Abstract: Protein secondary structure prediction has been and will continue to be a rich research field. This is because the protein structure and shape directly affect protein behavior. Moreover, the number of known secondary and tertiary structures versus primary structures is relatively small. Although the secondary prediction started in the seventies but it has been together with the tertiary structure prediction a topic that is always under research. This paper presents a technical study on recent methods used for secondary structure prediction using amino acid sequence. The methods are studied along with their accuracy levels. The most known methods like Neural Networks and Support Vector Machines are shown and other techniques as well. The paper shows different approaches for predicting the protein structures that showed different accuracies that ranged from 50% to over than 90%. The most commonly used technique is Neural Networks. However, Case Based Reasoning and Mixed Integer Linear Optimization showed the best accuracy among the machine learning techniques and provided accuracy of approximately 83%.

Abstract: The current development of society requires the use of modern information technologies of business administration, regardless the field of activity. For automation and informatization an enterprise requires the introduction of innovative technologies, including technologies for knowledge management. To ensure the integration of modern information technology corresponding to the noospheric stage of scientific development organizations require highly qualified analysts for consolidated information (business intelligence analysts, information analysts, knowledge managers). The Social Informatics Department of the Kharkiv National University of Radio Electronics is engaged in the training of such specialists, its workers developed a standard for the preparation of consolidated information analysts in Ukraine. This standard is largely in line with the preparation of Competitive Intelligence Professionals (Competitive Intelligence)1, 2. Special difficulties in the training of consolidated information analysts in a lack of teaching hours are related to the need of development of a special kind of systematic analytical and creative thinking, as well as the ability to perceive and implement modern world standards of information and organizational culture. The training program is formed in a manner to develop thinking and understanding of the relevance, necessity and features of work with knowledge at the graduates from various universities and bachelor systems. An important role in this process belongs to the integration of educational and scientific process at the department that allows us to prepare highly qualified specialists in a short time, but the main feature is the use of training in the preparation of a noospheric system methodology - systemology and modern systemological method – the systemological classification analysis 3. The article deals with the relevance of the training and development of the specialty through the use of modern tools of knowledge management, some aspects of the training of consolidated information analysts, methods and tools to improve the quality of their education in terms of reducing academic load and reduce the direct interaction between teachers and students.

Keywords: Knowledge management, consolidated information analyst, systemological classification analysis, information technology, classification, social network on the Internet, model, e-learning, UML diagrams, learning organization, software testing, business process analysis and modeling requirements.

Abstract: This article presents a model of the money circulation in Bulgaria, based on the data about coins, excavated in Bulgaria and published in the Proceedings of the (Bulgarian) Archaeological Society (PAS) during the period 1910-1920 and in the Proceedings of the (Bulgarian) Archaeological Institute (PAI) during the period 1921-1959. We construct the Chronological Distribution of these coins and its graph using computer technology (the package MS Excel in our case). The studied material consists of over 280000 coins, which in our view is large enough to give an adequate picture in a first approximation of the chronological distribution of all coins excavated in the Bulgarian lands during the period 1910-1959. We think that it also gives a plausible picture of the monetary circulation in the eastern part of the Balkan Peninsula during the different historical periods. We discuss some considerable anomalies of the obtained chronological distribution. The results of the analysis juxtaposed with a peculiarity of the Chronological Distribution of Byzantine coins noticed by A. Kazhdan leads us to the hypothesis that there are probably certain mistakes in the accepted dating of some ancient coins.

Abstract: The rules for preparing the manuscripts for the International Journals (IJ) and International Book Series (IBS) of the ITHEA International Scientific Society (ITHEA ISS) are outlined. We study mobile communication of networks, the ad hoc networks, Ad hoc networks are complex distributed systems that consist of wireless mobile or static nodes that can freely and dynamically self-organize. The parameter of the queuing models depends on the node mobility pattern. The main finding is that the expected relay buffer size depends on the expectation and the variance of the nodes contact time. Such analysis is done for the three dimensional random walks models over a circle; expected relay buffer size depends on the expectation and the variance of the nodes contact time. First model-The source node transmits a packet only once (either to the relay or to the destination node). Thus, the source node does not keep a copy of the packet once it has been sent. When the source node transmits a packet to the destination node (when their locations permit such a transmission), the source node transmits packets that it has not transmitted before. The source node has always data to send to the destination node. This is a standard assumption, also made in GMPS04, GT02, GK00, because we are interested in the maximum relay throughput of the relay node. This shows: the first relay node performs a Random walk and the source and destination are fixed, second the source, the destination, and the relay node move inside a square according to the RD model. Second model-The relay node is moving according to a symmetric random walk (RW) on a circle of 4R + 2w steps. Third model - Three nodes: a source a destination and a relay source, nodes are moving a cording a symmetrical Random Walk over a circle.

Abstract: Changes of professional environment, caused by introduction of new technologies and techniques, create a necessity in continuous education and development of professional competences. In these conditions, managers and other company employees face the choice of methods and tools of personnel training. A business game is one of the most productive tools of business-education. This paper elaborates the ideas embodied previously, which considered the conceptual approach to a toolkit creation for active training techniques in a form of competence-based business game studio. Competence-based business game studio is an ergatic system for development of professional competences, which are required to ensure organization’s business processes. Business game control is performed with the help of automate module, which executes the interpretation of expressions in algorithm logical scheme language. Unified business process is the input data for automate model construction. Unified business process is acquired from the information about company’s real business processes, represented in poorly formalized ways. Unified business process transforms into unified training business process, which includes possible business game trainee actions and information about input, output, administrative data and business process operation execution mechanism. The next step to automate model is the construction of scenario graph, which represents a more formalized description of unified training business process. Next, the administrating algorithm of the business game in algorithm logical scheme language is built. The paper considers the algorithms of transition between models that allow automating the process of acquiring algorithm logical scheme in order to implement the business games scenario.

In our previous work we modelled these competencies using topic models, but in order to have a more effective understanding of the market, we have to take into account the dynamics of the system as well. Here we propose using dynamic topic modelling as a means of analysing the job market for competencies and qualifications stemming from our previous research.

Abstract: Shot boundary detection is main step in video management systems like browsing and indexing. In this paper, we shortly describe an earlier proposed shot detection algorithm based on the structural properties of video frames. Two mathematical models for decision making, i.e. for similarity threshold determination are proposed and compared. The first model allows determination of threshold in case of using mean-square deviation for frames similarity and when the image pixel is assumed to be normal distributed random variable. The second model is based on using the structural similarity measure based on Weibull model for image gradient magnitude distribution. Global and adaptive approaches are considered for frames similarity threshold determination. Results of experiments to detect real video shots are given. It is shown that adaptive threshold determination method generally gives more acceptable results than global threshold determination method. At the same time the 2 W based threshold determination approach gives more accurate results than PSNR based approach, therewith corresponds to HVS perception.

Abstract: Method of domain models designing is proposed in this paper. Domain models are represented as class diagrams. Initial information for domain models designing contains both analytical representation of domain data streams and domain entities. Domain data streams are defined using collaboration diagram. Analytical representation of domain data streams as a subset of Cartesian product of the following sets: objects and messages are proposed. Also an approach of decomposition collaboration diagram into fragments for defining data streams is represented. Rules of defining relations between classes of domain model by means of analysis both analytical and graphical representation of domain data streams are formulated. Both description of domain entities and interconnections between them are represented in terms of algebra describing software static models. Proposed method involves an iterative approach for domain model designing. Firstly it is necessary to obtain information about class diagram constituents. Then information about methods of classes is complimented using analytical representation of domain data streams. Using both analytical representation of domain data streams and analytical description of entities relations between class diagram constituents are defined and clarified. An example of designing domain model for domain “designing cutting schemas for leather goods details” is represented. Also information about interconnections of domain entities and domain processes is represented.

Abstract: Relationships and communication between doctors and patients is a very important problem in medicine. Analysis of possible interrelated directions of development and application of communicators in emergency and family medicine was performed. According to the first direction the IT communicators are intended for supporting alternative communication with the people lost temporarily or permanently possibility to speak. According to the second direction proposed communicators have databases included detailed information about types of diseases and traumas, and by results of analysis of injured person symptoms or feelings the software subsystem generates some variants of possible diseases or traumas diagnosis. It is proposed to apply special hardware-software means, particularly IT communicators to simplify the communication of doctors with patients (particularly with voice limitation) and increase treatment efficiency beginning from the first contact. Proposed IT communicators are used in family and emergency medicine for supporting first contact of doctors with patients (with voice limitation) and getting information about patient state, for example, during the preliminary examination of patients. Application of proposed modern computer devices and information technologies in medicine makes it possible to reduce a number of cognitive problems, increase the efficiency of the first contact of patients with doctors, quickly give a diagnosis and correctly select methods of treatment.
