A design of the actuator, consisting of a thin layers of silicon dioxide and aluminum is proposed. There are calculations made of the response speed and heat dissipation of the actuator. By making the best selection of layer thicknesses and optimization stages of technological process, in particular the deep selective etching of silicon, the best performance on the angle of inclination of the actuator and the speed of the device could be achived. The greater the difference between the initial temperature and the heating temperature, the stronger the beam of the actuator is lowered to the plane of the silicon plate, and, therefore, less angle of elevation above the surface of the silicon plate. It is thus possible to control the angle of the beam by selecting the appropriate heater and voltage, providing the desired temperature. The design of the micromirror device based on the proposed actuator is provided. The developed design is based on the actuator and allows for controling the tilt of the mirror in a wide range.

Briefly discussed the theoretical model of the spectrum of RR intervals and its changes depending on the processes taking place. Made a device for measuring cardiointervalogramms (CIG). Obtained from the renting of data, of varying duration and frequency shall be recorded for further processing. The analysis revealed that the resulting spectrum satisfies the conditions considered in the theoretical model, and can be further analyzed with fractal characteristics. Such an analysis is of great importance in the diagnosis of the patient directly to the duration of the therapeutic procedure for the optimization of both time and intensity exerted influence.

Keywords: CIG; fractal series; the spectrum of RR intervals

One of the most widespread endocrine diseases in the world is diabetes therefore its true diagnostics, and also diagnostics of its complications (encephalopathy, complications in cardiovascular system, etc.) is always actual. During carrying out research the analysis of psychological testing of examinees was carried out. Also in this work the attention is paid to application of methods of the statistical analysis for classification of EEG of patients by diabetic encephalopathy and healthy examinees. The most informative indicators of EEG reflecting cognitive functions of a brain were revealed. The interrelation of results of psychological testing and EEG analysis is established.

Keywords: electroencephalography, diabetic encephalopathy, discriminant analysis

Most of web pages of the Web are inaccessible for the blind users. And the main reason is a lack of the semantics at the source code (technical) level of web pages and absence of the navigational components. In this work we propose a new web page representation---multiaxial navigation model---representing web documents in the form convinient for the blind users. Moreover, we present methodology for the navigation on the model proposed, that ensure an efficiency of user mobility. Automatic transformation of a web page into the multiaxial navigation model and navigation means are realized in the Blindzilla prototype. An efficiency of the proposed concepts is proven experimentally regarding contemporary screen readers, such as JAWS, Window-Eyes, and Fire Vox.

  The article is devoted to the problem of the research of geopolitical processes on the world regions’ scale under present-day conditions. The article substantiates the necessity of their analysis with the help of the cognitive approach as an effective means of cognition of the interconnections and interrelationships within the complicated systems. With that aim in view the specifics and the stages of the cognitive modeling are given thorough analysis in the article. This type of modeling is adapted to the analysis of geopolitical dynamics on the regional/sub regional level taking into consideration its aptitudes to make prognostic scenarios of the development of the situation. The possibilities of the cognitive modeling of geopolitical processes are illustrated on the example of the situation in three sub regions constituting one (big) the Black Sea – Caspian region.

After accession of Russia into the WTO the tasks related to the development of infrastructure have been sharpen. With the growing volume of cargo traffic and the lack of opportunity for the extensive development of the port infrastructure, the alternative of building the dry port can be only feasible, although explicitly the most expensive. Due to this reason the method of gradual development of the dry port which provides significant economic efficiency was addressed in the article.

Keywords: dry ports, net present value, the efficiency of the investments

Decision making in the organizational and technical systems is complicated by the risk of various events emergence in the systems with a given probability. The article describes a method for supporting decision making under risk on the basis of integration of evolutionary, multi-agent, simulation models and numerical methods. In the course of the method's work the following steps are performing: a set of alternatives solutions is formed;  transition to a one-criterion alternatives evaluation is fulfilled by using linear convolution; transition to the system behavior certainty is fulfilled with the use of numerical optimization Bayes-Laplace criterion. The developed method is applied to solving the projects scheduling problem; the results agree with the problem solution that has been performed by using genetic algorithm method under certainty.
