Research studying effective planning and optimization in the vehicle routing field has increased tremendously in the last few decades. Advances in technology and computational power have encouraged researchers to consider various vehicle routing problem types and constraints, and to experiment…

This paper is the survey of studies that include design processes of some fuzzy expert systems for applications in some medical area. Recent studies of us that include fuzzy expert systems that make use of fuzzy logic method were described.…

Biclustering has become a very popular data mining technique due to its ability to explore at the same time two different dimensions, as opposed to clustering techniques, that make use of only one dimension. Gene expression data offer a suitable…

Since ancient times, fishing has been a major source of food for humanity and a provider of employment and economic benefits to those engaged in this activity. However, with increased knowledge and the dynamic development of fisheries it was realized…

The aim of the article is to examine the relationship between organizational learning and strategic planning actions in SMEs. The hypothesis is that those firms that think strategic planning as an organizational learning process may encourage the design of 'long-term…

"La tesis se enfoca en el diseño de leyes de control adaptables para robots manipuladores que consideran la naturaleza acotada de los actuadores. Se proponen esquemas generalizados para regulaci on y seguimiento globales por retroalimentacion de estados,cuyas estructuras permiten obtener…

We found the linear complexity of quaternary sequences of period over the ring Z_4 . The sequences are based on Whiteman's generalized cyclotomic classes of order four. Also we derived the maximum nontrivial autocorrelation magnitude of the constructed sequences.

In this paper we consider boundary value problems with singularity in equation or solution. To solve these problems, we apply single exponential and double exponential transformations of sinc-Galerkin and Chebyshev cardinal functions. Numerical examples highlight efficiency of Chebyshev cardinal functions…
