This dissertation puts forward RAIM algorithms with the elevation information in the areas as marine navigation. Through this method, the information redundancy can be increased. With only 3 satellites, we can realize positioning calculating. With 5 satellites, we can identify one-faulty satellite. With 6 satellites, we can identify simultaneous two-faulty satellites. According to the simulation analysis, this method can effectively improve the availability of fault detection of RAIM algorithms for one-faulty satellite and two-faulty satellites. In practice, it has profound guiding significance for the improvement of the positioning accuracy and the reliability of the receiver.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"41 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":"116454753","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 detection box slides on the images from the videos from left to right and then from up to down. Since the volunteers wear the green clothes, only the patches of enough green pixels are passed for further processing. Then, three kinds of features i.e. RGB color features, SURF features and HOG features are extracted from the patches. These features are sent to a trained cascade boosting classifier to determine whether the patches are the volunteers. In the experiments, the proposed method demonstrates good performances on three videos.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"21 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":"131569484","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}

Then, some appropriate vocabularies can be selected from the vocabulary set to annotate the 3D models by the similarity between the 3D model to be annotated and the vocabularies in the vocabulary set. In the experiments, three relative parameters are optimized to improve the performance and efficiency. Proved by the experiments, this method proposed in this paper can solve the semantic gap problem.

At the same time, the security of network coding is of importance as the research of network coding increase. Different from previous wiretapping scenarios where the threat is posed by external wiretappers. We discuss the security in an internal angle: all intermediate nodes comply with the communication protocols which are potential wiretappers and the wiretappers can cooperate with each other to decode the packets sent from the source node. Most existing research on network coding designs with a given topology, we will consider the secure network topology design. In this paper, our purpose is to find the secure transmission topology that is suitable for network coding in transmission system. Based on the secure topology, we use network coding scheme which is weakly secure. Mathematical analysis and computer simulations show that the proposed protocol can prevents cooperative eavesdroppers from acquiring any useful information transmitted from source node to sink node.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"28 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":"117200791","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}

To enhance the adaptability of ZMP based walking control, the expected ZMP can be separated as off-line reference ZMP and variable ZMP, and the preview controller and its inverse system can be used to control the trajectory of the center of mass (CoM). But the single predictive control system have a big tracking error for variable ZMP such as rectangular perturbation, the human-simulated predictive control system overcome these shortcomings because of its strong ability to suppress error.
