Yermolov P. P. Ontology for the knowledge portal on radio engineering and telecommunication history [Електронний ресурс] / P. P. Yermolov // Telecommunication sciences. - 2013. - Vol. 4, no. 1. - С. 58-64. - Режим доступу: http://nbuv.gov.ua/UJRN/Telnau_2013_4_1_11 The article is devoted to ontology for the knowledge portal on radio engineering and telecommunication history development. We emphasize the ontology for basic portal which consists of eleven classes: "researchers", "researching techniques", "sources", "events", "organizations", "geographical location", "memorial object", "period", "scientific result", "branch of science" and "subject under investigation". The last three classes are represented as metanotions of portal subject ontology which include 19 first level subclasses and 60 second level subclasses. Inheritance and implication, as well as "class - data" dependences have been determined on the base of classes and subclasses. Thirty most actual associative dependences have been emphasized. The division of large sources (monographs and reviews) into smaller fragments and organization of subclass "quotations" in order to simplify the process of ontology development and to realize the most relevant search are proposed. Set theory tools and "two - level" concept of science and technology historiography as a metascience have been used in the process of formalization. | ||

Yermolov P. V. Age and geodynamics of central Kazakhstan carbon ore copper provinces [Електронний ресурс] / P. V. Yermolov, V. S. Portnov, D. K. Makat // Науковий вісник Національного гірничого університету. - 2017. - № 6. - С. 5-15. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2017_6_3 Purpose. To evaluate geodynamic processes of copper-ore deposits of the central and south-eastern regions of Kazakhstan which are spatially separated and different in genesis. Methodology. We use the new U-Pb (zircon), Re-Os (molybdenite) dating and older K-Ar (biotite) data obtained from the use of the conditional analysis by biotite (K2O >> 7 %) only. Findings. Based on the latest dating of rocks and ores of copper-porphyry deposits of Central Kazakhstan and Western Zhongar (China), a new model of the emergence and development of the copper-ore province is proposed. Originality. A model of the origin and development of the Central Kazakhstan copper-ore province, uniting the fields of different origin, age and ore potential in a single ore-magmatic system is developed. The model of porphyry copper deposit formation (accumulation-transportation - sag) perfectly explains the different genesis of the Central Kazakhstan coeval deposits. Practical value. Within the Central Kazakhstan copper-ore province is a priority object for a detailed study, based on the fact that according to statistics, about 85 % of copper-porphyry, and 100 % of copper-skarn ores occur either in magmatic rocks or in contact to them. | ||
