Hysteresis characteristic in the hump region of a pump-turbine model
(Peer reviewed; Journal article, 2016)The hump feature is one of the major instabilities in pump-turbines. When pump-turbines operate in the hump region, strong noise and serious fluctuations can be observed, which are harmful to their safe and stable operation ... -
Hysteresis of Natural Magnetite Ensembles: Micromagnetics of Silicate‐Hosted Magnetite Inclusions Based on Focused‐Ion‐Beam Nanotomography
(Peer reviewed; Journal article, 2020)Three‐dimensional geometries of silicate‐hosted magnetic inclusions from the Harcus intrusion, South Australia have been determined using focused‐ion‐beam nanotomography (FIB‐nt). By developing an effective workflow, the ... -
Hysteretic Control Lyapunov Functions with Application to Global Asymptotic Tracking for Underwater Vehicles
(Chapter, 2021)This paper introduces hysteretic control Lyapunov functions (HCLFs) for hybrid feedback control of a class of continuous-time systems. A family of HCLFs consists of local control Lyapunov functions defined on open domains, ... -
Høydeinterpolering av klimaparametere i nye aktsomhetskart for snøskred i Norge (NAKSIN)
(Master thesis, 2020)NAKSIN (Nye aktsomhetskart for snøskred i Norge) er et verktøy under utvikling/uttesting for å identifisere potensielt skredfarlige områder med hensyn på snøskred. Verktøyet har som mål å skulle erstatte det eksisterende ... -
Høydekartlegging for FKB-bygning med drone
(Bachelor thesis, 2021)Oppgaven har sett på muligheten for å kunne utføre kartlegging for Felles Kartdatabase (FKB) ved hjelp av bilder fra dronekartlegging. Det er tatt utgangspunkt i to eksisterende bildedatasett fra to ulike droner; DJI Mavic ... -
Høyproduktiv fresing av nikkelbaselegeringer
(Master thesis, 2010)This Master thesis consists of a literature review on surface integrity after milling with ceramic tools in nickel‐based super alloys. Examples of turning and milling with carbide tools have also been included, due to ... -
Høytemperatur varmepumpe for redusert energibruk i næringsmiddelbedrift
(Master thesis, 2018)Industriens andel av det totale energiforbruk er betydeleg. I Europa er denne om lag 30%, og situasjonen er omtrent den same i Noreg. Næringsmiddelindustrien er ein betydeleg del-sektor i så måte, om ikkje den største. I ... -
Høytemperatur varmepumper for industrielle anvendelser
(Master thesis, 2013)Industrielle varmepumper er effektivt integrert i varmegjenvinningssystemer ved lav temperatur, men tas sjelden i bruk når varmebehovet i gjenvinningsprosessene overstiger 100°C. Dersom industrielle varmepumper kan utnyttes ... -
I hvilken grad kan digitalisering føre til økt produktivitet?
(Master thesis, 2019)Produktivitet er et omdiskutert tema i byggeindustrien, hvor det ofte blir poengtert at denne bransjen har lavest produktivitetsvekst sammenlignet med andre næringene. Dette kommer mye av at bygg- og anleggsbransjen er en ... -
