Issue 09 July-August-September 2016 The Creation Of Fluid And Gas Mechanics Basis In The Micro-Cracked Channel R.S. Gurbanov, M.A. Mammadova, A.A. Hajiyev There are experimental investigations of the fluids flow in the small-sized channels, the hydraulic resistances results of which are more than the estimated ones according to theoretical formulas and different supposed explanations without the quantitative evolution have been given in the reference. Taking into consideration this situation in the mechanics we were conducted the experiments in special developed unit with different fluids: water, viscous and anomalous oils. The results of the numerous experimental investigations for deter- mining new effect of fluid mechanics in the micro-cracked channels have been given in this work. Firstly the experimental-estimated methodology in the “micro-crack fluid” system has been proposed and realized for the quantita- tive estimation of the hydraulic resistances. This approach allows to conduct hydrodynamic engineering estimations for fluids flow in the fractured-porous medium, in the mechanical engineering, in the lubrication systems of instrument engineering and also for solutions of the sealing problems in different branches of industry and medicine. Multi-Criterial Estimation Of The Level Of Corrosion Damage Of The Gas-Pipeline Areas In The Ambiguous Expert Opinions S.A. Aghammadova The linguistic model has-been developed for the estimation of the corrosion damage level of the gas-pipeline areas in the optimistic and the pessimistic expert opinions of the influencing factors. For solving of the given task generalization of the method of multi-criterial choice of the best alternative in the case of rules of fuzzy productions has been chosen, antecedents and consequents of which have been by fuzzy sets with multi-semi functions of belonging. Wavelet Method For Solving Problems Of Unsteady Fluid Filtration In The Crack-Porous Ring Type Formation O.A. Dyshin Based on the multiple-scale analysis in L^2(R^3) using discrete wavelet transform with separable orthonormal basis we’ve developed a method of sustainable approximate calculation of the classical solution of the initial-boundary value problem of unsteady fluid filtration in the crack-porous ring-type formation. The problem is reduced to solving ill-posed problem of finding the solution of linear polynomial equation given inaccurate data, when the approximate solution constructed by regularization method is stable with respect to error in differential equations ratios and boundary conditions set up, as well as set up right member falseness. Decision Making In The Multi-Criteria Problems Of Alternatives Using The Bayesian Interval Inference Methods R.F. Hajiyeva The Bayesian inference method is used in the decision process of the multi-criteria problems using the strength of information on the product rules. Using these mechanisms the point and interval estimates of the posterior probabilities are built on their prior probabilities, derived from the composite aggregation rules of the alternative description information of the decision-maker preferences defined by a fuzzy expert judgements. These decision logic is applied to the problem of selecting a candidate on the vacant faculty position in university Comparative Analysis Of Trading Systems Performances With Respect To Transaction Cost E.J. Janahmadov The purpose of this paper is to compare and analyze the performance of trading rules applied to the underlying and derivative products. Three different trading market indictors were chosen from the range of trading rules according to their performance relatively to Dow Jones Industrial Average. On the basis of these technical indicators the automated trading systems were developed and then applied to the underlying instrument such Dow Jones Industrial Average. The performances of trading systems and profit/loss indexes were compared and analyzed. The results are compared with “buy-and-hold” strategy and performance of underlying security. The results of the research intend to show the effect of the transactions costs on the performance of trading systems and optimal could be applied to invest into underlying or derivatives of underlying.

Mineral Composition And Textural-Structural Peculiarities Of Ore, And Mineral Formation Stage Of The Gedabey Gold-Copper Deposit (Lesser Caucasus) M. Aliyev, G. Huseynov The mineral composition and textural and structural characteristics of ores are studied, also the phases and stages of mineralization, which are an important source of information on the conditions of formation of the deposit, time allocation of gold and its spatial association with certain mineral assemblages and associations. Consideration of these issues can come to an understanding of the factors behind the differences in the scale and extent of gold deposits of various types, as well as to form a mineralogical search features gold-bearing mineralization. Development Of Decision-Making Algorithm On Efficiency Of Operators And Traffic Controllers Of Air Transport Based On Their Psycho-Physiological Conditions And Productivities R.M. Jafarzade, T.R. Jafarzade By processing the data on the human-operator active performance with respect to their psycho-physiological conditions and productivities in the human-machine systems, we developed the algorithm for the possibilities of further execution of their (operator) duties in the incomplete and unclear initial data. Using fuzzy clustering and the interval fuzzy sets of the second type, and the coordinated assessment of expert opinions on the binary relationship of objects from the class with recommendations on the further implementation of their activities, we obtained the individual assessment of the alternative recommendations for each of the tested objects from the set of objects. The calculation for the experimental data is provided. The proposed approach can be used for the adaptive selection of recommendations on the continuation of duties of air operators and air traffic controllers by taking into account the dynamic of changes of their psycho-physiological states and productivities.

Excerpt from The Tribes and Castes of the North-Western Provinces and Oudh, Vol. 4 of 4 Mughul, Mughul. - One of the four great Muhammadan sub divisions known in Europe under the form Mongol. Mr. Ibbetson, ' writing of the panjab, does not attempt to touch upon the much debated question of the distinction between the Turks and Mughuls. In the Delhi territory, indeed, the villagers accustomed to describe the Mughuls of the Empire as Turks, used the word as synonymous with official, and I have heard my Hindu clerks of Kayasth class described as Turks, merely because they were in Government employ. On the Biloch frontier the word Turk is commonly used as synonym ous with Mughul. The Mughuls preper probably either entered the Paujfib with Babar, or were attracted thither under the dynasty of his successors; and I believe that the great majority of those who have returned themselves as Mughuls in the Eastern Panjab really belong to that race. In these Provinces they say that they take their name from their ancestor Mughul Khan. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Widely recognized as a groundbreaking text, The New Urban Sociology is a broad and expert introduction to urban sociology that is both relevant and accessible to the student. A thought leader in the field, the book is organized around an integrated paradigm (the sociospatial perspective) which considers the role played by social factors such as race, class, gender, lifestyle, economics, culture, and politics on the development of metropolitan areas. Emphasizing the importance of space to social life and real estate to urban development, the book integrates social, ecological and political economy perspectives and research through a fresh theoretical approach. With its unique perspective, concise history of urban life, clear summary of urban social theory, and attention to the impact of culture on urban development, this book gives students a cohesive conceptual framework for understanding cities and urban life. In this thoroughly revised 5th edition, authors Mark Gottdiener, Ray Hutchison, and Michael T. Ryan offer expanded discussions of created cultures, gentrification, and urban tourism, and have incorporated the most recent work in the field throughout the text. The New Urban Sociology is a necessity for all courses on the subject.
