The paper proposes a model system for managing the process of formation of professional skills of trainees during exercise using a computer simulator. A distinctive feature of the proposed system models is the opportunity for the shortest time to achieve a high degree of quality development and skills by computing the integrated assessment exercise learners based on a number of quality indicators with different physical nature (using fuzzy set theory and the analytic hierarchy process) as well as full control of the dynamics of the development of skills in view of the gradual development of skills with repeated exercises under repeatability conditions (using mathematical models of iterative learning).

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 paper proposes a method of calculating the amount of visual information in an image. The method is based on the model of local analysis in the early vision. We are talking about the information perceived by an observer under certain conditions, not about the information contained in the raster image per se. Simple striate cortex neurons respond to the simple visual features of image, for example, the bright stripes in a dark environment, and the brightness gradients. To evaluate the amount of information in the image, it is possible to take the ratio of the number of activated neurons to the total number of neurons in a model. It is necessary to consider the angular size of the image to calculate the value of the estimate.

The parameters of high-evoked activity of the human brain during the perception of Kanizsa figures in various cognitive tasks has been investigated. Wavelet analysis of EEG has been demonstrated that the perception of subjective contours associated with gamma responses (30-90 Hz) in different areas of the cortex to the specific spatio-temporal patterns. This pattern indicates the formation of fronto-centro-parietal neocortex system interactions, providing the perception of distributed information.

In this report, we propose an approach to the automatic extraction of such components of the image, that are most useful for human observers to solve the recognition task. This approach is based on the concepts of psychophysiological mechanisms of grouping the simple features at the preattentive stages of visual processing. A method is based on digital image processing by a software implemented model "filter-rectify-filter". The extraction of the most informative areas of the photograph is based on finding local maxima of the model "outputs". The calculation results indicate that the areas of the image containing spatial modulations of the local features may be very useful for the recognition of faces.

The methods for the detection of faults of actuators, devices and algorithms for fault tolerance were considered. The problem of fault diagnosis is an important aspect in the design and use of control systems. Marine objects are complex hardware and software systems involved in the tasks taking place in uncertain environments, there is a way the degree of autonomy becomes an important issue. Therefore, the ability to detect and to continue to maintain the health while an error or equipment failure is a key factor for the successful completion of the mission or the resumption of the previous state of the object.

Article is devoted to solving the problem of video compression for panoramic video surveillance system. The actuality of the problem associated with both the limitations of existing solutions, as well as the peculiarities of video streams, which in many codecs are not counted. The novelty of the work is related to the fact that the role of the key frame is performed by image of background estimation (not by a frame from input video stream). In this paper we used the ideas of the four mainstream approaches in the field of compression (segmentation (division into a dynamic component and a static background), JPEG-compression, reduce the frequency of transmission of the reference frame (image of background estimation), the ability to change the resolution of the frame, the synthesis of the output image). The solution of problem of compression is produced by division of video frames into separate semantically meaningful elements (objects, background) transmitted over a communication channel with varying degrees of detail depending on the semantic significance and accompanied by metadata. It is experimentally proved that the value of the compression ratio of the video stream K = 135 times at peak signal to noise ratio PSNR = 32 dB, which allows to send the panorama of resolution 3072x720, stitched from the three cameras, through the channel with a capacity of 10-11 Mbit / s.

Testing and debugging of real equipment is a time consuming task. In particular, in the case of marine robots, it is necessary each time to carry out the transportation and deployment of a robot on the water. Experiments with not yet fully functional prototype of marine robot equipped with expensive hardware is in the meantime very risky. Therefore, the use of simulators is affordable way to accelerate the development of robotic systems from the viewpoint of labor effort and cost of experiments. This paper presents a simulator specifically designed for autonomous unmanned underwater vehicles.

With the development of market relations and the increasing competition in the Russian work with the end consumer is becoming increasingly important for each market participant. Consumer behavior - a new field of knowledge that will help market participants to maintain and even increase the profitability of of their business at relatively low material costs. The fastest way to increase income of the company without investing significant resources, is to increase customer loyalty. For the numerical evaluation and opportunities to influence on customer loyalty is computed the customer loyalty index. To increase the effectiveness of measures taken to study and improve customer loyalty index developed a set of program measures on the basis of 1c Alfa Auto. Using the developed software, the process of influence on customer loyalty index, and hence the profits of the enterprise is more efficient both in terms of spent time , and in terms of the effectiveness of taken measures.

Nowadays many researches devoted to the problem of health of the individual, have become of a major significance. Scientific interest is high as there are many challenges and risks contemporary individuals face. Today we come across many publications where the health phenomenon is being analyzed from different perspectives. Questions of health are the subject of interdisciplinary research as a plenty of different sciences are involved into all levels, say, theoretical and applied. This article is some systematization of the results of two applied researches of 2014 in the frames of Southern federal university, Rostov-on-Don, Russian Federation. The main aim of the researches was to determine and describe the basic content of physical and emotional so called components of health of contemporary student youth and factors determining them. We questioned 232 students. Resuming some results we can say that because of contemporary needs of the society students have to put getting good education and career escalation as the main priorities in their life. They also worry about problems of ecology and health. In particular smoking and alcohol drinking. Our results again coincide with the results of other researchers that there is no gender difference here: both young women and men tend to smoke and drink alcohol – girls practice “men’s behavior pattern”. Students are stressed and that is the main reason of their drinking. They underline determination of some social factors, as political situation, changes in the Russian society, etc. Sociologists are expected to research mentioned problematic field more thoroughly.
