ADVANCED MISSILE AND REENTRY VEHICLE SYSTEMS FOR WHICH INCREASED NUCLEAR HARNESS REQUIREMENTS WILL BE IMPOSED CURRENTLY HAVE NO CLEAR CUT SOLUTION AS TO HOW THEY WILL SUSTAIN THE INCREASED REQUIREMENTS. VOLUMETRIC, WEIGHT, AND SYSTEM PERFORMANCE CONSTRAINTS MAKE "BRUT FORCE" HARDENING DESIGN SOLUTIONS UNACCEPTABLE AND COSTLY. THE OBJECTIVE OF THIS PHASE I STUDY IS TO REVIEW AND CORRELATE THE RESUL ...

Generally, it is accepted that for plastics recycling to be economically viable in the long term, recycled resins must be competitive with virgin resins. To compete with virgin material, new applications must be made available for recycled resins. Such applications will require that the recycled resin be of a high purity level. Thus, many processors are requiring ever-tightening contamination limi ...

IN THE LAST TWO YEARS, THERE HAVE BEEN INCREASING CONCERNS ABOUT THE POTENTIALLY LARGE COOLING OF THE LAND SURFACE TEMPERATURE RESULTING FROM THE SOOT AND DUST INJECTED INTO THE ATMOSPHERE BY THE EXPLOSIONS AND SECONDARY FIRES FROM NUCLEAR EXCHANGES, THE SO-CALLED "NUCLEAR WINTER" SCENARIOS. HERE WE ARGUE THAT, IN ADDITION TO DUST AND SOOT, A LARGE NUMBER OF TRACE GASES (NO[X], H[2]0, HC, CH[4]) C ...

Upon successful completion of the proposed program, an accelerant payload concept shall be developed and evaluated. The use of an accelerant payload allows the munitions system designer the capability to exploit a thermal target defeat mechanism, inaddition to coupling to traditional high explosive/fragmentation defeat mechanisms, to increase the overall target lethality. The use of a thermal ac ...

CONVENTIONAL NUCLEAR HARDENING AND SURVIVABILITY COMPUTER CODES ARE CURRENTLY IMPLEMENTED ON LARGE MAINFRAME COMPUTER SYSTEMS SUCH AS THE CRAY, IBM, AND THE VAX. TRANSFERRING THESE CODES TO A PERSONAL COMPUTER COULD PROVIDE A MUCH MORE EFFICIENT OPERATING SYSTEM ENVIRONMENT IN THAT SIMPLE ENERGY DEPOSITION ANALYSES FOR EXAMPLE COULD BE PERFORMED "ON-SITE" AND THE COSTS ASSOCIATED WITH FILE STORAGE ...

The task of computationally simulating the dispersion and/or neutralization of toxic chemical/biological (CB) agents, released from weapons of mass destruction (WMD), puts a very high demand on the capability of current generation computational dynamics(CFD) codes. Current advanced computational tools for WMD threat simulation fail to address all the necessary physics, do not incorporate emerging ...

COAL TAR IS A BY-PRODUCT OF THE COAL GASIFICATION PROCESS USED WIDELY BETWEEN 1820 AND 1950 TO PRODUCE A NATURAL GAS SUBSTITUTE. DURING THAT TIME, BILLIONS OF GALLONS OF TAR WERE PRODUCED AT MORE THAN 1500 GAS MANUFACTURING FACILITIESLOCATED THROUGHOUT THE U.S. A LARGE PORTION OF THIS WASTE TAR REMAINS IN STORAGE OR WAS DISPOSED OF BY INJECTION INTO SUBSURFACE SITES. COAL TAR IS A MIXTURE OF HYDRO ...

OPTRA, Inc., is proposing a low-resolution ( 15 nm) Fresnel sapphire split-prism spectrometer specifically tailored to the identification of molecular species present in the emissions from an engine source. The proposed approach will examine the 3-5.5 ¿m spectral region, allowing for the extraction of concentration information of CO2, CO, NO, HCs, and particulate matter. Sapphire was chosen bec ...

Mide Technology Corporation proposes to develop a fuel injection system for automotive combustion control. The design is composed of a fast-acting piezoelectric actuator to operate a fuel injection valve and emission sensors located in the exhaust, both used in concert with a rapid-learning control algorithm to reduce engine NOx, hydrocarbon (HC), and particulate emissions without sacrificing fuel ...
