In this paper, a dynamic fuzzy approach is proposed for the selection of an evaluation function for a genetic algorithm (GA). The GA is in turn used to optimise a neural network (NN) architecture. A correctly classified pattern in the presence of error is considered for the fitness function. Fuzzy logic is used to dynamically select the chromosome for evolution. It gives a direction of evolution as well as provides more exploration among most desirable ones in the population, by dynamically changing the range of the membership function. To increase the resolution, different heights of the membership function with increasing heights towards more feasible features are considered. Modelling of a flexible manipulator is used to show the performance of the proposed approach. Results show that dynamic fuzzy logic performs better than fuzzy logic with fixed range and height.

The paper addresses the design of a robust controller with output feedback for uncertain linear systems in the time domain. The necessary and sufficient conditions for static output feedback stabilizability of linear continuous and discrete time systems are the basis for the proposed robust controller design procedure. The proposed approach does not employ matching conditions.

Considering that neither captology nor agent-orientation, are applied in medical informatics, as they could be, the paper presents a broad-spectrum gene-ric architectural framework to support developing adaptive medical applications, based on synergistic correlation between persuasive interfaces and intelligent agents. Their main features are adapted for medical informatics. Lying on this groundwork, the design space for agent-oriented persuasive applications is defined and several guidelines for its main dimensions are given. The approach is instantiated through an agent-based test-bench application, having the purpose to persuade to quit smoking.

This work deals with the developing of Adaptive control on Manifolds algorithms (ACM) designed for the accompanying quality functionals in their general form. Our point here is to apply the ACM approach and to introduce some practice restrictions for the nonlinear control plants in the case of the quadratic accompanying functionals (QAF). In this article framework we analyze the applicability conditions of designed algorithms and illustrate received results for the problem of adaptive control of combustion engine crankshaft rotation speed.

The cell formation problem is a classic manufacturing optimisation problem associated with the implementation of a cellular manufacturing system. A variety of hierarchical clustering procedures have been proposed for the solution of this problem. Essential for the operation of a clustering procedure is the determination of a form of similarity between the objects that are going to be grouped. The authors employ a genetic programming algorithm for the evolution of new similarity coefficients for the solution of simple cell formation problems. Evolved coefficients are tested against the well-known Jaccard's similarity coefficient on a large number of problems taken from the literature.

A design approach of the initial state of the repetitive controller is proposed in this paper. The approach makes full use of the feature of the digital controller and optimizes the transient response without perplexing the controller. A numerical example is presented to illustrate the validity of the approach.
