New methods for designing and analyzing fuzzy controllers are required. Some architectures for integrating genetic algorithms with fuzzy logic controllers, the so called hybrid geno-fuzzy controllers, are introduced and discussed. A new hybrid geno-fuzzy controller based on the algebraic model...

The subject of this work is the numerical analysis of a special finite element for the numerical solution of Naghdi cylindrical shell problems. Its discretization with standard finite elements suffers from the locking phenomenon, i.e., when small thickness shells are solved, the numerical...

Empirical modeling of the industrial antibiotic fed-batch fermentation process is discussed in this paper. Several methods including neural networks, genetic algorithms and feature selection are combined with prior knowledge in the research methodology. A linear model, a radial basis function...

Ill-posed problems described by first-kind Fredholm equations appear in many interesting practical cases in engineering or mathematical physics, such as the inverse problem of signal deconvolution, and require regularization techniques to get adequate solutions ([C. Sánchez-Ávila, A.R....

The investigated global geodyanmic model of the Earth is described by an initial boundary value problem for a coupled system of equations of motion in Bingham visco-plastic rheology, equation of Stefan-like problem (describing melting, recrystallization and solidification processes in the...

In contact mechanics, a problem might arise when at least one of the contacting bodies is not fully fixed, i.e. the corresponding functional is semicoercive. The paper will deal with numerical methods for these cases. The fundamental Uzawa method for a class of problems does not converge...

Academic and applied researchers in economics have, in the last 10 years, become increasingly interested in the topic of chaotic dynamics. In this paper we undertake non-linear dynamical analysis of one representative time series taken from financial markets, namely the Standard and Poor's (S&P)...

This paper proposes a direct adaptive fuzzy-model-based control algorithm. The controller is based on an inverse semi-linguistic fuzzy process model, identified and adapted via input-matching technique. For the adaptation of the fuzzy model a general learning rule has been developed employing...

While proving compositeness of a natural number is a computational task that can be easily done in polynomial time, proving primality of an arbitrary positive integer is a harder task. Only two main streams of useful algorithms are known in this direction: elliptic curve primality provers...

This paper gives the results of earthquake response analysis of nuclear power plant buildings in accordance with the methodology of seismic margin assessment and generic implementation procedure. Earthquake resistance of all the important buildings was considered taking a dynamic effect on...
