Automated Identification Of Digital Evidence Across Heterogeneous Data Resources, Hussam J Mohammed

School of Engineering, Computing and Mathematics Theses

Digital forensics has become an increasingly important tool in the fight against cyber and computer-assisted crime. However, with an increasing range of technologies at people’s disposal, investigators find themselves having to process and analyse many systems with large volumes of data (e.g., PCs, laptops, tablets, and smartphones) within a single case. Unfortunately, current digital forensic tools operate in an isolated manner, investigating systems and applications individually. The heterogeneity and volume of evidence place time constraints and a significant burden on investigators. Examples of heterogeneity include applications such as messaging (e.g., iMessenger, Viber, Snapchat, and WhatsApp), web browsers (e.g., Firefox and …

On Lowering The Error Floor Of Short-To-Medium Block Length Irregular Low Density Parity Check Codes, Umar-Faruk Abdu-Aguye

School of Engineering, Computing and Mathematics Theses

Gallager proposed and developed low density parity check (LDPC) codes in the early 1960s. LDPC codes were rediscovered in the early 1990s and shown to be capacity approaching over the additive white Gaussian noise (AWGN) channel. Subsequently, density evolution (DE) optimized symbol node degree distributions were used to significantly improve the decoding performance of short to medium length irregular LDPC codes. Currently, the short to medium length LDPC codes with the lowest error floor are DE optimized irregular LDPC codes constructed using progressive edge growth (PEG) algorithm modifications which are designed to increase the approximate cycle extrinsic message degrees (ACE) …

Improving The Representation Of The Fragility Of Coastal Structures, Robert Jane

School of Engineering, Computing and Mathematics Theses

Robust Flood Risk Analysis (FRA) is essential for effective flood risk management. The performance of any flood defence assets will heavily influence the estimate of an area’s flood risk. It is therefore critical that the probability of a coastal flood defence asset incurring a structural failure when subjected to a particular loading i.e. its fragility is accurately quantified. The fragility representations of coastal defence assets presently adopted in UK National FRA (NaFRA) suffer three pertinent limitations. Firstly, assumptions relating to the modelling of the dependence structure of the variables that comprise the hydraulic load, including the water level, wave height …

Numerical Modelling Of Extreme Waves: The Role Of Nonlinear Wave-Wave Interactions, Thomas Vyzikas

School of Engineering, Computing and Mathematics Theses

The real monsters of the ocean, extreme waves, haunted mariners since the early days of human activities in the sea. Despite having caused numerous accidents and casualties, their systematic study began only in 2000s. Many mechanisms have been proposed to simulate these rare but catastrophic events, with the most prominent being wave focusing. This is connected to the NewWave theory, which has been used extensively in experimental and numerical modelling. However, the majority of the studies fail to capture the distinguishing characteristics of extreme waves, due to the inherent high nonlinearity of the problem and shortcomings of the modelling practice, …

Contesting Early Childhood Professional Identities: A Cross-National Discussion, Sonja Arndt, Mathias Urban, Colette Murray, Kylie Smith, Beth Swadener, Tomas Ellegaard

Articles

In this collective article, the authors explore constructions of early childhood practitioners and how they disconnect and reconnect in a global neo-liberal education policy context. The contributions to the conversation provide windows into shifting professional identities across five national contexts: New Zealand, the USA, Ireland, Australia and Denmark. The authors ask who benefits from the notion of distinct professional identities, linked to early childhood education as locally and culturally embedded practice. They conceptualize teachers’ shifting subjectivities, drawing on Kristeva’s philosophical conception of identity as constantly in construction, open and evolving. Arguments for the urgency to counter the global uniformity machine, …

Teaching Robots Social Autonomy From In Situ Human Supervision, Emmanuel Senft

School of Engineering, Computing and Mathematics Theses

Traditionally the behaviour of social robots has been programmed. However, increasingly there has been a focus on letting robots learn their behaviour to some extent from example or through trial and error. This on the one hand excludes the need for programming, but also allows the robot to adapt to circumstances not foreseen at the time of programming. One such occasion is when the user wants to tailor or fully specify the robot’s behaviour. The engineer often has limited knowledge of what the user wants or what the deployment circumstances specifically require. Instead, the user does know what is expected …

Taxation For Whom?:A Diachronic Analysis Of Taxation In Ireland And The United Kingdom From 1970-2015., Ewan Macdonald, John Hogan, Brendan O'Rourke

Other

This paper explores the discursive development of taxation within budget speeches in two countries, the Republic of Ireland and the United Kingdom, from 1970 to 2015 by means of a corpus-assisted discourse analysis. We ask the following questions; how have discourses of taxation developed diachronically in both countries, what are the similarities and differences in the observable discourses across both countries, and for whom and how are these discourses legitimised? In answering these questions, this paper makes use of Corpus linguistics, a methodological approach which utilises computational analysis of large bodies of text to draw statistically significant conclusions about the …

Understanding How Immigrant Entrepreneurs View Business Opportunity Formation Through Ethnicity, Kingsley C. Njoku, Thomas M. Cooney

Books/Book Chapters

Given that international research is now consistently showing higher rates of entrepreneurial activity from immigrants above native people, research regarding our understanding of how immigrant entrepreneurs view business opportunity formation remains underdeveloped. Based upon a review of the literature, this chapter examines how ethnicity relates to business opportunity formation through constant interactions. It also introduces the Visual Mixed Embeddedness Framework as an empirical lens for understanding the differences in the business opportunity formation process models between immigrant and native entrepreneurs. By explaining how factors and traits from both home and host countries impact upon the immigrant entrepreneurial business activity process, …
