    In a recent paper Bierman presented an efficient time propagation technique of the U - D covariance factors for the form \phi P\phi^{T} , when the transition matrix \Phi has a block triangular structure. This note contributes some useful remarks related to the paper, and also present... View full abstract»

    A flexible and systematic way for the construction of Lyapunov functions which lends itself to the use of nonlinear programming techniques is presented. The class of Lyapunov functions obtained is shown to be energy functions (Hamiltonians) for an equivalent system. View full abstract»

    Recently, there have been a number of attempts to apply optimal control theory to the analysis of human and animal movement. Because normal movements are very complicated and difficult to analyze, an experimental task that is easier to model and analyze has been chosen. Experimental subjects were instructed to jump as high as possible while keeping their knee and hip joints fully extended and thei... View full abstract»

  • Biasedness properties for a class of Kalman-like estimators

    Publication Year: 1983 , Page(s): 1048 - 1051

    A model for observing the system state under multiplicative and additive noise conditions has been recently proposed to extend the well-known Kalman estimation theory. In the present correspondence we investigate the biasedness properties for the best linear recursive estimator of such a model, and discuss means for adjusting the generally nonzero bias term of the estimator.

    In this paper we carry out a detailed analysis of the multiple time scale behavior of singularly perturbed linear systems of the form \dot{x}^{\epsilon}(t) = A(\epsilon)x^{\epsilon}(t) where A(\epsilon) is analytic in the small parameter ε. Our basic result is a uniform asymptotic approximation to View full abstract»

  • A lattice algorithm for factoring the spectrum of a moving average process

    Publication Year: 1983 , Page(s): 1051 - 1055
    Cited by:  Papers (7)

    Triangular decomposition of the semi-infinite covariance matrix of a moving average process can be used as a spectral factorization technique. An efficient lattice algorithm is derived for performing the necessary computations. This technique is a special case of the fast Cholesky decomposition of stationary covariance matrices. The algorithm can be used to factor multichannel spectra to a desired... View full abstract»

  • Optimal flow control of a class of queueing networks in equilibrium

    The problem of optimum flow control of a class of queueing systems which appears as a model of datagram and virtual circuit computer communication networks is investigated. This class "intuitively" has the property that by increasing the load on the network, both the average throughput and the average time delay also increase. It is shown that the control that achieves the maximum throughput under... View full abstract»

  • The Nash solution of an advertising differential game: Generalization of a model by Leitmann and Schmitendorf

    In this paper the differential game between two profit maximizing firms considered in [15] is extended to the case of general (concave) effectiveness functions of advertising. For this model, a phase portrait analysis of Nash equilibrium solutions is carried out providing qualitative insights into the structure of optimal advertising rates. Applying this analysis to the Leitmann-Schmitendorf adver... View full abstract»

  • A game-theoretic view of two processes using a single resource

    Two processes are served on a first-come, first-serve basis by a single resource (server). The thinking and resource holding times of both processes are exponential with different parameters. It is proved that, under a scaling condition, no cooperation of the processes can improve both of their resource utilizations. View full abstract»

    In this paper the problem of sensitivity, reduction by feedback is studied and related to a problem of decentralized control. A plant will be represented by an N \times N matrix of frequency responses, which may be unstable or irrational. The object will be to find conditions on P(s) under which a diagonal feedback View full abstract»
