Although the perception of face has been shown to be mediated by the right hemisphere, whether the discrimination of eye gaze is also mediated by the right hemisphere remains uncertain. In the present study, we attempt to investigate whether the discrimination of human gaze direction is different between the left and right hemispheres. Participants performed a discrimination task using face images in which the face image with gaze was briefly displayed either in the left or right visual hemifield. We found that the discrimination performance of direct gaze was superior to that of averted gaze in the right hemifield when the face image without gaze (control stimulus) was presented in the opposite hemifield. However, the discrimination performance of direct and averted gaze was comparable in the left hemifield. Our findings may reflect a humans' implicit expectation that gaze is directed toward them when the perception of gaze is difficult, which stems from relative difficulty in processing gaze in the non-dominant left hemisphere.","PeriodicalId":427079,"journal":{"name":"2014 6th International Conference on Knowledge and Smart Technology (KST)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124527687","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 other word, missing values are occurred when the customers rate to a few products or services, which bring about to less accuracy of the recommendation. Although the centroid of cluster and SVD are able to solve Sparsity problem, their drawbacks are 1) imputed mean is not derived from user preference and 2) imputed mean does not reflect to the real distribution since imputed mean comes from the average. Therefore, we propose “SVDUPMedianCF” in order to solve the defect of the traditional approach which is an imputation missing value by filling the missing values for each customer with the cluster centroid, obtained from K-means algorithm, of such customer along with singular value decomposition (SVD) in collaborative filtering. According to the experimental evaluation based on MovieLens dataset by using 5-fold cross validation, it has found that imputing missing values with the proposed model presents the lowest mean absolute error when comparison with traditional approach significantly. From the experimental result, the proposed model can improve the quality of recommendation results with significant difference (p<;0.05).","PeriodicalId":427079,"journal":{"name":"2014 6th International Conference on Knowledge and Smart Technology (KST)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123411828","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}

A conventional wiper blade system is suitable for some windshield glass conditions because of its influenced not only by the quality of the wiper blade system, but also by the shape of the windshield glass size. The proposed of SBSA has taken an advantage of single link wiper arm to gain the geometrical criteria which a larger wipe area while still maintain wiper period and can be reduce the complexity of multilink arms mechanism as in the previous design concept. The multi-criteria objectives are not only considered for wipe quality but also constraints by windshield glass feasibility and respect of wiper blade standards. When the direct derivation of the objective functions is not available appeared and some mathematical models that are applied to control the speed regulation of a wiper motor are not precise for more complexes and have some vague systems, so the F-PID controllers can be used to solve this kind of problems that the main advantage of fuzzy logic is that no mathematical modeling is required but can be achieved higher performance with effective tuning methods of the initial setting parameters. By applying the proposed system, performance has been improved by mathematical analysis and simulation programs which indicated by a larger wipe area and reach to the optimum interval wipe period time for more precise of wiper blade's positions in the steady state response and can be reduced the transient state errors that come from any instantaneous disturbances such as instant winding or raining effect and finally for the vehicle drive safety.","PeriodicalId":427079,"journal":{"name":"2014 6th International Conference on Knowledge and Smart Technology (KST)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121918518","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}
