An experiment originated from a real world engineering design problem is used to illustrate the accumulation process of novice engineers' empirical knowledge. Two questionnaires are used to test the influencing factors. Through statistics analysis and path analysis, the effects and relations of influencing factors in empirical knowledge accumulation of novice engineers are found. These results will help to capture and accumulate empirical knowledge faster for novice engineers.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125591790","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}

There is a group leader (GL) who manages the group members and group key in each group. In previous studies, selection of GL is seldom discussed, and a new GL is selected according to random numbers in most situations. In this paper, we propose a selecting model based on a trust rating-assessment mechanism to detail the problem of searching GL. Moreover, there are three layers regarding this model, which are record layer, experience layer and distance layer. Through filtering layer by layer, we confirm the only GL in the last layer. In our mechanism, vehicles provide their locations as regions instead of exact points to a location service provider (LSP) to protect their location privacy.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129729942","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 present a novel algorithm for fuzzy segmentation of infrared imaging data. The algorithm is realized by modifying the objective function in the fuzzy C-means with improved fuzzy partition(FCM-IFP) using a kernel-induced distance metric, namely, the original Euclidean distance in the FCM-IFP is replaced by a kernel-induced distance, and thus the corresponding algorithm is derived and called as the kernelized FCM-IFP (KFCM-IFP). This processing method not only can suppress the noise and the outliers, but also can prevent the over segmentation of infrared image even if the contrast between targets and background is insufficient. The experimental results show that the infrared image can be segmented well by the proposed method compared with the conventional clustering method, and the noise, outliers and insufficient contrast are prevented to influence the segmentation of targets region.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131370711","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}
