Multiphase flow estimation using accelerometers, ultrasonic sensors, and machine learning
(Master thesis, 2022)The new sensors, accelerometers, and ultrasonic sensors were installed in the existing multimodal sensor suite used in the multiphase flow in the process hall in Campus Porsgrunn of USN. Multiphase flow experiments were ... -
Multiphase Flow Metering with Multimodal Sensor Suite for Identification of Flow Regimes, and Estimation of Phase Fractions and Velocities
(Master thesis, 2023)In this Master Thesis, data-driven multiphase flow metering models are developed to classify flow regimes and to estimate phase fractions and velocities of two-phase air/water flow after collecting data from the horizontal ... -
Multiphase flow metering – estimation of flow velocities of component phases using multimodal sensor suite
(Master thesis, 2022)There are many good alternatives to measure single-phase flow with high accuracy, but measuring multiphase flow is challenging. The sand detectors used on Equinor’s oil and gas installations use a piezoelectric sensor to ... -
Multipion Bose-Einstein correlations in pp,p -Pb, and Pb-Pb collisions at energies available at the CERN Large Hadron Collider
(Journal article; Peer reviewed, 2016)Three- and four-pionBose-Einstein correlations are presented in pp, p-Pb, and Pb-Pb collisions at the LHC.We compare our measured four-pion correlations to the expectation derived from two- and three-pion measurements. ... -
Multiple choice as formative assessment in dental education
(Peer reviewed; Journal article, 2024)Introduction: The effectiveness of multiple-choice questions (MCQs) in dental education is pivotal to student performance and knowledge advancement. However, their optimal implementation requires exploration to enhance the ... -
Multiple Spaces, Multiple Selves? The Case of King Sverrir of Norway
(Chapter, 2020)This article discusses the ways King Sverrir Sigurðarson of Norway (r. 1177–1202) perceived and represented himself. It seeks to move beyond the debate on whether he was mainly a leader of warriors who sought recognition ... -
Multiplicity and transverse momentum evolution of charge-dependent correlations in pp, p-Pb, and Pb-Pb collisions at the LHC
(Journal article; Peer reviewed, 2016)We report on two-particle charge-dependent correlations in pp, p–Pb, and Pb–Pb collisions as a function of the pseudorapidity and azimuthal angle difference, Δη and Δφ respectively. These correlations are studied using the ... -
Multiplicity dependence of (anti-)deuteron production in pp collisions at √s=7 TeV
(Journal article; Peer reviewed, 2019)In this letter, the production of deuterons and anti-deuterons in pp collisions at √s=7TeV is studied as a function of the charged-particle multiplicity density at mid-rapidity with the ALICE detector at the LHC. Production ... -
