Duce 1 is a Machine Learning system which suggests high-level domain features to the user (or oracle on the basis of a set of example object descriptions. Six transformation operators are used to successively compress the given examples by generalisation and feature construction. In this paper Duce is illustrated by way of its construction of a simple animal taxon-omy and a hierarchical parity ...

Nodes in ad hoc networks generally transmit data at regular intervals over long periods of time. Recently, ad hoc network nodes have been built that run on little power and have very limited memory. Authentication is a significant challenge in ad hoc networks, even without considering size and power constraints. Expounding on idealized hashing, this paper examines lower bounds for ad hoc broadc...

T he dissemination of warning messages in a reliable and timely fashion is critical for safety in vehicular ad hoc networks. Conventional telematics solutions use a radar-type mechanism that detects an obstacle ahead of a vehicle and then activates the brakes to avoid a crash. But this technology lets vehicles perceive an obstacle only when it's physically in front of them. If vehicles could ta...
