THE JOINED-WING AIRPLANE IS A NEW TYPE OF AIRCRAFT CONFIGURATION EMPLOYING TWO SETS OF WINGS RIGIDLY CONNECTED TOGETHER TO FORM A TRIANGULATED SELF-BRACING STRUCTURE. FINITE-ELEMENT STRUCTURAL ANALYSES AND WIND-TUNNEL TESTS HAVE SHOWN THAT, COMPARED TO CANTILEVER-WING AIRCRAFT, JOINED WING AIRCRAFT ARE LIGHTER, STIFFER, AND HAVE HIGHER SPAN-EFFICIENCY FACTORS, GIVING LOWER INDUCED DRAG. THE JOINED ...

THE FOLLOWING PROPOSAL IS FOR EXPLORATORY RESEARCH INTO A PLANNING APPROACH, CALLED BEHAVIORAL PLANNING, WHICH EMPHASIZES ROBUST AGENT PERFORMANCE IN UNRESTRICTED ENVIRONMENTS, WHILE POTENTIALLY SACRIFICING GUARANTEED ABILITY TO ACCOMPLISH GOALS. THIS WORK IS MEANT AS AN ALTERNATIVE TO PLANNERS OF THE LOGIC-INTENSIVE VARIETY WHICHPRODUCE PROVABLY CORRECT ACTION SEQUENCES, BUT HAVE BEEN DEVELOPED E ...

THE OPERATIONS MANAGEMENT SYSTEM FOR THE SPACE STATION POSSESSES MANY OF THE ATTRIBUTES OF A ROBOT; IT HAS SENSORS,EFFECTORS (WHICH ISSUE COMMANDS TO STATION SUBSYSTEMS), AND A PLAN (THE STP) WHICH MUST OPERATE IN A COMPLEX AND UNPREDICTABLE ENVIRONMENT. THE OMS ALSO SHARES MANY OF THE PROBLEMS OF ROBOT SYSTEMS; IT MUST REFINE AND ADAPT PLANS TO CHANGING CIRCUMSTANCES, IDENTIFY REASONABLE RESPONSE ...

A FUNDAMENTAL PROBLEM WITH AUTOMATING NAP-OF-THE-EARTH HELICOPTER FLIGHT IS THE EXTRACTION AND REPRESENTATION OF INFORMATION ABOUT THE RAPIDLY CHANGING RELATIONSHIP BETWEEN THE HELICOPTER AND THE SURROUNDING ENVIRONMENT. WE TREAT MOTION ANALYSIS AS INVOLVING SEVERAL EXPLICIT LEVELS OF PROCESSING AND REPRESENTATION. THE DIFFERENT LEVELS CONSTRAIN AND DIRECT EACH OTHER SIGNIFICANTLY FOR DETERMINING ...

RESEARCH AND DEVELOPMENT OF ADVANCED LASER-BASED DIAGNOSTICSFOR THE DETERMINATION OF DROP SIZE SPECTRA AND LIQUID WATER CONTENT (LWC) FOR AIRCRAFT ICING RESEARCH IS PROPOSED. THISEFFORT WILL LEAD TO THE DEVELOPMENT OF INSTRUMENTS THAT ARE SUITABLE FOR OBTAINING RELIABLE DATA IN LARGE SCALE ICING RESEARCH TUNNELS AND AIRBORNE CLOUD MEASUREMENTS. SUCH DATAARE FUNDAMENTALS TO THE RESEARCH IN AIRCRAFT ...

AMONG THE MANY SOFTWARE ENGINEERING CONCEPTS DEVELOPED TO INCREASE PROGRAMMER PRODUCTIVITY, ONE OF THE MOST PROMISING AND MOST SOUGHT AFTER IS REUSE OF EXISTING, PROVEN SOFTWARE. A GENERAL PROGRAM, ALSO REFERRED TO AS THE "ARCHETYPED SOURCE", CAN BE ADAPTED TO A BROAD SPECTRUM OF SPECIFIC SITUATIONS. AN EXAMPLE IS A PROGRAM FOR MULTI-SENSOR INTEGRATION, WHICH CAN BE INSTANTIATED FOR VARIOUS COMBIN ...

A MINIATURE, LOW-POWER, GAAS MONOLITHIC GHZ WAVEFORM DIGITIZER IS PROPOSED FOR ANALYZINGSPACE-BASE LASER ALTIMETER PULSE-SPREADING EFFECT. IT CONSISTS OF A GHZ GAASSAMPLE-AND-HOLD AND A 6-BIT MONOLITHIC GAAS FLASH A/D CONVERTER USING THE ENHANCEMENT/DEPLETION (E/D) TECHNOLOGY AND LATCHING COMPARATORS. THE ADVANTAGES OF THE APPROACH ARE: (1) THE USE OF A FRONT-END SAMPLE-AND-HOLD ELIMINATES THE CLO ...
