Mission Research Corporation proposes the development of a unique FPGA (field programmable gate array) for applications in space and other military and civilian environments requiring the versatility of reconfigurability with retention of the configuration in an unpowered state. The FPGA will be capable of being configured once and retaining that configuration for a minimum of 10 years even with ...

THE INTENT OF DOD INSTRUCTION 4245.4, "ACQUISITION OF NUCLEAR SURVIVAL SYSTEMS" IS TO PROVIDE FOR NUCLEAR SURVIVABILITY THROUGHOUT THE LIFE CYCLE OF WEAPON SYSTEMS WHICH ARE REQUIRED TO SURVIVE THE EFFECTS OF NUCLEAR WEAPONS. ONE KEY TO IMPLEMENTING THIS INTENT IS TO INSURE THAT ALL THE PEOPLE INVOLVED ARE FAMILIAR WITH THEIR RESPONSIBILITIES TO IMPLEMENT AND PRESERVE THIS SURVIVABILITY. THIS STUD ...

The recent DNA-sponsored conference on ¿Verification and Validation of Nonlinear Structural Dynamic Codes,¿ September 1993, highlighted the need for reliable models as well as codes. At the present time there are no generally available software tools for utilizing experimental data to correct and refine models implemented on general-purpose codes such as DYNA3D. Nor are there tools available f ...

One of the Operation Directorate's top ten challenges is the development of handheld gas chromatography (GC) instrumentation for CW treaty verification. Toward this challenge, DNA has recently developed and reduced to practice innovative new technologies for low power, fast GC. An unsolved technical issue which still remains with small, portable GC devices is how to conduct fast and automated va ...

THE VERY POLITICALLY SENSITIVE NATURE OF NUCLEAR WARFARE WOULD PRESUPPOSE THAT THE ABILITY OF THE COMMANDER TO PLAN FOR THE USE OF WEAPONS OF THIS TYPE WOULD CREATE THE NEED FOR A METHOD WHICH WOULD BE AS FOOL-PROOF AS POSSIBLE. EARLY WEAPONS WERE DESIGNATED STRATEGIC WEAPONS WHILE LATER DEVELOPED WEAPONS WERE CALLED TACTICAL. IT WAS WITH THE EVOLUTION TO TACTICAL WEAPONS THAT EXTENSIVE POSITIVE C ...

THE DEFENSE NUCLEAR AGENCY SEEKS NEW INSTRUMENTATION USING STATEOF-THE-ART TECHNOLOGY FOR IMPROVED DATA COLLECTION WITH BETTER ACCURACY AT LOWER COST. LARGE AMOUNTS OF DATA MUST BE RECORDED TO CHARACTERIZE THE EFFECTS OF NUCLEAR WEAPONS TESTS. QUANSCAN PROPOSES TO APPLY CONCEPTS RECENTLY PROVEN FOR THE SCANNING TUNNELING MICROSCOPE TO STUDY THE FEASIBILITY OF DEVELOPING A NEAR SOLID STATE MASS STO ...

CURRENT ATTEMPTS TO USE THE PLASMA OPENING SWITCH (POS) FOR DECADE HAVE NOT YET BEEN ENTIRELY SUCCESSFUL DUE TO THE APPARENT INABILITY OF THE SWITCH TO OPEN EFFICIENTLY TO A HIGH-IMPEDENCE LOAD. RESEARCH DIRECTED TOWARD IMPROVING THE PERFORMANCE OF THE POS IN THE LONG-CONDUCTION TIME REGIME HAS BEEN FRUSTRATED BY THE INABILITY OF COMPUTATIONAL TOOLS TO OPERATE IN THE PARAMETER REGIMES OF INTEREST ...

THE ADVANCE OF TECHNOLOGIES MAY MAKE DEFENSE AGAINST BALLISTIC MISSLES TECHNICALLY AND ECONOMICALLY FEASIBLE. A NATIONAL POLICY DEBATE HAS BEGUN ON THE DESIRABILITY OF MAKING A TRANSITION FROM STRATEGIC DETERRANCE TO STRATEGIC DEFENSE. THE DEBATE IS AT PRESENT HIGHLY CONFUSING AND UNSTRUCTURED, SINCE THE VARIOUS ARGUMENTS FOR AND AGAINST THAT TRANSITION ARE BASED ON DIFFERING ASSUMPTIONS, OFTEN TA ...
