The Federal Railroad Administration’s (FRA) Automated Track Inspection Program uses optical systems such as cameras or laser-based systems to monitor rail performance throughout the country. These systems are hindered by adverse weather conditions that allow water, dirt and mud to coat their optical components resulting in unwanted maintenance costs. Thus FRA is seeking a low-cost, practical s ...

At present, trains use various dissipative braking systems to slow and stop, and this significant braking energy is ultimately converted to heat and wasted. APEI, Inc. has proposed a hybrid tender which can capture and reuse a significant fraction of this braking energy (at least 50%). The hybrid tender draws power from the rails using a regenerative braking technique rather than by being electr ...

IN CARDIOVASCULAR RESEARCH THERE IS AN URGENT NEED FOR METHODS WHICH WOULD QUANTITATIVELY IDENTIFY REGIONS OF HIGH SHEAR STRESSES IN THE FLOW (HEMOLYTIC FACTOR), REGIONS OF HIGH AND LOW STRESSES AT THE WALL (ATHEROMATIC LESIONS), AND SEPARATED OR REVERSE FLOW REGIONS (THROMBOGENIC FACTORS). A COMPUTER MODEL CAPABLE OF SIMULATING PHYSIOLOGICALLY IMPORTANT FEATURES OF BLOOD FLOW IN VESSELS WOULD BE ...

WIDESPREAD CONTROVERSY CURRENTLY EXISTS REGARDING METHODS USED IN THE IDENTIFICATION AND ASSESSMENT OF GIFTED CHILDREN. RESEARCH INDICATES THAT TEACHER NOMINATIONS, THE MOST WIDELY USED METHOD, FAIL ALMOST 50% OF THE TIME TO IDENTIFY THE TRULY GIFTED.THIS PROPOSAL RECOMMENDS THE DEVELOPMENT OF AN EXPERT COMPUTER SYSTEM THAT INTEGRATES ACHIEVEMENT, APTITUDE, AND PERSONALITY TESTS ALONG WITH OTHER P ...

THIS PROPOSAL DESCRIBES PHASE I OF A THREE-PHASE PROGRAM TO DEVELOP AND COMMERCIALIZE A RESPONSE TESTER (RESTER) TO DETERMINE ALCOHOL-INDUCED IMPAIRMENT OF DRIVING SKILLS. IMPAIRMENT WILL BE ASSESSED USING COGNITIVE FUNCTIONS THAT REQUIRE RESPONSES TO VISUAL DISPLAY. THE DEVICE WILL PAIR CRITICAL FLICKER FREQUENCY (CFF) WITH A SECOND TIME-SHARED TASK AND YIELD A QUANTITATIVE MEASURE OF IMPAIRMENT. ...

THE OBJECTIVE OF THIS PROJECT IS TO DEMONSTRATE THE FEASIBILITY OF EFFICIENTLY PRODUCING BIOCHEMICALS FROM MAMMALIAN FIBROBLASTS BY A NOVEL METHOD OF CONTINUOUS CULTURE WITH IMMOBILIZED CELLS. THE NOVELTY OF THIS METHOD CENTERS ON A UNIQUE CELL CARRIER, WHICH ALLOWS FOR A HIGH DENSITY OF CELL PACKING AND FOR MONTHS OF CONTINUOUS CELL GROWTH AND BIOCHEMICAL PRODUCTION. SUPPORTING THE UNIQUE MATRIX ...
