AbstractThis paper presents an originally-developed system for design and optimization of AC-DC converters dedicated in particular to operation in distributed generation systems. The proposed procedure is based on a multi-objective discrete optimization and expert knowledge of electrical engineering, especially power electronics. The required accuracy of calculations is obtained by using the database with real components, while the parameters applied in calculations are based on parameters provided by the manufacturer. The paper presents the foundations and basic system properties, the design and optimization process, and selected optimization results, obtained with a fully functional prototype of the design and optimization system (DaOS).

Analysis of linguocultural aspect of temporal nominations is impossible without involving the problems of hrononymic lexics. Chrononyms is an important information resource of a certain linguaculture, some distinctive peculiarities of conceptual picture of the world. The aim of the experimental analysis is a complex examination of the linguacultural aspect of temporal nominations that function in Chinese and Turkish languages reflecting the concepts of the world. The research was based on the material of the novels “Imperial woman” by Pearl Buck and “Roxolana” by Pavlo Zagrebelniy. The analysis of recent scientific publications allowed us to come to the conclusion that the investigation of hrononymic lexics can involve different theoretical and practical principles. Being guided by the existing classifications of chrononyms (N. Podolskaya, M. Torchinsky, S. Remmer) the linguocultural features of the following types of temporal chrononymic lexical units were identified and studied in the research: georthonyms, dynastic chrononyms, tumultonyms, parsonyms and mensonyms. The results of the research demonstrate that not all lexical units of temporal denotation chosen from the above mentioned novels refer to the class of chrononyms. The group under investigation includes the following lexemes: nominations of the lunar calendar, nominations of the solar calendar, nominations of mixed calendar and temporal slots denoting day and night. The basic system of chronology in the linguiacultures under analysis is the dominance of the lunar calendar nominations (Chinese picture of the world — 51,0 %, Turkish — 40,4 %). In the analyzed works the nominations of the solar calendar are used less often in the Chinese picture of the world; the usage of this unit reaches 20 %, and this phenomenon is historically conditioned. Mixed calendar nominations (21 % of temporal units) are rather common, solar calendar nominations are refined by the monthly calendar; it can be explained by the fact that the Chinese mind is conservative towards the new temporal system. In the Turkish picture of the world 45 % of temporal vocabulary belongs to the solar calendar since in the sixteenth century only a lunar calendar operated in the Ottoman Empire. It should be mentioned that significant place in the temporal vocabulary of “Roxolana” is conditioned by the influence of the linguistic personality of the author, who was a Ukrainian.
