The final goal of this project was the development of a system that is capable of controlling an industrial process effectively through the integration of information obtained through intelligent sensor fusion and intelligent control technologies. The industry of interest in this project was the metal casting industry as represented by cupola iron-melting furnaces. However, the developed technology is of generic type and hence applicable to several other industries. The system was divided into the following four major interacting components: 1. An object oriented generic architecture to integrate the developed software and hardware components @. Generic algorithms for intelligent signal analysis and sensor and model fusion 3. Development of supervisory structure for integration of intelligent sensor fusion data into the controller 4. Hardware implementation of intelligent signal analysis and fusion algorithms

This paper shows a numerical evaluation of fuels and additives for HCCl combustion. First, a long list of candidate HCCl fuels is selected. For all the fuels in the list, operating conditions (compression ratio, equivalence ratio and intake temperature) are determined that result in optimum performance under typical operation for a heavy-duty engine. Fuels are also characterized by presenting Log(p)-Log(T) maps for multiple fuels under HCCl conditions. Log(p)-Log(T) maps illustrate important processes during HCCl engine operation, including compression, low temperature heat release and ignition. Log(p)-Log(T) diagrams can be used for visualizing these processes and can be used as a tool for detailed analysis of HCCl combustion. The paper also includes a ranking of many potential additives. Experiments and analyses have indicated that small amounts (a few parts per million) of secondary fuels (additives) may considerably affect HCCl combustion and may play a significant role in controlling HCCl combustion. Additives are ranked according to their capability to advance HCCl ignition. The best additives are listed and an explanation of their effect on HCCl combustion is included.

This report discusses about the Homeland Security on Protecting Airliners from Terrorist Missiles where Recent events have focused attention on the threat that terrorists with shoulder fired surface-to-air missiles (SAMs) pose to commercial airliners. Most believe that no single solution exists to effectively mitigate this threat.

Facilities Disposition Projects (FDP) personnel at Savannah River Site (SRS) implement the Inactive Facility Risk Management Program to drive down risk and costs in SRS inactive facilities. The program includes cost-effective techniques to identify and dispose of hazardous chemicals and radioactive waste from inactive facilities, thereby ensuring adequate protection of the public, workers and the environment. In June 1998, FDP conducted an assessment of the inactive C-Reactor Facility to assure that chemical and radiological hazards had been identified and were being safely managed. The walkdown identified the need to mitigate a significant hazard associated with storing approximately 13,400 gallons of liquid radioactive Zinc Bromide in three aging railcar tankers outside of the facility. No preventive maintenance was being performed on the rusting tankers and a leak could send radioactive Zinc Bromide into an outfall and offsite to the Savannah River. In 2001, DOE-Savannah River (DOE- SR) funded the FDP to eliminate the identified hazard by disposing of the radioactive Zinc Bromide solution and the three contaminated railcar tankers. This paper describes the innovative, cost-effective approaches and technology used to perform the first stabilization and disposal of radioactive Zinc Bromide at SRS.

The discharge parameters in Hall thrusters depend strongly on the yield of secondary electron emission from channel walls. Comparative measurements of the yield of secondary electron emission at low energies of primary electrons were performed for several dielectric materials used in Hall thrusters with segmented electrodes. The measurements showed that at low energies of primary electrons the actual energetic dependencies of the total yield of secondary electron emission could differ from fits, which are usually used in theoretical models. The observed differences might be caused by electron backscattering, which is dominant at lower energies and depends strongly on surface properties. Fits based on power or linear laws are relevant at higher energies of primary electrons, where the bulk material properties play a decisive role.

Appropriations are one part of a complex federal budget process that includes budget resolutions, appropriations (regular, supplemental, and continuing) bills, rescissions, and budget reconciliation bills. This report is a guide to one of the 13 regular appropriations bills that Congress considers each year. It is designed to supplement the information provided by the House and Senate Defense Appropriations Subcommittees.

This project focuses on the synthesis of mesoporous aluminophosphate and aluminosilicates as catalysts for application in the conversion of large petroleum feedstock compounds to useful middle distillates and naphtha transportation fuels. Summarized herein, is our research progress for September 1, 2001 to August 31, 2002. The synthesis of aluminophosphates in the presence of nonionic surfactants and block co-polymers were explored over a wide range of synthesis variables such as temperature, Al/P ratio, pH and surfactants/polymer concentrations. In most cases, the resulting products were found to be amorphous. A partially ordered aluminophosphate mesophase was obtained in the presence of Brij 56 non-ionic surfactant. Further characterization to determine the phase type (e.g. hexagonal lamellar or cubic) of this product is pending. The amorphous nature of the products obtained using these classes of surfactants are in contrast to highly ordered aluminophosphates mesophases obtained in the presence of cationic quaternary ammonium surfactants, such as cetyltrimethylammonium detailed in a previous report. The synthesis of pure-silica and aluminosilicate mesophases of different type and quality were also conducted over a wide range of variables such as temperature, Si/Al ratio, pH and surfactants/polymer concentrations. However characterization of the phase type and quality of the materials produced is pending …

A glass bonded-sodalite ceramic waste form (CWF) has been developed to immobilize salt wastes from electrometallurgical treatment of sodium-bonded spent nuclear fuel. The CWF is a composite of salt-loaded sodalite and a binder glass formed at high temperature (850-950 C) by hot isostatic pressing (HIP) or pressureless-consolidation (PC) processes. A waste form degradation and radionuclide release model has been developed to support qualification of the CWF for disposal in the proposed repository at Yucca Mountain. Six series of tests were conducted in conjunction with the development of that model. (1) Static tests were conducted to measure the dissolution rate of sodalite, HIP binder glass, and HIP CWF at 40, 70, and 90 C in pH range 4.8-9.8 buffer solution. The parameter values in the degradation model were calculated from the dissolution rates measured by the static tests. (2) Static tests were conducted at 70 C in noncomplexing tertiary amine pH buffers to confirm that the dissolution rate measured with traditional buffers was not affected by the complexation of metal ions. The results showed that the difference between dissolution rate determined with noncomplexing buffer and that determined with traditional buffers was negligible. (3) Static tests were conducted in five buffer solutions …

“Falun Gong,” also known as “Falun Dafa,”1 combines an exercise regimen with meditation and moral tenets. The “Falun Gong” movement has led to the largest and most protracted public demonstrations in China since the democracy movement of 1989. On April 25, 1999, an estimated 10,000 to 30,000 adherents assembled in front of Zhongnanhai, the Chinese Communist Party leadership compound, and participated in a silent protest against state repression of their activities. On July 21, 1999, the People’s Republic of China (PRC) government, fearful of the spread of social unrest, outlawed the movement and began to arrest Falun Gong protesters.
