Research outputs 2014 to 2021

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Magneto-optic (MO) imaging and sensing are at present the most developed practical applications of thin-film MO garnet materials. However, in order to improve sensitivity for a range of established and forward-looking applications, the technology and component-related advances are still necessary. These improvements are expected to originate from new material system development. We propose a set of technological modifications for the RF-magnetron sputtering deposition and crystallization annealing of magneto-optic bismuth-substituted iron-garnet films and investigate the improved material properties. Results show that standard crystallization annealing for the as-deposited ultrathin (sputtered 10 nm thick, …

Luxe: Combining High Energy And Intensity To Spark The Vacuum, Beate Heinemann, Tom Heinzl, Andreas Ringwald Jan 2020

Luxe: Combining High Energy And Intensity To Spark The Vacuum, Beate Heinemann, Tom Heinzl, Andreas Ringwald

School of Engineering, Computing and Mathematics

The vacuum of quantum electrodynamics (QED) can be viewed as a medium akin to a dielectric which can be polarised by external fields. If these are sufficiently strong, the response of the vacuum becomes nonlinear and involves phenomena such as lightby- light scattering (‘nonlinear optics’) and, in extremis, ‘dielectric breakdown’, i.e. real pair production, if a critical field strength is exceeded. The LUXE experiment aims to realise near-critical fields through collisions of photons stemming from an ultra-intense optical laser with high energy electrons or photons provided by the European XFEL linear accelerator. This set-up provides a golden opportunity to enter …

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 …

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 …

Deep Learning Towards Intelligent Vehicle Fault Diagnosis, Mohammed Al-Zeyadi, Javier Andreu-Perez, Hani Hagras, Chris Royce, Darren Smith, Piotr Rzonsowski, Ali Malik

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, …

Characterisation Of Crack Tip Fields—Cctf5, Michael Vormwald, Neil James, Youshi Hong, Luca Susmel, Francesco Iacoviello Jan 2020

Characterisation Of Crack Tip Fields—Cctf5, Michael Vormwald, Neil James, Youshi Hong, Luca Susmel, Francesco Iacoviello

School of Engineering, Computing and Mathematics

Single parameter characterisation of the crack/notch tip field using fracture mechanics parameters like K, J, or CTOD has been extremely powerful in advancing predictive technologies for critical or subcritical crack growth. It has also become clear over the last decades that single parameter approaches have limitations particularly in dealing with crack growth phenomena arising from crack tip shielding, often resulting from the plastic enclave surrounding a crack. Influences of this enclave on the crack tip stress field ahead of the crack are maximised during cyclic loading. In the case of a parameter like the stress intensity factor that characterises the …

Weld Solidification Cracking In A 304l Stainless Steel Water Tank, Mn James, L Matthews, Dg Hattingh Jan 2020

Weld Solidification Cracking In A 304l Stainless Steel Water Tank, Mn James, L Matthews, Dg Hattingh

School of Engineering, Computing and Mathematics

Type 304L stainless steel alloy is known to be highly resistant to solidification cracking. In the present case the particular design of the welded seams in a simple 200 litre water tank, along with the likely manner in which the closing welds were made, has led to an interesting example of interdendritic hot cracking in 304L GTA welded using a 309L filler metal. The paper presents a short introduction to hot cracking in austenitic stainless steels and uses the fractographic evidence to demonstrate that this form of cracking has occurred. The cracking has occurred primarily from excessive residual restraint stresses …
