This approach leads to a class of adaptive controllers that, in many cases, are completely linear and time-invariant. A representative example of one of these all-linear, time-invariant adaptive controllers is analytically examined from the classical transfer function viewpoint. This analysis reveals a unique mathematical structure of the controller's transfer function, which provides a simple explanation for the controller's remarkable adaptive capabilities.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

Incomplete conditions are defined as having insufficient conditions in the inference chain. The authors propose a precise representation and interpretation of the rule-based system with clear guidelines given for the meaning of the uncertain conditions and the resulting conclusions. To facilitate the accurate evaluation of the incomplete conditions, weighting factors are used and assigned to each antecedent relative to other antecedents in the same rule. These weighting factors are determined by the domain experts and knowledge engineers during knowledge acquisition periods based on three proposed elements, the significance of which is discussed.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

Such a procedure requires an initial value, a step size, and a range over which the eigenvalues are sought. To be sure that an eigenvalue has not been missed by the search, it may be necessary to find all eigenvalues. To do so may require new starting values, search increments, and ranges. The authors develop an efficient procedure for finding the eigenvalues in a dynamic transfer matrix analysis. All eigenvalues are obtained simultaneously by the convergence of a matrix equation. The convergence does not depend upon the initial eigenvalue estimates, which may be arbitrary, and the need for search increments and range estimates is eliminated.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

It is assumed that the physical process is represented by a system of partial differential equations of known form but containing unknown parameters. A sequential parameter identification algorithm is developed to estimate the parameters for two distributed-parameter plug flow models, namely the one- and two-temperature-plug-flow models that are used to describe the dynamics of a solar collector. The problem is put into the general framework of a nonlinear identification problem which is solved by a nonlinear recursive least-square (NRLS) algorithm. The NRLS algorithm is used to estimate the model parameters from both stimulated and experimental data taken from Colorado State Universities Solar House III.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

The signal is represented as a trajectory in the first-order phase plane, from which a set of features is extracted including uncoded and coded intersection number with the x- and y-axes, respectively. Both nearest-neighbor and K-means clustering are used for classification. The feature set was evaluated for speaker-invariant recognition using an orthographic (written) vowel data. Among the features selected, the uncoded intersection number provided much tighter clustering in the decision space with an error rate of 10% using nearest-neighbor classification.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

Pulse de-interleaving techniques that can be used in this situation fall into the following categories: time-of-arrival de-interleaving, pigeon hole de-interleaving, and de-interleaving using metric techniques. The authors give a review of these techniques and their limitations in performance in the presence of frequency-agile and pulse-repetition-interval-agile radars. Three algorithms for ESM data processing are also discussed. An adaptive cell size de-interleaving approach dynamically optimizes the cell dimension based on the criterion described. The algorithm has been tested in a simulated ESM data processor. The implementation of the algorithm together with program and data structures are given. The approach and structure of moving cell algorithm and bulging cell algorithm are also discussed.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

The authors developed an operating system that allows their multicomputer system to be used in user, star, queue, and pipeline processing modes.
