The paper investigates barriers to innovation in epedagogy, seeks answer to the following basic question: "why teachers underutilize innovative tools?". The Authors report on a case study that was carried out at the Silesian University of Technology. Teachers using the Moodle learning platform were surveyed to see: 1) to what extent they made use of its different elements, 2) identify barriers in e-learning development and see teachers' general opinion about this form of education. Firstly, based on the survey results, comments related with these two groups of questions are given, then some general conclusions are drawn. Answer to the basic question is given as well, however no special recommendations for ensuring that teachers embrace rather than resist a move to e-education are offered. It looks that "carrot and stick" is the only effective policy that is able to force teachers to leave their "classroom kingdom".

Web-based blended learning at Silesian University of Technology, Poland, is supported by integrated elearning service called Distant Education Platform (DEP). The authors discuss general framework concerning DEP and present the ideas of DEP-based knowledge delivery. Introduction of modern technologies has changed education process significantly. The quality of courses supported by DEP has been improved, the number of services has increased and the teachers' workload has been reduced. Nevertheless, the number of courses that have been fully transformed into blended version is insufficient. There are many barriers to successful implementation of web-based learning - technical, mental and pedagogical. In the paper the authors present comprehensive list of potential barriers, and give some guidelines how to overcome them.
Peer-to-Peer (P2P) networks are largely used for file-sharing and hence must provide efficient mechanisms for searching the files stored at various nodes. The existing structured P2P overlays support only "exact-...

This work presents the co-simulation approach to the analysis of control systems containing detailed models of electromagnetic and electromechanical converters. In this method of analysis the attention is paid to the whole system and not only to its electromagnetic part. The latter is described by equations resulted from the two-dimensional finite element discretisation of the Maxwell equations, and is coupled weakly with the remaining part of the system. The simulation is carried out in Matlab/Simulink environment wherein the coupling is realised through the S-function. Example results regarding simulation of the operation of the control system of an electrical machine and the operation of a power electronic converter are presented and compared with available reference data.
Failure detection is a fundamental building block for ensuring fault tolerance in large scale distributed systems. In this paper we present an innovative solution to this problem. The approach is based on adaptive, de...

Iterative learning control can be applied to systems that repeat the same task over a finite duration with resetting to the starting point once each one is complete. The idea of iterative learning control is to make use of information from previous executions of the task in order to update the control signal applied during the current execution and thereby sequentially improve performance. This form of control can be treated as a class of 2D systems. In this paper, a critical overview of progress on this application area for 2D systems theory is given, including results from experimental verification on a gantry robot, and discussion of some open research questions.

In this paper we are advocating for the development and adoption of mainstream online real-time barcode reading systems that go beyond common current usage scenarios. The goal is to deliver a reliable and accessible alternative to native applications and proprietary readers. As such we analyze resource dependencies and limitations from a fresh and unconventional perspective in relation to the "in-browser" environment. To attain this feat we propose two barcode service delivery systems: the first one, a modular client-oriented detection framework suited for immediate implementation and the second one, a hybrid system designed for complex cloud infrastructures.
