A Model Library for Oil/Water Emulsion Separation and Transport Processes
(Doctoral thesis, 2023)In the petroleum industry, the separation and transportation of multiphase fluids, especially crude-oil and water emulsions, hold immense economic and environmental significance. Thus, development of fundamentally advanced, ... -
Model molecules mimicking asphaltenes
(Journal article; Peer reviewed, 2015)Asphalthenes are typically defined as the fraction of petroleum insoluble in n-alkanes (typically heptane, but also hexane or pentane) but soluble in toluene. This fraction causes problems of emulsion formation and ... -
A model of factors influencing deck officers' cyber risk perception in offshore operations
(Journal article; Peer reviewed, 2022)Offshore operations onboard vessels are increasingly reliant on digitalization, integration, automation, and networked-based systems, which creates new dimensions of cyber risks. The causes of cyber incidents often include ... -
Model of Hook Load During Tripping Operation
(Master thesis, 2013)Drilling after oil and gas becomes more challenging for every drilled well; deeper, longer, harder, higher temperature, higher pressure and more complex conditions. The equipment requirements and well integrity regulations ... -
A model of intervention and implementation of quality building and quality control in childcare centers to strengthen the mental health and development of 1-3-year olds: Protocol for a randomized controlled trial of thrive by three
(Peer reviewed; Journal article, 2020)Background: Universal, high-quality childcare offers a unique opportunity to prevent developmental trajectories leading to mental health problems. Yet, growing evidence has shown that the process quality of Norwegian ... -
Model of Single-Phase Synchronous Generator for Rotary Frequency Converter
(Master thesis, 2018)Synchronous-synchronous rotary frequency converters are in the Norwegian traction power system applied for converting three-phase AC voltage at 50 Hz to single-phase AC voltage at 16 2/3 Hz. The converters consist of a ... -
Model of single-phase synchronous machine for rotary frequency converter - Developement of time-domain model, including excitation system
(Master thesis, 2016)This thesis concerns the development of a single-phase synchronous machine model in time-domain, with instantaneous value output. The model is meant to represent the generator part of the rotary converter used in the ... -
A Model of Synovial Fluid with a Hyaluronic Acid Source: A Numerical Challenge
(Journal article; Peer reviewed, 2021) -
A model of the interrelationship between research ethics and research integrity
(Peer reviewed; Journal article, 2024)Purpose: The purpose of this article is to explore the interrelationship between research ethics and research integrity with a focus on the primary forms of research misconduct, including plagiarism, fabrication, and ... -
Model orbit output feedback tracking of underactuated mechanical systems with actuator dynamics
(Journal article; Peer reviewed, 2019)Robust periodic motion generation is developed for a class of mechanical systems with actuator dynamics. The virtual constraint (VC) approach is first refined under incomplete state measurements and it is then extended to ... -
Model Order Reduction Technique Applied on Harmonic Analysis of a Submerged Vibrating Blade
(Journal article; Peer reviewed, 2019)As part of an ongoing study into hydropower runner failure, a submerged, vibrating blade is investigated both experimentally and numerically. The numerical simulations performed are fully coupled acoustic-structural ... -
Model Predictive Control Allocation
(Master thesis, 2011)This thesis developes a control allocation method based on the Model Predictive Control algorithm, to be used on a missile in flight. The resulting Model Predictive Control Allocation (MPCA) method is able to account for ... -
Model Predictive Control based on Sliding Mode Control
(Doctoral theses at NTNU;2019:333, Doctoral thesis, 2019)Design of a controller that is capable to control the process in order to obtain desired overall system performance is a standard problem in all industries. Use of computers and microprocessors have resulted in increased ... -
Model Predictive Control for a De-oiling Hydrocyclone: A Theoretical and Experimental Study
(Master thesis, 2021)Utslipp av produsert vann er en voksende bekymring på grunn av den negative miljøpåvirkningen. En potensiell løsning er de-oiling hydrosykloner, som er den mest brukte teknologien for å rense produsert vann. Compact Separator ... -
Model predictive control for a multi-body slung-load system
