The article describes the use of a number of alternative blended learning models based on a mixture of traditional face-to-face classes with some elements of e-learning in the course of “English for Academic Purposes” (EAP) and “English for Specific Academic Purposes” (ESAP) taught to junior and senior undergraduate students of computer sciences in the undergraduate program of Business Informatics and Software Engineering over a period of time from 2009 to 2012 at the National Research University Higher School of Economics (NRU HSE), Moscow, Russia
The present paper is devoted to the research of controlled queueing models at control of CBSMAP-flow, Controlled Batch Semi-Markov Arrival Process (Kashtanov, Kondrashova 2012). The control is based on the theory of controlled semi-markov processes and used for the system optimization. The control is carried out using the choice of the next batch type.
The three already traditional volumes of the WDS Proceedings you are holding in the hands are composed of the contributions which have been presented during the 21st Annual Conference of Doctoral Students that was held in Prague, at Charles University, Faculty of Mathematics and Physics from May 29 to June 1, 2012. In this year, 100 student manuscripts were submitted to publishing and 88 were accepted after the review process.
The paper describes the method of finite element simulation of shape rolling process based on 2,5D techniques which is due to the number of simplifications, allows to increase the rate of calculation considerably (by comparison with 3D modeling). To verify this technique the comparison of model results with data obtained at the metallurgical plant Trinecke Zelezarny within the special industrial testing was performed. The comparison confirmed the adequacy and effectiveness of the proposed models and computer system developed on their basis.
