The role of the QBO in the inter-hemispheric coupling of summer mesospheric temperatures
(Journal article; Peer reviewed, 2011)Inter-hemispheric coupling between the polar summer mesosphere and planetary-wave activity in the extratropical winter stratosphere has recently been inferred using Polar Mesospheric Cloud (PMC) properties as a proxy for ... -
The propagation and energy losses of ultra high energy cosmic rays
(Master thesis, 2011)This project investigates the propagation of ultra-high energy cosmic raynuclei and protons. A simulation of the propagation subjecting the particlesto energy losses due to cosmological redshift as well as interactions ... -
Quantitative characterization of articular cartilage using Mueller matrix imaging and multiphoton microscopy
(Journal article; Peer reviewed, 2011)The collagen meshwork in articular cartilage of chicken knee is characterized using Mueller matrix imaging and multiphoton microscopy. Direction and degree of dispersion of the collagen fibers in the superficial layer are ... -
Broadband method for group velocity dispersion measurements in the mid-infrared
(Journal article; Peer reviewed, 2011)A setup for broadband measurements of dispersion parameter in optical fibers based on the Mach–Zehnder interferometer is developed. Tm-doped fiber pumped at 1.61 μm was used as a source of broadband emission, that allowed ... -
Characterization of electrical activity and lifetime in compensated multicrystalline silicon
(Master thesis, 2011)This master's thesis concerns the electrical activity and lifetime in compensated multicrystalline silicon wafers used for solar cell production.Resistivity profiles across grain boundaries have been obtained by a Four ... -
Quantitative studies of clustering and precipitation in Al-Mg-Si(-Cu) alloys
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:212, Doctoral thesis, 2011)In the present work, the clustering and precipitation reactions in age hardenable Al-Mg- Si(-Cu) (6xxx) alloys have been studied by atom probe tomography (APT), transmission electron microscopy (TEM) related methods and ... -
Modellering av Termisk Stråling for Bruk i Brannsimuleringer.: En teoretisk analyse og studie av noen aspekter
(Master thesis, 2012)Numerisk løsning av termisk varmetransport spiller en viktig rolle i simuleringer av brann og andre systemer med høy temperatur, som er et sentralt anvendelsesområde for multifysikk-programpakken Brilliant som blir utviklet ... -
On functional imaging and treatment planning for biologically adapted radiotherapy
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:65, Doctoral thesis, 2012)Tumours show large variations in response to radiotherapy, both across tumour types and within individual tumours. One way to counteract radioresistance is to increase the radiation dose to resistant regions by so-called ... -
Development of 3-D Quantitative Analysis of Multi-Photon Microscopy Images
(Master thesis, 2012)Motivation: Cartilage is a robust but flexible connective tissue found in most joints of the body. The collagen fibres present in the extracellular matrix of cartilage contribute to its tensile strength and stiffness. The ... -
Spin-Transfer and Exchange Torques in Ferromagnetic Superconductors
(Journal article; Peer reviewed, 2012)We consider how superconducting correlations influence spin-transfer torques in ferromagnetic superconductors. It is demonstrated that there is a novel torque arising from particle-hole interference that depends on the ... -
Development and testing of a Linnik Interference Microscope for Sub-surface Inspection of Silicon during moving Indentation
(Master thesis, 2012)Fixed-abrasive diamond wire sawing is a promising technique for reduction of costs related to sawing of silicon wafers for solar cells. The microscopic mechanisms of material removal in the process are however not fully ... -
Thermal resummation in scalar theories: Chiral transition and magnetic effects in the quark-meson model

Swelling transition of a clay induced by heating
(Journal article; Peer reviewed, 2012)Clays are of paramount importance for soil stability, but also in applications ranging from oil recovery to composites and hydrogels. Generically, clays are divided into two subclasses: macroscopically swelling, ‘active’ ... -
X-ray Studies of Capture, Storage and Release of CO2
(Master thesis, 2012)We show experimentally that CO2 intercalates into the interlayer spaceof the synthetic smectite clay Li-fluorohectorite (LiFh). The intercalationoccurs for a range of conditions in terms of pressure (5 bar to 20 bar) ... -
Spectral Broadening of mid-IR Femtosecond Pulses in Highly Germanium Doped Fiber
(Chapter, 2012)We demonstrate significant spectral broadening of femtosecond mid-IR pulses directly from the oscillator in a simple step-index single-mode highly Ge-doped fiber at only 150 pJ pulse energies in the spectral window around 2.38 µm. -
Local Resistivity Measurement on Multicrystalline Silicon
