Scalable WIM: Effective Exploration in Large-scale Astrophysical Environments

An Efficient Data Replication Strategy in Large-Scale Data Grid Environments Based on Availability and Popularity

The data grid technology, which uses the scale of the Internet to solve storage limitation for the huge amount of data, has become one of the hot research topics. Recently, data replication strategies have been widely employed in distributed environment to copy frequently accessed data in suitable sites. The primary purposes are shortening distance of file transmission and achieving files from ...

Localisation in large-scale environments

This paper describes a localisation framework that combines the accuracy of feature maps with the scalability of topological maps. The map is structured as a graph of nodes where each node defines a local region feature map. This breaks the localisation process into a combination of regional feature tracking and node-to-node context switching. As part of the practical implementation of the loca...

MAS-based, Scalable Allocation of Resources in Large-scale, Dynamic Environments: (Doctoral Consortium)

I study the resource allocation problem, with a focus on computing environments (Cloud, Internet of Things), by employing market mechanisms such as auctions that consider supply and demand, and dynamic pricing in the decision process. However, current approaches face two limitations: (i) centralisation, as there is typically a central entity (such as an auctioneer) that holds all the informatio...

Project Innovation Through Exploration and Exploitation: Requirements Practice in Large-Scale IS Development Environments

The exploration of new opportunities and the exploitation of existing competencies represent two competing logics for innovation and change within organizations. IS projects seeking to foster innovation need to balance these forces, and recognize the distinct role that each plays. Through its essential role in generating a design space between existing problems and design options, the requireme...
