Applying data mining technology to enterprise management can provide more effective support for enterprise decision-making. In order to improve competitiveness in the fierce market competition, more and more enterprises pay more attention to the need of risk management and control. On the one hand, financial risk analysis can make early warning to ensure the continuous operation of enterprises and bring economic profits for enterprises; on the other hand, it can also avoid risks for investors. This paper takes small, medium and micro enterprises on the New Third Board as the research object and uses data mining technology to study the internal relationship between main financial ratios and enterprise bankruptcy risk. Through the application of association rules and apriori algorithm, this study found some indicators closely related to the bankruptcy risk of enterprises, including current ratio, quick ratio, ROA and cash ratio. When these ratios fall below a certain value, enterprises are more likely to get into financial trouble. Enterprises can timely evaluate their financial risks by focusing on related financial ratios, and build up a financial risk early warning index system, so as to promote their stable and long-term development.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129272153","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}

Through the analysis of their working principles and the verification of simulation experiments, the polar navigation algorithm based on grid navigation mechanical arrangement is proposed, the polar navigation scheme of the inertial navigation system with abscissa system is established, and the conversion relation of each navigation parameter in the inertial navigation system between the abscissa system and the traditional coordinate system is derived. By introducing the transverse earth coordinate system instead of the traditional earth coordinate system, the problem of the semi-analytical inertial navigation system mechanical arrangement method when working in polar region is solved.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126676667","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}

In order to take the illumination uniformity and the communication reliability into consideration, taking a 4m * 4m * 3m room as the model, four LED arrays are used as the indoor light source. First of all, through the formula calculation combining with the software simulation analysis obtained that the size of the 9x9 LED array can meet the indoor illumination needs; Secondly, analysis respectively from the distribution of illumination uniformity and reliability of the communication perspective, different layouts are obtained. Finally, in order to take the uniformity of the illumination distribution of VLC system and the reliability of communication into consideration, the system optimization model function f(L,i) is constructed by the standard deviation of the illumination of the indoor receiving plane and the average error rate of the receiving plane in the communication. When the minimum value of f(L,i) is reached, the receiving plane illumination uniformity requirements and communication bit error rate requirements can be guaranteed at the same time. At last, through the simulation the minimum value is obtained when L = 0.55 m and i = 0.01 m. The minimum value of the illumination of the receiving plane is 337.52lx, the maximum is 482.05lx, the uniformity is 76.97%, and the error rate is 2.81*10-7. The results show that the system can take into account the uniformity of indoor light distribution and the reliability of communication.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126349510","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 scheme realizes the privacy protection of the vehicle and the anonymous authentication of the vehicle and the server by introducing dynamic identity and dynamic key mechanism. At the same time, by constructing a temporary identity index database, the trusted center can track suspicious vehicles after the fact and meet the conditional anonymity requirements of vehicles. In addition, part of the private key of the vehicle in this solution will dynamically change with its temporary identity, which reduces the correlation between the vehicle’s real identity and the private key, and improves security. At the same time, in order to obtain high-efficiency authentication efficiency, the use of unparalleled linear pairing calculation effectively reduces the communication volume of information transmission and the verification overhead of the authentication center.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127824291","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}
