    The authors investigate the layer assignment problem that occurs in the design of multichip modules (MCMs). An MCM is a high-performance compact package for the interconnection of several hundred chips, which are interconnected by several thousand nets. The aim is to place each net on an x-y pair of layers so as to minimize the number of such layers, with the constraint that the nets do not inters... View full abstract»

    Summary form only given. The authors apply the result established by A.N. Michel et al. (1992) to systems of differential inequalities. By using the differential inequalities to dominate a class of nonlinear systems, they obtain some new results on robust stability of the nonlinear systems. They show that, when applied to linear systems, these results yield robustness criteria which are considerab... View full abstract»

    A control scheme for parallel-connected converter systems that will transfer the maximum available power from a nonideal voltage source is presented. Monitoring the rates of change in both the average input current and the average input power from the source, the proposed control scheme can dynamically regulate the DC-DC converter system to track the peak power point of the source. The amplitude a... View full abstract»

    The authors describe a hand shape recognition method for man-machine interfaces using a pipeline image processor. The basic strategy is to use simple but effective real-time dynamical image processing to enhance the reliability of hand shape recognition. Low-level image processing reduces the data required for recognition of a hand shape. An algorithm for a noncontact-type hand shape recognizer ha... View full abstract»

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (572 KB)

    A global optimization algorithm is introduced which generalizes H.J. Kushner's (1964) univariate search. It aims to minimize the number of probes required for a given confidence in the results. All known probes contribute to a stochastic model of the underlying score surface, and this model is interrogated for the location most likely to exceed the current result goal. The surface is assumed to be... View full abstract»

    The authors present a tool for general purpose local optimization. Randomized combinatorial search heuristics such as simulated annealing (SA) are an effective means of exploring function space to find regions of high performance. Their ability to optimize functions once regions of high performance are found is limited. To improve, and accelerate, their local optimization capabilities, a perturbat... View full abstract»

    Publication Year: 1992, Page(s):306 - 310 vol.1
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (260 KB)

    Principal component analysis is used to decompose a large scale dynamic system into robust subsystems. Decentralized state estimators are then designed to observe the states of the individual subsystems. The estimators are useful in the identification of states which are strongly controllable and/or strongly observable in the inputs and outputs, respectively. The decentralized estimators have few ...

    The authors present a new algorithm for stereo matching which makes use of simultaneous feature matching, surface reconstruction and segmentation. Each of these three phases is described. The algorithm integrates these three related subprocesses in the process of extracting surfaces from stereo data. The integration is synergetic: the whole is greater than the sum of the parts.
