Consistency maintenance for constraint in role-based access control model     

韩伟力  陈刚  尹建伟  董金祥 《浙江大学学报(A卷英文版)》2002,3(3):292-297

Constraint is an important aspect of role-based access control and is sometimes argued to be the principal motivation for role-based access control (RBAC). But so far few authors have discussed consistency maintenance for constraint in RBAC model. Based on researches of constraints among roles and types of inconsistency among constraints, this paper introduces corresponding formal rules, rule-based reasoning and corresponding methods to detect, avoid and resolve these inconsistencies. Finally, the paper introduces briefly the application of consistency maintenance in ZD-PDM, an enterprise-oriented product data management (PDM) system.  相似文献   

Jacquard image segmentation using Mumford-Shah model     

冯志林  尹建伟  陈刚  董金祥 《浙江大学学报(A卷英文版)》2006,7(2):109-116

INTRODUCTION Image segmentation plays an essential role in jacquard image analysis. A jacquard image consists of many complex patterns which contain detailed, in- tricate topological curves. An accurate extraction of pattern features from jacquard images promises reli- ability for jacquard fabric CAD. Although, many algorithms have been proposed for the segmentation problem, they have difficulty in capturing the com- plex structure of the visual features, such as complex contours of a ja…  相似文献
