Hyperspectral near infrared imaging of untreated aspen and adaptation of an existing mould prediction model
(Master thesis, 2015-08-10)Wood as a building material is beneficial for the environment; it stores CO2 and saves CO2 emissions from other materials. Prediction models of mould growth are necessary to estimate the service life of wood. To make ... -
Hyperspectral photoluminescence imaging of silicon wafers and solar cells
(PhD Thesis;2018:59, Doctoral thesis, 2018)Hyperspectral photoluminescence imaging is a non-destructive characterization method used to study radiative defects in crystalline silicon wafers and solar cells. It provides both spatial distribution and spectral response ... -
Hyperspectral photoluminescence of thermal donors in two Czochralski crystals pulled at different velocities
(Master thesis, 2019)This study has shown that hyperspectral photoluminescence (HSPL) imaging may be used for connecting defect-related luminescence (DRL) signals to electrically active oxygen clusters of thermal donors (TDs). Thus, by using ... -
Hyperspectral photoluminescence scans of mc- Si wafers analysed through Multivariate Curve Resolution (MCR)
(Master thesis, 2014-08-26)Characterisation of defects in solar cell material is one step towards higher energy conversion efficiency of solar cells. The method used in this study allows detection across the wafer of defects causing radiative SRH ... -
Identification of biomarkers from Radiomics of brain scans for prediction of major depression using Repeated Elastic Net Technique
(Master thesis, 2022)The application of machine learning in the field of medicine is expanding on an almost daily basis. Data from the healthcare industry typically have high dimensionality but a limited sample size. The learning process can ... -
Identification of Coronavirus Through CT-scan Images Using Supervised and Semi-supervised Learning
(Master thesis, 2023)* This study if based on the exploration of four different supervised deep learning models namely DenseNet201, ResNet50, CNN_model_1 (five blocks) and CNN_model_2 (seven blocks) for the identification of COVID-19 through ... -
Identification of efficient and affordable technologies for sustainable production of biodiesel from various bio-resources
(PhD Thesis;2019:88, Doctoral thesis, 2019)Population growth and a significant improvement in living standards in most parts of the world has resulted in an increasing energy demand. Fossil fuels are used for most of the world’s energy demands. However, fossil fuels ... -
Identifying Materials with Low Lattice Thermal Conductivity Using Machine Learning and Computational Modeling
(Phd Thesis;2023:13, Doctoral thesis, 2023)Lattice thermal conductivity is a key materials property in applications related to thermal functionality, such as thermal barrier coatings, thermal conductors in microelectronics, and solid-state waste-heat recovery ... -
Idrettsanlegg og det feminine kjønn : en empirisk og prosjekteringsoppgave
(Master thesis, 2013-10-28)Statistikken viser at jenter og kvinner deltar i den organiserte idretten i mindre grad enn det maskuline kjønn. Oppgaven har som hensikt å finne årsaken til dette og komme med et forslag til hvordan man kan utforme et ... -
IFC og energisimulering : hva kreves av eksporten og hva følger med?
(Master thesis, 2012-08-31)Hensikten med oppgaven var å undersøke hva som følger med i eksporten av en IFC-modell til energianalyseverktøy. For å undersøke dette ble det tatt i bruk ArchiCAD som modelleringsprogram, VIP-Energy og SIMIEN som ... -
