  • Axelsson, Gísli Þór (University of Iceland, School of Health Sciences, Faculty of Medicine, 2022-09)
    Introduction: Interstitial lung diseases (ILD), such as idiopathic pulmonary fibrosis (IPF), are diseases of elderly people that are characterised by pulmonary deposition of fibrous tissue and often have a poor prognosis. Interstitial lung abnormalities ...
  • Bergsten, Pauline (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-09)
    Surtsey is a volcanic island located on the south-east offshore extension of the Icelandic rift zone. It was formed during successive eruptions from the seafloor in 1963-1967 and has been officially protected and studied ever since. It represents ...

    Calculations of societal costs of underweight, overweight and obesity have generally failed to include the value of the utility reductions, associated with deviations from normal weight. To remedy this, the monetary compensation needed to offset the ...
  • Zaqout, Tarek (University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2022-09)
    Sustainable urban drainage systems (SUDS) are increasingly implemented to mitigate flood risk and augment environmental quality and wellbeing in cities. Vegetated swales are one of the most common SUDS components, yet they are among the least studied ...
  • Gunnarsson, Andri (University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2022-09-12)
    Snow and glacier research is important in Iceland for a variety of reasons. Water resource forecasting for hydro-power production is important and monitoring of long-term changes and trends provide guidance for adoption strategies due to climate ...
  • Thorarinsdottir, Kristbjorg Anna (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2022-06-20)
    The work in this thesis is focused on understanding the emergent properties of amorphous magnetic materials. Amorphous materials lack long-range structural ordering, characteristic of crystalline materials. Instead, these materials exhibit medium-to-short ...
  • Guðmundsdóttir, Margrét (University of Iceland, School of Humanities, Faculty of Languages and Cultures, 2022)
    Ágrip: Í rannsókninni Mál á mannsævi er sjónum beint að tilbrigðum í íslenskum framburði, nánar tiltekið eftirtöldum fjórum pörum þar sem fyrrnefnda afbrigðið er sjaldgæfara á landsvísu og útbreiðsla þess að mestu tengd afmörkuðum landsvæðum: ...
  • Guðmundsdóttir, Kristín (University of Iceland, School of Health Sciences, Faculty of Psychology, 2018-12)
    Ágrip Bakgrunnur og meginmarkmið: Markviss og snemmtæk atferlisíhlutun er gagnreynd aðferð sem mælt er með við íhlutun barna með einhverfu og skyldar þroskaraskanir. Hins vegar njóta ekki öll börn og fjölskyldur þeirra slíkrar íhlutunar né þeirrar ...
  • Jóhannsdóttir, Guðrún Helga Diop (University of Iceland, School of Social Sciences, Faculty of Sociology, Anthropology and Folkloristics, 2022-05)
    This doctoral research aims to examine and explain the emerging post-2015 development agenda focusing on the national consultations in Senegal. UN launched and guided the post-2015 development agenda to identify new global policy replacing the Millennium ...

    In this study, recorded empirical data were applied with a practical approach to investigate the optimal tilt angle of the flat plate collectors facing south for a long period in Tehran, Iran. The data included 20 years of recorded average total radiation ...
  • Hassanian, Reza; Riedel, Morris; Yeganeh, Nashmin (Crimson Publishers, 2022-02-23)
    This study aims to consider the Nominal Operating Cell Temperature (NOCT) model for the photovoltaic (PV) module by adding the wind effect via experiment equation. The resulting model presents a linear wind convection heat transfer equation; the PV ...
  • Hassanian, Reza; Riedel, Morris (International Journal of Science and Research (IJSR), 2022-04)
    Because of the mechanical stress importance in the dynamic mechanisms, a Stewart platform is subjected to analysis to extract its critical stress areas in this study. The Stewart platform is an effective mechanism because it has been employed as a ...
  • Hassanian, Reza; Riedel, Morris; Helgadottir, Asdis; Yeganeh, Nashmin; Unnthorsson, Runar (MDPI AG, 2022-02-21)
    This paper evaluates the photovoltaic (PV) module operating temperature’s relation to efficiency via a numerical heat transfer model. The literature reports that higher PV module operating temperatures impact PV module efficiency. There are dozens of ...
  • Hassanian, Reza; Riedel, Morris; Yeganeh, Nashmin (Scientific Research Publishing, Inc., 2022-04)
    This study is aimed to investigate the acceleration response of the non-commutated Direct Current (DC) linear actuator in a numerical approach. The linear actuator is often driven with the specified wave digital signal processing (DSP), which gets ...
  • Jónasdóttir, Rannveig J (University of Iceland, School of Health Sciences, Faculty of Medicine, Faculty of Nursing, 2017-10)
    Background: The physical and psychological health status of patients after intensive care is frequently compromised due to the consequences of critical illnesses and the intensive care stay. There are indications that patients may benefit from receiving ...
  • da Silva, Filipe Ferreira; Cunha, Tiago; Rebelo, Andre; Gil, Adrià; Calhorda, Maria José; García, Gustavo; Ingólfsson, Oddur; Limão-Vieira, Paulo (American Chemical Society (ACS), 2021-03-25)
    Fragmentation of transient negative ions of tryptophan molecules formed through electron transfer in collisions with potassium atoms is presented for the first time in the laboratory collision energy range of 20 up to 100 eV. In the unimolecular ...

    Sound localization is the ability of humans to determine the source direction of sounds that they hear. Emulating this capability in virtual environments can have various societally relevant applications enabling more realistic virtual acoustics. We ...
  • Juhl, Michael; Leosson, Kristjan (American Chemical Society (ACS), 2019-12-20)
    In conventional Stokes polarimetry, where the polarimetric information is obtained from a series of intensity measurements, stable and accurate measurements typically require the optical elements to be carefully designed. Here, we propose a paradigm shift ...
