Construction of complex array operations by composition of more basic ones allows for abstract and concise specifications of algorithms. Unfortunately, na¨ıve compilation of suc...
The per-method access control lists of standard middleware technologies allow only simple forms of access control to be expressed and enforced. Research systems based on capabilit...
The latest ontology languages can be translated into a description logic (DL), thus providing them with a formal semantics and associated reasoning procedures. We introduce the or...
This paper presents in detail an efficient and provably correct algorithm for database replication over partitionable networks. Our algorithm avoids the need for end-toend acknow...
We test the hypothesis that: (1) Optic flow can be used to detect significant environmental features during locomotion in a biped, even given significant up and down movement and j...
