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 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 ...

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 ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

Physical Optics Corporation (POC)s proposes to develop a neural-optical sensor for biological and chemical (""NOSBC"") weapons, with vapor detection capability. The system will comprise a sensor head and a signal processing/display unit. The NOSBC will simultaneously perform multiple immunoassays with a one-second sensor response time; it will apply biometic fuzzy metrology to these parallel sig ...

The DM1 module that is a building block of DSWA's DECADE simulator has excellent electrical performance, but the final radiation pulse is erratic and often unsatisfactory. The probable cause is a parasitic current in ions, or through a diode plasma. This proposal is to evaluate a diode configuration that should suppress ions and plasma, namely a cathode of carbon fibers covered with cesium iodid ...
