(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 ... -
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(IEEE, 2022-02-16)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 ...
-
(2020-02-01)Background: Although high-density lipoprotein (HDL) and non-HDL cholesterol have opposite associations with coronary heart disease, multi-country reports of lipid trends only use total cholesterol (TC). Our aim was to compare trends in total, HDL and ... -
(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 ...
-
(University of Iceland, School of Humanities, Faculty of Languages and Cultures, 2022)Abstract Globalization and technological development contribute to an increased demand for English skills in daily recreational activity in Iceland. This phenomenon, and a steadily growing exposure, has changed the status of English in Iceland from ...
-
(University of Iceland, School of Health Sciences, Faculty of Food Science and Nutrition, 2022-06-29)Abstract Background: Hip fractures in older adults are strongly associated with reduced health and quality of life. Loss of bone mass, physical function and muscle mass are thought to be main causes of hip fractures at older age. Associations between ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-06)Biodiversity is declining globally, primarily driven by anthropogenic changes and alterations of natural habitats. In lowland Iceland, human impact has increased considerably in the past decades, often involving an increase in numbers of anthropogenic ...
-
(Elsevier, 2022-07)The atomic scale transitions corresponding to diffusion and interlayer transport of a Au adatom on the low energy, close packed Au(111) surface are studied using density functional theory calculations within the generalized gradient approximation. ...
-
(2021-12-17)Ágrip Doktorsverkefnið er á sviði annarsmálsfræða og hagnýtra málvísinda og beinist að áhrifaþáttum í námi í opnum netnámskeiðum, eða svokölluðum massive open online courses (MOOCs), en með þeim er veittur opinn aðgangur að menntun á ýmsum fræðasviðum ...
-
(Royal Society of Chemistry (RSC), 2022-03-30)Motivated by the use of tetrakis(dimethylamino)silane (TKDMAS) to produce silicon nitride-based deposits and its potential as a precursor for Focused Electron Beam Induced Deposition (FEBID), we have studied its reactivity towards low energy electrons ...
-
(University of Iceland, School of Health Sciences, Faculty of Food Science and Nutrition, 2022-06)Background: Gestational diabetes mellitus (GDM) is one of the most common complications diagnosed in pregnancy and is associated with several adverse outcomes for mothers and their offspring. Several factors, both genetic and environmental, are ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2022)The aims of this project were: 1) to provide data regarding the physical abilities of Icelandic male handball players, by using 9+ screening test. 2) to register prevalence of overuse problems in the knee, low-back and dominant shoulder and to investigate ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2022-06-27)The research described in this thesis is part of a network project involving the growth of metal nanostructures on surfaces of solids, a Horizon 2020 project titled ELENA. The part of the project described here involved the use of various approaches ...
-
(University of Iceland, School of Health Sciences, Faculty of Odontology, 2022-06-21)Background: Good oral health is fundamental for general health, wellbeing and quality of life for all age groups. Little information exists on the oral health of older adults living in Icelandic nursing homes and how they perceive their oral health and ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-06)The theory of divergence by trophic polymorphism, an important part of diversification in vertebrates, has recently been extended to encompass the interplay of developmental, ecological and evolutionary processes (Eco-Evo-Devo dynamics). However, ...
