This study develops a new simulation model by ASPEN Plus for gasification integrated with water-gas shift reactors and product recovery unit for hydrogen production. Timber and wood waste (T&WW) as a lignocellulosic biomass was also considered as the ...

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. ...

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 ...

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 ...

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 ...

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 ...

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 ...

The news media around the world has experienced drastic changes in recent decades, and the Icelandic media is no exception. These changes originate in political, economic and not least technological developments. In this article we map key developments ...

Political scientists have developed three main interpretations of the Icelandic power structure – namely, traditional elitism, competitive elitism and professional pluralism. These can be seen to some extent as successive regimes, with traditional ...
