Modern low earth orbit (LEO) satellites that require multi-mission flexibility are highly likely to be repositioned between different operational orbits. While executing this process the satellite may experience high levels of vibration and environmental hazards, exposing the deployed solar panel to dangerous stress levels, fatigue and space debris, hence it is desirable to retract the solar sa...

The configuration management of a sensor network composed of tens or up to thousands of nodes is difficult due to the limit of memory space and energy consumption. This paper presents an approach for dynamic reconfiguration of application modules in sensor networks based on Nano-Qplus. The version information from proposed methods is registered into NVSync (Nano-Qplus Version Synchronization), ...

10 The refractile (R) bodies found in Caedibacter taeniospiralis, a bacterial endosymbiont of Paramecium 11 tetraurelia, are large, polymeric protein structures that can switch between two conformations. At 12 cytoplasmic pH, they resemble coiled ribbons of protein 500nm in diameter. At low pH, they extend to 13 form hollow needles up to 20 microns long. They can be expressed heterologously fro...

This paper is about distributed scheduling where individual agents have potentially conflicting interests. It is motivated by BT’s workforce scheduling problem, where multiple service providers have to serve multiple service buyers. The service providers and buyers all attempt to maximize their own utility. The overall problem is a multi-objective optimization problem; for example, one has to m...

As a solution to maintain, process and enrich knowledge in the multimedia description framework we are constructing, we propose a forward chaining knowledge base and reasoning engine, supporting RDF documents and OWL Lite ontologies, with the ability to perform non-monotonic, retractable inference. Within our framework, the knowledge over the media collection can be collected in several ways. A...
