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

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

ABOUT THE MOTION OF THE VIBROLIQUEFIED SEPARATED LAYER OF GRAIN ON THE FLAT SIEVE OF FINITE WIDTH
DescriptionThe aim of the research is analytical determination of the middle speed of the corn seeds on the flat vibrating sieve of finite width. The object of the study is the process of sorting of seeds of corn on the flat vibrating sieve. The mathematical modeling of the motion of the separated layer of the cereal mixture on the sieve is conditioned by the necessity of intensification of division of grain-growing materials on a flat sieve. Despite the significant progress in the development of mathematical models of the motion of a mixture on vibrated sieve, their further refinement remains an actual task. In particular, in calculation practice, theory in which the width of the flat sieve is considered infinite is used, i.e. the impact on the process of the moving frame of the sieve bed is not taken into account. In connection with absence of estimations of the error brought in by this assumption, the necessity to develop a theory of the movement of the mixture on a sieve of the finite width appeared. For the analysis, the following assumptions were accepted: first, the corn seeds were considered as balls of different diameter, second – the layer of grain on a sieve was considered as heterogeneous viscid liquid. Based on undertaken study it is set that most rational for the achievement of the put aim is application of method of Bubnov-Galerkin. As a result of undertaken research analytical dependences are received for the calculation of flowrate of grain mixture on the vibrational sieve of the final width taking into account separation of the mixture into factions

ABOUT THE APPROACH TO REALIZATION OF MANAGEMENT SUBSYSTEM OF SMARTHOUSE
DescriptionThis article describes the purpose of SmartHouse systems, noting their advantages and disadvantages. We have identified sustainable trends in the implementation of such systems in the life of modern people, and there has been a substantiation of the need for their development. The article provides a detailed description of a SmartHouse system and the generalized structure of the system. Existing approaches to management systems implementation SmartHouse was consider. The subsystem of lighting control was considered as an example. The structural diagram of this subsystem was developed. We have justified the choice of technical devices, hardware and software subsystem of lighting control; we have also given their description. As a subsystem device we use Bluetooth module HC-05/06, four channel relay module to connect to Arduino, Arduino Mega 2560 plate. We briefly describe the process of programming the Arduino Mega plate. The necessity of remote access subsystems was substantiated. We have reviewed existing standards and technologies for solving such problems and proposed the implementation of remote access subsystem via a mobile communication system using the Bluetooth standard. The developed mobile application that allows you to control devices on the example of the lighting subsystem was described. We have performed testing of the model of a subsystem of lighting control and the developed software. The proposal for the development of this work was given. The further development of the subsystems of the SmartHouse and realizing of remote access system through the Internet were offered
