In this paper, the clearness judgment and blur type identification of tongue images are carried out in order to obtain the accurate blur reasons for further image restoration. For this purpose, this paper first uses the convolution operator (Laplace, Sobel) to obtain the average variance of the tongue image after convolution. Although this method can judge the clearness of the image and severity of blurred images well according to the threshold obtained by using \"threshold optimization algorithm\", it cannot distinguish different types of blurred tongue images. Therefore, based on the deep learning method, this paper further classifies the clear, defocus, Gaussian and motion blurred tongue images. Firstly, we compressed neural networks from the two dimensions of model depth and width. Compared with the original model, the compressed model with a width factor of 16 and a resolution factor of 4 has 0.09% of the parameters of the original model, 0.62% of the calculation amount(FLOPS) and 83.33% of the test time. Secondly, in order to improve the accuracy and robustness of the model, this paper introduces ensemble learning into blur type identification. The model classification accuracy and the average recall are 96.39%, and the average precision is 96.52%, all of which have different magnitudes of improvement.","PeriodicalId":121713,"journal":{"name":"2022 7th International Conference on Computer and Communication Systems (ICCCS)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128533469","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}

Log-based data capture mechanism to capture the addition, deletion, and modification of relational databases in real time, and synchronize the changes of specified fields in the relational database to the non-relational database Elasticsearch in near real time. Elasticsearch stores all search conditions. Using Elasticsearch's advantages in the field of massive data retrieval, it effectively solves the retrieval problem of data tables with excessive data in a single table. At the same time, through the change data capture mechanism, unnecessary indexes in relational databases are reduced, and database data writing is improved. Performance. Applying the retrieval strategy proposed in this article to an industrial Internet situational awareness system proves that the strategy can effectively improve the data retrieval ability and performs well.","PeriodicalId":121713,"journal":{"name":"2022 7th International Conference on Computer and Communication Systems (ICCCS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121917242","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}

Blockchain technology plays an indispensable role in realizing the independent digital identity and economic system which are the significant attributes of the metaverse. To achieve the cross-universe mechanism and reduce network resource consumption, this paper proposes a cross-chain protocol for the underlying architecture of metaverse that utilizes an identity information chain to guarantee the separate digital identity of users and decrease the data interaction between varied consortium blockchains. However, along with the rapid development of quantum computing, the classical cryptosystems which commonly count on mathematical complexity will not be reliable and secure. The current post-quantum cryptography technologies that increase the time complexity of algorithm will lead to quite low efficiency and high resource overhead while applying to blockchain structures. But quantum cryptography is capable of lifting both security and efficiency of blockchain. As a result, the scheme put forward in the article adopts quantum teleportation to implement secure communication. In addition, to assure the atomicity of cross-chain transactions that cross-chain asset exchanges succeed or fail simultaneously, a quantum time lock that improves the previous studies and combines quantum cryptography technology is proposed.","PeriodicalId":121713,"journal":{"name":"2022 7th International Conference on Computer and Communication Systems (ICCCS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125243477","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}

Due to its advantages of wide coverage, multiple connections, low cost, and low power consumption, it has been widely used worldwide. With the advent of the era of 5G Internet of Everything and the growth of China's domestic sharing economy, the market's demand for NB-IoT capacity has increased, and individual scenarios require NB-IoT capacity expansion. In December 2021, China Telecom has written the technical requirements for NB-IoT equipment to support the B3 frequency band into the corporate standard. Under the background of co-construction and sharing between the two major domestic operators, how to use B3(1800MHz) and B5(800MHz) bands for NB-IOT capacity expansion has become a problem to be solved. Considering that the business of the two major operators on the B3 band will evolve to 5G under the background of co-construction and sharing, this paper analyses the characteristics of NB-IoT technology and networking scheme, and proposes the expansion scheme of NB-IoT technology in the B3 and B5 bands in combination with the characteristics of NB-IoT, which provides a reference for operators to jointly use B3 and B5 bands deploy NB-IoT in the future.","PeriodicalId":121713,"journal":{"name":"2022 7th International Conference on Computer and Communication Systems (ICCCS)","volume":"449 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126166748","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}

However, the hardware collectives are not flawless in practical use scenarios. One of the problems is that it is difficult to use. In order to obtain the performance advantage of hardware collectives, the network management software need to create dedicated aggregate tree for each MPI communicator, which is a complicated task. One solution is to make MPI communicators sharing the global imprecise aggregate trees created by the management software when initiating networks, but it leads to heavy interference between MPI communicators and causes significant performance degradation. So we have to make tradeoff between performance and ease of use. We propose a hybrid approach to optimize MPI collectives by in-network-computation and point-to-point messages. On the one hand, we use the pre-created aggregate trees in each super-node, rather than sending requests to the network management software to create dedicated aggregate trees. On the other hand, the hardware collectives are transferred only in the local super-node, so it cannot disturb the jobs running on other super-nodes. We provide a cost model to evaluate the overhead of the hybrid collective algorithms. We also test its performance in the new generation Sunway supercomputer. The results show that our approach reduces the median latency by 18%~74% compared to collectives implemented by point-to-point messages, although the performance decrease slightly compared to the original hardware collectives. In addition, the tail latency of our approach is significantly lower than that of the original hardware collectives in the presence of heavy interference.","PeriodicalId":121713,"journal":{"name":"2022 7th International Conference on Computer and Communication Systems (ICCCS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127588070","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 view of the huge amount of users and data in the cloud computing environment of smart grid, how to design an efficient task scheduling algorithm is a key issue in this field. This paper proposes a task scheduling algorithm based on time and cost. The algorithm realizes the reasonable assignment of tasks through dynamic evaluation of virtual machine nodes. The evaluation factors include execution time, transmission delay and system cost. The first two factors are estimated by performing standard tasks, and the system cost is measured by transmission cost, request processing cost and virtual machine maintenance cost. When the evaluation factors are weighted, the subjective weight and the objective weight are combined to obtain the comprehensive weight, and the users in the power grid are classified at the same time. Users with high ranks give priority to processing efficiency and load balance, while users with low ranks give priority to system cost, thereby providing differentiated services to power users. The results show that, compared with traditional scheduling algorithms such as round robin, the proposed algorithm can effectively improve the load balance and reduce the system cost.","PeriodicalId":121713,"journal":{"name":"2022 7th International Conference on Computer and Communication Systems (ICCCS)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122818241","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}
