Dynamic electrochemical impedance spectroscopy, for electrocatalytic reactions
(Journal article; Peer reviewed, 2014)Dynamic electrochemical impedance spectroscopy with the ac signal applied while sweeping the potential is a powerful method to study reaction mechanisms of surface electrochemical reactions. The ability to reliably measure ... -
Dynamic electrochemical impedance study of methanol oxidation at Pt at elevated temperatures
(Journal article; Peer reviewed, 2019)The methanol oxidation reaction (MOR) is studied at temperatures up to 140 °C by a combination of cyclic voltammetry, chronoamperometry, and dynamic electrochemical impedance spectroscopy (dEIS). A mechanistic analysis of ... -
Dynamic Extremum Seeking Control Using ARX model
(Master thesis, 2018)In the design of the dynamic ESC, a wave perturbation is decided to be not a sinusoidal wave but a pseudo-random binary sequence(PRBS) wave. The reason behind this is that diverse frequencies in the PRBS wave make the ARX ... -
Dynamic Light Modulation in an Electrochromic Window consisting of Polyaniline, Tungsten Oxide and a Solid Polymer Electrolyte
(Journal article; Peer reviewed, 1993)The electrochemical and optical properties of an electrochromic window consisting of the two complementary electrochromic materials, polyaniline (PANI) and tungsten oxide (WO3), have been investigated. Both PANI and WO3 ... -

Dynamic Light Scattering Based Microrheology of End-Functionalised Triblock Copolymer Solutions
(Peer reviewed; Journal article, 2023)Nano-sized particles functionalised with short single-stranded (ss)DNAs can act as detectors of complementary DNA strands. Here we consider tri-block-copolymer-based, self-assembling DNA-coated nanoparticles. The copolymers ... -
Dynamic Micro-CT utilising Golden Ratio Sampling and Three-dimensional Generative Adversarial Networks
(Master thesis, 2023)Temporal datatomografi, dynamisk datatomografi, eller bare 4D-CT, er en røntgenavbildningsteknikk hvor tredimensjonale dynamiske prosesser kan avbildes. Ulempen med CT er de mange projeksjonene som kreves for å rekonstruere ... -

Dynamic modeling and optimalization of the cheese making procedure
(Master thesis, 2017)This thesis has successfully derived an dynamic model based on analytic solutions for production of semi-hard cheeses on the basis of raw milk from the cattle breed Norwegian red. The main emphasis has been to create a ... -
Dynamic modeling of the solvent regeneration part of a CO2 capture plant
(Journal article; Peer reviewed, 2013)In this work, a system of unit operations is modeled and implemented in MATLAB for dynamic simulation of the regeneration part of the CO2 capture process. The system consists of a stripper, a reboiler and a condenser, and ... -
Dynamic modelling of a Hydrocracker
(Master thesis, 2016)Different types of petroleum refining processes were considered to be modelled in the Kongsberg dynamic modelling software K-Spice. Multiple oil and gas processing units exist in the model library, which begs the question ... -
Dynamic Modelling of Heat and Mass Transfer in the Silicon Arc Furnace
(Master thesis, 2019)Grunstoffet silisium er av stor betydning for det moderne samfunn. Selv om silisium er det vanligtse grunnstoffet i jordskorpen etter oksygen, så finnes ikke silisium i sin elementære form i naturen. Silisium kan produseres ... -
Dynamic Optimization and Parameter Estimation used on an Extrusion Press for Aluminium
(Master thesis, 2022)I dag blir aluminium brukt i flere og flere produkter. Noen av disse, som radiatoren i moderne biler, krever veldig presise produksjonsmetoder. Her brukes tynne, hule profiler som varmevekslere, og de produseres ved ... -
