Improving the Decision-making of Reverse Logistics Network Design Part I: A MILP Model under Stochastic Environment
(Peer reviewed; Bokkapittel; Book; Bok; Chapter, 2018-02-11)
The study of the network design problems related to reverse supply chain and reverse logistics is of great interest for both academicians and practitioners due to its important role for a sustainable society. However, reverse logistics network design is a complex decision-making problem that involves several interactive factors and faces many uncertainties. Thus, in order to improve the reverse ...
Large-Scale Additive Manufacturing Machine
(Master thesis; Mastergradsoppgave, 2018-08-21)
This master thesis contains an overview of the additive manufacturing technology and building process of the large-scale Fused Deposition Modelling (FDM) additive manufacturing machine from the old Wafer Handling Diffusion machine. The thesis study is mainly focused on practical work and describes the techniques used during the project execution. The built machine can print large 3D prototypes from ...
Measuring Thickness of Marine Ice Using IR Thermography
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-04)
<p>There are several challenges to operating in a cold climate. Marine icing is one of them, and its mitigation is vital for marine operations.</p>
<p>The presented work is a laboratory-scale setup to measure marine ice thickness. The developed methodology can be applied towards de-/anti-icing setups. The method described is based on measuring the average surface temperatures of the marine ice. ...
Sound waves in fluidized bed using CFD–DEM simulations
(Conference object; Konferansebidrag, 2018)
The seminar is about modelling sound waves in a fluidized bed using CFD–DEM numerical simulations. The presented case includes the application of appropriate initial and boundary conditions to reproduce bed phenomena and the effect of varying the bed height. The results of the simulations matched those from the literature. The pressure and particle velocity profiles obtained feature oscillatory ...
A Literature Review on Technologies in Future Small-scale Intelligent Manufacturing Systems
(Peer reviewed; Chapter; Bokkapittel, 2018-02-05)
Emergence of global markets forces businesses to become more flexible and adaptive to constantly changing demands and environments. In order to do so, enterprises turn towards application of newest technologies in manufacturing in order to make them intelligent. Since Small and Medium Enterprises play the central role in the domain of European manufacturing, the question arises – based on their ...
Large-scale Wind Power Integration in Northern Norway
(Master thesis; Mastergradsoppgave, 2018-08-16)
Norway has very high flexibility in energy production since hydropower covers about 95% of yearly energy demand. It is best to have a combination of wind and hydropower and hence it applies perfectly here in Norway. The performance of the wind farm can be significantly enhanced by employing full-capacity converters. The state-of-the-art literature study has been done on Squirrel Cage Induction ...
Effect of seasonal mesoscale and microscale meteorological conditions in Ny-Ålesund on results of monitoring of long-range transported pollution
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-06)
Ny-Ålesund is an international research settlement where the thermodynamics and chemical composition of the air are monitored. The present work investigates the effects of micrometeorological conditions, mesoscale dynamics and local air pollution on the data collected at two different locations around the village. Daily filter measurements of sulphur dioxide and non-sea salt sulphate from the temporary ...
Improving the Decision-making of Reverse Logistics Network Design Part II: An Improved Scenario-based Solution Method and Numerical Experimentation

A Trade-off Model for Green Supply Chain Design: An Efficiency-versus-Emission Analysis
(Peer reviewed; Chapter; Bokkapittel, 2018-04-09)
—With the growing concern of climate change and global warming, the reduction on carbon emissions of supply chain activities have been increasingly focused by both academics and corporates in the last two decades. The increased public awareness on sustainability and stricter environmental policies together enforce the companies to rethink their practices in supply chain design and operations in an ...
On geometric construction of some power means
(Journal article; Peer reviewed, 2018-11-27)
In the homogenization theory, there are many examples where the effective conductivities of composite structures are power means of the local conductivities. The main aim of this paper is to initiate research concerning geometric construction of some power means of three or more variables. We contribute by giving methods for the geometric construction of the harmonic mean $ P_{-1} $ and the arithmetic ...
