Vertical Approach Anomaly Detection Using Local Outlier Factor
(Chapter; Peer reviewed, 2023)Detection of anomalies based on smart meter data is crucial to identify potential risks and unusual events at an early stage. In addition anomaly detection can be used as a tool to detect unwanted outliers, caused by ... -
Vibration control of a base-isolated building using wavelets
(Chapter; Peer reviewed, 2011)This paper proposes a numerical approach for finding an optimal control based on wavelet functions for vibration reduction of a base-isolated building subjected to actual earthquakes. The objective is two-fold: (1) to find ... -
Vibration control of base-isolated structures using mixed H-2/H-infinity output-feedback control
(Journal article; Peer reviewed, 2009)A mixed H-2/H-infinity output-feedback control design methodology for vibration reduction of base-isolated building structures modelled in the form of second-order linear systems is presented. Sufficient conditions for the ... -
Violation-mitigation-based method for PV hosting capacity quantification in low voltage grids
(Peer reviewed; Journal article, 2022)Hosting capacity knowledge is of great importance for distribution utilities to assess the amount of PV capacity possible to accommodate without troubling the operation of the grid. In this paper, a novel method to quantify ... -
Virtual Sensing of Load Forces in Hydraulic Actuators using Second- and Higher-Order Sliding Modes
(Journal article; Peer reviewed, 2019)External load forces are challenging for sensing or estimating in the hydraulic actuators. Once it is due to inconvenient instrumentation of the force sensors, especially on an open-end mechanical interface. The other way, ... -
Viscoelastic characterization and comparison of Norwegian asphalt mixtures using dynamic modulus and IDT tests
(Chapter; Peer reviewed, 2021)This paper presents the comparison of stiffnesses of two types of asphalt concrete mixes (Ab11 and Agb11) fabricated in the laboratory using two commonly used stiffness tests. (1) uniaxial compression dynamic modulus (E*) ... -
Voltage Source Multilevel Inverters with Reduced Device Count: Topological Review and Novel Comparative Factors
(Peer reviewed; Journal article, 2020)Multilevel inverters (MLIs) have gained increasing interest for advanced energy-conversion systems due to their features of high-quality produced waveforms, modularity, transformerless operation, voltage, and current ... -
Waste heat recovery from a marine waste incinerator using a thermoelectric generator
(Journal article; Peer reviewed, 2012)A marine waste incinerator has been evaluated for waste heat harvesting using thermoelectric generators (TEG). The application has been evaluated using mathematical modeling to optimize the heat exchanger and some vital ... -
What shapes Norwegian wind power policy? Analysing the constructing forces of policymaking and emerging questions of energy justice
(Peer reviewed; Journal article, 2021)This paper employs an assemblage theoretical approach to analyse how Norwegian land-based wind power policies are constructed over time and what forces dominate and resist wind power policy development. The entanglement ... -
Wi-Sense: a passive human activity recognition system using Wi-Fi and convolutional neural network and its integration in health information systems

Wind turbine modeling using the bond graph
(Chapter; Peer reviewed, 2011)This paper addresses the problem of bond graph methodology as a graphical approach for modeling wind turbine systems. In this case, we consider the modeling of a wind turbine system with individual pitch control scheme and ... -
Wind turbine pitch control and load mitigation using an l1 adaptive approach
(Journal article; Peer reviewed, 2014)We present an application of L1 adaptive output feedback control design to wind turbine collective pitch control and load mitigation. Our main objective is the design of an L1 output feedback controller without wind speed ... -
