The PolicyUpdater1 system is a fully-implemented access control system that provides policy evaluations as well as dynamic policy updates. These functions are achieved by the use o...
Abstract. Properties of programs can be formulated using various techdataflow analysis, abstract interpretation and type-like inference systems. This paper reconstructs strictness...
The lineage of a piece of data is of utility to a wide range of domains. Several application-specific extensions have been built to facilitate tracking the origin of the output th...
During maintenance, systems are updated to correct faults, improve functionality, and adapt the software to changes in its execution environment. The typical softwareupdate proces...
This paper defines an extended polymorphic type system for an ML-style programming language, and develops a sound and complete type inference algorithm. Different from the conve...
