This article gives an overview of the comprehensive system that supports training and retraining specialists in a field of information and telecommunication technologies. The system consists of LMS and a number of managed virtual environments for doing practical works in a distance learning mode.
Usage of virtual environments for creating the virtual practice support system is described. Factors are considered that significantly improve the quality of specialists training in a field of information and communication technologies.
The boor develops a new approach to the study of social reality in its denamics based on the revealing of connections between social and anthropological phenomena. The fundament of the approach is synergic anthropology, in the frame work of which the apparatus for the description and analysis or the "colonization" of the interface of the Social and the Anthropological is constructed. A new class of concepts is introduced, the categories of the interface, the examples of which are anthropological situation, anthropological trend, spiritual tradition etc. Anthropological trends serve as the main tool are developed, the diagnostics (the identification of anthropological formation(s), which generate trend in question) and the control (the stimulation of a trend, the blocking of it etc.). The framework is then applied to analysis of the most topical modern problems such as global risks, ecological crisis, the grwth of the virtualization of reality, the problem of the Post-human etc. Special attention is paid to the "Exit trend", which is how we call the overall anthropological trend collecting all manifestations and tendencies of the specific tiredness of the Human and his/her drive to a self-withdrawal. Using our methods of the control of trends, it is possible to formulate strategies for changing and correcting anthroposocial situation. We find that two phenomena play important role in these strategies, the transition of modernity into the postsecular paradigm, and the return of the Onthological Human, the fnthropological formation constituted in religious expirience and forced out by the po\rocesses of secularization. In the conceptual context of modern social philosophy the approach uniting social and anthropological reality in a new light, and provides new principles for determining our attitudes and strategies towards leading trends of modernity.
The use of hardware virtualization for ensuring information security is discussed. A review of various approaches to improving the security of software systems based on virtualization is given. A review of possible scenarios of using virtualization by intruders is also presented. The application domains and limitations of the available solutions and perspectives of future development in the field are discussed.
This paper examines the changes in the ethics of business communication associated with virtualization. The transfer of business communication to virtual space alters the very process of interaction and, as a consequence, ethical principles in a professional environment.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
