    A fundamental requisite for genetic studies is an accurate determination of sequence variation. While human genome sequence diversity is increasingly well characterized, there is a need for efficient ways to utilize this knowledge in sequence analysis. ...
  • McKelvey, Maureen; Saemundsson, Rognvaldur (Informa UK Limited, 2020-06-28)
    The purpose of this article is to better understand the challenges of avoiding the dark side of technological innovation. Specifically, we analyse 10 public investigations started as a reaction to a major crisis in regenerative medicine at the Karolinska ...
  • Shimomura, Yayoi; Hvannberg, Ebba Thora; Hafsteinsson, Hjálmtýr (Springer Nature, 2012-03-17)
    Research has been conducted on how to aid blind peoples’ perceptions and cognition of scientific data and, specifically, on how to strengthen their background in mathematics as a means of accomplishing this goal. In search of alternate modes to vision, ...
  • Atlason, Reynir Smari; Oddsson, Gudmundur V.; Unnthorsson, Runar (Springer Nature, 2017-09-07)
    Heat pumps use the temperature difference between inside and outside areas to modify a refrigerant, either for heating or cooling. Doing so can lower the need for external heating energy for a household to some extent. The eventual impact depends on ...
  • Karlsdottir, Marta (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2021-06)
    Geothermal energy utilization contributes to less than 0.5% of the world’s electricity demand and is not well represented in energy policies and environmental studies of energy systems. Research on geothermal potential and environmental impacts shows ...
  • Karlsdóttir, Marta Rós; Heinonen, Jukka; Pálsson, Halldór; Pálsson, Ólafur Pétur (MDPI AG, 2020-06-19)
    The European Union (EU) has made climate change mitigation a high priority though a policy framework called "Clean Energy for all Europeans ". The concept of primary energy for energy resources plays a critical role in how different energy technologies ...
  • Safarian, Sahar; Unnthorsson, Runar; Richter, Christiaan (Informa UK Limited, 2021-02-28)
    This study develops a new simulation model by ASPEN Plus for gasification integrated with water-gas shift reactors and product recovery unit for hydrogen production. Timber and wood waste (T&WW) as a lignocellulosic biomass was also considered as the ...
  • Hassanian, Reza; Helgadóttir, Ásdís; Riedel, Morris (Elsevier, 2023-02-21)
