High current arc erosion on copper electrodes in air
(Journal article; Peer reviewed, 2011)An arc fault inside metal enclosed switchgear will cause the pressure to rise and vaporization of electrode material may contribute to the pressure rise. An experimental study of high current arc erosion on copper electrodes ... -
High Speed EIT with Multifrequency Excitation Using FPGA and Response Analysis Using FDM
(Peer reviewed; Journal article, 2020)The investigation of quickly-evolving flow patterns in high-pressure and higherature flow rigs is crucial due to inherent hazards. There is a dire need for a high-speed, non-intrusive imaging technique to identify ... -
Human behaviour modelling for welfare technology using hidden Markov models
(Peer reviewed; Journal article, 2019)Human behaviour modelling for welfare technology is the task of recognizing a person's behaviour patterns in order to construct a safe environment for that person. It is useful in building environments for older adults or ... -
Hybrid Model Predictive Control Scheme for Controlling Temperature in Building Under Uncertainties
(Peer reviewed; Journal article, 2023)This paper presents a study on temperature control with a heater in a building using Model Predictive Control (MPC) with a focus on addressing two uncertainties: in model and the weather forecast. In previous works, a ... -
Hydropower Systems: Comparison of Mechanistic and Table Look-up Turbine Models
(Journal article; Peer reviewed, 2017)In this paper, a detailed overview of hydropower system components is given. Components of the system include intake race, upstream and downstream surge tanks, penstock, turbine and draft tube. A case study which includes ... -
Impact Study of Temperature on the Time Series Electricity Demand of Urban Nepal for Short-Term Load Forecasting
(Journal article; Peer reviewed, 2021)Short-term electricity demand forecasting is one of the best ways to understand the changing characteristics of demand that helps to make important decisions regarding load flow analysis, preventing imbalance in generation ... -
Implementation of simplified sequential stochastic model predictive control for operation of hydropower system under uncertainty
(Peer reviewed; Journal article, 2023)Sequential stochastic model predictive control (MPC) is a control framework that sequentially employs two optimizers. The high-level optimizer generates a coarse long-term plan based on nominal uncertainty values, while ... -
Implementing an Extended Kalman Filter for estimating nutrient composition in a sequential batch MBBR pilot plant
(Journal article; Peer reviewed, 2019)Online monitoring of water quality parameters can provide better control over various operations in wastewater treatment plants. However, a lack of physical online sensors, the high price of the available online water-quality ... -

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. ... -
Improved model for solar heating of buildings
(Journal article; Peer reviewed, 2015-11-25)A considerable future increase in the global energy use is expected, and the effects of energy conversion on the climate are already observed. Future energy conversion should thus be based on resources that have negligible ... -
Improvement of the Frequency Response Indicators by Optimal UFLS Scheme Settings
(Peer reviewed; Journal article, 2020)This research investigates the positive changes in the system frequency response indicators caused by the implementation of a set of optimal settings of an under-frequency load shedding (UFLS) scheme. The optimal under-frequency ... -
Industry/college cooperation on undergraduate project work as a college revenue source
(Conference report, 2007)Since 1994, the Norwegian Ministry for Education and Research has required government supported universities and colleges to find additional sources of income. For Telemark University College (TUC) in Porsgrunn, senior ... -
Informative PLS score-loading plots for process understanding
(Journal article; Peer reviewed, 2004)Principal component regression (PCR) based on principal component analysis (PCA) and partial least squares regression (PLSR) are well known projection methods for analysis of multivariate data. They result in scores and ... -
Informative score-loading-contribution plots for multi-response process monitoring
(Journal article; Peer reviewed, 2009)The projection based multivariate data methods of principal component regression (PCR) and partial least squares regression (PLSR) are well established in the eld of process monitoring. Use of score and loading plots for ... -
Innovative primary frequency control in low‐inertia power systems based on wide‐area RoCoF sharing
(Journal article, 2020)Future plans for integration of large non-synchronous generation and the expansion of the power system in the Nordic countries are a concern to transmission system operators due to the common interconnections and electricity ... -
Interleaved high gain DC-DC converter for integrating solar PV source to DC bus
(Peer reviewed; Journal article, 2019)In this paper, a novel non-isolated DC-DC converter topology is proposed for solar photovoltaic (PV) application. The proposed converter is constructed from an interleaved boost converter (IBC) to reduce the input current ... -
Is engineering mathematics really an engineering tool?
(Conference report, 1999)A set of final exams at Telemark State University has been studied to check if there is a symbiotic relationship between the mathematical tool and some technical courses offered at the Electrical Engineering Department. ... -
