Decision aids to assist Icelandic men with PSA testing and prostate cancer treatment decision-making (2023-09)Prostate cancer (PC) is the second most common cancer among men globally and the most common cancer among Icelandic men. Early detection of PC is possible with a prostate-specific antigen (PSA) test. Before making a decision about PSA testing and before ... -
(2022-12)Concussion symptoms are complex. They are non-specific to a concussion, and there is no gold standard for diagnosis and evaluation. For most, symptoms will resolve in days or weeks following a concussion. However, symptoms can become more serious, ...

(2023-04-17)In this dissertation, we calculate the electronic charge and heat transport generated by a temperature gradient and a chemical potential bias in tubular semiconductor nanowires, in the presence of a magnetic field. We use the Landauer-Büttiker approach ...
-
(2023-06)Crowd simulation focuses on modeling the movements and behaviors of large groups of people. This area of study has become increasingly important because of its several applications in various fields such as urban planning, safety, and entertainment. ...

(2023-04-28)Magnetoresistance oscillations, also known as Shubnikov-de Haas (SdH) oscil- lations, is a well-known phenomena that results from the quantization of electron orbits in the presence of a magnetic field. These oscillations have been extensively studied ...
-
(2023-06-17)Due to changing global circumstances in recent years, Iceland has experienced a sharp increase in forced migrant children, youth, and families seeking refuge. The aim of this doctoral thesis was to examine the migration experience of children and youth ...

(2023-05-22)For machine translation (MT) systems to produce accurate and fluent translations, reliable parallel corpora are key. Errors, due to misalignments or inadequate filtering during compilation of a parallel corpus, can have detrimental effects on the ...
-
(2023-03-31)Nanostructures made from crystalline silicon, especially in the form of nanowires (SiNWs), have shown great potential as pressure sensors due to their unique properties such as high sensitivity, small size, and low power consumption. When a force ...
-
(2023-06-17)The trends afoot for miniaturization of high-frequency electronic devices require integration of active and passive high-frequency circuit elements within a single system. This high level of accomplishment not only calls for a cutting-edge integration ...
-
(2023-03)Machine Learning (ML) is extensively used in diverse healthcare applications to aid physicians in diagnosing and identifying associations, sometimes hidden, between dif- ferent biomedical parameters. This PhD thesis investigates the interplay of ...

(Reykjavik University, 2022-05-13)The recent advances in the development of coding metasurfaces created new opportunities to elevate the stealthiness of combat aircrafts. Metasurfaces, composed of optimized geometries of meta-atoms arranged as periodic lattices, are devised to obtain ...
-
(2023-01)Numerical simulations done at the Nanophysics Center at Reykjavík University indicate that under constant illumination from a sufficiently energetic monochromatic light source, a space-charge limited photoemission can cause current modulation in a ...
-
(2022-12)The dissertation is a collection of the three leading publications, which result from the doctoral research project ‘Sustainable Energy Supply in Remote Arctic Areas - Analysis of resources, technology and policies for developing energy systems’. ...
-
(2022-04)Global climate change is one of the most significant challenges that need urgent action in this century. Energy production and consumption, particularly for heat and electricity generation, account for the highest GHG emissions from anthropogenic ...
-
(2023-01)In this thesis, two methods for automatic enumeration of permutation classes are studied. The first method extends on the theory of combinatorial exploration. We review how combinatorial exploration works as a two phases process: the first phase ...
-
(2023-01)Monitoring brain cortical activity is essential to decipher and understand neurophysiological behaviour. A wide amount of tools and experimental setups has been developed to stimulate, record and analyze brain activity. The identification of ...
