Experimental Validation of End-Effector Stabilization for Underwater Vehicle-Manipulator Systems in Subsea Operations
(Journal article, 2018)This paper considers the kinematic control approach for controlling an underwater vehicle-manipulator system. Three different kinematic control schemes have been applied, and the performance of each scheme is compared. The ... -
Experimental validation of pressure drop models during flow boiling of R134a – effect of flow acceleration and entrainment
(Journal article; Peer reviewed, 2018)A crucial step to assure proficient work of power and process apparatus is their proper design. A wide array of those devices operates within boiling or condensation of the working fluid to benefit from high heat transfer ... -
Experimental Verification of a Coordinated Path-Following Strategy for Underactuated Marine Vehicles
(Journal article; Peer reviewed, 2019)This work presents the results of an experimental verification of a coordinated path following strategy for underactuated marine vehicles. The coordinated path following strategy is presented, and is then experimentally ... -
Experimental Verification of a Voltage Droop Control for Grid Integration of Offshore Wind Farms Using Multi-terminal HVDC
(Journal article; Peer reviewed, 2014)This paper presents an experimental verification of a voltage droop control for a multi-terminal HVDC system for the grid integration of offshore wind farms. The laboratory setup is composed by four voltage-source converter ... -
Experimental Verification of CO2 Dissolution Rate Due to Diffusion Induced Convection
(Journal article; Peer reviewed, 2017)An experimental setup has been designed for measuring the dissolution rate of buoyant CO2 into the water phase below. Experiments were performed in a high-pressure cell, where the water phase was stabilized by a porous ... -
Experimental verification of control methods for series connected VSCs applied to a modular HVDC power train for offshore wind
(Master thesis, 2023)I denne avhandlingen har strømkontroll og spenningsbalanseringskontroll av serie koblede modulære spenningskildeomformere (VSC) blitt testet eksperimentelt og gjennom simuleringer. Forskingen gjort i sammenheng med denne ... -
Experimental Verification of Optimal Tripping Curve
(Master thesis, 2021)To dynamiske semianalytiske modeller ble foresl˚att av Hovda 2019 for ˚a minimere aksiale vibrasjoner involvert i en boreoperasjon. En for n˚ar borkronen er p˚a bunnen og en for n˚ar borkronen er over bunnen. Sistnevnte ... -
Experimental verification of the elastic response in a numeric model of a composite propeller blade with bend twist deformation
(Journal article; Peer reviewed, 2021) -
Experimental verification of underwater positioning system in aquaculture
(Chapter; Peer reviewed, 2017)This paper presents a filter for positioning of an underwater vehicle in exposed aquaculture environments. The input to the filter is time of flight measurements from acoustic transponders mounted at near the sea surface. ... -
Experimental weathering of microplastic under simulated environmental conditions - Method development and characterization of pristine, photodegraded and mechanically weathered microplastic
(Master thesis, 2018)The aim of this master thesis was to investigate the physico-chemical changes of microplastic (MP) weathered under simulated environmental conditions: floating on the ocean surface and in the intertidal zone. Polyethylene ... -
Experimental, numerical and analytical investigation of the effect of screens on sloshing

Experimental-Computational Approaches to Identify Synergistic Effects of Anti-Cancer Drugs
(Doctoral theses at NTNU;2019:384, Doctoral thesis, 2019)Drug combinations are hoped to improve treatment response to anti-cancer drugs by targeting the cancers vulnerabilities at diverse trajectories. With a large number of approved agents of chemotherapeutic and targeted ... -
Experimentation on Surge waves in Three Phase Pipe Flows
(Master thesis, 2020)Det er utført forsøk i flerfaselaboratoriet ved NTNU med enkeltbølger (“surge waves”) i olje-vann-luft strøm i rør. Studien er en oppfølging av et tidligere prosjektarbeid. Forsøkene ble utført ved så lave luftrater som ... -
Experimentation with inverted indexes for dynamic document collections
(Master thesis, 2007)This report aims to asses the efficiency of various inverted indexes when the indexed document collection is dynamic. To achieve this goal, we experiment with three different overall structures: Remerge, hierarchical indexes ... -
Experimenting a Digital Collaborative Platform for Supporting Social Innovation in Multiple Settings
