A framework for isogeometric-analysis-based optimization of wind turbine blade structures
(Journal article; Peer reviewed, 2018)Early‐stage wind turbine blade design usually relies heavily on low‐fidelity structural models; high‐fidelity, finite‐element‐based structural analyses are reserved for later design stages because of their complex workflows ... -
A framework for mixing-reaction closure with the Linear Eddy Model
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:53, Doctoral thesis, 2010)This thesis presents a novel framework for mixing-reaction closure build on the Linear Eddy Model by Kerstein (1991B). The development of the modeling concept has been motivated by the need for better predictive tools for ... -
A framework for modeling internal mass transfer in atmospheric freeze drying
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:106, Doctoral thesis, 2011)In modeling of atmospheric freeze drying (AFD), the modeling of the product is often confined to either one-dimensional models or multi-dimensional models of very basic geometries. Such models are not able to handle a ... -
A Framework for Modeling Linear Surface Waves on Shear Currents in Slowly Varying Waters
(Journal article; Peer reviewed, 2019)We present a theoretical and numerical framework—which we dub the direct integration method (DIM)—for simple, efficient, and accurate evaluation of surface wave models allowing presence of a current of arbitrary depth ... -
A Framework for Modelling of Vendor Managed Inventory
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:64, Doctoral thesis, 2008) -
A framework for production rescheduling in sociotechnical manufacturing environments
(Journal article; Peer reviewed, 2016)No plan survives contact with reality. Despite the rich research base regarding handling uncertainty in production planning and control systems, there is an intellectual gap between theory and practice with regard to ... -
A Framework for the Implementation of Takt Time in High-Variety, Low-Volume Manufacturing Environments
(Master thesis, 2019)Verdikjeder med høg produktvariasjon og lave produksjonsvolum (HVLV) blir stadig viktigare då HVLV-produsentar lagar spesialtilpassa produkt i mange variantar som i aukande grad blir etterspurde i marknaden. For å kunne ... -
A Framework for Thermodynamic Design of Stirling Engines
(Master thesis, 2014)Most commercialized Stirling machines operate at high temperature differentials and ratios, therefore less is known of machines that operate at low temperatures. This thesis aims to establish specific parameters for Stirling ... -
A Framing Link Based Tabu Search Algorithm for Large-Scale Multidepot Vehicle Routing Problems
(Journal article; Peer reviewed, 2014)A framing link (FL) based tabu search algorithm is proposed in this paper for a large-scale multidepot vehicle routing problem (LSMDVRP). Framing links are generated during continuous great optimization of current solutions ... -
A fully coupled method for numerical modeling and dynamic analysis of floating vertical axis wind turbines
(Journal article; Peer reviewed, 2017)Offshore wind energy is one of the most promising renewable energy resources and an increasing interest arises to develop floating vertical axis wind turbines (VAWTs), which have the potential to reduce the cost of energy. ... -
A general data model for socioeconomic metabolism and its implementation in an industrial ecology data commons prototype
(Journal article; Peer reviewed, 2019)Until this day, data in industrial ecology (IE) have been commonly seen as existing within the domain of particular methods or models, such as input–output, life cycle assessment, urban metabolism, or material flow analysis ... -
A generalized Critical Success Factor Process Model for Managing Offshore Development Projects in Norway
(Dr.ingeniøravhandling, 0809-103X; 2002:76, Doctoral thesis, 2002)Managing offshore development projects in Norway is no doubt a challenging task because such projects often involve large capital investments with risks under dynamic and complex environments. Project managers play a ... -
A Generic Framework For Development and Implementation of Condition-Based Maintenance (CBM): A Case Study At Equinor
(Master thesis, 2021)Energisektorene opplever store endringer og blir konfrontert med et økende antall komplekse utfordringer. Olje- og gassindustrien (O&G) som operer på den norske kontinentalsokkelen regnes som en av de viktigste i norsk ... -
A generic lifetime estimation model for Francis turbines
(Master thesis, 2022)Ettersom mer intermitterende energikilder kobles til strømnettet må Francisturbiner i økende grad tilby balanseringstjenester. Dette fører til at turbinene periodisk opererer i suboptimale konfigurasjoner. Siden Francisturbiner ... -
A Generic Modelling Approach for Heavy Lifting Marine Operation
(Master thesis, 2014)This thesis project introduced a generic modelling approach for heavy lifting marine operation based on 20-sim simulation and Matlab control. The model is a multi-body dynamic system which can be divided into vessel, crane, ... -
A Geochemical and Petrological Analysis of the Klemetsaunet Rhyodacite, Central Norwegian Caledonides; Unraveling the Rock's Origin, Mineral Alteration, and Deformation Patterns.
(Master thesis, 2023)Klemetsaunet ryodacitten er en av tre felsiske intrusjoner som ble dannet i oseansk skorpe for om lag 481 ± 5 millioner år siden. Studieområdet ligger i de nordlige delene av Bymarka-ofiolitten i Trondheim, Norge, og er ... -
A geochemical, mineralogical and geotechnical characterization of the low plastic, highly sensitive glaciomarine clay at Dragvoll, Norway

A GIS-based green supply chain model for assessing the effects of carbon price uncertainty on plastic recycling
(Journal article; Peer reviewed, 2019)Recycling plastic can abate the environmental pollution as well as CO2 emissions by saving the carbon-intensive feedstock input. The uncertain carbon price places significant effects on the establishment and operation of ... -
A global assessment of a floating bridges ability to withstand a ship collision
(Master thesis, 2016)It is planned to exchange the ferry connections along the western coast of Norway with fixed road connections. To be able to do this, new concepts for fjord crossings have to be used. One of these alternatives is a floating ... -
A Global Model for Marine Invasive Species Distribution via Plastic Debris
(Master thesis, 2023)Marine økosystemer trues av spredningen av fremmede arter gjennom konkurranse om ressurser, endring av habitat og overføring av sykdommer. Disse faktorene kan akselerere nedgangen til innfødte arter og forstyrre økosystemers ...
