Mobile Exam System – MES: Architecture for Database Management
No full textAs the mobile applications are constantly facing a rapid development in the recent years especially in the academic environment such as student response system (Lópeza, Royoa, Labordab & Calvoa, 2009; Ngai & Gunasekaran, 2007; Mary & Biju, 2008; Nayak & Erinjeri, 2008; Roth, Ivanchenko & Record, 2008; Lu, Stav & Pain, 2009; Lu, 2009; Turning technologies, 2010) used in universities and other educational institutions; there has not been reported an effective and scalable Database Management System to support fast and reliable data storage and retrieval. This paper presents Database Management Architecture for an Innovative Evaluation System based on Mobile Learning Applications. The need for a relatively stable, independent and extensible data model for faster data storage and retrieval is analyzed and investigated. It concludes by emphasizing further investigation for high throughput so as to support multimedia data such as video clips, images and documents
Techno-economic transition towards a hydrogen economy
No full textPhDThe research conducted is in the field of innovation and focuses on the UK energy sector. The key theme of the study is the transition towards a hydrogen economy with fuel cell technologies at the epicentre and takes into account the relevant scientific, technological, economic and policy issues. In order to provide an understanding of the factors that affect techno-economic transitions to alternative energy systems, the thesis investigates the historical transition processes such as the transition to electrification in the early 1900s and recent transitions to CCGT and renewable energy systems (wind, biofuels and solar) that have taken place since the late 1980s. As the developmental status of hydrogen technologies lay at the heart of these transitions, a thorough analysis of the hydrogen and fuel cell technologies, the R&D requirements, and innovations required in different scientific fields (including materials science) to develop these technologies is conducted. At the same time, as other factors such as sustainability, climate change and security of supply concerns can greatly affect the direction of the transition processes, that includes R&D activities and investment in alternative energy technologies, an overview of these factors is also provided. The analysis employs a new theoretical framework that combines two well established theories in the literature, Techno-economic Transitions and Large Technological Systems. By using this new framework, the technological transition towards a hydrogen energy system can be analysed at three levels, (global, national and local). The analysis is narrowed down to the local level in order to determine the timing of a transition in London and how it can form the foundation for a wider a transition at the national level based on alternative technologies
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters

Lipoxygenase-derived eicosanoids in myocardial ischaemia-reperfusion injury: the role of sensory C-fibres and TRPV1
No full textPhDIt is well established that the 12-lipoxygenase (12-LOX) pathway of arachidonic acid (AA) metabolism is stimulated within the myocardium by episodes of ischaemia, and there is considerable evidence showing that eicosanoids derived via this pathway protect against the damaging effects of myocardial ischaemia-reperfusion (I/R) injury. Recent evidence suggests that transient receptor potential vanilloid receptor 1 (TRPV1), expressed on sensory C-fibres, may play an important protective role against myocardial I/R injury; and in neurones, the 12-LOX metabolite of AA 12(S)-hydroperoxyeicosatetraenoic acid [12(S)-HpETE], has been proposed as an endogenous ligand for TRPV1. However, whether 12(S)-HpETE underlies TRPV1 channel activation during myocardial I/R is unknown.
Treatment of isolated Langendorff rat hearts with 12-LOX/AA significantly attenuated I/R injury (~40% inhibition of infarct size), an effect reversed by the 12-LOX inhibitor baicalein or by chemical desensitisation of local C-fibre afferents in vivo using capsaicin. Both 12(S)-HpETE and AA caused dose-dependent coronary vasodilatation (~pEC50s of 18.2 and 6.9, respectively) that was profoundly suppressed by the TRPV1 antagonist capsazepine, or in hearts of TRPV1 knockout mice compared to wild-type mice, or by treatment with the calcitonin gene-related peptide (CGRP) receptor antagonist, CGRP8-37. I/R in vitro reduced expression of myocardial TRPV1 protein, whereas in vivo, TRPV1 protein expression in the heart and dorsal root ganglia (DRG) increased, and DRG TRPV1 messenger ribonucleic acid levels decreased – suggesting that whilst TRPV1 protein may be down-regulated during I/R in vitro, when neurones innvervating the heart are associated with their cell bodies, TRPV1 expression may be increased, possibly under the control of neurotrophic factors.
Together, the findings from this thesis identify a novel 12-LOX/AA/TRPV1 pathway activated and up-regulated during myocardial I/R injury, providing an endogenous damage-limiting mechanism – the targeting of which may prove useful in treating myocardial infarction or protecting against I/R injury associated with common surgical procedures including cardiac transplantation
Consequences for lotic ecosystems of invasion by signal crayfish
No full textPhDNon-native invasive species are major drivers of biodiversity loss and ecosystemlevel
modification. The signal crayfish (Pacifastacus leniusculus) is a highly
successful invasive species and demonstrates traits often seen in keystone species,
including top-down predatory effects, a high degree of omnivory, and an ability to
physically modify its habitat. From field surveys, and in situ and artificial channel
experiments, I show that signal crayfish have direct and indirect impacts on the
benthos, as well as ecosystem process rates, in lowland, chalk stream ecosystems.
Furthermore, I show that these effects are often dependent on crayfish life stage. I
demonstrate that two native fish species (chub, Leuciscus cephalus and bullhead,
Cottus gobio) may be affected positively, as well as negatively, by signal crayfish
invasion. In addition, population genetics reveals overall high levels of genetic
diversity in populations of signal crayfish in the UK.Funding awarded by Queen Mary University of London

Ketchup and Blood: Documents, Institutions and Effects in the Performances of Paul McCarthy 1974-2013
No full textSince the 1970s, the work of Los Angeles-based artist Paul McCarthy (b. 1945) has included live performance, video, sculpture, kinetic tableaux, and installation. Tracing the development of McCarthy’s work between 1974 and 2013, I undertake a critical discussion of the development of performance in relation to visual art practices. Using one artist’s work as a guide through a number of key discussions in the history of performance art, I argue that performance has influenced every aspect of McCarthy’s artistic practice, and continues to inform critical readings of his work.
My thesis follows the trajectory of McCarthy’s performance practice as it has developed through different contexts. I begin with the early documentation and dissemination of performance in the Los Angeles-based magazine High Performance (1978-83), which established a context for the reception of performance art, and for McCarthy’s early work. I then examine specific examples of McCarthy’s practice in relation to his critical reception: live performances and videos from the 1970s are discussed alongside critical readings of his work influenced by psychoanalysis; and the wider public recognition of McCarthy’s object-based art in the 1980s and early 1990s. I then look more broadly at the recent trend of re-enacting historical performances in the Getty’s Pacific Standard Time project (2011-12), as a mode of engaging with performance history and exploring how histories of ephemeral art are re-iterated over time. Finally, I discuss a number of McCarthy’s recent exhibitions and installations that mobilises a wider consideration of the histories of performance and ephemeral practices in art institutions.
McCarthy’s work is firmly established in the art world, and I argue that his work also provides a significant touchstone for histories of performance. I look historically at how McCarthy’s work has been documented, disseminated, curated, and re-performed, and open wider discussions about ways of engaging with performance history. In turn, I complicate the relationship between performance and the art world; between ephemeral art and object-based art practices; and between scholarly engagements with performance history, and the public presentation of performance in curatorial practices and institutional contexts.This project was funded by a College Studentship from Queen Mary, University of London. Additional financial support for a research trip to Los Angeles in 2012 to undertake primary research and conduct interviews was provided by the Queen Mary Central Research Fund (now the Postgraduate Research Fund). I would also like to acknowledge the support of the Glynne Wickham Scholarship fund, which contributed to travel expenses for a conference presentation at Stanford University in 2013
