Understanding BL Lac objects Structural & kinematic mode changes in the BL Lac object PKS 0735+178  

E-Print Network (OSTI)

Context. We present evidence that parsec-scale jets in BL Lac objects may be significantly distinct in kinematics from their counterparts in quasars. We argued this previously for the BL lac sources 1803+784 and 0716+714, report here a similar pattern for another well-known BL Lac object, PKS 0735+178, whose nuclear jet is found to exhibit kinematics atypical of quasars. Aims. A detailed study of the jet components' motion reveals that the standard AGN paradigm of apparent superluminal motion does not always describe the kinematics in BL Lac objects. We study 0735+178 here to augment and improve the understanding of the peculiar motions in the jets of BL Lac objects as a class. Methods. We analyzed 15 GHz VLBA (Very Long Baseline Array) observations (2cm/MOJAVE survey) performed at 23 epochs between 1995.27 and 2008.91. Results. We found a drastic structural mode change in the VLBI jet of 0735+178, between 2000.4 and 2001.8 when its twice sharply bent trajectory turned into a linear shape.We further found tha...

Growing bubbles in a slightly supersaturated liquid solution  

E-Print Network (OSTI)

We have designed and constructed an experimental system to study gas bubble growth in slightly supersatu- rated liquids. This is achieved by working with carbon dioxide dissolved in water, pressurized at a maximum of 1 MPa and applying a small pressure drop from saturation conditions. Bubbles grow from hydrophobic cavities etched on silicon wafers, which allows us to control their number and position. Hence, the experiment can be used to investigate the interaction among bubbles growing in close proximity when the main mass transfer mechanism is diffusion and there is a limited availability of the dissolved species.

The slightly-enriched spectral shift control reactor  

SciTech Connect

An advanced converter reactor design utilizing mechanical spectral shift control rods in a conventional pressurized water reactor configuration is under investigation. The design is based on the principle that a harder spectrum during the early part of the fuel cycle will result in large neutron captures in fertile {sup 238}U, which can then be burned in situ in a softer spectrum later in the cycle. Preliminary design calculations performed during FY 89 showed that the slightly-enriched spectral shift reactor design offers the benefit of substantially increased fuel resource utilization with the proven safety characteristics of the pressurized water reactor technology retained. Optimization of the fuel design and development of fuel management strategies were carried out in FY 90, along with effort to develop and validate neutronic methodology for tight-lattice configurations with hard spectra. During FY 91, the final year of the grant, the final Slightly-Enriched Spectral Shift Reactor (SESSR) design was determined, and reference design analyses were performed for the assemblies as well as the global core configuration, both at the beginning of cycle (BOC) and with depletion. The final SESSR design results in approximately a 20% increase in the utilization of uranium resources, based on equilibrium fuel cycle analyses. Acceptable pin power peaking is obtained with the final core design, with assembly peaking factors equal to less than 1.04 for spectral shift control rods both inserted and withdrawn, and global peaking factors at BOC predicted to be 1.4. In addition, a negative Moderation Temperature Coefficient (MTC) is maintained for BOC, which is difficult to achieve with conventional advanced converter designs based on a closed fuel cycle. The SESSR design avoids the need for burnable poison absorber, although they could be added if desired to increase the cycle length while maintaining a negative MTC.

FUEL CYCLE COSTS IN A GRAPHITE MODERATED SLIGHTLY ENRICHED FUSED SALT REACTOR  

SciTech Connect

A fuel cycle economic study has been made for a 315Mwe graphite- moderated slightly enriched fused-salt reactor. Fuel cycle costs of less than 1.5 mills may be possible for such reactors operating on a ten-year cycle even when the fuel is discarded at the end of the cycle. Recovery of the uranium and plutonium at the end of the cycle reduces the fuel cycle costs to approximates 1 mill/kwh. Changes in the waste storage cost, reprocessing cost or salt inventory have a relatively minor effect on fuel cycle costs. (auth)

Neutronic Study of Slightly Modified Water Reactors and Application to Transition Scenarios  

SciTech Connect

In this paper we have studied slightly modified water reactors and their applications to transition scenarios. The PWR and CANDU reactors have been considered. New fuels based on Thorium have been tested: Thorium/Plutonium and Thorium/Uranium- 233, with different fissile isotope contents. Changes in the geometry of the assemblies were also explored to modify the moderation ratio, and consequently the neutron flux spectrum. A core equivalent assembly methodology was introduced as an exploratory approach and to reduce the computation time. Several basic safety analyses were also performed. We have finally developed a new scenario code, named OSCAR (Optimized Scenario Code for Advanced Reactors), to study the efficiency of these modified reactors in transition to Gen IV reactors or in symbiotic fleet.

A Numerical Investigation into the Anomalous Slight NOx Increase when Burning Biodiesel: A New (Old) Theory  

DOE Green Energy (OSTI)

Biodiesel is a notable alternative to petroleum derived diesel fuel because it comes from natural domestic sources and thus reduces dependence on diminishing petroleum fuel from foreign sources, it likely lowers lifecycle greenhouse gas emissions, and it lowers an engine's emission of most pollutants as compared to petroleum derived diesel. However, the use of biodiesel often slightly increases a diesel engine's emission of smog forming nitrogen oxides (NO{sub x}) relative to petroleum diesel. In this paper, previously proposed theories for this slight NOx increase are reviewed, including theories based on biodiesel's cetane number, which leads to differing amounts of charge preheating, and theories based on the fuel's bulk modulus, which affects injection timing. This paper proposes an additional theory for the slight NO{sub x} increase of biodiesel. Biodiesel typically contains more double bonded molecules than petroleum derived diesel. These double bonded molecules have a slightly higher adiabatic flame temperature, which leads to the increase in NOx production for biodiesel. Our theory was verified using numerical simulations to show a NOx increase, due to the double bonded molecules, that is consistent with observation. Further, the details of these numerical simulations show that NOx is predominantly due to the Zeldovich mechanism.

Electrostatic Patch Effect in Cylindrical Geometry. I. Potential and Energy between Slightly Non-Coaxial Cylinders  

E-Print Network (OSTI)

We study the effect of any uneven voltage distribution on two close cylindrical conductors with parallel axes that are slightly shifted in the radial and by any length in the axial direction. The investigation is especially motivated by certain precision measurements, such as the Satellite Test of the Equivalence Principle (STEP). By energy conservation, the force can be found as the energy gradient in the vector of the shift, which requires determining potential distribution and energy in the gap. The boundary value problem for the potential is solved, and energy is thus found to the second order in the small transverse shift, and to lowest order in the gap to cylinder radius ratio. The energy consists of three parts: the usual capacitor part due to the uniform potential difference, the one coming from the interaction between the voltage patches and the uniform voltage difference, and the energy of patch interaction, entirely independent of the uniform voltage.

Parallel Objects and Field Equations  

E-Print Network (OSTI)

This paper considers a generalization of the existing concept of parallel (with respect to a given connection) geometric objects and its possible usage as a suggesting rule in searching for adequate field equations in theoretical physics. The generalization tries to represent mathematically the two-sided nature of the physical objects, the {\\it change} and the {\\it conservation}. The physical objects are presented mathematically by sections $\\Psi$ of vector bundles, the admissible changes $D\\Psi$ are described as a rsult of the action of appropriate differential operators $D$ on these sections, and the conservation propertieis are accounted for by the requirement that suitable projections of $D\\Psi$ on $\\Psi$ and on other appropriate sections must be zero. It is shown that the most important equations of theoretical physics obey this rule. Extended forms of Maxwell and Yang-Mills equations are also considered.

average gasoline and diesel fuel prices expected to be average gasoline and diesel fuel prices expected to be slightly lower in 2013 than in 2012 Despite the recent run-up in gasoline prices, the U.S. Energy Information Administration expects falling crude oil prices will lead to a small decline in average motor fuel costs this year compared with last year. The price for regular gasoline is expected to average $3.55 a gallon in 2013 and $3.39 next year, according to EIA's new Short-Term Energy Outlook. That's down from $3.63 a gallon in 2012. For the short-term, however, pump prices are expected to peak at $3.73 per gallon in May because of higher seasonal fuel demand and refiners switching their production to make cleaner burning gasoline for the summer. Diesel fuel will continue to cost more than gasoline because of strong global demand for diesel.

Objective Bayesian nets  

E-Print Network (OSTI)

I present a formalism that combines two methodologies: objective Bayesianism and Bayesian nets. According to objective Bayesianism, an agent’s degrees of belief (i) ought to satisfy the axioms of probability, (ii) ought to satisfy constraints imposed by background knowledge, and (iii) should otherwise be as non-committal as possible (i.e. have maximum entropy). Bayesian nets offer an efficient way of representing and updating probability functions. An objective Bayesian net is a Bayesian net representation of the maximum entropy probability function. I show how objective Bayesian nets can be constructed, updated and combined, and how they can deal with cases in which the agent’s background knowledge includes knowledge of qualitative influence relationships, e.g. causal influences. I then sketch a number of applications of the resulting formalism, showing how it can shed light on probability logic, causal modelling, logical reasoning, semantic reasoning, argumentation

The effect of slightly faster strain rates and internal hydrogen on uranium-0. 8 weight percent titanium alloy mechanical properties  

DOE Green Energy (OSTI)

Mechanical testing of uranium-0.8 wt % titanium (U-0.8 wt % Ti) alloys can affect the outcome of mechanical properties, primarily ductility, by varying the crosshead velocity, which changes the strain rate. However, most specifications that govern mechanical properties of this alloy reference ASTM E-8, which limits the speed to 0.5 in./in. of gage length per minute. Our current procedure for testing U-0.8 Ti is not at the maximum speed permitted in ASTM E-8, so an experiment was designed to evaluate the effect of maximizing the crosshead velocity per ASTM E-8. In order to create a fair assessment, tensile specimens were prepared that were low in internal hydrogen (0.02 ppM) and higher in internal hydrogen (0.36 ppM). External hydrogen effects were minimized by testing in a controlled environment that contained less than 10% relative humidity. Test results showed that for the low hydrogen test group, increasing the crosshead velocity caused a significant increase in reduction in area (RA), but not in elongation. For the higher hydrogen test group, increasing the speed resulted in a significant increase in RA and an increase, though not statistically significant, in elongation. Of equal importance was an observation that strongly suggests a correlation between material defects, like inclusion clusters, and higher hydrogen content, especially at the slower strain rate that would explain the erratic behavior in ductile properties associated with this alloy. As a result of this study, increasing the crosshead velocity to 0.32 in./min is recommended for mechanical testing of U-0.8 Ti alloys. 9 refs., 4 figs., 5 tabs.

Illumination Invariant Object Recognition  

E-Print Network (OSTI)

Varying illumination is a severe problem for existing face recognition algorithms. Altering the light direction from left to right, for example, causes a change of contrast in large face regions and lets most face recognition algorithms fail. Theoretical results, based on the law of incoherent light superposition, provide the solid ground on which a new illumination invariant recognition algorithm is derived. A face recognition experiment demonstrates that this algorithm indeed shows improved recognition performance even if the conditions, for which the theoretical results were derived, do not hold exactly. 1. A STATIC SCENE'S PICTURE SET UNDER VARYING LIGHTING Consider a static scene, lighted with a finite number N s of static light sources that may vary in luminance. These light sources can have arbitrary spatial extent and emit an arbitrary distribution of light. Let i 0 k denote the picture that is produced if only light source k is switched on with a unit luminance and call th...

Laser scanning system for object monitoring  

DOE Patents (OSTI)

A laser scanner is located in a fixed position to have line-of-sight access to key features of monitored objects. The scanner rapidly scans pre-programmed points corresponding to the positions of retroreflecting targets affixed to the key features of the objects. The scanner is capable of making highly detailed scans of any portion of the field of view, permitting the exact location and identity of targets to be confirmed. The security of an object is verified by determining that the cooperative target is still present and that its position has not changed. The retroreflecting targets also modulate the reflected light for purposes of returning additional information back to the location of the scanner.

Acoustic Characterization of Mesoscale Objects  

SciTech Connect

This report describes the science and engineering performed to provide state-of-the-art acoustic capabilities for nondestructively characterizing mesoscale (millimeter-sized) objects--allowing micrometer resolution over the objects entire volume. Materials and structures used in mesoscale objects necessitate the use of (1) GHz acoustic frequencies and (2) non-contacting laser generation and detection of acoustic waves. This effort demonstrated that acoustic methods at gigahertz frequencies have the necessary penetration depth and spatial resolution to effectively detect density discontinuities, gaps, and delaminations. A prototype laser-based ultrasonic system was designed and built. The system uses a micro-chip laser for excitation of broadband ultrasonic waves with frequency components reaching 1.0 GHz, and a path-stabilized Michelson interferometer for detection. The proof-of-concept for mesoscale characterization is demonstrated by imaging a micro-fabricated etched pattern in a 70 {micro}m thick silicon wafer.

Thermodynamics of magnetized binary compact objects  

Science Conference Proceedings (OSTI)

Binary systems of compact objects with electromagnetic field are modeled by helically symmetric Einstein-Maxwell spacetimes with charged and magnetized perfect fluids. Previously derived thermodynamic laws for helically symmetric perfect-fluid spacetimes are extended to include the electromagnetic fields, and electric currents and charges; the first law is written as a relation between the change in the asymptotic Noether charge {delta}Q and the changes in the area and electric charge of black holes, and in the vorticity, baryon rest mass, entropy, charge and magnetic flux of the magnetized fluid. Using the conservation laws of the circulation of magnetized flow found by Bekenstein and Oron for the ideal magnetohydrodynamic fluid, and also for the flow with zero conducting current, we show that, for nearby equilibria that conserve the quantities mentioned above, the relation {delta}Q=0 is satisfied. We also discuss a formulation for computing numerical solutions of magnetized binary compact objects in equilibrium with emphasis on a first integral of the ideal magnetohydrodynamic-Euler equation.

Microbial and objective quality of whole muscle beef cuts packaged in film containing chlorine dioxide  

E-Print Network (OSTI)

The microbial and objective quality of top round steak treated with two deferent prototype chlorine dioxide containing films were evaluated deleing 14 days of refrigerated storage. The films were designed to deliver different dose rates of chlorine dioxide when in contact with tissue. A high dose rate film in combination with dip treatments resulted in a 1.0 log?? reduction of total hemophilic aerobes, total coliforms, and total lactic acid bacteria. However, this same film caused undesirable characteristics including the rapid loss of the red color associated with fresh beef and the development of a green colored pigment. This color change corresponded to a decrease in Hunter a* values. Ascorbic acid treatments slightly inhibited the development of green color after 2 days of storage, but the protective effect was not evident after 6 days of storage and the color remained undesirable. Chlorine dioxide released from the high dose rate film penetrated immediately into the surface of the beef to a depth of 1mm into the surface of the beef after 6 days of storage, and did not penetrate more than 2mm deep after 14 days of storage. The concentration of myoglobin in extracts of the treated samples decreased sharply after 2 days storage, suggesting oxidative degradation and possibly the formation of a compound similar to the green pigment cholemyoglobin. The TBA values of beef treated with the high dose rate film increased during storage but remained blow 1.0. A low chlorine dioxide dose rate film did not produce any microbiological or objective changes in the beef. The dose rate for the high dose rate film was 32ppm/h, as determined by neutron activation analysis. It decreased rapidly to 0ppm/h after 10 days storage and was not constant during the test period. Based on the unacceptable attributes produced by the high dose rate film, it may be better suited for low fat cuts of pork, ash, or chicken that are less susceptible to color changes and quality losses associated with undesirable oxidative changes.

Cost objective PLM and CE  

E-Print Network (OSTI)

Concurrent engineering taking into account product life-cycle factors seems to be one of the industrial challenges of the next years. Cost estimation and management are two main strategic tasks that imply the possibility of managing costs at the earliest stages of product development. This is why it is indispensable to let people from economics and from industrial engineering collaborates in order to find the best solution for enterprise progress for economical factors mastering. The objective of this paper is to present who we try to adapt costing methods in a PLM and CE point of view to the new industrial context and configuration in order to give pertinent decision aid for product and process choices. A very important factor is related to cost management problems when developing new products. A case study is introduced that presents how product development actors have referenced elements to product life-cycle costs and impacts, how they have an idea bout economical indicators when taking decisions during the progression of the project of product development.

Geophysics-based method of locating a stationary earth object  

DOE Patents (OSTI)

A geophysics-based method for determining the position of a stationary earth object uses the periodic changes in the gravity vector of the earth caused by the sun- and moon-orbits. Because the local gravity field is highly irregular over a global scale, a model of local tidal accelerations can be compared to actual accelerometer measurements to determine the latitude and longitude of the stationary object.

Energy Monitoring - Objectives vs Results  

E-Print Network (OSTI)

Universities, hospitals and similar institutions as well as manufacturers and plants have implemented programs of utility submetering. Submetering of utilities is defined as the measurement of energy at or near the point of use as opposed to gross measurement of energy coming into a building or facility. Without exception, the results achieved have met or exceeded expectations. Most of the programs are continuing in an expanding mode. Results of improvements to the utility distribution system can be measured in reduced usage and improved efficiency after submetering is in place. Networking of this monitoring system further enhances information collection and analysis. When other factors such as outside temperature and time of day are included in the data base, an emerging picture of energy usage for an entire facility is developed. A summary of highlights from several of these programs will be discussed in terms of what has been and is being accomplished. The importance of the commitment of both management and technologists/operators becomes evident as the initial objectives are achieved and expanded to match the innovation and skills of these professionals. The programs highlighted represent a group of progressive companies and institutions which have joined a "savings club." We are familiar with the savings clubs based on the investment of capital, depending strictly on interest to generate funds for us. The kind of savings clubs to be discussed in this paper joins capital with the more important human element to generate significant savings in deferred energy expenses. Steps necessary to "join the club" are listed and the ingredients of commitment and planning are discussed.

3D Object Digitization: Majority Interpolation and Marching Cubes  

E-Print Network (OSTI)

In a previous paper we showed that a 3D object can be digitized without changing the topology if the object is r-regular and if the reconstruction method fulfills certain requirements. In this paper we give two important examples for such reconstruction methods. First, we introduce Majority Interpolation, an algorithm to interpolate sampling points at doubled resolution such that topological ambiguities are resolved. Second, we show how the well-known Marching Cubes algorithm has to be modified such that it is topology preserving. This is the first approach of digitizing 3D objects which guarantees topology preservation for voxel-based or polygonal surface-based reconstructions. 1

Computer Aided Design Modeling for Heterogeneous Objects  

E-Print Network (OSTI)

Heterogeneous object design is an active research area in recent years. The conventional CAD modeling approaches only provide geometry and topology of the object, but do not contain any information with regard to the materials of the object and so can not be used for the fabrication of heterogeneous objects (HO) through rapid prototyping. Current research focuses on computer-aided design issues in heterogeneous object design. A new CAD modeling approach is proposed to integrate the material information into geometric regions thus model the material distributions in the heterogeneous object. The gradient references are used to represent the complex geometry heterogeneous objects which have simultaneous geometry intricacies and accurate material distributions. The gradient references helps in flexible manipulability and control to heterogeneous objects, which guarantees the local control over gradient regions of developed heterogeneous objects. A systematic approach on data flow, processing, computer visualizat...

Interpreted C , Object Oriented Tcl, What next?  

E-Print Network (OSTI)

Tcl[1] is an interpreted high level language suitable for scripts, small scale systems, prototypes and embedding in larger applications. C++ is a powerful compiled language that provides support for object oriented programming and is suitable for building large complex systems. But what if you could move from C++ to Tcl and back again with the ease of an object reference and a dynamically bound function? This paper describes an extension to Tcl, or an extension to C++ depending on your perspective, that makes it possible to: O use object oriented programming concepts in Tcl O inherit from C++ classes (with dynamic binding of methods) in Tcl O instantiate C++ classes from Tcl O invoke methods upon C++ objects from Tcl O delete C++ objects from Tcl O pass Tcl objects to C++ for method invocation and deletion. The name of this extension (Tcl++ was rejected) is Object Tcl. 1 Introduction Tcl was originally designed to be embedded in larger applications, implemented ...

Compressive Object Tracking using Entangled Photons  

E-Print Network (OSTI)

We present a compressive sensing protocol that tracks a moving object by removing static components from a scene. The implementation is carried out on a ghost imaging scheme to minimize both the number of photons and the number of measurements required to form a quantum image of the tracked object. This procedure tracks an object at low light levels with fewer than 3% of the measurements required for a raster scan, permitting us to more effectively use the information content in each photon.

Object-Oriented Modeling Of Hybrid Systems  

E-Print Network (OSTI)

A new methodology for the object--oriented description of models consisting of a mixture of continuous and discrete components is presented. The object--oriented paradigm enables the user to describe such models in a modular fashion that permits the reuse of these models independently of the environment in which they are to be embedded. The paper explains the basic mechanisms needed for object--oriented modeling of hybrid systems by means of language constructs available in the object--oriented modeling language Dymola. It then addresses more advanced concepts such as variable structure models containing e.g. ideal electrical switches, ideal diodes and dry friction.

MetaVM: A Transparent Distributed Object System Supported by Runtime Compiler  

E-Print Network (OSTI)

MetaVM is a distributed object system for Java virtual machine. It allows programmers to deal with remote objects in the same way they do local objects. Therefore, it can provide a single machine image to programmers. We implemented a runtime compiler of Java bytecode to provide the facilities. The runtime compiler generates a native code which can handle remote objects beyond the network besides the local objects. The compiler uses semantic expansion, which is a technique that changes the original semantics of a Java bytecode.

Ergoregion instability of ultracompact astrophysical objects  

Science Conference Proceedings (OSTI)

Most of the properties of black holes can be mimicked by horizonless compact objects such as gravastars and boson stars. We show that these ultracompact objects develop a strong ergoregion instability when rapidly spinning. Instability time scales can be of the order of 0.1 seconds to 1 week for objects with mass M=1-10{sup 6}M{sub {center_dot}} and angular momentum J>0.4M{sup 2}. This provides a strong indication that ultracompact objects with large rotation are black holes. Explosive events due to ergoregion instability have a well-defined gravitational-wave signature. These events could be detected by next-generation gravitational-wave detectors such as Advanced LIGO or LISA.

Supermassive Objects as Gamma-Ray Bursters  

E-Print Network (OSTI)

We propose that the gravitational collapse of supermassive objects ($ M\\ga 10^4 M_\\odot$), either as relativistic star clusters or as single supermassive stars (which may result from stellar mergers in dense star clusters), could be a cosmological source of $\\gamma$-ray bursts. These events could provide the seeds of the supermassive black holes observed at the center of many galaxies. Collapsing supermassive objects will release a fraction of their huge gravitational binding energy as thermal neutrino pairs. We show that the accompanying neutrino/antineutrino annihilation-induced heating could drive electron/positron ``fireball'' formation, relativistic expansion, and associated $\\gamma$-ray emission. The major advantage of this model is its energetics: supermassive object collapses are far more energetic than solar mass-scale compact object mergers; therefore, the conversion of gravitational energy to fireball kinetic energy in the supermassive object scenario need not be highly efficient, nor is it necessary to invoke directional beaming. The major weakness of this model is difficulty in avoiding a baryon loading problem for one dimensional collapse scenarios.

Distributed object environment for manufacturing. Final report  

DOE Green Energy (OSTI)

This project was initiated as a joint effort between the Department of Energy (DOE) and Ford to accelerate the development of integrated manufacturing systems through the use of emerging object-oriented software integration architectures and international product data standards. The project adopted the Object Management Group (OMG) Common Object Request Broker Architecture (CORBA) as the formal model for system integration and the ISO Standard for Exchange of Product Model Data (STEP) as the formal model for product data integration. No project at the time had brought the combined strengths of CORBA and STEP together to create an integrated system. Because CORBA technologies were just emerging when this project was started in September 1994, a reasonably high risk was assigned to this project. The first objective of this project was to build confidence in the STEP standard by exchanging a STEP description of a power steering pump with a Ford supplier and validating the exchange. This part was successfully exchanged. The second objective was the integration of the Ford in-house configuration management system with a STEP repository using CORBA-based technology. The repository chosen was the KCP Advanced Manufacturing Development System (AMDS), a development repository. This report will describe the power steering pump exchange and CORBA/STEP integration experiences.

This book outlines the basic physical principles and practical methods of polarimetric remote sensing of Solar System objects and summarizes numerous advanced applications of polarimetry in geophysics and planetary astrophysics. In the first chapter we present a complete and rigorous theory of electromagnetic scattering by disperse media directly based on the Maxwell equations and describe advanced physically based modeling tools. This is followed, in Chapter 2, by a theoretical analysis of polarimetry as a remote-sensing tool and an outline of basic principles of polarimetric measurements and their practical implementations. In Chapters 3 and 4, we describe the results of extensive ground-based, aircraft, and spacecraft observations of numerous Solar System objects (the Earth and other planets, planetary satellites, Saturn's rings, asteroids, trans-Neptunian objects, and comets). Theoretical analyses of these data are used to retrieve optical and physical characteristics of planetary surfaces and atmospheres...

Operating articulated objects based on experience  

E-Print Network (OSTI)

Abstract — Many tasks that would be of benefit to users in domestic environments require that robots manipulate articulated objects such as doors and drawers. In this paper, we present a novel approach that simultaneously estimates the kinematic model of an articulated object based on the trajectory described by the robot’s end effector, and uses this model to predict the future trajectory of the end effector. One advantage of our approach is that the robot can directly use these predictions to generate an equilibrium point control path for operating the mechanism. Additionally, our approach can improve these predictions based on previously learned articulation models. We have implemented and tested our approach on a real mobile manipulator. Through 40 trials, we show that the robot can reliably open various household objects, including cabinet doors, sliding doors, office drawers, and a dishwasher. Furthermore, we demonstrate that using the information from previous interactions as a prior significantly improves the prediction accuracy. I.

Homodyne impulse radar hidden object locator  

DOE Patents (OSTI)

An electromagnetic detector is designed to locate an object hidden behind a separator or a cavity within a solid object. The detector includes a PRF generator for generating 2 MHz pulses, a homodyne oscillator for generating a 2 kHz square wave, and for modulating the pulses from the PRF generator. A transmit antenna transmits the modulated pulses through the separator, and a receive antenna receives the signals reflected off the object. The receiver path of the detector includes a sample and hold circuit, an AC coupled amplifier which filters out DC bias level shifts in the sample and hold circuit, and a rectifier circuit connected to the homodyne oscillator and to the AC coupled amplifier, for synchronously rectifying the modulated pulses transmitted over the transmit antenna. The homodyne oscillator modulates the signal from the PRF generator with a continuous wave (CW) signal, and the AC coupled amplifier operates with a passband centered on that CW signal. The present detector can be used in several applications, including the detection of metallic and non-metallic objects, such as pipes, studs, joists, nails, rebars, conduits and electrical wiring, behind wood wall, ceiling, plywood, particle board, dense hardwood, masonry and cement structure. The detector is portable, light weight, simple to use, inexpensive, and has a low power emission which facilitates the compliance with Part 15 of the FCC rules. 15 figs.

Homodyne impulse radar hidden object locator  

DOE Patents (OSTI)

An electromagnetic detector is designed to locate an object hidden behind a separator or a cavity within a solid object. The detector includes a PRF generator for generating 2 MHz pulses, a homodyne oscillator for generating a 2 kHz square wave, and for modulating the pulses from the PRF generator. A transmit antenna transmits the modulated pulses through the separator, and a receive antenna receives the signals reflected off the object. The receiver path of the detector includes a sample and hold circuit, an AC coupled amplifier which filters out DC bias level shifts in the sample and hold circuit, and a rectifier circuit connected to the homodyne oscillator and to the AC coupled amplifier, for synchronously rectifying the modulated pulses transmitted over the transmit antenna. The homodyne oscillator modulates the signal from the PRF generator with a continuous wave (CW) signal, and the AC coupled amplifier operates with a passband centered on that CW signal. The present detector can be used in several applications, including the detection of metallic and non-metallic objects, such as pipes, studs, joists, nails, rebars, conduits and electrical wiring, behind wood wall, ceiling, plywood, particle board, dense hardwood, masonry and cement structure. The detector is portable, light weight, simple to use, inexpensive, and has a low power emission which facilitates the compliance with Part 15 of the FCC rules.

Help:SubObjects | Open Energy Information  

Open Energy Info (EERE)

SubObjects SubObjects Jump to: navigation, search Subobjects are a nifty way to create any number sets of fields on a page. For example, you might have pages describing movies, the actors in them and reviews. The basic information about the movie just goes in the movie template. The actors can be combined into a single field and their information looked up as needed (you'd have a different type of page for each actor). But for the reviews, you want to have the person making the review, the number of stars, the actual review, and maybe something else. Having a separate page for each review just doesn't make sense - that's where subobjects come in. The subobject would be the combination of required fields (name, stars, review) and people could easily add another review right from the form. And as you'll see, you can do things like

Architectural Implications for Spatial Object Association Algorithms  

Science Conference Proceedings (OSTI)

Spatial object association, also referred to as cross-match of spatial datasets, is the problem of identifying and comparing objects in two or more datasets based on their positions in a common spatial coordinate system. In this work, we evaluate two crossmatch algorithms that are used for astronomical sky surveys, on the following database system architecture configurations: (1) Netezza Performance Server R, a parallel database system with active disk style processing capabilities, (2) MySQL Cluster, a high-throughput network database system, and (3) a hybrid configuration consisting of a collection of independent database system instances with data replication support. Our evaluation provides insights about how architectural characteristics of these systems affect the performance of the spatial crossmatch algorithms. We conducted our study using real use-case scenarios borrowed from a large-scale astronomy application known as the Large Synoptic Survey Telescope (LSST).

Chemistry of Low Mass Substellar Objects  

E-Print Network (OSTI)

"Brown dwarfs" is the collective name for objects more massive than giant planets such as Jupiter but less massive than M dwarf stars. This review gives a brief description of the classification and chemistry of low mass dwarfs. The current spectral classification of stars includes L and T dwarfs that encompass the coolest known stars and substellar objects. The relatively low atmospheric temperatures and high total pressures in substellar dwarfs lead to molecular gas and condensate chemistry. The chemistry of elements such as C, N, O, Ti, V, Fe, Cr, and the alkali elements play a dominant role in shaping the optical and infrared spectra of the "failed" stars. Chemical diagnostics for the subclassifications are described.

An Interactive Simulation Framework for Burning Objects  

E-Print Network (OSTI)

We present a simulation framework to integrate several aspects of the combustion and burning process in a unified and modular manner. A simple three gas flame model is used to simulate a combustion process, while air motion is simulated as a single moving fluid. Solid objects inside the simulation domain can catch fire and start burning. Heat information is transferred from the fluid simulator to a solid simulator, while the solid simulator injects fuel into the fluid simulation. We also present a simple yet effective method for modeling of object decomposition under combustion using level set methods. The interaction between modules is presented as well as a discussion of fluid-solid coupling. All simulation modules run together at interactive rates, enabling the user to tweak the simulation parameters and setup for desired behavior 1. 1

Optical inspection system for cylindrical objects  

SciTech Connect

In the inspection of cylindrical objects, particularly O-rings, the object is translated through a field of view and a linear light trace is projected on its surface. An image of the light trace is projected on a mask, which has a size and shape corresponding to the size and shape which the image would have if the surface of the object were perfect. If there is a defect, light will pass the mask and be sensed by a detector positioned behind the mask. Preferably, two masks and associated detectors are used, one mask being convex to pass light when the light trace falls on a projection from the surface and the other concave, to pass light when the light trace falls on a depression in the surface. The light trace may be either dynamic, formed by a scanned laser beam, or static, formed by such a beam focussed by a cylindrical lens. Means are provided to automatically keep the illuminating receiving systems properly aligned.

Infrared system for monitoring movement of objects  

DOE Patents (OSTI)

A system is described for monitoring moving objects, such as the flight of honeybees and other insects, using a pulsed laser light source. This system has a self-powered micro-miniaturized transmitting unit powered, in the preferred embodiment, with an array of solar cells. This transmitting unit is attached to the object to be monitored. These solar cells provide current to a storage energy capacitor to produce, for example, five volts for the operation of the transmitter. In the simplest embodiment, the voltage on the capacitor operates a pulse generator to provide a pulsed energizing signal to one or more very small laser diodes. The pulsed light is then received at a receiving base station using substantially standard means which converts the light to an electrical signal for processing in a microprocessor to create the information as to the movement of the object. In the case of a unit for monitoring honeybees and other insects, the transmitting unit weighs less than 50 mg, and has a size no larger than 1[times]3[times]5 millimeters. Also, the preferred embodiment provides for the coding of the light to uniquely identify the particular transmitting unit that is being monitored. A wake-up' circuit is provided in the preferred embodiment whereby there is no transmission until the voltage on the capacitor has exceeded a pre-set threshold. Various other uses of the motion-detection system are described. 4 figures.

Objective analysis of toolmarks in forensics  

SciTech Connect

Since the 1993 court case of Daubert v. Merrell Dow Pharmaceuticals, Inc. the subjective nature of toolmark comparison has been questioned by attorneys and law enforcement agencies alike. This has led to an increased drive to establish objective comparison techniques with known error rates, much like those that DNA analysis is able to provide. This push has created research in which the 3-D surface profile of two different marks are characterized and the marks’ cross-sections are run through a comparative statistical algorithm to acquire a value that is intended to indicate the likelihood of a match between the marks. The aforementioned algorithm has been developed and extensively tested through comparison of evenly striated marks made by screwdrivers. However, this algorithm has yet to be applied to quasi-striated marks such as those made by the shear edge of slip-joint pliers. The results of this algorithm’s application to the surface of copper wire will be presented. Objective mark comparison also extends to comparison of toolmarks made by firearms. In an effort to create objective comparisons, microstamping of firing pins and breech faces has been introduced. This process involves placing unique alphanumeric identifiers surrounded by a radial code on the surface of firing pins, which transfer to the cartridge’s primer upon firing. Three different guns equipped with microstamped firing pins were used to fire 3000 cartridges. These cartridges are evaluated based on the clarity of their alphanumeric transfers and the clarity of the radial code surrounding the alphanumerics.

Difficulties for Compact Composite Object Dark Matter  

E-Print Network (OSTI)

It has been suggested ``that DM particles are strongly interacting composite macroscopically large objects ... made of well known light quarks (or ... antiquarks)." In doing so it is argued that these compact composite objects (CCOs) are ``natural explanations of many observed data, such as [the] 511 keV line from the bulge of our galaxy" observed by INTEGRAL and the excess of diffuse gamma-rays in the 1-20 MeV band observed by COMPTEL. Here we argue that the atmospheres of positrons that surround CCOs composed of di-antiquark pairs in the favoured Colour-Flavour-Locked superconducting state are sufficiently dense as to stringently limit the penetration of interstellar electrons incident upon them, resulting in an extreme suppression of previously estimated rates of positronium, and hence the flux of 511 keV photons resulting from their decays, and also in the rate of direct electron-positron annihilations, which yield the MeV photons proposed to explain the 1-20 MeV excess. We also demonstrate that even if a fraction of positrons somehow penetrated to the surface of the CCOs, the extremely strong electric fields generated from the bulk antiquark matter would result in the destruction of positronium atoms long before they decay.

Enforcing Secure Object Initialization in Java  

E-Print Network (OSTI)

Sun and the CERT recommend for secure Java development to not allow partially initialized objects to be accessed. The CERT considers the severity of the risks taken by not following this recommendation as high. The solution currently used to enforce object initialization is to implement a coding pattern proposed by Sun, which is not formally checked. We propose a modular type system to formally specify the initialization policy of libraries or programs and a type checker to statically check at load time that all loaded classes respect the policy. This allows to prove the absence of bugs which have allowed some famous privilege escalations in Java. Our experimental results show that our safe default policy allows to prove 91% of classes of java.lang, java.security and javax.security safe without any annotation and by adding 57 simple annotations we proved all classes but four safe. The type system and its soundness theorem have been formalized and machine checked using Coq.

Tank safety screening data quality objective. Revision 1  

DOE Green Energy (OSTI)

The Tank Safety Screening Data Quality Objective (DQO) will be used to classify 149 single shell tanks and 28 double shell tanks containing high-level radioactive waste into safety categories for safety issues dealing with the presence of ferrocyanide, organics, flammable gases, and criticality. Decision rules used to classify a tank as ``safe`` or ``not safe`` are presented. Primary and secondary decision variables used for safety status classification are discussed. The number and type of samples required are presented. A tabular identification of each analyte to be measured to support the safety classification, the analytical method to be used, the type of sample, the decision threshold for each analyte that would, if violated, place the tank on the safety issue watch list, and the assumed (desired) analytical uncertainty are provided. This is a living document that should be evaluated for updates on a semiannual basis. Evaluation areas consist of: identification of tanks that have been added or deleted from the specific safety issue watch lists, changes in primary and secondary decision variables, changes in decision rules used for the safety status classification, and changes in analytical requirements. This document directly supports all safety issue specific DQOs and additional characterization DQO efforts associated with pretreatment and retrieval. Additionally, information obtained during implementation can assist in resolving assumptions for revised safety strategies, and in addition, obtaining information which will support the determination of error tolerances, confidence levels, and optimization schemes for later revised safety strategy documentation.

Magnetic levitation system for moving objects  

DOE Patents (OSTI)

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

Hierarchical image segmentation for learning object priors  

Science Conference Proceedings (OSTI)

The proposed segmentation approach naturally combines experience based and image based information. The experience based information is obtained by training a classifier for each object class. For a given test image, the result of each classifier is represented as a probability map. The final segmentation is obtained with a hierarchial image segmentation algorithm that considers both the probability maps and the image features such as color and edge strength. We also utilize image region hierarchy to obtain not only local but also semi-global features as input to the classifiers. Moreover, to get robust probability maps, we take into account the region context information by averaging the probability maps over different levels of the hierarchical segmentation algorithm. The obtained segmentation results are superior to the state-of-the-art supervised image segmentation algorithms.

UFO: "Unidentified" Floating Object Driven by Thermocapillarity  

E-Print Network (OSTI)

In this fluid dynamics video, we show thermocapillary actuation of a binary drop of water and heptanol where the binary drop in motion takes on a UFO-like shape. On a parylene-coated silicon surface subjected to a linear temperature gradient, a pure heptanol droplet quickly moves to the cold side by the Marangoni stress, while a pure water droplet remains stuck due to a large contact angle hysteresis. When the water droplet was encapsulated by a thin layer of heptanol and thermally actuated, the binary droplet takes on a peculiar shape resembling an UFO, i.e. an "unidentified" floating object as the mechanism is not yet completely understood. Our finding suggests that pure liquid droplets (e.g. aqueous solutions) that are not conducive to thermocapillary actuation can be made so by encapsulating them with another judiciously chosen liquid (e.g. heptanol).

The Unusual Infrared Object HDF-N J123656.3+621322  

E-Print Network (OSTI)

We describe an object in the Hubble Deep Field North with very unusual near-infrared properties. It is readily visible in Hubble Space Telescope NICMOS images at 1.6um and from the ground at 2.2um, but is undetected (with signal-to-noise ~ 8.3 (97.7% confidence) from 1.6 to 1.1um. The object is compact but may be slightly resolved in the NICMOS 1.6um image. In a low-resolution, near-infrared spectrogram, we find a possible emission line at 1.643um, but a reobservation at higher spectral resolution failed to confirm the line, leaving its reality in doubt. We consider various hypotheses for the nature of this object. Its colors are unlike those of known galactic stars, except perhaps the most extreme carbon stars or Mira variables with thick circumstellar dust shells. It does not appear to be possible to explain its spectral energy distribution as that of a normal galaxy at any redshift without additional opacity from either dust or intergalactic neutral hydrogen. The colors can be matched by those of a dusty galaxy at z >~ 2, by a maximally old elliptical galaxy at z >~ 3 (perhaps with some additional reddening), or by an object at z >~ 10 whose optical and 1.1um light have been suppressed by the intergalactic medium. Under the latter hypothesis, if the luminosity results from stars and not an AGN, the object would resemble a classical, unobscured protogalaxy, with a star formation rate >~ 100 M_sun/yr. Such UV-bright objects are evidently rare at 2 < z < 12.5, however, with a space density several hundred times lower than that of present-day L* galaxies.

Reclaiming Storage in an Object Oriented Platform Supporting Extended C++ and Objective-C Applications  

E-Print Network (OSTI)

This paper describes the experience obtained from the conception and implementation of a system for garbage collection in the INESC Comandos platform. The garbage collector is presently being used not only by applications written in C++ but also in ObjectiveC (both with some minor restrictions) since both languages are supported by the platform. In order to reclaim the memory used by objects, two algorithms were implemented: stop and copy with multiple generations and an incremental mark and sweep. The generational copying algorithm reduces drastically the time used to reclaim old objects when compared with a nongenerational version. Besides these two algorithms, another one was developed in order to reclaim nonobject memory (usually strings). This memory can be explicitly created by the programmer or by the Communication Subsystem in order to support distributed invocations. 1 Introduction Comandos [1, 2] is a project within the ESPRIT (European Strategic Program for Research on Inf...

An Objective Climatology of Carolina Coastal Fronts  

E-Print Network (OSTI)

This study describes a simple objective method to identify cases of coastal frontogenesis offshore of the Carolinas and to characterize the sensible weather associated with frontal passage at measurement sites near the coast. The identification method, based on surface hourly data from offshore and adjacent land stations, was applied to an 11-yr dataset (1984–94). A total of 379 coastal fronts was found, 70 of which eventually made landfall along the North Carolina coast; 112 that remained offshore, and 197 were termed diurnal since they remained offshore but disappeared during daylight hours. Results show that most coastal and offshore sites experience a wind shift of about 40°–70 ° and a warming of about 2°–3°C during the hour of frontal passage. Exceptions include sites near colder waters where the rates are markedly reduced and frontal passage is often less discernible. Excluding diurnal fronts, just over half the cases were associated with cold-air damming (CAD) during the cold season of 16 October–15 April. Most of these winter cases linked with CAD were onshore fronts. During the warm season, most fronts were diurnal, but the association with CAD was still significant. To explore the synoptic-scale environment, composite maps for the cold season were generated for all three frontal subtypes from NCEP–NCAR reanalysis data. Results show a strong surface anticyclone

Climatic Change  

E-Print Network (OSTI)

Carbon dioxide (CO2) sequestration has been proposed as a key component in technological portfolios for managing anthropogenic climate change, since it may provide a faster and cheaper route to significant reductions in atmospheric CO2 concentrations than abating CO2 production. However, CO2 sequestration is not a perfect substitute for CO2 abatement because CO2 may leak back into the atmosphere (thus imposing future climate change impacts) and because CO2 sequestration requires energy (thus producing more CO2 and depleting fossil fuel resources earlier). Here we use analytical and numerical models to assess the economic efficiency of CO2 sequestration and analyze the optimal timing and extent of CO2 sequestration. The economic efficiency factor of CO2 sequestration can be expressed as the ratio of the marginal net benefits of sequestering CO2 and avoiding CO2 emissions. We derive an analytical solution for this efficiency factor for a simplified case in which we account for CO2 leakage, discounting, the additional fossil fuel requirement of CO2 sequestration, and the growth rate of carbon taxes. In this analytical model, the economic efficiency of CO2 sequestration decreases as the CO2 tax growth rate, leakage rates and energy requirements for CO2 sequestration increase.

Changing climate  

SciTech Connect

This article reviews a book written by a committee of the National Research Council. The book discussed the Greenhouse Effect which is a warming of the earth's atmosphere caused by the doubling of the atmospheric carbon dioxide concentration. The excess carbon dioxide is pollution derived from the burning of fossil fuels. The report suggested that the warming of the atmosphere would cause thawing of the polar regions which in turn would cause a rise in sea levels and flooding of the coastal lowlands. In addition to the flooding, the report predicted climate changes that would effect the productivity of croplands in the west. The authors of the report stressed that there was no way to avoid this warming of the earth. They suggested that people should start preparing for the inevitable.

MetaVM: A transparent distributed object system supported by runtime compiler  

E-Print Network (OSTI)

Abstract MetaVM is a distributed object system for Java virtual machine. It allows programmers to deal with remote objects in the same way they do local objects. Therefore, it can provide a single machine image to programmers. We implemented a runtime compiler of Java bytecode to provide the facilities. The runtime compiler generates a native code which can handle remote objects beyond the network besides the local objects. The compiler uses semantic expansion, which is a technique that changes the original semantics of a Java bytecode. This paper presents the simple programming interface, the code generation method of MetaVM, and our experimental performance results. The results demonstrate efficiency of remote operations. Keywords: distributed object system, network transparency, Java Just-In-Time compiler 1 Introduction A distributed object system is an instrument to develop a network distributed system in object-oriented programming languages. One of important benefits of such systems is to release programmers from the burden of exchanging information via a network. Programmers can write a distributed system in an object-oriented manner without concern for communication protocols.

Minkowski's Object: A Starburst Triggered by a Radio Jet, Revisited  

DOE Green Energy (OSTI)

We present neutral hydrogen, ultraviolet, optical and near-infrared imaging, as well as optical spectroscopic observations of Minkowski's Object (MO), a star forming system at the end of a radio jet associated with NGC541 at the center of a cluster of galaxies, Abell 194. The observations strengthen the evidence, first presented in 1985, that MO is a small, peculiar galaxy in which the star formation has been triggered by the radio jet. Key new results are the discovery of a double H I cloud with a mass of 4.9 x 10{sup 8} M{sub {circle_dot}} straddling the radio jet downstream from MO at the location where the jet changes direction and decollimates; a strong detection of MO at near- and far-UV wavelengths and in H{alpha}, both of which also show a double structure; and what appear to be numerous H II regions and associated clusters in MO. The UV morphology of MO along the radio jet resembles the radio-aligned, rest-frame UV morphologies seen in many high redshift radio galaxies, which are also thought to be caused by jet-induced star formation. The UV, optical, and near-IR data show that the stellar population is dominated by a 7.5Myr-old instantaneous burst, with a total stellar mass of 1.9 x 10{sup 7} M{sub {circle_dot}}.

Data Quality Objectives for Tank Farms Waste Compatibility Program  

SciTech Connect

There are 177 waste storage tanks containing over 210,000 m{sup 3} (55 million gal) of mixed waste at the Hanford Site. The River Protection Project (RPP) has adopted the data quality objective (DQO) process used by the U.S. Environmental Protection Agency (EPA) (EPA 1994a) and implemented by RPP internal procedure (Banning 1999a) to identify the information and data needed to address safety issues. This DQO document is based on several documents that provide the technical basis for inputs and decision/action levels used to develop the decision rules that evaluate the transfer of wastes. A number of these documents are presently in the process of being revised. This document will need to be revised if there are changes to the technical criteria in these supporting documents. This DQO process supports various documents, such as sampling and analysis plans and double-shell tank (DST) waste analysis plans. This document identifies the type, quality, and quantity of data needed to determine whether transfer of supernatant can be performed safely. The requirements in this document are designed to prevent the mixing of incompatible waste as defined in Washington Administrative Code (WAC) 173-303-040. Waste transfers which meet the requirements contained in this document and the Double-Shell Tank Waste Analysis Plan (Mulkey 1998) are considered to be compatible, and prevent the mixing of incompatible waste.

Extending Tcl for Dynamic Object-Oriented Programming  

E-Print Network (OSTI)

Object Tcl is an extension to the Tool Command Language (Tcl) for the management of complicated data types and dynamic object-oriented programming in general. We believe it is a worthy alternative to other object-oriented programming extensions (including [incr Tcl]) because it may be used dynamically, allows for per object specialization, has an economy of design and implementation, and provides a metaobject-based class system. Its design was driven by our VuSystem application needs to create a foundation with powerful abstraction and introspection capabilities, yet we sought to retain both the spirit and benefits of Tcl. This paper presents Object Tcl, emphasizing language design and implementation issues by comparing it with alternative systems. Keywords: object-oriented programming, Tcl, programming languages, [incr Tcl] 1 Introduction Object Tcl is an object-oriented extension to the Tool command Language (Tcl) [12] that we created to meet the programming needs...

The Object Space Approach: Decoupled Communication in C  

E-Print Network (OSTI)

We present the Object Space approach to distributed computation. Object Space allows for decoupled communication between program components by providing a shared data space of objects. This style of communication was inspired by Linda. The Object Space approach extends a sequential language (C++ in our case) with coordination and communication primitives. It integrates inheritance into associative addressing as known from Linda and facilitates passing of arbitrary objects between program components. Furthermore we introduce the notion of applicationspecific matching functions. A prototype for Object Space has been implemented in C++ under UNIX. A distributed phonebook and a scenario built around a time server and its clients serve as examples to demonstrate ideas and use of the concepts developed.

A new segmentation algorithm is derived, based on an object-background probability estimate exploiting the experimental fact that the statistics of local image derivatives show a Laplacian distribution. The objects' simply connectedness is included directly into the probability estimate and leads to an iterative optimization approach that can be implemented efficiently. This new approach avoids early thresholding, explicit edge detection, motion analysis, and grouping. Contribution type: Correspondence 1 This work was supported by the consortium VISAGE and KWF grant No. 2440.1 1 Introduction In many object recognition applications the objects of interest are moving whereas the background is static or can be stabilized [1, 2]. Motion segmentation can enormously simplify, subsequent object recognition steps. Therefore, detecting and segmenting moving objects in a static scene is an important computer vision task.

System and method for removal of buried objects  

DOE Patents (OSTI)

The present invention is a system and method for removal of buried objects. According to one embodiment of the invention, a crane with a vibrator casing driver is used to lift and suspend a large diameter steel casing over the buried object. Then the casing is driven into the ground by the vibratory driver until the casing surrounds the buried object. Then the open bottom of the casing is sealed shut by injecting grout into the ground within the casing near its bottom. When the seal has cured and hardened, the top of the casing is lifted to retrieve the casing, with the buried object inside, from the ground.

A system processes 2D images of 2D or 3D objects, creating a model of the object that is consistent with the image and as veridical as the perception of the 2D image by humans. Vertices of the object that are hidden in the image are recovered by using planarity and symmetry constraints. The 3D shape is recovered by maximizing 3D compactness of the recovered object and minimizing its surface area. In some embodiments, these two criteria are weighted by using the geometric mean.

Dynamic shape factors for hydox-generated plutonium dioxide-type non-sperical objects  

E-Print Network (OSTI)

The dynamic shape factors of HYDOX-generated plutonium dioxide-type non-spherical objects were estimated with computational methods. Leith's empirical methods were used to modify classical Stokes's law for aerosol dynamics (1987). The dynamic shape factor equations described by Leith were solved as functions of applicable curvilinear coordinates for objects resembling HYDOX-generated plutonium dioxide. Shapes modeled included six-sided hedron, right disk, oblate spheroid, and right-elliptical cone. Dynamic shape factors are plotted as a function of those curvilinear coordinates, within the full range of applicability. Experimental validity of the Leith dynamic shape factors ranged from 0.5 to 5 for each object modeled. This research is critical to determining settling velocities of HYDOX-generated plutonium dioxide aerosols. The change of particle size distribution over time and space can be derived, leading ultimately to an assessment of the dose from an unplanned release of plutonium dioxide.

BAKTRAK: Backtracking drifting objects using an iterative algorithm with a forward trajectory model  

E-Print Network (OSTI)

The task of determining the origin of a drifting object after it has been located is highly complex due to the uncertainties in drift properties and environmental forcing (wind, waves and surface currents). Usually the origin is inferred by running a trajectory model (stochastic or deterministic) in reverse. However, this approach has some severe drawbacks, most notably the fact that many drifting objects go through nonlinear state changes underway (e.g., evaporating oil or a capsizing lifeboat). This makes it difficult to naively construct a reverse-time trajectory model which realistically predicts the earliest possible time the object may have started drifting. We propose instead a different approach where the original (forward) trajectory model is kept unaltered while an iterative seeding and selection process allows us to retain only those particles that end up within a certain time-space radius of the observation. An iterative refinement process named BAKTRAK is employed where those trajectories that do...

BL Lacertae Objects and the Extragalactic Gamma-Ray Background  

E-Print Network (OSTI)

A tight correlation between gamma-ray and radio emission is found for a sample of BL Lacertae (BL Lac) objects detected by Fermi Gamma-ray Space Telescope (Fermi) and the Energetic Gamma-Ray Experiment Telescope (EGRET). The gamma-ray emission of BL Lac objects exhibits strong variability, and the detection rate of gamma-ray BL Lac objects is low, which may be related to the gamma-ray duty cycle of BL Lac objects. We estimate the gamma-ray duty cycle ~ 0.11, for BL Lac objects detected by EGRET and Fermi. Using the empirical relation of gamma-ray emission with radio emission and the estimated gamma-ray duty cycle, we derive the gamma-ray luminosity function (LF) of BL Lac objects from their radio LF. Our derived gamma-ray LF of BL Lac objects can almost reproduce that calculated with the recently released Fermi bright active galactic nuclei (AGN) sample. We find that about 45% of the extragalactic diffuse gamma-ray background (EGRB) is contributed by BL Lac objects. Combining the estimate of the quasar contri...

An Evaluation of Database Solutions to Spatial Object Association  

Science Conference Proceedings (OSTI)

Object association is a common problem encountered in many applications. Spatial object association, also referred to as crossmatch of spatial datasets, is the problem of identifying and comparing objects in two datasets based on their positions in a common spatial coordinate system--one of the datasets may correspond to a catalog of objects observed over time in a multi-dimensional domain; the other dataset may consist of objects observed in a snapshot of the domain at a time point. The use of database management systems to the solve the object association problem provides portability across different platforms and also greater flexibility. Increasing dataset sizes in today's applications, however, have made object association a data/compute-intensive problem that requires targeted optimizations for efficient execution. In this work, we investigate how database-based crossmatch algorithms can be deployed on different database system architectures and evaluate the deployments to understand the impact of architectural choices on crossmatch performance and associated trade-offs. We investigate the execution of two crossmatch algorithms on (1) a parallel database system with active disk style processing capabilities, (2) a high-throughput network database (MySQL Cluster), and (3) shared-nothing databases with replication. We have conducted our study in the context of a large-scale astronomy application with real use-case scenarios.

Object localization strategy for a mobile robot using RFID  

E-Print Network (OSTI)

One of the challenging issues in robotics is to give robots the ability to navigate itself in unknown environment without human help. In this thesis, we explored and evaluated object localization method for a mobile robot using radio-frequency identification (RFID) technology. The workplace included objects with RFID tags, a mobile robot with dual antenna RFID reader and obstacles: chairs, tables and a human. Using RFID reader, we were able to have the mobile robot communicate with the RFID tag to navigate the tagged object. This research employed the following methods for navigating a mobile robot and locating objects. First, a mobile robot was implemented as Braitenberg vehicle. It used the received signal strength of the RFID tag to compute instantaneously and produce movement of the wheel and generate suitable motion in order to navigate the object. Second, a mobile robot with directional antenna that collects data about relative direction of the interested RFID tag in its local coordinate system and computes tag positions by taking several measurements for different positions of the robot. Our experiment results showed that proposed RFID system can locate an object and can track the movement of a target object in real time. To verify effectiveness of the system we performed several experiments in the workplace.

Identifying Reference Objects by Hierarchical Clustering in Java Environment  

E-Print Network (OSTI)

Recently Java programming environment has become so popular. Java programming language is a language that is designed to be portable enough to be executed in wide range of computers ranging from cell phones to supercomputers. Computer programs written in Java are compiled into Java Byte code instructions that are suitable for execution by a Java Virtual Machine implementation. Java virtual Machine is commonly implemented in software by means of an interpreter for the Java Virtual Machine instruction set. As an object oriented language, Java utilizes the concept of objects. Our idea is to identify the candidate objects' references in a Java environment through hierarchical cluster analysis using reference stack and execution stack.

E-Print Network (OSTI)

Object-oriented programming laws have been proposed in the context of languages that are not combined with a behavioral interface specification language (BISL). The strong dependence between source-code and interface specifications may cause a number of difficulties when transforming programs. In this paper we introduce a set of programming laws for object-oriented languages like Java combined with the Java Modeling Language (JML). The set of laws deals with object-oriented features taking into account their specifications. Some laws deal only with features of the specification language. These laws constitute a set of small transformations for the development of more elaborate ones like refactorings.

Object-Oriented Implementation for NAS Parallel Benchmarks  

E-Print Network (OSTI)

ion deals with the external behavior of an object while encapsulation helps manage the system complexity by hiding the internal details of the object implementation. Thus, the abstraction and encapsulation complement each other in dealing with the complexity. Often, a set of abstractions in real life systems forms a hierarchy. Inheritance organizes the classes in a hierarchical structure, which gives a greater level of abstraction to the problem. Inheritance coupled with dynamic binding results in polymorphism, where one name can be used to denote different items of the classes in a hierarchy. This very organized approach of the object--oriented paradigm helps the developer in conquering the complexity of highly complex scientific applications (Booch 1991). The need for proper abstractions is more crucial for parallel programming than sequential programming (Grimshaw 1993). The higher 47 level abstractions provided by the object--oriented paradigm can make the specific architectural ...

Specifying and Adapting Object Behavior during System Evolution  

E-Print Network (OSTI)

Object-Oriented software engineering must address new issues during system evolution, namely the effects of class evolution on existing class methods. A Class Dictionary Graph describes the class structure and relationships of a given domain. A Propagation Pattern defines object behavior by describing responsibilities among a group of collaborating classes. The behavior described in a Propagation Pattern is mapped onto the class structure defined in a Class Dictionary Graph, and the appropriate C++ code is generated. Class structures evolve in many ways. This paper details the effects of class evolution on the object behavior defined in existing Propagation Patterns, and describes the requirements for adapting Propagation Patterns during class evolution, as compared to the efforts of maintaining C++ code.

In-place Annotation of Physical Objects with Pico- Projectors  

E-Print Network (OSTI)

Just as we annotate digital documents with digital annotations for collaborative work, we frequently annotate physical objects using physical annotations (e.g. by using Post-It notes). In the physical world, we are limited by the size of the physical Post-It note, and further, too many Post-It notes clutter the physical space. In this work, we explore the use of handheld projectors combined with a tablet to create digital annotations for physical objects, and to visualize these annotations around such physical objects. Our design allows people to use a flashlight metaphor for visualizing digital “post-it ” notes, which can be created in-place by pointing the projector at an object, and then adding the annotation using the tablet. We realized this design in a prototype to informally assess the effectiveness of the metaphors we used, and to gather suggestions for future work in this area.

High Energy Gamma Rays from Protons Hitting Compact Objects  

E-Print Network (OSTI)

In a previous paper the spectrum of positrons produced by matter initially at rest falling onto a massive compact object was calculated. In this paper this calculation is generalized to obtain both the spectrum of in-flight positron annihilation and pi0 decay gamma rays produced when protons with a cosmic ray-like spectrum hit the surface. The resulting pi0 decay gamma ray spectrum reflects the high energy proton energy spectrum, and is largely independent of the mass of the compact object. One notable prediction for all compact objects is a dip in the spectrum below 70 MeV. As applied to the 10^6 solar mass massive compact object near to the center of our galaxy, our theory shows promise for explaining the gamma rays coming from the galactic center as observed by both the Compton satellite and HESS ground based array.

An object-oriented implementation of the Xpress Transfer Protocol  

SciTech Connect

Object-oriented design principles map well onto protocol implementations because protocols essentially manipulate two structures - packets and the states of the endpoints. In this paper the authors describe an implementation of the Xpress Transfer Protocol as a user space daemon written in C++. The object-oriented model forces the programmer to properly place functionality and information ownership. The model facilitates porting to various platforms and greatly eases the task of building data delivery services.

Technique for identifying, tracing, or tracking objects in image data  

SciTech Connect

A technique for computer vision uses a polygon contour to trace an object. The technique includes rendering a polygon contour superimposed over a first frame of image data. The polygon contour is iteratively refined to more accurately trace the object within the first frame after each iteration. The refinement includes computing image energies along lengths of contour lines of the polygon contour and adjusting positions of the contour lines based at least in part on the image energies.

A Generic XML Language for Characterising Objects to Support Digital Preservation  

E-Print Network (OSTI)

The dominance of digital objects in today’s information landscape has changed the way humankind creates and exchanges information. However, it has also brought an entirely new problem: the longevity of digital objects. Due to the fast changes in technologies, digital documents have a short lifespan before they become obsolete. Digital preservation, i.e. actions to ensure longevity of digital information, thus has become a pressing challenge. Different strategies such as migration and emulation have been proposed; however, the decision between available tools for format migration is very complex. Preservation planning supports decision makers in reaching accountable decisions by evaluating potential strategies against well-defined requirements. Especially the evaluation of different migration tools for digital preservation has to rely on validating the converted objects and thus on an analysis of the logical structure and the content of documents. This paper presents the eXtensible Characterisation Languages (XCL) that support the automatic validation of document conversions and the evaluation of migration quality by hierarchically decomposing a document and XML language. We present the context of the development of these languages and tools and describe the overall concept and features of the languages and how they can be applied to the evaluation of digital preservation solutions.

One User's Report on Sandia Data Objects: Evaluation of the DOL and PMO for use in Future  

SciTech Connect

The Feature Characterization project (FCDMF) has the goal of building tools that can extract and analyze coherent features in a terabyte dataset. We desire to extend our feature characterization library (FClib) to support a wider variety of complex ASCI data, and to support parallel algorithms. An attractive alternative to extending the library's internal data structures is to replace them with an externally provided data object. This report is the summary of a quick exploration of two candidate data objects in use at Sandia National Laboratories: the Data Object Library (DOL) and the Parallel Mesh Object (PMO). It is our hope that this report will provide information for potential users of the data objects, as well as feedback for the objects' developers. The data objects were evaluated as to whether they (1) supported the same capabilities as the current version of FClib, (2) provided additional required capabilities, and (3) were relatively easy to use. Both data objects met the requirements of having the same capabilities as FClib and support for parallel algorithms. However, the DOL has a richer set of data structures that more closely align with the current data structures of FClib and our planned extensions. Specifically, the DOL can support time changing geometry, which is needed to represent features as datasets. Unfortunately, the DOL did not meet our ease of use requirement. The PMO was easier to learn and use, but did not support time-changing geometry. Given the above results, we will extend the FClib API (Application Programming Interface) to handle time-changing geometry. Then we will replace the internal data structures with the DOL, but we will provide the FClib API in addition to the DOL API to support simplified usage.

Keck Pencil-Beam Survey for Faint Kuiper Belt Objects  

E-Print Network (OSTI)

We present the results of a pencil-beam survey of the Kuiper Belt using the Keck 10-m telescope. A single 0.01 square degree field is imaged 29 times for a total integration time of 4.8 hr. Combining exposures in software allows the detection of Kuiper Belt Objects (KBOs) having visual magnitude V < 27.9. Two new KBOs are discovered. One object having V = 25.5 lies at a probable heliocentric distance d = 33 AU. The second object at V = 27.2 is located at d = 44 AU. Both KBOs have diameters of about 50 km, assuming comet-like albedos of 4%. Data from all surveys are pooled to construct the luminosity function from red magnitude R = 20 to 27. The cumulative number of objects per square degree, N (< R), is fitted to a power law of the form log_(10) N = 0.52 (R - 23.5). Differences between power laws reported in the literature are due mainly to which survey data are incorporated, and not to the method of fitting. The luminosity function is consistent with a power-law size distribution for objects having dia...

Nonlinear Connections and Description of Photon-like Objects

The idea is based on consideration of {\\it nonintegrable} subdistributions of some appropriate completely integrable distribution (differential system) on a manifold and then to make use of the corresponding curvatures as generators of measures of interaction, i.e. of energy-momentum exchange among the physical subsystems mathematically represented by the nonintegrable subdistributions. The concept of photon-like object is introduced and description of such objects in these terms is given.

We also propose a set of design and implementation techniques based on modern objectoriented methods, which reconcile the reusability and flexibility of object-oriented software with the required efficiency of deeply embedded systems. 1 Introduction Most of today's computer systems are more or less hidden in embedded applications like mobile phones or cars. Even some kitchen aids have their own processors. More and more application areas are "computerized". In many if not most of them only very limited computational power is available. These so called "deeply" embedded systems are a great challenge for today's software producers. In contrast to PCs the various constraints like cost reduction,...

Clustering of Meter-wave Luminous Objects toward Monoceros  

E-Print Network (OSTI)

A distribution of the meter-wave luminous objects, which are bright at frequency 74 MHz (a wavelength of 4 m) but not detectable at 1.4 GHz (21 cm) in the VLA surveys, shows a notable concentration in a scale of a few degrees toward Monoceros [(l, b)=(225, 4)]. We argue that it is a part of giant radio relics associated with a nearby cluster of galaxies with cz~2400$ km s^{-1} centered on the spiral galaxy NGC 2377. The angular separation of these objects from the clustering center is consistent with the separation of distant relics to the cluster center if scaled by distance. This fact implies that the concentrations of meter-wave luminous objects can be used as a tracer of the structure of the Local Supercluster and it's vicinity.

Orbit determination of space objects based on sparse optical data  

E-Print Network (OSTI)

While building up a catalog of Earth orbiting objects, if the available optical observations are sparse, not deliberate follow ups of specific objects, no orbit determination is possible without previous correlation of observations obtained at different times. This correlation step is the most computationally intensive, and becomes more and more difficult as the number of objects to be discovered increases. In this paper we tested two different algorithms (and the related prototype software) recently developed to solve the correlation problem for objects in geostationary orbit (GEO), including the accurate orbit determination by full least squares solutions with all six orbital elements. Because of the presence in the GEO region of a significant subpopulation of high area to mass objects, strongly affected by non-gravitational perturbations, it was actually necessary to solve also for dynamical parameters describing these effects, that is to fit between 6 and 8 free parameters for each orbit. The validation was based upon a set of real data, acquired from the ESA Space Debris Telescope (ESASDT) at the Teide observatory (Canary Islands). We proved that it is possible to assemble a set of sparse observations into a set of objects with orbits, starting from a sparse time distribution of observations, which would be compatible with a survey capable of covering the region of interest in the sky just once per night. This could result in a significant reduction of the requirements for a future telescope network, with respect to what would have been required with the previously known algorithm for correlation and orbit determination.

Parallelization of an Object-Oriented Unstructured Aeroacoustics Solver  

E-Print Network (OSTI)

A computational aeroacoustics code based on the discontinuous Galerkin method is ported to several parallel platforms using MPI. The discontinuous Galerkin method is a compact high-order method that retains its accuracy and robustness on non-smooth unstructured meshes. In its semi-discrete form, the discontinuous Galerkin method can be combined with explicit time marching methods making it well suited to time accurate computations. The compact nature of the discontinuous Galerkin method also makes it well suited for distributed memory parallel platforms. The original serial code was written using an objectoriented approach and was previously optimized for cache-based machines. The port to parallel platforms was achieved simply by treating partition boundaries as a type of boundary condition. Code modifications were minimal because boundary conditions were abstractions in the original program. Scalability results are presented for the SGI Origin, IBM SP2, and clusters of SGI and Sun workstations. Slightly superlinear speedup is achieved on a fixed-size problem on the Origin, due to cache effects.

A Cyclic Distributed Garbage Collector for Network Objects  

E-Print Network (OSTI)

Abstract. This paper presents an algorithm for distributed garbage collection and outlines its implementation within the Network Objects system. The algorithm is based on a reference listing scheme, which is augmented by partial tracing in order to collect distributed garbage cycles. Processes may be dynamically organised into groups, according to appropriate heuristics, to reclaim distributed garbage cycles. The algorithm places no overhead on local collectors and suspends local mutators only brie y. Partial tracing of the distributed graph involves only objects thought to be part of a garbage cycle: no collaboration with other processes is required. The algorithm o ers considerable exibility, allowing expediency and fault-tolerance to be traded against completeness.

Unsupervised Segmentation of Object Shadow and Highlight Using Statistical Snakes  

E-Print Network (OSTI)

This paper deals with the detection and analysis of objects in side-scan sonar images for target identifi cation. The initial step for any identification is a good segmentation of the scene and a reliable extraction of the shadow of the object. The literature reports various techniques for detecting the shadow of objects on the seabed, the most popular of which is based on the use of Markov Random Field (MRF) models. We introduce in this paper, a new technique based on a statistical snake to perform this operation. This technique relies on the modeling of the shadow and non-shadow regions as probability density models expressed as exponential laws (Gaussian, Rayleigh, Poisson,..) which are well suited to the physics of sonar sensing. The algorithm determines the snake shape that optimally separates the scene into regions described by the same probability density function utilising a Monte Carlo Markov Chain (MCMC) method to drive the snake. Moreover, as in classical snake techniques, the shape can be constrained via an intrinsic energy term enabling a model-based search for man-made objects in the image. The problems introduced by directional seabeds are discussed and the use of directional filters to extract further information investigated. This

Bayesian Classification of Astronomical Objects -- and what is behind it  

E-Print Network (OSTI)

We present a Bayesian method for the identification and classification of objects from sets of astronomical catalogs, given a predefined classification scheme. Identification refers here to the association of entries in different catalogs to a single object, and classification refers to the matching of the associated data set to a model selected from a set of parametrized models of different complexity. By the virtue of Bayes' theorem, we can combine both tasks in an efficient way, which allows a largely automated and still reliable way to generate classified astronomical catalogs. A problem to the Bayesian approach is hereby the handling of exceptions, for which no likelihoods can be specified. We present and discuss a simple and practical solution to this problem, emphasizing the role of the "evidence" term in Bayes' theorem for the identification of exceptions. Comparing the practice and logic of Bayesian classification to Bayesian inference, we finally note some interesting links to concepts of the philos...

As a means of detecting compact ultra dense objects (CUDOs) with nuclear density or greater, and a mass $10^{-10}solar system bodies. We find that a heavy enough CUDO pulverizes, heats and entrains material in a small cylinder around its trajectory through the target body. Because the resulting impact features endure for geologic timescales, data is accumulated over the history of the solar system. Exclusion of all CUDO impact signatures would set a strong limit on their local abundance.

Many recent efforts to integrate transportation and deployment simulations, although beneficial, have lacked a feature vital for seamless integration: a common data class representation. It is an objective of the Department of Defense (DoD) to standardize all classes used in object-oriented deployment simulations by developing a standard class attribute representation and behavior for all deployment simulations that rely on an underlying class representation. The Extensive Hierarchy and Object Representation for Transportation Simulations (EXHORT) is a collection of three hierarchies that together will constitute a standard and consistent class attribute representation and behavior that could be used directly by a large set of deployment simulations. The first hierarchy is the Transportation Class Hierarchy (TCH), which describes a significant portion of the defense transportation system; the other two deal with infrastructure and resource classes. EXHORT will allow deployment simulations to use the same set of underlying class data, ensure transparent exchanges, reduce the effort needed to integrate simulations, and permit a detailed analysis of the defense transportation system. This paper describes EXHORT's first hierarchy, the TCH, and provides a rationale for why it is a helpful tool for modeling major portions of the defense transportation system.

Detection of Small Kuiper Belt Objects by Stellar Occultations  

E-Print Network (OSTI)

Knowledge of the Kuiper Belt is currently limited to those objects that can be detected directly. Objects with diameters less than $\\sim$10km reflect too little light to be detected. These smaller bodies could contain most of the mass in the Kuiper Belt while the abundance of these bodies may constrain the distribution of mass. The overall size distribution of bodies within the Kuiper Belt can also be inferred from the relative abundances of sub-km and larger bodies. Stellar occultations are already used to study dark objects in the Solar System, such as asteroids or planetary rings. Occultation by a KBO of a size comparable to, or larger than, that of the Fresnel Scale will result in Fresnel diffraction. Detection of diffraction effects requires fast multiple-star photometry, which will be conducted in July 2007 using the Orthogonal Parallel Transfer Imaging Camera (OPTIC) mounted on the University of Hawaii 2.2m telescope on Mauna Kea. This paper details how knowledge of the mass and structure of the outer Solar System may be obtained through the detection of serendipitous stellar occultations.

HST Imaging of the BL Lacertae Object OJ 287  

E-Print Network (OSTI)

Hubble Space Telescope WFPC-2 I-band (F814W) images of the BL Lacertae object OJ 287 and the surrounding field are presented. We find evidence of associated extended nebulosity near OJ 287, as well as a small nebulosity to the West, which may be spatially coincident with the position of previously observed radio emission. The brightness of a host galaxy is difficult to determine due to the brightness of the active nucleus, but it lies in the range -21.5 > M_R > -23.1 (H_0 = 100 km s^{-1} Mpc^{-1}, q_0 = 0). No evidence is seen for the previously reported optical ``jet'' at position angle 220 degrees to a surface brightness limit of I = 24.3 mag arcsec^{-2}. There are several resolved and unresolved objects within 17'' of OJ~287 in the field to limits of I=25 (point source 5\\sigma detections). The magnitudes and relative positions of these objects are reported. An offset in the centroid position between the OJ 287 point source and the underlying nebulosity reported by Wurtz, Stocke and Yee is confirmed and measured to be about 0.4 (1.2h^{-1} kpc at the redshift of OJ~287). This offset is tentatively interpreted as evidence for recent merger activity rather than a sign of gravitational microlensing.

From OO to FPGA : fitting round objects into square hardware.  

SciTech Connect

Consumer electronics today such as cell phones often have one or more low-power FPGAs to assist with energy-intensive operations in order to reduce overall energy consumption and increase battery life. However, current techniques for programming FPGAs require people to be specially trained to do so. Ideally, software engineers can more readily take advantage of the benefits FPGAs offer by being able to program them using their existing skills, a common one being object-oriented programming. However, traditional techniques for compiling object-oriented languages are at odds with today's FPGA tools, which support neither pointers nor complex data structures. Open until now is the problem of compiling an object-oriented language to an FPGA in a way that harnesses this potential for huge energy savings. In this paper, we present a new compilation technique that feeds into an existing FPGA tool chain and produces FPGAs with up to almost an order of magnitude in energy savings compared to a low-power microprocessor while still retaining comparable performance and area usage.

Analysis of Star Formation in Galaxy-like Objects  

E-Print Network (OSTI)

Using cosmological hydrodynamical simulations, we investigate the effects of hierarchical aggregation on the triggering of star formation in galactic-like objects. We include a simple star formation model to transform the cold gas in dense regions into stars. Simulations with different parameters have been performed in order to quantify the dependence of the results on the parameters. We then resort to stellar population synthesis models to trace the color evolution of each object with red-shift and in relation to their merger histories. We find that, in a hierarchical clustering scenario, the process of assembling of the structure is one natural mechanism that may trigger star formation. The resulting star formation rate history for each individual galactic object is composed of a continuous one ($\\leq 3 \\rm{M_{\\odot}/yr}$) and a series of star bursts. We find that even the accretion of a small satellite can be correlated with a stellar burst. Massive mergers are found to be more efficient at transforming gas into stars

Integrating implicit answers with object-oriented queries  

E-Print Network (OSTI)

Queries in object-oriented datab;Lqcs are formulated against a class and retrieve instnnccls of the class sat,is-fying a certain predicate on the att,riblltes of the class. The presence of a class hierarchy, an integral part of any object-oriented data model, allows answers to be expressed implicitly in terms of classes and instances. This enables answers to be provided at different levels of abstraction. Shum and Muntz [SM88] presented a way of providing implicit expressions based on a taxonomy defined over the database. The algorithm presented in [SM88] is optimal in the length of the answer but the clarity of the answer is often poor. In this paper, the fo-cus is on coherent answers: implicit answers that are not necessarily optimal in the number of terms but are easy to comprehend. We show that a uniqlle coherent answer can be obtained efficiently in a top down nlanncr. Since the objective is to provide cohcrcnt, answers, and user queries are formulated by means of query operators to access the database, the standard query operators are redefined to obtain and manipulate coherent answers. Coherent answers are useful in coping with information complexity as they allow answers to be represented ab-stractly and are also a useful rctprescntation tool for complex information systems. 1

Geothermal Program Review VI: proceedings. Beyond goals and objectives  

DOE Green Energy (OSTI)

Program Review VI was comprised of six sessions, including an opening session, four technical sessions that addressed each of the major DOE research areas, and a session on special issues. The technical sessions were on Hydrothermal, Hot Dry Rock, Geopressured and Magma resources. Presenters in the technical sessions discussed their R and D activities within the context of specific GTD Programmatic Objectives for that technology, their progress toward achieving those objectives, and the value of those achievements to industry. The ''Special Issues'' presentations addressed several topics such as the interactions between government and industry on geothermal energy R and D; the origin and basis for the programmatic objectives analytical computer model; and international marketing opportunities for US geothermal equipment and services. The unique aspect of Program Review VI was that it was held in conjunction with the National Geothermal Association's Industry Round Table on Federal R and D. The Round Table provided a forum for open and lively discussions between industry and government researchers and gave industry an opportunity to convey their needs and perspectives on DOE's research programs. These discussions also provided valuable information to DOE regarding industry's priorities and directions.

The Inevitable Stability of Software Change  

E-Print Network (OSTI)

Real software systems change and become more complex over time. But which parts change and which parts remain stable? Common wisdom, for example, states that in a well-designed object-oriented system, the more popular a class is, the less likely it is to change from one version to the next, since changes to this class are likely to impact its clients. We have studied consecutive releases of several public domain, object-oriented software systems and analyzed a number of measures indicative of size, popularity, and complexity of classes and interfaces. As it turns out, the distributions of these measures are remarkably stable as an application evolves. The distribution of class size and complexity retains its shape over time. Relatively little code is modified over time. Classes that tend to be modified, however, are also the more popular ones, that is, those with greater Fan-In. In general, the more “complex ” a class or interface becomes, the more likely it is to change from one version to the next. 1.

Method For Detecting The Presence Of A Ferromagnetic Object  

SciTech Connect

A method for detecting a presence or an absence of a ferromagnetic object within a sensing area may comprise the steps of sensing, during a sample time, a magnetic field adjacent the sensing area; producing surveillance data representative of the sensed magnetic field; determining an absolute value difference between a maximum datum and a minimum datum comprising the surveillance data; and determining whether the absolute value difference has a positive or negative sign. The absolute value difference and the corresponding positive or negative sign thereof forms a representative surveillance datum that is indicative of the presence or absence in the sensing area of the ferromagnetic material.

Mastery of sixth grade TEKS objectives through integrated learning  

E-Print Network (OSTI)

The purpose of this study was to assess learning in sixth grade students? by gain scores in science and mathematics while participating in the integrative curriculum modules developed by the Partnership for Environmental Education and Rural Health (PEER) Program. The PEER Program is a collaboration between the College of Education and Applied Sciences, and the College of Veterinary Medicine at Texas A&M University. Two Integrated Curricular Modules provided the experimental treatment in this study. The alliance of the PEER Program and Texas A&M University has developed a middle school integrated curriculum based on sixth grade mathematics, science, English, reading and social studies TEKS (Texas Essential Knowledge and Skills)-based objectives. This multimedia curriculum incorporates the five disciplines into an adventure narrative featuring characters similar in dynamics to its targeted population, with problem-solving activities aimed to spark learning interests of students and emphasize skill development. Integrated learning allows students an alternative method to traditional or conventional ways of learning by conceptualizing the subject matter into more than one medium. Selected students who participated in this study were pre-tested with Texas Assessment of Knowledge and Skills (TAKS)-related instrumentation based on TEKS objectives. Their scores were recorded and some students were then selected to participate as the treatment group where they were taught the PEER Program?s integrated curriculum, patterned to correspond to TEKS? objectives. Post-tests were administered to both groups, and gain scores were collected to evaluate and determine if there was evidence that the PEER Program was successful in improving the mastery of the TEKS objectives in mathematics and science. Results varied in this study with findings that supported the notions that the integrated PEER experimental modules had a positive, negative, and no effect on the experimental populations compared to the control, or untreated population. It is inconclusive to whether the integrated modules were effective in raising and improving test scores based on the preparatory curriculum. Inconsistencies in the results from this study imply that further research is needed.

Gamma-Ray Bursts from Primordial Quark Objects in Space  

E-Print Network (OSTI)

We investigate the possibility that gamma-ray bursts originate in a concentric spherical shell with a given average redshift and find that this is indeed compatible with the data from the third BATSE (3B) catalog. It is also shown that there is enough freedom in the choice of unknown burst properties to allow even for extremely large distances to the majority of bursts. Therefore, we speculate about an early, and very energetic, origin of bursts, and suggest that they come from phase transitions in massive objects of pure quark matter, left over from the Big Bang.

An approach to object-orientation in action systems  

E-Print Network (OSTI)

We extend the action system formalism with a notion of objects that can be active and distributed. With this extension we can model class-based systems as action systems. Moreover, as the introduced constructs can be translated into ordinary action systems, we can use the theory developed for action systems, especially the refinement calculus, even for class-based systems. We show how inheritance can be modelled in different ways via class refinement. Re ning a class with an other class within the refinement calculus ensures that the original behavior of the class is maintained throughout the refinements. Finally, weshowhow to reuse proofs and entire class modules in a refinement step.

Objectives and strategies of the International Photovoltaic Program Plan  

SciTech Connect

The Solar Photovoltaic Energy Research, Development, and Demonstration (RD and D) Act of 1978 calls for the Secretary of the US Department of Energy (DOE) to prepare a plan to demonstrate photovoltaic systems in other nations and to facilitate the widespread use of these systems. The objective of the International Photovoltaic Program Plan, the strategies that will be used in the plan, and the approach that is being taken to prepare the plan are described. Background on photovoltaic technology and markets and the DOE domestic photovoltaic effort is also provided. The International Photovoltaic Program Plan will complement the DOE domestic activities to stimulate international markets. A number of national and international benefits could result if the objective of accelerating the widespread use of photovoltaic systems in international markets is realized. A primary benefit is that foreign markets may help stabilize the US photovoltaic industry and foster its expansion. Other benefits include contributions to the advancement of developing countries, reductions in world oil imports, and improvements in the US balance of trade. Strategies to be addressed in the plan are photovoltaic system demonstrations, systems development, information gathering and dissemination, financial incentives, and administrative actions. A critical aspect of the plan will be the coordination of selected programs and the monitoring and assessment of the plan's results. Analyses of international markets, international financial institutions, foreign competition, international marketing experiences of other US industries, and system development needs have been initiated to support the plan.

Short paper: 3-Hand Manipulation of Virtual Objects  

E-Print Network (OSTI)

In this paper we introduce a new 3D interaction technique called “3-Hand Manipulation”, for multi-user collaborative manipulation of 3D objects. The 3-Hand Manipulation relies on the use of three manipulation points that can be used simultaneously by three different “hands ” of two or three users. Interestingly, the three translation motions of the manipulation points can fully determine the resulting 6 degrees of freedom motion of the manipulated object. We describe the implementation of the 3-Hand Manipulation, its graphical representations and an illustration of its use by two or three users on an insertion task in immersive virtual environment. This technique could be used in various applications of collaborative VR such as for virtual prototyping, training simulations, assembly and maintenance simulations.

Positron emission mammography (PEM): Effect of activity concentration, object size, and object contrast on phantom lesion detection  

Science Conference Proceedings (OSTI)

Purpose: To characterize the relationship between lesion detection sensitivity and injected activity as a function of lesion size and contrast on the PEM (positron emission mammography) Flex Solo II scanner using phantom experiments. Methods: Phantom lesions (spheres 4, 8, 12, 16, and 20 mm diameter) were randomly located in uniform background. Sphere activity concentrations were 3 to 21 times the background activity concentration (BGc). BGc was a surrogate for injected activity; BGc ranged from 0.44-4.1 kBq/mL, corresponding to 46-400 MBq injections. Seven radiologists read 108 images containing zero, one, or two spheres. Readers used a 5-point confidence scale to score the presence of spheres. Results: Sensitivity was 100% for lesions {>=}12 mm under all conditions except for one 12 mm sphere with the lowest contrast and lowest BGc (60% sensitivity). Sensitivity was 100% for 8 mm spheres when either contrast or BGc was high, and 100% for 4 mm spheres only when both contrast and BGc were highest. Sphere contrast recovery coefficients (CRC) were 49%, 34%, 26%, 14%, and 2.8% for the largest to smallest spheres. Cumulative specificity was 98%. Conclusions: Phantom lesion detection sensitivity depends more on sphere size and contrast than on BGc. Detection sensitivity remained {>=}90% for injected activities as low as 100 MBq, for lesions {>=}8 mm. Low CRC in 4 mm objects results in moderate detection sensitivity even for 400 MBq injected activity, making it impractical to optimize injected activity for such lesions. Low CRC indicates that when lesions <8 mm are observed on PEM images they are highly tracer avid with greater potential of clinical significance. High specificity (98%) suggests that image statistical noise does not lead to false positive findings. These results apply to the 85 mm thick object used to obtain them; lesion detectability should be better (worse) for thinner (thicker) objects based on the reduced (increased) influence of photon attenuation.

Objectives, Strategies, and Challenges for the Advanced Fuel Cycle Initiative  

Science Conference Proceedings (OSTI)

This paper will summarize the objectives, strategies, and key chemical separation challenges for the Advanced Fuel Cycle Initiative (AFCI). The major objectives are as follows: Waste management - defer the need for a second geologic repository for a century or more, Proliferation resistance - be more resistant than the existing PUREX separation technology or uranium enrichment, Energy sustainability - turn waste management liabilities into energy source assets to ensure that uranium ore resources do not become a constraint on nuclear power, and Systematic, safe, and economic management of the entire fuel cycle. There are four major strategies for the disposal of civilian spent fuel: Once-through - direct disposal of all discharged nuclear fuel, Limited recycle - recycle transuranic elements once and then direct disposal, Continuous recycle - recycle transuranic elements repeatedly, and Sustained recycle - same as continuous except previously discarded depleted uranium is also recycled. The key chemical separation challenges stem from the fact that the components of spent nuclear fuel vary greatly in their influence on achieving program objectives. Most options separate uranium to reduce the weight and volume of waste and the number and cost of waste packages that require geologic disposal. Separated uranium can also be used as reactor fuel. Most options provide means to recycle transuranic (TRU) elements - plutonium (Pu), neptunium (Np), americium (Am), curium (Cm). Plutonium must be recycled to obtain repository, proliferation, and energy recovery benefits. U.S. non-proliferation policy forbids separation of plutonium by itself; therefore, one or more of the other transuranic elements must be kept with the plutonium; neptunium is considered the easiest option. Recycling neptunium also provides repository benefits. Americium recycling is also required to obtain repository benefits. At the present time, curium recycle provides relatively little benefit; indeed, recycling curium in thermal reactors would significantly increase the hazard (hence cost) of the resulting fuel. Most options separate short-lived fission products cesium and strontium to allow them to decay in separate storage facilities tailored to that need, rather than complicate long-term geologic disposal. This can also reduce the number and cost of waste packages requiring geologic disposal. These savings are balanced by costs for separation and recycle systems. Several long-lived fission products, such as technetium-99 and iodine-129 go to geologic disposal in improved waste forms, recognizing that transmutation of these isotopes would be a slow process; however, the program has not precluded their transmutation as a future alternative.

Ownership transfer for non-federate object and time management in developing an hla compliant logistics model.  

Science Conference Proceedings (OSTI)

A seaport simulation model, PORTSIM, has been developed for the Department of Defense (DOD) at Argonne National Laboratory. PORTSIM simulates the detailed processes of cargo loading and unloading in a seaport and provides throughput capability, resource utilization, and other important information on the bottlenecks in a seaport operation, which are crucial data in determining troop and equipment deployment capability. There are two key problems to solve in developing the HLA-compliant PORTSIM model. The first is the cargo object ownership transfer problem. In PORTSIM, cargo items, e.g. vehicles, containers, and pallets, are objects having asset attributes. Cargo comes to a seaport for loading or unloading. The ownership of a cargo object transfers from its carrier to the port and then from the port to a new carrier. Each owner of the cargo object is responsible for publishing and updating the attributes of the cargo object when it has the ownership. This creates a unique situation in developing the PORTSIM federate object model, that is, the ownership of the object instead of the attributes needs to be changed in handling the cargo object in the PORTSIM federate. The ownership management service provided by the current RTI does not directly address this issue. The second is the time management issue. PORTSIM is an event-driven simulation that models seaport operations over time. To make PORTSIM HLA compliant, time management must be addressed to allow for synchronization with other simulation models. This paper attempts to address these two issues and methodologies developed for solving these two problems.

NMIS is a time-dependent coincidence counting system that is used to characterize both fissile and non-fissile materials undergoing nondestructive assay. NMIS characterizes materials by interrogating them with neutrons, either from an associated-particle deuterium-tritium (DT) neutron generator, which produces a time and directionally tagged monoenergetic beam of 14.1 MeV neutrons, or a time-tagged spontaneous fission source in an ionization chamber.

The objectives for deep scientific drilling in Yellowstone National Park  

DOE Green Energy (OSTI)

The western area of the United Stated contains three young silicic calderas, all of which contain attractive targets for scientific drilling. Of the three, the Yellowstone caldera complex is the largest, has the most intense geothermal anomalies, and is the most seismically active. On the basis of scientific objectives alone. it is easily the first choice for investigating active hydrothermal processes. This report briefly reviews what is known about the geology of Yellowstone National Park and highlights unique information that could be acquired by research drilling only in Yellowstone. However, it is not the purpose of this report to recommend specific drill sites or to put forth a specific drilling proposal. 175 refs., 9 figs., 2 tabs.

Systems for detecting charged particles in object inspection  

DOE Patents (OSTI)

Techniques, apparatus and systems for detecting particles such as muons. In one implementation, a monitoring system has a cosmic ray-produced charged particle tracker with a plurality of drift cells. The drift cells, which can be for example aluminum drift tubes, can be arranged at least above and below a volume to be scanned to thereby track incoming and outgoing charged particles, such as cosmic ray-produced muons, while also detecting gamma rays. The system can selectively detect devices or materials, such as iron, lead, gold and/or tungsten, occupying the volume from multiple scattering of the charged particles passing through the volume and can also detect any radioactive sources occupying the volume from gamma rays emitted therefrom. If necessary, the drift tubes can be sealed to eliminate the need for a gas handling system. The system can be employed to inspect occupied vehicles at border crossings for nuclear threat objects.

Method for detecting an image of an object  

DOE Patents (OSTI)

A method for detecting an absorption, refraction and scatter image of an object by independently analyzing, detecting, digitizing, and combining images acquired on a high and a low angle side of a rocking curve of a crystal analyzer. An x-ray beam which is generated by any suitable conventional apparatus can be irradiated upon either a Bragg type crystal analyzer or a Laue type crystal analyzer. Images of the absorption, refraction and scattering effects are detected, such as on an image plate, and then digitized. The digitized images are simultaneously solved, preferably on a pixel-by-pixel basis, to derive a combined visual image which has dramatically improved contrast and spatial resolution over an image acquired through conventional radiology methods.

FRAGMENTATION AND SPREADING OF A METEOR-LIKE OBJECT  

SciTech Connect

The phenomenon of fragmentation and spreading of a high-speed flying object resembling a meteorite is studied experimentally and theoretically. Experimentally, a model made of graphite is launched in a ballistic range and is made to fragment and spread. The flow field produced by the cloud of the fragments is observed optically. The observed deceleration and spreading behavior is numerically reconstructed using computational-fluid-dynamic calculations, applying an improved meteoroid fragmentation theory. The existing meteoroid fragmentation theory is improved by introducing the hypothesis that the incubation process of the pressurized fluid permeating through the fragment precedes the splitting process. The incubation time is determined by the ratio of permeability of the fragment to the fluid's viscosity and is much longer than the time for splitting given by the existing theory. Agreement is obtained between the observed and calculated behavior of the fragment cloud by appropriately choosing this ratio.

Object-oriented approach to software development for LHC experiments  

E-Print Network (OSTI)

A proposal to study the viability of the Object Oriented (OO) approach for developing the code for LHC experiments. The authors will learn the key issues of this approach: OO analysis and design. Several methodologies will be studied to select the most appropiate for the High Energy Physics case. Some Computer Aided Software Engineering tools and implementation languages will be evaluated. These studies will be carried out with various well-defined prototypes, some of which have been defined in a preceding study and some of which will be defined in the course of this R&D project. It is also proposed to study how the OO approach enhances a different, and hopefully better, project management. Management tools will be tried and professional training will be organized.

Unidentified Moving Objects in Next Generation Time Domain Surveys  

E-Print Network (OSTI)

Existing and future wide-field photometric surveys will produce a time-lapse movie of the sky that will revolutionize our census of variable and moving astronomical and atmospheric phenomena. As with any revolution in scientific measurement capability, this new species of data will also present us with results that are sure to surprise and confound our understanding of the cosmos. While we cannot predict the unknown yields of such endeavors, it is a beneficial exercise to explore certain parameter spaces using reasonable assumptions for rates and observability. To this end I present a simple parameterized model of the detectability of unidentified flying objects (UFOs) with the Large Synoptic Survey Telescope (LSST). I also demonstrate that the LSST is well suited to place the first systematic constraints on the rate of UFO and extraterrestrial visits to our world.

Extremely faint high proper motion objects from SDSS stripe 82 - Optical classification spectroscopy of about 40 new objects  

E-Print Network (OSTI)

(abridged) Deep multi-epoch Sloan Digital Sky Survey data in a 275 square degrees area along the celestial equator (SDSS stripe 82 = S82) allowed us to search for extremely faint ($i>21$) objects with proper motions larger than 0.14 arcsec/yr. We classify 38 newly detected objects with low-resolution optical spectroscopy using FORS1 @ ESO VLT. All 22 previously known L dwarfs in S82 have been detected in our high proper motion survey. However, 11 of the known L dwarfs have smaller proper motions (0.01$$sdM7) subdwarfs. Some M subdwarf candidates have been classified based on spectral indices with large uncertainties. We failed to detect new nearby ($d<50$ pc) L dwarfs, probably because the S82 area was already well-investigated before. With our survey we have demonstrated a higher efficiency in finding Galactic halo CWDs than previous searches. The space density of halo CWDs is according to our results about 1.5-3.0 $\\times$ 10$^{-5}$ pc$^{-3}$.

The changing climate  

SciTech Connect

The earth owes its hospitable climate to the greenhouse effect, but now the effect threatens to intensify, rapidly warming the planet. Rising concentrations of carbon dioxide and other gases are the cause. The danger of warming is serious enough to warrant prompt action. The paper examines data on atmospheric warming and attempts to project effects into the future using atmospheric models. Three kinds of response to the threat are described: technical measures to counteract climatic change; adaptation to the changing climate; and prevention.

Objective 1: Extend Life, Improve Performance, and Maintain Safety of the Current Fleet Implementation Plan  

Science Conference Proceedings (OSTI)

Nuclear power has reliably and economically contributed almost 20% of electrical generation in the United States over the past two decades. It remains the single largest contributor (more than 70%) of non-greenhouse-gas-emitting electric power generation in the United States. By the year 2030, domestic demand for electrical energy is expected to grow to levels of 16 to 36% higher than 2007 levels. At the same time, most currently operating nuclear power plants will begin reaching the end of their 60 year operating licenses. Figure E 1 shows projected nuclear energy contribution to the domestic generating capacity. If current operating nuclear power plants do not operate beyond 60 years, the total fraction of generated electrical energy from nuclear power will begin to decline—even with the expected addition of new nuclear generating capacity. The oldest commercial plants in the United States reached their 40th anniversary in 2009. The U.S. Department of Energy Office of Nuclear Energy’s Research and Development (R&D) Roadmap has organized its activities in accordance with four objectives that ensure nuclear energy remains a compelling and viable energy option for the United States. The objectives are as follows: (1) develop technologies and other solutions that can improve the reliability, sustain the safety, and extend the life of the current reactors; (2) develop improvements in the affordability of new reactors to enable nuclear energy to help meet the Administration’s energy security and climate change goals; (3) develop sustainable nuclear fuel cycles; and (4) understand and minimize risks of nuclear proliferation and terrorism. The Light Water Reactor Sustainability (LWRS) Program is the primary programmatic activity that addresses Objective 1. This document describes how Objective 1 and the LWRS Program will be implemented. The existing U.S. nuclear fleet has a remarkable safety and performance record and today accounts for 70% of the low greenhouse gas emitting domestic electricity production. Extending the operating lifetimes of current plants beyond 60 years and, where possible, making further improvements in their productivity will generate early benefits from research, development, and demonstration investments in nuclear power. DOE’s role in Objective 1 is to partner with industry and the Nuclear Regulatory Commission in appropriate ways to support and conduct the long-term research needed to inform major component refurbishment and replacement strategies, performance enhancements, plant license extensions, and age-related regulatory oversight decisions. The DOE research, development, and demonstration role will focus on aging phenomena and issues that require long-term research and are generic to reactor type. Cost-shared demonstration activities will be conducted when appropriate.

Optimal slit orientation for long multi-object spectroscopic exposures  

E-Print Network (OSTI)

Historically, long-slit spectroscopic observations were carried out using the parallactic angle for the slit orientation if slit loss was an important consideration (either to maximize the signal-to-noise or to do spectrophotometry). This requires periodic realignment of the slit position angle as the parallactic angle changes. This is not possible for multi-slit observations where one slit position angle must be chosen for the entire exposure. Common wisdom suggests using the parallactic angle at the meridian (HA=0). In this paper, I examine what the best strategy is for long, multi-slit exposures. I find that in extreme cases (very long exposure time) the best choice is to orient the slit \\emph{perpendicular} to the parallactic angle at the meridian. There are two effects to consider: the increasing dispersion with increasing airmass and the changing angle between the parallactic angle and the slit. In the case of \\emph{traditional} slit orientation, the two effects amplify each other, thus rendering a significant fraction of the observation useless. Using the perpendicular orientation, the two processes work against each other, thus most of the observation remains useful. I will use, as an example, our 8 hour Lockman Hole observations using the Keck telescope, but generic methods are given to evaluate a particular observation. I also make the tools available to the community.

Laboratory tests of IEC DER object models for grid applications.  

Science Conference Proceedings (OSTI)

This report describes a Cooperative Research and Development Agreement (CRADA) between Salt River Project Agricultural Improvement and Power District (SRP) and Sandia National Laboratories to jointly develop advanced methods of controlling distributed energy resources (DERs) that may be located within SRP distribution systems. The controls must provide a standardized interface to allow plug-and-play capability and should allow utilities to take advantage of advanced capabilities of DERs to provide a value beyond offsetting load power. To do this, Sandia and SRP field-tested the IEC 61850-7-420 DER object model (OM) in a grid environment, with the goal of validating whether the model is robust enough to be used in common utility applications. The diesel generator OM tested was successfully used to accomplish basic genset control and monitoring. However, as presently constituted it does not enable plug-and-play functionality. Suggestions are made of aspects of the standard that need further development and testing. These problems are far from insurmountable and do not imply anything fundamentally unsound or unworkable in the standard.

Data quality objectives for Ion Exchange Module (IXM) disposition  

DOE Green Energy (OSTI)

This Data Quality Objective (DQO) document presents the data needs and accuracy requirements for sampling ion exchange modules at the K Basins, 100 K Area, to determine if there is a hydrogen gas buildup within the modules. This document was produced by PNL, with the assistance of Neptune and Associates, and was partly funded (for facilitator) by DOE-HQ as a demonstration DQO for EM activities. PNL involved a number of PNL, WHC and support contract staff (including external technical consultants) in meetings to define the data needed, along with the necessary accuracy, to resolve issues associated with hydrogen accumulation in Ion Exchange Modules (IXMS) that were generated prior to July 1994 and only have one nuc-fil vent. IXMs generated after July 1994 have multiple nuc-fil vents and do not require sampling. PNL transmitted this DQO to WHC on January 31, 1995. This Supporting Document is to assure that the document is captured into the document retrieval system. WHC review focused on the acceptability of the technical conclusions such that the data collected will meet minimum operational, safety and environmental needs.

Improving part based object detection by unsupervised, online boosting  

E-Print Network (OSTI)

Detection of objects of a given class is important for many applications. However it is difficult to learn a general detector with high detection rate as well as low false alarm rate. Especially, the labor needed for manually labeling a huge training sample set is usually not affordable. We propose an unsupervised, incremental learning approach based on online boosting to improve the performance on special applications of a set of general part detectors, which are learned from a small amount of labeled data and have moderate accuracy. Our oracle for unsupervised learning, which has high precision, is based on a combination of a set of shape based part detectors learned by off-line boosting. Our online boosting algorithm, which is designed for cascade structure detector, is able to adapt the simple features, the base classifiers, the cascade decision strategy, and the complexity of the cascade automatically to the special application. We integrate two noise restraining strategies in both the oracle and the online learner. The system is evaluated on two public video corpora. 1.

Data Quality Objectives Process for Designation of K Basins Debris  

SciTech Connect

The U.S. Department of Energy has developed a schedule and approach for the removal of spent fuels, sludge, and debris from the K East (KE) and K West (KW) Basins, located in the 100 Area at the Hanford Site. The project that is the subject of this data quality objective (DQO) process is focused on the removal of debris from the K Basins and onsite disposal of the debris at the Environmental Restoration Disposal Facility (ERDF). This material previously has been dispositioned at the Hanford Low-Level Burial Grounds (LLBGs) or Central Waste Complex (CWC). The goal of this DQO process and the resulting Sampling and Analysis Plan (SAP) is to provide the strategy for characterizing and designating the K-Basin debris to determine if it meets the Environmental Restoration Disposal Facility Waste Acceptance Criteria (WAC), Revision 3 (BHI 1998). A critical part of the DQO process is to agree on regulatory and WAC interpretation, to support preparation of the DQO workbook and SAP.

Performance objectives and criteria for conducting DOE environmental audits  

SciTech Connect

This document contains the Performance Objectives and Criteria (POC) that have been developed for environmental audits and assessments conducted by the Office of the Assistant Secretary for Environment, Safety and Health. The Environmental POC can serve multiple purposes. Primarily, they are to serve as guidelines for the technical specialists conducted the audits and assessments, and for the team management. The POC can also serve as supporting documents for training of technical discipline specialists and Team Leaders and as bases for DOE programs and field offices and contractors conducting audit or assessment activities or improving environmental protection programs. It must be recognized that not all of the POC will necessarily apply to all DOE facilities. The users of this document must rely upon their knowledge of the facility and their professional judgment, or the judgment of qualified environmental professionals to determine the applicability of each POC. The POC cover eleven technical disciplines: air; surface water and drinking water quality; groundwater; waste management; toxic and chemical materials; radiation; quality assurance; inactive waste sites and releases; ecological and cultural resources; the National Environmental Policy Act (NEPA); and environmental management systems.

Spent nuclear fuels project characterization data quality objectives strategy  

SciTech Connect

A strategy is presented for implementation of the Data Quality Objectives (DQO) process to the Spent Nuclear Fuels Project (SNFP) characterization activities. Westinghouse Hanford Company (WHC) and the Pacific Northwest Laboratory (PNL) are teaming in the characterization of the SNF on the Hanford Site and are committed to the DQO process outlined in this strategy. The SNFP characterization activities will collect and evaluate the required data to support project initiatives and decisions related to interim safe storage and the path forward for disposal. The DQO process is the basis for the activity specific SNF characterization requirements, termed the SNF Characterization DQO for that specific activity, which will be issued by the WHC or PNL organization responsible for the specific activity. The Characterization Plan prepared by PNL defines safety, remediation, and disposal issues. The ongoing Defense Nuclear Facility Safety Board (DNFSB) requirement and plans and the fuel storage and disposition options studies provide the need and direction for the activity specific DQO process. The hierarchy of characterization and DQO related documentation requirements is presented in this strategy. The management of the DQO process and the means of documenting the DQO process are described as well as the tailoring of the DQO process to the specific need of the SNFP characterization activities. This strategy will assure stakeholder and project management that the proper data was collected and evaluated to support programmatic decisions.

Integrated Geothermal Well Testing: Test Objectives and Facilities  

DOE Green Energy (OSTI)

A new and highly integrated geothermal well test program was designed for three geothermal operators in the US (MCR, RGI and Mapco Geothermal). This program required the design, construction and operation of new well test facilities. The main objectives of the test program and facilities are to investigate the critical potential and worst problems associated with the well and produced fluids in a period of approximately 30 days. Field and laboratory investigations are required to determine and quantify the problems of fluid production, utilization and reinjection. The facilities are designed to handle a flow rate from a geothermal well of one million pounds per hour at a wellhead temperature of approximately 268 C (515 F). The facilities will handle an entire spectrum of temperature and rate conditions up to these limits. All pertinent conditions for future fluid exploitations can be duplicated with these facilities, thus providing critical information at the very early stages of field development. The new well test facilities have been used to test high temperature, liquid-dominated geothermal wells in the Imperial Valley of California. The test facilities still have some problems which should be solvable. The accomplishments of this new and highly integrated geothermal well test program are described in this paper.

Data quality objectives for the initial K West fuel examinations  

SciTech Connect

The Data Quality Objectives (DQOs) were established for the examinations of the first group of fuel samples shipped from the K West Basin to the Hanford 327 Building hot cells for examinations to support the Path Forward recommended to solve the safety and environmental concerns associated with the deteriorating fuel in the K Basins. A separate DQO will be prepared for each future shipment of samples to the hot cells. The material stored in the K West Basin must ultimately be removed from the basin and placed in a stable storage configuration until it can be disposed of in a repository. The condition of the fuel in the closed canisters is a major uncertainty for any of the proposed actions. The major question to answer is what are the conditions of the materials in the closed canisters? The data to be gathered during the canister opening, handling, transport, associated hot cell handling, and examinations will also support decisions related to the Path Forward primarily in areas of transportation and the Multi-Canister Overpack (MCO) design.

MUTLI-OBJECTIVE OPTIMIZATION OF MICROSTRUCTURE IN WROUGHT MAGNESIUM ALLOYS  

SciTech Connect

The microstructural features that govern the mechanical properties of wrought magnesium alloys include grain size, crystallographic texture, and twinning. Several processes based on shear deformation have been developed that promote grain refinement, weakening of the basal texture, as well as the shift of the peak intensity away from the center of the basal pole figure - features that promote room temperature ductility in Mg alloys. At ORNL, we are currently exploring the concept of introducing nano-twins within sub-micron grains as a possible mechanism for simultaneously improving strength and ductility by exploiting a potential dislocation glide along the twin-matrix interface a mechanism that was originally proposed for face-centered cubic materials. Specifically, we have developed an integrated modeling and optimization framework in order to identify the combinations of grain size, texture and twin spacing that can maximize strength-ductility combinations. A micromechanical model that relates microstructure to material strength is coupled with a failure model that relates ductility to a critical shear strain and a critical hydrostatic stress. The micro-mechanical model is combined with an optimization tool based on genetic algorithm. A multi-objective optimization technique is used to explore the strength-ductility space in a systematic fashion and identify optimum combinations of the microstructural parameters that will simultaneously maximize the strength-ductility in the alloy.

Near-Earth Object Interception Using Nuclear Thermal Rock Propulsion  

DOE Green Energy (OSTI)

Planetary defense has drawn wide study: despite the low probability of a large-scale impact, its consequences would be disastrous. The study presented here evaluates available protection strategies to identify bottlenecks limiting the scale of near-Earth object that could be deflected, using cutting-edge and near-future technologies. It discusses the use of a nuclear thermal rocket (NTR) as a propulsion device for delivery of thermonuclear payloads to deflect or destroy a long-period comet on a collision course with Earth. A ‘worst plausible scenario’ for the available warning time (10 months) and comet approach trajectory are determined, and empirical data are used to make an estimate of the payload necessary to deflect such a comet. Optimizing the tradeoff between early interception and large deflection payload establishes the ideal trajectory for an interception mission to follow. The study also examines the potential for multiple rocket launch dates. Comparison of propulsion technologies for this mission shows that NTR outperforms other options substantially. The discussion concludes with an estimate of the comet size (5 km) that could be deflected usingNTRpropulsion, given current launch capabilities.

Reduce Climate Change  

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

Reduce Climate Change Reduce Climate Change Highway vehicles release about 1.5 billion metric tons of greenhouse gases (GHGs) into the atmosphere each year-mostly in the form of carbon dioxide (CO2)-contributing to global climate change. Each gallon of gasoline you burn creates 20 pounds of CO2. That's roughly 5 to 9 tons of CO2 each year for a typical vehicle. more... How can a gallon of gasoline create 20 pounds of carbon dioxide? It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but the oxygen in the air. When gasoline burns, the carbon and hydrogen separate. The hydrogen combines with oxygen to form water (H2O), and carbon combines with oxygen

Wind forecasting objectives for utility schedulers and energy traders  

DOE Green Energy (OSTI)

The wind energy industry and electricity producers can benefit in a number of ways from increased wind forecast accuracy. Higher confidence in the reliability of wind forecasts can help persuade an electric utility to increase the penetration of wind energy into its operating system and to augment the capacity value of wind electric generation. Reliable forecasts can also assist daily energy traders employed by utilities in marketing the available and anticipated wind energy to power pools and other energy users. As the number of utilities with wind energy experience grows, and wind energy penetration levels increase, the need for reliable wind forecasts will likely grow as well. This period of wind energy growth also coincides with advances in computer weather prediction technology that could lead to more accurate wind forecasts. Thus, it is important to identify the type of forecast information needed by utility schedulers and energy traders. This step will help develop approaches to the challenge of wind forecasting that will result in useful products being supplied to utilities or other energy generating entities. This paper presents the objectives, approach, and current findings of a US Department of Energy National Renewable Energy Laboratory (DOE/NREL) initiative to develop useful wind forecasting tools for utilities involved with wind energy generation. The focus of this initiative thus far has been to learn about the needs of prospective utility users. NREL representatives conducted a series of onsite interviews with key utility staff, usually schedulers and research planners, at seven US utilities. The purpose was to ascertain information on actual scheduling and trading procedures, and how utilities could integrate wind forecasting into these activities.

X-ray chemistry in envelopes around young stellar objects  

E-Print Network (OSTI)

We present chemical models of the envelope of a young stellar object (YSO) exposed to a central X-ray source. The models are applied to the massive star-forming region AFGL 2591 for different X-ray fluxes. The total X-ray ionization rate is dominated by the `secondary' ionization rate of H2 resulting from fast electrons. The carbon, sulphur and nitrogen chemistries are discussed. It is found that He+ and H3+ are enhanced and trigger a peculiar chemistry. Several molecular X-ray tracers are found and compared to tracers of the far ultraviolet (FUV) field. Like ultraviolet radiation fields, X-rays enhance simple hydrides, ions and radicals. In contrast to ultraviolet photons, X-rays can penetrate deep into the envelope and affect the chemistry even at large distances from the source. Whereas the FUV enhanced species cover a region of 200-300 AU, the region enhanced by X-rays is >1000 AU. Best-fit models for AFGL 2591 predict an X-ray luminosity LX > 1e+31 ergs/s with a hard X-ray spectrum TX > 3e+07 K. Furthermore, we find LX/Lbol ~ 1e-6. The chemistry of the bulk of the envelope mass is dominated by cosmic-ray induced reactions rather than by X-ray induced ionization for X-ray luminosities LX < 1e+33 ergs/s. The calculated line intensities of HCO+ and HCS+ show that high-J lines are more affected than lower J lines by the presence of X-rays due to their higher critical densities, and that such differences are detectable even with large aperture single-dish telescopes. Future instruments such as Herschel-HIFI or SOFIA will be able to observe X-ray enhanced hydrides whereas the sensitivity and spatial resolution of ALMA is well-suited to measure the size and geometry of the region affected by X-rays.

Water destruction by X-rays in young stellar objects  

E-Print Network (OSTI)

We study the H2O chemistry in star-forming environments under the influence of a central X-ray source and a central far ultraviolet (FUV) radiation field. The gas-phase water chemistry is modeled as a function of time, hydrogen density and X-ray flux. To cover a wide range of physical environments, densities between n_H = 10^4-10^9 cm^-3 and temperatures between T = 10-1000 K are studied. Three different regimes are found: For T water abundance is of order 10^-7-10^-6 and can be somewhat enhanced or reduced due to X-rays, depending on time and density. For 100 K 10^-3 ergs s-1 cm^-2 (t = 10^4 yrs) and for F_X > 10^-4 ergs s^-1 cm^-2 (t = 10^5 yrs). At higher temperatures (T > 250 K) and hydrogen densities, water can persist with x(H2O) ~ 10^-4 even for high X-ray fluxes. The X-ray and FUV models are applied to envelopes around low-mass Class 0 and I young stellar objects (YSOs). Water is destroyed in both Class 0 and I envelopes on relatively short timescales (t ~ 5000 yrs) for realistic X-ray fluxes, although the effect is less prominent in Class 0 envelopes due to the higher X-ray absorbing densities there. FUV photons from the central source are not effective in destroying water. The average water abundance in Class I sources for L_X > 10^27 ergs s^-1 is predicted to be x(H2O) < 10^-6.

Advanced information science and object-oriented technology for information management applications  

Science Conference Proceedings (OSTI)

The role of the military has been undergoing rapid change since the fall of the Berlin Wall. The kinds of missions the US military has been asked to participate in have often fallen into the category of {open_quotes}Military Operations Other Than War{close_quotes} and those involving military responses have been more of a surgical nature directed against different kinds of threats, like rogue states or in response to terrorist actions. As a result, the requirements on the military planner and analyst have also had to change dramatically. For example, preparing response options now requires rapid turnaround and a highly flexible simulation capability. This in turn requires that the planner or analyst have access to sophisticated information science and simulation technologies. In this paper, we shall discuss how advanced information science and object-oriented technologies can be used in advanced information management applications. We shall also discuss how these technologies and tools can be applied to DoD applications by presenting examples with a system developed at Argonne, the Dynamic Information Architecture System (DIAS). DIAS has been developed to exploit advanced information science and simulation technologies to provide tools for future planners and analysts.

Structural control Architecture Optimization for 3-D Systems Using Advanced Multi-Objective Genetic Algorithms  

E-Print Network (OSTI)

The architectures of the control devices in active control algorithm are an important fact in civil structural buildings. Traditional research has limitations in finding the optimal architecture of control devices such as using predefined numbers or locations of sensors and dampers within the 2-and 3-dimensional (3-D) model of the structure. Previous research using single-objective optimization only provides limited data for defining the architecture of sensors and control devices. The Linear Quadratic Gaussian (LQG) control algorithm is used as the active control strategy. The American Society of Civil Engineers (ASCE) control benchmark building definition is used to develop the building system model. The proposed gene manipulation genetic algorithm (GMGA) determines the near-optimal Pareto fronts which consist of varying numbers and locations of sensors and control devices for controlling the ASCE benchmark building by considering multi-objectives such as interstory drift and minimizing the number of the control devices. The proposed GMGA reduced the central processing unit (CPU) run time and produced more optimal Pareto fronts for the 2-D and 3-D 20-story building models. Using the GMGA provided several benefits: (1) the possibility to apply any presuggested multi-objective optimization mechanism; (2) the availability to perform a objective optimization problem; (3) the adoptability of the diverse encoding provided by the GA; (4) the possibility of including the engineering judgment in generating the next generation population by using a gene creation mechanisms; and (5) the flexibility of the gene creation mechanism in applying and changing the mechanism dependent on optimization problem. The near-optimal Pareto fronts obtained offer the structural engineer a diverse choice in designing control system and installing the control devices. The locations and numbers of the dampers and sensors in each story are highly dependent on the sensor locations. By providing near-Pareto fronts of possible solutions to the engineer that also consider diverse earthquakes, the engineer can get normalized patterns of architectures of control devices and sensors about random earthquakes.

Data Quality Objectives Supporting Radiological Air Emissions Monitoring for the PNNL Site  

Science Conference Proceedings (OSTI)

Pacific Northwest National Laboratory (PNNL) is in the process of developing a radiological air monitoring program for the PNNL Site that is distinct from that of the nearby Hanford Site. The original DQO (PNNL-19427) considered radiological emissions at the PNNL Site from Physical Sciences Facility (PSF) major emissions units. This first revision considers PNNL Site changes subsequent to the implementation of the original DQO. A team was established to determine how the PNNL Site changes would continue to meet federal regulations and address guidelines developed to monitor air emissions and estimate offsite impacts of radioactive material operations. The result is an updated program to monitor the impact to the public from the PNNL Site. The team used the emission unit operation parameters and local meteorological data as well as information from the PSF Potential-to-Emit documentation and Notices of Construction submitted to the Washington State Department of Health (WDOH). The locations where environmental monitoring stations would most successfully characterize the maximum offsite impacts of PNNL Site emissions from the three PSF buildings with major emission units were determined from these data. Three monitoring station locations were determined during the original revision of this document. This first revision considers expanded Department of Energy operations south of the PNNL Site and relocation of the two offsite, northern monitoring stations to sites near the PNNL Site fenceline. Inclusion of the southern facilities resulted in the proposal for a fourth monitoring station in the southern region. The southern expansion added two minor emission unit facilities and one diffuse emission unit facility. Relocation of the two northern stations was possible due to the use of solar power, rather than the previous limitation of the need for access to AC power, at these more remote locations. Addendum A contains all the changes brought about by the revision 1 considerations. This DQO report also updates the discussion of the Environmental Monitoring Plan for the PNNL Site air samples and how existing Hanford Site monitoring program results could be used. This document of Data Quality Objectives (DQOs) was prepared based on the U.S. Environmental Protection Agency (EPA) Guidance on Systematic Planning Using the Data Quality Objectives Process, EPA, QA/G4, 2/2006 (EPA 2006) as well as several other published DQOs.

Object-Oriented Intensional Programming: Intensional Classes Using Java and Lucid  

E-Print Network (OSTI)

This article introduces Object-Oriented Intensional Programming (OO-IP), a new hybrid language between Object-Oriented and Intensional Programming Languages in the sense of the latest evolutions of Lucid. This new hybrid language combines the essential characteristics of Lucid and Java, and introduces the notion of object streams which makes it is possible that each element in a Lucid stream to be an object with embedded intensional properties. Interestingly, this hybrid language also brings to Java objects the power to explicitly express and manipulate the notion of context, creating the novel concept of intensional object, i.e. objects whose evaluation is context-dependent, which are here demonstrated to be translatable into standard objects. By this new approach, we extend the use and meaning of the notion of intensional objects and enrich the meaning of object streams in Lucid and semantics of intensional objects in Java.

NEP for a Kuiper Belt Object Rendezvous Mission  

SciTech Connect

Kuiper Belt Objects (KBOs) are a recently-discovered set of solar system bodies which lie at about the orbit of Pluto (40 AU) out to about 100 astronomical units (AU). There are estimated to be about 100,000 KBOS with a diameter greater than 100 km. KBOS are postulated to be composed of the pristine material which formed our solar system and may even have organic materials in them. A detailed study of KBO size, orbit distribution, structure, and surface composition could shed light on the origins of the solar system and perhaps even on the origin of life in our solar system. A rendezvous mission including a lander would be needed to perform chemical analysis of the surface and sub-surface composition of KBOS. These requirements set the size of the science probe at around a ton. Mission analyses show that a fission-powered system with an electric thruster could rendezvous at 40 AU in about 13.0 years with a total {Delta}V of 46 krnk. It would deliver a 1000-kg science payload while providing ample onboard power for relaying data back to earth. The launch mass of the entire system (power, thrusters, propellant, navigation, communication, structure, science payload, etc.) would be 7984 kg if it were placed into an earth-escape trajectory (C=O). Alternatively, the system could be placed into a 700-km earth orbit with more propellant,yielding a total mass in LEO of 8618 kg, and then spiral out of earth orbit to arrive at the KBO in 14.3 years. To achieve this performance, a fission power system with 100 kW of electrical power and a total mass (reactor, shield, conversion, and radiator) of about 2350 kg. Three possible configurations are proposed: (1) a UZrH-fueled, NaK-cooled reactor with a steam Rankine conversion system, (2) a UN-fueled gas-cooled reactor with a recuperated Brayton conversion system, and (3) a UN-fueled heatpipe-cooled reactor with a recuperated Brayton conversion system. (Boiling and condensation in the Rankine system is a technical risk at present.) All three of these systems have the potential to meet the weight requirement for the trip and to be built in the near term.

Science Conference Proceedings (OSTI)

The Aspen Global Change Institute (AGCI) successfully organized and convened six interdisciplinary meetings over the course of award NNG04GA21G. The topics of the meetings were consistent with a range of issues, goals and objectives as described within the NASA Earth Science Enterprise Strategic Plan and more broadly by the US Global Change Research Program/Our Changing Planet, the more recent Climate Change Program Strategic Plan and the NSF Pathways report. The meetings were chaired by two or more leaders from within the disciplinary focus of each session. 222 scholars for a total of 1097 participants-days were convened under the auspices of this award. The overall goal of each AGCI session is to further the understanding of Earth system science and global environmental change through interdisciplinary dialog. The format and structure of the meetings allows for presentation by each participant, in-depth discussion by the whole group, and smaller working group and synthesis activities. The size of the group is important in terms of the group dynamics and interaction, and the ability for each participant's work to be adequately presented and discussed within the duration of the meeting, while still allowing time for synthesis

Frogs that change sex  

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

Frogs that change sex Frogs that change sex Name: Mike A Smola Age: N/A Location: N/A Country: N/A Date: N/A Question: Why can frogs (some species) change sex? Replies: This is a complex subject. Several studies have exposed some of the answers to this question, but a definitive answer is yet to be made. It all boils down to the level of which genes are activated. Studies have shown that the sex chromosomes are not necessarily the determining factor. The traditional display of a female is when an individual has two X chromosomes present. When one of these genes is a Y, it is a male. This tends to be the case for most organisms that sport individuals that are different sexes. However, the Y chromosomes has been almost always a male determining chromosome, but with molecular biology and genetic engineering techniques, a male can be made from a XX combination and females have developed from XY combinations. These are extremely rare, but they have given insight to the fact that there are other factors beside X and Y chromosomes that determine sex, probably a gene found in both chromosomes.

Expanding Buildings-to-Grid (B2G) Objectives in India  

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

Expanding Buildings-to-Grid (B2G) Objectives in India Expanding Buildings-to-Grid (B2G) Objectives in India Title Expanding Buildings-to-Grid (B2G) Objectives in India Publication Type Report LBNL Report Number LBNL-6369E Year of Publication 2013 Authors Ghatikar, Girish, Venkata Ganti, and Chandrayee Basu Date Published 07/2013 Keywords market sectors, technologies Abstract India faces significant challenges in providing a reliable electricity supply. This was manifest in a power grid failure that resulted in the country's worst blackout, which affected states where 50% of India's 1.2 billion people live. The Government of India is taking measures to address the situation of aging grid infrastructure and integrated demand-side management. The National Action Plan on Climate Change of 2008 outlines a National Mission on Enhanced Energy Efficiency with actions for electricity sector reform. The U.S.-India Energy Dialogue provides a mechanism for joint activities to address energy issues and electric grid integration. The scope of the buildings-to-grid (B2G) activities by Lawrence Berkeley National Laboratory (LBNL) have been delineated primarily based on the expertise of LBNL understanding responsive loads for Smart Grid deployments in the United States. This study leverages parallel Smart Grid activities by the Indian and U.S. stakeholders. Its goal is to establish a sustainable B2G collaboration between the U.S. and India, which will facilitate integration of demand-side systems with supply-side systems to advance India's electricity reliability goals. The study will motivate Indian electricity markets by disseminating U.S. experiences and technologies for the uptake of demand response (DR) pilot studies in India. The study delineates immediate and long-term intervention through systematic review of issues, U.S. experiences, and technologies that support local missions. It provides background and description of energy efficiency and DR framework through an organized review of the literature pertaining to various aspects of India's B2G activities. The results are short-term and long-term DR and energy-efficiency integrated action plans for pilot studies and transformative technologies for mitigation and adaptation of electricity reliability. The findings will aid Smart Grid market transformation and policy interventions through technology demonstrations. Based on the priorities identified, a plan for B2G technology pilot studies in India is proposed.

Objective methods to evaluate rheological properties of wheat flour tortilla dough  

E-Print Network (OSTI)

Characteristics of wheat flour tortilla dough were measured on a texture analyzer using texture profile analysis (TPA), stress relaxation, extensibility and adhesiveness tests. Doughs were optimally mixed, rested, divided, rounded and sampled during resting. Concentrations of water, fat, reducing agent and acidulants were varied to prepare a viscoelastic solid, viscoelastic liquid, and control doughs for subjective and objective evaluations of dough properties. TPA hardness and resilience exhibited low variability (CV= 1-9%) and correlated significantly with subjective dough properties (smoothness, r--0.88; softness, r--0.90; toughness, r--0.91). TPA adhesiveness and springiness were not sensitive to differences in doughs during resting or by dough formulations and among doughs.Resistance to extension and dough extensibility showed low variability (CV= 3-12%). Dough extensibility method was sensitive enough to indicate significant differences during resting and among doughs. Both parameters gave significant correlations with subjective dough evaluations (resistance to extension, softness, r-0.95; toughness, r--0.95; extensibility, softness, r---0.85; toughness, r---0.86). Adhesive force measured by Chen-Hoseney dough stickiness method showed moderate variability (CV= 5-17%), but failed to differentiate the doughs. This method was insensitive to changes during resting since a freshly mixed dough surface was created for testing. Adhesive force correlated significantly with subjective dough properties (smoothness, r = 0.89; softness, r--0.89; toughness, r = 0.89). Equilibrium modulus (stress relaxation) showed low variability (CV= 7-10%) and correlated significantly with subjective dough evaluations (softness, r--0.95; toughness, r--0.96). TPA and dough extensibility, were utilized to evaluate doughs made from different formulations and processing conditions. Tortillas were made to determine the relationships between objective dough evaluations and tortilla characteristics. Hardness, resilience, and resistance to extension increased and extensibility decreased for doughs containing less fat, less cysteine, and/or more gluten. Dough extensibility parameters correlated significantly with subjective dough evaluations (softness, r-0.60; toughness, r--0.61). TPA hardness and resilience correlated significantly with tortilla characteristics (diameter, r=-0.58; height, r--0.65; weight, r--0.66). TPA (hardness and resilience) and dough extensibility methods were effective in characterizing dough properties. However, practical application of these objective Theological methods must be confirmed in commercial tortilla plants.

Enzymatic temperature change indicator  

DOE Patents (OSTI)

A temperature change indicator is described which is composed of an enzyme and a substrate for that enzyme suspended in a solid organic solvent or mixture of solvents as a support medium. The organic solvent or solvents are chosen so as to melt at a specific temperature or in a specific temperature range. When the temperature of the indicator is elevated above the chosen, or critical temperature, the solid organic solvent support will melt, and the enzymatic reaction will occur, producing a visually detectable product which is stable to further temperature variation.

New concept for quantification of similarity relates entropy and energy of objects: First and Second Law entangled, equivalence of temperature and time proposed  

E-Print Network (OSTI)

When the difference between changes in energy and entropy at a given temperature is correlated with the ratio between the same changes in energy and entropy at zero average free energy of an ensemble of similar but distinct molecule-sized objects, a highly significant linear dependence results from which a relationship between energy and entropy is derived and the degree of similarity between the distinctly different members within the group of objects can be quantified. This fundamental energy-entropy relationship is likely to be of general interest in physics, most notably in particle physics and cosmology. We predict a consistent and testable way of classifying mini black holes, to be generated in future Large Hadron Collider experiments, by their gravitational energy and area entropy. For any isolated universe we propose absolute temperature and absolute time to be equivalent, much in the same way as energy and entropy are for an isolated ensemble of similar objects. According to this principle, the cosmo...

Data Quality Objectives for Regulatory Requirements for Hazardous and Radioactive Air Emissions Sampling and Analysis  

SciTech Connect

This document describes the results of the data quality objective (DQO) process undertaken to define data needs for state and federal requirements associated with toxic, hazardous, and/or radiological air emissions under the jurisdiction of the River Protection Project (RPP). Hereafter, this document is referred to as the Air DQO. The primary drivers for characterization under this DQO are the regulatory requirements pursuant to Washington State regulations, that may require sampling and analysis. The federal regulations concerning air emissions are incorporated into the Washington State regulations. Data needs exist for nonradioactive and radioactive waste constituents and characteristics as identified through the DQO process described in this document. The purpose is to identify current data needs for complying with regulatory drivers for the measurement of air emissions from RPP facilities in support of air permitting. These drivers include best management practices; similar analyses may have more than one regulatory driver. This document should not be used for determining overall compliance with regulations because the regulations are in constant change, and this document may not reflect the latest regulatory requirements. Regulatory requirements are also expected to change as various permits are issued. Data needs require samples for both radionuclides and nonradionuclide analytes of air emissions from tanks and stored waste containers. The collection of data is to support environmental permitting and compliance, not for health and safety issues. This document does not address health or safety regulations or requirements (those of the Occupational Safety and Health Administration or the National Institute of Occupational Safety and Health) or continuous emission monitoring systems. This DQO is applicable to all equipment, facilities, and operations under the jurisdiction of RPP that emit or have the potential to emit regulated air pollutants.

Sensitive Measures of Condition Change in EEG Data  

SciTech Connect

We present a new, robust, model-independent technique for measuring condition change in nonlinear data. We define indicators of condition change by comparing distribution functions (DF) defined on the attractor for time windowed data sets via L{sub 1}-distance and {chi}{sup 2} statistics. The new measures are applied to EEG data with the objective of detecting the transition between non-seizure and epileptic brain activity in an accurate and timely manner. We find a clear superiority of the new metrics in comparison to traditional nonlinear measures as discriminators of condition change.

Present and future nuclear power generation as a reflection of individual countries' resources and objectives  

SciTech Connect

The nuclear reactor industry has been in a state of decline for more than a decade in most of the world. The reasons are numerous and often unique to the energy situation of individual countries. Two commonly cited issues influence decisions relating to construction of reactors: costs and the need, or lack thereof, for additional generating capacity. Public concern has ''politicized'' the nuclear industry in many non-communist countries, causing a profound effect on the economics of the option. The nuclear installations and future plans are reviewed on a country-by-country basis for 36 countries in the light of the resources and objectives of each. Because oil and gas for power production throughout the world are being phased out as much as possible, coal-fired generation currently tends to be the chosen alternative to nuclear power production. Exceptions occur in many of the less developed countries that collectively have a very limited operating experience with nuclear reactors. The Chernobyl accident in the USSR alarmed the public; however, national strategies and plans to build reactors have not changed markedly in the interim. Assuming that the next decade of nuclear power generation is uneventful, additional electrical demand would cause the nuclear power industry to experience a rejuvenation in Europe as well as in the US. 80 refs., 3 figs., 22 tabs.
