    • A critical discussion of the subduction-collision model for the Neoproterozoic Araçuaí-West Congo orogen 

      Fossen, Haakon; Cavalcante, Carolina; Konopásek, Jiří; Meira, Vinicius T.; Paes de Almeida, Renato; Hollanda, Maria Helena BM de; Trompette, Roland (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-22)
      The Neoproterozoic Araçuaí-West Congo orogen in Brazil and Congo represents a branch of the Brasiliano/Pan-African orogenic system that is considered to terminate northward into a confined cratonic environment defined by the horseshoe-shaped pre-Atlantic São Francisco-Congo craton. The prevailing interpretation is that this orogen formed as a result of 50 m.y. of subduction leading to a classical ...
    • Onshore and Offshore Coordination of Logistics Services at Seaports 

      Adu-Gyamfi Appiah, Bright (Master thesis; Mastergradsoppgave, 2019-06-28)
      As global trade increases, sizes of vessels and cargo throughputs have also experienced a sudden rise thereby putting excess pressure on ship berths and ports. This is shifting most ports to much smarter technological solutions with the aim of optimizing operations, increasing efficiency and reducing logistics cost without the need for huge infrastructural and equipment investments. Developing the ...

    • Production and Logistics Systems Improvements - Biim Ultrasound AS 

      Tofah, Dzifa Korbla Wisdom (Master thesis; Mastergradsoppgave, 2019-06-28)
      A crucial aspect of the supply chain network design process is deciding on optimal locations to situate new facilities. Facility location decisions rely on many factors, some of which might be conflicting with each other. The decision factors can be either quantitative or qualitative, thus a brute-force prioritization of one over another could be detrimental overall. To ensure the efficacy of the ...

      Arnarson, Halldor (Master thesis; Mastergradsoppgave, 2019-06-28)
      A digital twin is a new and emerging tool of the fourth industrial revolution. It is an extensive part of connecting the manufacturing equipment together to develop a smart factory. Investigation of simulating manufacturing system to bind the digital world with the physical, allows for analysis of data and monitoring of systems to head off problems before they even occur, preventing downtime, develop ...
    • Thin Wall Structure by Welding 

      Arumairasa, Hans Ivar (Master thesis; Mastergradsoppgave, 2019-06-28)
      Manufacturing of thin wall structure by wire arc additive manufacturing (WAAM) is on the main application of additive manufacturing. 3D-printing technology has significant advantages over traditional milling and machining techniques or welded analogs. Thin wall structure constitutes an essential and growing proportion of engineering construction, within common areas as in structural aerospace and ...
    • Optimized cardiac simulation as a tool to understand patient specific mechanical function 

      Odeigah, Oscar Ofordile (Master thesis; Mastergradsoppgave, 2019-06-28)
      The muscular tissue of the heart is able to contract in the absence of external load. This behaviour is stimulated by a spontaneous electrical depolarization of cardiac cells in the sinoatrial node, which spreads electrical activation through the whole heart, that triggers the synchronized mechanical contraction of the heart muscle. This phenomenon, referred to as active contraction is commonly ...
    • Wind turbine and ice breaking 

      Nilsen, Peter Tor Furseth (Master thesis; Mastergradsoppgave, 2019-06-28)
      The arctic climate imposes the challenge of ice accretion on the blades of the wind turbine created by the atmospheric ice. Over time, the ice build-up causes ice shedding which can do structural damage to the wind turbine. The process involving ice breaking and shedding is not well understood. This document explains the mechanical properties of ice such as density, coefficient of thermal expansion, ...

    • Low proficiency does not mean ab initio: A methodological footnote for linguistic transfer studies 

      Puig-Mayenco, Eloi; Rothman, Jason (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-17)
      The goal of this brief article is to highlight a specific methodological consideration pertaining to the examination of linguistic transfer in sequential language acquisition: When and how can transfer be meaningfully disentangled from issues pertaining to developmental trajectories of the target language? While this methodological issue is relevant for all transfer studies irrespective of learner ...
    • Is Logic Distinctively Normative? 

      Labukt, Ivar Russøy (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-01)
      Logic is widely held to be a normative discipline. Various claims have been offered in support of this view, but they all revolve around the idea that logic is concerned with how one ought to reason. I argue that most of these claims—while perhaps correct—only entail that logic is normative in a way that many, if not all, intellectual disciplines are normative. I also identify some claims whose ...
    • Interventionary order and its methodologies: the relationship between peace and intervention 

      Richmond, Oliver (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-19)
      Recently there have been calls from policymakers around the world for practically engaged research to produce evidence-based policy for peace, security and development. Policymakers aim to align three types of methodological approaches to knowledge about peace, security and development in international order: methodological liberalism at state and international levels, aligned with ‘methodological ...

      Steinhauer, Peer Salvator (Master thesis; Mastergradsoppgave, 2019-06-28)
      A small and medium sized enterprise (SME) with an assembly to order manufacturing system (ATO-MS) depending on a global supply chain has especially challenges when it comes to secure the quality. The parts procured from a global supply chain represent a big amount of value invested in to the short line of the MS. Depending on the definition of quality from the suppliers, how can the company react ...
    • Duration and extent of bilingual experience modulate neurocognitive outcomes 

      Deluca, Vincent; Rothman, Jason; Bialystok, Ellen; Pliatsikas, Christos (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-24)
      The potential effects of bilingualism on executive control (EC) have been heavily debated. One possible source of discrepancy in the evidence may be that bilingualism tends to be treated as a monolithic category distinct from monolingualism. We address this possibility by examining the effects of different bilingual language experiences on brain activity related to EC performance. Participants were ...
