Book excerpt: Issue 11 January-February-March 2017 Studying On Stability Of Piezoelectric Actuators Of Initial Alignment System Accelerometers A.M. Pashayev, T.I. Karimli, V.A. Neymatov The article investigates the servo actuator system of the initial alignment of the piezoelectric accelerometers in automatic operational mode, which eliminates the parasitic transverse sensitivity. There were developed the transfer functions of the piezoelectric drive of the turntable, built and performed a simulation modeling. The resulting oscilloscopes of the simulation model confirm the reliability of the proposed calculation method for the position regulation parameters, to ensure the necessary nature of the transition process.

Book excerpt: Issue 06 Jan-Feb-Mar 2015 Physical Mesomechanics And Spectrum Of Metal Surface Layer Excitation At Friction Process With Heavy Loading A.Kh. Janahmadov, N.G. Javadov The paper reviews the physical mesomechanics of structurally inhomogeneous media, developed on the verge of continuum mechanics (macro-level) and physics of plasticity and strength of deformable solids (micro-level). According to the concept of the structural level of deformation, at friction the surface layer of deformable solids is an independent leading functional subsystem. It is shown that with an increase of the deformation level of material, it develops autonomous processes (plasticity waves) inside, which have a significant impact on the staginess of plasticity flow localization and the destruction of contacting bodies, at the meso-level the deformation has a transitional-rotational character. Influence Of Wingtips On Induced Drag Force Of Rectangular Wing R.M. Jafarzade, M.H. Ilyasov, J.N. Huseynli The paper examines the influence of wingtips on the inductive resistance of rectangular wing through the mathematical model based on the distribution of vortices. Assuming that the free vortices originate at the wingtips – the imaginary Π-shape vortex diagram is built above the wing at the height of wingtips. The air is considered to be incompressible. Referring to the Biot-Savart formula, the expression for the inductive velocity, generated by the free vortices, and their average values along the wingspan are found. The induced drag force and its co- efficient are determined through the average bevel angle of flow. The inductive drag force is analytically proven. Application Of Coordination Polymers To Increase The Reservoir Oil Recovery B.T. Usubaliev, E.E. Ramazanova, F.T. Murvatov, E.N. Aliyev, Y.S. Salakhova, M.K. Munshieva, F.B. Aliyev, A.K. Rzaeva It is first time when an application of composite materials, BAF-1 BAF-2, on the basis of the co- ordination polymers is studied to improve the rheological properties of crude oil. It has been established that composite materials reduce the oil viscosity by 60-70% and also have a positive effect on other properties. Relaxation Of The Non-Equilibrium Field Effect In In2O3-SiO2-Si-SiO2-Al Structures At The Non-Equilibrium Depletion Regimes A.Z. Badalov, Sh.G. Zeynalova The article studies in detail the effect of various factors on the screening time of In2O3-SiO2- Si-SiO2-Al structures, the influence of the lighting temperature, and the supply voltage on the duration of the non-equilibrium non-stationary depletion process. It is also examines the dependence of the current depolarization on the power supply impulse duration with and without exposure to the LED light. The Theoretical Analysis Of Crude Oil Vapour Pressure And Cavitational Technologies Studying Of Physical And Chemical Properties Of Transported Oil In The Course Of Cavitation S.K. Gezalov We have worked out the criterion of fuzzy interval for minimizing target function with fuzzy coefficient. The given criterion shows adaptability of genetic algorithms for building pare-to-optimal solutions of multi-objective problem of transport logistics with fuzzy coefficient of objectives.

Book excerpt: Issue 04 July-Aug-Sept 2014 Diagnosis Of The Contact Interaction Of Solid Bodies At Friction Using Fractal Analysis Methods A.Kh. Janahmadov, M.Y. Javadov, O.A. Dyshin Were developed the additional quantitative research tools of the surface roughness: the fractal dimension of curvature on the bearing surface and the fractal dimension of profilograph. These values are used to classify the regimes of the contact interaction of the metal elements at friction and to diagnose the form of contact according to the fractal dimensions scale, which describes the main three types of contacts: elastic, elastic-plastic and plastic. The Stock Price Valuation Based On The Stochastic Modeling Of Financial Data S.M. Javadova The stochastic model is developed to forecast a movement of stock prices as function of the Wiener process. The canonical decomposition of function values through discrete number of points is used to generate the Wiener process. Factors Causing Corrosion And Destruction of Coating in Operation of Oil-Field Pump N.G. Javadov, A.M. Mehtiev The paper review and analyzes factors that contribute towards corrosion and destruction of coating during operation of oil-field pump. It is noted that factors such as cold, moisture, heat, corrosive components of pumped fluid, mechanical stress, etc., have negative impact. 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.
