An approach to object identification and sensor fusion of images is proposed. Preprocessing techniques which perform a useful and computationally efficient transformation on the image will be considered. Once the image has been transformed to a more efficient format, mathematical morphology and neural networks are proposed to address the issues of edge detection, identification, sensor fusion and ...

We will use an innovative neural network algorithm to perdict and control National Aero-Space Plane(NASP) unstarts at the earliest possible moment. Unstarts present a design challenge to hypersonic aircraft. An unstart occurs when the pressure at the aft end of the engine flow path reaches a critical level. This overpressure causes a "choking" of the air flow. The flow tends to spill around the in ...

A low risk, low cost, classical design observation vehicle will be developed for gull launching. The observation vehicle concept is based on a light-weight loitering aircraft, packaged in a "shell" that will enable the aircraft to survive the large acceleration/deceler- ation loads associated with gun launch systems. The shell encasing the observation aircraft and avionics payload is designed to ...

WE PROPOSE TO DEMONSTRATE THE FEASIBILITY OF OPTICAL CHARACTER RECOGNITION (OCR) ON A VLSI NEUROCOMPUTER. THE OCR SYSTEM WILL USE STATE OF THE ART ARTIFICIAL NEURAL NETWORK CLASSIFIERS ONADAPTIVE SOLUTIONS' CNAPS NEUROCOMPUTER CHIPS. THE CNAPS CHIPS OFFERUNPRECEDENTED PERFORMANCE OF ARTIFICIAL NEURAL NETWORKS. THE IMAGE PREPROCESSING OF THE OCR SYSTEM WILL ALSO EXECUTE ON THE CNAPS CHIPS. THE GOAL ...

1We are proposing a computerized tomographic (CT) dimensional measurement system that will remedy two of the major problems experienced by current methods: the distortions caused by CT artifacts, and the blurring caused by the system point - spread function (PSF). The distortions resulting from data nonlinearity will be corrected by a calibration process acting upon the x-ray data. The blurring er ...

Achieving by the year 2010 a significant reduction in part count, cost, size and weight of turbopumps, and improving their reliability and efficiency is accomplished with a series of innovative single stage high head (150,000-200,000 ft) demonstrator pumps which identify critical technological questions, validate design principles and tools, and set the path to realize the IHPRPT Phase II and III ...

A novel signal encoding/decoding method for laser ranging is proposed in response to solicitation AF96-186. Coherent burst ranging utilizes low cost diode lasers to achieve high precision ranging under ambient light conditions while operating at inherently eye-safe power levels. Proprietary signal processing methods to be developed will allow single-shot range resolution of approximately 1 mm at ...

We propose to develop a general purpose computer code for calculating the scattering from antennas on an aircraft, which is described by a CAD file. The scattering contribution will include both the passive structure mode and active irradiation mode, calculcated by a hybrid of a high-frequency ray technique and a rigorous finite element technique. The proposed code will be made compatible with the ...
