Numerical results show that the bit error rate (BER) performance of the proposed algorithm outperforms some existing estimators under the impulsive noise environment.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124556443","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}

Through the roaming technology of the global mobility networks, a legitimate subscriber can enjoy the ubiquitous services. Where, the mutual authentication and key agreement between the mobile subscriber and roaming network (VLR/SGSN) is the primary security aspect of many commercial mobile networks. For personal privacy perspective, it is important to develop a mutual authentication and key agreement scheme with several security features including the user anonymity. In this article, we come up with a novel authentication and key agreement scheme, which can assure privacy against eavesdroppers (PAE) with the subscriber anonymity. Simultaneously, here we argue that the proposed scheme can also withstand several other security vulnerabilities like redirection attack, forging-mobile-user attack and location privacy etc. with the less communication cost.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129347223","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}

Analysis and simulation results show that raised cosine pulse with roll-off coefficient of zero can resist power penalty furthest due to time synchronization errors in PNC when adopting pulse shaping without ISI. Also when adopting Gaussian pulse shaping, we can get the best effect with parameter of one on resisting power penalty due to time synchronization errors in PNC.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115924186","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}

As a result, this paper proposes an adaptive fuzzy ontology for student learning assessment and applies it to mathematics area. First, the domain experts construct the adaptive mathematics fuzzy ontology by referring to the guidelines of mathematics learning area in Grades 1-9 curriculum. The natural language processing mechanism tags each term with its speech and then filters the terms with useless speeches from the response data. Based on the genetic learning mechanism, the fuzzy reasoning mechanism then reasons the similarity strength between the kept terms and the constructed ontology. The semantic summary mechanism next summarizes the students' learning performance based on the inferred results. Finally, the diagnosis report mechanism presents the diagnosed reports to make officers, teachers, and students themselves much understand examinees' learning progress. Experimental results indicate that the proposed method can generate the suitable summarized sentences to allow teachers to quickly understand which mathematical topic is the one that students should be improved in the future.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125824744","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 network lifetime considered in this work is based on the outage probability of the secondary cooperative system. Not only the channel condition of each relay, selection of best relay has to satisfy the interference constraint for primary user as well as the residual power of each relay. Here, we proposed four strategies to select the relay for prolonging the lifetime depending on the channel state information (CSI) and residual energy information (REI). From the simulation results, the minimum outage probability strategy (MOP) performs the best among four strategies.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125866893","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}

An image descriptor is directly derived from the Gabor filtered output statistics of a given image. In general, the magnitude of the Gabor filtered output is modeled as the Gaussian distribution. So that the image descriptor is composed from mean, standard deviation, and skewness value of the Gabor filter magnitude [5, 6, 8]. However, Arrospide et. al. [9] argued that the skewness parameter is not meaningful for the class separation. Then, the feature descriptor is well defined only using mean and standard deviation of Gabor output distribution which leads to lower feature dimensionality. Based on our observation, the magnitude of the Gabor filter has strong tendency to follow the Gamma distribution. We propose a new texture descriptor derived from the maximum likelihood estimation of the Gamma distribution for effectively vehicle verification task. Experimental result shows that the proposed method is superior to the former approach under several classifier techniques.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129520608","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}

Existing methods tackle this problem by modifying the learning algorithms or resampling the datasets. In this paper, we propose a new method called one-vs-all for class imbalance learning (OVACIL) which neither modifies the SVM learning algorithms nor resamples the datasets. In the OVACIL method, we re-group a given imbalanced dataset into a number of new datasets comprising of all the original samples and train standard SVM classifiers using each of the datasets. The output scores of these classifiers on a testing sample are then compared and a final decision is made without a fixed decision threshold. This comparison is not biased toward any particular class, resulting in high accuracies of both classes. The Gmean and Fmeasure values obtained by OVACIL on 18 real-world imbalanced datasets surpass the previous best values reported by other state-of-the-art CIL methods on most of these datasets.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132848476","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}
