BY DESIGNING TRANSITION RADIATORS SUCH THAT THERE IS UNIFORM FOIL THICKNESS AND SPACING, THE ANGLE OF EMISSION CAN BE REDUCED AND THE BRIGHTNESS OF THE X-RAY SOURCE INCREASED. UNDER THIS CONTRACT WE WILL CALCULATE THE BRIGHTNESS OF THIS SOURCE AND COMPARE IT TO SYNCHROTRON EMITTERS. IN ADDITION WE WILL INVESTIGATE METHODS FOR REDUCING THE ELECTRON BEAM ENERGY REQUIRED FOR THE PROCESS TO OCCUR. MET ...

WE PROPOSE TO DEVELOP A SIMPLE, PORTABLE, ONE-STEP ASSAY FOR THE DETECTION OF MYCOPLASMA PNEUMONIAE AND INFLUENZA A WHICH CAN BE PERFORMED INDEPENDENT OF A SOPHISTICATED LABORATORY BY UNTRAINED OR SEMI-SKILLED PERSONNEL. THIS SIMPLE, ONE-STEP METHOD IS CALLED AN OPTICAL BIOASSAY (OBA) AND UTILIZES AN INEXPENSIVE LASER AND PHOTODETECTOR TO DETECT AN ANTIGEN-ANTIBODY BINDING EVENT. ANTIBODY IS COVAL ...

SUCCESSFULLY APPLYING MODEL-BASED REASONING TO REAL WORLD VISION PROBLEMS (E.G. AUTOMATIC TARGET RECOGNITION ?ATR?) REQUIRES ACCURATE REPRESENTATION OF COMPLEX RELATIONSHIPS AMONG THINGS IN THE WORLD AND OBSERVABLE IMAGE FEATURES. EVIDENCE ACCRUAL TECHNIQUES MUST BE ABLE TO OPERATE OVER THESE RELATIONSHIPS WITH LITTLE LOSS IN INFORMATION. CURRENT TECHNIQUES SUCH AS BAYESIAN NETWORKS SHOW PROMISE, ...

THE USE OF TRANSLATED OR TRANSDIGITIZED GLOBAL POSITIONING SYSTEM (GPS) SIGNALS IS A PROMISING METHOD FOR DETERMINING THE PRECISE FLIGHT PATH OF AN ARTILLERY SPOTTER ROUND. THE PRIMARY ELEMENTS OF THE GPS ARTILLERY SPOTTER ROUND SYSTEM ARE A GPS TRANSLATOR OR TRANSDIGITIZER IN THE PROJECTILE FUSE AND A TRANSLATED/TRANSDIGITIZED GPS RECEIVER LOCATED AT THE FIRING PLATFORM. THIS SYSTEM WILL PROVIDE ...

HIGH-RESOLUTION COMPUTED TOMOGRAPHY SHOWS SIGNIFICANT PROMISE IN AIDING THE DEVELOPMENT OF ADVANCED COMPOSITE MATERIALS WHICH ARE IMPORTANT IN IMPROVING AIRCRAFT PERFORMANCE. NONDESTRUCTIVE IMAGING OF THE INTERNAL STRUCTURE OF THESE MATERIALS CAN HELP IN IMPROVING PROCESSING QUALITY, IN DEVELOPING PERFORMANCE MODELS, AND IN EVALUATING MANUFACTURED COMPONENTS. CURRENT IMAGING PERFORMANCE COULD BE S ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO DEVELOP TECHNIQUES FOR DETECTING AND QUANTIFYING WEAK OR "KISSING" DEBONDS IN SOLID ROCKET MOTORS. THE PROPOSED TECHNIQUE IS BASED ON X-RAY COMPUTED TOMOGRAPHY.IT IS INNOVATIVE BECAUSE IT DOES NOT REQUIRE THAT ANY GAPS IN THE DEBOND AREA BE RESOLVED. INSTEAD, IT RELIES ON MEASUREMENTS OF THE PROPELLANT DILATATION NEAR THE BONDED INTERFACE TO SHOW WHETHER LO ...

THE PROPOSED DEVICE ALLOWS THE DETECTION, IDENTIFICATION ANDTRACKING OF ALL TYPES OF EXISTING ROADWAY PAVEMENT DELINEATORS. THE INFORMATION WILL PROVIDE LATERAL POSITION SENSING. THE CONCEPT OF ROADWAY LANE POSITIONING IS NOT NEW, BUT RECENT IMPROVEMENTS IN DIODE LASERS AND SOLID STATEDETECTORS PROVIDE THE MEANS TO FINALLY IMPLEMENT A WORKABLE SENSOR. THE PROPOSED OPTICAL SENSOR WILL BE COMPACT, I ...
