Preserving the Past, Powering the Future: Energy Efficiency and Renewables in Norway's Wooden Churches
(Master thesis, 2023)This master’s thesis explores the potential for energy efficiency in three wooden churches built in the 19th century in the southern part of Norway. Specifically, the thesis focuses on the three churches Eide, Landvik, and ... -
Pressure-flow dynamics with semi-stable limit cycles in hydraulic cylinder circuits
(Chapter, 2021)In hydraulic circuits of the standard fluid-power actuators and mechanisms, like the linear-stroke cylinders, some hydrodynamic effects are often neglected. It happens mainly due to their complexity and secondariness in ... -
Preventing early age chloride migration into low-carbon concrete
(Journal article; Peer reviewed, 2019)The use of substituting cementitious materials (SCMs) to produce low-carbon concrete is escalating. This contributes to reducing the anthropogenic emission of CO2, and to reduce harmful temperature gradients during cement ... -
A probabilistic long-term framework for site-specific erosionanalysis of wind turbine blades: A case study of 31 Dutch sites
(Peer reviewed; Journal article, 2021)Rain-induced leading-edge erosion (LEE) of wind turbine blades (WTBs) is associated with high repair and maintenance costs. The effects of LEE can be triggered in less than 1 to 2 years for some wind turbine sites, whereas ... -
Probabilistic models for the fatigue resistance of welded steel joints subjected to constant amplitude loading
(Peer reviewed; Journal article, 2021)S-N curves found in various rules and regulations are the basic tool for the practicing engineer when carrying out life predictions for welded details in dynamically loaded structures. The present work is investigating the ... -
A probabilistic rainfall model to estimate the leading-edge lifetime of wind turbine blade coating system
(Peer reviewed; Journal article, 2021)Rain-induced leading-edge erosion of wind turbine blades is associated with high repair and maintenance costs. For efficient operation and maintenance, erosion models are required that provide estimates of blade coating ... -
Process analysis of a biomass-based quad-generation plant for combined power, heat, cooling, and synthetic natural gas production

Prognosis of ball bearings with non-characteristic degradation using recurrent neural network
(Master thesis, 2019)Breakdowns in rotary machines are often related to bearing failure. In recentyears many prognostic and diagnostic models of bearings have been developedto prevent unexpected shutdowns. Estimating the remaining useful ... -
Proper sizing of energy storage for grid connected photovoltaic system
(Master thesis, 2014)The requirement of an energy storage to a grid connected PV system, is highly desirable in cases like power outages. Another importance is to reduce the peak time electricity buying from the utility grid and discharging ... -
Prosessorientert planlegging : Tverrfaglig analyse av flyt og forutsetninger i byggeprosjekter
(Master thesis, 2018)Introduction: The construction industry is undergoing constant changes and the complexity of today’s buildings is increasing. Simultaneously, there is a constant pressure to deliver projects faster and cheaper, without ... -
PSIM-Based Hardware and Software Design of an Inverter-Fed Permanent Magnet Synchronous Motor
(Master thesis, 2018)The purpose of this research is to design a PSIM based controller for an inverter-fed Permanent Magnet Synchronous Motor (PMSM). The dimensioning and assembly of the controller are presented. The control algorithm used ... -
Pump controlled hydraulic cylinder with large inertia loads
(Master thesis, 2021)This thesis is centered around the commissioning, testing, modeling and experimental validation of a pump-controlled hydraulic actuator capable of controlling large inertia loads. Prior to the thesis an experimental test ... -
Pyrolyse i avløpshåndtering og utvinning av biokull
(Master thesis, 2023)This thesis has investigated if pyrolysis is a sustainable solution for the treatment of sewage sludge for Horten Municipality. Separate laboratory experiments and literature research was executed to answer the research ... -
Pyrolytic formation of polycyclic aromatic hydrocarbons from sesquiterpenes
(Journal article; Peer reviewed, 2012)The products of the pyrolysis of four sesquiterpenes, β-caryophyllene, α-cedrene, longifolene and valencene, have been examined. Pyrolysis was carried out at 300, 400 and 500 °C, the products determined by GC–MS and then ... -
