We have presented an analysis of hardware designs for preparation and distribution of animal foods and also developed the economical and the mathematical model of the process of preparation and distribution of food. We have developed a constructive-technological scheme of distribution chopper and a theoretical justification of the parameters of the distribution chopper
We have offered a constructive flow sheet of a root cleaner. Theoretical and experimental studies of roots purification process have been performed. We have also substantiated the main structural and regime pa-rameters of the proposed cleaner
The article discusses the relevance of the development of a mathematical model of threats and an intruder model which has been expressed in formalization of the process of finding vulnerabilities in information systems data at all stages of interaction between users and web-based applications, starting from user authentication procedures
The article describes a development of the mathematical model for managing access rights affecting the assessment of the effectiveness of the integrated systems of protection with selection factors, as well as groups of factors affecting the system security policy. The model works due to forming a binary expression which would lead to either a zero value or the unit, or not significant value. Next, we have control comparisons and analysis of the values that provides an expert decision about blocking the access rights or not. This system is adaptive and able to evolve by adding various factors and expansion of expert decisions
Thispaper presents atheoretical justification forthe process of cutting the stemsmulti functional versatile new type of cutting system
This article presents the possibility of modernization of grain harvesters, reapers, aimed to simplify their struc-tures and reduction of energy intensity of the process of harvesting grain crops. The article reflects the results of comparative experiments of work of a combine in different modes
The article presents the design of hand mowers with cutter, consisting of the rotating screw and stationary segments. It also shows the results of experimental studies to determine the rational angle turns of spiral screw
The article deals with improving the reliability of data collection and storage of historical data. Investigated the reliability of collecting historical information, the technique, allowing on the basis of general logical and probabilistic methods to identify the most important elements to increase the reliability of which will sig-nificantly increase the reliability of the whole system
