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.

THE CONCEPT AND IMPORTANCE OF THE HOTEL INDUSTRY IN MONTENEGRO

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

Hospitality is one of the most important and indispensable activities when it comes to attractive tourist destinations. High turnover of tourists, which brings enhancement and advancement of all the available resources of a tourist territory triggers and development processes in the accommodation industry and raises them to a higher level of quality and operations. The importance of the hotel industry for the economic and trade growth in the region and the entire country is an example of Montenegro. In recent years, as one of the most attractive destinations for tourists from all over the world has become a very common subject of observations of numerous authors from the scope of tourism and hospitality. In order to reflect the rapid growth of visitors to the rapid development and construction of the hotel industry, as well as the total social product, and what are the benefits, or deficiencies of such evolution are just some of the questions that require some answers.

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.
