    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)
    In a result generalising the Ehresmann–Schein–Nambooripad Theorem relating inverse semigroups to inductive groupoids, Lawson has shown that Ehresmann semigroups correspond to certain types of ordered (small) categories he ...
  • Nonlinear Effects in Three-minute Oscillations of the Solar Chromosphere. II. Measurement of Nonlinearity Parameters at Different Atmospheric Levels

    Chae, Jongchul; Cho, Kyuhyoun; Song, Donguk; Litvinenko, Yuri E. (IOP Publishing LTD, 2018)
    Recent theoretical studies suggest that the nonlinearity of three-minute velocity oscillations at each atmospheric level can be quantified by the two independent parameters—the steepening parameter and the velocity amplitude ...
  • Data on coding association rules from an inpatient administrative health data coded by International classification of disease - 10th revision (ICD-10) codes

  • Formal Definitions for Design Spaces and Traces

    Bowen, Judy; Dittmar, Anke (IEEE, 2017)
    Within the domain of interactive system development and design, particularly for safety-critical systems, there is an inherent tension between formalisms used for software engineering methodologies and the creative aspects ...
  • Iwi, institutes, societies & community led initiatives
