This Plan is the product of a long-range planning process used to project both future information technology requirements and the resources necessary to meet those requirements. It encompasses the plans of the various organizational components within the Department and its management and operating contractors over the next 5 fiscal years, 1991 through 1995
Space charge in proton linacs( )

2 editions published in 1998 in English and held by 0 WorldCat member libraries worldwide

There are at least two reasons for the interest in space-charge effects in proton linacs. First, it can be expected that there are some areas of commonality in the space-charge physics of linacs and circular machines. Second, a linac delivers the input beam to a circular machine, so understanding the linac physics helps to explain the limitations for the input beam quality to a ring. This presentation is divided into three parts. First, the authors discuss space-charge effects form the linac point of view. Second, they discuss practical methods of calculation of linac beam dynamics that include space-charge forces. Finally, they summarize the status of experimental studies of the beam performance in the LANSCE linac including space-charge effects
Nonlinear dynamics of domain walls and vortices in two-dimensional systems( )

1 edition published in 1989 in English and held by 0 WorldCat member libraries worldwide

We discuss analytic and numerical studies of experimentally accessible 2-dimensional condensed matter systems which support nonlinear domain wall and vortex structures. These systems include quasi-2-dimensional magnets and 2-dimensional arrays of Josephson junctions. We emphasize the importance of these systems for investigating: complex (frustrated) ground states, dynamics (including glassy'' dynamics), interactions between domain walls and vortices, and phase transitions at finite temperature accompanied by these excitations. 16 refs., 3 figs
The effects of user mobility on usage parameter control (UPC) in wireless ATM systems( )

2 editions published in 1997 in English and held by 0 WorldCat member libraries worldwide

Wireless Asynchronous Transfer Mode (WATM) networks pose new traffic management problems. One example is the effect of user mobility on Usage Parameter Control (UPC). If the UPC algorithm resets after each handoff between wireless-cells, then users can cheat on their traffic contract. This paper derives explicit relationships between a user's traffic parameters (Peak Cell Rate, Sustained Cell Rate and Maximum Burst Size), their transit time per wireless-cell, their maximum sustained cheating-rate and the Generic Cell Rate Algorithm's (GCRA's) Limit (L) parameter. It also shows that the GCRA can still effectively police Constant Bit Rate (CBR) traffic, but not some types of realistic Variable Bit Rate (VBR) traffic
Method for rapid, high sensitivity tritiated water extraction( )

2 editions published in 1997 in English and held by 0 WorldCat member libraries worldwide

Routine counting methods and ICP-MS are unable to directly measure the new US Department of Energy (DOE) regulatory level for discharge waters containing alpha-emitting radionuclides of 30 pCi/L total alpha or the 0.05 pCi/L regulatory level for Pu or Am activity required for surface waters at the Rocky Flats site by the State of Colorado. This inability indicates the need to develop rapid, reliable, and robust analytical techniques for measuring actinide metal ions, particularly americium and plutonium. Selective separation or preconcentration techniques would aid in this effort. Water-soluble metal-binding polymers in combination with ultrafiltration are shown to be an effective method for selectively removing dilute actinide ions from acidic solutions of high ionic strength. The actinide-binding properties of commercially available water-soluble polymers and several polymers which have been reported in the literature were evaluated. The functional groups incorporated in the polymers were pyrrolidone, amine, oxime, and carboxylic, phosphonic, or sulfonic acid. The polymer containing phosphonic acid groups gave the best results with high distribution coefficients and concentration factors for ²⁴¹Am(III) and ²³⁸Pu(III)/(IV) at pH 4 to 6 and ionic strengths of 0.1 to 4
Solar oscillation frequency and solar neutrino predictions( )

4 editions published in 1990 in English and held by 0 WorldCat member libraries worldwide

The light and velocity variations of the Sun and solar-like stars are unique among intrinsic variable stars. Unlike all other standard classes, such as Cepheids, B stars, and white dwarfs, the pulsation driving is caused by coupling with the acoustic noise in the upper convection zone. Each global pulsation mode is just another degree of freedom for the turbulent convection, and energy is shared equally between these g⁻-modes and the solar oscillation modes. This driving and damping, together with the normal stellar pulsation mechanisms produce extremely low amplitude solar oscillations. Actually, the surface layer radiative damping is strong, and the varying oscillation mode amplitudes manifest the stochastic convection driving and the steady damping. Thus stability calculations for solar-like pulsations are difficult and mostly inconclusive, but calculations of pulsation periods are as straightforward as for all the other classes of intrinsic variable stars. The issue that is important for the Sun is its internal structure, because the mass, radius, and luminosity are extremely well known. Conventionally, we need the pulsation constants for each of millions of modes. Unknown parameters for constructing solar models are the composition and its material pressure, energy, and opacity, as well as the convection mixing length. We treat the nuclear energy and neutrino production formulas as sufficiently well known. The presence of weakly interacting massive particles (WIMPs) orbiting the solar center affects the predicted oscillation frequencies so that they do not agree with observations as well as those for models without WIMPs. 34 refs., 4 figs
Performance evaluation of the IBM RISC (reduced instruction set computer) System / Comparison of an optimized scalar processor with two vector processors( )

2 editions published in 1990 in English and held by 0 WorldCat member libraries worldwide

RISC System/6000 computers are workstations with a reduced instruction set processor recently developed by IBM. This report details the performance of the 6000-series computers as measured using a set of portable, standard-Fortran, computationally-intensive benchmark codes that represent the scientific workload at the Los Alamos National Laboratory. On all but three of our benchmark codes, the 40-ns RISC System was able to perform as well as a single Convex C-240 processor, a vector processor that also has a 40-ns clock cycle, and on these same codes, it performed as well as the FPS-500, a vector processor with a 30-ns clock cycle. 17 refs., 2 figs., 6 tabs
Optical fabrication and metrology for a visible through thermal infrared multi-band imaging system( )

3 editions published in 1998 in English and held by 0 WorldCat member libraries worldwide

A simulated automobile factory paint shop is used as a testbed for exploring the emulation of human decision making behavior. A discrete events simulation of the paint shop as a collection of interacting Java actors is described. An evolutionary cognitive architecture is under development for building software actors to emulate humans in simulations of human dominated complex systems. In this paper, the cognitive architecture is extended by implementing a persistent population of trial behaviors with an incremental fitness valuation update strategy, and by allowing a group of cognitive actors to share information. A proof of principle demonstration is presented
Performance analysis of multidimensional wavefront algorithms with application to deterministic particle transport( )

4 editions published in 1998 in English and held by 0 WorldCat member libraries worldwide

High-current proton linear accelerators offer an attractive alternative for generating the intense neutron fluxes needed for transmutations technologies, tritium production and neutron science. To achieve the fluxes required for tritium production, a 100-mA, 1700-MeV cw proton accelerator is being designed that uses superconducting cavities for the high-energy portion of the linac, from 211 to 1,700 MeV. The development work supporting the linac design effort is focused on three areas: superconducting cavity performance for medium-beta cavities at 700 MHz, high power rf coupler development, and cryomodule design. An overview of the progress in these three areas is presented
Deformation and fracture of TiAl + W at elevated temperatures( )

3 editions published in 1990 in English and held by 0 WorldCat member libraries worldwide

The ternary alloy, Ti - 49 at% Al -2 at. % W, was produced using Rotating Electrode Powder (REP) compacted by hot extrusion. The tensile properties of this alloy (strength, ductility and fracture mode) were studied from room temperature to 900°C. Constant load creep properties were measured from 700 to 900°C and analyzed using conventional power law equations to calculate the stress exponent and activation energy. These parameters were approximately 4 and 400 KJ/mole respectively. TEM examination showed that the W was held in solid solution during the tensile and creep deformation when the material was tested in the as-extruded' condition. These results are interpreted as evidence for solid solution strengthening of the TiAl matrix by the W solute. 13 refs., 3 figs., 4 tabs
Virtual pinhole confocal microscope( )

1 edition published in 1999 in English and held by 0 WorldCat member libraries worldwide

Scanned confocal microscopes enhance imaging capabilities, providing improved contrast and image resolution in 3-D, but existing systems have significant technical shortcomings and are expensive. Researchers at Los Alamos National Laboratory have developed a novel approach--virtual pinhole confocal microscopy--that uses state of the art illumination, detection, and data processing technologies to produce an imager with a number of advantages: reduced cost, faster imaging, improved efficiency and sensitivity, improved reliability and much greater flexibility. Work at Los Alamos demonstrated proof of principle; prototype hardware and software have been used to demonstrate technical feasibility of several implementation strategies. The system uses high performance illumination, patterned in time and space. The authors have built functional confocal imagers using video display technologies (LCD or DLP) and novel scanner based on a micro-lens array. They have developed a prototype system for high performance data acquisition and processing, designed to support realtime confocal imaging. They have developed algorithms to reconstruct confocal images from a time series of spatially sub-sampled images; software development remains an area of active development. These advances allow the collection of high quality confocal images (in fluorescence, reflectance and transmission modes) with equipment that can inexpensively retrofit to existing microscopes. Planned future extensions to these technologies will significantly enhance capabilities for microscopic imaging in a variety of applications, including confocal endoscopy, and confocal spectral imaging
Can model updating tell the truth?( )

2 editions published in 1998 in English and held by 0 WorldCat member libraries worldwide

This paper presents a comparison of two techniques used to estimate the statistical confidence intervals on modal parameters identified from measured vibration data. The first technique is Monte Carlo simulation, which involves the repeated simulation of random data sets based on the statistics of the measured data and an assumed distribution of the variability in the measured data. A standard modal identification procedure is repeatedly applied to the randomly perturbed data sets to form a statistical distribution on the identified modal parameters. The second technique is the Bootstrap approach, where individual Frequency Response Function (FRF) measurements are randomly selected with replacement to form an ensemble average. This procedure, in effect, randomly weights the various FRF measurements. These weighted averages of the FRFs are then put through the modal identification procedure. The modal parameters identified from each randomly weighted data set are then used to define a statistical distribution for these parameters. The basic difference in the two techniques is that the Monte Carlo technique requires the assumption on the form of the distribution of the variability in the measured data, while the bootstrap technique does not. Also, the Monte Carlo technique can only estimate random errors, while the bootstrap statistics represent both random and bias (systematic) variability such as that arising from changing environmental conditions. However, the bootstrap technique requires that every frequency response function be saved for each average during the data acquisition process. Neither method can account for bias introduced during the estimation of the FRFs. This study has been motivated by a program to develop vibration-based damage identification procedures
Exciton and biexciton signatures in the femtosecond transient absorption of phenylene-based polymers and oligomers( )

2 editions published in 1998 in English and held by 0 WorldCat member libraries worldwide

The femtosecond transient absorption of phenylene-based polymers at low intensities is dominated by singlet excitons. In films, inter-chain excitons are created at high intensities via two-exciton states. In solution, the authors observe signatures of stable biexcitons
Cadmium zinc telluride spectral modeling( )

2 editions published in 1998 in English and held by 0 WorldCat member libraries worldwide

An efficient method for determining the distribution of charge pulses produced by semiconductor detectors is presented. The method is based on a quasi-steady-state model for semiconductor detector operation. A complete description of the model and underlying assumptions is given. Mapping of charge pulses is accomplished by solving an adjoint carrier continuity equation. The solution of the adjoint equation yields Green's function, a time- and position-dependent map that contains all possible charge pulses that can be produced by the detector for charge generated at discrete locations (e.g., by gamma-ray interactions). Because the map is generated by solving a single, time-dependent problem, the potential for reduction in computational effort over direct mapping methods is significant, particularly for detectors with complex electrode structures. In this paper, the adjoint equation is derived and the mapping method is illustrated for a simple case
Proceedings of the ModSim'97 USA workshop. Volumes 1 and 2( )

1 edition published in 1997 in English and held by 0 WorldCat member libraries worldwide

Although application modeling and simulation methodologies are widely recognized to be an essential component of a successful endeavor, this is not generally the case in the area of environmental restoration and waste management. Such methods are used, particularly for risk assessment, but their application to decision making for environmental cleanup and waste management is much less recognized and accepted. In late 1996, the Department of Energy's Office of Science and Technology (DOE/OST) asked the Environmental Management Program Office (Integrated Science and Technology Program) at Los Alamos National Laboratory to host a workshop that would define the future role of modeling and simulation in addressing global and national environmental problems. This workshop would be designed to answer the question of whether modeling and simulation is important to environmental remediation, waste management, and other environmentally-related activities and to make recommendations accordingly
