1 Stevens, KennethAutomatic synthesis of fast, compact self-timed controlAn automated synthesis tool, called the Most Excellent Asynchronous Tool, or MEAT is presented. This tool has been used to specify and synthesize self-timed circuits for a fully self-timed 300,000 transistor communication co-processor. The Specification is done with stylized state diagrams. This is ...1992
2 Normann, Richard A.; Johansson,Torbjorn; Abbasi, Masoud; Huber, Robert J.Three-dimensional architecture for a parallel processing photosensing arrayA three-dimensional architecture for a photosensing array has been developed. This silicon based architecture consists of a 10 x 10 array of photosensors with 80 microns diameter, through chip interconnects to the back side of a 500 microns thick silicon wafer. Each photosensor consists of a 300 x 3...Retina; Optics; Silicon; Photosensing1992

Theory of the random cell isodisplacement model; Secular equation developed; Results and discussion.Lattice dynamics; Quaternary alloys1992
4 Mathews, V. JohnAn efficient algorithm for joint estimation of differential time delays and frequency offsetsABSTRACT This paper introduces an efficient algorithm that jointly estimates differential time delays and frequency offsets between two signals. The approach is a two-step procedure. First, the differential frequency offsets are estimated from measurement of the autocorrelation functions of the rec...1992
5 Mathews, V. JohnQR-decomposition based algorithms for adaptive volterra filteringAbstract - In this paper we present a pair of QR-RLS adaptive algorithms for second-order Volterra filtering. The algorithms are based solely on Given's rotations. Hence both the algorithms are numerically stable and highly amenable to parallel implementations. The computational complexity of one of...1992
6 Mathews, V. JohnMultiplication free vector quantization using the L 1 distortion measure and its variantsVector quantization is a very powerful technique for data compression and consequently, it has attracted a lot for attention lately. One major drawback associated with this approach is its extreme computational complexity. This paper fist considers vector quantization that uses the L1 distortion mea...1992
7 Myers, Chris J.Direct synthesis of timed asynchronous circuitsThis paper presents a new method to synthesize timed asynchronous circuits directly from the specification without generating a state graph. Our synthesis procedure begins with a deterministic signal transition graph specification to which timing constraints can be added. First, a timing analysis ex...1992
8 Normann, Richard A.; Abbasi, Masoud; Johansson,TorbjornSilicon carbide enhanced thermomigrationThe widespread acceptance of thermomigration technology to produce through-chip interconnects has been impaired by (i) a random walk of the Si-Al liquid eutectic inclusion as it traverses the wafer, and (ii) a ?surface barrier? which allows thermomigration of only relatively large inclusions. In ...Silicon Dioxide; Thermometers; Transducers; Thermomigration Technology; Infrared Lamps1992
9 Mathews, V. JohnVector quantization of images using visual masking functionsABSTRACT This paper presents an image compression technique that incorporates visual masking functions in vector quantizer systems. Visual masking functions provide a description of the maximum amount of noise that can be present in an image, while remaining undetected when the image is viewed by ...1992
10 Mathews, V. JohnSubband vector quantization of images using hexagonal filter banksAbstract Results of psychophysical experiments on human vision conducted in the last three decades indicate that the eye performs a multichannel decomposition of the incident images. This paper presents a subband vector quantization algorithm that employs hexagonal filter banks. The hexagonal filte...1992
11 Stringfellow, Gerald B.Effect of oxygen incorporation in semi-insulating (AlxGa1-x)yIn1-yPDiscusses a study conducted on oxygen-doped, semi-insulating layers of (aluminum-gallium) indium phosphide grown on gallium arsenide using organometallic vapor phase epitaxy. Effect of oxygen doping on semi-insulating layers of the substance; Secondary-ion mass spectrometry measurements; Measured co...Inactive interstitial atoms; Energy-dispersive spectoscopy; intentional oxygen1992
12 Stringfellow, Gerald B.Tertiarybutyldimethylantimony: a new Sb source for low temperature organometallic vapor phase epitaxial growth of InSbThis article investigates tertiarybutyldimethylantimony as a source for low-temperature organometallic vapor phase epitaxial growth of indium antimonide (InSB); extraction of good surface morphology InSb layers; efficiency of InSB growth; and, presence of a negligible parasitic reaction between trim...Tertiarybutyldimethylantimony; Indium antimonide crystals1992
