Currently, there are over 10,000 MRI scanners used in the US alone. US citizens today are mobile and many times medical treatments may require MRI scans from several different facilities. Images from MRI scanners can also drift over time. There is a tremendous need for all medical imaging scanners to be on the same level. Sigma-K will develop the commercialization of the ISMRM/NIST MRI Calibration ...

MSI"s Phase I efforts demonstrated a concept for massively distributed social problem-solving that we propose to develop into a full-featured framework enabling communities to form solutions to complex, multi-factor problems. The ePluribus Solver is motivated by the"wisdom of the crowds"philosophy that proposes that a solution can emerge from a large, diverse group that is superior to a solution f ...

Human Social Cultural Behavioral (HSCB) modeling has been described as"the most difficult task humans have yet undertaken"(Pew and Mavor, 1998). Central to this effort is a fundamental understanding of human behavior, but this understanding is currently based on observations that are not only qualitative, but also biased. Neuroimaging modalities such as functional magnetic resonance imaging (fMRI) ...

CURRENT FRAME BUFFER TECHNOLOGY IS NOT OPTIMIZED FOR USE WITH GENERAL PURPOSE PROCESSORS. THIS PROPOSAL IS FOR A PROGRAM TO DEVELOP A BREADBOARD FRAME BUFFER WHICH IS EFFICIENTLY ACCESSED BY SUCH PROCESSORS. THE FRAME BUFFER IS BASED ON THE VME BUS AND IS SCALABLE TO LARGE AMOUNTS OF IMAGE MEMORY AND VERY FAST IMAGE ACQUISITION RATES. ALL IMAGE DATA IS RANDOMLY ACCESSIBLE AT HIGH SPEED. ANTICIPATE ...

FOUR BEARINGLESS, SHAFT MOUNTED GENERATORS WITH OUTPUTS OF 10, 100, 500 AND 1000 WATTS OF 12-15 V DC WILL BE DESIGNED AND COMPUTER MODELED TO BE DRIVEN BY MODEL AIRPLANE SIZE RECIPROCATING ENGINES. DESIGN COMBINATIONS OF IRONLESS DISK AND IRON LAMINATION CYLINDRICAL GENERATORS USING RARE EARTH AND CERAMIC PERMANENT MAGNETS WILL BE MODELED FOR RELIABILITY WITH THE LOWEST WEIGHT AT THE HIGHEST EFFIC ...

MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

A TECHNIQUE FOR OBTAINING TRUSTWORTHY COMPILATION BASED ON A COMPILATION CHECKER (SIMILAR TO A PROOF CHECKER) IS PROPOSED. THE TRANSFORMATIONS USED IN A COMPILER WILL BE FORMALLY SPECIFIED AND VERIFIED USING INTERPRETER EQUIVALENCE METHODS. THE COMPILER WILL BE INSTRUMENTED TO PRODUCE A TRACE OF THE TRANSFORMATIONS APPLIED IN THE COMPILATION OF A GIVEN PROGRAM. THE COMPILATION CHECKER WILL VALIDAT ...

LOW OBSERVABLE (LO) OPERATIONS ARE THWARTED WHEN CONTRAILS ARE FORMED. IT IS ESSENTIAL THAT MEANS BE SOUGHT TO AUTOMATICALLY DETECT AND ONCE DETECTED, ELIMINATE THIS VISUAL SIGNATURE SO THAT THE OPERATIONAL ADVANTAGE OF REDUCED RADAR CROSS SECTION AND INFRA-RED SIGNATURES CAN BE FULLY EXPLOITED FOR OBTAINING COMBAT ADVANTAGE. A PASSIVE, EXHAUST SYSTEM DESIGN IS PROPOSED WHICH PROVIDES EXTREMELY HI ...

RESONANT ULTRASOUND INSPECTION CAN RAPIDLY FIND CRACKS FLAWS AND TOLERANCE ERRORS IN SOLID STRUCTURES. IN METALLIC BEARINGS, WE HAVE MEASURED SPHERICITY TO 50PPM (.0002 MM IN .5 CM BEARING) AND, IN ADDITION, WERE ABLE TO DETERMINE THE PRESENCE OF FLAWS WITH THE SAME SENSITIVITY. RECENT TESTS BY LANL, USING A JOINT LANL/QUATRO PATENT DISCLOSURE, HAVE INCREASED THIS SENSITIVITY SEVERALFOLD, HOWEVER, ...
