    Røhne, Mette; Boysen, Elin Sundby; Ausen, Dag (Journal article; Peer reviewed, 2017)
    The study explores how mobile safety alarms can be utilized for ambient assisted living (AAL), and provides elderly safety, autonomy, independence and mobility. The aim is to generate knowledge on usage, usability and ...
  • Online monitoring of aluminium primary production gas composition by use of Fourier-transform infrared spectroscopy 

    Aarhaug, Thor Anders; Ferber, Alain Marc C; Kjos, Ole Sigmund; Gaertner, Heiko (Journal article; Peer reviewed, 2014)
    Online monitoring of aluminium primary production raw gas is challenging due to the high concentration of HF in the presence of water. Tunable Diode Laser (TDL) analyzers retrofitted with sapphire optical windows allow for ...
  • Stability Analysis of a Hierarchical Architecture for Discrete-Time Sensor-based Control of Robotic Systems 

    Bjerkeng, Magnus Christian; Falco, Pietro; Natale, Ciro; Pettersen, Kristin Ytterstad (Journal article; Peer reviewed, 2014)
    The stability of discrete time kinematic sensor-based control of robots is investigated in this paper. A hierarchical inner-loop/outer-loop control architecture common for a generic robotic system is considered. The inner ...
  • Comprehending Feature Models Expressed in CVL 

    Reinhartz-Berger, Iris; Figl, Kathrin; Haugen, Øystein (Journal article; Peer reviewed, 2014)
    Feature modeling is a common way to present and manage variability of software and systems. As a prerequisite for effective variability management is comprehensible representation, the main aim of this paper is to investigate ...
  • BVR - Better Variability Results 

    Haugen, Øystein; Øgård, Ommund (Journal article; Peer reviewed, 2014)
    We present BVR (Base Variability Resolution models), a language developed to fulfill the industrial needs in the safety domain for variability modeling. We show how the industrial needs are in fact quite general and that ...
  • Similarity detection of rational space curves 

    Alcazar, Juan Gerardo; Hermoso, Carlos; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2017)
    We provide an algorithm to check whether two rational space curves are related by a similarity. The algorithm exploits the relationship between the curvatures and torsions of two similar curves, which is formulated in a ...
  • Symbols and exact regularity of symmetric pseudo-splines of any arity 

    Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2017)
    Pseudo-splines form a family of subdivision schemes that provide a natural blend between interpolating schemes and approximating schemes, including the Dubuc–Deslauriers schemes and B-spline schemes. Using a generating ...
  • Symmetries of canal surfaces and Dupin cyclides 

    Alcazar, Juan Gerardo; Dahl, Heidi Elisabeth Iuell; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2017)
    We develop a characterization for the existence of symmetries of canal surfaces defined by a rational spine curve and rational radius function. In turn, this characterization inspires an algorithm for computing the symmetries ...
