Ambiguous Behavior of Logic Bistable Systems
(19751004)The standard specification of logic bistable devices do not specify the behavior under conditions in which the input is logically undefined or in which certain kinds of multiple input changes occur. These conditions are ... 
DYNAMAN: A Tool for Manipulator Design and Analysis.
(1985)This report describes a method to formulate the dynamic equations of a robot manipulator with N links and with either revolute or prismatic joints using a NewtonEuler formulation. A general purpose tool for analysis and ... 
A Simple Proof of Stability on the Center Manifold for Hopf Bifurcation.
(1985)A simple proof is presented for a well known fact about Hopf bifurcation: if the loss of an equilibrium point results in periodic solutions via Hopf bifurcation, then the stability ot these periodic solutions is determined ... 
On the Stability of Multiple TimeScale Systems.
(1985)The stability of timeinvariant multiparameter singular perturbation problems is considered and the implications of two timescale stability results for multiple timescale systems are clarified. An example shows that the ... 
Strong DStability.
(1985)A square matrix F is said to be Dstable if the eigenvalues of DF have negative real parts for any diagonal matrix D with positive diagonal elements. The perturbational properties of Dstability and block Dstability, a ... 
Decomposition and Decentralized Control System Design: A Review of Frequency Domain Methods.
(1985)We provide a short review of the literature on design of decentralized control based on weak coupling measures for transfer function models. The notion of diagonal dominance for transfer functions has been suggested as a ... 
Characterization and Efficient Computation of the Structures Singular Value.
(1985)The concept of structured singular value was recently Introduced by Doyle (Proc. IEEE, vol. 129, pp. 242250, 1982) as a tool for the analysis and synthesis of feedback systems with structured uncertainties. It is a key ... 
Stochastic Unit Commitment Scheduling and Dispatch of Electric Power Systems.
(1985)Unit commitment, including economic dispatch, is a key component of short term operation scheduling of an electric energy system. Common industry practice is based on the use of a 'priority list' for generation scheduling ... 
Two Case Studies in OptimizationBased ComputerAided Design of Control Systems.
(1985)There have been many approaches proposed for the computeraided design of control systems. The coauthors of this paper include several strong proponents of a design methodology emphasizing designer's intuition, manmachine ... 
Towards Intelligent Design Optimization.
(1985)A strategy for design optimization of nonlinearly constrained problems is presented. The strategy combines techniques used in production rule systems with an optimization procedure dealing with local monotonicity and with ... 
Convergence of Implicit Discretization Schemes for Linear Differential Equations with Application to Filtering.
(1985)This paper presents a generalization of results on convergence and robustness of discretization schemes for nonlinear filtering proposed by Kushner. This is made possible by a general theorem on the convergence of semigroups ... 
RealTime Default Reasoning, Relevance, and Memory Models.
(1985)We describe a working example of mechanical default reasoning that is rather robust, in that it can detect a conflict between a default conclusion and another assertion (or conclusion), can (under suitable conditions) ... 
Integration of Computer Aided Design and Computer Aided Process Planning.
(1985)In recent years, CAD/CAM systems have gained wide acceptance in industry. As experience in the use of these systems builds up, it is becoming increasingly evident that for most effective operation, they must be integrated. ... 
A New Parameter Estimate in Singular Perturbations.
(1985)A new upper bound is obtained for the singular perturbation parameter of an asymptotically stable singularly perturbed system. General time invariant systems with a single small parameter are considered. The paper employs ... 
Optimal Quantizer Design for Noisy Channels: An Approach to Combined SourceChannel Coding.
(1985)In this paper, we present an analysis of the zeromemory quantization of memoryless sources when the quantizer output is to be encoded and transmitted across a noisy channel. Necessary conditions for the joint optimization ... 
An Approach for Building a RuleBased System for Design Optimization.
(1985)A strategy for design optimization of nonlinearly constrained problems is presented. The strategy combines techniques used in production rule systems with an optimization procedure dealing with local monotonicity and ... 
A Local Version of the TwoCircles Theorem.
(1985)A necessary and sufficient condition is given so that in a domain OMEGA there are no functions whose average over all balls contained in OMEGA of radii r_1, r_2 vanish except the zero function. 
A Commentary on the Literature of SelfReference.
(1985)Selfreference, far from being just a logician's and a philosopher's puzzle is, in fact, a central feature of human language and reason. It, thus, seems natural that intelligent machines will also have to deal with the ... 
Almost Sure Stability of Linear Stochastic Systems with Poisson Process Coefficients.
(1985)We consider the problem of determining the sample path stability of a linear stochastic differential equation with point process coefficients. Necessary and sufficient conditions are obtained which are similar in spirit ...
