Among of them, the mining of data association relations and the construction and evolution of relational models are the research hotspots in recent years. How to obtain entities and their relationships from massive data, and then use the relational model to construct the relational graph and support the evolution of the graph is the key problem to be solved. Aiming at the above problems, this paper proposes a method for constructing and evolving relational graphs based on structured data, including source data preprocessing, entity and attribute identification, information extraction, relationship matching, and relational graph construction and evolution. The evolution and update algorithm of the graph based on Simhash and Hamming distance is proposed, and the update strategy of the entity similarity in the graph is analyzed. Combined with experimental verification, this method can automatically realize the extraction of structured data, the construction of relational graph and the evolution and update process of the graph, and the accuracy of the results was about 97%.","PeriodicalId":6739,"journal":{"name":"2019 IEEE 5th International Conference on Computer and Communications (ICCC)","volume":"1 1","pages":"1921-1926"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74599350","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 recent years, chaotic systems have become increasingly important in steganography. This paper proposes an embedding technique based on cyclic chaos, which effectively embeds secret messages into color images. The cyclic chaos is divided into two parts: the chaotic function of generating seeds and the pseudo random number generator (PRNG). A pixel is found through the chaotic cycle system, and a three-bit secret message is embedded into the R, G, and B channels of the pixel through a specific embedding algorithm. Compared with other color image embedding methods, the proposed algorithm has higher visual quality and improved security.","PeriodicalId":6739,"journal":{"name":"2019 IEEE 5th International Conference on Computer and Communications (ICCC)","volume":"23 1","pages":"1798-1802"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74609629","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}

We define the range-DOA information in the phased-array radar as the mutual information between range, direction of arrival (DOA) and the received signal. The theoretical expression and an asymptotic upper bound for this information are presented in a single target scenario. It is concluded that the range information is independent of DOA information at high signal-to-noise ratio (SNR). The relationship between the upper bound and the Cramer-Rao bound (CRB) is discussed. In addition, the scattering information is defined as the mutual information between scattering properties and the received signal. The corresponding expression is formulated theoretically. Numerical simulation confirms our theoretical observations and indicates that the derived information can be employed as an evaluation index to quantitatively analyse the system performance. The regularity of information change reflects the information acquisition efficiency of a radar system, providing a guidance for system designers.","PeriodicalId":6739,"journal":{"name":"2019 IEEE 5th International Conference on Computer and Communications (ICCC)","volume":"183 1","pages":"747-752"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74650662","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}

When multiple air interface technologies coexist, mutual interference will inevitably occur between different working frequency bands (for the same device, we call this interference “self-interference (SI)”). In this paper, for the typical SI of harmonic interference, we propose a new digital-domain interference cancellation method, which can be widely applied to 5G mobile communication systems. By making Band3 (B3) and New Radio78 (n78) work simultaneously, the proposed new method can eliminate the 2nd harmonic generated by the power amplifier (PA) in n78's receiving link. Furthermore, in order to improve the accuracy of nonlinear harmonic components in wideband systems, an equivalent frequency-domain analysis model of harmonic signals is established, following which an iterative channel estimation technique can be employed for improving the accuracy of the proposed scheme. Numerical results demonstrate that the proposed scheme is capable of achieving a high-precision harmonic SI cancellation.","PeriodicalId":6739,"journal":{"name":"2019 IEEE 5th International Conference on Computer and Communications (ICCC)","volume":"73 1","pages":"1011-1015"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75464080","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}

At present, many scholars have conducted in-depth research on various sub-systems of aircraft, and have produced many research results in different aspects. These algorithms have different usage scenarios and application objects. For this problem, this paper proposes an algorithm component model, which was based on network service. This component model encapsulates various algorithms into service components, so that users can call appropriate health algorithms or combine them according to their own needs. Based on this model, the health management system prototype was developed using J2EE platform for functional verification.

This technology can significantly reduce the requirement of the high computational capacity of the VR terminal and is conducive to the promotion of virtual reality services. Accurately measuring user’s perceptual quality of cloud VR services is urgently demanded by VR service providers and network operators to further improve their quality of service. So far, there is still a lack of research about user’s perceptual quality of cloud VR services. In this paper, we conducted a subjective experiment to investigate the impact of frame rate on the perceptual quality of the artificial scene and captured real scene in cloud VR services. Experimental results reveal that different frame rates have different influence on users’ perceptual quality. Moreover, it is found that users’ perceptual quality for the artificial scene and the captured real scene do not have significant difference.","PeriodicalId":6739,"journal":{"name":"2019 IEEE 5th International Conference on Computer and Communications (ICCC)","volume":"153 1","pages":"1226-1230"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78200930","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}
