Tsunami Generation By Combined Fault Rupture And Landsliding, Natalia Perez Del Postigo Prieto Jan 2020

Tsunami Generation By Combined Fault Rupture And Landsliding, Natalia Perez Del Postigo Prieto

School of Engineering, Computing and Mathematics Theses

Tsunami generation and propagation mechanisms need to be clearly understood in order to inform predictive models and improve coastal community preparedness. In the last two decades, unexpectedly large tsunamis have devastated localised coastal communities claiming thousands of lives (i.e. the Japan Tsunami of 2011 and Palu Bay Tsunami 2018). An earthquake primarily caused these devastating tsunamis, although the moderate earthquake magnitude for case of (Palu Bay Tsunami 2018), wave directivity and wave arrival time, and extremely large run-up heights in localised areas did not agree with predictions or later tsunami simulations. However, evidence has been later found to suggest that …

Articles

Plasma -generated compounds conceived by microwave -induced plasma (MidiPLexc) were physicochemically investigated in their molecular compositions. Therefore, plasma -treated water (PTW) was generated by treatment with the MidiPLexc within a 1 l glass bottle for a pre -treatment time of 100 s, 300 s and 900 s. The PTW was further investigated in its composition of reactive oxygen/nitrogen species. For this purpose, the hydrogen peroxide (H2O2) concentration of the PTW was determined electrochemically using chronoamperometry, and the anionic components were determined using ion chromatography. As a result, H2O2 concentrations of up to 720 mg l−1 , nitrite concentrations of 1600 …

Knowledge And Behavioural Interventions To Reduce Human Health Risk From Private Groundwater Systems: A Global Review And Pooled Analysis Based On Development Status, S. Mooney, C. P. Mcdowell, J. O'Dwyer, P. D. Hynds

Articles

Groundwater contamination constitutes a significant health risk for private well users residing in rural areas. As the responsibility to safeguard rural private domestic groundwater typically rests with non-expert homeowners, interventions promoting risk mitigation and awareness represent the most viable means of preventing supply contamination. However, no global review or pooled analyses of these interventions has been undertaken to date. The current study sought to identify and quantify the performance of private well interventions from 1990 to 2018 via a global systematised review and pooled analysis. The PICO (Population-Intervention-Comparison-Outcome) approach was employed for literature identification. Relevant studies were statistically analysed across …

Risk Communication Approaches For Preventing Private Groundwater Contamination In The Republic Of Ireland: A Mixed-Methods Study Of Multidisciplinary Expert Opinion, S. Mooney, J. O'Dwyer, Paul Hynds Jan 2020

Risk Communication Approaches For Preventing Private Groundwater Contamination In The Republic Of Ireland: A Mixed-Methods Study Of Multidisciplinary Expert Opinion, S. Mooney, J. O'Dwyer, Paul Hynds

Articles

The mechanisms of private-well groundwater contamination are uniquely complex, necessitating a multisector communicative approach to risk management, premised on behaviour promotion. In countries such as the Republic of Ireland (ROI), characterised by oftentimes high groundwater contamination risk and concurrently limited user awareness, incorporation of multidisciplinary, ‘expert-based’ knowledge may facilitate design of evidence-based, practical interventions. Expert interviews represent an efficient form of expert consultation, enabling ease of access to niche information and comparison of procedure, but remain under-utilised within the groundwater management literature. In response, the current study elicited opinion from 50 experts across four broad categories (communications, engineering/science, policy, and …

Conference papers

Recently, the rapid development of automotive industries has given rise to large multidimensional datasets both in the production sites and after-sale services. Fault diagnostic systems are one of the services that the automotive industries provide. As a consequence of the rapid development of cars features, traditional rule-based diagnostic systems became very limited. Therefore, more sophisticated AI approaches need to be investigated towards more efficient solutions. In this paper, we focus on utilising deep learning so as to build a diagnostic system that is able to estimate the required services in an efficient and effective way. We propose a new model, …

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) …

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 …
