(University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2020-10-22)The main target of this thesis is to use density functional theory-based simulations to study electrochemical CO2 and N2 reductions by employing a recent theoretical model of an electrochemical solid-liquid interface. This model is used to investigate ... -
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Eng., Mechanical Eng. and Computer Science, 2023-03)The main target of this thesis is to use density functional theory (DFT)-based simulations to study electrochemical CO2 reduction reactions (CO2RR) on transition metal oxides (TMOs) employing thermochemical model and computational hydrogen electrode. ...

Modeling of energy and mass balance using remote sensing for seasonal snow and glaciers in Iceland (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 ...

(MDPI, 2021-05-01)In order to accurately anticipate the proficiency of downdraft biomass gasification linked with a water–gas shift unit to produce biohydrogen, a model based on an artificial neural network (ANN) approach is established to estimate the specific mass ...
-
(Centmapress, 2018)This paper presents a work in progress on the development of a mental model of a food system using system analysis. The aim is to be able to use this model to create a mathematical simulation model that can be used to identify policy intervention ...
-
(2018-06)In the recent years, formal modeling and verification of realtime systems have become very important. Difficult-to-use modeling languages and inefficient analysis tools are the main obstacles to use formal methods in this domain. Timed actor model is ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Eng., Mechanical Eng. and Computer Science, 2024-02)Converting CO2 into value-added products via hydrogenation is of interest due to its potential to reduce and reuse excess atmospheric CO2 and deal with global warming. Metal-organic frameworks (MOFs) are of great interest in this conversion process due ...
-
(Copernicus GmbH, 2018-01-19)Glaciers with extensive surface debris cover respond differently to climate forcing than those without supraglacial debris. In order to include debris-covered glaciers in projections of glaciogenic runoff and sea level rise and to understand the ...
-
(The European Aquaculture Society, 2019)The core objective of VALUMICS project www.valumics.eu is to develop approaches and tools to analyse the structure, dynamics, resilience and impact of food chains on food security, economic development and the environment. This article presents the ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Eng., Mechanical Eng. and Computer Science, 2023-11-30)The effects of global warming are being felt around the world, with extreme weather events occurring ever more frequently. Accelerating the ongoing transition towards renewable energy resources, both in transportation and industry, is of vital ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-12)The population dynamics of marine fish are driven by many top-down and bottom-up processes operating across multiple life-history stages. The majority of teleosts produce large quantities of offspring which experience high mortality rates early in ...
-
(2020)INTRODUCTION According to WHO, midwives are found competent to provide evidencebased and normalcy-facilitating maternity care. Models for midwifery care exist, but seem to be lacking explicit epistemological status, mainly focusing on the practical and ...
-
(Language Centre – University of Cyprus, 2018)The present article deals with the development of basic linguistic terminology in Icelandic. Such terminology pertains to five categories (general, graphematics, phonetics, morphology and lexicon) and has been collected from 19 different sources from ...
-
(Wiley, 2020-06-28)Therapeutic vaccination offers great promise as an intervention for a diversity of infectious and non-infectious conditions. Given that most chronic health conditions are thought to have an immune component, vaccination can at least in principle be ...
-
(American Geophysical Union (AGU), 2015-06-24)The isotopic composition of near surface (or planetary boundary layer) water vapor on the south coast of Iceland (63.83°N, 21.47°W) has been monitored in situ between November 2011 and April 2013. The calibrated data set documents seasonal variations ...
-
(Elsevier BV, 2019-06-15)Molards have been defined in the past as conical mounds of debris that can form part of a landslide's deposits. We present the first conclusive evidence that molards in permafrost terrains are cones of loose debris that result from thawing of frozen ...
-
(IOP Publishing, 2016-08)The hybrid graphene - hexagonal boron nitride (G-hBN) systems offer new routes in the design of nanoscale electronic devices. Using ab initio density functional theory calculations we investigate the dynamics of zig-zag nanoribbons a few interatomic ...
-
(ArXiv, 2016-08)High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission from a prolate spheroidal tip. The space charge limited current is several times lower than the current calculated with ...
-
(2021-08)The study objective was to delineate the genetics of inherited retinal degenerations (IRDs) in Iceland, a small nation of 364.000 and a genetic isolate. Benefits include delineating novel pathogenic genetic variants and defining genetically homogenous ...
