NEURAL NETWORK PREDICTION MODULE FOR ELECTRICITY CONSUMPTION
DescriptionIn this work, we consider the design and development of neural network software module for prediction of electricity consumption in the system of support of decision-making power control. Two prediction models support the software module: regression model and neural network model, based on multilayer perceptron. Software development to predict power 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 surely relevant

SOME ASPECTS OF REDUCING FRUIT DAMAGE DURING HARVESTING AND TRANSPORT OPERATIONS
DescriptionFruit harvesting is the final and decisive operation in the general work plan for growing fruit, which largely determines the qualitative and quantitative indicators of production and economy of industry in general. Increasing productivity by improving the safety of fruits and vegetables is a priority and not an easy task. For example, the use of cleaning technologies with the use of machinery for harvesting of apples by shaking can significantly reduce the time of gathering fruit compared to hand harvesting. This technology may be applicable, if the fruit is grown for the manufacture of juices, jams, etc. Currently, in several European countries and in the USA, they widely use fruit harvesting platforms and machines. The leader in the production of fruit harvesting platforms is Italy. To reduce the damage to fruit in agriculture, the analysis of the traumatic factors is of great importance, with the analysis of available machines and their subsequent modernization with the aim of improving the reliability and quality of harvesting and transport process, taking into account of the algorithm for solving these problems, the creation of new varieties of fruits and vegetables suitable for machine processing, strict compliance with deadlines and agronomic requirements for the performed technological operations, taking into account the savings of energy and resources when using mobile technology. In addition to the modernization of the machines for efficient operation, it is necessary to improve also the scheme of planting of gardens and methods of cultivation, transfer horticulture to intensive way of development

NECESSARY CONDITIONS FOR THE DEVELOPMENT OF A CONTROL LIGHTING SYSTEM
DescriptionAutomated lighting control system designed for use in public buildings; they perform actions typical for this kind of products. Accurate maintenance of artificial light in the room at the set level. This is achieved by having a lighting control system with a photocell inside the room and controlling the lighting system illumination. Even only one this function allows you to save energy due to the cutoff of the so-called "excess light". Calculating natural light in the room. Despite having the vast majority of premises with natural lighting in the daytime, the power of the lighting system is calculated excluding. If you maintain illumination created jointly by a lighting system and natural light, at a predetermined level, it is possible to further reduce the power of the lighting system at each moment of time. At certain times of the year and hours of the day, perhaps it is enough to use just natural light. This function can be carried out by the same solar cell as in the previous case, provided that it tracks the full (natural + artificial) illumination. In this case, the energy savings can be at 20 - 40% level

NONPARAMETRIC ADAPTIVE DUAL CIRCUIT CONTROL OF DYNAMIC PROCESSES UNDER PARTIAL UNCERTAINTY
DescriptionThe article considers the tasks of nonparametric dual control of dynamic objects with discrete-continuous nature of the process is considered. In this case, the only value of memory depth of dynamic processes is known, but the parametric structure of the model is partially unknown. The nonparametric algorithms of adaptive dual control for external control loop were offered. The proposed loop of control is designed for systems, which include in technological scheme internal control loop, specifically a standard controller. In solving this problem, the methods of nonparametric identification theory, control theory, the theory of adaptive systems, mathematical statistics and statistical modeling are used. The theoretical information of the non-parametric algorithms of dual adaptive control under conditions of incomplete information of the process is produced. The essential difference between the dual control algorithms from the standard is that the nonparametric control unit performs two functions: research and control of the process of active accumulation of information. The computational experiments show that the introduction of the proposed scheme significantly improves the quality of control, and the existing control system in operating controls are maintained

NONSTATIONARY CATALYTIC SYSTEMS FOR THE PROCESSES OF BIOGAS PRODUCTION
DescriptionThe new circuit-design solutions of catalytic systems for the processes of producing biogas from organic waste are proposed. They are based on the analysis of existent tech. solutions. The interaction features of the flow of reactants to the catalytic filler in the proposed catalytic systems allow us to intensify the process of reaction, as well as to optimize the design features of catalytic systems based on the technological process

Description
The idea of systemic generalization of mathematics was substantiated by the author and the first step on its realization was done: variant of systemic information theory was proposed. There was done an attempt to do the second step in the same way: one of the possible approaches to the systemic generalization of mathematic understanding of set on the conceptual level, namely the approach, based on systemic information theory. It is supposed that this approach can become the basic one for systemic generalization of set theory and creation of mathematic theory of systems.
