Opposition-Based Quantum Bat Algorithm To Eliminate Lower-Order Harmonics Of Multilevel Inverters, Jahedul Islam, Sheikh Tanzim Meraj, Ammar Masaoud, Md Apel Mahmud, Amril Nazir, Muhammad Ashad Kabir, Md Moinul Hossain, Farhan Mumtaz

All Works

Selective harmonic elimination (SHE) technique is used in power inverters to eliminate specific lower-order harmonics by determining optimum switching angles that are used to generate Pulse Width Modulation (PWM) signals for multilevel inverter (MLI) switches. Various optimization algorithms have been developed to determine the optimum switching angles. However, these techniques are still trapped in local optima. This study proposes an opposition-based quantum bat algorithm (OQBA) to determine these optimum switching angles. This algorithm is formulated by utilizing habitual characteristics of bats. It has advanced learning ability that can effectively remove lower-order harmonics from the output voltage of MLI. It can …

Operationalising The Concept Of Ecosystem Collapse For Conservation Practice, Ac Newton, R Britton, K Davies, A Diaz, Dj Franklin, Rjh Herbert, Ra Hill, K Hodder, G Jones, Ah Korstjens, A Lamb, J Olley, Ac Pinder, Cg Roberts, R Stafford

School of Geography, Earth and Environmental Sciences

Concern is growing about ecosystem collapse, namely the abrupt decline or loss of an ecosystem resulting from human activities. While efforts to assess the risk of ecosystem collapse have developed at large spatial scales, less attention has been given to the local scales at which conservation management decisions are typically made. Development of appropriate management responses to ecosystem collapse has been limited by uncertainty regarding how collapse may best be identified, together with its underlying causes. Here we operationalise ecosystem collapse for conservation practice by providing a robust definition of collapse, in a form that is relevant to the scale …

BackgroundNumerous pathologies result in multiple-organ failure, which is thought to be a direct consequence of compromised cellular bioenergetic status. Neither the nature of this phenotype nor its relevance to survival are well understood, limiting the efficacy of modern life-support.MethodsTo explore the hypothesis that survival from critical illness relates to changes in cellular bioenergetics, we combined assessment of mitochondrial respiration with metabolomic, lipidomic and redox profiling in skeletal muscle and blood, at multiple timepoints, in 21 critically ill patients and 12 reference patients.ResultsWe demonstrate an end-organ cellular phenotype in critical illness, characterized by preserved total energetic capacity, greater coupling efficiency and …

Judgemental rationality is infrequently referenced within discussions of Realist Evaluations. Judgemental rationality refers to researchers’ capacity to assess which, potential, meanings provide the most credible explanations. In evaluation work, rationale for analysis is provided, though rarely do we see how an evaluator made judgements between competing theories, and which theories were discarded and why. We provide a worked example of the application of judgemental rationality. The Engager intervention offered support to prison leavers with common mental health problems. The data for 24, purposively sampled, participants from the intervention arm of the trial were integrated. Bhaskar’s DREIC, a five-step analytical procedure, …

Where Are The Children? An Autoethnography Of Deception In Dementia In An Acute Hospital, G Hodge Jan 2021

Where Are The Children? An Autoethnography Of Deception In Dementia In An Acute Hospital, G Hodge

School of Nursing and Midwifery

An acute hospital environment is a confusing place for many patients requiring admission, especially when they are presenting as acutely unwell. This can be particularly difficult for people living with dementia. As cognition changes it is not uncommon for people living with dementia to have difficulties with their ability to orientate to time, place and person. These disorientating moments can lead to personal distress, and at times behavioural changes. As well as being distressing for the person living with dementia, it can also be emotionally and ethically challenging for acute hospital staff; including nurses. One area found to be particularly …

Limitations Of Small-Scale Yielding For Fatigue Crack Growth, B Marques, Mf Borges, Fv Antunes, Jm Vasco-Olmo, Fa Díaz, Mn James

School of Engineering, Computing and Mathematics

The work described here has led to a simple criterion that defines the boundary of the small-scale yielding, SSY, regime to avoid invalid use of the LEFM parameter, ΔK, as the characterising parameter for fatigue crack growth rate. The approach proposed is based on the analysis of crack tip opening displacement, CTOD, and its separation into elastic and plastic components. SSY conditions are shown to dominate when the elastic component of CTOD is >75% of the total CTOD measured at a distance of 8 μm (the finite element mesh size) behind the crack tip, i.e., Δδe/Δδt > 75%. Large-scale yielding, LSY, …

School of Engineering, Computing and Mathematics

Many new developments to detect and mitigate toxicity are currently being evaluated. Weare particularly interested in the correlation between toxicity and the emotions expressed inonline posts. While toxicity may be disguisedby amending the wording of posts, emotionswill not. Therefore, we describe here an ensemble method to identify toxicity and classify the emotions expressed on a corpus ofannotated posts published by Task 5 of SemEval 2021—our analysis shows that the majority of such posts express anger, sadness andfear. Our method to identify toxicity combinesa lexicon-based approach, which on its ownachieves an F1 score of 61.07%, with a supervised learning approach, which …

This paper investigates the effect of varying solid alkali activators on the fresh and hardened properties and microstructural changes of one-part geopolymers (OPGs). Single and binary solid alkali activators were used to activate high calcium fly ash. The alkali activators were either solely sodium metasilicate (Na2SiO3) or a combination of sodium aluminate (NaAlO2) and sodium metasilicate (Na2SiO3). The OPG activated with anhydrous Na2SiO3 achieved an excellent 28-day compressive strength of 83.6 MPa while OPG activated with NaAlO2 and Na2SiO3 attained a compressive strength of 45.1 MPa. The Na2SiO3-activated OPG demonstrated better fluidity than the OPG activated with NaAlO2 and Na2SiO3 …

Facing Up To Climate Change: Community Composition Varies With Aspect And Surface Temperature In The Rocky Intertidal, A. Amstutz, L. B. Firth, J. I. Spicer, M. E. Hanley

School of Biological and Marine Sciences

Marine rocky intertidal organisms are amongst those most affected by climate change with regional distributional changes observed for many species. Although often ascribed to increased sea surface temperatures, precise assessment of the local habitat conditions underpinning observed and predicted changes in community assembly is lacking. Here we examine how aspect (i.e. north-south orientation) affects intertidal community composition and how rock surface temperatures and stress responses of two dominant grazer species (Patella spp.) elucidate emergent differences. We quantified year-round temperature variation and surveyed intertidal community composition on paired natural rock gullies with Equator- (EF) and Pole-facing (PF) surfaces. We also investigated …

School of Biological and Marine Sciences

Data that can be used to monitor biodiversity through time are essential for conservation and management. The reef-forming worm, Sabellaria alveolata (L. 1767) is currently classed as ‘Data Deficient’ due to an imbalance in the spread of data on its distribution. Little is known about the distribution of this species around Ireland. Using data archaeology, we collated past and present distribution records and discovered that S. alveolata has a discontinuous distribution with large gaps between populations. Many regions lack data and should be targeted for sampling. Biodiversity surveys revealed that S. alveolata supported diverse epibiotic algal communities. Retrograding (declining) reefs …
