THE FEASIBILITY OF SHOCK OR SHEAR SENSITIVE COLLOIDAL SEPARATION BY FLOW THROUGH THIN CHANNELS IS EXAMINED. COLLOIDAL SIZE PARTICLES HAVE LOW DIFFUSIVITIES AND MAY BE FRACTIONATED BY FLOW. IN SEPARATION BY FLOW A SAMPLE IN A CARRIER IS INJECTED INTO A COLUMN WITH BOUNDARY LAYER VELOCITY GRADIENTS DEVELOPING, CAUSING PARTICLES TO EMERGE FROM THE COLUMN ACCORDING TO SIZE. THIS METHODS ADVANTAGES IS ...

IN THE PHASE I OF THE RETAIL INVENTORY MANAGEMENT ADVISORY NETWORK DEVELOPMENT (RIMAND) EFFORT A LIMNITED PROTOTYPE OF THE ADVISORY NETWORK WILL BE DEVELOPED. A SMALL AREA OF RETAIL INVENTORY MANAGEMENT RESPONSIBILITY WILL BE EXAMINED, AND THE ASSOCIATED POLICIES AND PROCEDURES WILL BE CODIFIED IN AN EXPERT SYSTEM IMPLEMENTED ON A PROGRAMMABLE WORKSTATION. A DEMONSTRATION OF THE NETWORK ACCESS FAC ...

WE PROPOSE TO DETERMINE THE FEASIBILITY OF DEVELOPING EXTREMELY FAST COMPUTER SWITCHING COMPONENTS BASED ON A METHOD OF USING LIGHT TO MODULATE ATOMIC TRANSITIONS. THE TECHNIQUE OF USING LIGHT TO MODULATE ATOMIC TRANSITIONS IS NOT NEW. LASERS OPERATE BY OPTICALLY STIMULATING A PREPARED SYSTEM TO UNDERGO ATOMIC TRANSITIONS. THE UNDERLYING PRINCIPLES OF ATOMIC PHYSICS HAVE BEEN UNDERSTOOD SINCE THE ...

THIS PROJECT WILL DEVELOP A MANUAL FOR PROGRAM MANAGERS TO IMPROVE IMPLEMENTATION OF DOD INSTRUCTION 4245.4, "ACQUISITION OF NUCLEAR SURVIVABLE SYSTEMS." THIS INSTRUCTION PROVIDES GENERAL MANAGEMENT AND DOCUMENTATION GUIDANCE FOR NUCLEAR SURVIVABILITY AND HARDNESS ACTICITIES. THE MANUAL WILL PROVIDE PROGRAM MANAGERS WITH INFORMATION ON THE PROGRAMMATIC ASPECTS OF DOD 4245.4, MAKING REFERENCE TO SO ...

IT IS PROPOSED TO DEVELOP A SET OF ADVANCED ADAPTIVE NULLING ALGORITHMS TO ENABLE SENSOR ARRAYS TO OPERATE EFFECTIVELY IN A RAPIDLY CHANGING ELECTROMAGNETIC ENVIRONMENT CHARACTERIZED BY SPREAD-SPECTRUM SIGNALS AND SOPHISTICATED JAMMERS. AS ENVISIONED THE ADVANCED ADAPTIVE NULLING ALGORITHM WILL CONSIST OF TWO ELEMENTS: (1) A QUICK REACTION CAPABILITY (QRC) THAT ENABLES THE ARRAY TO RESPOND RAPIDLY ...

THE OVERALL GOAL OF THE RESEARCH IS TO DEVELOP A VALID, USEFUL INSTRUMENT FOR SCREENING ADOLESCENTS WITH DRINKING PROBLEMS. IT IS ESTIMATED THAT 10% TO 20% OF ADOLESCENTS IN AMERICA SUFFER FROM DRINKING PROBLEMS, AND THERE CURRENTLY EXISTS NO RELIABLE AND VALID SCREENING INSTRUMENT THAT WILL ENABLE PRACTITIONERS TO PROVIDE THEM WITH APPROPRIATE INTERVENTION AND TREATMENT SERVICES. PHASE I WILL INC ...

AN IMPROVED GATED VIDEO CAMERA WILL BE DEVELOPED AND RUGGEDIZED TO PERMIT THE ACQUISITION OF WEAPON POINTING ERRORS ON STABILIZED VEHICLE MOUNTED WEAPON SYSTEMS IN A HIGH SHOCK AND VIBRATION FIELD ENVIRONMENT. IMPROVEMENTS OVER EXISTING GATED CAMERAS WILL BE IN THE AREAS OF PHYSICAL SIZE AND WEIGHT, SENSITIVITY, RESOLUTION, LINEARITY, AND DYNAMIC RANGE. VIDEO SIGNAL INTERFACING WILL BE COMPATABLE ...

ALTHOUGH GOVERNMENT AND PRIVATE INSTITUTIONS HAVE EXPENDED VAST RESOURCES TO COMPILE DATA ON FOOD COMPOSITION, CONTAMINANTS IN WATER AND FOODS, AND CONSUMPTION, SUCH DATA ARE GENERALLY UNATTAINABLE OR INCOMPLETELY UTILIZED BY SCIENTISTS, REGULATORS, AND BUSINESSES NEEDING SOPHISTICATEDINSIGHT INTO THE NATURE AND CONSEQUENCES OF THE STRUCTURAL COMPONENTS AND CHEMICAL CONTAMINANTS IN OUR DIET. THE D ...

A PHASE I PROPOSAL TO DEVELOP A FUNCTIONAL SPECIFICATION ANDOPERATIONAL PROTOTYPE OF A TECHNOLOGICALLY SOPHISTICATED WRITING TOOL FOR VISUALLY IMPAIRED STUDENTS. PROVISIONALLY ENTITLED "COAUTHOR", THE PROGRAM WILL BE IMPLEMENTED AS AN ENHANCED-FUNCTION WORD PROCESSOR SUPPORTED BY AN ASSEMBLAGE OF RELATED INTEGRAL UTILITIES THAT INCLUDE: A FUNCTION FOR CONVERTING TEXT AND SYSTEM MESSAGES TO SYNTHET ...
