A big data infrastructure for real-time traffic analytics on the cloud
With the increasing urbanisation occurring globally, cities are facing unprecedented challenges. One major challenge is related to traffic and the increasingly common congestion issues that arise in cities. At the same ...
Video surveillance based crowd activity analysis
Video-based crowd motion analysis is an important problem in surveillance applications. Tasks such as identifying anomalous crowd motion patterns, finding sudden changes in the size of a crowd, event detection, and monitoring ...
Towards improving the network architecture of GANs and their evaluation methods
Generative Adversarial Networks (GANs) are a powerful class of generative models. GAN models have recently brought significant success in image synthesis tasks. One key issue concerning GANs is the design of a network ...
Data quality and quantity in mobile experience sampling
The widespread availability of technologically-advanced mobile devices has brought researchers the opportunity to observe human life in day-to-day circumstances. Rather than studying human behaviour through extensive surveys ...
Digital technologies and encounters with zoo animals
Zoos worldwide are beginning to deploy digital technologies for both visitors and animals. Such installations include interactive signage for visitors and touchscreen computers for animal cognition research. Zoos present ...
Dynamic Symbolic Execution with Descriptive and Prescriptive Relations
Static analysis and systematic software testing are two fundamental techniques that aim to ensure software quality. Recently, there has been an obvious interest in exploiting the strengths of these two techniques to work ...
Optimal route planning for hitchhiking
In this thesis, we considered a problem of optimal route planning for hitchhikers. We formalized the hitchhiker's problem and proposed a graph-based model to represent the set of all possible travel options for a hitchhiker. ...
Validating context-driven features of mobile applications using laboratory testing
Mobile devices such as smartphones and tablets now embed a variety of sensors that can provide context-driven services to increasingly large user bases. Driven by the richness of heterogeneous data and machine learning ...
Change Point Detection in High-Dimensional Streaming Time Series Data
In the Internet of Things (IoT), data is continuously recorded from different data sources, such as sensors for monitoring purposes. Some examples of these IoT based sensing platforms are loop detector sensors employed in ...
Exploring knowledge leakage risk in knowledge-intensive organisations: behavioural aspects and key controls
Knowledge leakage poses a critical risk to the competitiveness advantages of knowledge-intensive organisations. Although knowledge leakage is a human-centric security issue, little is known in relation to the key factors ...
