    In urban areas, the issue of resilient-based design for adaptation to climate impacts is one of those where the interdependence between technological innovation, resource governance and sustainable development strategies is relevant. Public spaces are a key system for testing the most effective strategies for reducing climate impacts through approaches that use computational design tools in climate adaptation actions. The paper presents the results of the Athenaeum Research Project funded for 2017-2019 by Federico II University entitled SIMMCITIES_NA, Scenario Impact Modelling Methodology for a Climate change-Induced hazards Tool for Integrated End-users Strategic planning and design - Napoli

    Analysis and correction of the magnetic field effects in the Hybrid Photo-Detectors of the RICH2 Ring Imaging Cherenkov detector of LHCb

    Full text link
    The Ring Imaging Cherenkov detectors of the LHCb experiment at the Large Hadron Collider at CERN are equipped with Hybrid Photo-Detectors. These vacuum photo-detectors are affected by the stray magnetic field of the LHCb magnet, which degrades their imaging properties. This effect increases the error on the Cherenkov angle measurement and would reduce the particle identification capabilities of LHCb. A system has been developed for the RICH2 Ring Imaging Cherenkov detector to perform a detailed characterisation of the magnetic distortion effects. It is described, along with the methods implemented to correct for these effects, restoring the optimal resolution.Comment: 16 pages, 11 figure

    Possible fabrication techniques and welding specifications for the external cylinder of the CMS coil

    Get PDF
    The Compact Muon Solenoid (CMS) is one of the experiments, which are being designed in the framework of the Large Hadron Collider (LHC) project at CERN. The design field of the CMS magnet is 4 T, the magnetic length is 12.5 m and the free aperture is 6 m in diameter. This is achieved with a 4 layer and 5 module superconducting Al- stabilized coil energized at a nominal current of 20 kA at 4.5 K. In the CMS coil the structural function is ensured, unlike in other existing Al-stabilized thin solenoids, both by the Al-alloy reinforced conductor and the external cylinder. The calculated stress level in the cylinder at operating conditions is particularly severe. In this paper the different possible fabrication techniques are assessed and compared and a possible welding specification for this component is given. (9 refs)

    Obiettivo del cluster “Social Housing” ù quello di focalizzare l’attività di ricerca di un numeroso gruppo di ricercatori dell’area della Tecnologia dell’Architettura di diverse Università italiane su un tema progettuale di grande attualità che potrebbe contribuire a qualificare e a rilanciare vaste aree del nostro Paese: la rigenerazione urbana ed ambientale dei quartieri di edilizia residenziale pubblica realizzati tra gli anni Cinquanta e Ottanta nelle prime periferie delle principali città italiane. Si affronta in specifico il tema: Rigenerazione e qualità degli spazi - le prospettive di processo e di intervento, nella prospettiva di di definire linee guida e best practices per ERP e Social Housing attraverso pool di soluzioni innovative e operative in termini complessi di qualità architettonica, utilizzo di energia, prestazioni ambientali, sicurezza, efficienza economica e inclusione sociale
