DATA PROTECTION IN PUBLIC WI-FI NETWORKS
DescriptionWhile shopping, everyone is at risk of processing, use, and, as a consequence, dissemination of their personal data. We pay with a credit card, sometimes leaving our contact information, making the discount card and subscribing to various events, connecting and using a public Wi-Fi network in places where it is provided. Even our chaotic movement through the Mall is monitored, with the aim of creating logistics customer flow. Here, to help managers and executives of shopping centers, high technologies come. The companies already go beyond standard video recording devices and sensors invoice on the front door, letting your eyes for our phones. At the moment some companies are implementing monitoring smartphones using a Wi-Fi signal. This service will allow you to track the attendance of site, conversion of the people who pass by the object and its visitors, distribution of visitors for the facility, directions to consider regular and new visitors, the amount of time that visitors spend in the shopping center, but also to determine the hours of flows and downs of attendance during the day, in other words, to build a complete statistical report

QUANTITATIVE AND QUALITIVE ASSESSMENT OF SEEDS TRAUMATIZING WHILE USING MACHINES
DescriptionIncrease of gross grain collecting and minimization of cost of its production essentially depends on technologies and technical means, which are used while grain crops cultivation. At the same time the existing industrial seed farming and the grain’s production are assumed the multiple mechanical and thermomechanical impacts on grain from working tools of cars and units that leads to weevils’ traumatizing. Grain damage negatively affects its technological and fodder characteristics; seeds’ traumatizing causes the decrease in their sowing and fruitful features. It isn't possible to extract injured seeds from the pile because working tools damage the weevils itself and also there are small differences between damaged and undamaged weevils. It is possible to reduce grain traumatizing while machine preparation by reducing the quantity and extent of mechanical and thermomechanical impacts on weevils, by optimization of technological operations and by controlling the regimes and adjustments of working tools. The work of winnower machines M-819 KAS-10+SBVS-5 and AS- 10+ was researched while developing a technique of complex quantitative and quality standard of machines’ and tools’ influence on weevils’ traumatizing. It was ascertained that on different stages of weevils’ mechanical preparation it get different injuries in quantitative and qualitative expressions. It was offered to estimate the injuring ability of machines by the impact of seeds’ injures influence on its sowing features. Also there was a conception of traumatizing coefficient which includes either quantitative or qualitative debriefing influences of the traumatizing on grains features

THE NEED FOR THE USE OF RENEWABLE ENERGY SOURCES
DescriptionThe article reveals main reasons for developing tendencies to the using of new types of energy, which are limited supply of traditional fuels and environmental problems associated with its processing. It is shown that new forms of energy plays an important role in the energy supply of many countries of the world, and in the future they can become the main sources of energy to meet the growing needs of the global economy. We reveal main reasons of the increasing interest in renewable energy, and we show the obvious prospects of their use, due to two factors. First, according to experts, the global reserves of traditional fuels are limited, and secondly, this was evidenced by the investments of leading countries in this promising industry. The article lists reasons for the need for the use of renewable energy sources in Russia. Increased consumption of natural resources has become a real threat to the security of the life of human society. The basis of solving modern social and environmental problems is a transition to a regulated process of safe use of natural energy potential to meet the vital needs of people not only in the coming decades, but in the long run. It is concluded, that the determining condition for the development of the human civilization at present and in the future would be the level of natural resources which ensures the needs of the population without making harm to the environment

TO THE NONPARAMETRIC IDENTIFICATION OF TECHNOLOGICAL PROCESS OF SEQUENCE OBJECTS
DescriptionThe task of nonparametric identification of sequence objects with discrete-continuous nature of the process under nonparametric uncertainty, i.e. in conditions where a priori information is not sufficient for an informed choice of a model structure up to parameters is considered. Among series-connected objects, there can be objects both dynamic and instantaneous ones with a lag. This kind of technological chains is common in various industries, particularly in metal, power, oil refining, etc. in solving this problem were used methods of nonparametric identification theory, mathematical statistics and statistical modeling. The theory of nonparametric systems is based on local approximation methods, in particular algorithms for nonparametric estimation of different kind of dependency from observation of input-output variables of the object. The article presents a nonparametric model for the group of spinning objects with delay. In the work we show in detail the results of numerical studies showing that the use of nonparametric algorithms allows predicting process performance with sufficient accuracy

Description
One of the key areas of interdisciplinary research is to ensure public safety. In order to solve a number of problems within this area we can effectively use information technology and, in particular, an automated pattern recognition technology and identification of objects on digital images. There are addition problems in objects identifying process besides eliminating the influence of ambient light, angle, items of clothing and headgear. To ensure the applicability of the recognition approach to public security issues it must meet requirements of the high processing speed, the replenishment capabilities onthe-fly list of known images, and the low computational complexity of algorithms. The article deals with the main approaches to the recognition and identification of objects on digital images based on statistical approaches, as well as neural network models. We have allocate their basic features and principles, provided a brief description of each method. Consideration has been made in terms of the application for the problems of public safety, in which there is importance of the speed of the identification of the object, the ability of quickly learning for the system to accept new images and simultaneously process a plurality of input images. The analysis of the existing approaches has shown that none of them satisfy at least one or several needs, which are defined by domain problems of public safety

ABOUT DETERMINATION OF COORDINATES OF GEODETIC AREAS BY LINEAR SERIFS
DescriptionProblem of geodetic area coordinate determination for concentration of planned nets, binding and other works, by means of execution only linear serifs is considered in the given work. Way of determination of coordinates of two areas with the help of linear serifs was offered. Mathematical processing of received results and numeric example of its realization were casted.
