AMMONIUM DINITRAMIDE (ADN) WAS INVENTED AT SRI INTERNATIONAL (MENLO PARK, CA) IN 1989. ITS DISCOVERY IS SIGNIFICANT IN THAT THEORETICAL CALCULATIONS PREDICT IT TO EXHIBIT BETTER PERFORMANCE AS AN ADVANCED ORDNANCE MATERIAL THAN MOST CLASSICAL NITRAMINE INGREDIENTS. A PROBLEM WITH ADN AT THE OUTSET WAS THE LOW YIELDS OFFERED BY THE SYNTHETIC ROUTES TO THE COMPOUND. THE MOST IMPORTANT OBJECTIVE OF T ...

THE GOAL OF THIS PROJECT IS TO PRODUCE A SIGN-LANGUAGE TELEPHONE PROVIDING VISUAL COMMUNICATION TO THE HEARING IMPAIRED. CURRENTLY THEIR ONLY ACCESS TO TELEPHONE CONVERSATION IS WITH TYPED MESSAGES USING TELEPHONE FOR THE DEAF AND DISABLED. SIGN-LANGUAGE IS A MORE APPROPRIATE AND EFFECTIVE COMMUNICATION MEDIUM THAN IS WRITTEN ENGLISH. PHYSICAL PROPERTIES OF THE EXISTING TELEPHONE NETWORK PRECLUDE ...

Not Available High power motors and generators can be made very compact when run under cryogenic conditions. For further enhancements in power densities it is highly desirable to use High Temperature Superconductors with a greatly enhanced critical current densigy Jc at 3T at 77K, which would allow the use of liquid nitrogen as a coolant. Under these operating conditions the superconductor YBa2Cu ...

THE PROPOSED PROJECT ADDRESSES THE DESIGN, DEVELOPMENT AND TESTING OF A PROTOTYPE MATHEMATICS PROGRAM EVALUATION ASSESSMENT INSTRUMENT FOR ELEMENTARY SCHOOL MATHEMATICS PROGRAMS. THE PROPOSED ASSESSMENT INSTRUMENT WILL ADDRESS THE NEW STANDARDS FOR MATHEMATICS PROGRAMS THAT WERE ESTABLISHED BY THE NATIONAL COUNCIL OF TEACHERS OF MATHEMATICS AND WILL RELY ON ALTERNATIVE TESTING STRATEGIES TO MORE A ...

FOUR BEARINGLESS, SHAFT MOUNTED GENERATORS WITH OUTPUTS OF 10, 100, 500 AND 1000 WATTS OF 12-15 V DC WILL BE DESIGNED AND COMPUTER MODELED TO BE DRIVEN BY MODEL AIRPLANE SIZE RECIPROCATING ENGINES. DESIGN COMBINATIONS OF IRONLESS DISK AND IRON LAMINATION CYLINDRICAL GENERATORS USING RARE EARTH AND CERAMIC PERMANENT MAGNETS WILL BE MODELED FOR RELIABILITY WITH THE LOWEST WEIGHT AT THE HIGHEST EFFIC ...

THE INDIVIDUALS WITH DISABLILTIES EDUCATION ACT REQUIRES TRANSITION PLANNING, RELATED INSTRUCTION AND INTERAGENCY COORDINATION FOR ALL SPECIAL EDUCATION STUDENTS. THE MOVEMENT FROM SCHOOL TO POST-SCHOOL ACTIVITIES IS AN IMPORTANT EVENT IN TERMS OF THE INFORMATION WHICH CAN BE CAPTURED AND ANALYZED. SPECIFICALLY, THE EMPLOYMENT HISTORY OF DISABLED INDIVIDUALS HAS BEEN A CONCERN NOTED IN A NUMBER OF ...

Not Available The development of a high performance laser with low relative intensity noise (RIN) for RF photonics application is proposed. The laser has a modulation doped multi-quantum well active region and is fabricated on a p-type substrate. The former is needed for low RIN because the modulation doped multi-quantum well design increases the resonance frequency, and the latter is needed fo ...
