THIS PROJECT OUTLINES A RELIABILITY AND MAINTAINABILITY KNOWLEDGE BASE AND THE HYPERTEXT INTERFACE REQUIRED TO TRANSPORT THIS DATA INTO COMPUTER-AIDED DESIGN (CAD) ENVIRONMENTS. THE PRIMARY FOCUS OF THE PROPOSAL IS THE DEVELOPMENT OF THE FOUNDATION FOR AN ENGINEERING RELIABILITY AND MAINTAINABILITY INFORMATION PRESENTATION SYSTEM TO SUPPORT ELECTRONIC CIRCUIT AND SYSTEMS DESIGN ENGINEERS IN A CAD ...

AN INTEGRATED GROUND-WATER/SOIL-GAS MONITORING SYSTEM WILL BE DESIGNED, CONSTRUCTED AND TESTED. THE BASIS OF THE INTEGRATED SYSTEM WILL BE TO PLACE THE VOLATILE ORGANIC CHEMICALS (VOCS) INTO THE SAME SAMPLE FORM, I.E. VOCS IN AN INERT GAS SUCH AS NITROGEN, FOR ANALYSIS. TO ACCOMPLISH THIS A GROUND-WATER SAMPLER WILL BE DESIGNED WHICH WILL COLLECT A GROUND-WATER SAMPLE WITHOUT PURGING THE WELLS. TH ...

THE PROPOSED PROGRAM INCLUDES THE ANALYSES, INVESTIGATIONS, AND EVALUATIONS NECESSARY TO RECOMMEND A DESIGN OF A MINIATURE, LOW-COST, IMPACT HISTORY SENSOR. THE BASIC DESIGN CONSISTS OF AN TRIAXIAL ACCELEROMETER, ANTI-ALIASING FILTERS, ANALOG-TO-DIGITAL CONVERSION, AND DIGITAL SIGNAL PROCESSOR AND MEMORY. A PACKAGING PROTOTYPE SENSOR WILL BE BUILT AND TESTED DURING PHASE I. PHASE II WILL RESULT IN ...

A SOLID STATE SWITCH FOR OPERATION AT CRYOGENIC TEMPERATURE IS BEING DEVELOPED THAT WILL PROVIDE MULTI-MEGAWATT POWER CONDITIONING IN THE RAPIDLY EXPANDING FIELD OF LOW TEMPERATURE ELECTRONICS. SINCE EXISTING CONTROLLED SWITCHES ARE NOT DIRECTLY SUITABLE FOR CRYOGENIC OPERATION, ONLY A FUNDAMENTAL APPROACH CAN DEVELOP STRUCTURES CAPABLE OF LOW LOSS AND RELIABLE OPERATION IN THE TEMPERATURE RANGE B ...

THE OBJECTIVE OF THIS PROPOSAL IS TO IDENTIFY THE ADJUSTMENT OF FLAMES BY ENERGY FIELDS TO CAUSE OR TO INCREASE THE POTENTIAL FOR FIRE EXTINGUISHMENT, AND TO DETERMINE THE ENERGY FIELD WHICH PROVIDES OPTIMAL EFFECTS.

WE PROPOSE TO DEVELOP A SET OF FORMAL ABSTRACT DATA MODEL WHICH WILL CREATE AN OPEN ARCHITECTURE FOR ELECTRONICS COMPPUTER-AIDED DEIGN, EVALUATION, TEST, AND DIAGNOSIS TOOLS. OUR ARCHITECTURE IS MODELED AFTER THE HIGHLY SUCCESFUL OPEN SYSTEM INTEROCNNECTION REFERENCE MODEL WHICH HAS BECOME THE INTERNATIONAL STANDARD FOR COMMUNICATION SYSTEMS. THE OSI MODEL SPECIFIES DATA AND OPERATIONS ONLY AT THE ...

THIS PROPOSAL OUTLINES A SIMPLE YET ACCURATE APPROACH TO MEASURING THE POSITION AND ORIENTATION OF A ROBOT. THE MECHANISM CAN BE USED TO MAKE BOTH STATIC AND DYNAMIC MEASUREMENTS. TWO VERSIONS OF THE DESIGN ARE PROPOSED; THE FIRST VERSION HAVING HIGH ACCURACY OVER A SMALL WORK VOLUME,AND THE SECOND VERSION HAVING LOWER ACCURACY OVER A WORK VOLUME WHICH WOULD ALLOW POSE MEASUREMENT OVER THE ENTIRE ...

THERE IS A CHRONIC NEED FOR LIGHTER YET STRONGER MATERIALS FOR BOTH AMBIENT AND ELEVATED TEMPERATURE APPLICATIONS IN BOTH IAILITARY AND COMMERCIAL SECTORS. ONE REQUIREMENT IS FOR A 9OODEGF ALUMINUM FASTENER COMPATIBLE WITH ALUMINUM AND TITANIUM ALLOYS. MECHANICAL ALLOYING/RAPID SOLIDIFICATION PROCESSING USING INTERMETALLIC AND SPINEL DISPERSIONS HAVE DEMONSTRATED PROMISE FOR INCREASING THE SERVICE ...

THE DISSEMINATION OF TIMELY WEATHER DATA IS BECOMING INCREASINGLY IMPORTANT AS THE POPULATION DENSITY OF THE UNITED STATES INCREASES. AS THE SOLE GOVERNMENT OPERATED RADIO SYSTEM PROVIDING DIRECT WARNINGS TO PRIVATE HOMES, THENOAA WEATHER RADIO (NWR) SYSTEM IS CRITICAL FOR DISSEMINATING NATURAL DISASTER WARNINGS AND THE TIMELY DISSEMINATION OF WEATHER DATA. THE NEED FOR A LOW COST, REAL TIME COVER ...

THREE ASPECTS OF CLIMATE CHANGE INVOLVING VERY HIGH TROPICAL CLOUDS ARE: (1) WHETHER CHANGES IN HIGH CLOUD PARAMETERS LEAD TO POSITIVE OR NEGATIVE FEEDBACK IN CO2 EFFECTS ON CLIMATIC TEMPERATURE CHANGES; (2) DO CHANGES IN THE HEIGHTS OF CLOUD TOPS AND CLOUD AMOUNT, OR CLOUDS WHICH REACH TO THE TROPICAL TROPOPAUSE, AFFECT THE AMOUNT OFWATER VAPOR IN THE LOWER STRATOSPHERE AND INDIRECTLY THE ANTARCT ...
