  • A new approach to provide web accessibility for the blind users based on the enhance of navigational characteristics of web pages

    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.

  • Cognitive approach to the research of geopolitical processes in world regions and cognitive modeling of their development (On the example of the Black – Caspian Region)

      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.

    Keywords: World regions, geopolitical processes, modeling of the complicated systems, modeling of the geopolitical processes, cognitive modeling, the program’s system of the cognitive modeling, the Black Sea – Caspian Region, the Black Sea sub region, the Caucasus

  • Economic efficiency of phased development of dry ports

    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

  • Identification of the structural features of layered minerals by X-ray diffraction

    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.

  • Multicriteria decision making under risk based on the integration of multi-agent, evolutionary modeling and numerical methods

    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.

  • The integrated cognitive architectureof models of sicial systems

      The article deals with the scientific principles of modern cognitive modeling offered in foreign practice to combine already existing and new models in the future in the form of cognitive architectures. Our approach is based on the concept of a unified theory of cognition, described by Alan Newell, which offers the general provisions for cognitive models used in all areas. In the computer environment, the theory is realized in the form of cognitive architectures. Shown, cognitive architecture is a system integration of static and behavioral models, which provides a solid approach to modeling knowledge of social processes, from the empirical data to quantify the simulation  of results, from level of the neural description to system level, thus the cognitive model is scaled to higher level with preservation of qualitative properties, and as a platform for integration the storage of data serves. Formally described by the level of integration corresponds to the construction of integrated information environment that combines unified storage of data with appendices of analytics.
