  • Psichostabilograph - functional unit of psychodiagnostic human

      As a functional diagnosis of behavioral disorders are reflected in the proposed form of mental disorder "Method of assessment of mental characteristics based on the functional state of man" (patent number 2,353,287), which is implemented by LLC "PSYCHOGRAPH" (Taganrog) in the computer program "Program psihostabilometric test man" (certificate number 2011616719). Psihostabilometrich testing program tailored to the person stabiloanalizator with biofeedback "Stabilan-01" manufactured by ZAO "OKB "RITM"(Taganrog), and makes him its modification" Psihostabilograf". The method of testing the dynamic performance psihostabilometric person allows you to automatically hardware-software complex for 3-5 minutes with some validity, reliability and scale to evaluate conditional psiсhofunktsional normal condition of the patient and the degree of compliance for each subsequent survey.

  • Nested metagraphs as models of complex objects

    "The concept of the nested metagraph as the model of a complex object with different levels of generalization is introduced. It is shown that the nested metagraphs reflect the general system concept for description of complex objects with synergistic effect. This approach enables moving from the set-theoretic description of complex objects to their algebraic-theoretic description, thus increasing the model adequacy to real-life objects. The application of the nested metagraphs, in particular to business-intelligence and semantic search is considered. "

    Keywords: nested metagraphs, complex object, hyperedge as the essence, business analysis, a semantic network

  • About the development of the methodology of calculating the cadastral value of the land plots of large industrial enterprises

      The issues of improvement of state cadastral valuation of land plots, which are occupied by industrial enterprises, are investigated in the article «About the development of the methodology of calculating the cadastral value of the land plots of large industrial enterprises». The analysis of the possibilities of application of methods of individual assessment for the valuation of such land plots and the delineation of the concepts of cadastral and market value were made.

  • Thermoactivation current spectroscopy of electrically active centres in epitaxial monocrystalline films of (TmBi)3(FeGa)5O12:Ca2+ ferrite-garnet

    The spectra of thermally stimulated conduction currents (TSCC) in (TmBi)3(FeGa)5O12:Ca2+ ferrite-garnet films have been investigated with the purpose to reveal electrically active centres. The samples were fabricated by liquid phase epitaxy (LPE) from melt solution on the Gd3Ga5O12substrates with the crystallographic orientation (111) with the use of Bi-containing flux (without Pb). Increasing the concentration of Ca2+ions in the films were realised by increasing the concentration of CaO in the melt solution. The obtained films contained Ca2+ ions from 0,03 f.u to 0,1 f.u. With the help of standard thermoactivation current spectroscopy the spectra of the initial samples and samples subjected to ultraviolet radiation and negative corona discharge were obtained. The characteristic parameters of electrically active defects were calculated.

    Keywords: thermally induced electrical current, ferrite garnet films, electrically active centres, deep-level capture, charge compensation, Ca- doping, ТСТП-spectra, temperature position

  • 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.

  • 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.

  • 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.
