  • Koistinen, Olli-Pekka (Aalto University School of Science, 2019)
    Chemical reactions and other transitions involving rearrangements of atoms can be studied theoretically by analyzing a potential energy surface defined in a high-dimensional space of atom coordinates. Local minimum points of the energy surface correspond ...
  • Rahpeyma, sahar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2018-11-23)
    A comprehensive site-effect investigation framework was developed and applied to earthquake strong-motion data collected on small-aperture urban arrays, the ICEARRAY I in Hveragerði in the South Iceland Seismic Zone and ICEARRAY II in Húsavík in the ...
  • Etter, Simon; Addor, Nans; Huss, Matthias; Finger, David C. (Elsevier BV, 2017-10)
    Study region The hydropower reservoir of Gigerwald is located in the alpine valley Calfeisental in eastern Switzerland. The lake is fed by runoff from rain, snow melt and ice melt from a few small glaciers, as well as by water collected in a ...
  • Khanin, Vasilii M.; Vrubel, Ivan I.; Polozkov, Roman G.; Shelykh, Ivan; Venevtsev, Ivan D.; Meijerink, Andries; Wieczorek, Herfried; Boerekamp, Jack; Spoor, Sandra; Rodnyi, Piotr A.; Ronda, Cees (American Chemical Society (ACS), 2019-02-18)
    Afterglow is an important phenomenon in luminescent materials and can be desired (e.g., persistent phosphors) or undesired (e.g., scintillators). Understanding and predicting afterglow is often based on analysis of thermally stimulated luminescence ...
  • Wirbel, Anna; Jarosch, Alexander H.; Nicholson, Lindsey (Copernicus GmbH, 2018-01-19)
    Glaciers with extensive surface debris cover respond differently to climate forcing than those without supraglacial debris. In order to include debris-covered glaciers in projections of glaciogenic runoff and sea level rise and to understand the ...
  • Ágústsson, Atli (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-04-24)
    Introduction: Adult individuals with disability and low motor function frequently have body deformations, such as scoliosis and windswept hips. Posture management is a component of physical management, which aims to prevent or reduce the development ...
  • Safarian, Sahar; Unnthorsson, Runar; Richter, Christiaan (Elsevier BV, 2019-05-13)
    Currently around 10% of all energy generated worldwide comes from biomass. Most of this 10% is biofuel energy from the fermentation of corn and sugarcane. Fermentation of corn competes with the global food supply, and fermentation of sugarcane drives ...
  • Liu, Bo; Koziel, Slawomir; Ali, Nazar (Oxford University Press (OUP), 2016-11-20)
    Efficiency improvement is of great significance for simulation-driven antenna design optimization methods based on evolutionary algorithms (EAs). The two main efficiency enhancement methods exploit data-driven surrogate models and/or multi-fidelity ...
  • Schmidt, Louise Steffensen; Langen, Peter; Adalgeirsdottir, Gudfinna; Pálsson, Finnur; Guðmundsson, Sverrir; Gunnarsson, Andri (MDPI AG, 2018-11-15)
    Several simulations of the surface climate and energy balance of Vatnajökull ice cap, Iceland, are used to estimate the glacier runoff for the period 1980–2015 and the sensitivity of runoff to the spring conditions (e.g., snow thickness). The simulations ...
  • Gopalan, Giridhar Raja (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-08)
    The purpose of this thesis is to develop spatio-temporal statistical models for glaciology, using the Bayesian hierarchical framework. Specifically, the process level is modeled as a time series of computer simulator outputs (i.e., from a numerical ...
