Modeling of bioenergy impact on food security of EU countries

Ensuring the energy and food independence of each state will not only remain important but that its importance will continue to grow given the constant need for the state to properly guarantee the basic needs of the population. However, the rapid development of bioenergy is a potential precondition for the fuel and food conflict over agricultural raw materials. The article examines the relationship between food safety indices and the overall share of energy from renewable sources and bioenergy production in 13 European countries. The main factors characterizing the food security of these countries for the period from 2012 to 2018 are identified. Statistical methods of correlation analysis are used to determine the links between the outlined factors. It is studied that in most countries the prosperity of the bioenergy sector of agricultural enterprises does not affect the main indices of food security. In 5 countries (Poland, Germany, Norway, Spain, the Czech Republic) correlations were found, but for the most part, they are direct. It means that large values of one variable are associated with large values of the other, in other words with increasing the share of bioenergy production and overall share of energy from renewable sources, food safety indices also increase

Earth station antenna posts, created by design office "Promin"

In the process of development of mobile telecommunication systems a specific aggregate, namely, an antenna post, has been constructed. The antenna post comprises feed, receive-transmit, control, life supporting, guidance and energy supply subsystems. Depending on purpose tasks the number of subsystems is changed. Ternopil State Design Office "Promin" in cooperation with the Laboratory of Antennas and Telecommunications of the National Technical University of Ukraine "KPI" have created and tested antenna posts for earth stations of different types in C- and Ku- band. The design is based on a modified dual reflector Cassegrain antenna. To meet the INTEL-SAT/EUTELSAT requirements concerning with radiation patterns at a principal and cross polarization the synthesis of amplitude and phase field distribution at aperture of the main reflector has been realized

Full-band frequency-integrated antenna monitoring system

The article presents full-band frequency-integrated antenna monitoring system. Module optimization of full-band structures is conducted on the basis of the use of different type antennas for some separate basic frequency ranges (modules), which in the process of the integration create the integrated full-band system with the maximum factor of the use of effective capacity
