Coalition formation is a process whereby agents recognise that cooperation with others can occur in a mutually beneficial manner and therefore the agents can choose appropriate temporary groups (named coalitions) to form. The benefit of each coalition can be measured by: the goa…

This work contributes to knowledge in the field of semiconductor system architectures, circuit design and implementation, and communications protocols. The work starts by describing the challenges of interfacing legacy analogue subscriber loops to an electronic circuit contained…
This thesis considers the placement of two or more Unmanned Aerial Vehicles (UAVs) to provide communications to a community of ground mobiles. The locations for the UAVs are decided by the outcome of a non-cooperative game in which the UAVs compete to maximize their coverage of …
Limit order book markets are a rich research area, not only because these markets generated huge amounts of data (at an exceedingly high rate), but also because the fine level of detail that their data enables one to explore market microstructure in unprecedented ways. Due to th…
This thesis describes research conducted in the field of image mining especially volumetric image mining. The study investigates volumetric representation techniques based on hierarchical spatial decomposition to classify three-dimensional (3D) images. The aim of this study was …
Thousands of websites providing an array of diversified online services have been the crucial factor for popularising the Internet around the world during last 15 years. The current model of accessing the majority of those services requires users to register with a Service Provi…
Profiling tools are essential for understanding and tuning the performance of both parallel programs and parallel language implementations. Assessing the performance of a program in a language with high-level parallel coordination is often complicated by the layers of abstractio…
Practical computers have only finite amounts of memory. However, the programs that run on them are often written in languages that effectively assume (via providing constructs such as general recursion) that infinite memory is available, meaning that an implementation of those p…
This thesis studies algorithms for Distributed Computing. More specifically however the project aimed to carry out research on the performance analysis of mobile robots in a variety of different settings. In a range of different network and geometric settings we investigate effi…
Finding easier and less resource-intensive ways of building knowledge resources is necessary to help broaden the coverage and use of semantic web technologies. Crowdsourcing presents a means through which knowledge can be efficiently acquired to build semantic resources. Crowds …
Creep deformation and failure in high temperature structures is a serious problem for industry and is becoming even more so under the current increasing pressures of power, economics and sustainability. Laboratory creep tests can be used in the description of creep damage behavi…
This research project examines how video games can be programmed to generate the sense of the digital sublime. The digital sublime is a term proposed by this research to describe experiences where the combination of code and art produces games that appear boundless and autonomou…
Existing home care technology tends to be pre-programmed systems limited to one or two interaction modalities. This can make them inaccessible to people with sensory impairments and unable to cope with a dynamic and heterogeneous environment such as the home. This thesis present…
The creative industries sector faces a constantly changing context characterised by the speed of the development and deployment of digital information systems and Information Communications Technologies (ICT) on a global scale. This continuous digital disruption has had signific…
The heart is a fundamental aspect of the human body. Significant work has been undertaken to better understand the characteristics and mechanisms of this organ in past research. Greater understanding of the heart not only provides advances in medicine but also enables practition…
The field of coordinated and multiple views (CMVs) has been for over a decade, a promising technique for enhancing data visualization, yet that promise remains unfulfilled. Current CMVs lack a platform for flexible execution of certain kinds of open-ended tasks consequently user…
The main contribution of this thesis is Secure*BPMN, a graphical security modelling extension for the de-facto industry standard business process modelling language BPMN 2.0.1. Secure*BPMN enables a cognitively effective representation of security concerns in business process mo…
Regular expressions are ubiquitous in computer science. Originally defined by Kleene in 1956, they have become a staple of the computer science undergraduate curriculum. Practical applications of regular expressions are numerous, ranging from compiler construction through smart …
New information and communications technologies, such as mobile phones and social media, have presented the humanitarian community with a dilemma: how should humanitarian organisations integrate information from crisis-affected communities into their decision-making processes wh…
