Description
The modern level of development of the industry requires creation of more difficult and high-precision systems of an electric actuator allowing executing precisely and correctly the given technological processes. As these devices, we may consider hybrid or cascade systems of an electric actuator. However, for creation of such devices we require new design approaches, or specification and improving of the existing theories and methods of design of classical systems. The main difficulty in calculation consists in determination of parameters of electromagnetic system. In this article, new approach is given in finding of electromagnetic parameters of components of an asynchronous controlled cascade electric actuator taking into account real geometry. This approach was formed during creation of the program complex, which is a part of a system of automatic design

Description
Approach to the design of system of automatic management of working organs of mechanotronic preparation-fillet equipment on the base of numerical automatic drive is considered in the article. Generalized structural scheme of management system by numerical automatic drive on the base of electromechanical stepping rotary indexing table is casted. Approximate model of numerical automatic drive was considered and impulse transition characteristics with different coefficients of PD-tuning controls were casted.

APPROACH TO SAFETY MANAGEMENT AT MECHANICAL ENGINEERING ENTERPRISES
DescriptionIn the article, approaches to the management existing at the present stage are considered, their merits and disadvantages are described. General scientific and special approaches to management are singled out. The system, functional and process approaches are described in more detail. The principles of E. Deming are considered. It is pointed out that the application of the above approaches to production management is limited only by the economic sphere of activity, while there is a prospect of using these approaches in the field of labor protection. The article substantiates a selection of the process approach as the most promising in the management of the labor safety management system and health protection of a machine-building enterprise

APPROACH TO MANAGEMENT PERSONNEL AT MECHANICAL ENGINEERING ENTERPRISES
DescriptionThe article considers the existing at the present stage of management approaches, describes their advantages and disadvantages. We have obtained scientific and special management approaches. Of all the approaches described in detail, we could highlight system, integration, dynamic, structural, functional and process approaches. It was indicated, that the use of the above approach to production management, as a whole, and the staff in particular - is limited to the economic sphere of activity, meanwhile, as there is a prospect of using these approaches in the field of labor protection. We also substantiate the choice process approach as the most promising in the management staff of mechanical engineering enterprise

FINDING AND RANKING KNOWLEDGE ON THE SEMANTIC WEB
DescriptionThe basis of Semantic Web technology is the possibility of joint construction of ontology and the formation of the dictionary without centralized control. All the information and the knowledge encoded in the ontology as semantic web-terms and the semantic web-documents. Swoogle helps software agents and knowledge engineers find Semantic Web knowledge encoded in RDF and OWL documents on the Web. Navigating such a Semantic Web on the Web is difficult due to the paucity of explicit hyperlinks beyond the namespaces in URIrefs and the few interdocument links like rdfs:seeAlso and owl:imports. In order to solve this issue, this paper proposes a novel Semantic Web navigation model providing additional navigation paths through Swoogle’s search services such as the Ontology Dictionary. Using this model, we have developed algorithms for ranking of Semantic Web objects at three levels of granularity: documents, terms and RDF graphs. The article focuses on the ranking at the document level, based on a rational search model, which emits the agent's behavior when navigating at the document level, and ranking on level terms, the value of which is determined by the number of their references in all documents
