A MAJOR PROBLEM WITH CURRENTLY AVAILABLE CHEMICAL AGENT FILTERS IS THE RESISTENCE TO AIR PERMEABILITY, OR BREATHABILITY. THIS RESISTANCE IS DUE TO THE RELATIVELY DENSE PACKING OF ACTIVATED CARBON MATERIAL TO ABSORB THE TOXIC CHEMICAL VAPORS. A PROGRAM IS PROPOSED TO DEVELOP ACTIVATED CARBON FIBER FELTX THAT POSSES LOW FIBER DENSITY TO ACHIEVE GOOD AIR PERMEABILITY, BUT ADEQUATE VAPOR ABSORPTION. T ...

A PROPOSAL IS PRESENTED HEREIN TO INITIATE AN ANALYTIC STUDY OF THE FLOW FIELD RESULTING FROM THE INTERACTION OF AN UNSTEADY SHOCK WAVE WITH THE GROUND AND ABOVE GROUND STRUCTURES. THE LONG TERM GOAL OF THIS ANALYSIS WILL BE TWOFOLD, (1) PREDICT THE PRESSURE PULSE ON STRUCTURES AND (2) PREDICT THE FLOW FIELD DUE TO THE PROPAGATION OF A SHOCK WAVE ALONG THE GROUND AND THE RESULTANT DUST ENTRAINMENT ...

ATTAINABLE COMPUTATION RATES ONCOMPUTERS WITH SERIAL ARCHITECTURE ARE A SERIOUS LIMITATION FOR THE SIMULATION OF THE HYDRODYNAMIC BEHAVIOR OF FLUIDS. COMPUTERS WITH PARALLEL PROCESSING ARCHITECTURE CAN ACHIEVE MUCH HIGHER RATES. THE COMPUTER RESEARCH AND APPLICA TIONS GROUP AT LOS ALAMOS NATIONAL LABORATORIES IS MAKING THEIR DENELCOR HEP COMPUTER AVAILABLE FOR RESEARCH PROJECTS CONDUCTED BY OTHER ...

SIGNIFICANT SAVINGS IN COST AND DISPLACEMENT OF VALUABLE PETROLEUM FUEL CAN BE ACHIEVED BY BURNING COAL WHEN APPROPRIATE FOR DOD POWER GENERATION REQUIREMENTS. THIS PROPOSAL OFFERS A COST EFFECTIVE, PORTABLE, COMPUTER CONTROLLED AND INTEGRATED COAL ANALYSIS SYSTEM FOR ASSESSING A COAL'S COMBUSTION PERFORMANCE. THE PROPOSED SYSTEM FOR COAL ANALYSES IS AN INTEGRATED THERMOGRAVIMETER ANALYZER (TGA), ...

LOW-COST CIG SIMULATORS FOR WEAPONS TRAINING COULD BE PRODUCED THROUGH THE USE OF VLSI CHIPS SPECIFICALLY DESIGNED TO CARRY OUT THE MAJOR FUNCTIONS OF IMAGE GENERATION, NAMELY 3-D PERSPECTIVE, DIFFUSE REFLECTION AND SHADING, HIDDEN SURFACE REMOVAL AND OCCULTATION IN GENERAL, CLIPPING AND AREA FILL. THESE CHIPS WILL BE FAST ENOUGH TO ALLOW COMPUTATION AT 60 FRAMES/SEC WITH A RESOLUTION OF 1024 X 10 ...

THIS PROPOSED STUDY WILL EXAMINE THE FEASIBILITY OF USING A EULERIAN LIMITED AREA MODEL (LAM) TO IMPROVE PREDICTION OF CHEMICAL, BIOLOGICAL, AND OBSCURANT CLOUDS DURING AMPHIBIOUS OPERATIONS. THE LAM HAS BEEN USED TO PREDICT MESOSCALE AND MICROSCALE METEORO LOGICAL PHENOMENA FOR A WIDE VARIETY OF CLIMATIC REGIMES AND HAS BEEN TESTED FOR A NUMBER OF EXTENSIVE METEOROLOGICAL FIELD EXPERIMENTS. THE L ...

METHYLENE BIS O-CHLORO ANILINE HAS LONG BEEN RECOGNIZED AS A SUPERIOR URETHANE CURATIVE BUT TOXICITY CONCERNS HAVE LIMITED ITS USE. ALTERNATIVE COMPOUNDS ARE AVAILABLE, BUT THEY CANNOT MATCH THE HANDLING AND ULTIMATE PHYSICAL PROPERTIES OF MOCA CURED ELASTOMERS. AN INVESTIGATIONS OF NOVEL PLYAMINE AND POLYOL COMPOUNDS SHOULD YIELD NEW AND USEFUL URETHANE CURATIVES. THE PROGRAM WOULD IN VOLVE SCREE ...
