A FEASIBILITY STUDY ON THE DEVELOPMENT OF A STOICHIOMETRIC DIESEL ENGINE IS PROPOSED USING THE THERMAL IGNITION COMBUSTION CHAMBER. THE ADIABATIC DIESEL ENGINE WITHOUT WATER OR AIR COOLING ALLOWS THE THERMAL IGNITION CHAMBER TO STORE HEAT DURING COMBUSTION AND RELEASE THE ENERGY FOR IGNITION IN THE FOLLOWING CYCLE. INJECTION OF FUEL ON TO 1800-2000 DEG. F WALL TEMPERATURE WILL PREPARE THE FUEL FOR ...

THIS PROPOSAL IS TO DEMONSTRATE FEASIBILITY OF INSERTION OF SIALIC ACID MOLECULES INTO MEMBRANES OF LIPOSOMES CARRYING HEMOGLOBIN. THE LIPOSOMES MAY BE PROVIDED BY NAVY CONTRACTORS OR PREPARED BY OFFEROR ACCORDING TO CONTRACTORS' SPECIFICATIONS FOR FOMULATION. THE ADDED SIALIC ACID WILL PROTECT THE LIPOSOMES FROM CLEARANCE BY THE RETICULOENDOTHELIAL SYSTEM AND THEREBY INCREASE THE RESIDENCY TIME O ...

A NEWLY CONCEIVED SENSOR USES PULSED RF ENERGY CONDUCTED ALONG THE GROUND SURFACE TO IMMEDIATELY DETECT ANY OBJECT OR PERSON CROSSING A SELECTED AREA. THE SENSING ELEMENT IS THE GROUND ITSELF SINCE GROUND CONDUCTIVITY (RESISTANCE -1) CHANGES WHEN COMPRESSED BY THE WEIGHT OF AN OBJECT. USING ADVANCED SIGNAL PROCESSING TECHNIQUES, THE SENSOR TRANSLATES THE CHANGE IN GROUND CONDUCTIVITY INTO A WARNIN ...

AS YET UNIDENTIFIED PHYSICAL MECHANISMS HAVE CAUSED ABRUPT CHANGES IN THE FLIGHT PATHS OF HIGH-SPEED MISSILES WHICH HAVE LARGE LENGTHTO-DIAMETER RATIOS AND ARE RELATIVELY FLEXIBLE. THESE FLIGHT INSTABILITIES ARE PROBABLY CAUSED BY THE NONLINEAR INTERACTION OF MISSILE VIBRATION AND ROTATION, AERODYNAMIC FORCES AND THE MISSILE'S PROPULSION SYSTEM. TO REAP THE BENEFITS OF THE HIGHER AERODYNAMIC EFFIC ...

THE IMPROVEMENT OF SINGLE CRYSTAL DIAMOND TOOLS VIA THE INVESTIGATION OF DESIGN ALTERNATIVES TO EXISTING EDGE TECHNOLOGIES EQUIPMENT TO IMPROVE ROUNDNESS OF TOOL NOSE RADIUS AND DETERMINATION OF OPTIMUM DIAMOND CRYSTAL ORIENTATION, EDGE PREPARATION AND TITANIUM NITRIDE COATINGS TO IMPROVE TOOL EDGE DURABILITY WHEN MACHINING HIGH PHOSPHOROUS ELECTROLESS NICKEL MATERIALS.

A UNIQUE METHODOLOGY FOR SOLID-STATE ELECTRONIC GIMBALLING OF MISSILE SEEKERS IS DESCRIBED. THE APPROACH UTILIZES THE ABILITY OF SOLID-STATE IMAGING SENSOR TO DYNAMICALLY POSITION THE AREA OF INTEREST IN THE SCENE FOR ELECTRONIC STABILIZATION. THE PROPOSED CONCEPT IS BASED UPON THE ADAPTATION OF THE CCD CLOCK SIGNALS TO OUTPUT THE DESIRED IMAGE. PROPER SHIFTING OF THE CCD VERTICAL AND HORIZONTAL R ...

WE PROPOSE TO PRODUCE A PRELIMINARY DESIGN OF A FIFTH-SCALE REMOTE CONTROL HELICOPTER REPRESENTING A BLACK HAWK OR APACHE. THE DESIGN WILL BE PRODUCED SUCH THAT ROTORS CAN BE EASILY CHANGED FOR ROTOR EMPIRICAL RESEARCH OR TESTING. WE WILL USE AS MUCH AS POSSIBLE AVAILABLE HARDWARE AND TECHNIQUES, AND DRAW FROM OUR OWN EXTENSIVE EXPERIENCE WITH US ARMY MICOM FIFTH-SCALE REMOTELY PILOTED HELICOPTER ...

THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP SOFTWARE HAZARD ANALYSIS TECHNIQUES TO BE USED ON EXISTING AND DEVELOPING SYSTEMS. THE TECHNIQUES SHOULD WORK WITH PROGRAM DESIGN LANGUAGES FOR SYSTEMS UNDER DEVELOPMENT AND WITH WRITTEN CODE FOR SYSTEMS ALREADY DEVELOPED. IN BOTH NEW AND DEVELOPED SYSTEMS THE TECHNIQUES SHOULD ADDRESS THE INTERFACE BETWEEN HARDWARE AND SOFTWARE WHERE EXPERIENCE HAS SHO ...
