An extended query-the-user tool for expert systems
(Cognizant Communication Corp, 1998-01-01)
An extended version of HIER, a query-the-user facility for expert systems is presented. HIER was developed to run over Prolog programs, and has been incorporated to systems that support the design of large and complex ...
NASH game and mixed H2/H∞ control
(Institute of Electrical and Electronics Engineers (IEEE), 1997-01-01)
In this work a Nonzero-Sum NASH game related to the H2 and H∞ control problems is formulated in the context of convex optimization theory. The variables of the game are limiting bounds for the H2 and H∞ norms, and the final ...
A novel voltage step-down/up ZCS-PWM Zeta converter
(Institute of Electrical and Electronics Engineers (IEEE), 2000-01-01)
This paper presents an analysis of a novel pulse-width-modulated (PWM) voltage step-down/up Zeta converter, featuring zero-current-switching (ZCS) at the active switches. The applications in de to de and ac to de (rectifier) ...
A heuristic for the stochastic single-machine problem with E/T costs
(International Foundation for Production Research - IFPRFoz do Iguaçu, Brasil, 2013-07-28)
This paper addresses the problem of simultaneous due-date determination and sequencing of a set of jobs on a stochastic single machine environment with distinct job earliness and tardiness penalty costs. It was assumed ...
PVis - Partitions’ Visualizer: extracting knowledge by visualizing a collection of partitions
(IEEE Computational Intelligence SocietyChinese Academy of SciencesNational Natural Science Foundation of ChinaBeijing, 2014-07)
Recent advances in cluster analysis highlight the importance of finding multiple meaningful partitions and point out to the need for approaches to evaluate them. They also suggest that the evaluation should consider knowledge ...
Convergence analysis of an elitist non-homogeneous genetic algorithm with mutation probability adjusted by a fuzzy controller
(Ieee, 2013-01-01)
In recent years, several attempts to improve the efficiency of the Canonical Genetic Algorithm have been presented. The advantage of the elitist non-homogeneous genetic algorithm is that variation of the mutation probabilities ...
On Robust Switched Controller Design to Minimize the Guaranteed Cost of Polynomial Fuzzy Systems
(2019-06-01)
This paper presents a robust switched controller design to minimize an upper bound of a quadratic index (guaranteed cost) based on the output and the control input of uncertain nonlinear systems described by polynomial ...
Identification of unsteady aerodynamic loads using aeroelastic response and orthogonal functions
(2012-01-01)
The objective of this paper is the identification of aerodynamic parameters by the use of aeroelastic response using orthogonal functions. The unsteady aerodynamic forces acting on an aeroelastic system can calculated in ...

In recent years, several attempts to improve the efficiency of the Canonical Genetic Algorithm have been presented. The advantage of the elitist non-homogeneous genetic algorithm is that variation of the mutation probabilities ...
Discrete-time design of state-derivative feedback control laws
(2013-12-01)
State-derivative feedback control laws can be very useful in the control of systems using accelerometers as sensors. Moreover, in cases where both state and state derivative measurements are available, a state-derivative ...
