The use of a differential file for a database update can yield integrity and performance benefits, but it can also present problems in providing current data to subsequent accessing transactions. A mechanism known as a Bloom

The performance of most small computer systems is determined, to a large extent, by the characteristics of their mass storage devices. Data compression can expand the storage capacity of such devices and also slightly increase …

This paper describes the design and implementation of a
program testing assistant which aids a programmer in the definition, execution, and modification of test cases during incremental program development. The testing assistant …

The volume, moments of inertia, and similar properties of solids are defined by triple (volumetric) integrals over subsets of three-dimensional Euclidean space. The automatic computation of such integral properties for geometrically …

This paper discusses a family of algorithms for computing the volume, moments of inertia, and other integral properties of geometrically complex solids, e.g. typical mechanical parts. The algorithms produce approximate decompositions …

A protection model is presented for a general purpose computing system based on tags attached as
seals and
signatures to values exchanged among processes. A tag attached to a value as a seal does not prevent that value from being …

We study parallel algorithms for a number of graph problems, using the Single Instruction Stream-Multiple Data Stream model. We assume that the processors have access to a common memory and that no memory or data alignment time …
