An interactive application that employs social interactions to teach key social conventions, including appropriate responses, reacting to body language and facial expressions, and the ability to ask for help to facilitate functioning in society

Not Available Virtually every user of launch services is seeking methods to reduce launch costs. A reusable conventional launch vehicle configuration shows the potential to achieve this goal. The LOX/LNG propellant combination shows the potential to enhance both propulsion system reusability and launch system mass-to-orbit capability. This propellant combination also has the performance margins n ...

Not Available The development of advanced communication or electronic warfare systems requires high performance miniaturized microwave filters. Miniaturized high-Q evanescent (EV) is one of the most desirable filters due to its wide stopband and small size, especially for satellite down-converter applications where a few hundred EV filters are used. Currently, EV filters are made using very small ...

Not Available Lightweight structures are demanding for high inach vehicles and engine exhaust impinged structures subjected to high temperatures. Currently used polyimide composites have limited service temperatures whereas titanium alloys have much higher densities than those of advanced composites. This Phase I research proposes the processing of high temperature sandwich structures using micro ...

FEASIBILITY OF USING MICROPROCESSOR BASED PERSONAL TOKEN DEVICES INDUCTIVELY COUPLED FOR BI-DIRECTIONAL INFORMATION FLOW WILL BE STUDIED FOR TRANSIT FARE COLLECTION AND ACCOUNTING. A SIMPLE MICROPROCESSOR BASED USER TOKEN WILL BE DEVELOPED PRINCIPALLY TO TEST COUPLING AND SOFTWARE CONCEPTS. HARDWARE AND SOFTWARE INTERFACES TO EXISTING TURNSTILE EQUIPMENT WILL BE STUDIED. RESEARCH ON APPROPRIATE RE ...

FLAME RETARDANT FLEXIBLE POLYURETHANE FOAM FINDS WIDESPREAD COMMERCIAL USE AS A SEATING MATERIAL DUE TO ITS FAVORABLE COST, SUPPORT, AND RESILIENCE CHARACTERISTICS. HOWEVER, SMOKE AND TOXIC GAS EVOLUTION IN THE EVENT OF FIRE IS A MAJOR PROBLEM. THE GOAL OF THIS PROGRAM IS TO CREATE A FIRE RESISTANT COMPOSITE FOAM STRUCTURE WHICH WILL GENERATE NEGLIGIBLE QUANTITIES OF TOXIC FUMES WHEN EXPOSED TO FI ...

THE PURPOSE OF THIS STUDY IS TO EXAMINE THE EFFECTIVENESS OF LIMITED TEACHER-AUTHORING USING INTERACTIVE LASER VIDEODISCS OPERATING WITH A MICROCOMPUTER TO TEACH EFL AT THE ENTRY LEVEL. THE APPLICATION WILL BE IN A PRE-EMPLOYMENT VOCATIONAL CONTEXT, SIMILAR TO JOB CLUB ENVIRONMENTS. TEACHER-AUTHORING IN PHASE I WILL BE LIMITED TO POST-TREATMENT, STUDENT ASSESSMENT QUESTIONS. PHASE I EQUIPMENT WILL ...
