    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 application of multielement piezoelectric transducers for ultrasonic testing of high-speed railway tracks

    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.

  • Developing of the algorithm of maximum flow of minimum cost finding in a fuzzy dynamic network

    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.
