Comparison of simulation tools for dynamic models
(Journal article; Peer reviewed, 2018)Macroscopic models are used extensively in process engineering, and can often be posed as DAE (Differential Algebraic Equation) models. Three generic tools for solving such DAEs are compared: OpenModelica, Julia, and MATLAB. ... -
Comparison of space heating energy consumption of residential buildings based on traditional and model-based techniques
(Journal article; Peer reviewed, 2017) -
Compression into two-component PLS factorizations
(Journal article; Peer reviewed, 2003)Partial least squares regression (PLSR) often requires more than two components also in the case of a scalar response variable. As shown in papers on orthogonal signal correction (OSC), it is possible to reduce the number ... -
Computational fluid dynamics study of flow depth in an open Venturi channel for Newtonian fluid
(Journal article; Peer reviewed, 2017)Open Venturi channel flow measurement could be a cheap method to be used in drill bit pressure control. The main objective of this study is to identify the factors related with the flow depth in an open Venturi channel. A ... -
Computational Fluid Dynamics Study of Shear Thinning Fluid (Drilling Fluid) Viscosity Models in an Open Venturi Channel
(Journal article; Peer reviewed, 2019)We aim to develop an improved kick/loss detection technology by developing smart flow-sensor technology for returned flow from the oil well in open Venturi channels. This is a detailed study about a capacity of use of ... -
Computational Fluid Dynamics Study of the Effects of Drill Cuttings on the Open Channel Flow
(Peer reviewed; Journal article, 2019)A three-dimensional computational fluid dynamics (CFD) study was carried out for drilling fluid flow with drill cuttings in open channels. The flow is similar to the return flow when drilling, stream containing drilling ... -
Constrained numerical optimization of PCR/PLSR predictors
(Journal article; Peer reviewed, 2003)Assuming a fully known latent variables (LV) model, the optimal multivariate calibration predictor is found from Kalman filtering theory. From this follows the best possible column space for a loading weight matrix Wopt. ... -
Contact Resistance and Temperature Rise of Cable Connections in Cable Distribution Cabinets
(Conference lecture, 2020)Initiated by a number of fire accidents in the low voltage switchgear in cable distribution cabinets, investigations have been performed to identify the cause of these fires. The results indicate that the cable connection ... -
Control of a Buoyancy-Based Pilot Underwater Lifting Body
(Journal article, 2010)This paper is about position control of a speci c small-scale pilot underwater lifting body where the lifting force stems from buoyancy adjusted with an air pocket in the lifting body. A mathematical model is developed to ... -
Control of temperature and energy consumption in buildings - a review.
(Journal article; Peer reviewed, 2014)Building sector is one of the largest energy consumers in the world and currently it utilizes 40% of the total energy in the European Union. At the beginning of the article, energy crisis related to the buildings is defined ... -
Controller Design for a Magnetic Levitation Kit using OpenModelica’s Integration with the Julia Language
(Peer reviewed; Journal article, 2019)This paper presents a practical application of computer aided control systems design using a new OpenModelica API (OMJulia) which allows to conveniently operate on Modelica models from the Julia language. Julia is a rather ... -
Cooperative learning at Telemark State University : the student's verdict
(Conference object, 1996)The Engineering College of Høgskolen i Telemark has practiced cooperative learning since 1982. As seen from the college, this way of administering the students' work appears powerful. After briefly having described the ... -
Covering the Gap Between Advanced Control Theory Design and Real Time Implementation Using Simulink
(Journal article; Peer reviewed, 2017)New developments in sensor technology and control actuators make it viable to monitor and regulate more process variables, providing an opportunity to apply advanced multivariable control techniques. Although modern control ... -
