Machine Learning for Predicting Polarization Curves and Their Features
(Master thesis, 2023)Vanligvis er viktige elektrokjemiske parametere hentet fra empiriske data. Dette skyldes i stor grad at analytiske modeller, som ulike former av Butler-Volmer-ligningen, ofte kommer til kort i nøyaktig å fange de viktige ... -
Machine Learning Modelling of the Oxidative and Thermal Degradation of Monoethanolamine (MEA)
(Master thesis, 2021)Folketallet i verden vokser, noe som fører til en økning i forbruket av ressurser og utslipp av klimagasser. Som et resultat av dette øker konsentrasjonene av klimagasser i atmosfæren til farlige nivåer, og behovet for ... -
Machine-learned model Hamiltonian and strength of spin–orbit interaction in strained Mg2X (X = Si, Ge, Sn, Pb)
(Peer reviewed; Journal article, 2022)Machine-learned multi-orbital tight-binding (MMTB) Hamiltonian models have been developed to describe the electronic characteristics of intermetallic compounds Mg2Si, Mg2Ge, Mg2Sn, and Mg2Pb subject to strain. The MMTB ... -
Macro- and micro scale phenomena in gas flotation for produced water treatment- the effect of fluid composition, temperature and pressure
(Doctoral theses at NTNU;2023:369, Doctoral thesis, 2023)Produced water, the primary waste product of the petroleum industry, contains harmful components that must be treated before discharge to the sea or reinjection. The focus of treatment has traditionally been on dispersed ... -
Macroalgal detritus: Physical variables and impacts on the benthic macrofaunal community
(Master thesis, 2018)Marine primary productivity by micro- and macroalgae in Norway, limited to the photic zone (0 200 m depth), controls the amount of organic carbon (food) available to higher trophic levels, and is the basis for marine ... -
MacroBiomass En kompetansebase for industriell taredyrking
(Research report, 2013)MacroBiomass Prosjektet MacroBiomass har hatt som mål å bygge en kompetansebase med fokus på biologiske utfordringer i storskala dyrking av makroalger (tare) til bioenergi. Prosjektet har jobbet med hele produksjonssyklusen ... -
Macroclimatic structuring of spatial phylogenetic turnover in liverworts
(Peer reviewed; Journal article, 2021)Phylogenetic turnover has emerged as a powerful tool to identify the mechanisms by which biological communities assemble. When significantly structured along environmental gradients, phylogenetic turnover evidences ... -
Macromolecular acidic coating increases shelf life by inhibition of bacterial growth
(Journal article; Peer reviewed, 2018)The sensitivity of microorganisms to low pH can be utilized in food protection by preparing coatings based on macromolecular acids. Due to limited diffusivity of macromolecules low pH occurs primarily at the surface, while ... -
Macromolecular characterisation of lignosulfonates and their interactions with chitosans
