(PhD Thesis;2014:21, Doctoral thesis, 2014)This thesis describes the development of a method for characterization of multicrystalline silicon wafers based on hyperspectral imaging. The aim has been to show the distribution of radiative defects in silicon wafers. ... -
Field measurements and numerical simulations of snow transport and deposition around structures and into ventilation intakes
(PhD thesis;2014:66, Doctoral thesis, 2014)This work is concerned with field experiments and measurements, and numerical simulations of aeolian snow transport, especially the snow deposition on structures and around obstacles. The research work is interested in ... -
Optimisation of the coagulation process to improve plant availability of phosphorus in wastewater sludge
(PhD Thesis;2016:61, Doctoral thesis, 2016)Coagulation is used for the removal of colloids, particles and phosphates in wastewater treatment. The efficiency and economics of chemical coagulation, one of the most robust wastewater treatment processes, is critically ... -
The environmental life cycle assessment of selected 1st through 3rd generation biofuels within the context of sustainable development
(PhD Thesis;2016:38, Doctoral thesis, 2016)Biofuels, at all stages of technological development, exist all around us; primarily the result of society’s ambition to mitigate climate change associated with the transport sector. Parallel to this development has been ... -
Heterogeneous catalytic conversion of non-edible lipid biomass to biochemicals
(PhD Thesis;2016:84, Doctoral thesis, 2016)The use of fuel increases consistently given the high demand for energy. This demand is mostly met by fossil fuels. Considering the uncertainties connected to fossil fuel reserves and the related natural effects of their ... -
Enhancement of coagulant dosing control in water and wastewater treatment processes
(PhD Thesis;2016:62, Doctoral thesis, 2016)Chemical coagulation is one of the most important treatment processes in wastewater treatment and drinking water treatment. Defining the optimal coagulant dosage is a vital operation that decides the treatment efficiency ... -
Investigation of torrefaction and addition of alternative raw materials in biomass pelleting
(PhD Thesis;2016:01, Doctoral thesis, 2016)The interest in renewable energy sources is growing continuously owing to climate change and the limited amount of fossil fuels. Biomass is the most popular renewable energy source, and it will continue to play a key ... -
Developing offshore floating wind turbines : the Tension-Leg-Buoy design
(PhD Thesis;2016:22, Doctoral thesis, 2016-04-07)A 5 MW Tension-Leg-Buoy (TLB) concept has been optimized and developed. The design is based on the MIT Double Taut Leg, initially proposed by Professor Sclavounos of MIT in 2005. Six variants have been tested, in two wave ... -
Open inquiry in science classrooms: exploring and developing teachers' practices in upper secondary school
(PhD Thesis;2014:77, Doctoral thesis, 2016-06-09)The study was part of the research project StudentResearch (2007-2010), with the goal that students were to become knowledge builders in practices that have some common traits with scientific inquiry. The project was ... -
Methods of functional analysis in homogenized neural field theory
(PhD Thesis;2016:66, Doctoral thesis, 2016-11-24)One of the major challenges in neurobiology remains understanding the relationship between complex neural network dynamics underlying spatially structured activity states and the corresponding neural circuitry for which ... -
Detecting ideas in online communities : utilizing machine learning and text mining for finding ideas in online communities
(PhD Thesis;2017:18, Doctoral thesis, 2017)Online communities serve as a gathering point for dedicated product users and consumers who discuss all imaginable topics. Scholars have argued that this discussion can lead to new ideas useful for firms. That is, if the ... -
Geodetic observations and modeling of gravity field, sea level, and ocean dynamics in the Norwegian coastal zone
(Phd Thesis;2017:24, Doctoral thesis, 2017)Geodesy can contribute to a quantitative understanding of ocean circulation variability at northern high latitudes, which is crucial to environmental and climate-related studies. Coastal ocean dynamics has gained recent ... -
Sustainable planning to reduce urban flooding : an interdisciplinary approach
(PhD Thesis;2017:59, Doctoral thesis, 2017)Statistics show that there is a global trend of increased frequency of urban flooding. Floods can be caused by rising rivers (fluvial) and heavy rain (pluvial). The work presented here has been restricted to the most ... -
Quantitative microbial rsk assessment and water quality modelling : on drinking water sources, recreational and recycled waters
