  • Analytic solutions of the magnetic annihilation and reconnection problems. I. Planar flow profiles

    Watson, P.G.; Craig, Ian J.D. (1997-01)
    The phenomena of steady-state magnetic annihilation and reconnection in the vicinity of magnetic nulls are considered. It is shown that reconnective solutions can be derived by superposing the velocity and magnetic fields ...
  • Anisotropic viscous dissipation in compressible magnetic X-points

    Craig, Ian J.D. (E D P Sciences, 2008)
    Context: Visco-resistive damping in line-tied magnetic X-points is examined. Aims: The goal is to determine whether fast, Alfvénic energy dissipation is possible for X-point disturbances damped by the plasma resistivity ...
  • Anisotropic viscous dissipation in three-dimensional magnetic merging solutions

    Litvinenko, Yuri E.; Craig, Ian J.D. (EDP Sciences, 2009)
    Aims: We consider viscous and resistive energy dissipation in the flaring solar corona. Methods: We compute energy dissipation rates, associated with magnetic merging in three dimensions. We examine an exact 3D solution ...
  • Anisotropic viscous dissipation in transient reconnecting plasmas

    Craig, Ian J.D. (EDP Sciences, 2010)
    Aims. We examine the global energy losses associated with reconnecting coronal plasmas. Methods. Using planar magnetic reconnection simulations we compute resistive and bulk viscous losses in transient coronal plasmas. ...
  • Commission 10: Solar Activity

    Melrose, Donald B.; Klimchuk, James A.; Benz, A.O.; Craig, Ian J.D.; Gopalswamy, N.; Harrison, R.A.; Kozlovsky, B.Z.; Poletto, G.; Schrijver, K.J.; Van Driel-Gesztelyi, L.; Wang, J.-X. (Cambridge University Press, 2007)
    Commission 10 aims at the study of various forms of solar activity, including networks, plages, pores, spots, fibrils, surges, jets, filaments/prominences, coronal loops, flares, coronal mass ejections (CMEs), solar cycle, ...

  • Coronal magnetic energy release by current sheet reconnection

    Heerikhuisen, J. (The University of Waikato, 2001)
    In this thesis we investigate the rapid release of energy in the solar corona, with a particular view to understanding the solar flare in which magnetic reconnection is thought to play a key role. A review of existing ...
  • Current sheet formation in uniformly twisted magnetic flux tubes

    Ali, Farhad (The University of Waikato, 2001)
    A viable mechanism for coronal heating is conversion of magnetic field energy into heat through magnetic reconnection in current sheets. Two processes capable of generating current sheets in the solar corona are studied ...
  • Modelling the anaestheto-dynamic phase transition of the cerebral cortex

    Steyn-Ross, D. Alistair (The University of Waikato, 2002)
    This thesis examines a stochastic model for the electrical behaviour of the cerebral cortex under the influence of a general anaesthetic agent. The modelling element is the macrocolumn, an organized assembly of ∼10⁵ ...
  • Geodesic geometry of some static axisymmetric vacuum spacetimes

    Harder, David M. (The University of Waikato, 2003)
    Solutions of Laplace's equation in terms of bispherical and toroidal coordinates are used to derive new exact exterior (vacuum), general relativistic fields, of static axially symmetric spacetimes. For each new metric ...
  • Electromagnetic stirring using a travelling magnetic field

    Saad, Mohd. Noor Bin (The University of Waikato, 2004)
    Electromagnetic stirring of liquid metal is widely used during continuous casting in iron and steel industries to improve the quality of the products. In this thesis we aim to develop a theory for traveling linear stirrers ...
