  • The effects of an opposing buoyancy force on the performance of an air curtain in the doorway of a building 

    Frank, Daria; Linden, Paul Frederick (ElsevierEnergy and Buildings, 2015-06-01)
    We investigate the effects of an opposing buoyancy force on the performance of an air curtain in the doorway which separates a warm indoor environment from the cold exterior. Such an opposing buoyancy force arises for ...

  • The effects of stochastic forces on the evolution of planetary systems and Saturn's rings 

    Rein, Hanno (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2010-10-12)
    The increasing number of discovered extra-solar planets opens a new opportunity for studies of the formation of planetary systems. Their diversity keeps challenging the long-standing theories which were based on data ...

  • The emergence of shallow easterly jets within QBO westerlies 

    Hitchcocka, P; Haynes, Peter Howard; Randel, WJ; Birner, T (Journal of the Atmospheric Sciences, 2018-01-01)
    © 2018 American Meteorological Society. A configuration of an idealized general circulation model has been obtained in which a deep, stratospheric, equatorial, westerly jet is established that is spontaneously and ...

  • The Evolution of a Supermassive Retrograde Binary Embedded in an Accretion Disk 

    Ivanov, PB; Papaloizou, John Christopher; Paardekooper, S.-J; Polnarev, AG (Open Astronomy, 2015-01-01)

  • The Evolution of Silicon Transport in Eukaryotes 

    Marron, Alan Oliver; Ratcliffe, Sarah; Wheeler, Glen L; Goldstein, Raymond Ethan; King, Nicole; Not, Fabrice; de, Vargas Colomban; Richter, Daniel J (Oxford University PressMolecular Biology and Evolution, 2016-10-11)
    Biosilicification (the formation of biological structures from silica) occurs in diverse eukaryotic lineages, plays a major role in global biogeochemical cycles, and has significant biotechnological applications. Silicon ...

  • The flow of rivers into lakes: Experiments and models 

    Hogg, Charles (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2014-06-12)
    This study considers the motion of river water flowing into a lake. The study has two parts: field observations of an interflowing river in Lake Iseo (Italy); and laboratory experiments on basins fed by an underflow. In ...


  • The fluid mechanics of floating and sinking 

    Vella, Dominic Joseph Robert (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2007-10-02)
    This thesis is concerned with the fluid mechanics of floating and sinking. More specifically, the majority of this thesis considers the role played by surface tension in allowing dense objects to float. We first derive ...

  • The fluxes and behaviour of plumes inferred from measurements of coherent structures within images of the bulk flow 

    Burridge, Henry Charles; Partridge, JL; Linden, Paul Frederick (Taylor & FrancisAtmosphere - Ocean, 2016-06-01)
    This paper describes how measurements of the movement of identifiable features at the edge of a turbulent plume can be interpreted to determine the properties of the mean flow and consequently, using plume theory, can be ...

  • The formation and evolution of reconnection-driven, slow-mode shocks in a partially ionised plasma 

    Hillier, Andrew Stephen; Takasao, S; Nakamura, N (EDP SciencesAstronomy & Astrophysics, 2016)
    The role of slow-mode magnetohydrodynamic (MHD) shocks in magnetic reconnection is of great importance for energy conversion and transport, but in many astrophysical plasmas the plasma is not fully ionised. In this paper, ...

  • The Galilean superstring 

    Gomis, J; Townsend, Paul Kingsley (SpringerJournal of High Energy Physics, 2017-02-21)
    The action for a Galilean superstring is found from a non-relativistic limit of the closed Green-Schwarz (GS) superstring; it has zero tension and provides an example of a massless super-Galilean system. A Wess-Zumino term ...

  • The geometry and representation theory of superconformal quantum mechanics 

    Singleton, Andrew John (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsJesus College, 2016-06-28)
    We study aspects of the quantum mechanics of nonlinear $\sigma$-models with superconformal invariance. The connection between the differential geometry of the target manifold and symmetries of the quantum mechanics is ...

  • The grasshopper problem. 

    Goulko, Olga; Kent, Adrian Patrick (Royal Society of LondonProceedings. Mathematical, physical, and engineering sciences, 2017-11-22)
    We introduce and physically motivate the following problem in geometric combinatorics, originally inspired by analysing Bell inequalities. A grasshopper lands at a random point on a planar lawn of area 1. It then jumps ...

  • The Hindered M1 Radiative Decay Υ(2S) → η_b(1S)γ from Lattice NRQCD 

    Hughes, Ciaran; Dowdall, Rachel J; Davies, Christine TH; Horgan, Ronald Raymond; von, Hippel Georg; Wingate, Matthew Bowen (APSPhysical Review D, 2015-11-03)
    We present a calculation of the hindered M1 Υ(2S) → η_b(1S)γ decay rate using lattice nonrelativistic QCD. The calculation includes spin-dependent relativistic corrections to the NRQCD action through O(v⁶ ) in the quark’s ...

  • The impact and rupture of a water-filled balloon on a rigid surface 

    Lund, Hugh Michael (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2014-06-10)
    The dropping of a water-filled latex balloon onto a flat, rigid surface is an experiment that is known and has been performed by many, but on which there is no existing published work. High-speed images taken of the process ...

  • The Importance of the Unsteady Kutta Condition when Modelling Gust-Aerofoil Interaction 

    Ayton, Lorna Jane; Gill, JR; Peake, Nigel (ElsevierJournal of Sound and Vibration, 2016-06-01)
    The Kutta condition is applied to aerofoils with sharp trailing edges to allow for viscous effects to be considered within a simplified system of equations that are inviscid. This paper discusses in detail the inclusion ...

  • The inclusion of two-loop SUSYQCD corrections to gluino and squark pole masses in the minimal and next-to-minimal supersymmetric standard model: SOFTSUSY3.7
