Machine Learning in Python for Weather Forecast based on Freely Available Weather Data
(Journal article; Peer reviewed, 2018)Forecasting weather conditions is important for, e.g., operation of hydro power plants and for flood management. Mechanistic models are known to be computationally demanding. Hence, it is of interest to develop models that ... -
Markov Chain Monte Carlo Methods Applied to a Synchronous Generator Model
(Peer reviewed; Journal article, 2023)Markov Chain Monte Carlo (MCMC) approaches are widely used for tuning model parameters to fit process measurements. While modern probabilistic programming languages (PPLs) such as Stan, PyMC, and Turing have made it easier ... -
Mathematical modelling of mass transfer of paramagnetic ions through an inert membrane by the transient magnetic concentration gradient force. https://
(Peer reviewed; Journal article, 2020)The objective of this work is to suggest a mathematical model for mass-transfer of a paramagnetic electrolyte, nickel(ii)chloride solution, through an inert, thin membrane from one chamber to another under the influence ... -
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). ... -
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 ... -
Microevolutionary system identification and climate response predictions by use of BLUP prediction error method
(Peer reviewed; Journal article, 2023)Animals and other organisms in wild populations may adjust to climate change by means of plasticity and evolution, and it is an important task to find the contributions from each of these effects. Attempts to solve this ... -
Mixture of term assignments, tutorials, laboratory assignments and problem based learning for masters degree in engineering: an alternative to traditional learning and examination forms
(Conference report, 1999)We look at a course as a process of continuous learning and assessment of knowledge transfer to the students. In this context, we use a mixture of term assignments, tutorials, laboratory assignments and Problem Based ... -
Model based control for run-of-river system. Part 1: Model implementation and tuning
(Journal article; Peer reviewed, 2015)Optimal operation and control of a run-of-river hydro power plant depends on good knowledge of the elements of the plant in the form of models. River reaches are often considered shallow channels with free surfaces. A ... -
Model based control for run-of-river system. Part 2: Comparison of control structures
(Journal article; Peer reviewed, 2015)Optimal operation and control of a run-of-river hydro power plant depend on good knowledge of the elements of the plant in the form of models. Both the control architecture of the system, i.e. the choice of inputs and ... -
Model Based Early Kick/Loss Detection and Attenuation with Topside Sensing in Managed Pressure Drilling
(Peer reviewed; Journal article, 2020)Early kick/loss detection is a crucial part of safe well control, and it plays a major role in the reduction of risk and non-productive time in drilling. In conventional drilling, topside sensing is used for early kick/loss ... -
Model based flow measurement using venturi umes for return flow during drilling
(Journal article; Peer reviewed, 2017)In an oil well drilling operation, a proper knowledge of the return fluid flowrate is necessary both for the stabilization of the bottom hole pressure of the well and also as a primary indication of a kick or loss. In ... -
Model Predictive Control with Integral Action: A simple MPC algorithm
(Journal article; Peer reviewed, 2013)A simple Model Predictive Control (MPC) algorithm of velocity (incremental) form is presented. The proposed MPC controller is insensitive to slowly varying system and measurement trends and therefore has integral action. ... -
Model-free optimal anti-slug control of a well-pipeline-riser in the K-Spice/LedaFlow simulator
(Journal article; Peer reviewed, 2015)Simplified models are developed for a 3-phase well-pipeline-riser and tested together with a high fidelity dynamic model built in K-Spice and LedaFlow. These models are developed from a subspace algorithm, i.e. Deterministic ... -
Model-Free PI/PID Controller Tuning of Higher Order Nonlinear Dynamic Systems
(Peer reviewed; Journal article, 2019)This paper concerns model-free PI/PID controller tuning of possible (nonlinear) higher order systems. The method can be considered as a three-step procedure. The first step is to persistently excite the system in open loop ... -
