TL;DR: This work introduces the uniquely cloud-based Biodiversity and Climate Change Virtual Laboratory (BCCVL), which provides access to numerous species distribution modelling tools; a large and growing collection of biological, climate, and other environmental datasets; and a variety of experiment types to conduct research into the impact of climate change on biodiversity.
Proceedings ArticleDOI
Optimising efficiency and gain of small meander line RFID antennas using ant colony system
TL;DR: This paper explores the use of a multi-objective version of ant colony system using a constructive meta-heuristic to solve the optimisation problem of RFID antenna design.
Book ChapterDOI
Using Ant Colony Optimisation to Construct Meander-Line RFID Antennas
TL;DR: In this article, an overview of the automatic design of antennas using the meta-heuristic known as Ant Colony Optimization (ACO) is presented, where a novel local search refinement operator and a multi-objective version of the problem are also described.
Proceedings ArticleDOI
Local search for Ant colony system to improve the efficiency of small meander line RFID antennas
TL;DR: This work uses the operator known as backbite, that has had previous application in the construction of self-avoiding walks and compact polymer chains, and applies it in a novel, hierarchical manner that allows for good sampling of the local search space.
Proceedings ArticleDOI
Using XMPP for ad-hoc grid computing - an application example using parallel ant colony optimisation
Gerhard Weis,Andrew Lewis +1 more
TL;DR: The application example described in this paper uses Ant Colony System (ACS) optimisation and the NEC-tool to optimise RFID antennas, involving computing the efficiency and resonant frequency of a large number of different antenna structures.
