    We consider the Leader Election Problem in the Signal-to-Interference-plusNoise-Ratio (SINR) model where nodes can adjust their transmission power. We show that in this setting it is possible to elect a leader in two communication rounds, with high ...

    In the present article, we analyze a project in a heavy industry plant in Iceland in which the management aims to hire an equal number of women and men and, thereby, to work against the gender segregation of work. For their efforts, called the 50/50 ...

    Activity space (AS) is a measure of spatial behavior used to summarize the mobility behavior of individuals. Current studies often highlight the fact that AS is highly complex and multidimensional in character. Therefore, the need for more holistic ...
  • Loftsdóttir, Kristín (Informa UK Limited, 2015-10-02)
    This discussion stresses that looking at countries on the margins of European colonial rule can be useful when considering the wider dynamics of the present, reflecting the persistence of colonial discourses and how racism “endures”. Iceland’s colonial ...

    Water isotopes are powerful tracers of the hydrological cycle and can be used to serve many purposes in climateresearch. Here, we use water isotopic measurements – in the vapour and in the precipitations – from Bermudaand Iceland measurement facilities, ...

    We investigate whether one can detect changes in the freshwater contributions to the North Atlantic subpolar gyre(SPG), in light of the observed recent decrease of salinity in the region. We focus on two important conduits offreshwater from the ...
  • Steen-Larsen, H. C.; Sveinbjörnsdóttir, Árný; Jonsson, Th.; Ritter, F.; Bonne, J.-L.; Masson-Delmotte, V.; Sodemann, H.; Blunier, T.; Dahl-Jensen, D.; Vinther, B. M. (American Geophysical Union (AGU), 2015-06-24)
    The isotopic composition of near surface (or planetary boundary layer) water vapor on the south coast of Iceland (63.83°N, 21.47°W) has been monitored in situ between November 2011 and April 2013. The calibrated data set documents seasonal variations ...
  • Stevens, Bjorn; Brogniez, Hélène; Kiemle, Christoph; Lacour, Jean-Lionel; Crevoisier, Cyril; Kiliani, Johannes (Springer Science and Business Media LLC, 2017-07-26)
    In situ, airborne and satellite measurements are used to characterize the structure of water vapor in the lower tropical troposphere—below the height, z∗, of the triple-point isotherm, T∗. The measurements are evaluated in light of understanding of how ...
  • Benetti, Marion; Reverdin, G.; Aloisi, G.; Sveinbjörnsdóttir, Árný (American Geophysical Union (AGU), 2017-06)
    The surface ocean hydrological cycle is explored based on ∼300 new δ18O and δD measurements from surface waters of the Atlantic Ocean and the Mediterranean Sea over the period 2010–2016. Our approach combines these surface observations with salinity ...
  • Benetti, Marion; Lacour, Jean-Lionel; Sveinbjörnsdóttir, Árný; Aloisi, G.; Reverdin, G.; Risi, C.; Peters, A. J.; Steen‐Larsen, H. C. (American Geophysical Union (AGU), 2018-03-10)
    We propose a framework using water vapor isotopes to study mixing processes in the marine boundary layer (MBL) during quiescent conditions, where we expect evaporation to contribute to the moisture budget. This framework complements the existing models, ...
  • Jóhannesson, Ingólfur Ásgeir (University of Wisconsin, 1991)
    This study concerns a reform in elementary education in Iceland, beginning in the late 1960s. The reform has been presented as one of the key links in a chain of projects toward modernizing Iceland, and the educationists who were involved in the reform ...

    North-Atlantic Cold-air outbreaks are weather events characterised by extensive fluxes of latent heat to theatmosphere. Understanding the water budget of these weather events is important for the weather impact indownstream ...
  • Thorhallsson, Andri Isak; Stefansson, Andri; Kovalov, Danyil; Karlsdóttir, Sigrún (Elsevier BV, 2020-05)
    This paper reports the results of corrosion study for carbon steel, austenitic stainless steel, as well as titanium and nickel-based alloys which were tested in a simulated superheated geothermal environment (SSGE) in flow-through reactors to investigate ...
  • Palonen, H.; Magnus, Fridrik; Hjörvarsson, Björgvin (American Physical Society (APS), 2018-10-12)
    The conventional magnetic proximity effect and double-proximity effects were studied in a set of fully coherent high-quality Fe/Fe0.32V0.68 superlattices. Applying a simple model to the saturation magnetization, it is seen that the magnetic proximity ...

    Here we study the magnetic proximity effect in amorphous layered magnets of alternating high- and low-Tc materials using magnetometry and polarized neutron reflectivity. By altering the thickness of either the high- or low-Tc layer we are able to extract ...

    Using a combination of extended X-ray absorption fine structure measurements, stochastic quenching (SQ) calculations and Voronoi tessellation analysis, the local atomic environments in thin films of amorphous SmxCo1−x (x= 0.10, 0.22 and 0.35) are ...
