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}

For such system, the major problem is how to achieve high accuracy. Our solution is based on the high performance counter, which is an ordinary part of most computers in recent years. The time stamp is recorded in every single PC when any event happens instead of sending a command at the same time which is the ordinary method. Before grabbing signals, the start points of time stamp are calibrated by sending a short code circularly in order to find the timestamp corresponding to the shortest duration. Experiments show that the oscillator frequency got by system API is not reliable, so the coefficient has to be calibrated for every PC, and the result show that least square method can achieve satisfied accuracy. The system has potential values in real application, such as affective computing or micro expression recognition.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"5 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":"125574543","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}

It is essential to recognize information units like the phrases and digital numbers. Identifying references to these entities in text was recognized as one of the important sub-tasks of IE and was called \"NER and Classification \". In this paper, we propose a (NER) technique, which uses text classification methods for annotating the phrases and digital numbers to develop the query to be searched in the index. We also investigate which exploits the duality between set of the phrases and digital numbers to grow the target relation, assign the high scores, a passage extraction and ranking component. The overall architecture applied during development is described. To test our technique we use it to extract a relation of the phrases and digits pairs from the Web.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"259 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":"114531463","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 selection of main engine and the water-jet propulsion pump was made. A mathematical model of the system was established on these bases. The PID controller of diesel engine speed and the speed fuzzy controller of water-jet propulsion system were designed. The overall system model was obtained on the MATLAB/SIMULINK platform.

This paper proposes a model to combine road traffic state with bus travel to form the Bayesian network, with a lot of historical data, the parameter of network can be achieved, through estimating the real-time traffic status, so as to predict the bus travel time. We introduced Markov transfer matrix to forecast the traffic state, and substitute the estimate state value into the joint distribution of bus travel time and state, the real time bus travel time predicted value can be obtained. Bus travel time predicted by the proposed model is assessed with data of transit route 69 in Guangzhou between two bus stops, the results show that the proposed model is feasible, but the accuracy needs to be further improved.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"32 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":"123054481","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}
