Wideband Loaded Wire Bow-tie Antenna for Near Field Imaging Using Genetic Algorithms (2008)
Presentation / Conference Contribution
Chung, S., Abd-Alhameed, R. A., See, C. H., & Excell, P. S. (2008). Wideband Loaded Wire Bow-tie Antenna for Near Field Imaging Using Genetic Algorithms. In Progress in Electromagnetics Research Symposium 2008 (PIERS 2008 Cambridge) (308-312)

The potentially broad application area in engineering design using Genetic Algorithm (GA) has been widely adopted by many researchers due to its high consistency and accuracy. Presented here is the initial design of a wideband non-dispersive wire bow... Read More about Wideband Loaded Wire Bow-tie Antenna for Near Field Imaging Using Genetic Algorithms.

Promoting the science and engineering of timber to children. (2008)
Journal Article
Ridley-Ellis, D. (2008). Promoting the science and engineering of timber to children. Timber Engineering,

The UK’s young people are generally very poorly informed about the opportunities that exist for them in wood science and timber engineering, and commonly perceive the sector to be old-fashioned, unrewarding, environmentally damaging, and requiring of...

3D lattice model for post-yield and fracture behaviour of timber. (2008)
Journal Article
Reichert, T., & Ridley-Ellis, D. (2008). 3D lattice model for post-yield and fracture behaviour of timber. Timber Engineering,

The paper describes the development of a bespoke Finite Element program to model timber with a three dimensional lattice of single spring elements. These springs mimic meso-scale timber behaviour, namely the crushing and separation of fibre bunches b... Read More about 3D lattice model for post-yield and fracture behaviour of timber..

Quotidian bus journeys: City life reflections on Lothian buses (2008)
Thesis
Noble, A. F. Quotidian bus journeys: City life reflections on Lothian buses. (Thesis). Napier University. Retrieved from http://researchrepository.napier.ac.uk/id/eprint/2396

The main objectives of this research are to investigate the interaction between the city of Edinburgh, Lothian Buses (Edinburgh’s principal public transport provider) and people using specific bus routes within the city boundaries. A single overarchi... Read More about Quotidian bus journeys: City life reflections on Lothian buses.

Properties of UK-Grown Sitka Spruce: Extent and Sources of Variation. (2008)
Journal Article
Moore, J., Lyon, A. J., Ridley-Ellis, D., & Gardiner, B. A. (2008). Properties of UK-Grown Sitka Spruce: Extent and Sources of Variation. Timber Engineering,

Structural timber produced from Sitka spruce plantations in the UK typically achieves the requirements for the C16 strength class. However, very little is known about the variability of this plantation resource, or the factors that contribute to this...

Resistively Loaded Wire Bow-tie Antenna for Microwave Imaging By Means of Genetic Algorithms (2008)
Presentation / Conference Contribution
Chung, S., Abd-Alhameed, R., Excell, P., See, C., Zhou, D., & Gardiner, J. (2008, June). Resistively Loaded Wire Bow-tie Antenna for Microwave Imaging By Means of Genetic Algorithms. Presented at International Multi-Conference on Engineering and Technological Innovation, Orlando, Florida, USA

The initial design of a wideband non-dispersive wire bow-tie antenna using GA is presented here, primarily for microwave imaging application. The wire bow-tie antenna is designed to operate from 4 GHz to 8 GHz which is essential for microwave penetra...
