    This theoretical analysis of the intuitive and diffuse characteristics of analogical reasoning processes is the first step in a research effort intended to lead to: understanding of common (and possibly costly) errors, pitfalls, travails, and problem-solving impediments; possible recommendations for improvements to organizational structures, control and coordination processes, and management infor...

    A hybrid locomotion vehicle for use in remote maintenance of a nuclear power plant is proposed. The vehicle has five locomotion devices, each consisting of a supporting leg and a driving wheel. Each device has three degrees of freedom: leg lifting, wheel revolution, and wheel steering. These degrees of freedom and the inclusion of touch sensors for obstacle detection enable flexible locomotion suc... View full abstract»

    Methods of joint trajectory generation for mechanical manipulators using X-spline and quartic spline functions are presented. A sequence of Cartesian knots, i.e. positions and orientations of the hand, are selected from the desired Cartesian path. Joint values corresponding to these selected knots are solved from the kinematic equation. Approximate joint paths are constructed by interpolati... View full abstract»

  • A comparison of visual and kinesthetic-tactual displays for compensatory tracking

    Publication Year: 1983, Page(s):1103 - 1112
    Cited by:  Papers (3)

    Research on manual tracking with a kinesthetic-tactual (KT) display suggests that under certain conditions it can be an effective alternative or supplement to visual displays. In order to better understand how KT tracking compares with visual tracking, both a critical tracking and a stationary single-axis tracking task were conducted with and without velocity quickening. In the critical tracking t... View full abstract»

  • A Whirl decomposition of stochastic systems based on the substitution property

    Publication Year: 1983, Page(s):1113 - 1118
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1054 KB)

    A new method is proposed for realizing a stochastic system from interconnected smaller stochastic systems. Each smaller stochastic system considered is composed of two states. The basic tool is the partition with a substitution property which exists on the transition matrix of the interconnected stochastic system. Using the authors' method, a stochastic system with n states is decomposed in... View full abstract»

  • An a priori identifiability condition and order determination algorithm for MIMO systems

    Publication Year: 1983, Page(s):1119 - 1128
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1592 KB)

    The identification of deterministic multi-input multi-output (MIMO) systems is studied. An a priori condition for determining the identifiability of stable and unstable MIMO systems is derived. The condition also determines the minimum length data sequence which will allow successful identification. In addition, an algorithm is presented for determining the order of the system prior to identifying... View full abstract»

  • Improved formulations to the hierarchical health facility location-allocation problem

    A.B. Calvo and D.H. Marks (1973) formulated the problem of locating various types of health facilities, and allocating different types and levels of demand to these facilities, as a zero-one integer programming model. Although the model has been widely referenced in the literature no solution algorithm has been developed to date. It is shown in this work that the model is actually only locally inc...

  • A phased plan for an electric passenger car demonstration: An analysis of planning needs

    Publication Year: 1983, Page(s):1132 - 1135
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1129 KB)

    The criteria for successful demonstrations are reviewed, these criteria are then applied to electric vehicles, and a phased plan is presented for electric vehicle demonstrations supported mainly by the private sector. The phased plan includes a sequence of activities of exploratory study, field tests, and demonstration planning before a costly demonstration is carried out. View full abstract»

  • Moments of the interclass Mahalanobis distance

    Publication Year: 1983, Page(s):1135 - 1139
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1113 KB)

    It is shown that the moments of the interclass Mahalanobis distance between elements of two d-variate Gaussian populations can be expressed in a simple polynomial form. The nth moment is expressible as a polynomial of order n whose variable depends on the mean vectors and eigenvalues of the covariance matrices. A closed-form solution is given for computing the coefficients of ... View full abstract»

  • Varying null locations and the number of nulls in DFT windows

    Publication Year: 1983, Page(s):1139 - 1143
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1205 KB)

    An approach is presented for varying the discrete Fourier transform (DFT) frequency response by the use of a weighting sequence derived from convolved weightings. The nulls of the response may be varied within a finite set while maintaining low-amplitude sidelobes. The method is attractive when the DFT is mechanized with Winograd's small N algorithms.

  • Learning automata processing ergodicity of the mean: The two-action case

    Publication Year: 1983, Page(s):1143 - 1148

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1470 KB)

    Learning automata which update their action probabilities on the basis of the responses they get from an environment are considered. The automata update the probabilities whether the environment responds with a reward or a penalty. An automation is said to possess ergodicity of the mean (EM) if the mean action probability is the total state probability of an ergodic Markov chain. The only known EM... View full abstract»

    Results of a study are summarized in which quadtrees were used to encode the regions in three map overlays representing a small area in northern California. Programs were then written to perform various analysis and manipulation tasks on the quadtree-encoded regions. Data is provided on the compactness of the encodings and the efficiency of the programs.

  • An N-player sequential stochastic game with identical payoffs

    Publication Year: 1983, Page(s):1154 - 1158
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1378 KB)

    A sequential stochastic game among an arbitrary number of players in which all players' payoffs are identical is analyzed. The players are unaware that they are in a game and hence they have no knowledge of other players' strategies or the payoff structure. At each instant the players use a simple learning algorithm to update their mixed strategy choices based entirely on the response of a random ... View full abstract»

  • Classification and tracking using local optimization

    Publication Year: 1983, Page(s):1158 - 1162
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5688 KB)

    When a heuristic function is available to evaluate classification, a special search procedure is applied to find a classification optimizing this function. A specific application to image segmentation is presented, including several examples. The major difference between this approach and previous optimization attempts is the use of deterministic rather than probabilistic classifications. The appr... View full abstract»

    The information structures associated with deterministic decentralized control are examined. Conditions are derived under which such structures are partially nested. The tuning regulator approach and the sequential optimization approach are used as examples to examine these conditions in the context of concrete decentralized controller design philosophies.

    The redundancy in computation for median filtering, mean filtering, and point and line detection in two-dimensional images is considered. Fast algorithms are described for median evaluation with 3×3 and 5×4 window sizes. The algorithms are compared with existing ones, and the test result on a picture is given. Extension of the algorithms for mean filtering and point and line detectio... View full abstract»
