The notion of telerehabilitation is considered. The types of physical activity that are necessary to conduct a telerehabilitation are indicated. A method for carrying it out using wearable devices is proposed. It is proposed to use a smartphone, which includes an accelerometer and a gyroscope to determine the physical activity performed by the patient. A literature review of approaches to the recognition of physical activity types is given. An experiment to select such features for the classification of physical activity that would allow for high classification accuracy with minimal computational costs, regardless of the location of the smartphone on the human body is carried out. As a means of carrying out the experiment, the MATLAB environment was used. For the experiment an open data sets has been used, which contains data from the sensors of the smartphone.","PeriodicalId":261560,"journal":{"name":"2019 International Science and Technology Conference \"EastСonf\"","volume":"14 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120912888","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}

A boiler with a thermal capacity of 0.63 MW with a vortex combustion system efficiently operating on fuel from coal waste was designed, manufactured and tested.

The solution was obtained based on Fourier's variable separation method with involving the additional boundary conditions. The physical sense of the additional boundary conditions consists in complying with the original differential equation in the boundary point of the transverse space variable (in the conduit center). It is demonstrated that the proposed approach allows obtaining simple-form approximate analytical solutions with the accuracy being sufficient for engineering applications. Therefore, in the range of $mathbf{x}pmb{geq 0.01}$, the deviation between the obtained results and the accurate solution already in the fourth approximation is not higher than 3%. It is noted that considerable calculation differences occur in obtaining the accurate analytical solutions for small values of longitudinal coordinate.","PeriodicalId":261560,"journal":{"name":"2019 International Science and Technology Conference \"EastСonf\"","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114548116","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 approach largely allows satisfying the requirements for the implementation of known methods for monitoring the state of objects in the cloud computing environment.

The experts' poll is used when forecasting the use of forest plots on the lands of populated areas. The method of analogy is most widely used in the evaluation of medium-forming functions. The method based on extrapolation is widely used in the practice of forest management. These methods are “naive”. The forecast by models allows to “penetrate” the internal mechanism of ecosystems of forest lands, using established cause-effect relationships. The results of forecasting based on analytical models of annual runoff in forest-covered watersheds under different scenarios of forest management are presented. Algorithms of decision-making in the sphere of land relations on forest lands are considered; stages of forecasting: research, program and organizational.","PeriodicalId":261560,"journal":{"name":"2019 International Science and Technology Conference \"EastСonf\"","volume":"363 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134330191","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 aim and objectives of the study were stated. Comprehensive energy survey of boilers was carried out when combustion of biofuel mixture with a moisture content of 56.7%, mass fraction of sawdust was about 42%. Components of the heat balance and emissions were determined. Ash particle size distribution for the content of combustibles was carried out. Porous structure of coke particles was studied using an Autosorb-iQ-MP automatic analyzer by nitrogen adsorption. A verage diameter, specific surfaces and pore volumes were determined. It is shown that carbon particles carried away from the combustion chambers of boilers with the size of 0.25 mm and larger are a sorbent similar in properties to activated carbons. Therefore, it is advisable and technically possible to separate this fraction and then use it to clean wastewater and exhaust gases. State of the enclosing surfaces of the boilers was checked by thermovision inspection. Recommendations are elaborated to improve the energy and environmental performance of the surveyed boilers.","PeriodicalId":261560,"journal":{"name":"2019 International Science and Technology Conference \"EastСonf\"","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132858777","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}
