Abstract: Mechanisms to collect and convert the format of presentation of the initial information are essential in the functional structure of management systems for information security incidents. Therefore, the paper discusses the development of a module for events translation, which provides merging registration events into one point. And it is also important to have the ability to implement transfer of raw data from single sensors into the consolidated database system of correlation. This requires development of a mechanism of data aggregation with further normalization and prioritization which provides source data compression for subsequent decision making on the presence / absence of information security incident over the current period. The authors carried out the development of the mathematical apparatus for translation events module for perspective management systems for information security incidents, which provides merging registration events from many sources into one point. In this paper the authors propose a mechanism for gathering and converting the format of presentation of the initial information, including: a procedure for data converting before transporting by assigning alpha or numeric identifier to fields of registration logs line by line and splitting these identifiers into groups; procedures of categorization and prioritization;  algorithm for aggregating data about events, based on the calculation of the sample coefficient of correlation between signs of elementary events.

Abstract: The author studies the early stages of the software life cycle on the quality of which the quality of the result of software development essentially depends. An analysis of the experience of the practical application of the widely used waterfall (cascade), iterative and incremental models of software life cycle showed that they do not fully meet the needs of the practices. However, there is a possibility of the synthesis of a new model of the life cycle of software that combines all of these three models. The research methodology is based on the models of the software life cycle, structured systems analysis, software engineering, and information and logical modeling. The main conclusions of the study lies in the model of the software life cycle (for the stage of its development), presented in notation UML-diagrams, which consists of the stages of initiation of development, setting the increment, execution of the increment and completion of the development. Practical implementation of the developed model provides a reduction in the time required for software development and preparing the necessary project documentation.

Abstract: In this paper a problem of network planning and management with a random duration of individual operations is considered. The subject of the study is the law of distribution of the random variable which describes duration of the project. The aim is to estimate such law. The urgency of this problem is related to the need to improve the accuracy of the known existing assessments which do not take into account the specifics of the distribution law of separate works determining the project. The main difficulty of the practical solution of this problem is the need to calculate the multiple definite integral, wherein the number of individual integrals not known in advance and determined by the number of works that make up the critical path of the project. As a result, the numerical method based on recursion is proposed, which allows to numerically estimate the desired distribution law. Scientific novelty of the results is in obtaining estimates of the distribution law of the duration of the project that improves positional accuracy over the existing analogues. Without loss of generality developed a recursive algorithm can be used for a wide class of problems in which the unknown distribution of the sum of random variables with known distributions of the individual terms.

Abstract: The object of research is a new way of defining and visualizing a photorealistic terrain. The method to render a terrain as easily as a texture is proposed. A terrain model is coded as differential height map, i.e. the carrier surface is defined by algebraic means and only deviation from this basic surface is stored in the each node. Such a modeling method simplifies creation of smooth detail levels and shading. The data of height grid is not a subject to geometry transformations as the triangle vertices are. The geometry transformations are only required for the carrier surface. During the recursive voxel subdivision on each level, we project the centers of the voxels onto basic plane. The computed coordinates, as well as in the case of ordinary RGB texture map, will define address in the so called "altitude map" or "shape texture". The altitude corresponding to this address and a level of details is calculated, and are used to modify coefficients of the base plane equation. As a result will be obtained a surface modulated with the values from the altitude map. Visualization in real time on graphical accelerators is implemented. The method is based on the analytic geometry in space, differential geometry and vector algebra, interpolation theory and matrix theory, based on mathematical modeling and computer science. The main conclusions of the study are: the ability to generate the terrain using the same mechanism as for the texture color to display the terrain and changing levels of detail. The image interpolation is used for filtering heights dynamically similar to color texture. In comparison with the known methods the proposed method computation time substantially does not dependent on the resolution of the height map when generating a terrain.

Abstract: The paper presents a study of procedures of automated monitoring and regulation of the safety of aircraft, as well as procedures for the automated control of the changes in the air-operated transport system. Analysis of the dynamics of the safety of aircraft is required to obtain an objective assessment of the effectiveness of corporate safety management system and its planned development, that is a requirement of the standards of the International Air Transport Association and recommended practice of ICAO. A detection of unacceptable values in the current or forecasted level of the safety reflects the state of aviation transport system, characterized by a potentially high risk that requires a rapid response from analysis of aviation incidents and prerequisites to them to determining the cause of unacceptable changes with subsequent regulations in safety management. To solve this problem author uses results of regular monthly monitoring of the current level of safety in the airline statistics of aviation events registered in the safety management system of the company, which was then processed using the theory of probability and mathematical statistics. The novelty of the research is in created software for automated predictive safety monitoring of airlines using statistical detection of potentially dangerous changes in the level of safety, based on the analysis of retrospective information obtained as a result of monitoring of the safety of the flight, taking into account the requirements of international standards in the field of civil aviation.
