In this paper, a new simple and accurate hybrid table/analytical model of the MOSFET drain current based on the interpolation of table parameters is proposed. This new hybrid table model has an accuracy similar to the pure table models but requires no complex parameter extraction. The drain current in the hybrid model is calculated as the product of the analytical model current and the correction factor approximated by two-dimensional series.

Briefly discussed the theoretical model of the spectrum of RR intervals and its changes depending on the processes taking place. Made a device for measuring cardiointervalogramms (CIG). Obtained from the renting of data, of varying duration and frequency shall be recorded for further processing. The analysis revealed that the resulting spectrum satisfies the conditions considered in the theoretical model, and can be further analyzed with fractal characteristics. Such an analysis is of great importance in the diagnosis of the patient directly to the duration of the therapeutic procedure for the optimization of both time and intensity exerted influence.

  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.

  We propose a model describing the motion of the wave of viruses inside and outside of living matter. It is shown that the Schrodinger equation can be used in the analysis of movement of the virus, as a physical material object in physical space. We calculated the de Broglie wavelength of the virus. The mechanism of viral diseases is shown as an interaction of genetic apparatus of human cells with the field structure of viruses. The concept of information-wave virus is given. The results of studies on patients with the use of information-wave of viruses, generated by a special generator of digital codes, are given. It is shown that the reliability of the mechanism of cell damage by wave digital information and viruses on the basis of vegetative resonance test. The reliability of the mechanism of cell damage by information-wave digital viruses is shown with the use vegetative resonance test. The conclusion that the suppression of viruses can be realized with the use of radiation from a special generator of numerical codes has been made.

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

"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. "
