A finite element solution based on equevalent elements is proposed for the static and dynamic analysis of tallhigh tensioned cable antennas. To reduce high number of degrees of freedom in space frame body of a structure, a simple equivalent beam element is defined for each simulative substructure. This numerical procedure is applicable to analyze complex three dimensional assemblies of substruc...
The application of the latest digital technologies changes the ways of thinking of entrepreneurial behaviour and motivation of decision-making, principles of organization of their functioning, so the purpose of work is to form a model of achieving a balanced balance between economic efficiency and environmental and social responsibility of the digitized enterprise, determining the scientific ba...
Amorphous GeOx/SiO2 multilayers (1<x<2) were prepared by successive evaporation of GeO2 and SiO2 powders onto the Si substrates maintained at 100°C. Structural study by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared-absorption (FTIR) spectrometry, and transmission electron microscopy (TEM) was carried out. These techniques allowed us to follow the structural evolution, and...
COVID-19 is a novel coronavirus with an outbreak of unusual viral pneumonia in Wuhan, China, and then pandemic. Based on its phylogenetic relationships and genomic structures the COVID-19 belongs to genera Betacoronavirus. Human Betacoronaviruses (SARS-CoV-2, SARS-CoV, and MERS-CoV) have many similarities, but also have differences in their genomic and phenotypic structure that can influence th...
