Ensemble averaged and single Particle Auger Lifetimes in Zincblende Structure Semiconductors
(Master thesis, 2013)In this master?s thesis, ensemble averaged and k-dependent Augerrecombination processes are studied using Monte Carlo integration. Effectsof introducing kp-overlap integrals, as opposed to constant overlap integrals, ... -
Pressure Fluctuations and Correlations in Steady State two Phase Flow in Porous Media
(Master thesis, 2013)This thesis investigates the burst size distribution and pressurecorrelation profiles of steady state two phase flow in porous mediaat various capillary numbers and viscosity ratios. A network modelis used to simulate ... -
Determination of the energy landscape among biological macromolecules: The mucin-alginate case
(Master thesis, 2013)Luminal epithelial surfaces of our body are covered by a secreted layer of mucus consisting chiefly of water (95%), high molecular weight polymeric glycoproteins known as mucins (3%), and other small molecules (2%). If ... -
Casimir friction between dense polarizable media
(Peer reviewed; Journal article, 2013)The present paper—a continuation of our recent series of papers on Casimir friction for a pair of particles at low relative particle velocity—extends the analysis, so as to include dense media. The situation becomes, in ... -
Singlet-triplet superconducting quantum magnetometer
(Journal article, 2013)Motivated by the recent experimental realization of a quantum interference transistor based on the superconducting proximity effect, we here demonstrate that the inclusion of a textured ferromagnet both strongly enhances ... -
Optimization in CT: Evaluation of dose saving potential in a thorax-abdomen/pelvis protocol using iterative reconstruction techniques
(Master thesis, 2013)The use of computed tomography (CT) has increased dramatically during the last two decades and contributes today to 80% of the estimated population dose caused by radiological examinations. Recent publications have shown ... -
The Chiral Phase Transition in QCD: Mean-Field Versus the Functional Renormalisation Group
(Master thesis, 2013)In this thesis we map out the phase diagram of the chiral phase transition of quantum chromodynamics (QCD) in the plane of temperature and quark chemical potential. We use the linear sigma model with quarks (LSMq) as a low ... -
Textbook images: How do they invite students into physics?
(Journal article; Peer reviewed, 2013)This paper presents a study of images in Norwegian physics textbooks for upper secondary school, and how they invite students into physics by means of visual communication. The concept of 'framing' is used to investigate ... -
Electric-field-induced structuring and rheological properties of kaolinite and halloysite
(Journal article, 2013)Electric-field-induced structuring of kaolinite and halloysite particles was studied in respect to their electrorheological (ER) response in silicone oil and in paraffin dispersions. The structural and morphological ... -
Graphene mode-locked Cr:ZnS laser with 44 fs pulse duration
(Chapter, 2013)The first Cr:ZnS laser mode-locked by graphene-based saturable absorber mirror generates the shortest reported so far mid-IR pulses of only 5.5 optical cycles (44 fs) at 2.35 μm with 139 nm spectral bandwidth. -
Technological Knowledge displayed in D&T classrooms: A video study of the realisation of design and technology education in Norwegian schools
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:184, Doctoral thesis, 2013) -
Mesospheric CO above Troll station, Antarctica observed by a ground based microwave radiometer
(Journal article; Peer reviewed, 2013)This paper presents mesospheric carbon monoxide (CO) data acquired by the ground-based microwave radiometer of the British Antarctic Survey (BAS radiometer) stationed at Troll station in Antarctica (72° S, 2.5° E, 1270 m ... -
Spin-Orbit-Induced Transport in Metals and Superconductors
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:112, Doctoral thesis, 2013)This thesis is devoted to the theoretical study of spin-orbit-induced transport in diffusive normal metals and superconductors. The spin-orbit interaction plays a vital role in the aspiring field of spintronics, which aims ... -
Variability of the Quasi Two-Day Wave in the Mesosphere
(Master thesis, 2013)The Quasi-Two-Day-Wave (QTDW) is examined through analysis of data given by the SKiYMET-radar at Dragvoll, Trondheim (63◦N,10◦E). Through spectral analysis the occurrence and generation mechanisms of the different wave ... -
Chaotic chirped-pulse oscillators
(Journal article; Peer reviewed, 2013)We present results of experimental investigation of the chaotic and quasi-periodic regime in the chirped-pulsed (dissipative soliton) Cr:ZnS and Cr:ZnSe mid-IR oscillators with significant third-order dispersion. The ... -
Particle Production in Gravitational Fields
(Master thesis, 2013)In this thesis, we discuss the phenomenon of particle production in gravitational fields. We present the general framework in flat Friedmann-Robertson-Walker spacetimes and apply it to an asymptotically static model in two ... -
Ultrasound radiation force transport of drugs in tumors
(Master thesis, 2013)Delivery of chemotherapeutic agents administered intravenously tosolid tumors tissue in optimal quantities is one of the challenges in theclinic. However, ultrasound improves the delivery of the chemothera-peutic agents ... -
Teaching with student response systems (SRS): teacher-centric aspects that can negatively affect students' experience of using SRS
(Journal article; Peer reviewed, 2013)In this article, we describe and discuss the most significant teacher-centric aspects of student response systems (SRS) that we have found to negatively affect students’ experience of using SRS in lecture settings. By doing ... -
