(MDPI AG, 2019-01-10)In this paper, we develop a hyperspectral feature extraction method called sparse and smooth low-rank analysis (SSLRA). First, we propose a new low-rank model for hyperspectral images (HSIs) where we decompose the HSI into smooth and sparse components. ... -
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Electrical and Computer Engineering, 2021-12-16)Hyperspectral images (HSIs) acquired by hyperspectral imaging sensors contain hundreds of spectral bands. The abundant spectral information provided by an HSI makes it possible to discriminate different materials in a scene. Therefore, HSIs have ...

(Institute of Electrical and Electronics Engineers (IEEE), 2018)Hyperspectral image (HSI) is usually corrupted by various types of noise, including Gaussian noise, impulse noise, stripes, deadlines, and so on. Recently, sparse and low-rank matrix decomposition (SLRMD) has demonstrated to be an effective tool in ...

(Institute of Electrical and Electronics Engineers (IEEE), 2018)In this paper, we present a deep learning based method for blind hyperspectral unmixing in the form of a neural network autoencoder. We show that the linear mixture model implicitly puts certain architectural constraints on the network, and it effectively ...

Hypertrophic cardiomyopathy in myosin-binding protein C (MYBPC3) Icelandic founder mutation carriers (BMJ, 2020-04-05)Objective The myosin-binding protein C (MYBPC3) c.927-2A>G founder mutation accounts for >90% of sarcomeric hypertrophic cardiomyopathy (HCM) in Iceland. This cross-sectional observational study explored the penetrance and phenotypic burden among ...

(Iceland Glaciological Society and Geoscience Society of IcelandJöklarannsóknafélags Íslands og Jarðfræðafélags Íslands, 2008)Is Iceland a hotspot, with ridge-centered plume? In Iceland vigorous volcanism has built up a plateau 3.0 km higher than at a normal mid-ocean ridge with 3 to 4 times thicker crust than average oceanic crust. This volcanism can be associated with ...
-
(Springer Science and Business Media LLC, 2019-07-30)The extensive lava piles of Iceland contain a unique record of geomagnetic field variations spanning the past ~ 16 Ma. Since the 1950s, palaeomagnetic data have been obtained from over 9400 Icelandic lavas. We have compiled all palaeomagnetic data ...
-
(Elsevier, 2023-02-21)This study aimed to apply empirical data to assess wind energy production at the Búrfell site in Iceland based on the E44 turbine model. The empirical data are 5 years of recordings at the site location by the Iceland Metrological office. The wind speed ...

(Regional Euro-Asian Biological Invasions Centre Oy (REABIC), 2020-05-07)Non-indigenous species (NIS) represent a serious problem worldwide, where ascidians are one of the most important taxa. However, little has been done to document the non-indigenous ascidians in Iceland, and over the past decade only two species ...
-
(University of Iceland, 2017-01)At preschool, children are socially active--they engage in various social interactions with their peers and teachers. Social interactions require people to understand others’ minds (e.g., perspectives, ideas, emotional states, thoughts, intentions, ...
-
(The Educational Research Institute, 2020-06-23)The aim of this paper is to present and analyze how university students experience teaching methods of Icelandic as a second language and communication with teachers during the learning process. The theoretical framework includes multicultural education ...
