This Phase II SBIR Project will provide optimization framework and technology for Interoperable Message Passing Interface Technology, and the underlying Message Passing Interface Standard. This effort represents a challenge and Opportunity. With the emergence of cluster computing, there are many opportunities to connect diverse parallel programming Environments based on the MPI programming mo ...

HIGH TEMPERATURE SUPERCONDUCTING (HTSC) FILMS HAVE A LARGE POTENTIAL AS DETECTORS OF ELECTROMAGNETIC RADIATION. TO BE USEFUL FOR TRANSFER STANDARD RADIOMETERS, IT IS NECESSARY THAT THE HTSC FILM QUALITY SHOULD BE VERY HIGH, BOTH FROM THE VIEW POINTS OF STRUCTURE AND SUPERCONDUCTING PROPERTIES. A MAJOR TASK, IN ORDER TO ACHIEVE HIGH SENSITIVITY, FAST RESPONSE, LOW NOISE LEVELS, AND UNIFORM SPECTRAL ...

Recent catastrophic failures of Self Contained Underwater Breathing Apparatus (SCUBA) aluminum gas cylinders and similar air tanks have generated the need for a highly reliable, low cost inspection method to insure the integrity of these tanks. The failures of these tanks have been the result of crack formation in the neck and shoulder area. The cracks originate from the interior wall and can re ...

A NOVEL PHOTOSTIMULABLE PHOSPHOR IMAGING TECHNIQUE IS PROPOSED TO REPLACE BULKY COUNTING SYSTEMS CURRENTLY USED IN NEUTRON DIFFRACTION AND SCATTERING INVESTIGATIONS. THE SIZE AND SHAPE OF THE PROPOSED DETECTOR CAN BE VARIED TO MAKE IT POSSIBLE TO MOVE THE DETECTION SYSTEM CLOSER TO THE SCATTERING SAMPLE, THEREBY INCREASING THE NEUTRONS AVAILABLE FOR DETECTION AND SHRINKING THE SIZE OF THE EXPERIME ...

The storage photostimulable phosphor (SPP) technique has been demonstrated to be sensitive to ionization radiation. It is especially suited for detecting alpha particles since the efficiency is practically 100%. In addition to being able to quantify total ionization deposited in a SPP sensor, it also captures the radiation source distribution information in a digital image which can be readily ana ...

More than 20 years after the advent of balloon angioplasty restenosis remains a major health risk and cost burden. Success in animal trials and treatments in other non-malignant lesions using radiotherapy has established a new branch of medical science, intravascular brachytherapy (IVB) in treating restenosis. In just over 6 years since the first application, there are today more than 500,000 ...

SPECIAL MILITARY NARROW BEAM ACOUSTIC PROJECTORS AND TRANSMISSION TECHNIQUES CAN BE EASILY ADAPTED FOR COMMERCIAL USE TO ENABLE FISHERMEN OR RESEARCHERS TO DETECT,LOCATE, AND QUANTIFY BIOLOGICAL TARGETS WITH VERY HIGH ACCURACY IN SHALLOW WATER. THE PROPOSED EFFORT WILL PROVIDE A METHOD FOR PRODUCING VERY NARROW ACOUSTIC BEAMS WITH VIRTUALLY NO SIDELOBES FROM A SMALL APERTURE PROJECTOR ARRAY. ALSO ...

Critical issues associated with the design of a rugged, compact "real time" sampling system using photoconductive switches as the signal generator and sample will be investigated. The design concept is based upon an optoelectronic equivalent time sampling principle developed by the Principal Investigator. It involves first the phase locking of the temporal waveform to be measured to the optical pu ...
