  • Turbulence ingestion noise of open rotors 

    Robison, Rosalyn Aruna Venner (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-04-10)
    Renewed interest in open rotor aeroengines, due to their fuel efficiency, has driven renewed interest in all aspects of the noise they generate. Noise due to the ingestion of distorted atmospheric turbulence, known as ...

  • Differential systems, moving frames, structure-preserving submersions and geometrical problems in physics 

    Hu, Ziyang (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-07-03)
    The present work applies the theories of exterior differential systems, method of equivalence and moving frames to the study of geometrical problems arising in physics, especially the class of problems that can be described ...

  • Aspects of higher dimensional Einstein theory and M-theory 

    Godazgar, Mohammad Mahdi (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-10-09)
    This thesis contains two main themes. The first is Einstein's theory of general relativity in higher dimensions, while the second is M-theory. The first part of the thesis concerns the use of classification techniques ...

  • Thermodynamic and hydrodynamic behaviour of interacting Fermi gases 

    Goulko, Olga (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-01-10)
    Fermionic matter is ubiquitous in nature, from the electrons in metals and semiconductors or the neutrons in the inner crust of neutron stars, to gases of fermionic atoms, like 40K or 6Li that can be created and studied ...

  • The application of automated perturbation theory to lattice QCD 

    Monahan, Christopher John (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2011-11-08)
    Predictions of heavy quark parameters are an integral component of precision tests of the Standard Model of particle physics. Experimental measurements of electroweak processes involving heavy hadrons provide stringent ...

  • Spiky strings and the AdS/CFT correspondence 

    Losi, Manuel (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2011-10-11)
    In this dissertation, we explore some aspects of semiclassical type IIB string theory on AdS3 × S1 and on pure AdS3 in the limit of large angular momentum S. We first focus on the integrability technique known as ...


  • Tidal interactions between planets and stars 

    Barker, Adrian John (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSelwyn College, 2011-06-07)
    Since the first discovery of an extrasolar planet around a solar-type star, observers have detected over 500 planets outside the solar system. Many of these planets have Jovian masses and orbit their host stars in orbits ...

  • On some partial differential equation models in socio-economic contexts - analysis and numerical simulations 

    Pietschmann, Jan-Frederik (University of CambridgeDepartent of Applied Mathhematics and Theoretical PhysicsTrinity College, 2012-01-10)
    This thesis deals with the analysis and numerical simulation of different partial differential equation models arising in socioeconomic sciences. It is divided into two parts: The first part deals with a mean-field price ...

  • A simple Bayesian estimate of direct RNAi gene regulation events from differential gene expression profiles 

    Wilson, Paul A; Plucinski, Mathew (2011-05-20)
    Abstract Background Microarrays are commonly used to investigate both the therapeutic potential and functional effects of RNA interfering (RNAi) oligonucleotides such as microRNA (miRNA) and small interfering RNA (siRNA). ...


  • Geometric aspects of gauge and spacetime symmetries 

    Gielen, Steffen C. M. (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2011-06-07)
    We investigate several problems in relativity and particle physics where symmetries play a central role; in all cases geometric properties of Lie groups and their quotients are related to physical effects. The first part ...

  • Exploring nonlinear regression methods, with application to association studies 

    Speed, Douglas Christopher (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSt. Catharine's College, 2011-07-12)
    The field of nonlinear regression is a long way from reaching a consensus. Once a method decides to explore nonlinear combinations of predictors, a number of questions are raised, such as what nonlinear combinations to ...

  • Scattering of internal gravity waves 

    Leaman Nye, Abigail (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSelwyn College, 2011-04-19)
    Internal gravity waves play a fundamental role in the dynamics of stably stratified regions of the atmosphere and ocean. In addition to the radiation of momentum and energy remote from generation sites, internal waves ...

  • New approaches to higher-dimensional general relativity 

    Durkee, Mark N. (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2011-06-07)
    This thesis considers various aspects of general relativity in more than four spacetime dimensions. Firstly, I review the generalization to higher dimensions of the algebraic classification of the Weyl tensor and the ...


  • Instabilities and transport in magnetized plasmas 

    Rosin, Mark (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsDarwin College, 2011-02-08)
    In a magnetized plasma, naturally occurring pressure anisotropies facilitate in- stabilities that are expected to modify the transport properties of the system. In this thesis we examine two such instabilities and, where ...

  • Spreading of viscous fluids and granular materials on slopes 

    Takagi, Daisuke (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2010-11-16)
    Materials can flow down a slope in a wide range of geophysical and industrial contexts, including lava flows on volcanoes and thin films on coated surfaces. The aim of my research is to provide quantitative insight into ...

  • The solar tachocline: a self-consistent model of magnetic confinement
