Polynomial Chaos Expansion for Uncertainty Quantification in Closed-Loop Reservoir Management
(Chapter, 2023)Closed-loop reservoir management (CLRM) is a model-based optimal control procedure that aims at optimizing oil and gas production strategies under both physical and operational constraints and large model uncertainties. ... -
Shipping Safety in the Arctic - Contributions to the understanding of shipping risk during escort and convoy operations
(Doctoral theses at NTNU;2024:200, Doctoral thesis, 2024)The decline in Arctic ice extent has drawn increasing attention to Arctic shipping. In comparison to traditional routes, Arctic routes offer substantial advantages, particularly in terms of time efficiency and cost ... -
Modelling Biodiversity Impacts of future Energy Systems in Norway
(Doctoral theses at NTNU;2024:201, Doctoral thesis, 2024)Global renewable energy production must triple by 2030 to mitigate global warming. This requires a considerable expansion of global energy facilities and electric grids. Norway is well-positioned for this energy transition, ... -
Mixed-methods approach to studying multiuser perceptions of an interim Complete Streets project in Norway
(Journal article; Peer reviewed, 2022)Research on multiuser perceptions of street environment alterations has been gathering attention in recent years given an increased focus on both sustainable city development and public participation. This study investigated ... -
Suitability of seawater for mixing and curing of cementitious materials: a step towards sustainability
(Journal article; Peer reviewed, 2023) -
Demonstrating the load-shifting potential of a schedule-based control in a real-life educational building
(Journal article; Peer reviewed, 2024)This work investigates the potential of simplified control approaches to deploy the building energy flexibility (BEF), here for the shifting of the space-heating load in a real-life educational building. The educational ... -
Assessment of long-term performance of natural fibre reinforced polymer composites with recyclable polymer matrices under different environmental ageing conditions
(Doctoral theses at NTNU;2024:167, Doctoral thesis, 2024)The usage of natural fibre composites (NFCs) has been increasing recently to replace traditional composite materials in different sectors due to climate change and sustainability issues. However, natural fibres are ... -
Joint well-placement and well-control optimization for energy-efficient water flooding of oil fields
(Journal article; Peer reviewed, 2023)Hydrocarbon production driven by water flooding is energy-intensive. This paper presents well-placement and joint well-placement-and-control optimization studies with objective function taking into account emissions, ... -
A Novel Method for Anomaly Detection and Signal Calibration in Water Quality Monitoring of an Urban Water Supply System
(Journal article; Peer reviewed, 2024)Water quality monitoring plays a crucial role in urban water supply systems for the production of safe drinking water. However, the traditional approach to water monitoring in Norway relies on a periodic (weekly/biweekly/monthly) ... -
Volumetric visualization of vanishing vortices in wind turbine wakes
(Journal article; Peer reviewed, 2024)Volumetric velocimetry is used to investigate the evolution of tip vortices in the wake of a model wind turbine. The power spectral density of streamwise velocity fluctuations is estimated at several downstream locations, ... -
Critical Concerns of Deploying Blockchain in Internet of Things Applications
(Journal article; Peer reviewed, 2024)The Internet of Things (IoT) and blockchain are both recognized as cutting-edge, popular technologies. In contrast to IoT, which pertains to the spread of linked equipment via supplying information over the Internet, ... -
Climate and Environmental Monitoring using GNSS Remote Sensing
(Doctoral theses at NTNU;2024:209, Doctoral thesis, 2024)The potential of Global Navigation Satellite System (GNSS) signals for remote sensing applications has been widely recognized. The widespread availability of GNSS signals, whether in direct form or as reflections, enables ... -
Thermodynamic analysis of rotary pressure exchanger and ejectors for CO2 refrigeration system
(Journal article; Peer reviewed, 2024)Natural refrigerant CO2 has become a viable choice for refrigeration units for land-based and offshore applications due to its environment-friendly nature and compactness. The CO2 transcritical cycle allows operating in ... -
A novel framework for assessing the smartness and the smart readiness level in highly electrified non-residential buildings: A Norwegian case study
(Journal article; Peer reviewed, 2024)This work presents a new operational framework to measure the smartness and smart readiness of highly electrified buildings. The framework seeks to enhance legacy systems and controls of existing buildings and establish ... -
Experimental and numerical investigations of the water surface profile and wave extrema of supercritical flows in a narrow channel bend
(Journal article; Peer reviewed, 2024)Supercritical flows in channel bends, e.g., in steep streams, chute spillways, and flood and sediment bypass tunnels (SBTs), experience cross-waves, which undulate the free surface. The designs of these hydraulic structures ... -
Do nothing, do minimum or do something? Why public project appraisals “always” recommend large projects
(Journal article; Peer reviewed, 2024)Purpose: In the project initiation phase, an appraisal is needed to clarify the strategic problem and alternative solutions. Full-scale construction projects and simple solutions (do-minimum alternatives) should be assessed. ... -
