    Conservative reaction, c.1792-1820: the case for rejection

    No full text
    Conservative writers in Britain articulated a largely hostile attitude towards the United States of America between 1792 and 1820. Having earlier been convinced that an American republic was not viable, they now admitted that there were some reasons to admire its achievements. However, their dominant responses were resentment and contempt. They also felt some apprehension that the United States might prove a stronger and more difficult element in international affairs than they had hitherto expectedStirling University staff and students can access this book in the Library Catalogue: http://libcat.stir.ac.uk/record=b2153040~S

    ‘Glorious Times’: The Emergence of Mechanical Engineering in Early Industrial Britain, c. 1700-1850

    No full text
    The primary aim of this paper is to explore the significance of the emergence and growth of mechanical engineering as a distinct industrial activity in early industrial Britain. The paper provides a survey of the most important interpretations put forward concerning the role of mechanical engineering in the early phases of industrialization. These interpretations are then confronted with data on the growth of the sector and with an analysis of the patterns of innovation carried out by means of a study of patent data. Our results broadly confirm the role of the sector as the main engine of technical progress in this historical phase.Numéro Spécial « Vers une nouvelle histoire économique des brevets ?» Editeurs :Claude Diebolt et Karine Pellierinfo:eu-repo/semantics/publishe

    The Life and Letters of William Sharp and "Fiona Macleod"

    No full text
    "William Sharp (1855-1905) conducted one of the most audacious literary deceptions of his or any time. Sharp was a Scottish poet, novelist, biographer and editor who in 1893 began to write critically and commercially successful books under the name Fiona Macleod. This was far more than just a pseudonym: he corresponded as Macleod, enlisting his sister to provide the handwriting and address, and for more than a decade ""Fiona Macleod"" duped not only the general public but such literary luminaries as William Butler Yeats and, in America, E. C. Stedman. Sharp wrote ""I feel another self within me now more than ever; it is as if I were possessed by a spirit who must speak out"". This three-volume collection brings together Sharp’s own correspondence – a fascinating trove in its own right, by a Victorian man of letters who was on intimate terms with writers including Dante Gabriel Rossetti, Walter Pater, and George Meredith – and the Fiona Macleod letters, which bring to life Sharp’s intriguing ""second self"". With an introduction and detailed notes by William F. Halloran, this richly rewarding collection offers a wonderful insight into the literary landscape of the time, while also investigating a strange and underappreciated phenomenon of late-nineteenth-century English literature. It is essential for scholars of the period, and it is an illuminating read for anyone interested in authorship and identity.

    Index-based triangulation method for efficient generation of large three-dimensional ultrasonic C-scans

    No full text
    The demand for high-speed ultrasonic scanning of large and complex components is driven by a desire to reduce production bottlenecks during the non-destructive evaluation (NDE) of critical parts. Emerging systems (including robotic inspection) allow for the collection of large volumes of data in short time spans, compared to existing inspection systems. To maximise throughput, it is crucial that the reconstructed inspection datasets are generated and evaluated rapidly without loss of detail. This requires new data visualisation and analysis tools capable of mapping complex geometries while guaranteeing full coverage. This paper presents an entirely new approach for the visualisation of threedimensional (3D) ultrasonic C-scans, suitable for application to high data throughput ultrasonic phased array inspection of large and complex parts. Existing reconstruction approaches are discussed and compared with the new index-based triangulation (IBT) method presented. The IBT method produces 3D C-scan representation, presented as coloured tessellated surfaces, and the approach is shown to work efficiently, even on challenging geometries. An additional differentiating characteristic of the IBT method is that it allows for easy detection of lack of coverage (an essential feature for ensuring that inspection coverage can be guaranteed on critical components). The results demonstrate that the IBT C-scan generation approach runs over 60 times faster than a C-scan display based on Delaunay triangulation and over 500 times faster than surface reconstruction C-scans. In summary, the main benefits of the new IBT technique include: high-speed generation of C-scans on large ultrasonic datasets (orders of magnitude improvement compared to surface reconstruction C-scans); the ability to operate efficiently on 3D mapped datasets (allowing 3D interpretation of C-scans on complex geometry components); and intrinsic indication of lack of inspection coverage

    Introducing a new method for efficient visualization of complex shape 3D ultrasonic phased-array C-scans

    Automated robotic inspection systems allow the collection of large data volumes, compared to existing inspection systems. To maximize the throughput associated with the nondestructive evaluation phase, it is crucial that the reconstructed inspection data sets are generated and examined rapidly without a loss of detail. Data analysis often becomes the bottleneck of automated inspections. Therefore, new data visualization tools, suitable to screen the NDT information obtained through robotic systems, are urgently required. This paper presents a new approach, for the generation of three-dimensional ultrasonic C-scans of large and complex parts, suitable for application to high data throughput ultrasonic phased array inspection. This approach produces 3D C-scan presented as colored tessellated surfaces and the approach works efficiently on challenging geometry, with concave and convex regions. Qualitative and quantitative results show that the approach runs up to 500 times faster than other C-scan visualization techniques
