Specific Kaliningrad character of the Russian identity

There are different levels of territorial identity perceived as a sense of belonging to a particular social and territorial community. People residing in any region identify themselves with these levels to a different degree. Since 2001, the authors have been doing sociological research into the territorial identity of the population of the Kaliningrad region, which became a Russia's exclave after the demise the USSR. The research shows that residents of the Kaliningrad region associate themselves with different territorial communities to a varying degree starting with an ever strengthening sense of national identity, followed by the regional and local identity. The sense of macro-regional (European) and global identity is significantly lower

Development of Deflection Angle Stabilizing System for Balancing Robot

This paper performs determination of a mathematical model of the balancing robot, its linearization and algorithm for calculation of stabilization of the deflection angle from the vertical modal method. This algorithm also makes determination of the angle of deviation from the use of either alpha-beta filter and the angle of rotation of the wheels by means of encoders

GAS DYNAMICS OF WORKING FLUID INLET INTO CHAMBER OF ROTARY EXPANSION MACHINE

In this article, a mathematical model of working fluid inlet into chamber of rotary expansion machine from source of superheated steam. The main practical problem that can be solved on the basis of this model is to determine dependence of torque on the angular velocity, i.e. in the construction of mechanical characteristics of rotary expansion machine.

SYNTHESIS OF THE LOW-FREQUENCY VIBRATION EXCITER

The article is devoted to synthesis of the low-frequency vibration exciter for checking of sensors of acceleration. In many areas of the modern equipment sensors of acceleration working in very low range of frequencies are widely used. For checking and graduation of such sensors the vibration exciter capable to provide rectilinear horizontal harmonic oscillations of the calibrated accelerometer in so low range of frequencies are required. Low frequencies of fluctuations cause the necessity of creation of big amplitudes of movements for ensuring the acceptable values of amplitudes of accelerations. The low-frequency electrodynamic vibration exciter with a magnetic suspension of mobile part which is a component of the National Standard of the vibration movement of the Russian Federation is so far created. However, development of the modern equipment demands expansion of frequency ranges to the area of ultralow frequencies. One of requirements shown to the vibration exciter working in the ultralow range of frequencies is increase in amplitude of horizontal movements of a mobile part as with small amplitudes the speed and acceleration of the harmonious law of the movements proportional according to the frequency of fluctuations and a square of this frequency, will have small amplitude values. One of problems of realization of a control system of the electric drive of the vibration exciter consists in that a mobile part possesses indifferent position of balance. The centre of fluctuations of a mobile part is not defined and can be in any point on magnetic conductor length. That fluctuations had the steady centre in an average point of a magnetic conductor without use of a mechanical spring, the drive is supplied with an additional control system of fluctuations, or a so-called electromagnetic spring
