Uses of the central visual field, or foveal scotoma, due to accidental exposure to laser light or macular disease can cause serious impairments in visually aided performance. Foveal scotomas also interfere with normal control of eye reations and saccades. Feasibility is tested for using electronic image shifting from scotomatous foveal retina to intact peripheral retina, as a con\mpensation for ce ...

A modified engine cycle based on the early intake valve closing of the Miller or the Adkinson cycle is proposed to meet the needs of the future Military Advanced Diesel Engine. The concpet involves the principle of short, effective compression with long expansion ratio to provide high brake thermal efficiency. This concept is executed by a variable timing rotary valve placed before the standard in ...

Under the performance levels currently achievable for automated target-recognition (ATR) systems, the human operator plays an essential role in screening ATR detections and rejecting false alarms. A critical advantage of human operators over ATR systems is their ability to make use of situation awareness in identifying targets. ALPHATECH proposes a research program to identify the critical paramet ...

Current Army projects, the Intelligent Vehicle Highway System, and the Unmanned Ground Vehicle project require automated signal processing and information processing techniques that distinguish various types of vehicles in real-time. Tasks, such as distinguishing 3-axle trucks from 2-axle trucks or trucks from cars, require image understnding, artificial intelligence, and high performance computin ...

A batteryless and wireless sensor for intrusion detection and assessment of threats which requires no battery, external power or wiring is proposed. These types of sensors derive energy from passing vehicles or persons, and indicate their presence, location, speed, etc., via a self-generated short-range radio signal. These sensors require no maintenance, and can be inconspicuously placed in window ...

IT IS PROPOSED TO DEVELOP AND EVALUATE AN ARCHITECTURE FOR A MULTIELEMENT RADAR RECEIVING ARRAY WHICH PERFORMS DIGITAL BEAM FORMING (DBF) WITHIN THE RECEIVING ARRAY ITSELF, USING EACH ELEMENT AS A NODE OF A SYSTOLIC-LIKE ARRAY PROCESSOR. THE PROCESSOR ASSOCIATED WITH EACH ELEMENT OF THE ARRAY WILL PRODUCE A DIFFERENT SPATIAL BEAM. THIS DISTRIBUTED ARRAY PROCESSING CAPABILITY CAN BE REALIZED BY ADD ...

Subclutter visibility may be achieved using wavelets and wavepacket methodss. Wavelets offer the ability to separate features based on scale. Wavepackets and the best-basis algorithm offer the further advantage of adaptability; bases adapt to the signal to provide optimum signal representation. We propose to develop techniques for separting low altitude, low observable targets from clutter on the ...

THE CHLORINATED ETHENES, VINYL CHLORIDE, VINYLIDINE CHLORIDE, TRICHLOROETHYLENE, AND TETRACHLOROETHYLENE HAVE BEEN DETECTED IN GROUNDWATER THROUGHOUT THE UNITED STATES. VINYL CHLORIDE AND VINYLIDINE CHLORIDE ORIGINATE FROM INDUSTRIAL WASTE DISPOSAL SITES AS WASTE PRODUCTS OF PLASTIC MANUFACTURING AND TRICHLOROETHYLENE IS WIDELY USED AS AN INDUSTRIAL SOLVENT. SINCE THESE COMPOUNDS ARE HIGHLY TOXIC, ...

A PROCESS FOR ADHESIVELY BONDING SELECTED ELASTOMERS IS PROPOSED WHICH CAN SIGNIFICANTLY SIMPLIFY ADHESIVE BONDED MANUFACTURING AND REPAIR PROCEDURES. THE PROPOSED RESEARCH EXPLORES THE FEASIBILITY OF USING NON-HAZARDOUS SURFACE TREATMENTS ON VULCANIZED RUBBER SUBSTRATES WHICH PROVIDE BONDS OF EQUAL OR GREATER STRENGTH THAN THE RUBBER ADHERENDS THEMSELVES. THESE NOVEL SURFACE TREATMENTS SHOULD PRE ...

Billions of gallons of oily wastewaters are generated daily by a variety of industrial sources. A large fraction of these are oil/water emulsions for which current treatment technologies are often costly and ineffective. Although such emulsions can be separated using crossflow filtration technology, conventional crossflow membranes typically are uneconomic for performing such treatment due to st ...
