Quantifying the influence of the stratosphere on the mesosphere and lower thermasphere
(Doctoral thesis at NTNU;2015:22, Doctoral thesis, 2015)In this thesis, the influence of the major modes of stratospheric variability - the seasonal cycle and sudden stratospheric warmings (SSWs) in the extratropics, and the quasi-biennial oscillation (QBO) in the equatorial ... -
Quantitative (S)TEM analysis of intermediate band solar cell materials
(Master thesis, 2011)In this thesis the strain properties of two InAs/GaAs quantum dot intermediate band solar cell materials have been explored. Both samples were thin films grown on a (100) GaAs substrate. The quantum dot material was InAs, ... -
Quantitative 3-D colocalization analysis as a tool to study the intracellular trafficking and dissociation of pDNA-chitosan polyplexes
(Journal article; Peer reviewed, 2012)Multichannel microscopy is frequently used to study intermolecular interactions and spatial relationships between biomolecules and organelles or vesicles in cells. Based on multichannel images, quantitative colocalization ... -
Quantitative 3D Imaging and Metrology Using Coherent X-ray Scattering
(Doctoral theses at NTNU;2017:300, Doctoral thesis, 2017)This thesis has focused on exploring methods of using coherent X-ray scattering at synchrotron sources. New imaging techniques using coherent X-ray scattering have been investigated, and it has been discussed how limitations ... -
Quantitative 3D X-ray Imaging of Densification, Delamination and Fracture in a Micro-Composite under Compression
(Journal article; Peer reviewed, 2015)Phase-contrast three-dimensional tomograms showing in unprecedented detail the mechanical response of a micro-composite subjected to a mechanical compression test are reported. The X-ray ptychography images reveal the ... -
Quantitative analysis of tumor heterogeneity based on magnetic resonance images
(Master thesis, 2019)Background: Solid tumors are commonly heterogeneous because they consist of cancer cells with different aggressiveness. In quantitative cancer imaging, such as magnetic resonance imaging (MRI), the heterogeneity will not ... -
Quantitative Analysis of Vascular Function in Malignant Tumours
(Master thesis, 2018)Sammendrag: Formålet med denne avhandlingen var å undersøke den vaskulære funksjonen i ondartede svulster ved hjelp av histologiske og immunohistokjemiske (IHC) snitt og se etter assosiasjoner med magnetresonanstomografi ... -
Quantitative analysis of {100} Al plate/lath- and Al rod-shaped precipitates in an aged Al-Cu-Mg-Si alloy using TEM
(Peer reviewed; Journal article, 2021)Precipitate parameters, such as length, diameter and thickness of rationally oriented {100}Al plate/lath-shaped and Al rod-shaped precipitates in an age-hardenable Al-Cu-MgSi alloy have been examined quantitatively. An ... -
Quantitative and qualitative consequences of reduced pollen loads in a mixed-mating plant
(Journal article; Peer reviewed, 2019)Greater pollination intensity can enhance maternal plant fitness by increasing seed set and seed quality as a result of more intense pollen competition or enhanced genetic sampling. We tested experimentally these effects ... -

Quantitative assessment of observed versus predicted responses to selection
(Peer reviewed; Journal article, 2021)Although artificial-selection experiments seem well suited to testing our ability to predict evolution, the correspondence between predicted and observed responses is often ambiguous due to the lack of uncertainty estimates. ... -
Quantitative atomic force microscopy and light microscopy of hydrogels and cells
(Doctoral theses at NTNU;2016:343, Doctoral thesis, 2016)Quantitative biology is an interdisciplinary subject that combines biology, mathematics and physics. Intimate collaboration on a global scale between these disciplines results in a wide variety of tools and innovation in ... -
Quantitative Characterization of Absorbents for CO2 Capture
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:221, Doctoral thesis, 2013)Global warming has become one of the world’s most important challenges over the last decades and carbon dioxide (CO2) emissions are determined to be a major contributor. Various carbon dioxide capture and storage (CCS) ... -
Quantitative characterization of articular cartilage using Mueller matrix imaging and multiphoton microscopy
