A NEW DESIGN CONCEPT FOR ELECTRONIC SHELTERS USING SOME OF THE ADVANCED MATERIALS SUCH AS CONDUCTIVE COMPOSITES, AND REINFORCED CONDUCTIVE SILICONE FABRICS WILL BE TESTED. THE MOST RELEVENT APPLICATION PARAMETERS SUCH AS CONDUCTIVITY OF THE COMPOSITES AND FABRICS, THE JOINING MECHANISM TO ENSURE ELECTROMAGNETIC COMPATIBILITY, THE FLEXIBILITY, THE TRANSPORTABILITY AND TOTAL SYSTEM WEIGHT WILL BE AD ...

WAFER PROBING IS THE CRITICAL LINK BETWEEN WAFER FABRICATION, AND DEVICE PACKAGING OR HYBRID SUBSYSTEM INSERTION. FOR GAAS MMICS TO BE COST EFFECTIVE, THEY MUST BE TESTED IN A MANNER THAT IS RELIABLE, FAST, AND EFFICIENT. THIS PROPOSAL DESCRIBES A PROGRAM TO DEVELOP EQUIPMENT AND TECHNIQUES FOR HIGH RATE, HIGH VOLUME MMIC WAFER PROBING. PHASE I OF THIS PROGRAM WILL INCLUDE AN EXPERIMENT USING EXIS ...

Under Phase I effort, Applied Thin Films, Inc. (ATFI) discovered a new process to deposit oxide buffer layers for HTS coated conductors that is economical, scalable, and has demonstrated excellent performance with YBCO films (current densities of 1MA/cm2). The process is called ECONO (Epitaxial Conversion to Oxide via Nitride Oxidation) which is now being considered as the primary contender for t ...

THE VAPOR SPACE INSIDE AN AIRCRAFT FUEL TANK EITHER IS OR IS NOT FLAMMABLE (OR EXPLOSIVE) DEPENDING UPON THE PERCENTAGE OF FUEL VAPOR AND OF OXYGEN OF INERT GAS SUCH AS NITROGEN OR CARBON DIOXIDE. IT IS IMPORTANT TO KNOW THESE PERCENTAGES WHEN TESTING THE EFFICACY OF EXPERIMENTAL INERTING MEASURES BY FIRING LIVE ROUNDS AT TEST TANKS; BUT THERE IS NO FAST, CONVENIENT, FIELD METHOD OF MEASURING THE ...

WE SHALL DEVELOP METHODS TO SOLVE ONE OF THE CRITICAL PROBLEMS OF TURBULENCE MODELLING IN WHICH ALL TRADITIONALLY USED TURBULENCE MODELS FAIL, NAMELY MODELLING OF MIXING AND CHEMICAL REACTIONS IN COMPLEX TURBULENT FLOWS. WE PROPOSE TO DEVELOP A THREE-DIMENSIONAL COMPUTER CODE INCORPORATING RENORMALIZATION-GROUP (RNG) BASED DIFFERENTIAL TRANSPORT MODELS FOR TURBULENT HEAT, MASS, MOMENTUM TRANSFER C ...

THE OBJECTIVE OF THIS WORK IS TO INVESTIGATE THE UTILITY OF COMPUTATIONAL FLUID DYNAMIC (CFD) MODELS TO SIMULATE REACTIONS WITHIN FLUID-FILLED TANKS IMPACTED BY WARHEAD FRAGMENTS. IN PHASE I, WE WILL DEVELOP A TWO-DIMENSIONAL (CYLINDRICAL GEOMETRY) MODEL WHICH CONTAINS THE SALIENT PHYSICAL FEATURES NECESSARY TO PARAMETRIZE THE COMPLEX PROCESSES ASSOCIATED WITH FRAGEMENT IMPACT ON FUEL TANKS. WE US ...
