KVH INDUSTRIES PROPOSES TO DEMONSTRATE THE FEASIBILITY OF DEVELOPING A MINIATURIZED ORTHOGONAL MAGNETIC SENSOR ASSEMBLY WHOSE VOLUMETRIC DIMENSION, INCLUDING SHIELD, WILL NOT EXCEED 10 CM(3). THE UNIT HAS AS OBJECTIVES A SENSITIVITY OF 1 NANOTESLA WHILE OPERATING AT FLUX DENSITIES OF UP TO 20 OERSTED. FURTHERMORE, THE SYSTEM DRIFT AT ROOM TEMPERATURE IS NOT TO EXCEED 1 NANOTESLA WITHIN A 60 MINUTE ...

WE PROPOSE A NEW LASER MACHINING TECHNIQUE USING NONLINEAR SELFFOCUSING MEDIA SUCH AS CARBON DISULFIDE AND NITROBENZENE. THE TECHNIQUE USES THE CATASTROPIC SELF-FOCUSING SOLUTIONS TO THE NONLINEAR WAVE EQUATION TO PRODUCE INTENSE NON-DIFFRACTING OPTICAL FILAMENTS IDEALLY SUITED FOR PRODUCING SMALL HOLES. THE "LIQUID OPTICS" OFFERS SEVERAL ADVANTAGES OVER CONVENTIONAL OPTICAL FOCUSING: 1) CONSIDERA ...

THE PROPOSED RESEARCH BUILDS UPON THE CONTRACTOR'S PROPRIETARY NEURAL NETWORK SPACE-TIME MEMORY, THE PARAMETRIC AVALANCHE, TO DETERMINE A SET OF DESIGN CHARACTERISTICS FOR NEUROCOMPUTING ARCHITECTURES THAT WILL EFFECTIVELY SUPPORT REAL TIME UNDERSTANDING OF DYNAMIC IMAGERY. THE APPROACH TO THIS PROBLEM IS TO USE THE PARAMETRIC AVALANCHE TO IMPLEMENT A KALMAN FILTER WHICH IS CAPABLE OF TRACKING AND ...

N/A

ALGORITHMS WILL BE DEVELOPED FOR ENHANCEMENT AND SEGMENTATION OF FLIR IMAGES, WITH A VIEW TOWARD REAL-TIME IMPLEMENTATIONS ON SEQUENCES OF IMAGES ACQUIRED AT VIDEO-FRAME RATES. THE METHODOLOGY PIONEERED BY PERSONNEL ON THIS PROJECT, USING PROBABILISTIC MARKOV RANDOM FIELD MODELS AND COMPUTATIONAL METHODS SUCH AS SIMULATED ANNEALING (STOCHASTIC RELAXATION WITH ANNEALING), WILL BE EXTENDED IN TWO DI ...

COMMON TECHNOLOGY CAN BE APPLIED TO THE DIGITAL SIMULATION OF FLOW OVER AERODYNAMIC CONFIGURATIONS AND TO THE CALCULATION OF RADAR CROSS-SECTION. NUMERICAL SOLUTION OF MAXWELL'S EQUATIONS CAN BE ACHIEVED USING THE SAME GRID, DATA BASE AND NUMERICAL METHOD EMPLOYED IN COMPUTATIONAL FLUID DYNAMICS. APPLICATION OF THESE ELEMENTS FROM CFD TO THE CALCULATION OF RCS OF SIMPLE BODIES IS PROPOSED IN THIS ...

N/A

THE OVERALL OBJECTIVE OF THE PROPOSED RESEARCH IS TO INVESTIGATE THE USE OF THE ELECTRICAL POTENTIAL DROP TECHNIQUE AS AN ACCELERATED TEST METHOD FOR DETERMINING THE STRESS CORROSION CRACKING RESISTANCE OF HY-130 STEEL WELDMENTS UNDER CATHODIC PROTECTION IN NATURAL SEAWATER AT AMBIENT TEMPERATURES. WELDS WILL BE DEPOSITED IN 1-INCH THICK HY-130 STEEL BUTT JOINTS. COMPACT TENSION FRACTURE-MECHANICS ...

WE ASSERT THAT THE PRINCIPAL ROLE OF AN ENGINEER IS TO MAKE DECISIONS ASSOCIATED WITH THE DESIGN OF AN ARTIFACT. WE DEFINE DECISION-BASED DESIGN AS THE PROCESS OF PARTITIONING, PLANNING AND MAKING DECISIONS TO DESIGN AND ARTIFACT THAT MEETS SPECIFIED OBJECTIVES. DECISIONBASED DESIGN IS A NEW TERM COINED TO EMPHASIZE A DIFFERENT PERSPECTIVE FROM WHICH TO DEVELOP METHODS FOR DESIGN. IN THE CONTEXT O ...

THE OBJECTIVE IS TO DEMONSTRATE THE FEASIBILITY OF USING NESTOR'S NEURAL NETWORK LEARNING TECHNOLOGY FOR PATTERN RECOGNITION IN A MULTISENSOR AVIONICS SYSTEM ENVIRONMENT. PATTERN MATCHING VIA PARALLEL SEARCHES IN A MULTISENSOR DATA ENVIRONMENT MUST BE CONTROLLED BY AN APPROPRIATE HIERARCHICAL DECISION LOGIC THROUGH WHICH A SYSTEM CAN LEARN HOW BEST TO USE ITS AVAILABLE DATA FOR ROBUST RECOGNITION. ...
