Isogeometric analysis using a tensor product blending spline construction
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-01)In this paper, we introduce a blending spline type construction into the isogeometric analysis. We consider a general algorithm for solving a number of boundary value problems, including heat equation, wave equation, linear elasticity, etc. The usage of blending spline construction in the isogeometric context mixes standard finite element and NURBS-based approaches while accumulating the benefits ... -
Experiments on turbulence from colliding ice floes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-16)Increased knowledge about energy dissipation processes around colliding ice floes is important for improved understanding of atmosphere-ice-ocean energy transfer, wave propagation through sea ice, and the polar climates. The aim of this study is to obtain such information by investigating colliding ice floe dynamics in a large-scale experiment and directly measuring and quantifying the turbulent ... -

This study contributes to the literature by developing computationally ... -
Review on material and design of anode for microbial fuel cell
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-21)Microbial Fuel Cell (MFC) is a bio-electrochemical system that generates electricity by anaerobic oxidation of substrates. An anode is the most critical component because the primary conversion of wastewater into electrons and protons takes place on the surface of the anode, where a biofilm is formed. This paper describes the essential properties of the anode and classifies its types according ... -
Using Deep Learning to Predict the Amount of Chemicals Applied on the Wheel Track for Winter Road Maintenance
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-30)The decade of big data has emerged in recent years, which has led to entering the era of intelligent transportation. One of the main challenges to deploying intelligent transportation is dealing with winter roads in cold climate countries. Different operations can be used to protect the road from ice and snow, such as spreading chemicals (here salt) on the road surface. Using salt for de-icing and ... -
Variable Neighborhood-based Cuckoo Search for Production Routing with Time Window and Setup Times
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-23)Major corporations compete over the strengths of their supply chains. Integrating production and distribution operations helps improve supply chain connectedness and responsiveness beyond the standalone optimization norms. This study proposes an original Mixed-Integer Linear Programming (MILP) formulation for the Production scheduling-based Routing Problem with Time Window and Setup Times (PRP-TWST). ... -
Towards the smart and sustainable transformation of Reverse Logistics 4.0: a conceptualization and research agenda
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)The recent advancement of digitalization and information and communication technology (ICT) has not only shifted the manufacturing paradigm towards the Fourth Industrial Revolution, namely Industry 4.0, but also provided opportunities for a smart logistics transformation. Despite studies have focused on improving the smartness, connectivity, and autonomy of isolated logistics operations with a primary ... -
Analysis of local climate effects for Martineåsen development project in Larvik
(Master thesis; Mastergradsoppgave, 2017-08-15)The goal of this thesis is to perform analysis of local climate effects for Martineåsen development project in Larvik. The Norwegian regulatory acts place a strict requirements on outdoor areas comfort criteria and thus for the purpose of said development project, strict adherence to these acts is necessary. The outdoor comfort in cold climate is mostly governed by wind, and thus study of local ... -
Statistical Optimization of Pyrolysis Process for Thermal Destruction of Plastic Waste Based on Temperature-Dependent Activation Energies and Pre-Exponential Factors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-09)The massive increase in disposable plastic globally can be addressed through effective recovery methods, and one of these methods is pyrolysis. R software may be used to statistically model the composition and yield of pyrolysis products, such as oil, gas, and waxes to deduce an effective pyrolysis mechanism. To date, no research reports have been documented employing the Arrhenius equation in R ... -
Experimental Study of Power Generation and COD Removal Efficiency by Air Cathode Microbial Fuel Cell Using Shewanella baltica 20
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-05)Microbial fuel cells (MFCs) are a kind of bioreactor for generating electricity, facilitated by exoelectrogens while treating wastewater. The present article focuses on the performance of an air cathode plexiglass MFC in terms of chemical oxygen demand (COD) removal efficiency and power output by performing two sets of experiments. The proton exchange membrane and electrode materials were Nafion ... -

Computational Fluid Dynamics - A Stepping-Stone of MULTIPHYSICS
(Conference object; Konferansebidrag, 2022-07-07)Fluids have been around us for as long as we know; they have enabled us to cross the oceans, ride the winds, shorten distances, and much more. Computational Fluid Dynamics (CFD) has extended our understanding of fluids. Even to this day, the analytical solution of fundamental equations of fluid mechanics remains a million-dollar award problem (Clay Mathematics Institute). As engineers, we’ll leave ... -

Weighted Boundedness of Certain Sublinear Operators in Generalized Morrey Spaces on Quasi-Metric Measure Spaces Under the Growth Condition
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-17)We prove weighted boundedness of Calderón–Zygmund and maximal singular operators in generalized Morrey spaces on quasi-metric measure spaces, in general non-homogeneous, only under the growth condition on the measure, for a certain class of weights. Weights and characteristic of the spaces are independent of each other. Weighted boundedness of the maximal operator is also proved in the case when ... -
