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.

Software and hardware solution for the operational monitoring of the technical state of water conveyance structures designed to determine the various parameters of defects and damages, as well as of the forecast period the residual life of their members. It can be used to estimate the geometric parameters of each defect, namely - the location, depth, width, height, and operational evaluation of residual life - namely, predicting the total number of cycles of freezing and thawing, as the last for the period of operation, and the remaining to loss of bearing capacity of concrete elements water conveyance structures, and complex influence of several factors on the reliability of the plant and the most characteristic of them is abrasion, leaching processes and the degree of wear on sites with different hydraulic characteristics. Software and hardware solution can be equipped with various combinations of frames, copies the form of water conveyance structures.

Keywords: the hydraulic engineering constructions which are water carrying out channels, nondestructive control methods, a residual resource, modeling, and a technical condition

  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.

  The article deals with finding of the area of the central projection of the family of visible segments of a last set of sides of the controlled object. We offer to represent the central projection of the controlled object which is reflected on the camera's sensor, as a set of convex polygons in order to accelerate finding of the total area.

Keywords: polygons‘segments, cameras’ field of view, an algorithm for finding of polygon’s area

Work is devoted mathematical modelling of processes in the channel of the MHD-device with the conical axisymmetric form of a channel. The assumptions accepted at modelling are formulated. The mathematical description of a prototype system with usage of known laws of electrodynamics is conducted. The equations of components of density of current, a magnetic field and electromagnetic forces in the conical part of the channel of the observed device are defined. Adequacy of the developed model is confirm by results of computer simulation of processes in the channel of the device. Deductions about applicability of results of the given work are presented.

In this paper we study the dynamics of the local atomic structure of new nanostructured condensed material for for rechargeable current sources on the basis of 15mas.%V2O5/Fe/LiF nanocomposite within charge-discharge cycle on the basis of X-ray diffraction (XRD), X-ray absorption spectroscopy (XANES) and of computer simulation. The analysis of the experimental data obtained during the first charge cycle reveals the transformation of iron to more than 50% of iron fluoride (II) , Li ions intercalate into the structure of amorphous V2O5 forming LiVO2 compound.

  Structural changes in cumulative labor displace the purposes of social development and generate understanding of that the economy exists for the person, and people – the main value of modern society. The evolution of the term tracked in article the sociolabor relations, consideration of elements, levels and the purposes of the sociolabor relations, the characteristic of types of regulation of the sociolabor relations and an assessment of system of the sociolabor relations of Russia allowed to add definitions of the sociolabor relations by concept «the human capital» and to define system of the sociolabor relations of market economy as a complex of relationship concerning development and effective use of the human capital.

  Proposed to use a sensor based on surface acoustic wave (SAW), which represents a delay line with unidirectional interdigital transducers (IDT) for measuring the pressure in the liquid. Reflective IDT loaded by series connected inductor and two capacities. One of these capacities - this trimmer, and another - a membrane capacitor whose capacitance depends on the pressure. When the pressure changes of the membrane capacitance capacitor, which changes the reflectivity of the reflective IDT. The magnitude of changes in this ratio determines the pressure applied to the membrane capacity.

    The authors propose a method for determining the height of bus rollover to access body structure strength according to the Rules the United Nations Economic Commission for Europe № 66 (UNECE). Besides, it will allow to result in optimum value height of bus rollover with different dimensions. It is necessary to get more reliable information of body structure strength. For this purpose in procedure of tests it is suggested to enter the additional stage of calculation of the height of rollover before setting of transport vehicle on a rollover platform.
