It is observed that the general NSFD method for PD systems may not result in numerical models for such systems that are dynamically consistent with respect to the conservation laws. This is illustrated through two examples, with one satisfying a direct conservation law and the other a generalized conservation law. Alternative NSFD schemes that are dynamically consistent with respect to the conservation laws are constructed for these examples using the general method for conservative systems.","PeriodicalId":19593,"journal":{"name":"Open Access Library Journal","volume":"46 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89953283","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}

{"title":"Research on PE Tutoring Service Strategy under the Background of New Curriculum Standard","authors":"Ying Tang, Xin Weng, Leijie Gong","doi":"10.4236/OALIB.1107366","DOIUrl":"https://doi.org/10.4236/OALIB.1107366","url":null,"abstract":"With the development of social economy, the implementation of the national fitness plan and people’s attention to their health, physical education has become a unique way of life. Tutoring institutions are educational institutions that provide “one-to-one” individual academic guidance for learners in their families or tutoring institutions. The emergence and development of tutoring institutions has its historical inevitability, which is closely related to the enhancement of social competition consciousness, the disadvantage of large class teaching, the lack of social and economic status of teachers and the educational concept of parents. The target range of physical education has been broadened. For children please sports tutoring is a very common social phenomenon, but this does not mean that only children need to please family tutoring, in a narrow sense, the main object of sports tutoring is for children (primary and middle school students) groups. With the continuous development of the society and the different needs of the members of the society, the target range of physical education has been expanded. In a broad sense, all the people who have sports training needs can ask for sports tutoring, therefore, sports tutoring is a kind of personalized sports education services in essence. At present, although the physical education institutions have obtained unprecedented development, but through the investigation found that physical education also has some problems, such as through non-standard publicity, random fees, tutoring quality is difficult to guarantee. The existence of these problems is not correct, driven by interests, internal management strategy is not in place, the idea of running a school of sports tutoring institutions is too profit-oriented. To solve these problems, PE tutors should pay attention to the content and ensure the quality; Reasonable publicity, create brand; Stabilizing teachers, strengthening training, expanding scale, strengthening marketing and so on. At present, whether the development needs of students can be taken as the ultimate starting point is an important factor affecting the survival and development of tutoring institutions. This paper adopts a variety of research methods such as literature method, interview method, questionnaire survey method and mathematical statistics method. All of these situations are the actual problems that all of us sports workers must face. Facing these problems, we must effectively solve the problems, in order to provide theoretical basis for the research of sports tutoring service strategy under the background of the new curriculum standard.","PeriodicalId":19593,"journal":{"name":"Open Access Library Journal","volume":"30 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80795162","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}

As a result, a growing number of foreign cosmetic companies have expanded their presence in China. By contrast, Chinese domestic cosmetics not only don’t have an edge in its home market, but also fail to go global. The reasons are manifold. But their translations are also very important. Guided by Skopos Theory, this thesis believes that translation is across-cultural communicative activity with a certain purpose. The skopos rule should be put on the top priority. Through the investigation of various translation examples, the author believes that Skopos Theory can be used to guide the translation of different Chinese cosmetic brand names. Besides, the author also holds that translation strategies should be different according to the purpose of translation. By doing so, the author hopes to transcend cultural differences and disagreements so as to make domestic cosmetic products more competitive in the international arena.","PeriodicalId":19593,"journal":{"name":"Open Access Library Journal","volume":"117 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79337427","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}

Three treatment machines were modeled in our TPS with a different value of dynamic minimum leaf gap of 5, 10 and 20 mm. VMAT plans of AAPM TG-119 phantom and twenty clinical real cases were planned on each machine. Based on AAPM TG-119 guidelines, we compared the machine on their ability to fulfill the dose goals; the pretreatment quality assurance was done with COMPASS QA system (IBA dosimetry, Germany). In order to evaluate how the measured and the planned data from each machine are closed. The monitor units’ numbers for each site and machine were also compared. For simple plans, all the three machines easily meet the goals; however, for complex shape case, only the 5 and 10 mm minimum leaf gap machines allow the user to reach the goals. Otherwise, the 20 mm minimum leaf gap machine presents lower difference between planned and measured dose and the best gamma scores than the two others machines. It also has the lower MUs per clinical site. Based on this investigation, 10 mm is the best compromise value for the dynamic minimum leaf gap into Pinnacle. It allows the planner to reach high complex goals during planning process and in another hand gives good agreement between planned and measured doses.","PeriodicalId":19593,"journal":{"name":"Open Access Library Journal","volume":"6 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89359643","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 proposed algorithm mathematically simulates the behavior of SCA and Arithmetic algorithm behavior in Mathematical. The measure of SCA-AOA has been measured on a set of test functions to know the power of its performance and efficiency, and verify and compare it with SCA and AOA, each one alone. The numerical results have proved that the proposed algorithm (SCA-AOA) is able to present excellent results as compared with SCA-AOA itself. The applied results have proved that the proposed algorithm is able to analyze and break code. It could also avoid the falling the local solution and reaching to the global optimum resolutions in majority of functions that have been applied on. The adoptive Fuzzy SCA-AOA has been proposed and used in analyzing cipher text and breaking the code by merging the proposed algorithm SCA-AOA with properties of fuzzy logic. Moreover, the simple encoding method is explained and used to encode the proposed text. The method of masking by images is explained and used to hide text. The standards are used to measure the image resolution and find the image resolution. The encrypted text was analyzed and returned to the explicit text using the proposed method, SCA-AOA and Fuzzy SCA-AOA both separately, and the code for the encryption was broken by the proposed method.","PeriodicalId":19593,"journal":{"name":"Open Access Library Journal","volume":"2012 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86431874","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}
