The modern concepts review about the change in the ratio of free and bound water in biological liquids of patients shows the dependence of the dielectric constant of samples from patients and effectiveness of drugs. The requirements to the design of microwave sensors designed for use in devices operative diagnostics. The most effective quarter-wave resonator transducers with coaxial the measuring aperture were shown. Ref. 41 items.

A method for bit rate control in the processing of P-frames in the video sequence. Since the luminance component has a greater payload than the color difference block, to conduct selection of proposed threshold values and quality factors for YCrCb components so as to result in a luminance component has been compressed with higher quality than chrominance. images in real time.

Decision making processes in general and the problem of inventory management in particular are important for modern organizations. They are one of the most common classes of problem of operations research. There are many methods for these tasks, but one of the main methods are Data Mining. The paper was considered creating mathematical models of such problem. Таb.1. Fig.2.Ref.: 4 items.

In this article the using of nonequilibrium positional coding as the functional conversion for number with the embedde information is considered. The method of steganographic coding with masking of structural steganographic redundancy is developed. On a basis of the formulated rule the steganographic system for one bit of the hidden information embedding of on a line item of a high element of nonequilibrium positional number is designed. On an example process of embedding and extraction of the built-in information with simultaneous reconstruction of the initial nonequilibrium positional number is shown. Tab. 1. Fig. 2.

The models of the metric evaluation of students, scientists, teachers, departments, science and university education to create kiberservisov accurate monitoring and management of resources and production processes in order to achieve the sought-after market product quality. Questions of scale kiberservisov management in relation to high school in order to substantially reduce public expenditure on administrative staff, improve the efficiency of scientific and educational processes through the complete eradication of corruption, consolidation of universities, cyber-stimulation design scientists and professors, creating a market demanded products.

We study a balanced layout problem of homogeneous circular cylinders in the given container that has cylindrical, parabolic or truncated conical shape. Mathematical models for three problems are constructed in the form of nonlinear programming problems, using phi-functions. We propose the efficient algorithms, involving the multistart method, an algorithm for constructing a set of feasible starting points, IPOPT and Shores r-algorithm to solve nonlinear programming problems. We present a number of computational experiments for benchmark instances. Fig. 6. Ref.: 10 items

In this paper we propose to combine several technologies that provide higher accuracy results of determining the current position of the mobile object. To demonstrate this approach was proposed a prototype system based on the Android OS with iBeacon and accelerometer. Experimental results shows the improved positioning accuracy compared with each technology separately. Key words: localization, navigation, mobile objects. Fig. 9. Ref.: 6 items.
