Item Artificial neural network and ways of its optimization for some problems(2013) Didmanidze, Ibraim; Kakhiani, HryhoriiTraining effectiveness of the Multi layer neuron networks depends on the quantity of neuron layers within the network, quantity of neurons in the hidden layer and initialization ofsynaptic connections’ weight coefficients.Item Choose ofthe compression schema(2013) Didmanidze, Ibraim; Tkhilaishvili, RymaThe selection of a compression scheme shows that, in given limitations in open information systems, the lower limit at which compression occurs as a result of construction of iterative structures, is the four-digit coding system. It suggests us to think that the fact that the codes constructed in the four-digit coding system will have a high value of the coefficient of compression. This result suggests that a four-letter alphabet coding, experimentally confirmed by the phenomenon of the genetic code. It is also shown its practical application value for the biological and natural systems, as well as - to explain, given the limitations of the phenomenon of short-term and long-term memory.Item Cross-platform native software development for mobile operating systems: (Android, IOS, Windows 8 RT)(2013) Schneider, Ch.; Hermanni, H.; Hänßgen, KlausIn this article you will find overview of most useful technologies for software engineering of mobile systems. The main problem is existence of group of mobile operation systems that has different paradigms and it is hard to develop software for all of them (Android, iOS, Windows 8RT). In this work we try to provide approach for software development for all mobile operation systems.Item General aspects of corporation management based on information systems(2013) Donadze, Mikheil; Khudzhadze, Nino; Didmanidze, DidariThe article discusses the problems in the integrated management of the contemporary business activities, and automatization of the activities in divided office-systems. The author gives the recommendations for the rational, management of the enterprise activities in the light of the modem information systems application.Item Optimized channel selection for multi-radio ІЕЕЕ 802.11 backbones(2013) Finsterbush, Mikhael; Khenshen, Klaus; Shmidt, PatrikThis paper presents the Simple Backbone Channel Allocation (SBCA) algorithm. It is used to optimize the channel assignment in IEEE 802.11 wireless backbone networks. We point to some specifics in channel assignment of backbones. It differs from channel assignment of single APs which is a node colouring problem of graph theory. Backbone channel assignment needs new strategies to cover all general conditions. We declare the SBCA algorithm and show its operation on an example. Our measurements show that it is very fast, correct in result andfinite.Item Preforecast time-series analysis of financial data(2013) Didmanidze, Ibraim; Kakhiani, HryhoriiThe main result is the conclusion that the possibility of pre-forecast analysis of financial time series in order to prepare them for use in the prediction using neural networks.Item Researching semistructured problems of multicriteria optimization using the software system(2013) Tryhub, Roman; Tryhub, Oleksandr; Horborukov, V.Develop the optimal decision support system for solving semistructured problems of multicriteria optimization, which can be used by individual or collegial body who take responsible decisions. Currently existing software tools, which solve this class problems are limited only by finding the best alternative, whereas the proposed system also (in addition to solving this problem) allows to develop instructions ("guidelines for actions ”) for any of losing alternatives so that the observance of them will guarantee the winning for this alternative.Item Simulators in educational process(2013) Didmanidze, Ibraim; Khudzhadze, Nino; Didmanidze, DidariIn article are considered as it is used training apparatus in educational process. Tributes examples of different training apparatus. Application of technologies of interactive training, virtual the laboratory is considered.Item Verifications of grouting models(2013) Demchuk, MykolaCalculation errors are estimated within the framework ofa model of the standard injection test. Such the test is conducted to verify simplifying assumptions of the model through comparison of model calculations with respective laboratory measurements. It is shown that the verification presented in this work as well as similar verifications presented in recent research, provides a small amount of information.Item Тhе use of opposing parties' reconciliation model for learning organization and knowledge management(2013) Didmanidze, Ibraim; Tkhilaishvili, RymaIt is used information model to manage and control using knowledge of the organization. This model is universal and it may be used for learning organization and knowledge management, thus for optimization of the learning process. First of all it is necessary to examine knowledge utilization “the channel” to build a model. So, statistically it must be learnt the process of acquiring knowledge. This is a statistical analysis of learning process for students to learn by observing the teacher, the student and the teacher s assessment of the quality of the used knowledge.
