A Comparison of Inexact Newton and Coordinate Descent Meshoptimization Technqiues (open access)

A Comparison of Inexact Newton and Coordinate Descent Meshoptimization Technqiues

We compare inexact Newton and coordinate descent methods for optimizing the quality of a mesh by repositioning the vertices, where quality is measured by the harmonic mean of the mean-ratio metric. The effects of problem size, element size heterogeneity, and various vertex displacement schemes on the performance of these algorithms are assessed for a series of tetrahedral meshes.

Creep of Nearly Lamellar TiAl Alloy Containing W (open access)

Creep of Nearly Lamellar TiAl Alloy Containing W

Effects of W on the creep resistance of two nearly fully lamellar TiAl alloys with 1.0 and 2.0 at.%W have been investigated. In the low stress regime (LS) a nearly quadratic (1.5<n<2) creep behavior was observed. It is found that the addition of W can improve the creep resistance; however, the addition of excess W can result in the formation of {beta} phase, which produces an adverse effect on the creep strength.

Defects in p-GaN and their atomic structure (open access)

Defects in p-GaN and their atomic structure

In this paper defects formed in p-doped GaN:Mg grown with Ga polarity will be discussed. The atomic structure of these characteristic defects (Mg-rich hexagonal pyramids and truncated pyramids) in bulk and thin GaN:Mg films grown with Ga polarity was determined at atomic resolution by direct reconstruction of the scattered electron wave in a transmission electron microscope. Small cavities were present inside the defects. The inside walls of the cavities were covered by GaN which grew with reverse polarity compared to the matrix. It was proposed that lateral overgrowth of the cavities restores matrix polarity on the defect base. Exchange of Ga and N sublattices within the defect compared to the matrix lead to a 0.6 {+-} 0.2 {angstrom} displacement between the Ga sublattices of these two areas. A [1{und 1}00]/3 shift with change from AB stacking in the matrix to BC within the entire pyramid is observed

Defense Trade: Issues Concerning the Use of Offsets in International Defense Sales (open access)

Defense Trade: Issues Concerning the Use of Offsets in International Defense Sales

Testimony issued by the Government Accountability Office with an abstract that begins "Views on defense offsets range from beliefs that they are both positive and an unavoidable part of doing business overseas to beliefs that they negatively affect the U.S. industrial base. Defense offsets are often viewed as the key to foreign sales and thus increased business on the prime contractor level. They can also result in reduced unit costs to the U.S. military because of the increased size of production runs. However, the use of a foreign supplier by a U.S. prime contractor as a result of an offset may lead to decreased business opportunities for U.S. suppliers. Additionally, U.S. prime contractors may develop long-term relationships with foreign suppliers, which may lead to the transfer of capability from the U.S. defense industrial base. As a result of congressional concerns about emerging trends in defense offsets, GAO conducted a number of reviews and issued multiple reports. Because of GAO's work in this area, Congress asked us to provide our observations on offset issues. Specifically, GAO is providing observations on (1) what constitutes offsets and how they are used in defense trade, (2) how that use has changed over time, and …

Department of Defense: Financial and Business Management Transformation Hindered by Long-standing Problems

Testimony issued by the Government Accountability Office with an abstract that begins "GAO has previously reported on the Department of Defense's (DOD) financial management and business related problems and key elements necessary for successful reform. Although the underlying conditions remain fundamentally unchanged, DOD continues to be confronted with pervasive problems related to its systems, processes (including internal controls), and people (human capital). These problems impede DOD's ability to operate its numerous business operations in an efficient and effective manner. Congress asked GAO to provide its views on (1) the impact that long-standing financial management and related business process weaknesses continue to have on DOD, (2) the underlying causes of DOD business transformation challenges, and (3) DOD's business transformation efforts. In addition, GAO reiterates the key elements to successful reform: (1) an integrated business management transformation strategy, (2) sustained leadership and resource control, (3) clear lines of responsibility and accountability, (4) results-oriented performance measures, (5) appropriate incentives and consequences, (6) an enterprise architecture to guide reform efforts, and (7) effective monitoring and oversight."

Department of Homeland Security: Financial Management Challenges

Testimony issued by the Government Accountability Office with an abstract that begins "The Homeland Security Act of 2002 brought together 22 agencies to create a new cabinet-level department focusing on reducing U.S. vulnerability to terrorist attacks, and minimizing damages and assisting in recovery from attacks that do occur. GAO has previously reported on the Department of Homeland Security's (DHS) financial management challenges and key elements necessary for reform. DHS continues to be faced with significant financial management challenges, including addressing existing internal control weaknesses and integrating redundant inherited financial management systems. Additionally, DHS is the largest entity in the federal government that is not subject to the Chief Financial Officers (CFO) Act of 1990 or the Federal Financial Management Improvement Act (FFMIA) of 1996. In light of these conditions, Congress asked GAO to testify on the financial management challenges facing DHS."

Depot Maintenance: Army Needs Plan to Implement Depot Maintenance Report's Recommendations (open access)

Depot Maintenance: Army Needs Plan to Implement Depot Maintenance Report's Recommendations

A letter report issued by the General Accounting Office with an abstract that begins "Each year, the U.S. Army spends about $3 billion on depot-level maintenance and repair work for weapons systems and other equipment. However, because its data gathering and reporting processes have been limited, the Army historically has been unable to fully identify how much depotlevel maintenance takes place outside its five public depots. As a result, it has not been able to determine with precision how well it was meeting statutory requirements to limit contracted depot-level maintenance work to 50 percent of the program budget. In the House report on the Fiscal Year 2001 Defense Authorization Act, Congress directed the Army to report on the proliferation of depot-level maintenance work at nondepot facilities and asked GAO to review that report. GAO examined the extent to which (1) the Army's report identifies the amount of depot-level maintenance work done outside public depots; (2) the Army can account for its depot-level maintenance workload, as required by statute; and (3) the corrective actions in the report are likely to address the proliferation issue and enhance the Army's reporting."

Deterministic, Nanoscale Fabrication of Mesoscale Objects (open access)

Deterministic, Nanoscale Fabrication of Mesoscale Objects

Neither LLNL nor any other organization has the capability to perform deterministic fabrication of mm-sized objects with arbitrary, {micro}m-sized, 3-D features and with 100-nm-scale accuracy and smoothness. This is particularly true for materials such as high explosives and low-density aerogels, as well as materials such as diamond and vanadium. The motivation for this project was to investigate the physics and chemistry that control the interactions of solid surfaces with laser beams and ion beams, with a view towards their applicability to the desired deterministic fabrication processes. As part of this LDRD project, one of our goals was to advance the state of the art for experimental work, but, in order to create ultimately a deterministic capability for such precision micromachining, another goal was to form a new modeling/simulation capability that could also extend the state of the art in this field. We have achieved both goals. In this project, we have, for the first time, combined a 1-D hydrocode (''HYADES'') with a 3-D molecular dynamics simulator (''MDCASK'') in our modeling studies. In FY02 and FY03, we investigated the ablation/surface-modification processes that occur on copper, gold, and nickel substrates with the use of sub-ps laser pulses. In FY04, we investigated laser …

Development of a Quantitative Approach to Incorporating Stakeholder Values into Total Maximum Daily Loads: Dominguez Channel Case Study (open access)

Development of a Quantitative Approach to Incorporating Stakeholder Values into Total Maximum Daily Loads: Dominguez Channel Case Study

The federal Clean Water Act (CWA) Section 303(d)(1)(A) requires each state to conduct a biennial assessment of its waters, and identify those waters that are not achieving water quality standards. The result of this assessment is called the 303(d) list. The CWA also requires states to establish a priority ranking for waters on the 303(d) list of impaired waters and to develop and implement Total Maximum Daily Loads (TMDLs) for these waters. Over 30,000 segments of waterways have been listed as impaired by the Environmental Protection Agency (EPA). The EPA has requested local communities to submit plans to reduce discharges by specified dates or have them developed by the EPA. An investigation of this process found that plans to reduce discharges were being developed based on a wide range of site investigation methods. The Department of Energy requested Lawrence Livermore National Laboratory to develop appropriate tools to assist in improving the TMDL process. The EPA has shown support and encouragement of this effort. Our investigation found that improving the stakeholder input process would facilitate many of the TMDL processes, given the resources available to the interested and responsible parties. The first model that we have developed is a stakeholder allocation …

Development of a Real-Time Radiological Area Monitoring Network for Emergency Response at Lawrence Livermore National Laboratory (open access)

Development of a Real-Time Radiological Area Monitoring Network for Emergency Response at Lawrence Livermore National Laboratory

A real-time radiological sensor network for emergency response was developed and deployed at the Lawrence Livermore National Laboratory (LLNL). The Real-Time Radiological Area Monitoring (RTRAM) network is comprised of 16 Geiger-Mueller (GM) sensors positioned on the LLNL Livermore site perimeter to continuously monitor for a radiological condition resulting from a terrorist threat to site security and the health and safety of LLNL personnel. The RTRAM network sensor locations coincide with wind sector directions to provide thorough coverage of the one square mile site. These low-power sensors are supported by a central command center (CCC) and transmit measurement data back to the CCC computer through the LLNL telecommunications infrastructure. Alarm conditions are identified by comparing current data to predetermined threshold parameters and are validated by comparison with plausible dispersion modeling scenarios and prevailing meteorological conditions. Emergency response personnel are notified of alarm conditions by automatic radio and computer based notifications. A secure intranet provides emergency response personnel with current condition assessment data that enable them to direct field response efforts remotely. The RTRAM network has proven to be a reliable system since initial deployment in August 2001 and maintains stability during inclement weather conditions.

Disruptive Event Biosphere Dose Conversion Factor Analysis (open access)

Disruptive Event Biosphere Dose Conversion Factor Analysis

This analysis report is one of the technical reports containing documentation of the Environmental Radiation Model for Yucca Mountain, Nevada (ERMYN), a biosphere model supporting the total system performance assessment (TSPA) for the license application (LA) for the Yucca Mountain repository. This analysis report describes the development of biosphere dose conversion factors (BDCFs) for the volcanic ash exposure scenario, and the development of dose factors for calculating inhalation dose during volcanic eruption. A graphical representation of the documentation hierarchy for the ERMYN is presented in Figure 1-1. This figure shows the interrelationships among the products (i.e., analysis and model reports) developed for biosphere modeling and provides an understanding of how this analysis report contributes to biosphere modeling. This report is one of two reports that develop biosphere BDCFs, which are input parameters for the TSPA model. The ''Biosphere Model Report'' (BSC 2004 [DIRS 169460]) describes in detail the ERMYN conceptual model and mathematical model. The input parameter reports, shown to the right of the Biosphere Model Report in Figure 1-1, contain detailed descriptions of the model input parameters, their development and the relationship between the parameters and specific features, events and processes (FEPs).
