Renewable Energy: Prospects for Energy Development Correction in Russia

Abstract: The concept of sustainable development has identified the vector of technological development of the energy sector: support for renewable energy sources (RES) along with a reduction in the cost of electricity produced by them to the values comparable to traditional energy has led to the transformation of all parts of the seamless technological process of energy production and consumption. In the next decade in Russia, correction of energy development from the existing object system towards integration of consumers and energy producers by providing the ability to adjust power consumption to the generation schedule and the development of distributed cogeneration using the established heat consumption is a more effective way to reduce the negative human-induced impact in contrast to building of wind or solar power plants. Coverage of the peak load with cycling units in the mode of combined heat and power generation, having the ability to work according to the schedule of electric rather than thermal loads, as well as increasing the flexibility of power consumption, are the ways to increase the power utilization rate of traditional energy and reduce specific fuel consumption, and, in the future, to minimize costs for connecting stochastic renewable energy generation into the network.

Minkowski sum of a parallelotope and a segment

Abstract: Not every parallelotope is such that the Minkowski sum of with a segment of the straight line along a vector is a parallelotope. If is a parallelotope, then is said to be free along . The parallelotope is not always a Voronoi polytope. The well-known Voronoi conjecture states that every parallelotope is affinely equivalent to a Voronoi polytope. An attempt is made to prove Voronoi's conjecture for . For that a class of canonically defined parallelotopes that are free along is introduced. It is proved that is affinely equivalent to a Voronoi polytope if and only if is a direct sum of parallelotopes of class .This simple case of the proof of Voronoi's conjecture is an instructive example for understanding the general case.

Towards a Semantic Segment of a Research e-Infrastructure: Necessary Information Objects, Tools and Services

Abstract: Basically semantic linkage technique is used to specify in computer readable form known facts or relationships that definitely exist between information objects like people, organizations, research results, etc. Recently developers also started using it to visualize scientists’ opinions or scientific hypotheses (e.g. inference/deduction, impact/usage, theoretical hierarchy, etc.) about relationships between research objects. Based on CERIF Link entity and the Semantic Layer and assuming that scientists typically re-use research objects by making relationships between them we propose a sketch of a research e-infrastructure semantic segment, which allow scientists unlimited re-use of research information systems (RIS) content. After some development a semantic linkage technique provides scientists with tools and services for semantic linking of any pair of research objects, which metadata are available within content of any RIS. This application also allows scientists a decentralized development of semantic vocabularies that guarantee a covering by this technique any new types of relationships. In the paper we discuss information objects, tools and services which are necessary for proper functioning of proposed segment of the research e-infrastructure. We also discuss a “quality control” topic which in this context is very important.

СТАТИСТИЧЕСКИЕ И ТЕОРЕТИЧЕСКИЕ МОДЕЛИ ЗАВИСИМОСТИ СТОИМОСТИ МАШИН ОТ ВОЗРАСТА (Statistical and Theoretical Models of the Effect of Age on the Market Value of Machinery and Equipment Items)

Abstract: Russian Abstract: При оценке подержанных машин и оборудования используются зависимости их рыночной стоимости от возраста. Обрабатывая рыночные данных о ценах реальных сделок с такими машинами (или о ценах их предложения), можно построить соответствующую статистическую зависимость. В то же время можно построить детерминированную модель той же зависимости, основываясь на общих принципах стоимостной оценки. Оказывается, что полученный результат не согласуется с данными рынка. Разрешить этот парадокс оказывается возможным, учитывая вероятностный характер процесса использования машин. Построенная вероятностная модель позволила получить простую формулу для математического ожидания рыночной стоимости машин, доживших определенного возраста.Казалось бы, техническое состояние машины (а, стало быть, и ее стоимость) должно зависеть не только от возраста, но и от ее наработки. Однако проведенный анализ показал слабое влияние наработки на стоимость машин.English Abstract: Evaluation of second-hand machinery and equipment items requires information on the dependence of their market value on the age. Using market price data for these assets, you can get relevant statistical dependence. At the same time we can build a deterministic model of the same dependence based on common valuation principles. It turns out that the result is not consistent with the market data. We can resolve this paradox taking into account the stochasticity of the process of machinery and equipment items use. Built stochastic model allowed us to obtain a simple formula for the mean of the market value of equipment items lived to a certain age.It would seem that the technical condition of the equipment item (and hence its value) should depend not only on its age but also on its operation time. However the analysis showed that operating time of equipment item has little effect on its market value.
