In this paper, an image restoration method in video sequences based on cross-correlation is proposed. A submerged object with modulated light and interference is recorded by a high speed camera. The captured data and the modulated light are regarded as input signal and reference signal, respectively. A new pixel matrix is obtained and can be restored by filtering additive noise after executing a cross-correlation operation between the signals. Experimental results demonstrate that the method can eliminate interference and enhance image quality efficiently.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129750587","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 environment, the research and development of big data platform came into being. Compared to Hadoop MapReduce programming model, the Spark computing framework has a better applicability by introducing RDD (Elastic Distributed Data Set) and memory-based computing model. SparkSQL is an api that integrates relational processing and Sparks functional programming. It provides a better choice for handing massive structured data. However, for the most complex and costly inter-table correlation queries in traditional query, Spark SQL's performance is poor. To some extent, it has affected the application of Spark. This paper first introduces the technical background of Spark architecture, Optimizer Catalyst, and then expounds the factors causing low query performance. Then, a design scheme of cost optimization and predicate pushdown is proposed based on Spark SQL. The proposed scheme is based on scalable Catalyst, which improves the performance degradation due to improper selection of table association algorithm and the triggering of shuffle. Finally, the Spark cluster test environment is built to verify the feasibility and performance improvement of the proposed scheme.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128506001","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}

For this reason, we propose a method based on the traditional FP-Growth algorithm and Word2Vec model to extract product features from online Chinese reviews in the clothing field. This paper has two contributions. One is to add semantic similarity calculation to avoid low-frequency feature words being deleted in the first step of FP-Growth algorithm. The other is to construct semantic rules to extract latent product features, which makes up the deficiency of the traditional association rule algorithm. An experiment is run for the data set of Chinese reviews on clothing products, which shows that the proposed method can improve the accuracy rate without affecting the recall rate.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128526122","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}

But as carrier, the cosine signal has the shortcomings of non-time-varying the signal, fixed frequency, anti-interference and poor security performance. Aiming at these problems, this paper presents a novel modulation and demodulation method, which achieves the fast incoherent demodulation with the linear frequency modulation (LFM) signal as carrier and Fractional Fourier Transform (FRFT). With LFM signal as carrier, that FRFT can be used to achieve rapid demodulation, has been shown in Theoretical analysis and simulation results. In addition, the LFM signal has good performance of anti-interference and confidentiality, compared with the traditional cosine signal as carrier, because it is a time-varying signal, whose time domain and the frequency domain are both changing.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125654351","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 order to reduce the mutual coupling between different resonators and have the compact size, the distance between two adjacent ‘I-shaped’ slots is designed to be 1mm, and the width of ‘I-shaped’ slot is 0.5mm.

Firstly, document was represented as a vector in the space of other language by co-occurrence projection. And then, taking advantage of the latent semantic analysis, the loss of vector caused by polysemy between different languages was remedied. Finally, the cross-lingual cosine similarity of documents was calculated in the same language space possessing equivalent semantic information. External dictionary and knowledge base were sidestepped by using the translation corpus to establish the lexical correspondence among Chinese, English, and Korean. The results show that co-occurrence projection has a great effect in calculating cross-lingual documents similarity, moreover, the retrieval accuracy of translation can be reached 95%, which verifies the effectiveness of the proposed method.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116558697","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, we design a novel hybrid cloud particle swarm optimization (HCPSO) algorithm with genetic algorithm (GA) that is adopted to provide optimal solutions according to the pareto optimality principle in solving multi-objective FJSS problem. It is aimed at minimizing completion time of jobs, total workload and maximum workload. The novelty of the new proposed approach is that the whole particles are divided into three different populations respectively with different weights according to the fitness value. The weight has stable tendency and randomness properties based on the cloud model, which not only improves the convergence speed, but also maintains the diversity of the population. The simulation results show that the HCPSO algorithm has the advantages of small optimization, fast convergence, high efficiency and good population diversity, which verifies the effectiveness and the feasibility of HCPSO algorithm. The results of the instance verify that HCPSO algorithm is suitable for multi-objective optimization problems.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133289036","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 proposed quartic generalized Ball surfaces not only inherit the outstanding properties of the Ball Surfaces, but also have a good performance on adjusting their shapes by changing shape control parameters. To tackle the problem that the engineering complex surfaces can not be constructed by using a single surface, the continuity conditions of quartic generalized Ball surfaces with shape parameter are investigated. Based on the analysis of the basis functions, the conditions of G1 continuity between two adjacent quartic generalized Ball surfaces are proposed. In addition, some applications in quartic generalized Ball surfaces design are discussed.
