  The superposition conception of endogenous factors influence on the hem lymphatic occupancy in the organism vascular system is presented. The main influence factors creating the wave modulation on the pulse blood and lymph flows in the vessels and liquid’s moving in the around tissues are considered in the physical model. On the basis of the model is justified hemodynamic functional test with dosed compression effects on local areas of the body, in which the reaction is analyzed for changes in the spectrum of signals related to the changes exhibited by volume-dynamic changes in the vessels. Shows the functional scheme of the formation of the wave changes hem lymphatic, allowing planning of the study.

  Now nanotechnologies are one of perspective methods of diagnostics in medical practice. Nanoparticles can be used as contrast agents for medical ultrasonic introscopy due to their adhesion to tumor cells and bacteria. The mathematical model of the laser excitation of acoustic signals in a liquid medium with the presence of the nanotubes was developed and numerically studied. Increasing of the level of photo acoustic signal was shown.

Keywords: Opt acoustic effect, nanotubes, and model

The state of surface water in such industrial cities of the Rostov region, as Belaya Kalitva, Donetsk, Kamensk-Shakhtinskiy. Identified the main sources of their pollution and priority pollutants. Analysis of the concentrations of pollutants in R. Sowing. Donets river and its tributaries. It is established that the water management situation in the industrial cities remains unfavourable, and the level of water pollution is assessed as «dirty»

This paper describes application of different criteria for estimating parameters of traffic simulation. For comparison following methods were used: statistical methods for comparison of a flow and speed in control points of a network - analysis of variance (ANOVA), Theil's U-statistics; relationships between flow, density and speed; relationships between trip time and stop time with using two-fluid models of traffic flow. For this aim we also used concept of meta-model. In order to implement this method we need on the first step to create separately relationship between traffic flow parameters for observation and simulation data and then to estimate combined model. The paper included results of calculation  

Keywords: validation, traffic, simulation, flow, speed

"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. "

The paper focuses on one of possible approaches to decision support problem, which is based on multi-agent simulation modelling. Most decision support cases generally consist of a set of available alternatives definition, estimation and selection of the best one. When choosing a solution one needs to consider a large number of conflicting objectives and, thus, to estimate possible solutions on multiple criteria. Multi-agent resource conversion process model was developed on the basis of several approaches integration: simulation and situational modeling, expert and multi-agent systems, object-oriented approach. The multi-agent resource conversion process model was extended elements coalition. Apparatus of conflict modeling was extended communications. Creation and disintegration processes of coalition are starting structural and parametric changes in multi-agent resource conversion process model. Coalition multi agent model of resources conversion process was implemented in decision support system BPsim.

The main models of DNA computing are self-assembly of DNA and RDNA. Disadvantages of these models are low speed perform arithmetic operations, the high probability of errors of computing, and perform the calculation with only fixed-point numbers. In article is represented method of encoding numbers by DNA strands. Numbers can be encoded by any base initially. This method does not require to translate the number into a binary number system. Each number is encoded by digit with the DNA. As compared with known methods, the proposed method uses a shorter length of DNA strands. The proposed method can increase speed encoding of numbers, improve the accuracy of the calculations and to reduce errors in the formation of the encoded data. In article is represented also the operations to perform arithmetic operations. The use of the proposed method of encoding numbers and proposed operations over DNA allows to increase speed of computation, and perform calculations not only with fixed-point numbers and floating-point numbers.

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.
