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 ... -
