Real-time computing of power flows and node voltages in electrical energy network using decision trees
(Peer reviewed; Journal article, 2023)In sustainable operation of electrical energy network, it is necessary to compute in real-time power flows and voltages at nodes for prioritizing power injection from clean energy resources. Intermittent renewable energy ... -
Real-Time Detection of Incipient Inter-Turn Short Circuit and Sensor Faults in Permanent Magnet Synchronous Motor Drives Based on Generalized Likelihood Ratio Test and Structural Analysis
(Peer reviewed; Journal article, 2022)This paper presents a robust model-based technique to detect multiple faults in permanent magnet synchronous motors (PMSMs), namely inter-turn short circuit (ITSC) and encoder faults. The proposed model is based on a ... -
Real-Time Fault Diagnosis of Permanent Magnet Synchronous Motor and Drive System
(Doctoral Dissertations at the University of Agder; no. 414, Doctoral thesis, 2023)Permanent Magnet Synchronous Motors (PMSMs) have gained massive popularity in industrial applications such as electric vehicles, robotic systems, and offshore industries due to their merits of efficiency, power density, ... -
A Reappraisal of Resilience in Digital Infrastructure: A Study of Cyber-Physical-Social Systems in Ongoing Crises
(Doctoral dissertations at University of Agder;471, Doctoral thesis, 2024)Digital technologies are now entrenched in the core operations of organisations providing critical services (OCSs). This is due to ongoing innovations in work and practice. As new applications and services are developed, ... -
Reason-based deference or ethnocentric inclusivity? Avery Kolers, Richard Rorty, and the motivational force of global solidarity
(Peer reviewed; Journal article, 2022)This article uses what Patti Tamara Lenard refers to as the cosmopolitan problem of motivation to discuss the roles of loyalty in two philosophical accounts of global solidarity. Avery Kolers’ Kantian, deontological approach ... -
'Reasoning' in national curricula and standards
(Chapter; Peer reviewed, 2022)The differing meanings and usages of terms related to argumentation and proof have been discussed in the literature and related to differences in language (e.g., Sekiguchi & Miyazaki, 2000), professional context (e.g., ... -
Recalibrating EU Foreign Policy vis-à-vis Central Asia: Towards Principled Pragmatism and Resilience
(Peer reviewed; Journal article, 2022)With China and Russia acting more assertively vis-à-vis Central Asia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan have gradually moved to the core of contemporary Eurasian geopolitics – albeit to varying ... -
Receiver-Initiated Data Collection in Wake-Up Radio Enabled mIoT Networks: Achieving Collision-Free Transmissions by Hashing and Partitioning
(Journal article; Peer reviewed, 2021)To achieve ultra-low energy consumption and decade-long battery lifetime for Internet of Things (IoT) networks, wake-up radio (WuR) appears as an eminent solution. While keeping devices in deep sleep for most of the time, ... -
