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.

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.

The paper is devoted to developing an approach to solving the problem of structure identification of layered minerals of the kaolinite group by the Rietveld method. The calculations of the intensity of the diffracted X-ray radiation are performed for the koalinit samples obtained from different fields. Qualitative agreement between calculated and experimental results has managed the solution of the identification problem for the kaolinite unit cell Glukhovtsy deposit. The obtained results indicate the possibility of identifying the features of the crystal structure of layered minerals by direct calculation of diffraction patterns.

  In article the information system of the MANAGEMENT information system is represented as the three-level model constructed by a principle of cascade maintenance. Problems of delays of the supply with information, formations arising at the expense of delays and data transmission are considered. The mathematical model of system intended for optimization of maintenance on parameter of delays, on the basis of priorities of processes of formation and an information transfer is developed.

This article describes an approach to create a model based on neural network for use in photoplethysmography. Using this model the development of a method for measuring blood pressure in the distal vessels. Such an approach allows for comfortable removal of diagnostic parameters for the need for long-term testing. These methods can be used to analyze the state of the human operator, and in particular, the driver at pre-shift control for skrinningovyh surveys.

"In this article the problem of the growing number of accidents involving young drivers, which is mostly not the lack of driving skills, and lack of understanding of the consequences that entails a violation of traffic rules and to re-evaluate their own capabilities and the capabilities of the vehicle. Analyzed the topic and watch the development of information ""model program for drivers in the category."" As the car - it is a source of increased danger, therefore, a priority must be driving schools driving instruction or training of candidates for the driving test, and the education of safe driving. To this end, the article on the basis of ""model program for drivers in the category"" work program has been drawn up with the increased number of hours of both theoretical and practical courses that best meets the requirements of initial professional education of the Russian Federation for the profession ""by the driver of category B ""for the professional skills and knowledge of the driver. The proposed training program has been used to train candidates for the drivers of one of the driving schools of Tsimlyansk. "
