After reviewing the basic notations of graph transformation with variables, this article presents specification formalisms for workflow delegation policies using graph transformation with variables. In this research, authorization states are represented by graphs and state transition by graph transformation with variables. The proposed formalization provides an intuitive description for the manipulation of graph structures as they occur in workflow delegation and a precise specification of consistency conditions on graphs and graph transformations. We specifies a type graph to represents the type information in the graph transformation for workflow delegation, a set of rule schemes to build the system states and sets of positive and negative constraints to specify wanted and unwanted framework. Using formal properties of graph transformation, it can to detect inconsistencies between a rules and a constraint and lay the foundation for their resolutions. We present an algorithm to automatically check and eliminate conflicts between rules and positive and negative constraints.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125003748","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 order to improve expansibility, reusability and dynamic adaptability of CAPP system, the work mechanism of an intelligent CAPP system based on multi-agent system was investigated, and this paper researched on the architecture and function of the agents in the intelligent CAPP. The reason of conflict generation was analyzed, and conflict resolution mechanism based on knowledge was represented. The conflicts which intelligent CAPP generated were resolved by use of rule-based reasoning and case-based reasoning, the relevant agents were developed, the investigation achievement was applied in the process of producing shearer.

The main principle of the proposed scheme is to introduce the concept of normalized colinearity (NC) into the selection phase of beacon nodes. Based on DV-Hop, best available anchor terns are elected to accomplish more accurate localization by using NC. The experimental results show that the location accuracy of the proposed algorithm outweighs significantly the DV-Hop algorithm, especially in the cases where the connectivity is lower than 10.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125182821","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}

After discussing the longitudinal equation of motion, the relationship between consumption time and other state variables is obtained by disposing the aircraft equations of dynamics and motion. Based on the relationship, the time interval between any adjacent grids in the vertical plane is figured out. Finally, the minimum time cost for climbing from one flight point to the target point is calculated by dynamic programming (DP) method. The numerical simulation shows that, the algorithm presented in this paper which based on adjacent grids and DP can find the optimal flight trajectory series which is realizable in designated flight envelope, and the time cost of obtained trajectory serried satisfies with the requirement.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125217046","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 proposed algorithm is based on wavelet transform and linear least square fitting method. First, a skew feature image of the original track image, which preserves the track's horizontal feature, is extracted by the wavelet transform. Given a threshold, the skew feature image is then transformed a binary image, in which most of the object points correspond to the top or bottom ends of tracks. Those object points are fitted by using linear least square method to get a line for each top or bottom end row of tracks. The average value of the skew angle of the several lines is regarded as the skew angles of the track images. Experimental results show that this algorithm performs well on track images. The effects of various wavelet basis are investigated too.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133555849","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}
