(IEEE, 2014)Hyperspectral remote sensing technology allows one to acquire a sequence of possibly hundreds of contiguous spectral images from ultraviolet to infrared. Conventional spectral classifiers treat hyperspectral images as a list of spectral measurements ... -
(IEEE, 2014)Hyperspectral remote sensing images contain hundreds of data channels. Due to the high dimensionality of the hyperspectral data, it is difficult to design accurate and efficient image segmentation algorithms for such imagery. In this paper, a new ...
-
(IEEE, 2015-05)A novel feature selection approach is proposed to address the curse of dimensionality and reduce the redundancy of hyperspectral data. The proposed approach is based on a new binary optimization method inspired by fractional-order Darwinian particle ...
-
(IEEE, 2014)A new spectral-spatial method for classification of hyperspectral images is introduced. The proposed approach is based on two segmentation methods, fractional-order Darwinian particle swarm optimization and mean shift segmentation. The output of these ...
-
(Multidisciplinary Digital Publishing Institute, 2016)This paper introduces a new supervised classification method for hyperspectral images that combines spectral and spatial information. A support vector machine (SVM) classifier, integrated with a subspace projection method to address the problems of ...

(The European Association of Distance Teaching Universities (EADTU), 2016-06)An overview is given of experiences of MOOCs in Iceland. An open online Icelandic language course from 2004 at the University of Iceland (UI) has been popular and remains open. A work group, formed in 2013 by the president of the UI, analysed the MOOC ...

(Félagsfræðingafélag Íslands, 2014)Í kjölfar hruns íslensku bankanna árið 2008 urðu töluverðar breytingar á íslensku samfélagi. Tekjudreifing breyttist þegar kaupmáttur lækkaði mikið í kjölfar falls krónunnar. Á sama tíma minnkaði ójöfnuður m.a. vegna samþjöppunar í efri hluta ...

(Institute of Public Administration and Politics Stofnun stjórnsýslufræða og stjórnmála, 2013)In Mars 2013 the Icelandic Parliament decided upon the first formal “Icelandic Cultural Policy”. In this article that document is examined in light of debates concerning the concept of deliberate cultural policy making. Two main themes stand out as ...
-
(ELSEVIER SCIENCE BV, 2015-11-01)Every year, numerous studies are published that compare the effects of different factors on the growth of aquaculture fish. However, comparatively little attention has been given to the experimental designs of these studies - in how many rearing units ...
-
(Agricultural University of Iceland and other Research Institutions in Iceland, 2015)Ethanol production using Paenibacillus strain J2 was studied on carbohydrates and lignocellulosic biomass hydrolysates including grass (Phleum pratense) and barley straw (Hordeum vulgare). The strain has a broad substrate spectrum; fermentation of ...
-
(Hindawi Publishing Corporation, 2012)Thermophilic bacteria have gained increased attention as candidates for bioethanol production from lignocellulosic biomass. This study investigated ethanol production by Thermoanaerobacter strain J1 from hydrolysates made from lignocellulosic biomass ...
-
(IIT Bombay Publications, 2015-12)In the aftermath of the financial crisis that invested Iceland starting in September 2008 the town of Hveragerði decided to launch at the end of 2008 a national competition to gather ideas on how a more sustainable future could be designed and implemented ...
-
(2016-03-19)The Icesave dispute Iceland fought with the UK and Dutch governments reviled inhered weakness of the European financial system. Bringing forward tension of legal division between public and private law and falling outside framework of traditional neatly ...
-
(University of Iceland, 2015)Though nationalism has always been strong in Iceland, populist political parties did not emerge as a viable force until after the financial crisis of 2008. On wave of the crisis a completely renewed leadership took over the country’s old agrarian party, ...
-
(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 ...
-
(International Society for Aeolian Research, 2016-02-15)Iceland has the largest area of volcaniclastic sandy desert on Earth or 22,000 km2. The sand has been mostly produced by glacio-fluvial processes, leaving behind fine-grained unstable sediments which are later re-distributed by repeated aeolian events. ...
-
(Society of Wetland Scientists, 2016-06-09)Iceland has inland wetland areas with soils exhibiting both Andosol and Histosol properties which are uncommon elsewhere on Earth. They are generally fertile, with higher bird-nest densities than in similar wetlands in the neighboring countries, with ...
-
(Stofnun stjórnsýslufræða og stjórnmála við Háskóla Íslands, 2015)This paper argues that Iceland enjoyed essential shelter, for its development and prosperity, provided by Denmark and Britain. Societal relations with Copenhagen were of fundamental importance in the preservation and evolution of Icelandic identity and ...

(Stofnun stjórnsýslufræða og stjórnmála við Háskóla Íslands, 2015)Þessi rannsókn snýst um hugmyndir og hagsmuni í heilbrigðisþjónustu á Íslandi. Rannsóknin lýsir því hvernig annars vegar hugmyndin um heilsugæsluna sem fyrsta viðkomustað sjúklinga í heilbrigðiskerfinu og hugmyndin um það að sjúklingar eigi að hafa ...

(IEEE, 2015)Just over a decade has passed since the concept of morphological profile was defined for the analysis of remote sensing images. Since then, the morphological profile has largely proved to be a powerful tool able to model spatial information (e.g., ...
