Using the underlying idea of the current-mode control, a new dynamical, sliding-mode control for the boost dc-dc converter is proposed. Such controller is easy to design, robust under load and input voltage variations, exhibits fast response, does not depend on…

This calculation is based on calculation of torque components of induction machines. Basic torque components are expanded, using knowledge of machine’s geometry, to the periphery of machine’s rotor. Using Fourier analysis of torque components it is possible to calculate forces…

For the expansion of PLC systems, it is necesssary to have a detailed knowledge of the PLC transmission channel properties. This contribution shortly discusses characteristics of the PLC environment and a classification of PLC transmission channels. A main part is…

This article takes down the knowledge with determination of criteria weights in the terms of computer software of superconductive materials. This software relieves processing of considerable enters data. The criteria of the weights were determinated by Fuller triangle and Saaty´s…

This article offers a critical synthesis of the knowledge obtained in the wake of the work of the Comite d’experts sur l’apprentissage de l’écriture (Committee of experts on learning to write), which published a report entitled, « Mieux soutenir le…

In this paper, a method of event ordering based on temporal information resolution is presented. This method consists of two main steps: on the one hand, the recognition and resolution of the temporal expressions that can be transformed on a…

Durante la preparación de la selección junior autonómica de remo (Comunidad Valenciana, España), se recogieron las características antropométricas de 18 remeros junior masculinos de edad 17,83±3,83 años. A los remeros se le realizaron una valoración anthropometry mediante la técnica basadas…

Although there is a general understanding of Montagu’s harrier migration routes and wintering areas, detailed information on the species’ migration is still lacking. However, improvements in satellite tracking technology in recent years have enabled the study of medium-sized species by…
