Firstly, the variable velocity C(I) is used to replace the constant velocity c of the traditional GAC model, and base on the improved GAC model with C(I) to segment the first frame image of the CTPA sequence to obtain a convergent pulmonary artery contour. Secondly, the grayscale information of the target area is used to improve C(I) to V(I), which makes its direction variable. Finally, based on the improved GAC model with V(I), automatic segmentation of pulmonary artery in subsequent images is realized. Among them, the initial contour of each subsequent image is the final contour of the previous image. These two improvement strategies can solve the problem that the model is easy to be over-segmented and drive the curve evolve adaptively inward or outward to the target contour. Experimental results show that the proposed algorithm can realize automatic segmentation of pulmonary artery, and has a high coincidence rate with the results of physician segmentation.","PeriodicalId":231425,"journal":{"name":"2019 IEEE 2nd International Conference on Computer and Communication Engineering Technology (CCET)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127517203","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}

Network emulation method combines the merits of simulation and test-bed, and balances cost and accuracy. This paper introduces a promising cloud-based network emulati on platform, which leverages a set of novel virtualization and cloud related technologies to implement flexibility, agility and scalability in network emulation domain. Aiming at realizing high fidelity (HiFi) network emulation, External physical network nodes should be able to connect and communicate with the emulated nodes. This paper elaborates an innovative strategy to integrate outside physical nodes with virtual nodes inside of the emulation platform to implement virtual and physical nodes fused network emulation. Functional tests are carried out and indicate that the proposed strategy can effectively bridge the physical node to the virtual platform to achieve HiFi network emulation. Besides, performance evaluation also illustrates that the derived strategy can efficiently utilize the limited computation and networking resources of the platform so to achieve sufficient scalability and flexibility for the typical emulation scenarios.","PeriodicalId":231425,"journal":{"name":"2019 IEEE 2nd International Conference on Computer and Communication Engineering Technology (CCET)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116892537","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 current instrumentation optimization technique mainly relies on the control flow graph (CFG) to select key basic blocks at the basic block level, but the accuracy of this method is not high enough. Considering that the actual path in the actual operation of the binary may be different from the CFG generated in advance, this paper is based on the indirect jump that cannot be accurately analyzed in the CFG, and some of the basic blocks that can be optimized for high-frequency interpolation. According to the algorithm proposed in this paper, The combination of static analysis and dynamic analysis is used to continuously adjust and select key basic block nodes for instrumentation. It is verified by experiments that this kind of instrumentation method can effectively improve the coverage rate and reduce the overhead, and provide effective guidance for Fuzzing, which can effectively reduce the Fuzzer’s false negatives.","PeriodicalId":231425,"journal":{"name":"2019 IEEE 2nd International Conference on Computer and Communication Engineering Technology (CCET)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129292933","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}

By analyzing these log messages with vital information such as exception reports, developers can manage and monitor software systems efficiently. Each log message in the log file consists of a fixed part (template) and a variable part, and the fixed parts of log messages with one event type are the same, while the variable part are different. LKE (Log Key Extraction), a widely used log parser for analyzing log messages, can find the fixed parts efficiently, due to the cluster strategy base on the calculation of weighted edit distance between log messages. However, it is time-consuming to calculate the weighted edit distance for large scale log files. In this paper, we proposed a parallel approach using a unique hierarchical index structure to calculate the weighted edit distance on GPU (Graph Processing Unit). GPU has an advantage of high parallelism and is suitable for intensive computing, therefore, the time required to process large-scale logs could be reduced by this approach. Experiments show that LKE parser using GPU to calculate the weighted edit distance has high efficiency and accuracy in the HDFS data set and the marine information data set.","PeriodicalId":231425,"journal":{"name":"2019 IEEE 2nd International Conference on Computer and Communication Engineering Technology (CCET)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121607556","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}
