THE STUDY OF AERODYNAMICS AND POWER CHARACTERISTICS OF SAVONIUS ROTOR

Posted in 2016, ENGINEERING, Issue December 2016 | 0 comments

Savonius type wind turbine is a vertical axis wind turbine, which has a high starting torque, a relatively low speed of operation and the ability to work in any direction of the wind. In this paper we studied the energеtic and the aerodynamic characteristics of the Savonius type wind turbine and focused on the main ways of their improving. The basic areas of researches on the improvement of the characteristics of Savonius rotors are the creation of mathematical models, the usage of hot air, the usage of water flows instead of the wind, as well as the changing the rotor design. The most efficient way of improvement the energy performance of the Savonius rotor is to add wind tunnels to the construction.

A NEW METHOD TO TRANSFORM SYSTEMS OF INEQUALITIES TO FIND THE INTERPOLATION OF MARTINGALE MEASURES

Posted in 2016, Issue December 2016, PHYSICS AND MATHEMATICS | 0 comments

For one-step model of stochastic basis a random process is considered where is a trivial -field, and is a -field generated by a countable number of atoms. It is assumed that takes four different values , where either (this process admits an infinite number of martingale measures). This article takes up such martingale measures that satisfy the weakened noncoincidence barycenter condition (WNBC), – condition that makes it possible to interpolate with such martingale measure incomplete market to completel with respect to arbitrary interpolating special Haar filtering.
A new method of proof of the existence of the interpolation martingale measures is presented in the article. It is based on the replacement of complex inequalities of the WNBC that contains various undefined subsets of the set of natural numbers, into more simple inequalities containing specific components of martingale measures. In this article we obtain sufficient conditions on market parameters, which ensure the existence of a martingale measure.
The obtained results can be the basis for the algorithm and software complex. The program based on the method will allow to apply special Haar interpolations method to the calculations on the arbitrage-free financial markets, which will greatly facilitate the choice of optimal strategies of investors in the financial markets.

INTERNATIONAL DISCUSSION ABOUT URBAN UNDERGROUND

Posted in 2016, ENGINEERING, Issue December 2016 | 0 comments

The article is based on the 15 World Conference ACUUS. The main world trends of using underground space for improvement quality the urban environment were described. We consider two fundamentally different approaches to the use of underground resources for the development of transport infrastructure of major cities. For example, Madrid is shown as vehicular traffic moves under the ground. The example of Moscow shows as it is possible to organize pedestrian streets lower than the level of the earth. The importance of the entry of Russia in a world scientific discussion about town-planning development of underground space is emphasized.

TECHNOLOGY OF CREATING SPICY SHASHLIK WITH THE HELP OF DRY HONEY POWDER

Posted in 2016, ENGINEERING, Issue December 2016 | 0 comments

The article discusses the possibility of using dry honey powder in the production of marinated meat products. Belgorod Region has adopted a program called “Beekeeping Development,” which was designed to promote the culture of bee products consumption, to increase the volume and extend the range of bee products, process them and sell. Thus, the production of these products with the help of dry honey powder is, in our opinion, a good solution. This article describes the issues related to the development of the recipe for “Spicy” shashlik with dry honey powder. The development took place at the Department of Raw Materials Technology and Products of Animal Origin of FSBEI of Higher Education Belgorod State Agricultural University. Dry honey powder was obtained by means of universal drying at the universal drying and crushing equipment YUVET 005. As a result, studies have found that perfect concentration of dry honey powder in semi-finished marinated product comprises 5%. The article presents the results of sensory studies of the samples of marinated semi-finished meat products. As a result, we determined the best sample of “Spicy” shashlik №3 for the consumer – it has a sufficient level of consumer properties, there is golden crust on its surface and it has a refined taste characterized by juiciness and tenderness.

A STUDY ON THE CAUSES OF THE DESTRUCTION OF THE ELEMENTS UNDER STRONG VEHICLES

Posted in 2016, ENGINEERING, Issue December 2016 | 0 comments

Investigated the causes of the destruction of parts of the vehicle suspension machine. based on the conducted analysis it was found that the trend of development of modern transport vehicles is aimed at reducing their weight and dimensions. As a result, most of the suspension components you receive with a minimal margin of safety. This fully considers the guide vanes of the suspension, including control arms. The simultaneous desire of manufacturers to improve the suspensions leads to the use of a fundamentally new structural solutions causing. Thus, manufacturers often keep the design a separate suspension components, durability and reliability have been confirmed by experience that operation. However, the change of schemes of loading of these parts can lead to a decrease in margin of strength and even destruction. When making structural changes to its suspension, even at half-strength preserving other characteristics of the traffic machine, you should perform the verification strength calculation of parts, which changes the load distribution.

A PRIORY COLLISION DETECTION ALGORITHM FOR 3-DOF HAPTIC RENDERING

Posted in 2016, Issue December 2016, MEDICINE | 0 comments

Simulation systems application is a modern way for students training in surgery. Most of the existing approaches require specific consumables that are destroyed during training. Thus, the training becomes quite expensive while not providing standardization of training process and making it difficult to rate the quality of skills trained. Exploitation of virtual reality provides much better education standardization capabilities while eliminating the need for consumables and making it possible to semiautomatic rating of training results. Collision detection is one of the key components of any haptic rendering algorithm. Most of the existing approaches to haptic rendering are based on a posteriori collision detection. An exploitation of a priory collision detection may drastically increase quality of haptic rendering. This paper describes a priory collision detection algorithm that may be effectively used by 3-DOF haptic rendering implementations.

THE STRUCTURE OF PRIMARY QUANTA OF ECONOMIC INTERACTION, THE PROPERTIES AS THE NEED OF THE MODERN ECONOMY

Posted in 2016, ECONOMICS, Issue December 2016 | 0 comments

In forecasting the development of the economies, the economy itself cannot predict its development in time and space. After the occurrence of any developing economy from the economists and start to explain to us why this happened. The reason is simple, the economy is defined, consists of a certain quantum of economic structures, a set of properties which define properties of the economy. With many of these quantum structures may predict the development of the economy, because the economic structure is invariant under any economy and a lot of them in time and space may be processed using computers, since they are homogeneous, even if a few economic structures. It is possible to apply the mathematical apparatus and, accordingly, to identify patterns of economic development.
