Optimal atomic structure of amorphous silicon obtained from density functional theory calculations (IOP Publishing, 2017-06-15)Atomic structure of amorphous silicon consistent with several reported experimental measurements has been obtained from annealing simulations using electron density functional theory calculations and a systematic removal of weakly bound atoms. The ... -
(American Physical Society (APS), 2021-04-29)A complete analytical solution to the optimal reversal of a macrospin with easy-axis anisotropy is presented. An optimal control path minimizing the energy cost of the reversal is identified and used to derive the time-dependent direction and amplitude ...
-
(American Physical Society (APS), 2022-04-07)It is demonstrated by means of the optimal control theory that the energy cost of the spin-orbit torque induced reversal of a nanomagnet with perpendicular anisotropy can be strongly reduced by proper shaping of both in-plane components of the current ...

(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 ...

(Menntavísindasvið, Menntavísindastofnun Háskóla Íslands, 2018-12-31)Greinin fjallar um orðaforðahluta rannsóknar á þróun máls og læsis meðal íslenskra barna á aldrinum 4 til 8 ára. Um er að ræða viðamikla langtímarannsókn á flestum þáttum málþroska og tengslum hans við þróun læsis og félagsþroska. Til að bæta úr skorti ...

(School of Education, University of Iceland, 2023-10-03)This thesis focuses on the external evaluation of compulsory schools in Iceland. Aligned with that focus, the aim of the research conducted for the thesis was twofold: first, to shed light on the origin of the external evaluation of compulsory schools ...

Origins of the Greenland shark (Somniosus microcephalus): Impacts of ice-olation and introgression (Wiley-Blackwell, 2017-09-08)erein, we use genetic data from 277 sleeper sharks to perform coalescent-based modeling to test the hypothesis of early Quaternary emergence of the Greenland shark (Somniosus microcephalus) from ancestral sleeper sharks in the Canadian Arctic-Subarctic ...
-
(University of Iceland, School of Humanities, Faculty of History and Philosophy, 2014)Osteoarthritis has been intensively studied within the field of palaeopathology. For decades there was assumed to be a direct link between activity and the development of osteoarthritis, and this was reflected in the work which was carried out, with ...

(University of Iceland, School of Health Sciences, Faculty of Medicine, 2017-06)Lung cancer is the third most common type of cancer and the prime cause of cancer-related deaths in Iceland. As surgical resection is the only well-defined and well-studied curative treatment, the aim is to offer surgery to as many patients as possible ...

(University of Turku; University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2020-11-13)Tephrochronology is a high-precision dating method that uses volcanic ash horizons as isochrons in correlating and dating geological records and archaeological sites. First developed in the volcanic regions of the world, tephrochronology has expanded ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021-05)In this thesis, we explore the role of symmetries in hydrodynamics by studying certain properties of relativistic and non-relativistic fluids. In the first part of the thesis, we examine the theory of relativistic magnetohydrodynamics (Maxwell ...
