    Aided by a growing realization of the complexity of the problems involved and stimulated, no doubt, by the spectacular successes of the systems approach in such areas as the space and defense programs, there has been in recent years an increasing interest in the utilization of the systems approach for developmental problems. A survey of the views and activities of some U.N. bodies regarding the ap... View full abstract»

    Industrial societies have evolved under the influence of a political-economic reward system and a technological revolution that literally views the environment as infinite in its waste absorbing capabilities, if not in resource producing capability as well. As such they are not ecologically feasible in the long term. It is precisely their inconsistencies with the laws of material and energy balanc... View full abstract»

    The synchronous longitudinal guidance (SLG) approach to allocating guideway space and controlling traffic in a ground transportation network is described in this paper. The transportation system considered is one in which completely automated vehicles follow deterministic position-time profiles during their travel through the network. The key feature in the SLG approach is a dynamic scheduling alg... View full abstract»

    A class of linear systems is studied which is subject to random failures. In such systems the designer must specify strategies for both control and repair. The dynamic interaction of these two facets of the problem is explored, and it is shown that quick repair permits a reduction in gains in the feedback loop. An algorithm is presented for finding the optimal controller and the best policy of rep... View full abstract»

  • Optimization and Simplification of System Models Characterizing an R&d Process

    Publication Year: 1972, Page(s):347 - 352
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (845 KB)

    Recent developments in modern control theory and high-speed computation techniques have enabled extensive treatment of complex processes. A method is presented for building a model of an R& D process utilizing the state space approach. The specific model described in this paper contains 21 state variables and a control vector of 6 components. Its formulation leads to the Mayer's problem with inequ... View full abstract»

    A predictive model is presented that represents the human as an information processor by mathematically simulating the results of past psychological research in choice reaction time, memory storage/ retrieval, and perceptual information processing. Both discrimination and identification tasks are characterized by ideal decisions with additive Gaussian noise. In an information processing task both ... View full abstract»

    Any effective model of a nontrivial portion of the nervous system cannot possibly account in detail for the activity of individual cells. We have developed an approach to modeling cortical systems by taking advantage of the regularities of the macrostructure and the stochastic nature of the spatial microstructure and temporal activity. A gross linear or nonlinear description is found for the local... View full abstract»

    An auditory display in a dual-axis compensatory tracking task was studied. Subjects were presented concurrently with the primary task of controlling a second-order plant and the secondary task of controlling a first-order plant. The plant errors for the two tasks were shown on separate visual displays. An auditory display, whose output varied in frequency and volume with the error, was used to sup... View full abstract»

    Thinking in the human brain greatly depends upon association mechanisms which can be utilized in machine intelligence. An associative memory device, called " Associatron," is proposed. The Associatron stores entities represented by bit patterns in a distributed manner and recalls the whole of any entity from a part of it. If the part is large, the recalled entity will be accurate; on the other han... View full abstract»

    An on-line learning control system involving the control of processes whose mathematical description is incomplete or insufficiently known to the controller is investigated. The controller does not identify the process but finds instead from its own accumulated experience a number of points on hypersurfaces which gradually approach the control law of the system. These hypersurfaces are approximate... View full abstract»

    An effective on-line procedure is presented for system identification and state estimation for multiple-input multiple-output linear systems. The proposed solution offers consistent system identification, bounding of the steady-state covariance, and computational savings. Also, this solution is applicable to a larger class of problems than previously proposed solutions. View full abstract»

    The development and comparison of a class of nonparametric probability density function modeling algorithms is presented. Each algorithm Iteratively estimates a model of the sampled density function based upon a description of a set of equiprobable regions over the range of the variable of interest. Minimization of computational complexity and memory capacity while maintaining convergence and stab... View full abstract»

    The convergence properties of a nearest neighbor rule that uses an editing procedure to reduce the number of preclassified samples and to improve the performance of the rule are developed. Editing of the preclassified samples using the three-nearest neighbor rule followed by classification using the single-nearest neighbor rule with the remaining preclassified samples appears to produce a decision...

    One aspect of a new theory of feature perception is considered. An algorithm is presented which can perceive and locate various features of a pattern by analyzing a statistic of the "chords" of the pattern. The procedure is illustrated by applying the algorithm to a pattern containing the Muller-Lyer figures. In measuring the length of the figures it is found that the algorithm has a visual illusi...
