THIS RESEARCH STUDY DEVELOPS AN INTERACTIVE, MICROCOMPUTER-BASED, PICTURE ICON LAYOUT AND AUTHORING SYSTEM FOR EDUCATORS, COMMUNICATIONS SPECIALISTS, AND EDUCATIONAL TECHNOLOGISTS WHO ADAPT OR FABRICATE COMMUNICATIONS AIDS AND SYSTEMS FOR NON-VOCAL OR SPEECH-IMPAIRED CHILDREN OR ADULTS. A PROTOTYPE PICTURE ICON LAYOUT SOFTWARE (PILS) SYSTEM WILL BE DESIGNED FOR THE UNICORN II EXPANDED KEYBOARD (UN ...

METALORGANIC MOLECULAR BEAM EPITAXY (MOMBE) IS A SEMICONDUCTOR GROWTH TECHNIQUE THAT HAS THE POTENTIAL FOR COMBINING THE BEST FEATURES OF MOLECULAR BEAM EPITAXY WITH THOSE OF ORGANOMETALLIC VAPOR PHASE EPITAXY (OMVPE). A MAJOR PROBLEM HINDERING DEVELOPMENT OF MOMBE TECHNIQUES FOR GROWING GROUP III/V SEMICONDUCTORS IS THE AVAILABILITY OF APPROPRIATELY DESIGNED SOURCE REAGENTS THAT PERMIT EFFICIENT ...

FERROELECTRIC MATERIALS SUCH AS BARIUM TITANIUM OXID (BARIO3) HAVE ELECTRO-OPTIC COEFFICIENTS THAT ARE AN ORDER OF MAGNITUDE GREATER THAN THAT OF THE MORE COMMON LITHIUM NIOBIUM OXIDE (LINBO3). THEIR SUPERIOR POTENTIAL HAS NOT BEEN EXPLOITED BECAUSE THE ROUTINE GROWTH OF LARGE DEFECT-FREE OPTICAL QUALITY CRYSTALS HAS NOT BEEN ACHIEVED. IN THIS INVESTIGATION, PLANAR WAVEGUIDES ARE BEING FABRICATED ...

OVER THE PAST DECADE STUDIES HAVE INDICATED THAT IT IS POSSIBLE TO UTILIZE THE ULTRAFAST (PICOSECOND) RESPONSE TIMEOF A PHOTOCONDUCTOR TO DETECT AND TIME RESOLVE THE RAPID VARIATIONS OF LIGHT FROM A RAPIDLY CHANGING SOURCE SUCH AS APULSED LASER, A LASER FUSION EXPERIMENT, A DIRECTED ENERGY WEAPON OR A NUCLEAR WEAPONS EXPLOSION. IN ADDITION TO THE RAPID TEMPORAL EVOLUTION OF THE LIGHT OUTPUT FROM S ...

A RENEWED INTEREST IN THE APPLICATIONS OF SUPERCONDUCTIVITY HAS RESULTED FROM THE RECENT DISCOVERY OF PEROVSKITE-LIKE COPPER-OXIDE SUPERCONDUCTORS WITH TRANSITION TEMPERATURES ABOVE LIQUID NITROGEN TEMPERATURES. ALTHOUGH THE THIN FILMS AS DEPOSITED GENERALLY HAVE THE APPROPRIATE Y:BA:CU STOICHIOMETRY, A SUBSEQUENT HIGH TEMPERATURE (T>900 DEGREE CELCIUS) OXYGEN TREATMENT IS REQUIRED TO ACHIEVE THE ...

PROVISION OF MEANINGFUL INSERVICE TRAINING FOR THE EDUCATORSOF HANDICAPPED CHILDREN IS INCREASINGLY COSTLY AND DIFFICULT TO ADMINISTER. OUTDATED DELIVERY MODELS ARE UNABLE TO PROVIDE FOCUSED CONTENT, AND ARE UNRESPONSIVE TO STAFF REQUIREMENTS. THIS PROPOSAL ADDRESSES THE NEED FOR BETTER INSERVICE TRAINING WITH A DECENTRALIZED, SELF-PACED MODEL THAT PROVIDES FOCUSED CONTENT WITH COMPUTERIZED REVIEW ...

AN APPROACH IS BEING INVESTIGATED FOR THE FLUORINATION OF DIAMOND THIN FILMS FOR TRIBOLOGICAL APPLICATIONS. THE APPROACH USES LOW PRESSURES OF F AND/OR CFX FREE RADICALS. TO DEMONSTRATE THE FEASIBILITY OF THIS APPROACH, DATA IS BEING COLLECTED ON: FLUORINATION KINETICS, THE COMPOSITION AND STRUCTURE OF THE SURFACE AND NEAR SURFACE LAYERS, THE EFFECTS OF TEMPERATURE ON THE FLUORINATION PROCESS, AND ...

AICOM PLANS TO DEVELOP A LOW COST, HIGH QUALITY SPEECH SYNTHESIZER CHIP WHICH MAY BE USED IN THE VISUALLY IMPAIRED MARKET, IN THE EDUCATION MARKET, AND IN THE COMMERCIAL MARKET. IN THIS PHASE, WE PLAN TO STUDY THE ARCHITECTURE OF THE CHIP, THE COMPLEXITY OF THE CIRCUIT, THE POSSIBLE DIE SIZE, THE POWER CONSUMPTION, AND THE TOTAL COST OF PRODUCING THE CHIP. IN ADDITION, WE PLAN ON RUNNING A COMPUTE ...
