(Menntavísindastofnun, Menntavísindasvið, Háskóli Íslands, 2020-03-25)stærðfræðinámi er mikilvægt að huga að uppbyggingu hugtakaskilnings. Góð leið til þess er að rannsaka og prófa hugtök með áþreifanlegum verkefnum og tilraunum. Líkur er eitt af þeim hugtökum sem gott er að glöggva sig á með tilraunum. Líkum má skipta ... -
(Menntavísindasvið Háskóla Íslands, 2012-12-31)Á undanförnum áratugum hafa mannréttindi og jafn réttur allra hópa til þeirra gæða sem samfélagið hefur upp á að bjóða öðlast æ þýðingarmeiri sess. Samningur Sameinuðu þjóðanna um réttindi fatlaðs fólks er dæmi um þessa þróun. Fullorðið fólk með fötlun ...

(Háskóli Íslands, Menntavísindasvið, 2020-03-18)Margir kennarar og foreldrar eru færir í að tala við börn um erfiða hluti. Það sakar samt ekki að rifja upp nokkur atriði nú þegar við erum upptekin af Covid-19. Daglega heyra börn um veiruna, sjúkdóma og dauðsföll sem henni tengjast og sum í návígi. ...

(Menntavísindasvið Háskóla Íslands, 2016-12-31)Í þessari grein verður fjallað um þá spurningu hvers vegna offita er í síauknum mæli við- fang heilbrigðisstétta og hvort sú þróun sé til hagsbóta fyrir feitt fólk. Þótt Alþjóðaheilbrigðismálastofnunin hafi lýst því yfir að offita sé meðal alvarlegustu ...

(American Geophysical Union (AGU), 2019-12-03)The Central Asian Pamir Mountains (Pamirs) are a high-altitude region sensitive to climatic change, with only few paleoclimatic records available. To examine the glacial-interglacial hydrological changes in the region, we analyzed the geochemical ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2022-09)Sustainable urban drainage systems (SUDS) are increasingly implemented to mitigate flood risk and augment environmental quality and wellbeing in cities. Vegetated swales are one of the most common SUDS components, yet they are among the least studied ...

(Frontiers Media SA, 2020-04-30)Lake Myvatn, Iceland, is one of the most biologically productive lakes in the northern hemisphere, despite seasonal ice cover. Hydrothermal and groundwater springs make up the dominant source to this lake, and we investigate their Mg isotope ratio to ...

(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 ...

(Public Library of Science (PLoS), 2019-08-23)Background: The debate whether "asymptomatic hyperuricemia" should be treated is still ongoing. The objective of this cross-sectional study was to analyze whether hyperuricema in the elderly is associated with joint pain. Methods and findings: Participants ...

(Institutionen för historiska studier, Göteborgs universitet, 2011)Icelandic society was transformed during the 13th century. There was no kingdom in Iceland until 1262/1264, when the Norwegian kingship annexed the country. Along with the kingship a new political system, with new rules and ways to acquire power, ...
