The Defense Threat Reduction Agency, DTRA, currently uses technologies capable of detecting IEDs using airborne sensors that are demonstrated as reliable. These systems are only used for detection purposes and are not capable of neutralizing the IED. Due to IEDs being located in remote, dangerous, and hostile locations, there is high casualty risk for personnel to manually neutralize the target by ...

This is a proposal to develop a unique, Ultrashort Pulsed Off-axis Digital Holography (USPODH) system, enabling the high frequency imaging of detailed 3D structures within aerosol fields under harsh thermodynamic conditions and high optical depths where ordinary imaging is essentially useless. Many powerful imaging methods have failed to provide this capability because noise from multiple scatteri ...

In this project, we propose to identify and examine solution growth approaches for engineering perovskite single crystal for gamma spectrometry in a hand-held sensor format. We will demonstrate that the solution growth approach is able to produce perovskite single crystal in sufficient volume and quality to yield a detector crystal whose utilization presents no inherent environmental, health, or s ...

THE GUIDANCE AND SURVEILLLANCE ACCURACIES OF ADVANCED AIR FORCE REENTRY SYSTEMS DEPEND ON ANTENNA WINDOW SHAPE CHANGE (OR ABLATION) AT THE TIME OF THE GUIDANCE UPDATE OR SURVEILLANCE FUNCTION. GUIDANCE UPDATE AND SURVEILLANCE OCCUR IN ALTITUDE REGIMES WHERE PRECURSOR DUST FIELDS CAN EXIST. DUST EROSION OF THE WINDOW WILL CAUSE BORESIGHT ERRORS AND SUBSEQUENT SYSTEM INACCURACIES. THE PURPOSE OF THE ...

THE OBJECTIVES OF THIS WORK ARE TO ESTABLISH THE DESIGN REQUIREMENTS, TECHNICAL FEASIBILITY A BASIC DESIGN, AND A COST DATA BASE FOR DESIGNING AND CONSTRUCTING A LOW COST BUT ADEQUATE CAPABILITY FOR CALIBRATING PRESSURE INSTRUMENTATION USED FOR MEASURING DUSTY BLAST FLOW. IN PARTICULAR SUCH A CALIBRATION FACILITY WOULD BE CAPABLE OF CALIBRATING SINGLE AND MULTIPLE SNOB/GREG PROBES AT THE FLOW SPEE ...

AN ALPHA/BETA RADIATION DETECTOR SUITABLE FOR USE IN THE INSTRUMENT CHANNEL OF A FIBEROPTIC ENDOSCOPE WILL BE WILL BE DEVELOPED TO PROVIDE IN-VIVO IN-SITU BIOASSAY MEASUREMENTS LEADING TO COMPUTER-ASSISTED ESTIMATES OF IN- TERNAL DOSE AND DISTRIBUTION IN THE RESPIRATORY AND GASTRO- INTESTINAL TRACTS. DURING PHASE I OF THE PROGRAM, ALPHA AND BETA PARTICLE SENSITIVE SCINTILLATING PLASTIC FIBERS WILL ...

THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO BUILD A USER-FRIENDLY, PERSONAL COMPUTER BASED WORKSTATION FOR PERFORMING TRAC-BWR ANALYSIS. THE SOFTWARE WILL ALLOW A USER TO READ-IN DATA FROM EXISTING TRAC-BWR INPUT DECKS (ASCII), DRAW NODALIZATION DIAGRAM, MODIFY INPUT, AUTOMATICALLY RENODALIZE THE VESSEL, CHAN AND PIPE COMPONENTS, GENERATE INPUT DECK, SUBMIT JOB, BRING BACK PLOTDATA, DISPLAY RESUL ...

THE PROBLEM OF AERODYNAMIC ENTRAINMENT OF PARTICULATE FROM FRANGIBLE MATERIALS HAS CONSIDERABLE GEOPHYSICAL, TECHNOLOGICAL, AND MILITARY SIGNIFICANCE. PROBLEMS SUCH AS SOIL EROSION, TERRESTRIAL AND PLANETARY DUST STORMS, COAL MINE SAFETY, JET OR DOWNWASH IMPINGEMENT, CHEMICAL PROCESS TECHNOLOGIES AND EXPLOSION GENERATED DUSTY BOUNDARY LAYERS ARE DEPENDENT ON THE PARTICLE SCOURING MECHANISM. THE EF ...

A RESEARCH PROGRAM IS PROPOSED FOR THE DEVELOPMENT OF A VALIDATED METHODOLOGY FOR PREDICTING THE EX-VESSEL BUOYANCY-DRIVEN FLOWS IN THE HOT LEG AND STEAM GENERATOR OF A WESTINGHOUSE PLANT, AND IN THE CANDY CANE HOT LEG OF A B&W PLANT. THE PROPOSED PHASE I WORK PLAN CONSISTS OF (A) REVIEWING AVAILABLE WESTINGHOUSE EXPERIMENTAL DATA AND SIMULATING THE EXPERIMENTAL CONFIGURATION, (B) VALIDATING THE M ...

RECENT TESTS AT IRT CORPORATION THAT WERE PERFORMED ON ADVANCED SCHOTTKEY LOGIC DEVICES HAVE PRODUCED SOME ANOMALOUS RESULTS. DURING ROUTINE LATCHUP TESTS, LATCHUP WAS OBSERVED IN SOME OF THE DEVICES WHEN TESTED AT ROOM TEMPERATURE. HOWEVER, WHEN THE TEMPERATURE OF THE TEST WAS ELEVATED, LATCHUP DID NOT OCCUR IN SOME OF THE DEVICES WHICH HAD LATCHED AT ROOM TEMPERATURE. THIS RESULT IS CONTRARY TO ...
