Book excerpt: Issue 01 Oct-Nov-Dec 2013 The Multi-Fructural Analysis Of Fatigue Failure Under Friction Process A.M. Pashayev, A.Kh. Janahmadov, O.A. Dyshin, M.Y. Javadov The article shows the need to combine approaches of synergetics and fractals in the study of friction and wear in the frictional contact, due to fact that dissipative structures, self-organising in the open systems, are known to have a fractal behaviour The multi-fractal concept allows to introduce new quantitative structures, characterised by a spectrum of generalised fractal dimensions and reflected by the degree of randomness. Different levels of structure (micro-, mesa- and macro-scale) are described in the framework of multi-fractal analysis. A procedure to calculate the multi-fractal dimension of this structure is developed and the results of the numerical calculations are submitted.Research Of Loading Distribution On Coils Of Running Pair Of The LatchN.H.JavadovIt is given the calculation procedure of distribution of pressure on coils of running pair of latch at various loading schemes. Recommendations are provided for the choice of loading schemes of running pair, which ensures more uniform distributions and therefore, considerably reduces the wear of coils by means of constructive changes in a latch. Modeling And Forecasting The Financial Markets Using Theory Of Deterministic Chaos And Fractals S.M. Javadova This paper presents the results of the multi-fractal analysis based on the wavelet transformation, which can be considered as method of studying the spectral correlation properties of various processes, including non-stationary. Comparative experience with methods MFFA (multi-fractal fluctuation analysis) and WTMM (wavelet transform modulus maxima) in studying of the multi-fractal properties of signals of time function shows that MFFA method is more reliable and robust.As an instrument of the ‘local’ study of time function structure, WTMM allows to evaluate the correlation properties of random processes in comparison with a short signal. Surface Structures Of Frictional Materials On Asbestosfree Base M.I. Aliyev Development of asbestosfree composite materials on petroleum coke base enabled to obtain environmentally sound products with sufficiently high physical, mechanical and tribotechnical characteristics. The materials have been analyzed/tested from the perspective of physicochemical friction mechanics in the breaking mode through the differential-thermal analysis (DTA) and thermogravimetric analysis (TGM), supplemented with the study of friction materials structure. The thermogravimetric analysis findings indicated that decomposition of the new asbestosfree friction material begins after 14 minutes at 3000C.

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.

Relations Of Cytokine Blood Spectrum With Nephropathy At Patients With Diabetes A.N. Babakhanova Work objective is to study the cytokine status of patients with diabetes of type 1 and type 2 with a complicated nephropathy and an uncomplicated course. 123 patients with diabetes and the control group of 20 people were inspected. By the immune-enzyme analysis of ELISA the levels (INF-γ, TNF-α, IL-6, IL-1β) were determined in blood serum of the patients. The most expressed changes of the cytokine status were observed in the patients of diabetes of type 1 and type 2 which were expressed in the initial increase of the maintenance of all studied pro-inflammatory cytokines (INF-γ, TNF-α, IL-6, IL-1β). Such changes in activation of the pro-inflammatory cytokines characterize this disease as an inflammatory immune-dependent process. The changes in the cytokine status had a non-uniform character with the most expressed changes in IL-1β, TNF-α, INF-γ synthesis (p ≤ 0,001) and a slight increase of IL-6.

Book excerpt: 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.

Book excerpt: Issue 10 October-November-December 2016 Assessment Of Material Strength Properties Of One Scale Level Transferred From Test Data At Another Level A.M. Pashayev, A.Kh. Janahmadov, M.Y. Javadov The paper examines the forecast methods of failure process dynamics at one scale level based on parameters defined at another level. The industrial forecast methods were developed suited for engineering practice. The specific scale levels of fracturing are considered on the basis of the dynamic process characteristics and the space-time approach. Space-Time Scale Invariance At Dynamic Fragmentation Of Quasi-Brittle Materials N.G. Javadov, M.I. Aliyev The paper examines the fractured quasi-brittle materials and the scale invariance with respect to time and space variables. It confirms that the large-scale clustering in the ensemble of defects, accompanying the transition from the dispersed to the microscopic resolution, have the signs of phenomena that is characteristic to non-equilibrium critical systems. It demonstrates that with respect to the quasi-brittle materials, the dissipative ability is associated with the scenarios of formation and interaction of the multi-scale collective defect modes in conditions of the specific type of the critical events – the structural scaling transitions. Nano-Tribological Processes At Electric Discharge Of Discrete Ohmic Contacts Of Metal-Polymer Pairs A.Kh. Janahmadov, A.I. Volchenko, E.S. Pirverdiyev The paper examines the nano-tribological processes at the electrical discharge in the discrete ohmic contacts of the metal-polymer pairs of tribosystem. The nature of destructive processes in the polymeric film of pads is explained. Adjusting The Starting Pressure Of Gas Lift Well To The “Switching Lifting Device Of The Reverse Valves System” O.H. Mirzayev The results of starting pressure change by switching injection direction of working agent from circular annulus to the central part in gas lift wells have been given. The valves are placed on the pipe surface in definite depth under liquid column. As a result of investigation it has been determined that the application of the method in the wells with big depth and high liquid column gives an opportunity to reduce starting pressure. Application of the method in complicated exploitation conditions gives effective results. Comparative Analysis Of Trading Systems Performances With Respect To Transaction Cost (Part 2) E.J.

Download or read book Crowdfunding and Entrepreneurial Finance written by Richard T. Harrison and published by Routledge. This book was released on 2017-10-02 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increase in the restrictions on the availability of funding for new and growing businesses in the aftermath of the global financial crisis has been accompanied by the emergence and growth of crowdfunding as an alternative method of raising capital. Crowdfunding contributes towards the disintermediation of the finance market as funders and promoters are brought together directly, democratising both fundraising by businesses and investment by individuals. This book extends entrepreneurial finance research to the study of crowdfunding. Contributions review the history, status and future of crowdfunding, analyse the patterns of fundraising, assess the potential of crowdfunding for the financing of social ventures in particular, and discuss the regulatory implications of recent developments. What is clear from this collection is that the crowdfunding space is still evolving, institutional forms are still developing as models are refined, new institutional collaborations (e.g. between equity platforms and business angel networks) are emerging, and new challenges, particularly regulatory challenges, are being encountered. While crowdfunding is not a universal solution for SME finance in a post-crisis financial landscape, it remains too early to determine whether crowdfunding represents a large-scale transformation of the early stage risk capital market or a minor addition to it. This book was originally published as a special issue of Venture Capital.
