In this article the results of analysis of special simply-supported plate by theory of plates of moderate thickness are presented. The special feature of this plate consists in specification of special boundary conditions on its edges which are different from usually specified boundary conditions. The uniformly distributed load is acting upon the plate. In this article the results of analysis by the finite element method are presented

Keywords: simply-supported plate, theory of thick plates, theory of plates of moderate thickness, Mindlin plate theory, Kirchhoff plate theory, bending moment, twisting moment, shear force, finite element method

A comparison was made between two methods for analyzing trends recorded by the scanner — EMD and EF. Informative components are given to build a forecast that can be used to change the controller in the system.

Dynamic norms for random and directed mutations in a genetic algorithm for solving the problem of placing elements in an orthonormal lattice have been developed. The principle of these norms is borrowed from the method of imitation annealing. The probability of using random mutations decreases in accordance with the annealing temperature, and the probability of directional mutations increases from iteration to iteration when approaching the optimum.

Keywords: genetic algorithm, the task of placing the elements, the annealing method, random mutations, directed deterministic mutations

The article proposes a structural-functional model of a data storage system based on solid-state drives, implementing deduplication technology to optimize the use of disk space. The concept is based on systems approach. The functioning model is presented in the form of interaction between the control subject (the system administrator) and the control object (the storage system). The system is exposed to external stream of requests from user applications over the Internet. The output parameters of the system include such performance indicators as storage capacity, storage time, storage cost, performance and reliability. The data storage system is presented in the form of four main integrated components, sequentially connected with each other: Network Service; deduplication system based on VDO technology; write management system, software RAID Control System; array of SSD drives. While the flow of requests passes through the system, the delay at each component is determined by the appropriate mathematical model. Such a structural and functional representation of the system allows applying the methods of statistical modeling and queuing theory to its analysis. The use of the proposed model will allow to design a data storage system of the given volume and service life with a minimum storage cost for a consumer with given performance and reliability indicators.

The article presents the results of the development of wooden building blocks that allow to saturate the room air with phytoncides of Siberian and other species of wood and plants. Shows the fundamental design of the blocks, the features of its production and processing. An example of the positive effect of essential oils on the reduction of bacterial air pollution is given. Buildings and structures of the proposed unit are quickly built without the use of specialized equipment. The construction and reconstruction of such a structure can be more effective in terms of both labor costs and terms of work, in comparison with traditional construction practices. Production of buildings from the offered blocks opens prospects of low-cost construction of low-rise constructions, both residential, and industrial use.

The poor quality of construction products is one of the main problems of the construction industry. A defect may occur at any stage of the product life cycle. The reputation of a company and its place in the market depends on how the company has established the process of management of non-conforming products and a dialogue with the consumer. In this article the method of management of quality ""8D"" which is capable to reveal not only the reasons of failures, but also to prevent their emergence further is considered, that is realizes one of the principles of quality management – continuous improvement. The article was published as part of the implementation of the program of the International Forum ""Victorious May 1945"".

Underground construction is gaining increasing relevance with the lack of free space on a construction site in dense urban areas. Geological conditions of the place at which it is planned to construct an object, make the task of erecting the underground part of the building is very difficult. However, the available construction technologies allow producing underground work in view of influencing factors. The availability and variety of ways to perform technological processes motivating the building organizations use sophisticated technologies develop. From what factors influenced the decision on the application of poluzakratoi technology is the subject of this article.
