  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.

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.

The article gets application multi-element piezoelectric transducers for ultrasonic high-speed flaw  detection on railway tracks. The processing algorithm of echo-signals from multi-element piezoelectric transducers was offered to get additional information about defect location to apply solution considering risk level more validly and to increase crack detection probability. The obtained algorithm was realized as software package. A set of experiments was completed for fourth-elements inclined piezoelectric transducer on a standard pattern for various positions to verify the processing algorithm. The experiment has shown that the echo-signals behavior allows to use the obtained algorithm for multi-element transducers at the high-speed flaw detection. Also it has emerged that the echo-signal shape at one element of piezoelectric transducer strongly depends on refracting prism geometry and relation position elements on prism.

The article considers the problem of maximum flow of minimum cost finding in fuzzy dynamic transportation network. The relevance of the problem is in its wide practical application on the rail, air, sea and other roads in finding of routes of minimum cost. The feature of the problem statement is that fuzzy nature of the network parameters, such as arc capacities and costs is taken into account. It allows us to make decisions more sensitive to environmental changes. The dependence of network parameters from flow departure is also considered, that allows to introduce the notion "dynamic" network as opposed to "stationary-dynamic", examined in the literature. The algorithm for solving the described problem in fuzzy conditions is proposed. To illustrate the algorithm a numerical example is presented.

Keywords: dynamic network, maximum flow of minimum cost, fuzzy numbers, arc capacity, transit time

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.

  Depressed calcaneus fractures tend to reveal comminuted nature, and are accompanied by apparent  oedema of soft tissues in the ankle joint and foot zones. Rigidity of calcaneus fracture fixation and ability of an early performance of graduated weight bearing by a certain extremity depend on the precision grade of clamp location in the main splinter body. Presently, this problem is solved by means of an electric-optical image converter application. A method, and an appliance for its practical implementation are being offered, which will provide for an increased precision of a crew/wire installation into the calcaneus, with a simultaneous reduction of radiation exposure on both surgeon and patient. 35 patients with depressed calcaneus fracture were operated according to this method; a therapy result for the period from 6 months to 2.5 years has been made for 8 thereof. The algorithm of therapy did not foresee the external immobilization, the graduated weight bearing commenced after 1.5 months, and the complete weight bearing started after 2.5 months. Redislocation of splinters has not been noticed in any of the cases considered. The appliance offered ensures a high quality of surgical therapy.
