REALIZATION OF THE SOFTWARE MODULE FOR A SYSTEM OF MANAGEMENT DECISIONS SUPPORT
DescriptionThe article describes realization of the software module called "Department work plan". This module is a part of the system of management decisions support. The primary function of the system is the process of generating documentation in higher education institutions. This software system and its additional software modules have been developed and tested at the Department of Computer Engineering of computer technologies and information security Institute of Southern Federal University (SFedU). The software module allows you to generate the work plan for the university’s subdivision, such as department. List of initial data for the work of software module is described in this article. The main algorithm distribution of department's workload for the academic year was described. The article describes the organization of work of the software module. The main stages of the generation of the work plan for the university subdivision were enumerated. The described process of generation of the work plan of the university subdivision was supplemented by illustrative material. The implemented software module has a convenient and functional user interface, which allows significantly facilitating the input and editing of data. The generated data can be exported in Microsoft Excel format. Considering the available opportunity to customize the module to fit the requirements of a particular user, it can be implemented in subdivisions of various universities

Description
The procedure of combined electrooptical processing which allows to disclose the reasonable energy and technological conditions of seeds’ treatment and to define the main factors which influence such seeds’ sowing qualities as: germinating power, germinating ability and length of sprouts is used in this article. Besides, the procedure allows conducting the research of efficiency evaluation of some rational parameters and conditions of treatment which influence their yield characteristics in field conditions. The research task was to obtain the data about the number of spring barley called “Ratnik” shoots and their productivity depending on the number of working volume converter’s lamps (1-6) and on the protectant’ norm percent (1-100). The experiments have been carried out and the data have been obtained for this purpose and the processing of these data has given the regression equation of the second order writing the process with the volumetric graphical interpretation. The rational parameter space of presowing treatment providing maximal germination and crop capacity of barley “Warrior” has been obtained on basis of the diagrams’ analysis. As the growth of germinating ability and crop capacity is observed when the number of working lamps is increased the double spreading at 6 working lamps should be recommended. The concentration of the protectant practically ceases to influent the crop capacity. According to the results of the research there has been drawn a conclusion that preliminary seeds treatment, for the purpose of plant diseases preventing, restrains the germination processes at the initial level. It happens in connection with conditions deterioration of moisture access to seeds which are covered with protectant film. Further processing of treated seeds by optical radiation promotes the growth of germinating ability and length of sprouts compensating negative effect of treatment

REGRESSIVE METHODS OF PROGNOSTICATION OF THE LOAD-GRAPH OF ELECTRICAL EQUIPMENT
DescriptionThe article discusses the use of regression methods of forecasting the deterministic time series on the example of the load curve. Forecasts of the load curve of electrical equipment are the demands of consumers and their security in EPS. All predictive tasks are based on prediction models. Electricity consumption is happening on an electronic level; storing electricity on an industrial scale is impossible, the consumption depends on many random factors. Therefore, generally, we use a combination of mathematical and heuristic models. This is the daily task of power systems and many technical, economic and commercial decisions on the management regimes depend on its solutions. Development of methods of forecasting of the energy consumption in the system of decision-making today is one of the priority directions in the Russian power industry. Therefore, the work associated with the development of methods and algorithms of forecasting of power consumption in the power sector is still relevant

Description
The article considers the mathematical task of calculating the transient flow of water in the regulation of concentrated releases of water discharges on stream flows in lower tails of spillway waterworks. An algorithm, analytical solutions based on hydraulic calculations of the process of propagation and transformation of long waves described by Saint-Venant equations are constituted. These equations are nonlinear and have no exact solutions. To obtain approximate solutions these equations are linearized. The efficiency of spillways depends on how accurately hydraulic processes characteristics are measured. Control and direct measurement of characteristics of hydraulic processes in natural conditions is difficult, which requires applying methods of mathematical modeling and simulation studies of transient processes, which are based on the algorithms of functioning of transient hydraulic processes control. Introduction of the developed method for hydraulic calculation of discharge releases to streams, diverting the water from water discharge structures, allows optimize idle and non-technological discharges of water from reservoirs. Considering the highly dynamic nature of the water flow in the lower tails of the dams at concentrated releases of water discharges from reservoirs, development of new methods of hydraulic calculation of extreme discharges and water depths at the critical sections of watercourses with transient regime of water flow is an important task

ADJUSTABLE BALLAST RESISTANCE FOR MOTORS WITH SLIP-RING MOTORS IN THE BREAK-STANDS
DescriptionThe article presents an overview of the run-in and testing of internal combustion engines, the analysis of break-brake- stands. We gave recommendations on expediency of the application of asynchronous motors with phase rotor winding on modern stands; we also considered its advantages over asynchronous motor with a short-circuited winding. As an alternative to the modern techniques, we have proposed a scheme of adjustable ballast circuit rotor using PWM modulation current. The process of adjustable ballast resistance and implementation of major break-regimes using the proposed device was also considered in this study
