The objective of the proposed project is to develop innovative new analytical instrumentation and methodology capable of performing fully automated, non-destructive analysis of semiconductor sensor elements and arrays locate on three inch diameter wafers. The instrumentation would be capable of analyzing II-VI compounds and alloys, particularly HgCdTe. The methodology would employ state-of-the-a ...

ENVIRONMENTAL STRESS SCREENING (ESS) IS THE TAILORED APPLICATION OF ENVIRONMENTAL STRESSES TO MANUFACTURED END ITEMS TO IDENTIFY AND ELIMINATE DEFECTIVE, ABNORMAL, OR MARGINAL PARTS AND MANUFACTURING DEFECTS. THE APPLICATION OF ESS TO ONE-SHOT ORDNANCE DEVICES LIKE FUZES, SAFE/ARMING DEVICES AND TIMERS IS COMPLICATED AND TOO OFTEN IGNORED OR INEFFECTUAL. THIS PROPOSAL SHOWS A WAY OF RELATING ESS P ...

TO MEET THE KINETIC ENERGY ANTI-SATELLITE (KE ASAT) REQUIREMENTS FOR TIMELY AND RELIABLE KILL ASSESSMENT, AEROMET PROPOSES TO RECOMMEND INNOVATIVE TECHNIQUES IN REAL-TIME KILL ASSESSMENT SPECTROSCOPY. BECAUSE IT CAN BE CRITICALLY IMPORTANT TO ACCURATELY VERIFY SATELLITE ELIMINATION, A KILL ASSESSMENT SYSTEM MUST DISCERN BETWEEN VARIOUS HIT AND MISS PHENOMENA, INCLUDING THE USE OF POTENTIAL COUNTER ...

MANY COMPELLING EIS/ESS APPLICATIONS IN THE MILITARY AND IN INDUSTRY REMAIN INFEASIBLE DUE TO LIMITATIONS IN COMPUTER TECHNOLOGY. MANY INTERESTING PROBLEMS ARE TOO LARGE OR TOO COMPLEX FOR PRACTICAL SOLUTIONS BY TRADITIONAL APPROACHES. THE COMPLEXITY MAY ARISE FROM UNKNOWN, NON-LINEAR, OR TIME-VARYING RELATIONSHIPS BETWEEN VARIABLES. NEURAL NETWORK TECHNOLGY HAS DEMONTRATED SIGNIFICANT CAPABAILITI ...

This effort will integrate an advanced technology speech recognition system (SRS) with a computer-assisted contingency planning training model. The SRS makes use of algorithms developed in the Speech Technology and Research Labratory of SRI International. Its state-of-the-art approach provides significant improvements in accuracy and robustness over other approaches. It provides for speaker ind ...

THIS PROPOSAL DESCRIBES AN APA OPTICS PROGRAM TO DEVELOP A HIGH SPEED (100GHZ) GAAS WAVEGUIDE BASED MACH ZEHNDER MODULATOR. OUR APPROACH CENTERS ON THE USE OF A BURIED ELECTRODE CONFIGURATION TO ACHIEVE VELOCITY MATCHING OF THE RF AND OPTICAL SIGNALS. THIS WE FEEL WILL RESULT IN A DEVICE WITH A BROADBAND RESPONSE FROM DC TO 100GHZ. WE WILL WORK IN CONJUNCTION WITH THE ULTRFAST SCIENCE LAB AT THE U ...

BASED UPON EARLIER EXPERIMENTAL WORK, IT WAS DISCOVERED THAT ULTRASONIC RADIATION OF THE PROPER FREQUENCY WOULD PRECIPITATE SMOKE AND AEROSOLS WITHIN THE RADIATION PATTERN. THE PURPOSE OF THIS EFFORT IS TO EXPERIMENTALLY PROVE THE FEASIBILITY OF USING THE CONCEPT TO CLEAR SMOKE AND AEROSOLS FROM A BATTLEFIELD. TWO SPECIFIC APPLICATIONS WILL BE STUDIED, 1) TO CREATE A SMALL AREA OF CLEAR AIR TO TAR ...
