A current source inverter with series connected AC capacitors for photovoltaic application with grid fault ride through capability
Presentation / Conference Contribution
Photong, C., Klumpner, C., & Wheeler, P. (in press). A current source inverter with series connected AC capacitors for photovoltaic application with grid fault ride through capability. In 2009 35th Annual Conference of IEEE Industrial Electronics. https://doi.org/10.1109/IECON.2009.5414954

The current source inverter (CSI) is preferred to interface a renewable source such photovoltaics (PV) to the AC power grid because it can provide smooth current source in the DC side, which fits to the PV behaviour and also steps-up the voltage from...

The effect of baroque music on the PassPoints graphical password
Presentation / Conference Contribution
Gao, H., Ren, Z., Chang, X., Liu, X., & Aickelin, U. (in press). The effect of baroque music on the PassPoints graphical password.

Graphical passwords have been demonstrated to be the possible alternatives to traditional alphanumeric passwords. However, they still tend to follow predictable patterns that are easier to attack. The crux of the problem is users’ memory limitations.... Read More about The effect of baroque music on the PassPoints graphical password.

Efficiency evaluation of a novel supercapattery stack with a power electronic interface for energy storage systems
Presentation / Conference Contribution
Kulsangcharoen, P., Klumpner, C., Zhou, X., Peng, C., Chen, G. Z., Rashed, M., & Asher, G. (in press). Efficiency evaluation of a novel supercapattery stack with a power electronic interface for energy storage systems.

The increase of renewable energy generation seen as the only way to ensure clean and sustainable development, is under scrutiny due to its intermittent nature and an insufficient development of com-plementary technologies such as electrical energy st...

Design analysis of a hybrid jet-pump CO2 compression system
Presentation / Conference Contribution
Worall, M., Omer, S., & Riffat, S. (2010). Design analysis of a hybrid jet-pump CO2 compression system.

Transport refrigeration contributes to anthropogenic global warming directly because of leakage of refrigerant, usually using high global warming potential (GWP) refrigerants, and indirectly because of the greenhouse gases emitted in driving the vehi...

Integrity management and the public service ethos in the UK: patchwork quilt or threadbare blanket?
Presentation / Conference Contribution
Heywood, P. M. Integrity management and the public service ethos in the UK: patchwork quilt or threadbare blanket?.

This paper focuses on the nature of integrity management in contemporary UK public life. Despite traditionally high standards of integrity in the public service, it has recently been argued that the UK’s National Integrity System resembles a patchwor...

A comparison of non-stationary, type-2 and dual surface fuzzy control
Presentation / Conference Contribution
Benatar, N., Aickelin, U., & Garibaldi, J. M. (in press). A comparison of non-stationary, type-2 and dual surface fuzzy control.

Type-1 fuzzy logic has frequently been used in control systems. However this method is sometimes shown to be too restrictive and unable to adapt in the presence of uncertainty. In this paper we compare type-1 fuzzy control with several other fuzzy ap... Read More about A comparison of non-stationary, type-2 and dual surface fuzzy control.

"Deutschland kann nur durch Deutschland gerettet werden": der Kampf um das nationale Erbe der Befreiungskriege am Berliner Dönhoffplatz im 19. und 20. Jahrhundert
Book
Haase, C., & Kreuzer, J. "Deutschland kann nur durch Deutschland gerettet werden": der Kampf um das nationale Erbe der Befreiungskriege am Berliner Dönhoffplatz im 19. und 20. Jahrhundert. University of Nottingham. Manuscript submitted for publication

The former Dönhoffplatz has been renamed the Marion-Gräfin-Dönhoff-Platz in 2010. The University of Nottingham provided the historical background research on the history of the Platz which dates back to the 1740s. The findings are presented in this P...

Use of enterprise simulation to assess the impacts of remanufacturing operations
Presentation / Conference Contribution
Farr, R., & Lohse, N. Use of enterprise simulation to assess the impacts of remanufacturing operations.

Remanufacturing could become a cornerstone of a future sustainable society and considerable progress has been made towards finding technical solutions for the renovation of products or selected components. Not all the barriers to remanufacturing are... Read More about Use of enterprise simulation to assess the impacts of remanufacturing operations.

A simulation-based framework for a mapping tool that assesses the energy performance of green roofs
Presentation / Conference Contribution
Kokogiannakis, G., & Darkwa, J. A simulation-based framework for a mapping tool that assesses the energy performance of green roofs.

This paper presents a framework for the development of a GIS open source mapping tool that aims to disseminate a database with results of detailed simulations in order to assess in a quick and easy way the energy performance of green roof designs acr...

Variance in system dynamics and agent based modelling using the SIR model of infectious diseases
Presentation / Conference Contribution
Ahmed, A., Greensmith, J., & Aickelin, U. Variance in system dynamics and agent based modelling using the SIR model of infectious diseases.

Classical deterministic simulations of epidemiological processes, such as those based on System Dynamics, produce a single result based on a fixed set of input parameters with no variance between simulations. Input parameters are subsequently modifie... Read More about Variance in system dynamics and agent based modelling using the SIR model of infectious diseases.

Density-dependent fitness benefits in quorum-sensing bacterial populations
Journal Article
Darch, S. E., West, S. A., Winzer, K., & Diggle, S. P. Density-dependent fitness benefits in quorum-sensing bacterial populations. Proceedings of the National Academy of Sciences, 109(21), https://doi.org/10.1073/pnas.1118131109

It has been argued that bacteria communicate using small diffusible signal molecules to coordinate, among other things, the production of factors that are secreted outside of the cells in a process known as quorum sensing (QS). The underlying assumpt... Read More about Density-dependent fitness benefits in quorum-sensing bacterial populations.

Education and development in Africa: lessons of the past 50 years for beyond 2015
Presentation / Conference Contribution
McGrath, S. Education and development in Africa: lessons of the past 50 years for beyond 2015.

As we move to discuss the nature of development targets post 2015, it is timely to consider what lessons can be learnt from 50 years of experiences of attempts to link education and development in Africa. This paper offers a historical account of key... Read More about Education and development in Africa: lessons of the past 50 years for beyond 2015.
