Abstract. The content of chlorophylls and structural proteins of chloroplast membranes in winter wheat varieties of different resistance in the control and under the action of 7-day drought was studied. It was found that the more resistant varieties had an increased content of low molecular weight protective proteins in the control. During the drought, all varieties lost chlorophyll and basic structural proteins. This loss was greater in less resistant varieties. The relative content of low molecular weight protective proteins increased. Thus, it is shown that the protein content of 36, 21 and 16 kDa can be one of the molecular markers of drought resistance.
Keywords: Triticum aestivum L., winter wheat, structural proteins of the photosynthetic apparatus, pigments, drought.

Abstract. The prospects of using autonomous automatic solar orientation systems to increase the efficiency of small solar power stations are shown. A simple clear astronomical geographical model has been created to develop an algorithm for programming microcontrollers of autonomous trackers for an arbitrary point of the globe. The model is based on the geometric parameters of the Sun trajectory in the celestial sphere. The necessity of establishing the exact local solar time of the point of the power station location to achieve the maximum efficiency of its operation is shown.
Keywords: resource-saving energy, ground-based trackers, solar orientation systems.

Abstract. The article covers the use of bicomplex approach in the calculation of converters with multiple modulation used in autonomous renewable energy facilities. The proposed method in the hypercomplex representation leads to a reduction in information processing. The bicomplex representation method includes direct and inverse bicomplex transformation, which allows obtaining analytically complete solution for the analysis of a system with multiple modulation.

Abstract. Introduction. The growth in the amount of information available on the Internet is exponential. Filtering quality information from low-quality information is becoming increasingly difficult. Finding information from reliable sources is an important task. One of the high-quality sources of information is scientific research papers. The aim of the work is to build a system that can cluster scientific articles, taking into account its semantic properties, and compare clustering algorithms for this task. Results. The structure of scientific articles is analyzed and the features that should be taken into account when clustering articles by their textual semantic properties are determined. The process of cluster construction is described. The characteristics of the text part of the content are pre-formed using the neural network BERT. A system has been developed that processes the text part of a scientific article and builds clustering. Analysis of the developed system showed the advantages and disadvantages of clustering methods. Conclusions. The use of the developed system, which receives the characteristics of the text part of a scientific article, allows to comprehensively assess the relationship of scientific articles to each other, as well as to interpret these links.

https://doi.org/10.31174/SEND-NT2021-255IX32-09
Abstract: the peculiarities of conducting a rank analysis for the forecast of energy consumption of buildings and structures in Ukraine are considered. The optimization problems within the framework of optimization of cenoses with corresponding restrictions are formalized. It is proposed to use a technocoenological approach to select and rank activities within individual clusters. The advantage of the proposed approach for the selection of groups of measures to improve energy efficiency in buildings is the optimal reflection of the process of functioning of the objects of the technocenosis in the future, taking into account possible changes in technology, infrastruc- ture and resource use.

https://doi.org/10.31174/SEND-NT2021-255IX32-11
Abstract. The influence of such a social factor as a pandemic on the formation of demand for electric energy in Ukraine has been substantiated based on the analysis of literary sources. A significant impact of this factor on the consumption of electric energy in the country as a whole and on the distribution of consumption between sectors of the economy was revealed, which is confirmed by statistical data. In addition, it was noted that the tightening of quarantine measures affects the level of electricity consumption. There is a redistribution of consumption between consumer groups, especially between a part of office consumers and the household sector. It was also noted that the closure of public transport and other restrictions affecting the lifestyle of the population lead to characteristic changes in the consumption of electrical energy. A model has been developed for forecasting the demand for electrical energy, taking into account the factor of pandemics, based on expert assessments using the Bayesian approach.
Keywords: electricity demand, forecasting, power system, Bayesian method, Covid-19, expert opinion.
