The method solves the similarity factor of life evaluation parameters (running time, times of starting and stopping) in actual and benchmark running condition by using experience running data. In order to accurately calculate the running life of the object set under the actual running conditions and overcome the shortcomings of the traditional artificial statistics, the calculation method of real time and historical life is presented. Then based on the product of the maintenance factor and service factor of running time and the times of starting and stopping, the concept of the key parameters of the decision of condition-based maintenanceequivalent service factor is put forward; According to the relationship between the equivalent service factor in running time and to predict period, four kinds of decision models of condition-based maintenance are established. The historical data of communication equipment running were perioded to predict when given equivalent service factor.","PeriodicalId":11066,"journal":{"name":"DEStech Transactions on Computer Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74150322","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 use of Q/V band feeder links and Ka band user links is a feasible solution to support the next iteration of High Throughput Satellite. The gateway transmit diversity technique is a way to compensate the rain attenuation of Q/V band feeder links. This paper analyzes a practical combination scheme that combinates N-active (K=2) with N+1 diversity method in detail from the working principle, gateway handover status transfer process, evaluation of system availability and implementation complexity. Compared with the existing N+P scheme, the proposed scheme can provide higher system availability and more stable user experience under the condition of properly increasing the complexity of payload design. Compared with N-active scheme that has been reported, it is much easier to implement in engineering and more cost-effective. As a result, the combination scheme is an optimized solution based on a tradeoff between performance improvement and complexity of the payload.","PeriodicalId":11066,"journal":{"name":"DEStech Transactions on Computer Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75711548","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 amount of data n in cultural heritage images is constantly amplified in the process of historical development and circulation. It has been significant challenges. The research is based on the international standard ontology reference model CIDOC CRM in the field of cultural heritage. It designs Semantic ontologies and specifications from the perspective of describing, correspondence paths and semantic architecture. The aim is to integrate and correlate the information of cultural heritage images with semantic information. And facilitate the integration and exchange of image information for traditional humanities and social science research. 1 Semantic Web and CIDOC CRM Massive digital information resources meet the needs of the public but gradually show the deficiencies in information representation and utilization. Tim Berners-Lee proposed the Semantic Web (Semantic Web) in 2000. As an extension of the current network, the entire Internet has become an information exchange medium, through basic element semantic links. In actual research, even the same image symbol has different semantics in different time. Only the integration of interdisciplinary research information to achieve the semantics that computers can understand and accelerate the sharing of knowledge and information. The ontology is an important technology to achieve semantic information retrieval. It describes the norms of concepts and the relationships between concepts. CIDOC CRM(CIDOC Conceptual Reference Model) is an object-oriented conceptual reference model developed by International Committee for Documentation. CIDOC CRM has become the international standard in the field of cultural heritage research in 2006, and it is the ontology of the domain of cultural heritage. It provides the semantic definitions and clarifications for the standard specification and description architecture of cultural heritage information, as an important information and reference model of the Semantic Web. Since 2006 it is official standard ISO 21127:2006. Current version is 6.26(June 2019, Published Version), including 98 entities, 168 Properties. It aims at providing the semantic definitions and clarifications needed to transform disparate, and localised information sources into a coherent global resource, be it within a larger institution, in intranets or on the Internet. [1] CIDOC CRM is widely recognized and applied internationally. For example, the \"Digital Storage of Folk Music and Dance Culture\" project funded by the Slovenian State in 2007, integrated the conceptual design of the CIDOC CRM model and FRBR model to","PeriodicalId":11066,"journal":{"name":"DEStech Transactions on Computer Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80106237","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}

It was found that: the Covid-19 has caused a significant negative impact on the online customer inflow, and its overall growth rate decreased. The products related to personal care, gifts and business stationery experienced the most significant decline, while daily necessities maintained a relatively stable customer flow, with little or no decline. In contrast, the products related to pandemic-control exhibited substantial growth in both customer flow and page views.
