    Juvenile pyroclasts, especially in the ash size range, provide important information on primary fragmentation processes, i.e., initial explosive magma fragmentation, and on the state of the magma both prior to and at the point of fragmentation and ...

    The morphological and textural features of juvenile pyroclasts record crucial details on magma conditions at the time of fragmentation. Their study is therefore essential to better understand the dynamics of explosive eruptions. Unfortunately, the ...

    The habit of the common starling (Sturnus vulgaris) to associate with grazing horses is spreading in Iceland. When asked I found that many thought the birds were picking parasites from the skin of the horses. I found no references to scientific papers ...

    The aim of genome-wide association studies (GWAS) is to identify sequence variants that influence human traits or diseases. Previous GWAS have mostly focused on finding variants that affect the mean of a trait or disease risk under an additive model. ...

    Forecasting of glacier mass balance is important for optimal management of hydrological resources, especially where glacial meltwater constitutes a significant portion of stream flow, as is the case for many rivers in Iceland. In this study, a method ...
  • Pezzutto, Simon; De Felice, Matteo; Fazeli, Reza; Kranzl, Lukas; Zambotti, Stefano (MDPI AG, 2017-08-23)
    This study fills in knowledge gaps for the European air-conditioning (AC) market, which is fundamentally important to raising awareness about primary energy utilization. In contrast to space heating (SH) and domestic hot water (DHW) preparation, the ...
  • Burger, Jan David (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021)
    In the ΛCDM concordance model cold and collision-less dark matter (CDM) accounts for about four fifths of the Universe’s total matter content, while visible baryonic matter makes up the final fifth. The ΛCDM model successfully describes how large ...

    We present, in this paper, a new methodology for spectral unmixing, where a vector of fractions, corresponding to a set of endmembers (EMs), is estimated for each pixel in the image. The process first provides an initial estimate of the fraction vector, ...
