Ganuna (7)-ray lenses are an advanced technology currently under development at Argonne National Laboratory for arms control application. The purpose of this proposal is to address whether y-ray lens technology can enable an improved system for imaging radioactive isotopes in patients. In nuclear medicine, it is often desirable to generate a y-ray image that shows the exact areas where an emitting ...

Relational Geometric Synthese (RGS) is a new object-oriented paradigm for 3-D geometric design. In RGS-based design, many qualitative and quantitative relationships between geometric objects are captured in a way that permits automatic update, preserving these relationships, following changes in underlying objects. Other advantages include support of a wide variety of curve and surface types; avoi ...

1We are proposing a computerized tomographic (CT) dimensional measurement system that will remedy two of the major problems experienced by current methods: the distortions caused by CT artifacts, and the blurring caused by the system point - spread function (PSF). The distortions resulting from data nonlinearity will be corrected by a calibration process acting upon the x-ray data. The blurring er ...

We propose a method of generating x-rays that will combine high instantaneous output of rotating-anode x-ray tubes with continuous cooling rates as great or greater than fixed-anode tubes. This combination can be achieved in a mechanically simple way, and will reduce spot wobble without vacuum seals, vacuum bearings, deflecting field, or conventional cathodes, by either thermionic or photoemission ...

We propose to develop a general purpose computer code for calculating the scattering from antennas on an aircraft, which is described by a CAD file. The scattering contribution will include both the passive structure mode and active irradiation mode, calculcated by a hybrid of a high-frequency ray technique and a rigorous finite element technique. The proposed code will be made compatible with the ...

U.S. ARMY CECOM HAS IDENTIFIED THE NEED TO DEVELOP AND DEMONSTRATE IMPROVED TRANSPORT TECHNOLOGIES FOR MULTIMEDIA C3 COMMUNICATION SYSTEMS. BENEFITS TO BE OBTAINED INCLUDE ENHANCED SECURITY AND ANTI-JAM SURVIVABILITY, HIGH DATA FLOW EFFICIENCY AND GREATER USE OF WIRELESS TO REPLACE HARD CABLED NETWORKS. THE PROPOSED PROGRAM BRINGS TOGETHER UNIQUE CAPABILITY AND DOD COMMUNICATIONS SYSTEMS EXPERIENC ...

RESEARCH WILL BE CONDUCTED BY HICHEM CORPORATION, TO DEVELOP A NEW TECHNOLOGY FOR PYROLYSIS OF SCRAP TIRES. DISPOSAL OF USED TIRES IS A BIG PROBLEM IN THE WORLD, ESPECIALLY USA, SINCE MORE THAN 2.5 MILLION TIRES ARE DISCARDED EACH YEAR. MOST OF THESE TIRES ARE DISPOSED IN LANDFILLS. PYROLYSIS OF SCRAP TIRES HELPS TO RECOVER AND REUSE MOST OF THE VALUABLE CHEMICAL AVAILABLE IN TIRES. PYROLYSIS OF S ...

THIS PROPOSAL DEFINES A PROGRAM FOR THE DEVELOPMENT OF ADVANCED CRYOGENIC HEAT PIPES. SEVERAL DESIGNS WILL BE EVALUATED AND ULTIMATELY DEVELOPED WHICH WILL OFFER MAXIMUM TRANSMUM TRANSPORT WITH CRYOGENIC FLUIDS WITH A GIVEN ENVELOPED. APPLICATION ISSUES SUCH AS DIODE OPERATION AS WELL AS FLEXIBLE AND ROTATING JOINTS TO PERMIT RADIATOR DEPLOYMENT OR SENSOR POINTING WILL BE ADDRESSED. OPTIMIZED HEAT ...

A CRYOGENIC HEAT PIPE THERMAL SWITCH (CHPTS) IS PROPOSED FOR DEVELOPMENT FOR APPLICATIONS TO 60 K OR LESS. A CHPTS OFFERS THE ADVANTAGES OF HIGH "ON" CONDUCTANCE, LOW "OFF" CONDUCTANCE, COMPACT SIXE, HEAT PIPE TRANSPORT, AND LOW PARASITIC HEAT INPUTS IN BOTH THE "ON" AND "OFF" MODES. THE METHOD PROPOSED INCORPORATES GAS CONTROLLED VARIABLE CONDUCTANCE HEAT PIPE TECHNOLOGY WITH A TEMPERATURE CONTRO ...
