A Study of Different Platforms and Sensory Systems for Wheat Field Trials
Bleken, Eivind Aleksander (Master thesis, 2017)In the field of agriculture several technical advances have been implemented to meet the growing demand with regards to food supply. As an indicator for grain yield in wheat different indices have been tested and evaluated ... -
Beregning av biomasse ved hjelp av multispektral laser
Ceballos, Kristoffer Mauricio Valderrama (Master thesis, 2018)I dette prosjektet her jeg beregnet biomasse til trær fra felt arbeid og fra laserdata. Gjennom dette prosjektet har jeg belyst temaer som er relevant for estimering av biomasse, og hvilke metoder og teknikker som er ... -
Brick wall analysis by photogrammetry and image processing techniques
Johnsen, Espen (Master thesis, 2018)Deterioration of brick wall buildings can be seen as an effect from years of exposure to wind and weather. For example, through repeated freeze-thaw cycles, structural damage of the bricks might occur. In this thesis a ... -
Controlled infrared heating of an artic meadow: challenge in the vegetation establishment stage
Moni, Christophe; Silvennoinen, Hanna Marika; Kimball, Bruce A.; Fjelldal, Erling; Brenden, Marius; Burud, Ingunn; Flø, Andreas Svarstad; Rasse, Daniel (Journal article; Peer reviewed, 2019)Background: Global warming is going to affect both agricultural production and carbon storage in soil worldwide. Given the complexity of the soil-plant-atmosphere continuum, in situ experiments of climate warming are ... -
Defect related radiative recombination in mono-like crystalline silicon wafers
Bergan, Simen (Master thesis, 2016-08-31)The aim of this work was to investigate defect related luminescence emission in four mono-like silicon wafers. The seed-assisted silicon ingot is built by six Czochralski silicon slabs, with nine seed junctions. The ... -
Defects in multicrystalline Si wafers studied by spectral photoluminescence imaging, combined with EBSD and dislocation mapping
Mehl, Torbjørn; Di Sabatino Lundberg, Marisa; Adamczyk, Krzysztof; Burud, Ingunn; Olsen, Espen (Journal article; Peer reviewed, 2016) -
Estimation of phosphorus-based flame retardant in wood by hyperspectral imaging—a new method
Stefansson, Petter; Burud, Ingunn; Thiis, Thomas Kringlebotn; Gobakken, Lone; Larnøy, Erik (Journal article; Peer reviewed, 2018)It is recognised that flame retardant chemicals degrade and leach out of flame-protected wood claddings when exposed to natural weathering. However, the ability to survey the current state of a flame retardant treatment ... -
Exploring robots and UAVs as phenotyping tools in plant breeding
Burud, Ingunn; Lange, Gunnar; Lillemo, Morten; Bleken, Eivind; Grimstad, Lars; From, Pål Johan (Journal article; Peer reviewed, 2017) -
Hyperspectral imaging as a tool for characterization of multicrystalline silicon wafers
Flø, Andreas Svarstad (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. ... -
Hyperspectral imaging as a tool to study solar induced photoluminescence from PV modules
Høiaas, Ingeborg Eriksdatter (Master thesis, 2019)The installedsolarphotovoltaic(PV) capacity in the world is increasing and solar PV is becoming a bigger part of the energy mix. Reviewed literature on PV field performance show an average degradation rate of 0.8%/year, ... -
