He developed a distributed steady-state genetic algorithm in conjunction with a specialized local search heuristic for solving the set partitioning problem. The genetic algorithm is based on an island model where multiple independent subpopulations each run a steady-state genetic algorithm on their subpopulation and occasionally fit strings migrate between the subpopulations. Tests on forty real-world set partitioning problems were carried out on up to 128 nodes of an IBM SP1 parallel computer. The authors found that performance, as measured by the quality of the solution found and the iteration on which it was found, improved as additional subpopulation found and the iteration on which it was found, improved as additional subpopulations were added to the computation. With larger numbers of subpopulations the genetic algorithm was regularly able to find the optimal solution to problems having up to a few thousand integer variables. In two cases, high-quality integer feasible solutions were found for problems with 36,699 and 43,749 integer variables, respectively. A notable limitation they found was the difficulty solving problems with many constraints.</p>A Recharacterization of the Age-Length and Growth Relationships of Hawaiian Snapper, Pristipomoides filamentosus2018-01-15T19:06:51-06:00https://digital.library.unt.edu/ark:/67531/metadc1050045/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1050045/"><img alt="A Recharacterization of the Age-Length and Growth Relationships of Hawaiian Snapper, Pristipomoides filamentosus" title="A Recharacterization of the Age-Length and Growth Relationships of Hawaiian Snapper, Pristipomoides filamentosus" src="https://digital.library.unt.edu/ark:/67531/metadc1050045/thumbnail/"/></a></p><p>This report analyzes data collected on a study of age-length and somatic growth interrelationships for the Hawaiian pink snapper, or "opakapaka," Pristipomoides filamentosus.</p>Studies of Acute and Chronic Radiation Injury at the Biological and Medical Research Division, Argonne National Laboratory, 1953-1970 : Description of Individual Studies, Data Files, Codes, and Summaries of Significant Findings2015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc283164/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc283164/"><img alt="Studies of Acute and Chronic Radiation Injury at the Biological and Medical Research Division, Argonne National Laboratory, 1953-1970 : Description of Individual Studies, Data Files, Codes, and Summaries of Significant Findings" title="Studies of Acute and Chronic Radiation Injury at the Biological and Medical Research Division, Argonne National Laboratory, 1953-1970 : Description of Individual Studies, Data Files, Codes, and Summaries of Significant Findings" src="https://digital.library.unt.edu/ark:/67531/metadc283164/thumbnail/"/></a></p><p>Between 1953 and 1970, studies on the long-term effects of external x-ray and {gamma} irradiation on inbred and hybrid mouse stocks were carried out at the Biological and Medical Research Division, Argonne National Laboratory.

Conceptual Design Report" src="https://digital.library.unt.edu/ark:/67531/metadc283143/thumbnail/"/></a></p><p>The DOE is building a new generation 6-7 GeV Synchrotron Radiation Source known as the Advanced Photon Source (APS) at Argonne National Laboratory. This facility, to be completed in FY 1996, can provide 70 x-ray sources of unprecedented brightness to meet the research needs of virtually all scientific disciplines and numerous technologies. The technological research capability of the APS in the areas of energy, communications and health will enable a new partnership between the DOE and US industry. Current funding for the APS will complete the current phase of construction so that scientists can begin their applications in FY 1996. Comprehensive utilization of the unique properties of APS beams will enable cutting-edge research not currently possible. It is now appropriate to plan to construct additional radiation sources and beamline standard components to meet the excess demands of the APS users. In this APS Beamline Initiative, 2.5-m-long insertion-device x-ray sources will be built on four straight sections of the APS storage ring, and an additional four bending-magnet sources will also be put in use. The front ends for these eight x-ray sources will be built to contain and safeguard access to these bright x-ray beams. In addition, funds will be provided to build standard beamline components to meet scientific and technological research demands of the Collaborative Access Teams. The Conceptual Design Report (CDR) for the APS Beamline Initiative describes the scope of all the above technical and conventional construction and provides a detailed cost and schedule for these activities. The document also describes the preconstruction R & D plans for the Beamline Initiative activities and provides the cost estimates for the required R & D.</p>ANL Technical Support Program for DOE Environmental Restoration and Waste Management Annual Report for October 1991 - September 19922015-08-31T12:37:03-05:00https://digital.library.unt.edu/ark:/67531/metadc283097/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc283097/"><img alt="ANL Technical Support Program for DOE Environmental Restoration and Waste Management Annual Report for October 1991 - September 1992" title="ANL Technical Support Program for DOE Environmental Restoration and Waste Management Annual Report for October 1991 - September 1992" src="https://digital.library.unt.edu/ark:/67531/metadc283097/thumbnail/"/></a></p><p>Management (EM) to evaluate factors that are anticipated to affect waste glass reaction during repository disposal, especially in an unsaturated environment typical of what may be expected for the proposed Yucca Mountain repository site.</p>Argonne National Laboratory-East Site Environmental Report for Calendar Year 19922015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc283085/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc283085/"><img alt="Argonne National Laboratory-East Site Environmental Report for Calendar Year 1992" title="Argonne National Laboratory-East Site Environmental Report for Calendar Year 1992" src="https://digital.library.unt.edu/ark:/67531/metadc283085/thumbnail/"/></a></p><p>This report discusses the results of the environmental protection program at Argonne National Laboratory-East (ANL) for 1992.

To increase the intensity of the neutron beams from the IPNS, the target uranium was changed from depleted uranium to uranium enriched to 77.5% U-235. To keep the multiplication factor, k(sub eff) (number of fissions in one generation/number of fissions in preceding generation) at a safe level, a new neutron absorber material was needed. The previous materials, boral and cadmium, could not meet the new requirements and a search of the literature showed that no currently available material was acceptable.</p>Surveillance of Site A and Plot M : Report for 19902015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc283034/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc283034/"><img alt="Surveillance of Site A and Plot M : Report for 1990" title="Surveillance of Site A and Plot M : Report for 1990" src="https://digital.library.unt.edu/ark:/67531/metadc283034/thumbnail/"/></a></p><p>The results of the environmental surveillance program conducted at Site A/Plot M in the Palos Forest Preserve area for CY 1990 are presented.

The primary effect of the radiation field was the acidification of the leachate through the production of nitrogen acids. Acidification of the leachate was limited by bicarbonate in the groundwater, for all exposures tested. Nonirradiated experiments were performed to represent the lowest limit of radiation exposure. Both irradiated and nonirradiated experiments were performed with and without a tuff monolith present in the reaction vessel. Neither irradiation nor the presence of tuff had a major effect on the extent of glass reaction as measured by the leachate concentrations of various glass species or analysis of the reacted glass surfaces. This report discusses the results of leaching experiments performed in a gamma radiation field and in the absence of a radiation field.</p>Two-Phase Flow Patterns and Frictional Pressure Gradients in a Small, Horizontal, Rectangular Channel2015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc283012/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc283012/"><img alt="Two-Phase Flow Patterns and Frictional Pressure Gradients in a Small, Horizontal, Rectangular Channel" title="Two-Phase Flow Patterns and Frictional Pressure Gradients in a Small, Horizontal, Rectangular Channel" src="https://digital.library.unt.edu/ark:/67531/metadc283012/thumbnail/"/></a></p><p>Two-phase flow patterns and frictional pressure gradients in flow in small, rectangular channels are being studies as part of a larger research program addressing phase-change heat transfer of pure refrigerants and refrigerant mixtures in plate-fin heat exchangers. Small rectangular flow channels were selected as representative of plain fin geometries. The particular channel reported herein has dimensions of 19.05 {times} 3.18 mm. Adiabatic flows of air/water mixtures, with the flow channel horizontal and the channel exit at near-atmospheric conditions, were utilized in the experiments. Analysis and interpretation of the pressure data relative to observed flow pattern transitions led to an objective method for determining the plug/bubble-to-slug flow transition. This method, together with visual observations, supplemented with photographic data, was used to develop a flow pattern man. A comparison of existing flow pattern maps for circular pipes, capillary tubes, and larger rectangular channels led to the conclusion that, while qualitative agreement exists, these maps are not generally applicable on a quantitative basis to the subject small rectangular channel. Two state-of-the-art correlations for frictional pressure gradient were evaluated, with particular emphasis on the practically important ranges of total mass quality and mass flux, from the standpoint of plate-fin heat exchangers designed as evaporators. Neither correlation was in good agreement over the entire range of interest. A modified, semi-empirical correlation was developed to predict, with satisfactory accuracy for design purposes, the measured data of these experiments.</p>AC-DC Difference Calibrations2017-03-30T23:32:08-05:00https://digital.library.unt.edu/ark:/67531/metadc502605/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc502605/"><img alt="AC-DC Difference Calibrations" title="AC-DC Difference Calibrations" src="https://digital.library.unt.edu/ark:/67531/metadc502605/thumbnail/"/></a></p><p>Abstract: This publication collects and summarizes the specialized information needed to operate the ac-dc difference laboratory and calibration service at NIST (Gaithersburg).

Bettis is determining the end-of-life (EOL) inventory of fissile uranium in the LWBR core by nondestructive assay of a statistical sample comprising approximately 500 EOL fuel rods. This determination is being made with an irradiated-fuel assay gauge based on neutron interrogation and detection of delayed neutrons from each rod. The EOL fissile inventory will be compared with the beginning-of-life fissile loading of the LWBR to determine the extent of breeding. In support of the BAPL proof-of-breeding (POB) effort, Argonne National Laboratory (ANL) carried out destructive physical, chemical, and radiometric analyses on 17 EOL LWBR fuel rods that were previously assayed with the nondestructive gauge. The ANL work included measurements on the intact rods; shearing of the rods into pre-designated contiguous segments; separate dissolution of each of the more than 150 segments; and analysis of the dissolver solutions to determine each segment's uranium content, uranium isotopic composition, and loading of selected fission products. This report describes the facilities in which this work was carried out, details operations involved in processing each rod, and presents a comprehensive discussion of uncertainties associated with each result of the ANL measurements.</p>X-ray Computed Tomography for Structural Ceramic Applications : Beam Hardening Corrections2015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc282830/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc282830/"><img alt="X-ray Computed Tomography for Structural Ceramic Applications : Beam Hardening Corrections" title="X-ray Computed Tomography for Structural Ceramic Applications : Beam Hardening Corrections" src="https://digital.library.unt.edu/ark:/67531/metadc282830/thumbnail/"/></a></p><p>Beam hardening (BH), caused by the energy dependence of x-ray attenuation in materials, reduces the reliability of images generated by computed tomographic (CT) when polychromatic x-ray sources are used.

The dual-energy approach appears to be a promising means of BH correction for CT imaging of ceramics.</p>Environmental Research Division Technical Progress Report: January 1984-December 19852015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc282786/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc282786/"><img alt="Environmental Research Division Technical Progress Report: January 1984-December 1985" title="Environmental Research Division Technical Progress Report: January 1984-December 1985" src="https://digital.library.unt.edu/ark:/67531/metadc282786/thumbnail/"/></a></p><p>Report on technical progress in the various research and assessment activities of Argonne National Laboratory.</p>Interactive FORTRAN Programs for Micro Computers to Calculate the Thermophysical Properties of Twelve Fluids (MIPROPS)2017-03-15T12:42:30-05:00https://digital.library.unt.edu/ark:/67531/metadc502600/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc502600/"><img alt="Interactive FORTRAN Programs for Micro Computers to Calculate the Thermophysical Properties of Twelve Fluids (MIPROPS)" title="Interactive FORTRAN Programs for Micro Computers to Calculate the Thermophysical Properties of Twelve Fluids (MIPROPS)" src="https://digital.library.unt.edu/ark:/67531/metadc502600/thumbnail/"/></a></p><p>From abstract: The thermophysical and transport properties of selected fluids have been programmed in FORTRAN 77 which is available for micro computers.

This program uses well documented equations to compute these parameters for gain-standard antennas used in relative-gain or gain-transfer measurements at frequencies below 1000 MHz. The utility of this program is that it calculates gain patterns and input impedances for linear dipoles above perfect or imperfectly conducting plane ground and in free space, and for monopoles on perfectly conducting plane ground. Examples are included to illustrate the use of the program. Uncertainties in the calculated parameters are estimated to be less than those of the measured parameters.</p>
