Damped steady-state resonant sloshing in a circular base container
(Journal article; Peer reviewed, 2018)To describe the damped resonant sloshing in a circular base container, the nonlinear modal equations by Faltinsen et al (2016 J. Fluid Mech. 804 608–45) are equipped with linear damping terms associated with the logarithmic ... -
Dampening of wood batch combustion heat release using a phase change material heat storage: Material selection and heat storage property optimization
(Journal article; Peer reviewed, 2016)The use of wood stoves for space heating in energy effective residential buildings can be problematic due to the batch combustion giving a highly transient heat production and the limited regulation of the combustion ... -
Dampgenerering i en solfanger
(Master thesis, 2013)Av praktiske og kulturelle årsaker har ikke tradisjonelle solkokere blitt implementert i landlige områder i afrikanske land. I områder med dårlig eller ikke-eksisterende strømnett blir mye tid brukt på å finne biodrivstoff ... -
Damping and Stiffness Characteristics of Shallow Offshore Foundations
(Master thesis, 2020)Målet med denne oppgaven er å etablere et enkelt rammeverk for å estimere fundamentnivåets demping og stivhet for grunne fundamenter i forskjellige jordtyper og med varierende fundamentgeometrier, uten å måtte utføre ... -
Damping in Timber Structures
(Doctoral Theses at NTNU, 1503-8181; 2012:263, Doctoral thesis, 2012)Key point to development of environmentally friendly timber structures, appropriate to urban ways of living, is the development of high-rise timber buildings. Comfort properties are nowadays one of the main limitations to ... -
Damping Measurements on a Multi-Blade Cascade with Multiple Degrees of Freedom: A Francis-99 Test Case
(Journal article; Peer reviewed, 2019)Due to thinner blades and higher demands for flexibility, the high-head Francis runners designed today face considerable challenges that severely affect the runners' expected lifetime. For many high-head Francis runners, ... -
Dampmotstand til klebefelt i kombinerte undertak og vindsperrer
(Master thesis, 2022)Strengere krav til tetthet og energibruk, samt økt fokus på bærekraft, har ført til at teip og klebede løsninger er hyppig brukt i moderne bygninger. Tetthet mot luft og fukt bidrar til beskyttelse av konstruksjonen slik ... -
Dannelse av sulfidforekomster i Reinfjord og Lokkarfjord, Seiland magmatiske provins - En svovelisotopstudie av økonomisk interessante sulfid-forekomster dannet i forbindelse med ultramafisk magmatisk aktivitet.
(Master thesis, 2013)En systematisk petrografisk-geokjemisk oversikt av sulfidforekomstene i Reinfjord (Troms) og Lokkarfjord (Finnmark) i Nord-Norge blir her gitt. Hensikten med oppgaven er å øke forståelsen for geologien i området, spesielt ... -
