Increasing Confidence in Mass Discharge Estimates Using Geostatistical Methods (2011)
Journal Article
Cai, Z., Wilson, R. D., Cardiff, M. A., & Kitanidis, P. K. (2011). Increasing Confidence in Mass Discharge Estimates Using Geostatistical Methods. Groundwater, 49(2), 197-208. https://doi.org/10.1111/j.1745-6584.2010.00709.x

Mass discharge is one metric rapidly gaining acceptance for assessing the performance of in situ groundwater remediation systems. Multilevel sampling transects provide the data necessary to make such estimates, often using the Thiessen Polygon method...

Compact Tunable Microstrip F-Slot antenna for Mobile Handset Applications (2011)
Presentation / Conference Contribution
Elfergani, I., Abd-Alhameed, R. A., See, C. H., Abidin, Z., Hraga, H., & Excell, P. (2011). Compact Tunable Microstrip F-Slot antenna for Mobile Handset Applications.

This paper presents a design for a single-feed, compact, tunable microstrip F- slot antenna capable of achieving high tuning ranges without using any matching networks. An F shaped slot embedded in a patch is used to generate resonant frequencies. Th... Read More about Compact Tunable Microstrip F-Slot antenna for Mobile Handset Applications.

Optimised concentrator for the Solar Photonic Optoelectronic Transformer System: First optimisation stage (2011)
Journal Article
Muhammad Sukki, F., Ramirez-Iniguez, R., McMeekin, S., Stewart, B., & Clive, B. (2011). Optimised concentrator for the Solar Photonic Optoelectronic Transformer System: First optimisation stage. Caledonian Journal of Engineering, 7(1), 19-24

Collecting and storing solar energy will be a key part of efficient renewable technologies for buildings of the future, particularly in the Middle East. This paper presents the topic of improved properties of optical concentrators to achieve increase...

A counter-example to “Positive realness preserving model reduction with H-\infty norm error bounds” (2011)
Journal Article
Guiver, C., & Opmeer, M. R. (2011). A counter-example to “Positive realness preserving model reduction with H-\infty norm error bounds”. IEEE Transactions on Circuits and Systems I: Regular Papers, 58(6), 1410-1411. https://doi.org/10.1109/tcsi.2010.2

We provide a counter example to the H∞ error bound for the difference of a positive real transfer function and its positive real balanced truncation stated in “Positive realness preserving model reduction with H-\infty norm error bounds” IEEE Trans....

Numerical Simulation of Drain Performance in Liquefiable Soils (2011)
Presentation / Conference Contribution
Bouckovalas, G., Dimitriadi, V., Tsiapas, Y., & Tsioulou, A. (2011, January). Numerical Simulation of Drain Performance in Liquefiable Soils. Paper presented at 5th International Conference on Earthquake Geotechnical Engineering, Santiago, Chile

Modern approaches for the design of drains for liquefaction mitigation are based on the work of Seed and Booker (1977) for infinitely permeable drains and uniform soil with purely horizontal drainage. More recently, Bouckovalas et al. (2009) revisite... Read More about Numerical Simulation of Drain Performance in Liquefiable Soils.

Exploring the effects of stress history on the drained and undrained cyclic behaviour of granular materials. (2011)
Presentation / Conference Contribution
Barreto, D. (2011, January). Exploring the effects of stress history on the drained and undrained cyclic behaviour of granular materials. Paper presented at 5th International Conference on Geotechnical Earthquake Engineering (5-ICEGE)

This paper presents the results of 3D DEM simulations of granular materials subject to cyclic loading. While both the drained and undrained conditions are considered, the effects of depositional history and consolidation stress history on the stress-...

Settlement-The Short and the Long of it (2011)
Presentation / Conference Contribution
McDougall, J. (2011). Settlement-The Short and the Long of it. In D. Zekkos (Ed.), Geotechnical Characterization, Field Measurement, and Laboratory Testing of Municipal Solid Waste (76-111). https://doi.org/10.1061/41146%28395%293

Total settlement in municipal solid waste (MSW) landfills can be considerable, from 25% to 50% of original fill thickness (Bjarngard and Edgers, 1990). Some occurs very quickly, i.e. during the filling phase (or short term), but there remains a signi... Read More about Settlement-The Short and the Long of it.

A booking portal for shared transport in rural areas. (2011)
Presentation / Conference Contribution
Cooper, J. A., Duffell, J., & Nelson, J. D. (2011, January). A booking portal for shared transport in rural areas. Paper presented at Universities Transport Studies Group

Although Demand Responsive Transport (DRT) has developed in a number of urban and rural areas, solutions are local with no mechanism to offer services further afield. Furthermore, transport providers, particularly smaller ones, cannot offer their ser... Read More about A booking portal for shared transport in rural areas..
