    • An Empirical Study on the Impact of Cultural Types on Resources Integration Model 

      Solvang, Wei Deng; Zhan, Yan; Lu, Jiansha (Journal article; Peer reviewed; Tidsskriftartikkel, 2012)
      From the perspective of Resource-based Theory (RBT), organizational culture can be a source of sustained competitive advantage. And resources integration models, divided by property rights of resource, not firm boundary, as internal and external resources integration models, are presented as being specific in different cultural contexts. However, the litera- ture review shows the absences of an ...
    • Analysis and Optimization of Sandwich Panels. Final report. 

      Røsdal, Arild (Master thesis; Mastergradsoppgave, 2017-06-15)
      "The first part of this project, are general about sandwich structures. A sandwich construction, consist of two plate outsides (facings) glued to a core in the middle. Sandwiches are used in construction that must have a low weight, but a high stiffness. This indicated racing cars, aeroplane, ship shelters. To understand a sandwich construction, the basis, is to understand the sandwich beam. The are ...
    • Approaches to learning of linear algebra among engineering students 

      Rensaa, Ragnhild Johanne (Peer reviewed; Bokkapittel; Bok; Book; Chapter, 2017-02)
      The present paper investigates engineering students` own descriptions of what they mean by learning of linear algebra and how they know that they have learned something. I seek to extract keywords from engineering students` descriptions of learning of this discipline by drawing on grounded theory techniques and classifying the answers in conceptual and procedural approaches. By this, both detailed ...

    • Asymptotic Behaviour of Ground States for Mixtures of Ferromagnetic and Antiferromagnetic Interactions in a Dilute Regime 

      Braides, Andrea; Causin, Andrea; Piatnitski, Andrey; Solci, Margherita (Journal article; Peer reviewed, 2018-04-30)
      We consider randomly distributed mixtures of bonds of ferromagnetic and antiferromagnetic type in a two-dimensional square lattice with probability 1−p 1−p and p, respectively, according to an i.i.d. random variable. We study minimizers of the corresponding nearest-neighbour spin energy on large domains in Z 2 Z2 . We prove that there exists p 0 p0 such that for p≤ p 0 p≤p0 such ...
    • Asymptotics of a spectral-sieve problem 

      Amirat, Youcef; Bodart, Olivier; Chechkin, Gregory; Piatnitski, Andrey (Peer reviewed, 2015-11-18)
      In a bounded domain with a thin periodically punctured interface we study the limit behavior of the bottom of spectrum for a Steklov type spectral problem, the Steklov boundary condition being imposed on the perforation surface. For a certain range of parameters we construct the effective spectral problem and justify the convergence of eigenpairs.

    • Atmospheric ice monitoring system operation at Remote locations in cold region 

      Virk, Muhammad Shakeel; Rashid, Taimur; Mustafa, Mohamad Y (Journal article; Peer reviewed; Tidsskriftartikkel, 2013)
      The problems encountered in installation, maintenance and operations of equipment in the cold climate regions are far more complicated than others. The contributing factors and problems that can affect the system operation and performance should be identified, assessed and focused within well-defined parameters before its installation in cold climate regions. The harsh cold environment, could not ...

    • Atmospheric Icing Sensors - Capacitive Techniques 

      Mughal, Umair Najeeb; Virk, Muhammad Shakeel (Peer reviewed, 2013-01-22)
      The application of capacitive sensing technique is widely distributed in different physical domains primarily because of the diversity in dielectric permittivity and due to its minimum loading error and inertial effects. Atmospheric ice is a complex mixture of water, ice and air which is reflected in its complex dielectric constant. There are many existing atmospheric icing sensors but only few are ...
    • Atomized feedback, an approach to automatic formative assessment 

      Steen, Arild; Movik, Hans Richard (Peer reviewed; Chapter, 2017-11)
      In this article, we describe an approach to give automatic formative evaluation by atomizing the feedback. The mechanics in this approach is a large number of multiple-choice tests. The multiplechoice tests are used as voluntary assignments and gives controlled progression by releasing the tests in an order. Instruction is in the spirit of flipped classroom with short video lectures accompanied by ...
