We present a typed polymorphic calculus that supports a general mechanism for view definition and object sharing among classes. In this calculus, a class can contain inclusion spe...
We show how to combine a general purpose type system for an existing language with support for programming with binders and contexts by refining the type system of ML with a rest...
We propose two algorithms for grouping and summarizing association rules. The first algorithm recursively groups rules according to the structure of the rules and generates a tre...
We present a strategy to derive an efficient reference count garbage collector for any applicative program by only modifying it on the source code level. The key to the approach is...
In this paper we investigate P systems whose compartments contain sets of symbolobjects rather than multisets of objects, as it is common in membrane computing. If the number of m...
