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 energy system with a local LTTG at Leangen
(Master thesis, 2020)Denne masteroppgaven er en fortsettelse av en tidligere prosjektoppgave og evaluerer bruken av spill-varmekilder for å lage varmtvann til et leilighetsområde. Hovedfokuset er på en oversvømmet fordamper og en CO2 varmepumpe ... -
Dynamic Estimation for Controlling a Subsea Production System - Virtual Flow Metering using B-spline Surrogate Models
(Master thesis, 2014)Knowledge of the flow rates from individual wells in a subsea production system can greatly improve decision-making processes. This thesis investigates flow estimation in the subsea template Tilje in the BP-operated Skarv ... -
Dynamic Estimators Using Laser and Ultrasonic Instrumentation for Determining the Metal and Bath Heights in Aluminium Electrolysis Cells A combination of hard/soft sensor approach
(Doctoral thesis at NTNU;2015:15, Doctoral thesis, 2015) -
Dynamic exploration designs for graphical models using clustering with applications to petroleum exploration
(Journal article, 2014)The paper considers the problem of optimal sequential design for graphical models. Oil and gas exploration is the main application. Here, the outcomes at prospects or reservoir units are highly dependent on each other. The ... -
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 Factor Modelling of Major Norwegian Export Commodities - Decomposing and forecasting the price movements of Atlantic salmon and Brent Crude oil
(Master thesis, 2018)This thesis studies the price movements of two major Norwegian export commodities, Atlantic salmon and Brent Crude oil, using a dynamic factor modelling approach. We pursue two different avenues of research, namely co-movement ... -
Dynamic fault-detection in shipboard electric load sharing.
(Master thesis, 2013)The main contribution of this thesis is an investigation of dierent fault detection systems that canbe used for marine diesel electric power plants.The motivation of this thesis is to develop fault detection systems that ... -
Dynamic FE-Analysis of a Vibration Damping Tool
(Master thesis, 2020) -
Dynamic Gate Controlled Power Amplifier Design Based on GaN Technology.
(Master thesis, 2015)In this thesis, a harmonic tuned amplifier has been designed and manufactured to investigate if Dynamic Gate Control can be utilized to obtain greater linearity properties. The design process has been conducted with the ... -
Dynamic Graph Topology Learning with Non-Convex Penalties
(Chapter, 2022)This paper presents a majorization-minimization-based framework for learning time-varying graphs from spatial-temporal measurements with non-convex penalties. The proposed approach infers time-varying graphs by using the ... -
Dynamic Hedging for a Norwegian Hydropower Producer - Electricity prices, inflow and currency risk
(Master thesis, 2018)This master's thesis consists of two articles. In the first article, we present a global, dynamic model for hedging of hydropower production. We include stochastic processes for spot and futures prices, reservoir inflow ... -
Dynamic hedging for the real option management of hydropower production with exchange rate risks
(Journal article; Peer reviewed, 2023)We study the risk management problem of a hydropower producer that hedges risk by trading currency and power futures contracts. The model considers three types of risks: operational risk due to supply uncertainty, profit ... -
Dynamic High Frequency Trading Models
(Master thesis, 2009)This thesis considers constructing high-frequency quantitative trading models. The work is a continuation of my project thesis (spring 2009) and Birgitte Ringstad Vartdal's master thesis (2000). We build our trading model ... -
Dynamic Identification and Modelling of a Pantograph
(Master thesis, 2018)The main objective of this thesis is to measure and determine the dynamic properties of a measurement pantograph, and then create a numerical model with the same properties. The purpose of the model is to give a better ... -
Dynamic impact of heavy long vehicles with equally spaced axles on short-span highway bridges
(Journal article; Peer reviewed, 2018)Extremely large trucks with a weight exceeding the standard require a permit before they are allowed to cross the bridges of a specific route. For the purpose of safety, an escort is often ... -
Dynamic incorporation of nonlinearity into MILP formulation for short-term hydro scheduling
(Journal article; Peer reviewed, 2019)Optimization tools are widely used for solving the short-term hydro scheduling (STHS) problem in a cascaded hydro system. In a mixed integer linear programming (MILP)-based formulation, the nonlinear and non-convex hydropower ... -
Dynamic indexes vs. static hierarchies for substring search
(Master thesis, 2005)This report explores the problem of substring search in a dynamic document set. The operations supported are document inclusion, document removal and queries. This is a well explored field for word indexes, but not for ... -
Dynamic job assignment: A column generation approach with an application to surgery allocation
(Journal article; Peer reviewed, 2018)We consider the assignment of jobs to heterogeneous agents in a dynamic system with a rolling time horizon. An example is a hospital operating theatre where the jobs are surgeries and the agents are the surgeons. The paper ... -
