    In the recent years, formal modeling and verification of realtime systems have become very important. Difficult-to-use modeling languages and inefficient analysis tools are the main obstacles to use formal methods in this domain. Timed actor model is ...
  • Bean, Christian (2018-06)
    New automatic methods for enumerating permutation classes are introduced. The first is Struct, which is an algorithm that conjectures a structural description using rules similar to generalized grid classes. These conjectured structural descriptions ...
  • Sich, Maksym; Tapia-Rodriguez, Lucy E.; Sigurdsson, Helgi; Walker, Paul M.; Clarke, Edmund; Shelykh, Ivan; Royall, Benjamin; Sedov, Evgeny S.; Kavokin, Alexey V.; Skryabin, Dmitry V.; Skolnick, Maurice S.; Krizhanovskii, Dmitry N. (American Chemical Society (ACS), 2018-11-12)
    We report stable orthogonally polarized domains in high-density polariton solitons propagating in a semiconductor microcavity wire. This effect arises from spin-dependent polariton–polariton interactions and pump-induced imbalance of polariton spin ...

    Superheated steam from high enthalpy vapor dominated geothermal fields offers an opportunity to extract greater exergy per unit flow with higher thermodynamic output efficiency compared to conventional geothermal wells. The first full scale well drilled ...
  • Eyþórsson, Elías (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-06-05)
    Streptococcus pneumoniae is a Gram-positive diplococcus that is both a commensal bacterium in the upper respiratory tract of humans, and a common pathogen. The infectious manifestations of pneumococci span a range from benign to serious; from acute ...
  • Ali, Jafari (2016-06)
    This dissertation is composed of two parts. In the first part, performance evaluation and verification of safety properties are provided for real-time actors. Recently, the actor-based language, Timed Rebeca, was introduced to model distributed and ...
  • Lejsek, Herwig (2015-06)
    This thesis presents the NV-tree (Nearest Vector tree), which addresses thespecific problem of efficiently and effectively finding the approximatek-nearest neighbors within large collections of high-dimensional data points.The NV-tree is a very ...
  • Mixa, Már Wolfgang (2016-06)
    The research project focuses on investment behavior and the Icelandic economic bubble and crash, emphasizing that investment behavior has to be seen within a historical and cultural environment. As such the project is related to financial history and ...
  • Costa, Maria (University of Iceland, School of Health Sciences, Faculty of Pharmaceutical Sciences, 2019-06)
    In the course of a nearly century-long global effort to discover new bacterialderived drugs from the environment, there have been few innovations to the way that researchers have collected samples and subsequently created microbial libraries sourced ...
  • Bjarnason, Thorarinn Arni (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-06)
    Sykursýki 2 (SS2) og forstig SS2 eru þekktir áhættuþættir æðakölkunar og alvarlegra fylgikvilla hjarta- og æðasjúkdóma. Skimun sjúklinga með brátt kransæðaheilkenni (BKH) með sykurþolsprófi hefur gefið til kynna hátt algengi ógreindrar SS2 og forstigs ...
  • Scully, Sean (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05-31)
    The protein and amino acid metabolism of thermophilic bacteria has been a neglected aspect of their physiology despite its biotechnological potential. Under anaerobic conditions, the metabolism of many proteogenic amino acids requires the presence of ...

    Bone area is one measure of bone size that is easily derived from dual-energy X-ray absorptiometry (DXA) scans. In a GWA study of DXA bone area of the hip and lumbar spine (N ≥ 28,954), we find thirteen independent association signals at twelve loci ...
