  • Simulations of 3D Magnetic Merging: Resistive Scalings for Null Point and QSL Reconnection

    Effenberger, Frederic; Craig, Ian J.D. (Springer, 2016)
    Starting from an exact, steady-state, force-free solution of the magnetohydrodynamic (MHD) equations, we investigate how resistive current layers are induced by perturbing line-tied three-dimensional magnetic equilibria. ...
  • D-semigroups and constellations

    Stokes, Tim E. (Springer, 2017)

  • Separation equations for 2D superintegrable systems on constant curvature spaces

    Escobar-Ruiz, M.A.; Kalnins, Ernie G.; Miller, W., Jr. (IOP Publishing Ltd, 2017)
    Second-order conformal quantum superintegrable systems in two dimensions are Laplace equations on a manifold with an added scalar potential and three independent 2nd order conformal symmetry operators. They encode all the ...
  • Estimating the spatial distribution of crime events around a football stadium from georeferenced tweets

    Ristea, Alina; Kurland, Justin; Resch, Bernd; Leitner, Michael; Langford, Chad (MDPI AG, 2018)
    Crowd-based events, such as football matches, are considered generators of crime. Criminological research on the influence of football matches has consistently uncovered differences in spatial crime patterns, particularly ...

    Keegan, Te Taka Adrian Gregory (Te Pua Wānanga ki te Ao / Faculty of Māori and Indigenous Studies, the University of Waikato, 2017)
    This paper considers the usability of the interface and the ramifications for te reo Māori if the interface language, the messages displayed in those text boxes, is written in te reo Māori.
  • Diet selectivity in a terrestrial forest invertebrate, the Auckland tree wētā, across three habitat zones.

    Brown, Matthew; Gemmill, Chrissen E.C.; Miller, Steven D.; Wehi, Priscilla M. (Wiley, 2018)
    Insects are important but overlooked components of forest ecosystems of New Zealand. For many invertebrate species, information on foraging patterns and trophic relationships is lacking. We examined diet composition and ...
