Contextual mobile adaptation
Ubiquitous computing (ubicomp) involves systems that attempt to fit in with users’ context and interaction. Researchers agree that system adaptation is a key issue in ubicomp because it can be hard to predict changes in contexts, needs and uses. Even with the best planning, it is impossible to …

Understanding and improving the identification of concurrently presented earcons
The use of sound to communicate information as part of a user interface has been an active research area for several years. Research has shown that sound can be concurrently presented to users to increase the bandwidth and rate of data presentation. However, when sounds are concurrently presented, …

Algorithmic aspects of stable matching problems
The Stable Marriage problem (SM), the Hospitals/Residents problem (HR) and the Stable Roommates problem (SR) are three classical stable matching problems that were first studied by Gale and Shapley in 1962. These problems have widespread practical application in centralised automated matching …

Parameterised verification of randomised distributed systems using state-based models
Model checking is a powerful technique for the verification of distributed systems but is limited to verifying systems with a fixed number of processes. The verification of a system for an arbitrary number of processes is known as the parameterised model checking problem and is, in general, …
