity  

E-Print Network (OSTI)

This article improves the BCS theory to include the inverse isotope effect on superconductivity. An affective model can be deduced from the model including electron-phonon interactions, and the phonon-induced attraction is simply and clearly explained on the electron Green function. The focus of this work is on how the positive or inverse isotope effect occurs in superconductors.

Global Warming in Geologic Time  

Science Conference Proceedings (OSTI)

The notion is pervasive in the climate science community and in the public at large that the climate impacts of fossil fuel CO2 release will only persist for a few centuries. This conclusion has no basis in theory or models of the atmosphere/ ocean carbon cycle, which we review here. The largest fraction of the CO2 recovery will take place on time scales of centuries, as CO2 invades the ocean, but a significant fraction of the fossil fuel CO2, ranging in published models in the literature from 20-60%, remains airborne for a thousand years or longer. Ultimate recovery takes place on time scales of hundreds of thousands of years, a geologic longevity typically associated in public perceptions with nuclear waste. The glacial/interglacial climate cycles demonstrate that ice sheets and sea level respond dramatically to millennial-timescale changes in climate forcing. There are also potential positive feedbacks in the carbon cycle, including methane hydrates in the ocean, and peat frozen in permafrost, that are most sensitive to the long tail of the fossil fuel CO2 in the atmosphere.

Global climate change and pedogenic carbonates  

SciTech Connect

Global Climate Change summarizes what is known about soil inorganic carbon and develops strategies that could lead to the retention of more carbon in the soil. It covers basic concepts, analytical methods, secondary carbonates, and research and development priorities. With this book one will get a better understanding of the global carbon cycle, organic and inorganic carbon, and their roles, or what is known of them, in the greenhouse effect.

Article mounting and position adjustment stage  

DOE Patents (OSTI)

An improved adjustment and mounting stage of the type used for the detection of laser beams is disclosed. A ring sensor holder has locating pins on a first side thereof which are positioned within a linear keyway in a surrounding housing for permitting reciprocal movement of the ring along the keyway. A rotatable ring gear is positioned within the housing on the other side of the ring from the linear keyway and includes an oval keyway which drives the ring along the linear keyway upon rotation of the gear. Motor-driven single-stage and dual (x, y) stage adjustment systems are disclosed which are of compact construction and include a large laser transmission hole. 6 figs.

Multigigahertz beam-current and position monitor  

SciTech Connect

A self-integrating magnetic-loop device having a risetime of less than 175 ps has been developed to monitor the temporal behavior of the electron beam current and position within each 3.3-ns micropulse generated by the PHERMEX rf linear accelerator. Beam current is measured with a 2-GHz bandwidth by combining these loops in a four-port hybrid summer. Another application of these loops uses two 180/sup 0/ hybrids to give 2-GHz time-resolved beam position to an accuracy of 1 mm. These sensors are nonintrusive to the propagating beam and allow ultrafast beam measurements previously restricted to the technique of recording the Cerenkov-light emission from an intercepting Kapton foil using a streak camera.

Television news coverage of global warming  

Science Conference Proceedings (OSTI)

Citizens are expressing increased concern over the number and variety of environmental problems. Global warming in particular is a focus of concern for scientists and environmental groups. Such concern should naturally motivate individuals to seek information about these topics. Many people turn to the media, most usually television, for information on the nature of these problems. Consequently, this paper studied media coverage of environmental issues, specifically global warming. Television coverage was examined for: (1) the general nature of coverage; (2) biases in coverage; (3) visual images used to cover global warming; and (4) the congruity between visual and verbal messages in newscasts. Nightly newscasts from the three major American television networks were analyzed from 1993--1995 to determine the overall nature of global warming coverage since the Earth Summit in 1992. Results indicated that television news suffers from some serious inadequacies in its portrayal of global warming issues. The paper concludes by first discussing how its results intertwine with other work in the global warming and mass media field. Finally, the implications of inadequacies in media coverage for policy-makers when it comes to sound management of critical resources in this area are also discussed.

Silent Positioning in Underwater Acoustic Sensor Networks  

E-Print Network (OSTI)

In this paper, we present a silent positioning scheme termed as UPS for underwater acoustic sensor networks. UPS relies on the time-difference of arrivals measured locally at a sensor to detect range differences from the sensor to four anchor nodes. These range differences are averaged over multiple beacon intervals before they are combined to estimate the 3D sensor location through trilateration. UPS requires no time-synchronization and provides location privacy at underwater vehicles/sensors whose locations need to be determined. To study the performance of UPS, we model the underwater acoustic channel as a modified Ultra Wide Band (UWB) S-V model: the arrival of each path cluster and paths within each cluster follow double Poisson distributions, and the multipath channel gain follows a Rician distribution. Based on this channel model, we perform both theoretical analysis and simulation study on the position error of UPS under acoustic fading channels. The obtained results indicate that UPS is an effective scheme for underwater vehicle/sensor self-positioning.
