THE OVERALL OBJECTIVE OF THIS PROGRAM IS TO DEVELOP THE TECHNIQUE AND ASSOCIATED INSTRUMENTATION REQUIRED TO REMOTELY MONITOR THE TEMPERATURE DISTRIBUTION DURING HYPER- THERMIA THERAPY IN AND AROUND DEEP-SEATED MALIGNANT TUMORS. THIS TECHNIQUE IS BASED ON THE ULTRASOUND INTERROGATION OF SEVERAL SMALL, PHASE-CHANGING SENSORS (OR TARGETS) IMPLANTEDAROUND THE TUMOR BEING TREATED. IN PHASE I, CONCEPT ...

FEASIBILITY STUDIES OF TWO APPROACHES FOR SENDING HIGH-SPEED TELEMETRY DATA VIA DIGITAL MICROWAVE SYSTEMS ARE PROPOSED. IN THE FIRST APPROACH, TELEMETRY INPUTS ARE MULTIPLEXED INTO A T2 SIGNAL. AS MANY AS 3 OF THESE INPUTS CAN EACH HAVE RATES UP TO 1.8 MB/S. THE SECOND APPROACH INVOLVES AN INVERSE MULTIPLEXER, WHICH SPLITS AT 1.8 MB/S INPUT BETWEEN TWO T1 STREAMS. IN EITHER APPROACH, THE MULTIPLEX ...

THIS PROGRAM WILL DEVELOP METHODS TO OVERCOME THE LIMITATIONS OF CLASSICAL ELASTIC-PLASTIC FRACTURE MECHANICS ON SPECIMEN SIZE WHEN DEVELOPING RESISTANCE CURVES. THE OBJECTIVE OF THE PROJECT IS ASSESSING THE INTEGRITY OF REACTOR PRESSURE VESSELS (RPVS) BY MAKING MAXIMUM MEANINGFUL USE OF THE INFORMATION OBTAINED FROM SMALL SPECIMENS, WHICH ARE OFTEN THE ONLY AVAILABLE SOURCE, WITHOUT AN UNNECESSAR ...

A CORE BODY TEMPERATURE OF LESS THAN 95F REPRESENTS HYPOTHERMIA. THE ELDERLY, BECAUSE OF DEFECTIVE HEAT CONSERVATION, DECREASED HEAT PRODUCTION, MEDICATIONS, IDIOSYNCRATIC RESPONSES TO ILLNESS, SUSCEPTIBILTY TO DISEASES THAT DISRUPT NEUROENDOCRINE FUNCTION, MALNUTRITION,AND SUB-STANDARD HOUSING ARE AT INCREASED RISK FOR HYPOTHERMIA. AMONG THE ELDERLY, HYPOTHERMIA SUBSTANTIALLY INCREASES MORBIDITY ...

THIS EFFORT WILL DESIGN AND DEMONSTRATE BY A COMPUTER SIMULATION A TYPICAL SPACECRAFT TEMPERATURE-CONTROL SYSTEM SYSTEM THAT USES A NON-AZEOTROPIC, TWO-PHASE FLUID AS THE WORKING MEDIUM. THE INNOVATION LIES IN THE USE OF THE NON-AZEOTROPIC FLUID. EXISTING RESEARCH AND EXISTING DESIGNS ARE BASED ON HAVING CONVENTIONAL, SINGLE-COMPONENT OR AZEOTROPIC FLUIDS AS THE WORKING MEDIUM. NON-AZEOTROPIC FLUI ...

FREDWAL INC. WILL DESIGN AND FABRICATE TWO LIGHTWEIGHT FOLIAGE PENETRATION BATTLEFIELD SURVEILLANCE DEVICES (FOLPEN-BSD) FOR THE UNITED STATES MARINE CORPS. THE SOLID STATE, BATTERY OPERATED RADAR WILL HAVE THE ABILITY TO DETECT A SINGLE-MAN OR VEHICLE MOVING THROUGH 300 METERS OF LIGHT TO HEAVY FOLIAGE AND 1500 METERS IN OPEN TERRAIN. THE RADAR WILL CONSIST OF A RECEIVER-TRANSMITTER UNIT, DIAPLAY ...

N/A

THE PROPOSED EFFORT WILL DESIGN, DEVELOP AND TEST AN INTEGRATED COMPUTER ASSISTED METHODOLOGY FOR SPECIFYING, TESTING AND EVALUATING C3I SYSTEMS THAT USE ARTIFICIAL INTELLEGENCE TECHNIQUES. SPECIFIC SYSTEM REQUIREMENTS WILL BE IDENTIFIED AND ANALYZED THROUGH A SURVEY OF EXISTING AND PLANNED SYSTEMS. REQUIREMENTS DEFINITION AND DOCUMENTATION WILL BE BASED ON CLASSICAL SYSTEMS ENGINEERING APPROACH U ...

THIS PROGRAM WILL INVESTIGATE THE FEASIBILITY OF USING SELECTED SYMMETRICAL AND ASSYMETRICAL RETORTABLE SUBSTRATESFOR CONSTRUTING SQUEEZABLE TUBES TO PACKAGE HIGH TEMPERATURE STERILIZED FOOD PRODUCTS. HEAT SEALABILITY AND RETORTABILITY CHARACTERISTICS OF THE SUBSTRATES WILL BE DETERMINED. PROTOTYPE FOOD TUBES WILL BE CONSTRUCTED AND TESTED.

THE AVAILABILITY OF HIGH SENSITIVITY AND RESOLUTION INFRARED DETECTORS FOR THE ARMY IS CURRENTLY LIMITED BY THE PRODUCTION TECHNIQUESNOW USED FOR CREATING EPITAXIAL LAYERS OF MERCURY - CADMIUM - TELLURIDE. IN PARTICULAR, IT IS IMPORTANT TO REDUCE THE TEMPERATURE AT WHICH THE EPITAXY OCCURS, AND THERE IS DATA THAT THIS CAN BE ACCOMPLISHED THROUGH THE USE OF BROAD-BAND ULTRAVIOLET RADIATION. PHASE I ...
