  • Experimental behavior of reinforced concrete beams strengthened with prestressed CFRP shear straps 

    Kesse, GK; Lees, Janet Marillyn (American Society of Civil EngineersJournal of Composites for Construction (ASCE), 2007)
    One promising means of increasing the capacity of existing shear-deficient beams is to strengthen the structure using external prestressed carbon fiber reinforced polymer (CFRP) straps. In this system, layers of CFRP tape ...

  • Experimental characterisation of bubbly flow using MRI

    This thesis describes the first application of ultra-fast magnetic resonance imaging (MRI) towards the characterisation of bubbly flow systems. The principle goal of this study is to provide a hydrodynamic characterisation ...

  • Experimental exploration of fluid-driven cracks in brittle hydrogels 

    O'Keeffe, Niall; Huppert, HE; Linden, Paul Frederick (Cambridge University PressJournal of Fluid Mechanics, 2018-06-10)
    Hydraulic fracturing is a procedure by which a fracture is initiated and propagates due to pressure (hydraulic loading) applied by a fluid introduced inside the fracture. In this study we focus on a crack driven by an ...

  • Experimental investigation of the impact, spreading, and drying of picolitre droplets onto substrates with a broad range of wettabilities 

    Berson, A. (2011-10-02)
    The effect of the substrate wettability on the deposition of picolitre droplets by drop-on-demand technology is investigated experimentally. Substrates with a broad range of wettabilities are considered with contact ...

  • Explaining the CMS eejj Excess With R−parity Violating Supersymmetry and Implications for Neutrinoless Double Beta Decay 

    Allanach, Benjamin Christopher; Biswas, Sanjoy; Mondal, Subhadeep; Mitra, Manimala (American Physical SocietyPhysical Review D, 2015-01-28)
    The recent CMS searches for the right handed gauge boson WR reports an interesting deviation from the Standard Model. The search has been conducted in the eejj channel and has shown an excess around meejj ~ 2 TeV. In this ...
