Information technology is the main driving force for the development of media convergence, and it is also a shortcoming that traditional media urgently needs to make up for. Since 2018, county-level convergence media centers across the country have been under construction, using advanced technologies such as AI, VR, 5G, big data, cloud computing, artificial intelligence, and microservice architecture, to build a technologically leading “provincial convergence media platform” solution. This article takes Province F as an example to illustrate the platform technology architecture of the county-level convergence media center, in order to provide a guarantee for the construction of the content platform.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127007723","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}

Firstly, the fractional Fourier (FRF) domain correlation matrix of array received signal with wideband LFM interference is derived to replace the traditional correlation matrix. Then, the PI algorithm is used to suppress the wideband LFM interference in the FRF domain. Finally, the inverse FRFT is taken to get the signal with the LFM interference being mitigated. Simulation results demonstrate that the proposed method can effectively suppress the wideband LFM interference. Even though the direction-of-arrival(DOA) of the GNSS signal is similar to or even the same as that of the wideband LFM interference, it can also effectively suppress the interference signal without causing significant GNSS signal loss, and it can provide correctly acquisition.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130918076","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}

Finally, the final feature obtained by concatenating multiple global features is used for retrieval.

There are various requirements for temporary log analysis, such as fault location, business characteristics analysis, and system operation. This kind of requirements are temporary, sudden and diverse. In order to meet this kind of requirements quickly, a distributed visual search and analysis engine system is designed, which has high flexibility and low threshold. The flexibility of the system is enhanced by abstracting the general search and analysis engine module, supporting the configurable extension of statistical dimension and providing user-friendly visual interface. At the same time, for unified management of configuration files, abstract matrix extended framework, which can improve the loading automation of configuration file and descriptibility of dependency relationship.

In order to solve the problem that there are not enough frequency channels for too many users. This work starts with the frequency reuse. An integer frequency reuse (IFR) in 19-cell system network and a fractional frequency reuse (FFR) in 19-cell system network and variation of other factors are analyzed to illustrate the different effects of different frequency reuses on network capacity. Through MATLAB simulation network, the system capacity is calculated, different methods are designed, and the influence of different parameters on system performance is verified, such as cell radius and signal-to-noise ratio. Different methods are selected according to the model to increase the system capacity and optimize the system.

Aiming at the problem that the dose-effect data of traditional Chinese medicine are of multi-dimensional structure and the problem that standard particle swarm optimization (PSO) method may fall into a radical or still state, in this paper, the authors apply softmax regression to the modeling of the fitting of the dose-effect data of traditional Chinese medicine, and suggest a novel method for the data fitting based on a hybrid particle swarm optimization algorithm with taboos and a heuristic strategy. In this study, Min-Max normalization method is used to normalize independent variables and dependent variables. Then the authors conduct a fast dimensional transformation by multiplying a transformation matrix on the right side of independent variable matrix. After that, a mathematic model for the fitting of dose-effect data is built in accordance with softmax regression including a regression formula and an evaluation function. In the end, the authors apply a novel hybrid PSO algorithm with taboos and a heuristic strategy to the fitting of the dose-effect data of traditional Chinese medicine. In the comparative experiments, the authors implemented hill climbing algorithm, conventional genetic algorithm, standard PSO algorithm and our method, and utilized these methods to conduct the fitting of the dose-effect data. Experimental results on the problem of dose-effect data fitting demonstrate that the proposed method significantly outperforms the 3 classic methods with respect to accuracy in the conducted experiments. And our method is more efficient than hill climbing algorithm and conventional genetic algorithm in comparative experiments.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134491170","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}

Empirical mode decomposition (EMD) was used to denoise and stabilize the original data, and the intrinsic mode function components represented different frequency scales were obtained. By calculating the sample entropy of each component, the components with similar sample entropy were recombined to avoid error accumulation; After considering the impacts of seasonality and major events on sales, especially the fluctuations caused by COVID-19, an event window of holidays was established and the Prophet model was applied to predict each component. Every result was accumulated to form the final one. Finally, the model was validated by the data of the automobile industry chain platform and compared with ARIMA, Prophet and EMD-ARIMA models. The experimental result shows that the prediction accuracy of EMD-Prophet model is higher than other models, which verifies the effectiveness of the model.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121937323","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}
