The comparison of the quality of the processing of surfaces of shafts made of various materials with cold and hot deformation in the repair of worn-out parts of agricultural machinery has been made in the article. The technique of the experiments was proposed. The effect of the treatment regimes on the quality of the surface layer (surface roughness) of the details was examined
In the article, the structurally functional method of the search of the defects in the segment of the computer network is considered. The basis of this method makes: the structurally functional model of a network; the table of malfunctions; the vector of checks with the obvious address of the knot of the network
The article deals with the models and the methods of the market of the proposed sub-systems and equipment, based on the analysis of the requirements for security to choose the best solution for the synthesis of the integrated security system
The results of the research project with the wind tur-bine layout of an optimal aerodynamic configuration of the rotor are given in this article
The article is devoted to the researching of complete observability of time-varying perturbed differential-algebraic system. The method of cascade splitting of the original space to the subspace is used. The formula for finding the state vector is derived. The relations between input and output functions are obtained
In the article we have represented the following items: the sphere of utilization of the ozone in apiculture, the mathematical model which establishes connection between level of development of bee families and parameters of in-hive microclimate and allows to theoretically substantiate the spring development up to 35 % as a result of ozone treatment; the results of experimental investigations of the influence of ozone treatment parameters on the spring increasing of bee families; feasibility study of ozone generators' application in apiculture; recommendation for application of the results of investigation are given
In the article we have represented the following items: heating model of discharge device of the ozone gen-erator which allows to examine the transient process and establishes dependence of heating time constant of the dielectric barriers on constructive parameters of discharge device. The rational parameters of design of the ozone generator for in-hive treatment of the bee families are defined; recommendations for utilization of the results of investigations are given
Identification of the processes of knowledge manage-ment technical service companies was done. A general model of field subject was presented in the form of ontology. Software ontological modeling was re-viewed
Results of rheological investigations of
protein-chitosan complex obtained from milk-whey system with different ratio of components are demon-strated. Portable consistometer to determine elastic behavior of the samples is designed.
Optimal protein-chitosan complex, close in
rheological parameters to curd cheese 18% fat, is detected
In this article, contact conditions are investigated at superficial plastic deformation by running-in rollers of details by a method of load cells
