    Organised by: Cranfield UniversityFirms are urged to constantly introduce new products. Hence, the New Product Development process should be mastered, especially its final phase, the production launch. This paper addresses the critical issue of the information exchange during production launch. Two diagnosis tools considering production launch as a key interface are presented. They permit to examine the information flows, to highlight their weaknesses and hence to find solutions for further improvements. This paper also presents the results of a case study where the diagnosis tools were implemented during a switchgear development project.Mori Seiki – The Machine Tool Compan

    Decay of flux vacua to nothing

    Full text link
    We construct instanton solutions describing the decay of flux compactifications of a 6d6d gauge theory by generalizing the Kaluza-Klein bubble of nothing. The surface of the bubble is described by a smooth magnetically charged solitonic brane whose asymptotic flux is precisely that responsible for stabilizing the 4d compactification. We describe several instances of bubble geometries for the various vacua occurring in a 6d6d Einstein-Maxwell theory namely, AdS_4 x S^2, R^{1,3} x S^2, and dS_4 x S^2. Unlike conventional solutions, the bubbles of nothing introduced here occur where a {\em two}-sphere compactification manifold homogeneously degenerates.Comment: 31 pages, 15 figure

    Total electron scattering cross sections from thiophene for the (1-300 eV) impact energy range

    Get PDF
    Experimental electron scattering cross sections for thiophene in the impact energy range from 1 to 300 eV have been measured with a magnetically confined electron transmission-beam apparatus. Random uncertainty limits have been estimated to be less than 5%, and systematic errors derived from acceptance angle limitations have also been identified and evaluated. Experimental values are compared with our previous low energy (1-15 eV) R-matrix and intermediate/high energy (15-300 eV) IAM-SCAR+I calculations finding reasonable agreement, within the combined uncertainty limits. Some of the low energy shape and core-excited resonances predicted by previous calculations are experimentally confirmed in this study

    Energy harvesting from vehicular traffic over speed bumps: A review

    Get PDF
    Energy used by vehicles to slow down in areas of limited speed is wasted. A traffic energy-harvesting device (TEHD) is capable of harvesting vehicle energy when passing over a speed bump. This paper presents a classification of the different technologies used in the existing TEHDs. Moreover, an estimation of the energy that could be harvested with the different technologies and their cost has been elaborated. The energy recovered with these devices could be used for marking and lighting of roads in urban areas, making transportation infrastructures more sustainable and environmentally friendly

    The link between chemical anomalies along the red giant branch and the horizontal branch extension in globular clusters

    Full text link
    We find a strong correlation between the extension of the Na-O anticorrelation observed in red giant branch (RGB) stars and the high temperature extension of the horizontal branch (HB) blue tails of Galactic globular clusters (GCs). The longer is the O-depleted tail of the Na-O anticorrelation observed in the RGB stars, the higher is the maximum temperature reached by the bluest HB stars in the GC. This result provides a clear, empirical evidence of a link between the extension of the HB and the presence of star-to-star abundance variations of proton-capture elements in GC stars. We discuss the possible interpretation of this correlation.Comment: Comments: 6 pages, 1 figure, uses emulateapj.cls; accepted for publication in the Astrophysical Journal Letter

    Processes of Subjectivation: The Biopolitics and Politics of Literature in the Later Foucault

    Get PDF
    The last few years saw the publication of the lectures given by Michel Foucault at the Collège de France from 1970-71 until the year of his death, 1984. In May 2015, Éditions du Seuil published Théories et institutions pénales (1971-1972), which is the last volume of the series. Knowledge of these published lectures has led to a return to the French thinker’s work and to a transformation of the studies on subjectivity and politics both in literary theory and philosophy. The study of his work, in particular of his later theoretical production and of its reception, is therefore necessary and urgent. This special issue attends the influence of the later Foucault’s legacy, focusing on the central theme of the processes of subjectivation and what are considered to be its two of the most important roots: the literary and the political

    Literature and Politics in the Later Foucault

    Get PDF
    While it has been argued that Foucault’s interest in literature was limited to the 1960s and of a mostly depoliticized nature, the philosopher's previously unpublished later works suggest a different reality, showing a sustained interest in literature and its politics. In the light of this new material, this study repositions Foucault's ideas within recent debates on the politics of literature
