  • Safarian, Sahar; Unnthorsson, Runar; Richter, Christiaan (American Society of Mechanical Engineers, 2020-01-21)
    Wood and paper residues are usually processed as wastes, but they can also be used to produce electrical and thermal energy through processes of thermochemical conversion of gasification. This study proposes a new steady state simulation model for down ...

    Identification of primary cells, such as mesenchymal stromal cells, at the molecular level is vital for better understanding of their differentiation pathways. Surface-enhanced Raman scattering has a potential to become a non-invasive screening method ...
  • Hyytia, Esa; Righter, Rhonda; Bilenne, Olivier; Wu, Xiaohu (Elsevier BV, 2017-09)
    We study the M/D/1 queue when jobs have firm deadlines for waiting (or sojourn) time. If a deadline is not met, a job-specific deadline violation cost is incurred. We derive explicit value functions for this M/D/1 queue that enable the development of ...
  • Hvannberg, Ebba Thora (ACM Press, 2018)
    In many domains, applications have a lifetime of several years, and evolve with new technologies, changing requirements and user behavior. Simulators have been used for training for decades and have evolved in different directions. To learn how ...

    In order to decrease spreading of Coronavirus disease 2019 (COVID-19) over the world, the activity of many industries has declined, several flights were cancelled and so many people staying home that made drop in fuel consumption in road transport. ...
  • Spagnol, Simone; Hoffmann, Rebekka; Kristjansson, Arni; Avanzini, Federico (Acoustical Society of America (ASA), 2017-04)
    Stimulus order has been reported to affect perceived loudness. This letter investigates how temporal order affects distance discrimination of receding and approaching pairs of sound sources rendered binaurally in the anechoic near-field. Individual ...
  • Samuelsson, Sigurdur Gauti; Book, Matthias (Association for Computing Machinery (ACM), 2020-11-04)
    Software engineers routinely use sketches (informal, ad-hoc drawings) to visualize and communicate complex ideas for colleagues or themselves. We hypothesize that sketching could also be used as a novel interaction modality in integrated software ...

    In this work we compute high-coverage hydrogen adsorption energies and geometries on the stepped platinum surfaces Pt(211) and Pt(533) which contain a (100)-step type and the Pt(221) and Pt(553) surface with a (111) step edge. We discuss these results ...
  • Fleps, Ingmar; Bahaloo, Hassan; Zysset, Philippe K.; Ferguson, Stephen J.; Pálsson, Halldór; Helgason, Benedikt (Elsevier BV, 2020-10)
    Introduction: Ultimate strength-density relationships for bone have been reported with widely varying results. Reliable bone strength predictions are crucial for many applications that aim to assess bone failure. Bone density and bone morphology have ...
  • Memon, Shahbaz; Riedel, Morris; Memon, Riedel,; Koeritz, Chris; Grimshaw, Andrew; Neukirchen, Helmut (West University of Timisoara, 2016-05-01)
    Emerging challenges for scientific communities are to efficiently process big data obtained by experimentation and computational simulations. Supercomputing architectures are available to support scalable and high performant processing environment, ...
  • Kristjánsdóttir, Þórdís; Ron, Emanuel Y.C.; Molins-Delgado, Daniel; Fridjonsson, Olafur; Turner, Charlotta; Björnsdóttir, Snædís; Guðmundsson, Steinn; van Niel, Ed W.J.; Karlsson, Eva Nordberg; Hreggvidsson, Gudmundur Oli (Elsevier BV, 2020-12)
    Rhodothermus marinus has the potential to be well suited for biorefineries, as an aerobic thermophile that produces thermostable enzymes and is able to utilize polysaccharides from different 2nd and 3rd generation biomass. The bacterium produces valuable ...
  • Book, Matthias; Riedel, Morris; Neukirchen, Helmut; Götz, Markus (ACM Press, 2017-10)
    The design, development and deployment of scientific computing applications can be quite complex as they require scientific, High-Performance Computing (HPC), and software engineering expertise. Often, HPC applications are however developed by end users ...
  • Memon, Ahmed Shiraz (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2021-06)
    Distributed data and compute infrastructures aim to provide access to their data or compute services across disciplinary and geographical borders to their users for scientific research. The services are highly collaborative in nature yet independent ...
  • Safarian, Sahar; Ebrahimi Saryazdi, Seyed Mohammad; Unnthorsson, Runar; Richter, Christiaan (MDPI, 2021-04-11)
    Wood and forestry residues are usually processed as wastes, but they can be recovered to produce electrical and thermal energy through processes of thermochemical conversion of gasification. This study proposes an equilibrium simulation model developed ...
