DESCRIPTIONS OF TESTS USED TO MEASURE VARIOUS ASPECTS OF VISION ARE SCATTERED THROUGHOUT THE LITERATURE OF FIELDS SUCH AS MEDICINE, PHYSIOLOGY, PSYCHOLOGY, HUMAN FACTORS ENGINEERING, OPTICS AND OTHERS. WITH STEADY ADVANCES IN THE COMPLEXITY OF MILITARY SYSTEMS (NOTABLY AIRCRAFT), THE NEED FOR A READILY ACCESSIBLE AND THOROUGH SOURCE OF MATERIAL ON VISION TESTS BECOMES IMPERATIVE. DCS PROPOSES TO C ...

DEFENSE SYSTEMS, INC. PROPOSES TO DESIGN, DEVELOP, AND TEST A PROTOTYPE CAUSAL SCHEMA EXPERT SYSTEM DECISION AID FOR TACTICAL PLANNING AND OPTION-GENERATION. THIS PROJECT WILL FOCUS ON WEAPON TARGET PLANNING OPTIONS, A PROBLEM DOMAIN WHERE A NUMBER OF SMART DECISION AIDS ARE AVAILABLE. NONE OF THE AIDS FOCUSES DIRECTLY ON THE EXPERT'S CAUSAL SCHEMA. THIS PROPOSAL ENVISIONS AN EXPERT SYSTEM COMPRIS ...

AT PRESENT IT IS DIFFICULT TO DETERMINE THE AXIAL LOAD IN A BOLTED CONNECTION. TORQUE MEASUREMENTS ARE UNRELIABLLE DUE TO VARIABLE FRICTION COEFFICIENTS AND OTHER MORE ACCURATE METHODS SUCH AS HYDRAULIC TENSIONERS, ULTRASONIC MEASUREMENTS, STRAIN GAUGES, AND X-RAY DIFFRACTION ARE OFTEN IMPRATICAL IN THE FIELD. THE PURPOSE OF THIS PROPOSAL IS TO DEMONSTRATE THAT BOLT AXIAL STRESSES, AND THEREFORE L ...

THIS PROPOSAL DESCRIBES THE APPROACH OFFERED BY MARITIME ASSOCIATES FOR EXECUTION OF A LITERATURE REVIEW AND CRITIQUE OF METHODS FOR ASSESSMENT OF HUMAN PERFORMANCE IN DYNAMIC VEHICLE/OPERATOR SETTINGS. THE REVIEW WILL HELP DETERMINE SUITABILITY OF TESTING AND EXPERI MENTAL METHODS USED FOR THIS PURPOSE. THE APPROACH PROPOSED WILL DRAW UPON HIGHLY RELEVANT EXPERIENCE OF MAI IN THE EXPERIMENT DESIG ...

THIS PROJECT WILL FIRST SPECIFY AND THEN IMPLEMENT AN EXPERT SYSTEM TO AID IN THE PLANNING OF OPTIMAL MESSAGE ROUTES IN A LARGE (400 NODE), DYNAMIC TACTICAL NETWORK. WHEREAS CONVENTIONAL NETWORK OPTIMAL ROUTES ARE BASED UPON DELAY MINIMIZATIONS, THE APPROACH HERE WILL BE TO MAXIMIZE THE PROBABILITY OFSUCCESSFUL DELIVERY. THIS OPTIMIZATION WILL REQUIRE ASSESSMENT OF THE RELIABILITY OF EACH LINK AND ...

THERE ARE FIVE MAJOR THEORIES* OF RELEVANCE TO DEVELOPMENT OF A "CONSENSUS THEORY" FOR HANDLING EVIDENCE IN EXPERT SYSTEMS. SINCE THEY HAVE EVOLVED FROM VERY DIFFERENT FIELDS, THEY DO NOT HAVE IDENTICAL ASSUMPTIONS NOR DO THEY SHARE A COMMON NOTATION, TERMINOLOGY, OR SEMANTICS. THE PROPOSED EFFORT SEEKS TO ELUCIDATE THE PRACTICAL IMPACT OF THESE THEORETICAL APPROACHES FOR BUILDERS OF EXPERT SYSTEM ...

Satellite Communication (SATCOM) is a necessity for teams (military or commercial) that are deployed away from their parent organizations. Unfortunately they may not have sufficient power supply/battery capability. By combining a SATCOM Antenna and Solar Cell Array protable, lightweight, and self-sufficient SATCOM Radio will increase the teams efficiency. Astron's experience in the design of UHF S ...

Misacylated transfer RNA's bearing unusual amino acids will be prepared on a preparative scale and employed in in vitro protein biosynthesizing systems to produce polypeptides containing one or more modified amino acids at predetermined positions. The specific goals of the project include (i) determination of the feasibility of preparing misacylated tRNA's on a preparative scale, (ii) assessment o ...

Decision Science Associates, Inc. (DSA) proposes to design and prototype an automated decision aid for the assessment of pre-flight risk by Army rotorcraft pilots. This aid will support the rapid assessment of risk based on readily available information. Phase I consists of 4 tasks. In Task 1 we will identify sources of information and determine the critical predictive factors and the types of dat ...
