Azerbaijan Technical University is a public university, specialized in engineering, located in Baku, Azerbaijan. The University has 9 schools and 54 departments, 884 faculty members and approximately 6500 students.The University traces its history to the much older Baku Polytechnical Institute. On November 14, 1920, the Soviet government decreed that the previous technical school, Baku Polytechnicum, would close and be replaced by Baku Polytechnical Institute, a more traditional polytechnic institute. The new school focused on training engineers in a broad range of industries: agriculture, civil engineering, electromechanical, economics and oil. The new school went through many name changes over the years as its emphasis changed to meet the needs of Azerbaijan. In 1923 the school changed its name to Azerbaijan Polytechnical Institute. In March 1929, the Azerbaijan Communist Party decreed that the school be split into three independent schools covering agriculture, economics and oil. However, the expanding needs engineers in other areas outside oil resulted in expansion in the school's curriculum and the school changed names again in 1934, this time to the Azerbaijan Industrial Institute as it was merged with civil engineering. World War II taxed the Soviet Union and schools like Az. I.I. struggled to stay open. At the end of the War, there was great demand for oil engineers in the Soviet Union and the school trained them in great numbers. In 1950, the government founded a separate Azerbaijan Polytechnical Institute and moved non-petrochemical curricula to the new school so that Az. I.I. could focus on the oil industry . In 1970, a branch of AzPI was founded in Ganja. In 1993, AzPI changed status and became Azerbaijan Technical University. Wikipedia.


Speeds of sound in liquid n-heptane, n-octane and their binary mixtures were measured at the temperatures T = 293.15 to 523.15 K and pressures up to 60 MPa. The pulse-echo method with a frequency of 8 MHz and uncertainty of ±0.08% was used. The measured values were fitted by polinomials, as functions of temperature and pressure, and the reliability of the present results was proved by comparison with the literature data. © 2012 Pleiades Publishing, Ltd.

A new approach to constructing robust feedback control systems for nonlinear nonstationary SISO plants with an incomplete mathematical model is proposed. Based on the Lyapunov function method, the initial system is transformed into a degenerate linear system (reduced system) with components of a model of an indeterminate plant being involved in its right part. The robust control strategy lies in suppressing a plant's model as a potential source of parasite dynamics and reducing the reduced system to a homogeneous equation. The proposed OBS suppressor hyperobserver of a model's dynamics allows one to reduce the effect of various uncertainties to an indefinitely small value with the simultaneous preservation of the desired dynamics of the reduced system. The desired qualitative characteristics of the reduced system are set by choosing the tuning parameters of a PD controller of the (n - 1)th order. The contrastive analysis of the solutions to a benchmark problem using the Matlab/Simulink package leads to a number of conclusions that are of great practical importance. © 2013 Allerton Press, Inc.

In this study, the torsional vibration and stability problems of functionally graded (FG) orthotropic cylindrical shells in the elastic medium, using the Galerkin method was investigated. Pasternak model is used to describe the reaction of the elastic medium on the cylindrical shell. Mixed boundary conditions are considered. The material properties and density of the orthotropic cylindrical shell are assumed to vary exponentially in the thickness direction. The basic equations of the FG orthotropic cylindrical shell under the torsional load resting on the Pasternak-type elastic foundation are derived. The expressions for the critical torsional load and dimensionless torsional frequency parameter of the FG orthotropic cylindrical shell resting on elastic foundations are obtained. The effects of variations of shell parameters, the exponential factor characterizing the degree of material gradient, orthotropy, foundation stiffness and shear subgrade modulus of the foundation on the critical torsional load and dimensionless torsional frequency parameter are examined. © 2012 Springer Science+Business Media Dordrecht.

This article addresses difficulties in developing a knowledge base for application to educational environments. To solve this problem, fundamental principles used for building similar systems are proposed. A mathematical model is chosen to propose a mathematical design of educational materials based on linguistic variables. A membership function of knowledge evaluation and an architecture of fuzzy knowledge were created, on the basis of a set of two types of fuzzy rules that cover all possible situations in the educational environment, with a demonstration of its application based on the original method of selection questions for procedure evaluation of student knowledge. In the end, the studies analyzing the utility of the experiment clearly showed an increase in the efficiency of the educational process, with the advantage of applied models and technologies in the long term.

In this paper, intellectual technology is applied with the device of fuzzy logic as the basis of a developed system of learning and testing. This system is used to automate the process of teaching and control of knowledge of students in higher education institutions. The quality of the intellectual learn learning system directly depends on the accuracy of the definition of the student's current level of knowledge, as well as the choice of a learning strategy. It can be a transition to teaching new material, review of old material, or the learning completion. Source
