However, such services often face challenges when dealing with large numbers of users and high concurrency requests. To overcome these challenges, this article proposes a cluster-based approach that utilizes Nginx as a reverse proxy to ensure high availability and load balancing among nodes, and container technology to dynamically scale and adapt to changing workloads. Additionally, caching techniques are used to speed up large file preview response times, and security features such as anti-replay and anti-leeching are implemented to ensure secure preview control. The effectiveness of this approach is validated through both experimental testing and real-world user experiences.","PeriodicalId":145263,"journal":{"name":"2023 5th International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131217641","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 this paper, a method of fractal image coding based on fixed dictionary instead of changing dictionary is proposed. Different curves are generated by changing the parameters of the Mandelbrot set, and the corresponding image blocks are obtained by quantizing the gray-scale values of the curves, which can form a rich compression dictionary. In the process of encoding, the image block to be encoded is matched with the image block in the dictionary to select the image block that meets the conditions, and then the corresponding image block is encoded, so the fractal coding compression of the image can be realized. The experimental results show that the algorithm is feasible and effective, the image compression effect is ideal, and the speed of fractal coding is greatly improved.","PeriodicalId":145263,"journal":{"name":"2023 5th International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115142957","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}

FL can improve the machine learning performance by updating model parameters via local training. We investigate the joint design of the user scheduling and receiver beamforming vector to minimize the distortion of the aggregated signal. To this end, we formulate a non-convex data aggregation optimization problem taking into account the impact of channel state information (CSI) and user scheduling. To solve this non-convex optimization problem, we decouple the original problem into two subproblems. First, we solve the receiver beamforming design problem for a given user scheduling result. Then, we propose a novel channel and data based user scheduling algorithm to obtain the over-the-air aggregation results. The simulation results show that the proposed scheme is more effective than the benchmark schemes.","PeriodicalId":145263,"journal":{"name":"2023 5th International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128794945","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 proposes a clustering cleaning method based on Stacked Sparse Autoencoders (SSAE) to clean up faulty data. By using SSAE to extract features and reduce dimensionality of the waveform data uploaded by DTU devices, the clustering by fast search and find of density peaks (CFSFDP) algorithm is then used to cluster and clean up erroneous and faulty data. The network parameters are reasonably adjusted to ensure a high correct cleaning rate while maintaining a low erroneous cleaning rate. Comparative analysis proves the superiority of the CFSFDP algorithm in isolating interference, errors, and invalid waveforms. Effective filtering of erroneous and faulty data is achieved through pre-cleaning and complete cleaning, which improves the quality of the database data and provides technical support for subsequent data mining research and effective support for accurate fault diagnosis.","PeriodicalId":145263,"journal":{"name":"2023 5th International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116555472","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}

PBCH DMRS is specifically designed to provide channel information for PBCH demodulation. Because SSS is adjacent to DMRS and has the same EPRE as DMRS, SSS can be used for PBCH channel estimation with DMRS to improve the accuracy of channel estimation. Although PSS is also adjacent to DMRS, it can not be used for PBCH channel estimation due to the unknown EPRE ratio of PSS to DMRS. This paper proposes a scheme to estimate the EPRE ratio of PSS to SSS/DMRS. Simulation results show that the proposed scheme can estimate the EPRE ratio accurately when SNR is above −4dB and joint channel estimation with PSS, SSS and DMRS can improve the success probability of cell search greatly compared to channel estimation with DMRS only.","PeriodicalId":145263,"journal":{"name":"2023 5th International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"76 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130580227","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 number of false stars in the star image taken by the star sensor with wide Field-Of-View will increase, and the position of star will be seriously offset. This paper proposes a neural network star identification algorithm based on equal-frequency binning radial feature (EFB-RF). The EFB-RF is a robust star pattern. A superficial neural network is used to classify EFB-RF. The results show that our algorithm is robust to position noise, false stars, and missing stars. The identification rate of our algorithm can reach 99.92% under 1 pixel position noise, and it can reach 99.37% under 5% false stars. When the percentage of missing stars is 15%, it can reach 99.97%. The results show this algorithm is robust to position noise, false star and missing star in a wide-FOV, and it can help star sensor work properly in complex space environment.","PeriodicalId":145263,"journal":{"name":"2023 5th International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128037579","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}

Next, the length of the T shaped stub integrated two varactor diodes can affect the radiation field of the antenna, and further affect the ARBW of the proposed antenna. Therefore, the coverage area of the CP signal is adjusted flexibly.
