    This paper deals with the development and thetesting of a simulation algorithm for the temperaturebehaviour and the flow characteristics of doublefaçades. It has been developed in order to obtain atool which enables the energy consultant to makequick design decisions without being required to usefairly complicated CFD tools.In order to determine the degree of accuracy of thealgorithm, a double façade has been monitored undercontrolled conditions and the results have beencompared against the predicted values for severaldesign situations. The resulting inaccuracy in somecases can be traced back to how the flow resistanceof various geometries are modelled.

    Climate informed engineering: An essential pillar of industry 4.0 transformation

    Get PDF
    Breakthroughs in computing have led to development of new generations of Earth Systems Models providing detailed information on how our planet may locally respond to the ongoing global warming. Access to such climate information systems presents an unprecedented opportunity for engineers to make tangible contributions to climate adaptation through integration of climate information in their products, designs, and services. We introduce the concept of “Climate Informed Engineering” (CIE) as an emerging interdisciplinary field integrating climatic considerations in engineering products and services. The concept behind CIE is to enable engineers to build infrastructure, devices, sensors or develop new materials and processes that are informed by climate and climate change information. We believe CIE will be an increasingly important dimension of Engineering Science resonating with engineers and scientists with different backgrounds

    Cascading the use of Web 2.0 technology in secondary schools in the United Kingdom: identifying the barriers beyond pre-service training

    This paper reports on research that took place at Nottingham Trent University and Sheffield Hallam University, United Kingdom, over two years. The research focuses on the use of Web 2.0 technology, specifically web logs, with pre-service teachers, both during their university programme and the first year of teaching as full-time newly qualified teachers (NQTs). The purpose of this research was to add a developing body of knowledge by identifying whether technology used by pre-service teachers during their training course can be cascaded into their practice once qualified. Key findings identify a number of enablers and barriers to cascading technology in the classroom; these include curriculum time, pupil skills and support. The research concludes that early professional support and development should be on-going and assumptions about new teachers as champions of cascading innovative use of Web 2 technologies into their practice as NQTs may be over optimisti

    A Factorization Algorithm for G-Algebras and Applications

    Full text link
    It has been recently discovered by Bell, Heinle and Levandovskyy that a large class of algebras, including the ubiquitous GG-algebras, are finite factorization domains (FFD for short). Utilizing this result, we contribute an algorithm to find all distinct factorizations of a given element fGf \in \mathcal{G}, where G\mathcal{G} is any GG-algebra, with minor assumptions on the underlying field. Moreover, the property of being an FFD, in combination with the factorization algorithm, enables us to propose an analogous description of the factorized Gr\"obner basis algorithm for GG-algebras. This algorithm is useful for various applications, e.g. in analysis of solution spaces of systems of linear partial functional equations with polynomial coefficients, coming from G\mathcal{G}. Additionally, it is possible to include inequality constraints for ideals in the input

    Antimicrobial resistance in urosepsis: outcomes from the multinational, multicenter global prevalence of infections in urology (GPIU) study 2003–2013

    Get PDF
    Primary objective was to identify the (1) relationship of clinical severity of urosepsis with the pathogen spectrum and resistance and (2) appropriateness of using the pathogen spectrum and resistance rates of health-care-associated urinary tract infections (HAUTI) as representative of urosepsis. The secondary objective was to provide an overview of the pathogens and their resistance profile in patients with urosepsis. POPULATION AND METHODS: A point prevalence study carried out in 70 countries (2003-2013). Population studied included; 408 individuals with microbiologically proven urosepsis, 1606 individuals with microbiological proof of HAUTI and 27,542 individuals hospitalised in urology wards. Main outcomes are pathogens and resistance identified in HAUTIs and urosepsis including its clinical severity. A statistical model that included demographic factors (study year, geographical location, hospital setting) was used for analysis. RESULTS: Amongst urology practices, the prevalence of microbiologically proven HAUTI and urosepsis was 5.8 and 1.5 %, respectively. Frequent pathogens in urosepsis were E. coli (43 %), Enterococcus spp. (11 %), P. aeruginosa (10 %) and Klebsiella spp. (10 %). Resistance to commonly prescribed antibiotics was high and rates ranged from 8 % (imipenem) to 62 % (aminopenicillin/β lactamase inhibitors); 45 % of Enterobacteriaceae and 21 % of P. aeruginosa were multidrug-resistant. Resistance rates in urosepsis were higher than in other clinical diagnosis of HAUTI (Likelihood ratio <0.05). CONCLUSIONS: It is not appropriate to use the pathogen spectrum and resistance rates of other HAUTIs as representative of urosepsis to decide on empirical treatment of urosepsis. Resistance rates in urosepsis are high, and precautions should be made to avoid further increas

    The Composition of the Modernist Book: Ulysses, A Draft of XXX Cantos and The Making of Americans.

    Get PDF
    This is a study of the composition of three Modernist first editions: Ulysses (1922), The Making of Americans (1925) and A Draft of XXX Cantos (1930). The bibliographical and figurative commitments made to being in print by Ulysses, A Draft of XXX Cantos and The Making of Americans set a coherent program for reading Modernist texts in their perfected form: in print. The editorial reception of the Modernist book has proceeded, however, with reference to the editorial and bibliographical principles established by the New Bibliographers. In deferring to the authors and manuscripts of Modernist books as the highest source of textual authority, the vital significance of being in print to literary Modernism is obscured. The figure of the ideal Book concentrates the central aesthetic, intellectual and bibliographic problem posed the Modernist book: the making of literature. The rhyme with The Making of Americans is appropriate: this book intensifies and consolidates the propositions made about objective and autonomous composition made more hesitantly by Ulysses and A Draft of XXX Cantos. These three books display a gradual refusal to equate inscription and intention; their composition effaces all traces of a sovereign creative subjectivity. The vision of the book guides Modernist composition, and requires a critical distinction be drawn between manuscripts and printed letters. Modernism must be read in print. The vestigial nostalgia for Romantic modes of textual production and creation in Ulysses is repeated on the placards and proof-pages for the book. Printed drafts are revised and reformed by the pen of the author. The finality asserted by the printed letter is only reluctantly ceded on the publication of Ulysses. The composition of A Draft of XXX Cantos represents a further transition away from the script economy of Romanticism. The interplay between authorial typescripts, early publications and the first edition of A Draft of XXX Cantos assert an intermediate order of Modernist textuality which takes the printed page as its foundation. The Making of Americans relies on the absolute objectivity and anonymity of its composition for the effect of its narrative. Objectivity is the intellectual and aesthetic strategy which produces literature rather than the personality and memory of the author. The impersonality of the apparently automatically written manuscripts and scarcely revised typescripts for The Making of Americans severs the visible links between the writing author and her page. In their unwillingness to corroborate the modes of textual generation described by the New Bibliographers, these three books thematise their own composition as the exemplary Modernist and modern mode of textual generation. The Modernist book attenuates or denies a Romantic connection between the creative hand of the author and the surface image of the page: the mechanisms of print deliberately detach the author from the literary text. The distance of the author from the scene of textual reproduction is measured by the printed book. The composition of this analytical object is not a fallacy but an actuality, commemorated in the archive, enacted by the book. Modernism is the literature of the imprimatur rather than of authorial inscription and accordingly it is towards the first editions of Modernist texts that the attentions of editors and textual scholars must be directed
