Current protection relay are the main for protection of electric networks of all levels of tension. For realization of current protection various information signs which are formed proceeding from objectives of ensuring reliable operation of current relays in transitional modes and at information distortions are used. Results of the analysis of work of current protection of terminals SEPAM 1000+ and REF 615 in the conditions of a strong overload of transformers of current for the purpose of identification of information sign of terminals operation are presented. It is established that in emergency operation when currents reach great values and sate measuring transformers of current, the accuracy of terminals operation considerably falls. The best results are yielded by algorithm of determination of size of primary current direct measurement of amplitude of an entrance signal. At saturation of the measuring transformer of current over 40% the error of such method significantly increases.

Improving transport service production activities of agro-industries

T.V. Konovalova, S.L. Nadiryan, O.I. Meleshchenko

This article deals with the problems of construction of transport – logistic system of the enterprise of agro-industrial complex. On the basis of the conducted research the main logistics principles and conditions that allow a modern enterprise to maintain a stable position in the market. Agricultural and transport complexes are closely related as organizationally and economically as part of a regional logistic system. Production processes in the agricultural enterprises are characterized by isolation of economic processes, although integrated into the regional economy, often as a backbone at the meso-level. The current economic study mainly aims at studying logistics systems at the macro- and meso-levels. However, the development of the regional economy is impossible without the effective functioning of specific agro-industrial enterprises. One of the significant factors affecting the company’s production activities of agro-industrial complex, is transport. Transport and logistics system of any enterprise, including agricultural not be considered in isolation from the General economic processes (external factors)that define the vectors of input and output. These not only affect the stability of the system, but also largely determine the model of internal logistics operations.

Keywords: transport industry, agriculture, transport and logistics system, macro-level, meso-level, micro-level, material flows, optimality criteria.

The use of network architecture of information systems in the car

A.A. Izyumsky, S.L. Nadiryan, I.S. Senin

Peculiarities of the development of the information system of a modern car are considered. Requirements to the information systems of modern vehicles and their capacity to grow following the appearance of a new complex applications – for example, security systems and systems of processing of multimedia information. The existing network of control of the vehicle, such as LIN, CAN and FlexRay, cannot cover the increasing demands on bandwidth and scalability needed for different systems, driver assistance. New networking technologies should learn as much as possible from domestic and other non-automobile areas, but taking into account the specific requirements of avtopiloti. The use of Ethernet in a vehicle means a paradigm shift in developing the next generation of automotive computer networks: linking different network domains, transporting various types of data (control signals, streaming and others) and the implementation of stricter requirements for reliability in harsh conditions for the extended temperature range and electromagnetic compatibility. The communications network will be hierarchically organized with domain controllers that are connected via the Ethernet backbone. Subnet below domain controllers can also be based Ethernet switches between levels. This structure provides a scalable solution, because each port on the switch in the General case can be implemented as a 10-Mbps, 100-Mbps and 1 Gbps without any changes in the higher levels of the Protocol. The novelty of the approach lies in how the message is sent across domain boundaries to the destination. In modern networks and interconnection interfaces implementation of this function is the IP routing using switches and routers, as suggested for backbone networks. The advantage is the complete independence of the IP routing from the realization that allows you to create a single solution for the road network. Also, the idea of IP makes it easy to connect the vehicle to the Internet.

On the need for unification of the disciplinary measures of self-regulatory organizations cadastral engineers used against its members

A.V. Osennyaya, A.M. Seredin, E.D. Osennyaya, V.L. Hortsev

Unlike justified self-regulatory organizations cadastral engineers from other forms of non-profit organizations – the establishment of specialized bodies responsible for supervising compliance with the requirements of these standards and regulations, as well as the bodies having authority to impose disciplinary action in case of violations. Considered a list of disciplinary action by the Federal Law of 1 December 2007. N 315-FZ “On the self-regulatory organizations”, the decision on the application of which is entitled to take a specialized body of the self-regulatory organization. Analyzed internal documents of self-regulatory organizations cadastral engineers, bringing revealed differences in the penalties disciplinary self-regulatory organizations to their members, and in most cases, lack of fixed bases of these measures. The prospects for the introduction of compulsory membership of cadastral engineers in the self-regulatory organizations, and the consequences of unfair SROs perform control functions in these conditions. Proved the need to harmonize the requirements for disciplinary procedures applicable self-regulatory organizations cadastral engineers. Should deal with this issue a national association of self-regulatory organizations cadastral engineers – NP “National Chamber of Cadastral Engineers”. However, the association developed disciplinary standards and regulations should not be imposed SRO, but primarily to get federal, that is mandatory for all self-regulatory organizations in the field of cadastral activities. Then it will not further burdening the participating organizations, and the actual ordering process.

Neural network classification and discriminant analysis of a regulatory and adaptive possibilities of the human body level

S.V. Usatikov, T.V. Shkirya

In order to improve the existing incremental principle of determining the cardio-respiratory synchronism (CRS) phenomenon range, statistical discriminative analysis and neural network analysis of regulatory and adaptive status of the human body (RAS) quantitative specification system data have been conducted. The main objective is to obtain projected RAS level on the basis of its least-consuming measurements and by fixing the parameters, with preliminary identification of these parameters. Calculations have been performed using Statistica pack v. 10 (StatSoft Inc., USA). The following factors-arguments have been examined: the Minimum limit of CRS, Duration of evolution synchronization at the minimum border, Initial heart rate, Initial respiratory rate, Duration of recovery at minimum border, as well as the Kerdo index. As the basis of the forecast the following categories have been taken into account: age, height, weight, sex and phase of the menstrual cycle (for women), the values of diastolic and systolic blood pressure. Linear and quadratic regression models, linear discriminant analysis and neural network techniques (NN) – multilayer perceptron and network of radial basis function type have been analyzed. Neural network regression and classification have shown the best accuracy. NN-classification of PAS level can be made on these grounds with a probability greater than 70%; with a probability more than 90% error is less than one level.
