    Automatic speech recognition has made significant strides from the days of recognizing isolated words. State-of-the-art systems are capable of recognizing tens of thousands of words in complex domains such as newspaper correspondence and travel planning. A major part of this success is due to advances in language modeling and search techniques that support efficient, sub-optimal decoding over larg... View full abstract»

    The objective of the paper is to explore the possibility of developing a slice based model whose random variable is independent and would fit classical distributions. The authors analyze four MPEG-1 VBR encoded high quality, color video sequences. None of the sequences contain audio. The authors present three types of slice based models and discuss the merits of each. They show the distributions g... View full abstract»

  • Modular network control for robot manipulator

    Publication Year: 1995, Page(s):183 - 187

    Plant dynamics of highly nonlinear dynamical systems often vary over its parameter space. This generates a natural partitioning of the parameter space based upon the operating points of the plant. As a result, it may be wise to generate local control strategies at, the operating points rather than a single global strategy. This article describes a modular neural network architecture that generates... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (484 KB)

    The application of genetic algorithms (GAs) to the design optimization of electromagnetic devices is presented. The method is applied to a magnetizer to design its pole face. Optimization is sought to achieve a desired magnetic flux density distribution in the device. The shape of the pole face is constructed from the control points by means of uniform nonrational b-splines. The results obtained s... View full abstract»

  • A model for a universally testable logic element

    Publication Year: 1995, Page(s):85 - 91
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (392 KB)

    A model is presented for a logic element to be used in the design of testable logic circuits. The logic element consists of a threshold gate and an exclusive-or. A circuit designed exclusively with such an element, according to the rules set here, can be tested for all data stuck-at faults. Only two predetermined test vectors are needed for testing any combinational circuit and four for any sequen... View full abstract»

    An approach for pattern recognition using neural networks is proposed. Particularly, a Boltzmann machine, a Hopfield neural net model, is used in pattern recognition with desirable learning ability. The Boltzmann machine features stochastic learning, which acts as the connection dynamics for determining the weights on the connections between the neuron-like cells (processing elements) of different...

    One organization supports files; the other supports data in memory. Two utility programs were written in the C programming language that use the organizations. One program supports entering data into a file through the keyboard; the other utility reads the file, stores the data in memory, and gives the user the option of printing some of the data to a file in a format similar to signature analysis...

    Forward and inverse kinematic models for a human like (HL) robot joint are developed and used to simulate the behavior of the joint. The forward kinematic model of the HL joint is found simply to consist of two rotational motions about fixed coordinate frames. The inverse tangent (atan2) function technique is used to develop an inverse kinematic model of the HL joint. This technique also prevents ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (392 KB)

    A computer process for reconstructing 3D objects using two spatially separated photographic images is introduced and implemented. Normalized cross-correlation is used to locate feature points which are common to both 2D images. The displacements of these feature points are used to generate disparity maps, and disparity values can be used to compute x,y,z locations. Since disparity maps are typical... View full abstract»

    Services offered within fibre-based asynchronous transfer mode (ATM) networks may range from circuit emulations, where extremely low cell loss rates are essential, to high-speed variable rate services where a degree of cell loss can be tolerated but whose bandwidth requirements may be extremely bursty and unpredictable. ATM switches deployed within these networks must be extremely robust to suppor... View full abstract»

    In many applications a task is repeatedly executed on several sets of data in a pipeline fashion. For example, image processing software is frequently executed on a sequence of images. Due to varying semantic content in the data, each subtask of the overall task may experience variations in execution time for different instances of the data. The authors consider the problem of efficiently executin... View full abstract»

    We propose an approach for compressing address traces with access patterns irregularity. This approach is based on a cluster analysis of the trace. This analysis do not rely on any locality assumption and thus is suitable in cases where the space locality is poor due to access patterns irregularity. This approach can be used efficiently as a complement to other compressing techniques which rely ex... View full abstract»

    A new algorithm for estimating the order of a non-Gaussian white autoregressive moving-average (ARMA) process using third order cumulants is described. The observed data sequence is modeled as the output of an ARMA system that is excited by an unobservable input, and is corrupted by white, zero-mean additive Gaussian noise. The new method is based on the minimum eigenvalue of a covariance matrix d... View full abstract»

    Excess electrical noise measurement was used to study the electromigration damage in thin aluminum thin films. Magnitude and frequency exponent for excess electrical noise spectra of 1/fα were measured as a function of the Al-thin film temperature. In this study very seldom excess noise with frequency exponent, α, exactly equal to 1.0 or 2.0 was encountered. The value of &al... View full abstract»

    A relatively simple and widely-used basis function in the method of moments solution for surface currents on a conducting scatterer is the piecewise linear function (triangle function). However, the triangle function does not exhibit the proper edge behavior for surface current and charge at a conducting knife-edge. The proper edge behavior is incorporated into the basis function set via a minor m... View full abstract»
