Effective Online Safety Awareness For Young People In Less Developed Countries, Kona Ramesswar Kona Herkanaidu Jan 2020

Effective Online Safety Awareness For Young People In Less Developed Countries, Kona Ramesswar Kona Herkanaidu

School of Engineering, Computing and Mathematics Theses

In less developed countries (LDCs) there is a research deficit on the positive and negative aspects of their respective emerging digital cultures. Education programmes that seek to raise awareness of online safety, needs to be based on evidence and not simply transposed from other countries as the issues involved may be very different. Thailand, in particular, has very little data that can be used to create meaningful educational material. This was determined after a thorough literature review which found that most of the research has been carried out in the advanced economies of North America, Europe and Australasia. By contrast …


Multi-Modal Personalisation In Long-Term Human-Robot Interaction, Bahar Irfan Jan 2020

Multi-Modal Personalisation In Long-Term Human-Robot Interaction, Bahar Irfan

School of Engineering, Computing and Mathematics Theses

While short-term interactions with robots benefit from the novelty effect, long-term interactions can suffer from a decrease in user interest and engagement. Based on the previous research within Human-Robot Interaction (HRI), the thesis presented here is that user experience in long-term human-robot interactions can be improved by personalising the interaction through recognising users and recalling previously learned information. User recognition is the first step towards personalising the interaction, however, there does not exist a reliable user recognition method for fully autonomous user recognition in long- term HRI for real-world applications. Correspondingly, this thesis proposes a Multi-modal Incremental Bayesian Network (MMIBN) …


The Role And Contribution Of Knowledge And Knowledge Management Practices In Policing. The Case Of An Garda Síochána, Paul Mc Evoy Jan 2020

The Role And Contribution Of Knowledge And Knowledge Management Practices In Policing. The Case Of An Garda Síochána, Paul Mc Evoy

Doctoral

Thisresearch was undertaken in response to knowledge, and particularly knowledge management practice in policing that finds it complex, multifaceted, under researched and lacking in structure and cohesion. This exploratory research sets out to evaluate the role and contribution of knowledge and knowledge management practices in policing, and using An Garda Síochána, (the Police Service ofthe Republic of Ireland), as the underlying case exemplar in this work, it will contribute to the extant literature and understanding in the area by use of a study which contains unprecedented insider access to a modern police force, practical findings for knowledge change predicated on …


Identity As A Service: An Adaptive Security Infrastructure And Privacy-Preserving User Identity For The Cloud Environment, Hoang Tri Vo Jan 2020

Identity As A Service: An Adaptive Security Infrastructure And Privacy-Preserving User Identity For The Cloud Environment, Hoang Tri Vo

School of Engineering, Computing and Mathematics Theses

In recent years, enterprise applications have begun to migrate from a local hosting to a cloud provider and may have established a business-to-business relationship with each other manually. Adaptation of existing applications requires substantial implementation changes in individual architectural components. Existing work has focused on migrating the applications with functional and non-functional aspects. However, none of them has focused so far on the adaptation of the required security infrastructure. On the other hand, users may store their Personal Identifiable Information (PII) in the cloud environment so that cloud services may access and use it on demand. Although cloud services specify …


An Adaptable Interleaved Dc-Dc Boost Converter, Stuart Macveigh Jan 2020

An Adaptable Interleaved Dc-Dc Boost Converter, Stuart Macveigh

School of Engineering, Computing and Mathematics Theses

A.H. Weinberg presented his classic boost topology in his 1974 publication intended for use in satellites. It comprises minimal external components and uses multiple coupled coil systems to provide a boost of up to 2x. Its simplicity makes it inherently robust and reliable as minimal components means lower chance of failure. While its simplicity makes it attractive it has limited boost capability which makes it unsuitable for many modern day applications. No significant investigation has been carried out on adapting the Weinberg topology for high boost operation so far as can be ascertained. An investigation into adapting the Weinberg converter …


Offshore Conversion Of Wind Power To Gaseous Fuels: Feasibility Study In A Depleted Gas Field, P. D. O'Kelly-Lynch, P. D. Gallagher, A. G.L. Borthwick, E. J. Mckeogh, P. G. Leahy Jan 2020

Offshore Conversion Of Wind Power To Gaseous Fuels: Feasibility Study In A Depleted Gas Field, P. D. O'Kelly-Lynch, P. D. Gallagher, A. G.L. Borthwick, E. J. Mckeogh, P. G. Leahy

School of Engineering, Computing and Mathematics

A proof-of-concept study is presented of a Power-to-Gas system that is located fully offshore. This paper analyses how such a system would perform if based at the depleted Kinsale Gas Field in the Celtic Sea Basin off the south coast of Ireland. An offshore wind farm is proposed as the power source for the system. Several conversion technologies are examined in detail in terms of resource efficiency, technological maturity, and platform area footprint, the aim being to ascertain their overall applicability to an offshore Power-to-Gas system. The technologies include proton exchange membrane electrolysers for electrolysis of water to release H2. …

Synthesis And Manufacture Of High Performance Fa-Ggbs-Hmns Based Geopolymer Concrete, Aissa Bouaissi Jan 2020

Synthesis And Manufacture Of High Performance Fa-Ggbs-Hmns Based Geopolymer Concrete, Aissa Bouaissi

School of Engineering, Computing and Mathematics Theses

Geopolymer has received great attention in recent years as a new material that could replace Ordinary Portland cement (OPC) for producing concrete. Geopolymer uses the raw materials rich in aluminium and silicon, which are activated by alkaline solutions to formulate the binder. It has been proven that the geopolymer could be a material capable of providing high-quality properties and having less environmental impact. This research project aims to investigate the capability for producing a geopolymer concrete (GPC) mainly based on the combination of various by-product materials (fly ash, (FA), ground granulated blast-furnace slag (GGBS) and high-magnesium nickel slag (HMNS)) at …


Automotive Cognitive Access: Towards Customized Vehicular Communication System, Muhammad Ahmad Dawood Jan 2020

Automotive Cognitive Access: Towards Customized Vehicular Communication System, Muhammad Ahmad Dawood

School of Engineering, Computing and Mathematics Theses

The evolution of Software Defined Networking (SDN) and Virtualization of mobile Network Functions (NFV) have enabled the new ways of managing mobile access systems and are seen as a major technological foundation of the Fifth Generation (5G) of mobile networks. With the appearance of 5G specifications, the mobile system architecture has the transition from a network of entities to a network of functions. This paradigm shift led to new possibilities and challenges. Existing mobile communication systems rely on closed and inflexible hardware-based architectures both at the access and core network. It implies significant challenges in implementing new techniques to maximize …

Lattice Boltzmann Method For Multiphase Flows With High Density Ratios, Norjan Jumaa Jan 2020

Lattice Boltzmann Method For Multiphase Flows With High Density Ratios, Norjan Jumaa

School of Engineering, Computing and Mathematics Theses

This thesis describes the Lattice Boltzmann Method (LBM) and its application to single and multiphase flows. The LBM algorithm using Single Relaxation Time (SRT) and Multi Relaxation Time (MRT) models are studied. In particular, a new MRT multiphase model is developed, based upon the SRT multiphase model of Banari et al. (2014). A unified LBM approach is used with separate formulations for the phase field, the pressureless Naiver-Stokes (NS) equations and the correction of the pressureless velocity field by solving a Poisson equation. To validate the current model, computations for various Reynolds numbers (Re) were performed to simulate 2D lid …
