    Jet Engine Exhaust Nozzle Flow Effector

    Get PDF
    A jet engine exhaust nozzle flow effector is a chevron formed with a radius of curvature with surfaces of the flow effector being defined and opposing one another. At least one shape memory alloy (SMA) member is embedded in the chevron closer to one of the chevron's opposing surfaces and substantially spanning from at least a portion of the chevron's root to the chevron's tip

    Developing an e-infrastructure for social science

    Get PDF
    We outline the aims and progress to date of the National Centre for e-Social Science e-Infrastructure project. We examine the challenges faced by the project, namely in ensuring outputs are appropriate to social scientists, managing the transition from research projects to service and embedding software and data within a wider infrastructural framework. We also provide pointers to related work where issues which have ramifications for this and similar initiatives are being addressed

    Argumentum ad misericordiam - the critical intimacies of victimhood

    Get PDF
    This article discusses the widespread use of victim tropes in contemporary Anglo-American culture by using cultural theory to analyse key social media memes circulating on Facebook in 2015. Since the growth of social media, victim stories have been proliferating, and each demands a response. Victim narratives are rhetorical, they are designed to elicit pity and shame the perpetrator. They are deployed to stimulate political debate and activism, as well as to appeal to an all-purpose humanitarianism. Victimology has its origins in Law and Criminology, but this paper opens up the field more broadly to think about the cultural politics of victimhood, to consider how the victim-figure can be appropriated by/for different purposes, particularly racial and gender politics, including in the case of Rachel Dolezal, and racial passing. In formulating an ethical response to the lived experience of victims, we need to think about the different kinds of critical intimacies elicited by such media

    Search for the standard model Higgs boson in the H to ZZ to 2l 2nu channel in pp collisions at sqrt(s) = 7 TeV

    A search for the standard model Higgs boson in the H to ZZ to 2l 2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.Comment: Submitted to JHE
