Foreign securities markets and securities investment funds developed relatively early, in the 1960s, researchers have put forward many indicators and models to evaluate fund performance from different angles and aspects, includes T-M model, H-M model, three factor model and improved four factor model. As the most mature country in the world, the United States has done a lot of empirical research on fund performance evaluation. Most of the studies show that the fund can not significantly overcome the market due to the influence of many factors such as stock selection ability and timing ability. On the basis of screening all kinds of international research results, combined with the actual situation of domestic fund market, this paper selects five indexes, including net return rate, sharp index, market risk, timing ability and stock selection ability, to establish the corresponding mathematical model, and uses the method of cluster analysis and factor analysis to evaluate the performance of fund, and the model is tested and analyzed. The experimental results show that the method proposed in this paper has good evaluation performance.","PeriodicalId":201497,"journal":{"name":"2020 International Signal Processing, Communications and Engineering Management Conference (ISPCEM)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124137128","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}

Moreover, in the context of the global coronavirus epidemic prevention and control, media big data has different characteristics and missions. The scientific data platform, tool integration, scientific research process and international cooperation proposed in this article are implemented in four main lines of international cooperation for the implementation of ideas and technical methods in the field of media big data science for epidemic prevention and emergency, to achieve effective data management and analysis to improve the efficiency of scientific discovery. For cyber infrastructure research, preliminary research needs to build a digital, data-based, and intelligent cyber infrastructure framework and emergency response measures for disease prevention, psychological comfort, and material security. Based on the concept of \"Data-Method-Model-System-Standard\", the research overall design framework of MEP (media big data for epidemic prevention) is generated, and the research results are intended to help the epidemic prevention ecological layout of the media big data.

This paper focuses on experiments on capacitors, electric field strength and particle performance, magnetic field strength and particle performance, and radio waves and electromagnetic fields. These four online laboratory experiments explore capacitors, electric fields, magnetic fields, and EM waves, respectively. The purpose of this report is to convey the information compiled as a result of this work. The article accesses the online applet used from https://phet.colorado.edu/en/simulation of Physics Education Technology (PhET) and conducts experiments under the environment of installing Java script. Through experiments, the understanding and knowledge of related topics are effectively enhanced, thereby benefiting students. It verified the proportional relationship between stored charge, energy and capacitance, summarized the behavior of particles under electric and magnetic fields, and verified that high-frequency electrons produce short wavelengths, while strong electric fields cause strong forces applied to the electrons.","PeriodicalId":201497,"journal":{"name":"2020 International Signal Processing, Communications and Engineering Management Conference (ISPCEM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130750128","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 paper intends to divide further China’s provinces and cities into consumption-led areas, moderate areas, and investment-led areas. Then this paper adopts the time-varying parameter factor-augmented vector autoregression (TVP-FAVAR) model to conduct a theoretical analysis of macroeconomic response under China’s economic policy uncertainty. Using the transmission mechanism of interest rate channel, credit channel, and exchange rate channel, we predict that the increase in policy uncertainty will have a more significant negative impact on regions with a low proportion of consumption, manifested in a higher degree of decline in consumption, investment, and output. However, the price level is significantly consistent across regions. As for the nonlinear issue, as China’s economic environment changes, major economic indicators in various regions have shown obvious time-varying characteristics.","PeriodicalId":201497,"journal":{"name":"2020 International Signal Processing, Communications and Engineering Management Conference (ISPCEM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131405541","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}

Supposing the three fictional dragons were still alive, we build the DA model to analyze dragons. Firstly, we refer to Richards model—one of the most common model of creature size, to describe dragon’s body features in accordance with volume. Then in order to conduct fitting, we use the data of tyrannosaurus rex and the formula from another paper, which describes the relationship between femoral girth and body weight, finally we get the volume function. Secondly, when building the energy model, based on the energy budget equation, we decide to apply large bird’s energy model to our study and add the special activity energy to explain dragon’s ability to breath fire. Then we refer to the basal metabolic rate and active metabolic rate of super-large birds to calculate the energy of dragons. Finally, we get the calorie intake of dragons at different ages. Thirdly, for the characteristics, we assume that dragons can fly (even long distances), breath fire, and resist trauma. The mechanisms of flight and fire breathing are relative to energy metabolism. And we assume that dragon’s ability to resist trauma is related to the rate of cell proliferation. Then we build the cell growth model for this area’s research.","PeriodicalId":201497,"journal":{"name":"2020 International Signal Processing, Communications and Engineering Management Conference (ISPCEM)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131441259","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}
