THE PERFORMANCE OF LARGE-SCALE, LIGHTWEIGHT, SPACE-BASED MANIPULATORS IS CURRENTLY LIMITED BY THE AVAILABLE CONTROL SYSTEM TECHNOLOGIES. TO ACHIEVE HIGH PERFORMANCE WITH A SPACE-BASED MANIPULATOR, A CONTROL SYSTEM IS REQUIRED WHICH DOES NOT UNDERGO PERFORMANCE DEGRADATION DUE TO MANIPULATOR LINK FLEXURE. RESEARCH AND DEVELOPMENT IN THE AREA OF COMPLIANT MANIPULATOR CONTROL HAS BEEN HINDERED BY TWO ...

DENTAL ILLNESSES AND INJURIES OCCURRING IN THE FIELD ARE DIFFICULT TO TREAT WITHOUT A DENTAL CHAIR. WE HAVE DESIGNED A FIELD EXPEDIENT DENTAL CHAIR MADE OF COMPOSITE (PRIMARILY HONEYCOMB AND CARBONGRAPHITE FIBER) MATERIALS. THE CHAIR ALLOWS BOTH STAND-UP AND SIT DOWN DENTISTRY. THE CHAIR WEIGHS LESS THAN TEN LB., FOLDS TO A SMALL VOLUME, IS EASILY CLEANED AND IS RUGGED. ADDITIONALLY, THE DEVICE AL ...

BECAUSE OF THE COMPLEXITY OF GEOMETRY, LOADS AND MATERIAL SYSTEMS OF TURBINE BLADES, THE STRESS AND STRENGTH CHARACTERISTICS CAN NOT BE ACCURATELY PREDICTED BY EXISTING METHODS. THE COMPOSITE TURBINE BLADE STRENGTH CAPABILITIES ARE VERY MUCH DEPENDENT UPON THE CONSTITUENT MATERIAL PROPERTIES, PLY ORIENTATIONS AND STACKING SEQUENCE. THE OBJECTIVE OF THE PROPOSED STUDY IS TO DEVELOP A TECHNIQUE TO P ...

FEASIBILITY AND FUNDAMENTAL OPERATION OF AN INNOVATIVE NONBOILING MINIMUM ENERGY HEAT AND MASS TRANSFER DEVICE WILLBE INVESTIGATED. AN ETHANOL/WATER BINARY SYSTEM WAS SELECTED BECAUSE OF ITS COMMERCIAL IMPORTANCE. THE HEAT ANDMASS TRANSFER DEVICE USES AN INERT CARRIER GAS OPERATING AT ATMOSPHERIC PRESSURE TO EVAPORATE ETHANOL AND WATER AND THEN TO CONDENSE WATER AND ETHANOL IN A MANNER SO AS TO RE ...

THE PURPOSE OF THIS STUDY IS THREEFOLD: PART I WILL LAST APPROXIMATELY THREE MONTHS; THE GOAL OF THIS SEGMENT WILL BE TO DEVELOP ALL COMPONENTS REQUIRED FOR A SELF-MANAGEMENT PROGRAM FOR ALL ASTHMATIC PATIENTS. THIS WILL ENTAIL, IN PART, REFINING AND VIDEOTAPING PORTIONS OF A PROGRAM WITH PROVEN EFFICIENCY, WHEEZERS ANONYMOUS. IN ADDITION, RELIABILITY AND VALIDITY OF PAPER-AND-PENCIL INSTRUMENTS U ...

THE OBJECTIVE IS TO DEVELOP A TOOL FOR DESIGNING VORTEX FLAPS ON ADVANCED FIGHTER AIRCRAFT INCLUDING THE EFFECTS OF VISCOSITY. ANALYTICAL METHODS, INC. PROPOSES TO USE AN UNSTEADY TIME-STEPPING VERSION OF ITS SURFACE SINGULARITY PANEL METHOD, VSAERO, AS A BASIS FOR THIS WORK. THIS WILL GENERATE THE PRELIMINARY VORTEX STRUCTURE (LEADING-EDGE VORTICE, FOREBODY VORTICES, ETC.) FOR THE COMPLETE CONFIG ...

THE FLOW FIELD ABOUT POWERED LIFT VEHICLES CAN BECOME VERY COMPLEX DUE TO HIGH ANGLES OF ATTACK AND LIFTING JETS. IN ADDITION TO MODELING PROPULSION/AIRFRAME INTERACTIONS, THEREFORE, FLOW PREDICTION METHODS MUST TREAT THE PROBLEMS OF SEPARATION AND THE TRANSIENT EFFECTS OF PASSING VORTICAL STRUCTURES INTERACTING WITH THE AIRFRAME. ANALYTICAL METHODS, INC. (AMI) PROPOSES TO EXTEND ITS POWERED LIFT ...

WOOD WAFERBOARD COULD BE UTILIZED FOR SIDING AND OTHER EXTERIOR EXPOSURE APPLICATION IF IT WERE MORE DIMENSIONALLY STABLE WHEN EXPOSED TO CYCLIC HUMIDITY CONDITIONS OR ENVIRONMENTS WHERE THE PRODUCT ABSORBS MOISTURE. ASPEN WAFERBOARD MARKETS COULD BE EXPANDED IF THE THICKNESS SWELLING AND LINEAR EXPANSION UNDER WET CONDITIONS WERE EQUAL TO OR LESS THAN PLYWOOD. A FEASIBILITY STUDY WILL DETERMINE T ...
