    Interactive educational objects, or interactive elements in short, are the cornerstones of interactive teaching. Their use distinguishes “real” on-line teaching, that is teaching that requires interaction of the consumer of education with the educational material in real time, from teaching that only offers the distribution of “electronic (university) textbooks”. Recently, we have been involved in both individual and routine creation of interactive elements for hundreds of interactive educational materials. The paper focuses on the philosophy of using interactive elements in educational materials as well as didactical and pedagogical contexts and impacts. The core of the article focuses on explaining the possibilities of different types of interactive elements usage in on-line teaching as well as their advantages and limitations. The article also describes the technical processing of interactive elements in way, that enables their production in large quantities and excellent quality while keeping low costs.

    The issue of the workforce management in the field is crucial for infrastructure operators. A key role is played by workforce management systems that assign workers with the right skills at the optimal time in the right place, so long-term compliance with the required quality parameters is met at the lowest possible costs. Historical development and theoretical basics of workforce management systems are presented in the paper. Fundamental of paper is the issue of modelling and simulation of Workforce management systems. The output is simulation model. Results of simulations and their compliance with the real data are discussed in conclusion. The paper is based on extensive real data that the authors obtained from the most important Czech power distribution and telecommunications operators.

    The methodology specifies a procedure for measuring of data transmission speed for the assessment of compliance with the conditions proscribed for holders of licenses for usage frequencies in the 800, 1800 and 2600 MHz bands, for the operation of mobile systems according to the LTE standard. The achievement of specified data transmission speed is a key parameter for evaluating the coverage of the Czech Republic mobile signal for the LTE standard systems. The methodology allows to the Czech telecommunication regulatory body (Czech Telecommunication Office – CTO), telecommunications operators and end users unambiguous determination of values of speed of data transmission in mobile networks in accordance with standard LTE. The methodology treats the issue comprehensively and specifies in initial conditions of measurement, measurement procedures (both for stationary measurement and in motion measurement) and related calculations. The team of authors from the Czech Technical University in Prague created a substantial part of the described methodology.

    Smart Grids are current stage in power grids evolution. This trend brings increased demands on network management and it results in the need for greater involvement of ICT technologies to power grids. In telecommunications, managing large ICT networks is traditionally handled at high level and has been described by standardized process frameworks. One of the most important process frameworks is Frameworx by TM Forum. It is generally assumed that the processes from the telecommunications can be adapted to the Smart Grids. This paper addresses the use of existing techniques from the field of telecommunications, especially the Frameworx in the power grid sector. This aim is achieved through modeling and simulation of processes in the power grid using the processes described for telecommunications networks. The output of the paper is to assess the suitability of the usage of formalized process frameworks in the field of power grids.

    This paper presents original methodology designed for comparison of communication technologies for Smart Grids, according to their business characteristics. Its core is a detailed description of the complex of criteria for business characteristics of the communication technologies assessment, in terms of their use in Smart Grids. Part of the description is also a definition of the suitable metrics. The assessment has been designed in a way to allow the evaluation from the Smart Grids user’s point of view. All technologies have been described and sorted into individual categories and assessment of their working characteristics has been made from the point of their use for Smart Grids. Mutual comparison of results is the outcome of this article. The presented methodology has been developed within the research project that was carried out for a significant European power networks operator for strategic decision making during the determination of which technology should be chosen.

    The paper deals the issue of possibility of Smart Grids modeling, by using the method used for modeling behavior of telecommunication systems. The term Smart Grids is used to designate an intelligent power distribution network widely using computer technology to better link producers and consumers of electricity. Smart Grids emphasize the increase of automation of monitoring and control of electrical distribution networks for added reliability, efficiency and cost effective operations. The telecommunications went through a similar process in last decades. It has resulted in definition of a unified business process model of telecommunications operator (eTOM). The paper addresses the question whether it is possible to apply the experience gained in telecommunications to Smart Grids. The core of the paper is a versatile analysis eTOM operation processes with respect to their applicability for Smart Grids management. The output of the paper is an identification of telecommunications processes which can be applied to deal with Smart Grids networks management issues.
