3D visualization for the MARS14 Code (open access)

3D visualization for the MARS14 Code

A new three-dimensional visualization engine has been developed for the MARS14 code system. It is based on the OPENINVENTOR graphics library and integrated with the MARS built-in two-dimensional Graphical-User Interface, MARS-GUI-SLICE. The integrated package allows thorough checking of complex geometry systems and their fragments, materials, magnetic fields, particle tracks along with a visualization of calculated 2-D histograms. The algorithms and their optimization are described for two geometry classes along with examples in accelerator and detector applications.

Access to Government Information In the United States (open access)

Access to Government Information In the United States

The Constitution of the United States makes no specific allowance for any one of the co-equal branches to have access to information held by the others and contains no provision expressly establishing a procedure for, or a right of, public access to government information. Nonetheless, Congress has legislated various public access laws. These include two records access statutes — the Freedom of Information Act and the Privacy Act — and two meetings access statutes — the Federal Advisory Committee Act and the Government in the Sunshine Act. This report provides background on the issue of government transparency and examines relevant litigation.

Access to Government Information in the United States

The Constitution of the United States makes no specific allowance for any one of the co-equal branches to have access to information held by the others and contains no provision expressly establishing a procedure for, or a right of, public access to government information. Nonetheless, Congress has legislated various public access laws. These include two records access statutes—the Freedom of Information Act (5 U.S.C. 552) and the Privacy Act (5 U.S.C. 552a)—and two meetings access statutes—the Federal Advisory Committee Act (5 U.S.C. App.) and the Government in the Sunshine Act (5 U.S.C. 552b). Moreover, due to the American separation of powers model of government, interbranch conflicts over the accessibility of information are neither unexpected nor necessarily destructive. The federal courts, historically, have been reluctant to review and resolve “political questions” involving information disputes between Congress and the executive branch. Although there is considerable interbranch cooperation, such conflicts probably will continue to occur on occasion.

Accurate modeling of cache replacement policies in a Data-Grid. (open access)

Accurate modeling of cache replacement policies in a Data-Grid.

Caching techniques have been used to improve the performance gap of storage hierarchies in computing systems. In data intensive applications that access large data files over wide area network environment, such as a data grid,caching mechanism can significantly improve the data access performance under appropriate workloads. In a data grid, it is envisioned that local disk storage resources retain or cache the data files being used by local application. Under a workload of shared access and high locality of reference, the performance of the caching techniques depends heavily on the replacement policies being used. A replacement policy effectively determines which set of objects must be evicted when space is needed. Unlike cache replacement policies in virtual memory paging or database buffering, developing an optimal replacement policy for data grids is complicated by the fact that the file objects being cached have varying sizes and varying transfer and processing costs that vary with time. We present an accurate model for evaluating various replacement policies and propose a new replacement algorithm referred to as ''Least Cost Beneficial based on K backward references (LCB-K).'' Using this modeling technique, we compare LCB-K with various replacement policies such as Least Frequently Used (LFU), Least Recently …

Armenia, Azerbaijan, and Georgia: Political Developments and Implications for U.S. Interests (open access)

Armenia, Azerbaijan, and Georgia: Political Developments and Implications for U.S. Interests

The United States recognized the independence of all the former Soviet republics by the end of 1991, including the South Caucasus states of Armenia, Azerbaijan, and Georgia. The United States has fostered these states' ties with the West in part to end the dependence of these states on Russia for trade, security, and other relations. The FREEDOM Support Act of 1992 provides authorization for assistance to the Eurasian states for humanitarian needs, democratization, and other purposes. In the aftermath of the September 11, 2001, terrorist attacks on the United States, the Administration appealed for a national security waiver of the prohibition on aid to Azerbaijan, in consideration of Azerbaijan's assistance to the international coalition to combat terrorism. Azerbaijani and Georgian troops participate in stabilization efforts in Afghanistan and Iraq, and Armenian personnel serve in Iraq.

Chemical Plant Security (open access)

Chemical Plant Security

Facilities handling large amounts of potentially hazardous chemicals (i.e., chemical facilities) might be of interest to terrorists, either as targets for direct attacks meant to release chemicals into the community or as a source of chemicals for use elsewhere. Because few terrorist attacks have been attempted against chemical facilities in the United States, the risk of death and injury in the near future is estimated to be low, relative to the likelihood of accidents at such facilities or attacks on other targets using conventional weapons. For any individual facility, the risk is very small, but risks may be increasing with potentially severe consequences for human health and the environment. Available evidence indicates that many chemical facilities may lack adequate safeguards.

China and Proliferation of Weapons of Mass Destruction and Missiles: Policy Issues (open access)

China and Proliferation of Weapons of Mass Destruction and Missiles: Policy Issues

Congress has long been concerned about whether U.S. policy advances the national interest in reducing the role of the People's Republic of China (PRC) in the proliferation of weapons of mass destruction (WMD) and missiles that could deliver them. China has taken some steps to mollify U.S. concerns about its role in weapons proliferation. Skeptics question whether China's cooperation in weapons nonproliferation has warranted President Bush's pursuit of stronger bilateral ties. This report discusses the national security problem of China's role in weapons proliferation and issues related to the U.S. policy response, including legislation, since the mid-1990s.

Classical Least Squares Transformations of Sensor Array Pattern Vectors into Vapor Descriptors (open access)

Classical Least Squares Transformations of Sensor Array Pattern Vectors into Vapor Descriptors

A new method of processing multivariate response data to extract chemical information has been developed. Sensor array response patterns are transformed into a vector containing values for solvation parameter descriptors of the detected vapor's properties. These results can be obtained by using a method similar to classical least squares, and equations have been derived for mass-transducing sensors or volume-transducing sensors. Polymer-coated acoustic wave devices are an example of mass-transducing sensors. However, some acoustic wave sensors, such as polymer-coated surface acoustic wave (SAW) devices give responses resulting from both mass-loading and decreases in modulus. The latter effect can be modeled as a volume effect. In this paper we derive solutions for obtaining descriptor values from arrays of mass-plus-volume-transducing sensors. Simulations were performed to investigate the effectiveness of these solutions and to compare them with solutions for purely mass-transducing sensor arrays. It is concluded that this new method of processing sensor array data can be applied to SAW sensor arrays even when the modulus changes contribute to the responses. The simulations show that good estimations of vapor descriptors can be obtained by using a closed form estimation approach that is similar to the closed form solution for purely mass-transducing sensor arrays. Estimations …

Documenting the Effectiveness of Cosorption of Airborne Contaminants by a Field-Installed Active Desiccant System: Final Report - Phase 2D (open access)

Documenting the Effectiveness of Cosorption of Airborne Contaminants by a Field-Installed Active Desiccant System: Final Report - Phase 2D

The final report for Phase 1 of this research effort (ORNL/SUB/94-SV004/1) concluded that a significant market opportunity would exist for active desiccant systems if it could be demonstrated that they can remove a significant proportion of common airborne contaminants while simultaneously performing the primary function of dehumidifying a stream of outdoor air or recirculated building air. If the engineering community begins to follow the intent of ASHRAE Standard 62, now part of all major building codes, the outdoor air in many major cities may need to be pre-cleaned before it is introduced into occupied spaces. Common air contaminant cosorption capability would provide a solution to three important aspects of the ASHRAE 62-89 standard that have yet to be effectively addressed by heating, ventilation, and air-conditioning (HVAC) equipment manufacturers: (1) The ASHRAE standard defines acceptable outdoor air quality. If the outdoor air contains unacceptable levels of certain common outdoor air contaminants (e.g., sulfur dioxide, ozone), then the standard requires that these contaminants be removed from the outdoor air stream to reach compliance with the acceptable outdoor air quality guidelines. (2) Some engineers prefer to apply a filtration or prescriptive approach rather than a ventilation approach to solving indoor air quality problems. …
