In the article we present the results of theoretical and experimental researches of physic-mechanical proper-ties of seeds of vegetable cultures and their interaction with vibrating surfaces of working bodies of sowing devices. The general view of the laboratory installation developed by the authors of the article has been presented
The results of tribological researches on influence of friction on contact interaction of tobacco leaves with working bodies of the machines for their harvesting and further green leaf processing are presented. Coefficients of static and sliding friction are measured
Technological methods of grape and derived semi-products processing are considered in the article. Husks, seeds and cuticle of grape are the important source of BAS due the high content of essential substances. Salt of tartaric acid, CO2 – extracts, grape oil, resveratol, vegetative flour are produced from the grape husks
Since there are many alternatives to artificial intelligence systems, there is a need of assessment of the quality of mathematical models and systems of artificial intelligence that support these models. This work is aimed at studying and developing standard methods of using the database of UCI repository to assess the quality of mathematical models of systems of artificial intelligence. The aim of this work is the development of methods for assessment of the quality of mathematical models of artificial intelligence systems for the classification of animals by external evidence-based database of the UCI repository. The objectives are: systematization, consolidation and expansion of theoretical and practical knowledge in the discipline of Intellectual information systems and technologies; study of "Eidos" intelligent information system; solving the task with the use of "Eidos" intelligent information systems. The object of research is the "zoo" database of UCI repository. In the first Chapter there is an overview of the theory to the solution of the problem, identification of problems, the original data, tools and metrization scales. In the second Chapter of the work we present the solution of the task. In the conclusion, the results of the work have been made; the conclusions on the achievement of goals and objectives have been given
The article describes hardware and software specific issues of implementing augmented reality for improving user interface of visualization of a virtual object. It also defines possible future improvements of the subject
The object of studying was CMD-108 crusher. The aim of this scientific article is studying kinetic and dynamic parameters of crusher operating devices. As a tool of studying there were used methods of mathematic analysis, theoretic mechanics and physics. As a result of theoretic studies there were defined speeds of various points of the crusher operating devices as well as there were obtained the values of dynamic loads on them and given recommendations on optimization of the crusher operating conditions and its designs. There was also determined an optimum zone of the material crushing from the viewpoint of operating life of the hinged joints of movable jaw enabling to reduce to minimum dynamic impact components of the reactions of the supporting joints of the movable jaw which increases their operating life
