    Modelling and evaluation of pulsed and pulse phase thermography through application of composite and metallic case studies

    No full text
    A transient thermal finite element model has been created of the pulsed thermography (PT) and pulse phase thermography (PPT) experimental procedure. The model has been experimentally validated through the application of four case studies of varying geometries and materials. Materials used include aluminium, carbon fibre reinforced plastic (CFRP) and adhesively bonded joints. The same four case studies have also formed a basis for comparison between three experimental techniques: PT, PPT and the more established ultrasonic (UT) c-scan.Results show PPT to be advantageous over PT due to its deeper probing as it is less influenced by surface features. Whilst UT is able to reveal all the defects in these case studies, the time consuming nature of the process is a significant disadvantage compared to the full field thermography methods.Overall, the model has achieved good correlation for the case studies considered and it was found that the main limiting factor of the PT model accuracy was knowledge of thermal material properties such as conductivity and specific heat. Where these properties were accurately known the model performed very well in comparison with experimental results. PPT modelling performed less well due to the method of processing the PT data which aims to emphasise small differences. Hence inaccuracies in inputted values such as material properties have a much greater influence on the modelled PPT data. The model enables a better understanding of PT and PPT and provides a means of establishing the experimental set-up parameters required for different components, allowing the experimental technique to be appropriately tailored to more complex situations including bonded joints or structures where several materials are present.The paper ends with a section on defect detectability based on thermal diffusivity contrast between the defect and the bulk material. It shows that in aluminium, because of its higher conductivity, greater thermal contrast is achieved for small differences in diffusivity. Regions where the diffusivity ratio between defect and bulk materials was insufficient to provide thermal contrast for defect identification were found. PPT phase data is shown to reduce the extent of such regions increasing the detectability of defects. Effusivity is introduced as a means of determining the thermal contrast between the defect and non-defective areas and hence establishing the defect detectability

    The voice of authority : Evelyn Waugh's fiction

    No full text
    A large part of the extant criticism of Evelyn Waugh's fiction is orientated towards either a biographical or a literary-historical interest: there are comparatively few detailed surveys of the novels themselves. This study attempts such a survey, and in particular examines the tension which inheres in the relationship of Waugh's poised, urbane narrators to the social and moral chaos they depict. I have been interested in the source and management of that poise, the testing, as it were to destruction, of a series of narrative positions. There is a very modern equation to be observed in Waugh's fiction, between the potentially anarchic mode of fiction and what Waugh felt to be the actual anarchy of contemporary civilisation. His novels can with interest be read in terms of a comic exploitation of this equation, and subsequently, as the writer aged, of his attempts to evade its logic, to discover a 'voice of authority'. Apparently secure narrative stances are repeatedly undermined, and a succession of 'realities' compromised - Tony Last's, William Boot's, John Plant's, Guy Crouchback's. It is this awareness and exploitation of the reflexive quality of fiction, and its use in disclosing the nature of his age which lends Waugh's writing its real and enduring interest. I seek to draw out this awareness through detailed examination of the different novels' precise narrative stance, the source of their 'voice', and have been largely content to let stand other commentators' descriptions of Waugh's broader thesis. My method involves close attention to Waugh's language, from the conviction that nuances of tone and the development of marginal allusions and metaphors are the keys to many of his characteristic effects

    Dasyhelea pseudoincisurata Waugh & Wirth Dasyhelea pseudoincisurata Waugh & Wirth, 1976: 233 (Georgia; New Hampshire south to Florida); Borkent & Grogan 2009: 11 (in Nearctic catalog; distribution). Diagnosis. This is a large dark brown species, male wing length 1.10–1.50 mm, female wing length 1.20–1.47 mm; femora and tibiae usually with broad dark brown bands. Males with posterior margin of sternite 9 straight to slightly concave; tergite 9 tapered distally with straight posterior margin and elongate, cylindrical, divergent apicolateral processes; gonocoxite usually with short basomesal spur; gonostylus slightly curved, pubescent except apical portion, and tip usually notched. Female subgenital plate with slender, elongate anterior portion, posterior portion broader with curved lateral arms; and spermatheca subspherical with retort-shaped neck. Discussion. Waugh & Wirth (1976) described this species from the eastern United States based on specimens from Florida, Georgia (type locality), Maryland, New Hampshire, Pennsylvania and Virginia. In their Nearctic catalog, Borkent & Grogan (2009) also listed it from Utah and Ontario, Canada. We identified a male from Guadeloupe as this species that we compared with a male paratype from Georgia and several other males from Florida and Maryland. We provide the first record of this species in the Caribbean region from Guadeloupe. Material examined. Guadeloupe, Basse Terre, La Trace du Petit-Malendure, 21-V-2012, R. H.

    Bayesian Variations on the Frisch and Waugh Theme

    No full text
    The paper is devoted to discussing consequences of the so-called Frisch-Waugh Theorem to posterior inference and Bayesian model comparison. We adopt a generalised normal linear regression framework and weaken its assumptions in order to cover non-normal, jointly elliptical sampling distributions, autoregressive specifications, additional nuisance parameters and multi-equation SURE or VAR models. The main result is that inference based on the original full Bayesian model can be obtained using transformed data and reduced parameter spaces, provided the prior density for scale or precision parameters is appropriately modified.Bayesian inference, regression models, SURE models, VAR processes, data transformations
