Premature Raman backscattering of a laser pump by plasma noise might be suppressed by an appropriate detuning of the Raman resonance, even as the desired amplification of the seed persists with a high efficiency. In this paper, we analyze side-scattering of laser pumps by plasma noise in backward Raman amplifiers. Though its growth rate is smaller than that of backscattering, the side-scattering can nevertheless be dangerous, because of a longer path of side-scattered pulses in plasmas and because of an angular dependence of the Raman resonance detuning. We show that side-scattering of laser pumps by plasma noise in BRA might be suppressed to a tolerable level at all angles by an appropriate combination of two detuning mechanisms associated with plasma density gradient and pump chirp.</p>Using GIS to Identify Remediation Areas in Landfills2016-09-22T02:13:12-05:00https://digital.library.unt.edu/ark:/67531/metadc877245/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc877245/"><img alt="Using GIS to Identify Remediation Areas in Landfills" title="Using GIS to Identify Remediation Areas in Landfills" src="https://digital.library.unt.edu/ark:/67531/metadc877245/thumbnail/"/></a></p><p>This paper reports the use of GIS mapping software—ArcMap and ArcInfo Workstation—by the Idaho National Engineering and Environmental Laboratory (INEEL) as a non-intrusive method of locating and characterizing radioactive waste in a 97-acre landfill to aid in planning cleanup efforts. The fine-scale techniques and methods used offer potential application for other burial sites for which hazards indicate a non-intrusive approach. By converting many boxes of paper shipping records in multiple formats into a relational database linked to spatial data, the INEEL has related the paper history to our current GIS technologies and spatial data layers. The wide breadth of GIS techniques and tools quickly display areas in need of remediation as well as evaluate methods of remediation for specific areas as the site characterization is better understood and early assumptions are refined.</p>Simulation of a Production Facility with an Automated Transport System2015-12-03T09:30:17-06:00https://digital.library.unt.edu/ark:/67531/metadc788537/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc788537/"><img alt="Simulation of a Production Facility with an Automated Transport System" title="Simulation of a Production Facility with an Automated Transport System" src="https://digital.library.unt.edu/ark:/67531/metadc788537/thumbnail/"/></a></p><p>A model was needed to assess material throughput and validate the conceptual design of a production facility, including equipment lists and layout. The initial desire was to use a commercially available discrete event simulation package. However, the available software was found to be too limited in capability. Database interface software was used to develop autonomous intelligent manufacturing workstations and material transporters. The initial Extend model used to assess material throughput and develop equipment lists for the preconceptual design effort was upgraded with software add-ons from Simulation Dynamics, Inc. (SDI). Use of the SDI database interface allowed the upgraded model to include: 1. a material mass balance at any level of detail required by the user, and 2. a transport system model that includes all transport system movements, time delays, and transfers between systems. This model will assist in evaluating transport system capacity, sensitive time delays in the system, and optimal operating strategies. An additional benefit of using the SDI database interface is dramatically improved run time performance. This allows significantly more runs to be completed to provide better statistics for overall plant performance. The model has all system and process parameters entered into sub-component accessible tables. All information for the manufactured items and process data is automatically generated and written to the database. The standard software is used for the movement of manufactured items between workstations, and for sequence and timing functions. Use of the database permits almost unlimited process control and data collection with an insignificant effect on run time.</p>[Project Summary: Deepwater Program: The Technology and Economics of Deepwater Production Projects]2017-02-20T06:21:05-06:00https://digital.library.unt.edu/ark:/67531/metadc955484/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc955484/"><img alt="[Project Summary: Deepwater Program: The Technology and Economics of Deepwater Production Projects]" title="[Project Summary: Deepwater Program: The Technology and Economics of Deepwater Production Projects]" src="https://digital.library.unt.edu/ark:/67531/metadc955484/thumbnail/"/></a></p><p>Report summary describing the work completed at ABS Group, Inc. for 'Deepwater Program: The Technology and Economics of Deepwater Production Projects'.

The process uses a closed system approach to retain fission products/gases inside a sealed canister after treatment. The MMD process melts and dilutes spent fuel with depleted uranium to obtain an isotopic content of less than 20 percent. The final ingot is solidified inside the sealed canister and can be stored safely either wet or dry until final disposition or reprocessing. The MMD module can be staged at or near the research reactor fuel storage sites to facilitate the melt-dilute treatment of the spent fuel into a stable non-proliferable form.</p>Sorption of Cesium From Aqueous Waste Solution on SuperLig 644 Resin2015-12-03T09:30:17-06:00https://digital.library.unt.edu/ark:/67531/metadc782812/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc782812/"><img alt="Sorption of Cesium From Aqueous Waste Solution on SuperLig 644 Resin" title="Sorption of Cesium From Aqueous Waste Solution on SuperLig 644 Resin" src="https://digital.library.unt.edu/ark:/67531/metadc782812/thumbnail/"/></a></p><p>The removal of cesium from aqueous waste solution was investigated in a column setup using SuperLig(R) 644 resin. The resin was significantly coarser in size than those used in previous studies because of hydraulic problems encountered during pilot-scale tests. The bed volume (BV = 140) at the onset of breakthrough surpassed the design requirement of 100 BV at 50 percent breakthrough. The percent of cesium removed by the resin at the onset of breakthrough was 99.96. The elution of cesium with 0.5 M HNO3 was satisfactory with a peak BV of 2.5. The elution BV for C/Co = 0.01 was 10, which is less than the target of 15 BV. The percent of sorbed cesium eluted from the resin was 99.88 percent. In addition, the BV of the various solutions used for the supporting process steps (feed displacement, post-feed displacement rinse, post-elution rinse, and regeneration) of the cesium ion exchange system was sufficient.</p>PROPOSAL FOR A SILICON VERTEX TRACKER (VTX) FOR THE PHENIX EXPERIMENT.2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1407910/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1407910/"><img alt="PROPOSAL FOR A SILICON VERTEX TRACKER (VTX) FOR THE PHENIX EXPERIMENT." title="PROPOSAL FOR A SILICON VERTEX TRACKER (VTX) FOR THE PHENIX EXPERIMENT." src="https://digital.library.unt.edu/ark:/67531/metadc1407910/thumbnail/"/></a></p><p>We propose the construction of a Silicon Vertex Tracker (VTX) for the PHENIX experiment at RHIC. The VTX will substantially enhance the physics capabilities of the PHENIX central arm spectrometers. Our prime motivation is to provide precision measurements of heavy-quark production (charm and beauty) in A+A, p(d)+A, and polarized p+p collisions. These are key measurements for the future RHIC program, both for the heavy ion program as it moves from the discovery phase towards detailed investigation of the properties of the dense nuclear medium created in heavy ion collisions, and for the exploration of the nucleon spin-structure functions. In addition, the VTX will also considerably improve other measurements with PHENIX. The main physics topics addressed by the VTX are: (1) Hot and dense strongly interacting matter--Potential enhancement of charm production; Open beauty production; Flavor dependence of jet quenching and QCD energy loss; Accurate charm reference for quarkonium; Thermal dilepton radiation; High p{sub T} phenomena with light flavors above 10-15 GeV/c in p{sub T}; and Upsilon spectroscopy in the e{sup +}e{sup -} decay channel. (2) Gluon spin structure of the nucleon--{Delta}G/G with charm; {Delta}G/G with beauty; and x dependence of {Delta}G/G with {gamma}-jet correlations. (3) Nucleon structure in nuclei--Gluon shadowing over broad x-range. With the present PHENIX detector, heavy-quark production has been measured indirectly through the observation of single electrons. These measurements are inherently limited in accuracy by systematic uncertainties resulting from the large electron background from Dalitz decays and photon conversions. In particular, the statistical nature of the analysis does not allow for a model-independent separation of the charm and beauty contributions. The VTX detector will provide vertex tracking with a resolution of <50 {micro}m over a large coverage both in rapidity (|{eta}| < 1.2) and in azimuthal angle ({Delta}{phi} {approx} 2{pi}). With this device, significantly enhanced and qualitatively new data can be obtained. A more robust and accurate measurement of heavy-quark production over a wide kinematics range will be possible. The main benefits are in three areas. Firstly, by selecting electrons with a distance of closest approach (DCA) to the primary vertex larger than {approx}100 {micro}m, the background will be suppressed by several orders of magnitude and thereby a clean and robust measurement of heavy flavor production in the single electron channel will become available. Secondly, because the lifetime of mesons with beauty is significantly larger than that of mesons with charm, the VTX information will allow us to disentangle charm from beauty production over a broad p{sub T} range. Thirdly, a DCA cut on hadrons will reduce the combinatorial background of K{pi} to an extent that a direct measurement of D mesons through this decay channel will become possible. In addition, the VTX detector will substantially extend our p{sub T} coverage in high p{sub T} charged particles, and it also will enable us to measure {gamma}+jet correlations.</p>PROPOSAL FOR A SILICON VERTEX TRACKER (VTX) FOR THE PHENIX EXPERIMENT2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1404649/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1404649/"><img alt="PROPOSAL FOR A SILICON VERTEX TRACKER (VTX) FOR THE PHENIX EXPERIMENT" title="PROPOSAL FOR A SILICON VERTEX TRACKER (VTX) FOR THE PHENIX EXPERIMENT" src="https://digital.library.unt.edu/ark:/67531/metadc1404649/thumbnail/"/></a></p><p>We propose the construction of a Silicon Vertex Tracker (VTX) for the PHENIX experiment at RHIC.

The new materials produced have been investigated by X-ray diffraction (XRD), transition electron microscope (TEM), scanning electron microscope (SEM) and electron energy dispersion spectrum (EDS) for their phase compositions, crystal structure, grain size, particle morphology and the distribution of catalyst element. Hydrogen storage capacities and the hydriding-dehydriding kinetics of the new materials have been measured at different temperatures using a Sieverts apparatus. It is observed that mechanical alloying accelerates the hydrogenation kinetics of the magnesium based materials at low temperature, but a high temperature must be provided to release the absorbed hydrogen from the hydrided magnesium based materials. It is believed that the dehydriding temperature is largely controlled by the thermodynamic configuration of magnesium hydride. Doping Mg-Ni nano/amorphous composite materials with lanthanum reduces the hydriding and dehydriding temperature. Although the stability of MgH2 can not be easily reduced by ball milling alone, the results suggest the thermodynamic properties of Mg-Ni nano/amorphous composite materials can be alternated by additives such as La or other effective elements. Further investigation toward understanding the mechanism of additives will be rewarded.</p>Hydrogen Storage Properties of the Tetrahydrofuran Treated Magnesium2015-12-03T09:30:17-06:00https://digital.library.unt.edu/ark:/67531/metadc780621/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc780621/"><img alt="Hydrogen Storage Properties of the Tetrahydrofuran Treated Magnesium" title="Hydrogen Storage Properties of the Tetrahydrofuran Treated Magnesium" src="https://digital.library.unt.edu/ark:/67531/metadc780621/thumbnail/"/></a></p><p>The electronic structure, crystalline feature and morphology of the tetrahydrofuran (THF) treated magnesium, along with its hydriding and dehydriding properties have been investigated. The THF treated magnesium absorbs 6.3 wt per cent hydrogen at 723K and 3.5 MPa. After hydrogenation, in addition to the expected MgH2, a new less-stable hydride phase appears at 673K, but not at a lower temperature. Desorption produces 5.5 wt per cent hydrogen at 723K against a back pressure of 1.3 Pa after 20 cycles of hydriding-dehydriding. The THF treatment improves the kinetics of hydrogen absorption and desorption significantly. From 723K to 623K, the THF treated Mg demonstrates acceptable reaction rates. XPS studies show that tetrahydrofuran treatment causes the electronic energy state of the magnesium surface atoms to change, but the XRD studies show the crystal structure remains unchanged. Metallographic observation of the bulk hydrides of THF treated magnesium reveal they are poly-crystalline wi th the wide-spreading slip bands and twins within the crystals, indicating the phase transformation upon hydriding causes serious stress and distortion. It appears this microstructural deformation explains the much higher energy requirements (higher pressure and temperature) for magnesium hydrogenation than the simple lattice expansion that accompany hydrogen uptake for LaNi5 and FeTi.</p>ELECTRICAL SUBSTATION RELIABILITY EVALUATION WITH EMPHASIS ON EVOLVING INTERDEPENDENCE ON COMMUNICATION INFRASTRUCTURE.2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1407390/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1407390/"><img alt="ELECTRICAL SUBSTATION RELIABILITY EVALUATION WITH EMPHASIS ON EVOLVING INTERDEPENDENCE ON COMMUNICATION INFRASTRUCTURE." title="ELECTRICAL SUBSTATION RELIABILITY EVALUATION WITH EMPHASIS ON EVOLVING INTERDEPENDENCE ON COMMUNICATION INFRASTRUCTURE." src="https://digital.library.unt.edu/ark:/67531/metadc1407390/thumbnail/"/></a></p><p>The objective of this study is to develop a methodology for a probabilistic assessment of the reliability and security of electrical energy distribution networks. This includes consideration of the future grid system, which will rely heavily on the existing digitally based communication infrastructure for monitoring and protection. Another important objective of this study is to provide information and insights from this research to Consolidated Edison Company (Con Edison) that could be useful in the design of the new network segment to be installed in the area of the World Trade Center in lower Manhattan. Our method is microscopic in nature and relies heavily on the specific design of the portion of the grid being analyzed. It extensively models the types of faults that a grid could potentially experience, the response of the grid, and the specific design of the protection schemes. We demonstrate that the existing technology can be extended and applied to the electrical grid and to the supporting communication network. A small subsection of a hypothetical grid based on the existing New York City electrical grid system of Con Edison is used to demonstrate the methods. Sensitivity studies show that in the current design the frequency for the loss of the main station is sensitive to the communication network reliability. The reliability of the communication network could become a more important contributor to the electrical grid reliability as the utilization of the communication network significantly increases in the near future to support ''smart'' transmission and/or distributed generation. The identification of potential failure modes and their likelihood can support decisions on potential modifications to the network including hardware, monitoring instrumentation, and protection systems.</p>Power Technologies Data Book 2003 Edition2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1407770/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1407770/"><img alt="Power Technologies Data Book 2003 Edition" title="Power Technologies Data Book 2003 Edition" src="https://digital.library.unt.edu/ark:/67531/metadc1407770/thumbnail/"/></a></p><p>The 2003 edition of this report, prepared by NREL's Energy Analysis Office, includes up-to-date information on power technologies, including complete technology profiles.

We extend the framework of the halo model of cosmological nonlinear matter clustering to include the effect of massive neutrino infall into cold dark matter (CDM) halos. The magnitude of the effect of neutrino clustering for three degenerate mass neutrinos with m{sub v{sub 1}} = 0.9 eV is of order {approx}1%, within the potential sensitivity of upcoming weak lensing surveys. In order to use these measurements to further constrain--or eventually detect--neutrino masses, accurate theoretical predictions of the nonlinear power spectrum in the presence of massive neutrinos will be needed, likely only possible through high-resolution multiple particle (neutrino, CDM and baryon) simulations.</p>First measurement of sigma (p anti-p ---> Z) .

Final Technical Report" src="https://digital.library.unt.edu/ark:/67531/metadc782275/thumbnail/"/></a></p><p>A novel high-heat transfer low NO(sub x) natural gas combustion system. The objectives of this program are to research, develop, test, and commercialize a novel high-heat transfer low-NO{sub x} natural gas combustion system for oxygen-, oxygen-enriched air, and air-fired furnaces. This technology will improve the process efficiency (productivity and product quality) and the energy efficiency of high-temperature industrial furnaces by at least 20%. GTI's high-heat transfer burner has applications in high-temperature air, oxygen-enriched air, and oxygen furnaces used in the glass, metals, cement, and other industries. Development work in this program is focused on using this burner to improve the energy efficiency and productivity of glass melting furnaces that are major industrial energy consumers. The following specific project objectives are defined to provide a means of achieving the overall project objectives. (1) Identify topics to be covered, problems requiring attention, equipment to be used in the program, and test plans to be followed in Phase II and Phase III. (2) Use existing codes to develop models of gas combustion and soot nucleation and growth as well as a thermodynamic and parametric description of furnace heat transfer issues. (3) Conduct a parametric study to confirm the increase in process and energy efficiency. (4) Design and fabricate a high-heat transfer low-NOx natural gas burners for laboratory, pilot- and demonstration-scale tests. (5) Test the high-heat transfer burner in one of GTI's laboratory-scale high-temperature furnaces. (6) Design and demonstrate the high-heat transfer burner on GTI's unique pilot-scale glass tank simulator. (7) Complete one long term demonstration test of this burner technology on an Owens Corning full-scale industrial glass melting furnace. (8) Prepare an Industrial Adoption Plan. This Plan will be updated in each program Phase as additional information becomes available. The Plan will include technical and economic analyses, energy savings and waste reduction predictions, evaluation of environmental effects, and outline issues concerning manufacturing, marketing, and financing. Combustion Tec, Owens Corning, and GTI will all take active roles in defining this Plan. During Phase I, the first three objectives were addressed and completed along with the design component of the fourth objective. In Phase II, the fabrication component of the fourth objective was completed along with objectives five and six. Results of the Phase I work were reported in the Phase I Final Report and are summarized in this Final Technical Report. Work for Phase II was divided in four specific Tasks. Results of the Phase II work were reported in the Phase II Final Report and are also summarized in this Final Technical Report. No Phase III Final Report was prepared, so this Final Technical Report presents the results of Phase III commercial demonstration efforts. A description of each Task in Phases I, II, and III is presented in this report.</p>Colloid-Facilitated Plutonium Transport in Saturated Alluvium2015-12-03T09:30:17-06:00https://digital.library.unt.edu/ark:/67531/metadc786904/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc786904/"><img alt="Colloid-Facilitated Plutonium Transport in Saturated Alluvium" title="Colloid-Facilitated Plutonium Transport in Saturated Alluvium" src="https://digital.library.unt.edu/ark:/67531/metadc786904/thumbnail/"/></a></p><p>Natural groundwater colloids have been recognized as possible agents for enhancing the subsurface transport of strongly-sorbing radionuclides. To evaluate this mechanism, packed-bed column experiments were conducted comparing the simultaneous transport of dissolved plutonium (Pu), Pu sorbed onto natural colloids, 190-nm and 500-nm diameter fluorescent CML microspheres, and tritiated water in saturated alluvium. Experiments were conducted in two columns having slightly different porosities at two flow rates, resulting in average linear velocities (v{sub z}) of 0.6 to 3.65 cm/hr in one column and 0.57 to 2.85 cm/hr in the other. In all experiments, Pu associated with natural colloids transported through alluvium essentially unretarded, while dissolved Pu was entirely retained. These results were consistent with the strong sorption of Pu to alluvium and the negligible desorption from natural colloids, observed in separate batch experiments, over time scales exceeding those of the column experiments. Breakthroughs of natural colloids preceded tritiated water in all experiments, indicating a slightly smaller effective pore volume for the colloids. The enhancement of colloids transport over tritiated water decreased with v{sub z}, implying {approx} 40% enhancement at v{sub z} = 0. The 500-nm CML microspheres were significantly attenuated in the column experiments compared to the 190-nm microspheres, which exhibited slightly more attenuation than natural colloids.</p>LSST data pipeline prototyping plans and strategy2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1413454/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1413454/"><img alt="LSST data pipeline prototyping plans and strategy" title="LSST data pipeline prototyping plans and strategy" src="https://digital.library.unt.edu/ark:/67531/metadc1413454/thumbnail/"/></a></p><p>In this document we describe our approach and strategy for building the prototype for the image-stream analysis data pipeline.

The simulated pipeline will be used to research and evaluate software architectures that are efficient and flexible. It will also be used to define the real-time software and hardware requirements needed to support the anticipated LSST data rates. The LSST data pipeline requirements are still being defined, however, previous surveys can provide a good source for data requirements. Our approach is to use the SuperMacho data pipeline as a prototyping tool to identify a framework for building Modular Data-Centric Pipeline (MDCP) architectures. The prototyping is done in a hierarchical fashion to help capture and define the general data attributes (schema) first. We then model other necessary components based on science and performance requirements. We use identified schemas or data attributes as a way to define a data model for LSST.</p>Electric Reliability: Options for Electric Transmission Infrastructure Improvements2008-12-11T20:14:07-06:00https://digital.library.unt.edu/ark:/67531/metacrs10200/<p><a href="https://digital.library.unt.edu/ark:/67531/metacrs10200/"><img alt="Electric Reliability: Options for Electric Transmission Infrastructure Improvements" title="Electric Reliability: Options for Electric Transmission Infrastructure Improvements" src="https://digital.library.unt.edu/ark:/67531/metacrs10200/thumbnail/"/></a></p><p>The electric utility industry is inherently capital intensive.
