Microevolutionary system identification and climate response predictions
(Peer reviewed; Journal article, 2022)Microevolutionary system identification was introduced Ergon (2022), with the specific purpose to show that predictions of genetic adaptations to climate change require that environmental reference values are properly ... -
Dynamical BLUP modeling of reaction norm evolution, accommodating changing environments, overlapping generations, and multivariate data
(Peer reviewed; Journal article, 2023)For theoretical studies, reaction norm evolution in a changing environment can be modeled by means of the multivariate breeder's equation, with the reaction norm parameters treated as traits in their own right. This is, ... -
Pedagogical Perspectives of Interdisciplinary Teaching and Research: An Energy System Modelling Outlook in Relation to Energy Informatics
(Peer reviewed; Journal article, 2023)The purpose of this paper is to present and discuss pedagogical frameworks and approaches to developing, delivering, and evaluating a new interdisciplinary course within the domain of energy informatics at both Master’s ... -
Detecting emergence in engineered systems: A literature review and synthesis approach
(Peer reviewed; Journal article, 2023)Modern product development often generates systems of high complexity that are prone to emergent behavior. The industry has a need to establish better practices to detect inherent emergent behavior when engineering such ... -
The important choice of reference environment in microevolutionary climate response predictions
(Peer reviewed; Journal article, 2022)It is well documented that individuals of wild populations can adjust to climate change by means of phenotypic plasticity, but few reports on adaptation by means of genetically based microevolution caused by selection. ... -
Applying Design of Experiments Method for the Verification of a Hydropower System
(Chapter, 2022)Today, renewable energy plays a major role in the transition towards environment-friendly energy sources. Hydropower is one of the most important renewable energy sources leading to the high interest of research associated ... -
Averaging level control for urban drainage system
(Peer reviewed; Journal article, 2021)In the work, averaging level control using model-based control and estimation algorithm on a buffer tank system is studied. Implementation of Model Predictive Control (MPC) and Proportional-Integral (PI) control together ... -
Detecting emergence in engineered systems: A literature review and synthesis approach
(Peer reviewed; Journal article, 2023)Modern product development often generates systems of high complexity that are prone to emergent behavior. The industry has a need to establish better practices to detect inherent emergent behavior when engineering such ... -
Ensemble learning in the estimation of flow types and velocities of individual phases in multiphase flow using non-intrusive accelerometers' and process pressure data
(Chapter, 2022)Multiphase flows with oil/ gas/ water are common in oil and gas industries. Accurately identifying flow types and estimating flow velocities of the individual phases are crucial for different purposes, such as observing ... -
Version [OpenIPSL 2.0.0] - [iTesla Power Systems Library (iPSL): A Modelica library for phasor time-domain simulations]
(Journal article; Peer reviewed, 2023)This paper describes Open-Instance Power System Library (OpenIPSL) version 2.0.0 and its most recent enhancements. This new version brings upgrades that include more robust models that are better documented, and example ... -
Mechanistic Model of an Air Cushion Surge Tank for Hydro Power Plants
(Peer reviewed; Journal article, 2022)Due to the increasing use of renewable energy sources, and to counter the effects of fossil fuels, renewable dispatchable hydro power can be used for balancing load and generation from intermittent sources (solar and wind). ... -
Developing Voltage Droop/Compensation Controller for a Hydro Power Controller in Modelica
(Peer reviewed; Journal article, 2022)With the introduction of unregulated renewable energy such as wind, solar and tidal power, the operation of the electrical grid has become more and more challenging. The more dynamic production pattern requires more advanced ... -
Stator Flux-Regulatory Excitation Control in Converter-Fed Synchronous Machines for Pumped-Storage Variable-Speed Hydropower
(Peer reviewed; Journal article, 2022)Pumped-storage hydropower is seen as a promising solution for efficient, large-scale energy storage. One competitive technical solution is the variable-speed hydropower plant (VSHP) configured with a converter-fed synchronous ... -
Water Care System (WCS) for Numeric Water Quality Criteria (NWQC) with IoT/IoUT–Educational Implications of Sustainability Goal SDG 14
(Chapter, 2022)In most developing countries and evolving countries, availability of potable water is scarce, and the water sources are very often unattended or unmonitored. Island states have the additional problems associated with ... -
Quantization Analysis and Robust Design for Distributed Graph Filters
(Journal article; Peer reviewed, 2021)Distributed graph filters have recently found appli- cations in wireless sensor networks (WSNs) to solve distributed tasks such as reaching consensus, signal denoising, and recon- struction. However, when implemented over ... -
Zonal Day-Ahead Energy Market: A Modified Version of the IEEE 39-bus Test System
