To this end, we estimate linear regression models using data from the Mobility Survey, which consists of observational data on transport mode choice. Based on the results obtained through the conducted questionnaire surveys, many influencing factors on the choice of transport were studied through the correlation equation. Using the applied Logit model, the maximum likelihood method was used for the selection of the mode of movement in the evaluation of the objective function of passengers in inter-address movement. The objective function in the choice of which of the available alternatives was preferred by each passenger in moving to the intended destination was evaluated. The important variable attributes of the alternatives that influence the choice of inter-destination transportation means of passengers are identified. The choice model represents the probability of choosing each alternative through the calculated Logit model. A linear regression equation was developed using the coefficients obtained on the basis of the correlation matrix. The results of the regression model were obtained as part of the interaction of the transport choices of passengers.","PeriodicalId":481579,"journal":{"name":"Journal of science and innovative development","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135165860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a selection of components of the mixture, we’d studied its morphology and thermal properties. It was found that thermal stability (initial temperature) of the composition decreases as the amount of gelatin increases due to degradation of gelatin. In the temperature range of 400-500 ºC, the maximum rate of destruction of the graft copolymer increases significantly with higher gelatin content. Samples having identical composition were selected using a Brabender plastograph and a mechanical mixer; and when taken at different rates, the morphological structure of the samples was determined to depend on their mixing rate. The morphological structure was found to show that increased speed leads to effective reaction of two components and crushing of particles into smaller ones.","PeriodicalId":481579,"journal":{"name":"Journal of science and innovative development","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135165862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This raw material, low in phosphorus and rich in carbonate and chlorine, is not suitable for acid treatment. To obtain high-quality phosphate fertilizers from raw materials, it must first be enriched. At the Kyzylkum Phosphate Plant, multi-stage enrichment is carried out: crushing, dry enrichment, chlorine removal, sintering to remove CO2. One of the promising areas for the processing of phosphate raw materials of this type is heat treatment, based on the destruction of the crystalline structure of the mineral, which is indigestible by plants, during thermal activation. The work is aimed at obtaining a thermophosphate fertilizer, which is insoluble in water at different temperatures and times in optimal proportions with sodium chloride, sulfate, potassium carbonate, chloride, sulfate salts, sylvinite and silicon oxide/coal, which are more active. The regularity of the influence of temperature and weight ratios of the mineralized mass from the fractions of phosphorite ore of the Central Kyzylkum: silicon oxide/coal: sodium salts on the assimilable phosphorus in thermophosphate fertilizer is shown, as well as the fact that the digestibility of phosphorite ore of the II-layer is higher than that of other raw materials. An increase in the content of assimilable phosphorus in synthesized primary phosphorus thermophosphate fertilizers with an increase in temperature and time is substantiated at equal weight ratios of phosphorite ore of the II layer: silicon oxide/coal: sodium salt.","PeriodicalId":481579,"journal":{"name":"Journal of science and innovative development","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135165864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to establish the possibility of using the synthetic inertia controller of wind turbines to reduce the amplitudes of frequency fluctuations in transient conditions. One consequence of integrating a large number of wind farms is to reduce the amount of kinetic energy (inertia) available to operate the system. If the system inertia becomes too low, it can compromise frequency stability when large generating units fail. The smaller the moment of inertia in the system, the greater the frequency fluctuations occur after the active power balance is disturbed. A regulator of synthetic inertia of a wind power plant has been obtained, which makes it possible to reduce frequency dips during transient conditions. Recommendations are made regarding the choice of gain factors for the inertia controller. A control model for wind turbines with a synthetic inertia controller is presented. On the example of a test circuit of an electric power system, modeling of disturbances in the form of a load surge and a short circuit was carried out. As a result, the characteristics of the change in the frequency of the electric power system in the absence and presence of a wind power plant are given.","PeriodicalId":481579,"journal":{"name":"Journal of science and innovative development","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135165713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subject of the research is the laws of propagation of physical fields used in geophysical science. The aim of the research is to develop a series of laboratory and practical activities on geophysical methods in order to show the processes of physical field propagation in the geological environment, to students. The research was also focused on a review of the global experience in using digital (virtual) laboratories in educational practice for teaching natural and engineering sciences, particularly, in geophysics. As a result of the review of the data on geophysics, we have developed algorithms for calculating and visualizing the processes of physical field propagation. These algorithms were developed for such sections of geophysics as seismic exploration, seismology, electrical-, magnetic- and gravity exploration. Ultimately, the algorithms have enabled implementing of a platform on which laboratory units which incorporate such sections as seismic exploration and seismology. The analysis of the students’ feedback confirmed effectiveness of the program, contributing to the development of critical thinking skills, self-discipline, and responsibility.
