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 ... -
Ice Abrasion and Bond Testing of Repair Mortars and High Performance Concrete
(Master thesis, 2013)The purpose of this thesis has been to investigate ice abrasion properties for three different repair mortars, and evaluate their behavior and properties in relation to a typical B60 offshore concrete and a B70 concrete. ... -
Ice abrasion of concrete, background theory and testing at the NTNU laboratory
(Master thesis, 2012)Ice abrasion has been reviewed. Concrete and ice and their most important properties in accordance to ice abrasion have been studied. Concrete strength and contact pressure between ice and concrete is found to be important ... -

Ice Abrasion on Fiber Reinforced Concrete: A Study on the Effects of Various Types of Fiber and the Reliability of the Laboratory Measurements
(Master thesis, 2014)The purpose of this study has been to compare how fiber reinforced concretes, using different amounts and types of fiber, behave compared to standard offshore concretes without fiber in regard to ice abrasion. The effect ... -
ICE ABRASION ON MARINE CONCRETE STRUCTURES
(Doctoral thesis at NTNU;2015:189, Doctoral thesis, 2015)A significant amount of the world’s undiscovered oil- and gas resources are located North of the Arctic Circle. In the light of this, there is currently an increasing interest in developing necessary infrastructure to ... -
Ice abrasion testing of high performance concrete for offshore structures
(Chapter, 2019)Offshore concrete structures exposed to drifting sea ice have abrasion of the concrete surface caused by the mechanical contact between ice and concrete in the order of 0.1 to 1 mm per year. The concrete-ice abrasion ... -
Ice abrasion testing of HP concrete for offshore structures
(Chapter, 2019)Offshore structures can be exposed to drifting sea ice. The wear (abrasion) of the concrete surface caused by the mechanical contact between ice and concrete is in the order of 0.1–1 mm per year. The concrete-ice abrasion ... -
Ice Actions on Offshore Structures – With Applications of Continuous Wavelet Transforms on Ice Load Signals
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:9, Doctoral thesis, 2006)Ice actions on offshore structures are one of the main concerns for engineering activities in cold areas with ice-infested waters. This thesis deals with three aspects of ice actions, namely design ice loads from level ... -
Ice and conical structure interactions
(Master thesis, 2010)The pursuit of energy in Arctic waters drives people to design ocean structures applying new concepts.Conical structures which shift the ice failure mode from crushing to bending could reduce the total iceload. Moreover, ... -
Ice and Ice Forces in Small Steep Rivers
(Doctoral theses at NTNU;2023:431, Doctoral thesis, 2023)English summary Given the right circumstances ice can wreak havoc on riverine infrastructure. Ice runs pushing ice floes against bridge piers is frequently the governing design condition for bridges in cold regions. The ... -
Ice breakup in small Norwegian streams
(Master thesis, 2013)River ice is present parts of the year in cold region environments and is an important component of the flow regime. The river ice is known to produce many extremes and potential floods far exceed those possible under ... -
Ice condition assessment using onboard accelerometers and statistical change detection
(Journal article; Peer reviewed, 2019)The presence of sea ice is the predominant risk for ship operations in the Arctic, and monitoring of ice condition around a vessel is crucial during all times of operation. This paper presents a system for online onboard ... -
