Onset of water accumulation in oil/water pipe flow – experiments and modelling with LedaFlow
(Peer reviewed; Journal article, 2020)In oil/water flows with very low water rates, the steady-state water fraction jumps discontinuously from a low value to a high value when the oil rate falls below the critical value. This jump is understood to be connected ... -
Optical and Electrochemical Characterisation of Carbon Anodes with Varying Porosity and Coke Quality
(Peer reviewed; Journal article, 2022)The performance of carbon anodes in aluminium production will depend on both the coke quality (impurities, structure) and the physical properties of the anode (density, permeability, electric resistivity). Here, a set of ... -
Optimal deployment of energy services for economic upliftment of low-income communities: A South African case study
(Peer reviewed; Journal article, 2023)Low-income communities face a causality dilemma: A lack of energy services hampers income growth and insufficient income hampers energy service provision. Interventions delivering cost-effective energy services can address ... -
Optimal preventive policies for parallel systems using Markov decision process: application to an offshore power plant
(Peer reviewed; Journal article, 2023)This work proposes a Markov Decision Process (MDP) model for identifying windows of opportunities to perform preventive maintenance for multi-unit parallel systems subject to a varying demand. The main contribution lies ... -
Optimisation of cutting parameters for improving energy efficiency in machining process
(Journal article; Peer reviewed, 2019)Reducing the machining energy consumption (MEC) of machine tools for turning operations is significant to promote sustainable manufacturing. It has been approved that selecting optimal cutting (turning) parameters is an ... -
Optimising Nurse Staffing at the Emergency Department of Ålesund Sykehus
(SINTEF Rapport;2024:00041, Research report, 2024)This report summarises the initiatives undertaken in the Emergency Department (ED) of Ålesund sykehus to enhance patient care and theworkday for nurses. The objective was two-fold and involved addressing nurse understaffing ... -
An optimization model for the planning of offshore plug and abandonment campaigns
(Peer reviewed; Journal article, 2019)Plug and abandonment (P&A) operations can be time-consuming and thus very costly, especially for subsea fields. P&A of subsea wells require dedicated vessels such as high cost semi-submersible drilling rigs or lower cost ... -
Optimization of FK-506 production in Streptomyces tsukubaensis by modulation of Crp-mediated regulation
(Peer reviewed; Journal article, 2023)FK-506 is a potent immunosuppressive macrocyclic polyketide with growing pharmaceutical interest, produced by Streptomyces tsukubaensis. However, due to low levels synthesized by the wild-type strain, biotechnological ... -
Optimization of Laser Metal Deposition Process for 2205 Duplex Stainless Steel
