ABSTRACT:A cooperative small business and university research and development program is proposed to begin development of a robust, non-contacting, digital image correlation based, full-field strain measurement system for high temperature applications. The Phase I studies will demonstrate that a robust high temperature digital image correlation system (HTDICS) can be developed that is capable of a ...

As NASA space missions become longer in duration the need for high efficiency power generator sets that can operate on NASA logistical fuel become critical. Historically NASA has used fuel cells as part of the energy solution. Space bound energy and power systems require rapid start and stop cycle times as well as high power densities. The high operational efficiency, coupled with the use of logi ...

Advanced reconfigurable/reprogrammable communication systems will require use of commercial sub 100 nm electronics. Legacy radiation tolerant circuits fail to provide Single Event Upset (SEU) immunity at speeds greater than 500 MHz. New base level logic circuits are needed to provide SEU immunity for high speed circuits afforded by sub 100 nm technology. A completely new circuit and system appr ...

ABSTRACT: This Small Business Technology Transfer Phase I project will address the problem of obtaining low-defect-density gallium nitride single crystals for substrates to enable low-defect, high-performance epitaxial growth. Gallium nitride is a very promising material for numerous applications including surface acoustic wave devices, high-powered LEDs, UV diode lasers and high-powered RF devic ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: The Space Plug-and-play Avionics (SPA) initiative is designed to improve the ability of the US military to respond to rapidly changing operational needs by creating, integrating, and launching a new spacecraft in less than one week. This would provide major benefits to war fighters on the ground, in the sky, and at sea. SPA-1 ASICs using I2C as the transport interface will likely be t ...

THE COMPLETE DESIGN IS PRESENTED WITHIN THIS PROPOSAL FOR A SYSTEM WHICH WILL PROVIDE A PRECISE, ONE-STEP CONVERSION DIRECTLY FROM A PULSE TRAIN INPUT TO A DIGITIZED PULSE RATE OUTPUT. IT IS A DISTRIBUTED PROCESSOR SYSTEM EMPLOYING A MASTER CONTROL PROCESSOR AND FROM 2 TO 30 IDENTICAL PULSE MODULES. THE PULSE MODULE IS A STANDALONE UNIT WHICH PERFORMS THE PULSE PERIOD MEASUREMENT. THE MICROPROCESS ...

THE HOSTILE ENVIRONMENT EXISTING AT THE BORE SURFACE OF GUN BARRELS USED IN HIGH RATE OF FIRE AIRCRAFT CANNONS PRESENTS A FORMIDABLE DESIGN CHALLENGE TO THE GUN DESIGNER. HEAT, FRICTION, CORROSION AND WEAR AT THE BORE SURFACE ACT IN UNISON TO RAPIDLY DETERIORATE THE BORE. CHROME PLATING IS PRESENTLY THE ONLY COST EFFECTIVE METHOD OF IMPROVING BORE SURFACE LIFE. PLASMA SURFACE ALLOYING IS AN EMERGI ...
