: Spatial data types or algebras for database systems should (i) be fully general (which means, closed under set operations, hence e.g. a region value can be a set of polygons with...
Abstract—This paper studies the foundations of informationflow security for interactive programs. Previous research assumes that the environment is total, that is, it must alway...
In previous papers, a passive control implementation structure is proposed for mechanical systems interacting with physical environments. The proposed implementation structure enf...
Abstract. The database server is a crucial bottleneck in traditional inference control architecture, as it enforces highly computation-intensive auditing for all users who query th...
Software systems are becoming heterogeneous: instead of a small number of large programs from well-established sources, a user's desktop may now consist of many smaller compo...
