A Trajectory-Driven 3D Non-Stationary mm-Wave MIMO Channel Model for a Single Moving Point Scatterer
(Peer reviewed; Journal article, 2021)This paper proposes a new non-stationary three-dimensional (3D) channel model for a physical millimeter wave (mm-Wave) multiple-input multiple-output (MIMO) channel. This MIMO channel model is driven by the trajectory of ... -
Fault Detection and Diagnostics of Hydraulic Systems in Hydroelectric Power Plants
(Master thesis, 2023)Most hydroelectric power plants experience few faults during their lifetime. However, with the expected increase in volatile energy sources in the energy mix and the use of hydroelectric power plants as balancing mechanisms, ... -
Preserving the Past, Powering the Future: Energy Efficiency and Renewables in Norway's Wooden Churches
(Master thesis, 2023)This master’s thesis explores the potential for energy efficiency in three wooden churches built in the 19th century in the southern part of Norway. Specifically, the thesis focuses on the three churches Eide, Landvik, and ... -
A computational framework for coating fatigue analysis of wind turbine blades due to rain erosion
(Peer reviewed; Journal article, 2021)The rain-induced fatigue damage in the wind turbine blade coating has attracted increasing attention owing to significant repair and maintenance costs. The present paper develops an improved computational framework for ... -
Unified Quality-Aware Compression and Pulse-Respiration Rates Estimation Framework for Reducing Energy Consumption and False Alarms of Wearable PPG Monitoring Devices
(Peer reviewed; Journal article, 2023)Due to the high demands of tiny, compact, lightweight, and low-cost photoplethysmogram (PPG) monitoring devices, these devices are resource-constrained including limited battery power. Consequently, it highly demands ... -
Using transfer coefficients to model series-connected multi-junction solarcells with radiative coupling
(Peer reviewed; Journal article, 2023)When the quality of multi-junction solar cells becomes sufficiently high, radiative exchange of photons between cells must be included to properly model such devices. In this work, it is shown how constants called transfer ... -
Augmented Random Search with Artificial Neural Networks for energy cost optimization with battery control
(Peer reviewed; Journal article, 2022)Intermittent renewable energy production and dynamic load must be balanced through appropriate control of integrated energy storage to account for the temporal discrepancy among power supply and demand. Intelligent control ... -
Calibration of the HMPID detector at the ALICE experiment
