In order to improve techniques of minimally invasive total knee arthroplasty (IEAC) based on anatomical studies, we have developed a mathematical model and a computer program IEAC preoperative planning that takes into account the anthropometric data of the patient (body type, size patellar index Insall-Salvati), type and size of prosthesis and allows to calculate minimal incision and maximum elongation wound during surgery. Use of this software improves the accuracy of the planning and preparation of surgery, to improve the accuracy of implantation of the prosthesis.

We propose a method for cooling the condenser compression refrigerator, including the use of melt water wetting the surface of the water condenser. The water is directed into the groove in the middle part of which is the tube condenser coil, and the water flows by gravity to the tribes of the inclined groove, wetting the surface of the trough and tube condenser. Remains of meltwater routed to the tank on the compressor.

Work is connected with the synthesis of information behavior of groups of autonomous intelligent agents of biomedical research, and machine learning methods to ensure the reliability of the forecast increase in their behavior using multi-agent systems based on the use of bionic principles, methods and models of swarm intelligence. Developed multi-agent system simulates the behavior of groups of autonomous intelligent agents developed methods to meet the proposed criteria of reliability, differing form the structure of the system and developed a set of specialized agents that provides the capability to model a group of biomedical robotics using autonomous intelligent agents. Classifier of stabilographic signals on the basis of Parzen method was developed. These data indicate that the auxiliary symptoms resulting from multidimensional scaling much more informative initial attributes.

The requirements to be met by a data acquisition system in terms of each of the problems to be solved. Presented electric concept developed biopotential amplifier with a total gain of 2000. The theoretical model of the spectrum of RR intervals and changes depending on the running processes. The analysis revealed that the resulting spectrum satisfies the conditions considered in the theoretical model, and can be further analyzed with fractal characteristics.

In this paper we consider the application of digital signal processing techniques to clean them from interference and to present in a special basis, which allows the detection of events related to the manifestation of the functioning of a functional system in health and disease. Implemented mathematical foundation and rapid synthesis methods for converting the signals used in electrophysiology based on the discrete wavelet and Gabor transforms. Filter synthesis using Filter Desing ToolBox package MatLab was observed.

Seed damage has a negative impact on the subsequent development of the plant, its yield, and generally on the economic efficiency of grain production. Main percentage of the grains injury occurs in the post-harvest processes, particularly in the grain cleaning. One way of solving this aim is reducing of macro and micro damage of seeds by using of the new polymeric materials. Researches have been conducted to reduce the micro and macro of injury barley seeds (feed material) through the use of new sieves made of polymeric materials UHMW PE for agricultural machinery.
