THE DEVELOPMENT OF AN ELECTROMAGNETIC COMPRESSION PROJECTILE ACCELERATOR THAT CAN MEET THE REQUIREMENTS FOR APPLICATION AS KINETIC ENERGY WEAPON IS PROPOSED. THE PRINCIPAL VIRTUE OF THE PROPOSED CONCEPT, IN ADDITION TO SIMPLICITY AND HIGH EFFICIENCY TYPICAL OF ELECTROMAGNETIC LAUNCHER CONCEPTS PRESENTLY UNDER DEVELOPMENT IS ITS EXPECTED RELIABILITY DUE TO THE FACT THAT, IN CONTRAST TO RAIL GUNS, C ...

Not Available This proposal describes an innovative, ultrashort pulse laser system offering environmental stability, compactness and extremely high efficiency. This will be achieved by the use of a novel diode-pumped, mode-locked ytterbium fiber laser and fiber pulse stretcher, followed by a diode-pumped Yb:YAG amplifier and compact grating compressor. This system will deliver the >5mJ, subpicose ...

THE OBJECTIVE OF THIS WORK IS TO DEVELOP A TENSOR PRODUCT COMPILER THAT CAN PARSE TENSOR PRODUCT FORMULATIONS INTO WORKING CODE FOR SCALABLE PARALLEL PROCESSORS. THE TENSOR PRODUCT COMPILER WILL USE MATHEMATICAL TRANSFORM RULES TO OPTIMIZE CODE FOR SUCH PARAMETERS AS NUMBER OF PROCESSORS, THE ARCHITECTURE OF THE NODE PROCESSORS, THE RELATIONSHIP BETWEEN LOCAL AND GLOBAL MEMORY, AND LATENCY AND BAN ...

A FUNDAMENTAL PROBLEM IN MACHINE VISION FOR DYNAMIC SCENARIO APPLICATIONS IS THE TRADE-OFF BETWEEN SENSOR FIELD-OF-VIEW (FOV), SENSOR ACUITY, AND THE OVERWHELMING AMOUNT OF SENSOR DATA WHICH MUST BE PROCESSED, LIMITING OVERALL SYSTEM, PERFORMANCE. TYPICALLY, FEATURES TO BE RESOLVED IN A SCENE ARE LOCALIZED WITHIN THE FOV. UNIFORM SAMPLING WITHIN THE FOV IS THUS INAPPROPRIATE; REGIONS WITH LITTLE O ...

HYPRES PROPOSES A PROGRAM TO RESEARCH, DEVELOP, AND DEMONSTRATE FEASIBILITY OF A NEW FAMILY OF HIGH-PERFORMANCE SUPERCONDUCTING A/D CONVERTERS USING THE PRINCIPLES OF COUNTING SINGLE MAGNETIC FLUX QUANTA AND OVERSAMPLING; IT IS CAPABLE OF BOTH WIDE-BANDWIDTH AND HIGH ACCURACY OPERATION BY MAINTAINING UNIQUE BANDWIDTH-ACCURACY TRADEOFF RATIO OF 1.5 EFFECTIVE BITS (INSTEAD OF USUAL 1 BIT) PER FACTOR ...

WHEELCHAIR OCCUPANTS IN SCHOOL BUSES ARE EXTREMELY VULNERABLE TO INJURY IN EVEN MODERATE SPEED CRASHES BECAUSE OF THE OPEN ENVIRNOMENT IN WHICH THEY ARE BEING TRANSPORTED TODAY. IT IS COMMON PRACTICE TO TRANSPORT THIS WHEELCHAIR BOUND POPULATION FACING SIDEWAYS IN VANS AND BUSES. THIS SIDE-FACING ORIENTATION EXPOSES THE WHEELCHAIR OCCUPANT TO ADISPROPORTIONATE AMOUNT OF DANGER IN THE EVENT OF FRON ...

Not Available Borates have an intrinsic band edge below 200 nm, which makes them attractive for optical applications in the deep UV. The birefringence of beta-BaB204 (BBO) is large enough to allow phase matching down to the band edge, so crystal growth and processing innovations that improve transmission and the damage threshold in the UV can have a beneficial effect on harmonic generation. This ...

WITH THE EMERGENCE OF THE COMPUTER AS A BASIC TOOL IN THE WORKPLACE, TYPING IS AN ESSENTIAL VOCATIONAL SKILL. PEOPLE WHO ARE UNABLE TO FULLY UTILIZE STANDARD KEYBOARDS HAVE SIGNIFICANLY LOWER TYPING RATES. ABBREVIATION EXPANSION IS A POWERFUL TECHNIQUE FOR SIGNIFICANTLY INCREASING THIS RATE. CURRENT EXPANDERS RESTRICT THEMSELVES TO FIXED ABBREVIATION SCHEMES TO ACHIEVE ACCEPTABLE PERFORMANCE. THIS ...
