Kazan State Technical University named after A. N. Tupolev was established in 1932. The history of the university is closely related to the progress of Russian aeronautics. Until the recent time, it was well known as Kazan Aviation Institute . In 1973, the Institute was named after Andrei Nikolayevich Tupolev, the prominent aircraft designer. In 1992, it got the status of the State Technical University.Today the University is one of the leading Russian institutions in aircraft engineering, engine and instrument production, computer science and radio and telecommunications engineering. KSTU is the largest technical university of the Republic of Tatarstan and the Volga region.Kazan State Technical University teaches about 25,000 students on 65 majors in Engineering, Business and Humanitarian science by the university faculty body of 1,800 persons, including 150 Full Professors & Doctor of Science degree holders, 600 Associate Professors & Ph.D. degree holders.The University includes the following institutes and faculties: Institute of Aviation, Land Vehicles & Energetics Institute of Automation & Electronic Instrument-Making Institute of Technical Cybernetics & Informatics Institute of Radio-Engineering & Telecommunications Institute of Engineering & Economics Institute of Social Technologies Physics & Mathematics Faculty Institute of Business & Innovative TechnologiesKSTU includes 11 associated branch institutes outside Kazan in the towns of Almetevsk, Bugulma, Chistopol, Elabuga, Leninogorsk, Naberezhnye Chelny, Nizhnekamsk, Volzhsk, Vyatskie Polyany, Zainsk, and Zelenodolsk.The University is housed in 8 buildings. It has 6 student dormitories and a hostel. A sport complex includes 5 well-equipped indoor sports halls. The University also has a sportive camp in a picturesque place on the Volga river, 40 km away from Kazan. Wikipedia.

2013 9th International Conference on Antenna Theory and Techniques, ICATT 2013 | Year: 2013

In the paper, the method of antenna synthesis, which was proposed and developed by V.N. Dymsky and extended by his disciples, is presented. It combines mathematical formalism of functional spaces and profound physical interpretation. Some original concepts are introduced, such as the power radiated in the desired antenna pattern, the pattern's relief deviation, error sensitivity coefficient, purely radiating distributions, etc. The adjoint operator transforms a desired radiation pattern into the distribution that has a number of useful properties. It can be used in various iterative algorithms for solution optimization. Moreover, it 'suggests' the rational placing of antenna elements. Quite often, there is a need to synthesize the desired radiation pattern and at the same time meet rigorous requirements for the near field's structure. The way to extend the adjoint operator method to such tasks is discussed. Numerous calculations illustrate the main results. © 2013 IEEE.

Welding International | Year: 2015

The mechanism of formation of the welded joint in laser welding with burning through of dissimilar and identical materials is investigated. The welded joints are examined by metallographic methods and mechanical tests, and the special features and the properties of the metal of the welded joint, and the weld zone and the parent metal of the welded components are described. © 2014, © 2014 Taylor & Francis.

Particular results of the development and burning of the high frequency capacitive discharge (HFCD) between a drop-jet electrolytic electrode and a flow-type electric cell are presented. Significant current and voltage pulsations taking place after the electric breakdown in the process of the HFCD burning confirm the multichannel shape of the discharge burning at atmospheric pressure. Three modes of HFCD burning between the combinations of the drop-jet electrolyte and the surface of the flow-type electrolyte have been specified. An HFCD with glowing luminescence and "streamer discharges" at the copper tube surface when the electrolyte jet is fed under the pressure of 3 × 103 Pa has been discovered. © 2013 Pleiades Publishing, Ltd.

In this paper time-variant systems with sector nonlinearities tending to be affected by bounded external disturbances are considered. We present an approach to solving problems of state estimation, stability, boundedness relatively to given sets, rejection of bounded external disturbances and initial deviations by using static linear state feedback, based on matrix comparison systems method and differential linear matrix inequalities.

A mathematical model of the process of bending and rolling the thin-walled components is presented taking into account the geometrical nonlinearity. Also presented is the technique for calculating the setup variables of bending equipment, which is based on reduction of the initial differential boundary-value problem to the discrete one with the use of the finite difference method. © 2011 Allerton Press, Inc.
