The article deal with gradiometer is designed for remote nondestructive testing of various purposes pipelines. Gradiometer sensor consists of two Hall-effect transducers three-component magnetic field placed at a distance of 1950 mm from each other. The specialized algorithm for reducing transducer’s bias error is used. The gradiometer sensor’s orientation relative to the pipe axis is determinate by the digital microelectromechanical system. The results of measuring the gradient of the magnetic field induction, module, and the coordinates of the sensor are displayed on the LCD display and saved on non-volatile storage.

The optimization of multilayered one-dimensional nonlinear structure of Raman amplifier of optical signals consisted of alternate active nonlinear metal layers and passive dielectric has been studied. The amplification of the reflected and passed field energy was calculated for different structure types. The effective replacement of passive layers by active media in the middle and in the end of structure has been demonstrated.

From the point of view of development of control systems, a significant disadvantage of indirect adaptive control systems of moving objects is the fact that the limiting the properties of such system are determined by the basic adaptive regulator. In other words, to solve the problem of adaptive control it is required to find a non-adaptive regulator, which solves the problem of marine autonomous vehicles. In this case, the adaptive controller replaces many controllers that solve the control of multiple objects in a non-adaptive domain. The paper presents method of direct adaptive control for marine autonomous vehicles. Nonlinear mathematical models are considered. The method is based on position-trajectory control approach. It is proved the designed by suggested method controller is a vector nonlinear PI-regulator. The regulator ensures asymptotical stability of the closed-loop control system.

The presence of colossal dielectric constant in the low frequency region is observed in the strontium ferrite with hexagonal structure. This result can be explained in the framework of the "grain-layer" and the polarization of Maxwell - Wagner in the ceramic medium. The effect of negative capacitance in ceramic strontium hexaferrite at a frequency of less than 2.10 Hz has been detected.

This article describes new method of correction of magnetic field MPFS TWT. The method allows controlling the magnetic induction instead of the current coefficient of retarding system. This approach reduces time and increases quality of correction. The key point of the method is in controlling of magnetic field on the assembly stage. The iteration algorithm of correction was developed. It is necessary to remember the coordination of the point, which need to be corrected. After measurement the researcher will know the result of influence of correction, which he or she applies to the system. In such way all magnetic system need to be controlled. This article represents the result of this approach and shows its benefits and lacks.

This scientific research is directed on measurement of level of satisfaction of students with a cultural and leisure complex of Rostov-on-Don, ability of cultural infrastructure to sustain inquiries of the population, and reveals the problematic side of the existing cultural complex. Research took place from December, 2013 to May, 2014 by a questioning method. It's received low level of satisfaction with the functioning of the cultural complex among young people. Revealed a low level of interest of the population in their cultural development. It is shown that the existing cultural infrastructure is not able to fully perform their functions of the cultural development of the population and neeeds to change.
