THE LONG TERM OBJECTIVE OF THIS PROJECT IS TO PROVIDE AN INTERACTIVE TRAINING SYSTEM FOR NONSPEAKING CHILDREN AND ADULTS. THE COMPUTER-DRIVEN SYSTEM CAN BE CONCEPTUALIZED AS A FLEXIBLE HARDWARE CONFIGURATION WHICH CAN BE PERSONALIZED FOR EACH CHILD'S INPUT/OUTPUT NEEDS AND WHICH "OPENS THE DOOR" TO EXISTING ASSISTIVE TECHNOLOGIES. A MENU-DRIVEN SHELL, CONTROLLED BY THE CHILD OR CLINICIAN, WILL ALL ...

THIS PROJECT IS DESIGNED TO DEVELOP A COMPUTERIZED DATA COLLECTION SYSTEM FOR EARLY INTERVENTION PROGRAMS UTILIZING HARDWARE COMMONLY AVAILABLE WITHIN EACH EARLY INTERVENTION CENTER SITE. PARALLEL DATABASE SYSTEMS WILL BE DEVELOPED FOR THREE HARDWARE PLATFORMS, ALL WITH THE ABILITY TO TRANSFER DATA INTO A CENTRAL MICRO-COMPUTER. THREE HARDWARE PLATFORMS ARE COMMONLY USED IN EARLY INTERVENTION SITE ...

AN EXPERIMENTAL INVESTIGATION OF INNOVATIVE FLAMEHOLDER DESIGNS TO ENHANCE MIXING IN A SUPERSONIC COMBUSTION RAMJET (SCRAMJET) ENGINE IS PROPOSED. IN A SCRAMJET ENGINE OPERATING AT HYPERSONIC FLIGHT SPEEDS,THE SHORTER RESIDENCE TIME AND DECREASED MIXING RATE CAUSE DETERIORATION IN THE COMBUSTION EFFICIENCY AS COMPARED WITH LOWER SPEEDS. TWO CONFIGURATIONS RECENTLY DEVELOPED TO PROMOTE RAPID MIXING ...

THE PROTECTION OF OPTICAL/IR SENSORS OF HUMAN EYES AGAINST LASER THREATS IS AN IMPORTANT UNSOLVED DEFENSE PROBLEM. THE MOST CHALLENGING NEED IS FOR AN OPTICAL LIMITER WITH PICOSECOND RESPONSE IN A FINITE WAVELENGTH BAND AGAINST SHORT PULSE, FREQUENCY-AGILE LASERS. OUR RESEARCH IS DIRECTED TOWARDS DEVICE APPLICATIONS OF NOVEL NONLINEAR OPTICAL LIQUIDS WITH PRECISE INDEX MATCHING PROPERTIES AND LARG ...

HEAVY, MULTI-PLY, LIMITED LIFE LIGHTER-THAN-AIR (LTA) VEHICLE SKINS COULD BE REPLACED WITH A HIGH STRENGTH/TOUGH, GAS IMPERMEABLE 2-PLY ORDERED POLYMER LAMINATE. THIS WOULD RESULT IN FACTORS OF 3 TO 10 REDUCTION IN LTA VEHICLE OR SKIN WEIGHT, WHICH WOULD TRANSLATE LINEARLY TO GREATER PAYLOAD AND RELATED PERFORMANCE. THE PROPOSED PHASE I PROGRAM WILL DEVELOP AN EFFICIENT, RELIABLE AND SIMPLE-TOFABR ...

THE INNOVATION WE PROPOSE IS A NOVEL PRECERAMIC POLYMER ROUTE TO THIN (< 1U) COATINGS OF NITRIDES AND CARBIDES ON GRAPHITE FIBERS TO BE USED IN TITANIUM ALUMINIDE INTERMETALLIC COMPOSITES. IF SUCCESSFUL, THE COATINGS WILL PROVIDE AN EFFECTIVE BARRIER TO FIBER-MATRIX REACTION AT HIGH PROCESSING AND SERVICE TEMPERATURES - A MAJOR CAUSE OF DEGRADATION IN THESE NEW HIGH TEMPERATURE COMPOSITES. THE COA ...

IN A CONVENTIONAL WAR, NEUTRALIZATION OF OPPOSING ARMOR IS A KEY MILITARY OBJECTIVE. TRADITIONALLY, SUCH ACTION IS ACHIEVED BY FIREPOWER. HOWEVER, OTHER METHODS (SOFT-KILL) ARE ALSO AVAILABLE; THESE METHODS HAVE THE ADVANTAGE THAT THEY DO NOT HAVE TO OVERCOME THE PROTECTIVE ARMOR OF OPPOSING COMBAT VEHICLES AND OTHER FIELDED WEAPONS. THE WORK PROPOSED HEREIN IS AIMED AT INVESTIGATING A WIDE RANGE ...
