Report on Explosives Repository Testing
Repositories have been in use at Lawrence Livermore National Laboratories for storage of ten grams or less explosives samples for about twenty years. A previous Repository testing program detailed in UCID 19219 reported that a standard repository would contain ten grams of high explosive but the repository drawer would open. It further recommended a non-propagating array that would allow storage of quantities of explosives in a repository drawer, however; the capability of the proposed nonpropagating array was never verified. A series of tests was undertaken to verify the capability of the proposed array to provide non-propagation between 10-gram samples stored within that array and to document the extent of damage to the stored explosives, the array and the repository. Testing has verified that the standard four-drawer repository configured per UCID 19219 may store a 10-gram explosive sample without propagation to the other materials stored in the repository. Should a detonation of a 10-gram sample occur, the four-drawer repository will be damaged but does not appear to create a significant fragment hazard and does not sustain significant damage. The drawer containing the test charge opens quickly and fully releasing the detonation overpressure. Testing of a standard two-drawer repository verified that the …

BRAHMS RESULTS IN THE CONTEXT OF SATURATION AND QUANTUM EVOLUTION.
We report BRAHMS results from RHIC d+Au and p+p collisions at {radical}S{sub NN} = 200GeV. A remarkable change in the nuclear modification factor R{sub dAu} is seen as the pseudorapidity of the detected charged hadrons changes from zero at mid-rapidity to 3.2 at the most forward angle studied during the 2003 run. For pseudorapidity {eta} > 1 the suppression of the R{sub cp} factor is more pronounced in the sample of central events in contrast to the behavior at mid-rapidity where the central events show higher enhancement compared to a semi-central sample. These results are consistent with a saturated Au wave function strongly affected by quantum evolution at higher values of rapidity.

An Evaluation of the Potential for Creep of 3013 Inner Can Lids
This report provides the technical basis to conclude that creep induced deformation of Type 304L austenitic stainless steel can lids on inner 3013 containers will be insignificant unless the temperature of storage exceeds 400 C. This conclusion is based on experimental literature data for Types 304 and 316 stainless steel and on a phenomenological evaluation of potential creep processes.

Associated Higgs Boson Production With Heavy Quarks.
The production of a Higgs boson in association with a pair of e quarks will play a very important role at both hadron and lepton colliders. We review the status of theoretical predictions and their relevance to Higgs boson studies, with particular emphasis on the recently calculated NLO QCD corrections to the inclusive cross section for p{bar p}, pp {yields} t{bar t}h. We conclude by briefly discussing the case of exclusive b{bar b}h production and the potential of this process in revealing signals of new physics beyond the Standard Model.

Oral History Interview with Norman Delisle, March 15, 2001
The National Museum of the Pacific War presents an oral interview with Norman Delisle. Delisle enlisted in the Navy right after Pearl Harbor and went to basic training in Newport, Rhode Island. He was assigned to the Boston Navy Yard awaiting assignment and while there he went to Wentworth Institute for training on diesel engines and air conditioning. After 2-3 months of training, he was transferred back down to Newport and he was made a gunnery instructor, instructing crews from different ships that were anywhere near the area. He was there about eight months and transferred to Vallejo, California to pick up the USS Oakland but before he could report aboard he was diagnosed with rheumatic fever, spending many months in hospitals. They were going to give him a disability discharge but he wanted to go back to active duty which he was allowed to do. He reported to the USS Oakland at Mare Island Shipyard. The Oakland left Mare Island in October, went to Pearl Harbor and joined the Pacific Fleet. The Oakland was involved in the invasion bombardment of Tarawa in the Gilbert Islands and then came back to Hawaii. After Hawaii, the Oakland joined Task Force 38 …

Methodology Used for Total System Performance Assessment of the Potential Nuclear Waste Repository at Yucca Mountain (USA)
The U.S. Department of Energy and its contractors are currently evaluating a site in Nevada (Yucca Mountain) for disposal of high-level radioactive waste from U.S. commercial nuclear plants and U.S. government-owned facilities. The suitability of the potential geologic repository is assessed, based on its performance in isolating the nuclear waste from the environment. Experimental data and models representing the natural and engineered barriers are combined into a Total System Performance Assessment (TSPA) model [1]. Process models included in the TSPA model are unsaturated zone flow and transport, thermal hydrology, in-drift geochemistry, waste package degradation, waste form degradation, engineered barrier system transport, saturated zone flow and transport, and biosphere transport. Because of the uncertainty in the current data and in the future evolution of the total system, simulations follow a probabilistic approach. Multiple realization simulations using Monte Carlo analysis are conducted over time periods of up to one million years, which estimates a range of possible behaviors of the repository. The environmental impact is measured primarily by the annual dose received by an average member of a critical population group residing 20 km down-gradient of the potential repository. In addition to the nominal scenario, other exposure scenarios include the possibility of …

Analysis of background distributions of metals in the soil at Lawrence Berkeley National Laboratory
As part of its Resource Conservation and Recovery Act (RCRA) Corrective Action Program (CAP), the Lawrence Berkeley National Laboratory (LBNL) Environmental Restoration Program conducted an evaluation of naturally occurring metals in soils at the facility. The purpose of the evaluation was to provide a basis for determining if soils at specific locations contained elevated concentrations of metals relative to ambient conditions. Ambient conditions (sometimes referred to as 'local background') are defined as concentrations of metals in the vicinity of a site, but which are unaffected by site-related activities (Cal-EPA 1997). Local background concentrations of 17 metals were initially estimated by LBNL using data from 498 soil samples collected from borings made during the construction of 71 groundwater monitoring wells (LBNL 1995). These concentration values were estimated using the United States Environmental Protection Agency's (USEPA's) guidance that was available at that time (USEPA 1989). Since that time, many more soil samples were collected and analyzed for metals by the Environmental Restoration Program. In addition, the California Environmental Protection Agency (Cal-EPA) subsequently published a recommended approach for calculating background concentrations of metals at hazardous waste sites and permitted facilities (Cal-EPA 1997). This more recent approach differs from that recommended by the USEPA …

Towards the Standardization of a MATLAB-Based Control Systems Laboratory Experience for Undergraduate Students
This paper seeks to begin a discussion with regard to developing standardized Computer Aided Control System Design (CACSD) tools that are typically utilized in an undergraduate controls laboratory. The advocated CACSD design tools are based on the popular, commercially available MATLAB environment, the Simulink toolbox, and the Real-Time Workshop toolbox. The primary advantages of the proposed approach are as follows: (1) the required computer hardware is low cost, (2) commercially available plants from different manufacturers can be supported under the same CACSD environment with no hardware modifications, (3) both the Windows and Linux operating systems can be supported via the MATLAB based Real-Time Windows Target and the Quality Real Time Systems (QRTS) based Real-Time Linux Target, and (4) the Simulink block diagram approach can be utilized to prototype control strategies; thereby, eliminating the need for low level programming skills. It is believed that the above advantages related to standardization of the CACSD design tools will facilitate: (1) the sharing of laboratory resources within each university (i.e., between departments) and (2) the development of Internet laboratory experiences for students (i.e., between universities).

A Cross-Platform Infrastructure for Scalable Runtime Application Performance Analysis
The purpose of this project was to build an extensible cross-platform infrastructure to facilitate the development of accurate and portable performance analysis tools for current and future high performance computing (HPC) architectures. Major accomplishments include tools and techniques for multidimensional performance analysis, as well as improved support for dynamic performance monitoring of multithreaded and multiprocess applications. Previous performance tool development has been limited by the burden of having to re-write a platform-dependent low-level substrate for each architecture/operating system pair in order to obtain the necessary performance data from the system. Manual interpretation of performance data is not scalable for large-scale long-running applications. The infrastructure developed by this project provides a foundation for building portable and scalable performance analysis tools, with the end goal being to provide application developers with the information they need to analyze, understand, and tune the performance of terascale applications on HPC architectures. The backend portion of the infrastructure provides runtime instrumentation capability and access to hardware performance counters, with thread-safety for shared memory environments and a communication substrate to support instrumentation of multiprocess and distributed programs. Front end interfaces provides tool developers with a well-defined, platform-independent set of calls for requesting performance data. End-user tools have …

Application of Monte Carlo Chord-Length Sampling Algorithms to Transport Through a 2-D Binary Stochastic Mixture
Monte Carlo algorithms are developed to calculate the ensemble-average particle leakage through the boundaries of a 2-D binary stochastic material. The mixture is specified within a rectangular area and consists of a fixed number of disks of constant radius randomly embedded in a matrix material. The algorithms are extensions of the proposal of Zimmerman et al., using chord-length sampling to eliminate the need to explicitly model the geometry of the mixture. Two variations are considered. The first algorithm uses Chord-Length Sampling (CLS) for both material regions. The second algorithm employs Limited Chord Length Sampling (LCLS), only using chord-length sampling in the matrix material. Ensemble-average leakage results are computed for a range of material interaction coefficients and compared against benchmark results for both accuracy and efficiency. both algorithms are exact for purely absorbing materials and provide decreasing accuracy as scattering is increased in the matrix material. The LCLS algorithm shows a better accuracy than the CLS algorithm for all cases while maintaining an equivalent or better efficiency. Accuracy and efficiency problems with the CLS algorithm are due principally to assumptions made in determining the chord-length distribution within the disks.

Determining Application Runtimes Using Queueing Network Modeling
Determination of application times-to-solution for large-scale clustered computers continues to be a difficult problem in high-end computing, which will only become more challenging as multi-core consumer machines become more prevalent in the market. Both researchers and consumers of these multi-core systems desire reasonable estimates of how long their programs will take to run (time-to-solution, or TTS), and how many resources will be consumed in the execution. Currently there are few methods of determining these values, and those that do exist are either overly simplistic in their assumptions or require great amounts of effort to parameterize and understand. One previously untried method is queuing network modeling (QNM), which is easy to parameterize and solve, and produces results that typically fall within 10 to 30% of the actual TTS for our test cases. Using characteristics of the computer network (bandwidth, latency) and communication patterns (number of messages, message length, time spent in communication), the QNM model of the NAS-PB CG application was applied to MCR and ALC, supercomputers at LLNL, and the Keck Cluster at USF, with average errors of 2.41%, 3.61%, and -10.73%, respectively, compared to the actual TTS observed. While additional work is necessary to improve the predictive capabilities of …

Detention of American Citizens as Enemy Combatants
This report provides background information regarding the cases of two U.S. citizens deemed “enemy combatants,” Yaser Esam Hamdi, who has been returned to Saudi Arabia, and Jose Padilla, who remains in military custody. The report addresses the constitutional and statutory sources that arguably provide authority for the detention of enemy combatants, as well as those that may prevent the exercise of that power with respect to U.S. citizens. The report concludes that historically, even during declared wars, additional statutory authority has been seen as necessary to validate the detention of citizens not members of any armed forces, casting in some doubt the argument that the power to detain is necessarily implied by an authorization to use force. Finally, the report briefly analyzes the Detention of Enemy Combatants Act, H.R. 1029, which would authorize the President to detain U.S. citizens and residents who are determined to be “enemy combatants” in certain circumstances.
