Quantifying the Evolution of Soil Fabric Under Different Stress Paths (2009)
Presentation / Conference Contribution
Barreto, D., O’Sullivan, C., & Zdravkovic, L. (2009, July). Quantifying the Evolution of Soil Fabric Under Different Stress Paths. Presented at AIP Conference Proceedings

It is well recognized that the macro-scale response of soils is anisotropic in terms of strength, stiffness, permeability, etc. The source of this anisotropy is thought to be an anisotropy of the material itself. This anisotropy can be quantified usi... Read More about Quantifying the Evolution of Soil Fabric Under Different Stress Paths.

Design of Wideband Balanced Folded-Arms Dipole Antenna for Mobile Handsets (2009)
Journal Article
Zhou, D., Abd-Alhameed, R. A., See, C. H., & Excell, P. S. (2009). Design of Wideband Balanced Folded-Arms Dipole Antenna for Mobile Handsets. Electromagnetics, 29(8), 641-651. https://doi.org/10.1080/02726340903287406

Investigations of a wideband balanced antenna for mobile handsets covering three bands—GSM1800, GSM1900, and UMTS—are presented. Balanced antennas have advantages in handset applications as they are less affected by juxtaposition with human tissue th...

Wind resource assessment in the Edinburgh region (2009)
Presentation / Conference Contribution
Irshad, W., Goh, K., & Kubie, J. (2009, September). Wind resource assessment in the Edinburgh region. Presented at 2009 World Non-Grid-Connected Wind Power and Energy Conference, Nanjing, China

In recent years, a growing number of manufacturers have produced small wind turbines that are suitable for utilization of wind energy by individual householders or small businesses. These small wind turbine systems are unavoidably installed close to... Read More about Wind resource assessment in the Edinburgh region.

Quadrifilar Helical Antenna Design for Satellite-Mobile Handsets Using Genetic Algorithms (2009)
Journal Article
