    Liquid dominated reservoirs are a common type of hydrothermal reservoirs. They consist of fractured rock and reservoir fluid which may obey Darcy’s law. Steam can form in such reservoirs either through heat input which causes temperature increase or ...
  • Sigmundsson, Hermundur; Lorås, Håvard; Haga, Monika (SAGE Publications, 2016-01-25)
    The life span approach to development provides a theoretical framework to examine the general principles of development across all ages (Baltes, Lindenberger, & Staudinger, 2006; Craik & Bialystok, 2006). Previously, developmental research has typically ...
  • Magnússon, Guðmundur; Ólafsson, Sverrir (Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands, 2017-12-19)
    In conventional portfolio management returns are maximised subject to given risk levels. In this framework the only variables of relevance are risk and returns and their interrelationship as expressed in terms of the efficient frontier. It is increasingly ...
  • Magnúsdóttir, Eydís Huld (2019-02)
    Monitoring cognitive workload has the potential to improve both performance and fidelity of individuals facing safety-critical situations in their working environments. Psychophysiological signals, in particular from speech and the cardiovascular system, ...
  • Saavedra, Jose M (Montenegrin Sports Academy, 2018-09-01)
    Training is a complex process that depends, among other factors, on the intensity and volume of training. The objective of this study was to analyse the volume of training in several sports as a function of sex and age. The study sample consisted of ...
  • Edmunds, Kyle Joseph (2017-06)
    The growing field of translational myology continually seeks to define and promote the generalizability of muscle research to clinical practice via optimizing the transition of a wide variety of investigative muscle assessment modalities. There are ...

    We analyze theoretically electronic transport through a core-shell nanowire in the presence of a transversal magnetic field. We calculate the conductance for a variable coupling between the nanowire and the attached leads and show how the snaking ...
