TL;DR: In this article, the effectiveness of the discrete sine transform (DST) in terms of residual correlation as developed by Hamidi and Pearl[1] is investigated. And the odd-even property of the DST is established.

TL;DR: In this article, a floating point representation for exact conversion of decimal numbers is discussed, which requires the exponent to represent a power of ten, and thus decimal shifts of the binary mantissa are needed.

TL;DR: In this paper, the use of an observer in power system control is considered and the observer-controller considered here is of lower order than that of the Luenberger observer controller used in previous work.

TL;DR: Algorithms For Weighting Matrices required to implement the Sampled-Data Linear Optimal Regulator Problems are developed.

TL;DR: This paper is concerned with the design of a discrete-time regulator by using an observer in conjunction with a state feedback law by using Krylov's transformation to design feedback laws that achieve eigenvalue placement.

TL;DR: In this article, a simple disjunctive decomposition with one free variable is obtained by using the prime implicants of the Boolean function, and a necessary and sufficient condition is that the variable remains present, in either true or complemented form, in all the prime Implicants.

TL;DR: A new necessary and sufficient condition has been proposed to check the p-t diagnosability of the system, and assuming that failure probability of each unit is a priori known, this measure is used to study the diagnosable of digital systems.

TL;DR: In this article, a reduced order adaptive filtering algorithm was developed for estimating the state of a finite dimension linear, time-varying, discrete-time, stochastic system having cross correlated white measurement and disturbance noises.

TL;DR: In this article, a hybrid simulation technique for identification and steady state optimization of a tubular reactor used in ammonia synthesis is presented, which finds the catalyst activity factor and certain heat transfer coefficients that minimize the sum of squares of deviation from simulated and actual temperature measurements obtained from an operating plant.

TL;DR: The authors conjecture that the design process is equivalent to an optimal control problem which seeks an admissible control effort on state variables (taxonomies) within the confines of modern control theory.

TL;DR: In this paper, the principle of operation of variable reluctance and permanent magnet motors, electrohydraulic stepping motors and the design of low and high performance stepping motor drives are discussed.

TL;DR: Analysis of the behaviour of the slotted-ALOHA random access satellite channel reveals that significant reduction in the delay can be achieved by this technique employing only a few strata.

TL;DR: The on-line identification techniques of process dynamics are surveyed and emphasis has been placed on recent developments related to the numerical behavior of algorithms.

TL;DR: In this paper, the partial differential equation that characterizes variable time delay is analyzed, and a class of variable delay approximations is developed from which several commonly used approximateations follow as special cases.

TL;DR: A new technique is suggested for the accurate analysis of the linearly-graded p-n junctions which permits one to calculate the built-in voltage and the depletion region width under equilibrium conditions.

TL;DR: The procedure is heuristic and starts from typical properties of (4 × 1) Karnaugh map obtained by entering variables to determine the total set of minimum MUX networks of a given logical function.

TL;DR: A quality factor measurement is introduced which predicts the degree of distinguishability among pairs of pattern classes, and which is shown to be particularly relevant in relation to n -tuple pattern classifiers.

TL;DR: A new dominant-data matching method is presented to redesign the high-order stabilization filter for obtaining reduced-order filters, and the implementation cost is reduced and the reliability increased.

TL;DR: In this article, a decoupling and pole-placement technique has been developed for the ASPS of the Space Shuttle which uses bandwidths as performance criteria, and the dynamics of the continuous-data ASPS allows the three degrees of freedom to be totally decoupled by state feedback through constant gains.

TL;DR: In this article, a method for system identification using sampled values of the initial transient step or impulse response is described, where a polynomial fit of the sampled values is made using Lagrange interpolation and the Laplace transform of the output observed is determined.

TL;DR: Algorithms for realizing adaptive control are introduced and the recent trend towards distributed control is highlighted.

TL;DR: The fanout-free networks are studied using the graph-theoretic approach and results in several standard realization patterns, which are discussed on the future potential of this approach.
