Surface studies of palladium based membranes and model systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:64, Doctoral thesis, 2009)The work of this thesis can be divided in to parts, one is based on the Pd/Ag alloy membranes and the other is about the model systems. It is well known that, Pd is a potential candidate membrane material, due to both its ... -
Survival Analysis using Integrated Nested Laplace Approximations: A Case Study of House Sparrows from Aldra
(Master thesis, 2011)The animal model is a generalized linear mixed model (GLMM) often used in evolutionary biology and animal breeding. Integrated Nested Laplace Approximation (INLA) is a quite new methodology for making fast non-sampling ... -
Svak Verdi - Et studie i egenskaper ved, og observasjoner av, svake verdier
(Master thesis, 2015)Prosessen for måling av svak verdi er blitt gjennomgått, debatten rundt betydningen av den svake verdien og dens rolle i forklaringen av kjente paradokser har blitt belyst. Det har blitt gjennomgått en modell for, og et ... -
Svakt vekselvirkende Bosegasser ved lave temperaturer: Et studium av Bose-Einstein kondensasjon ved bruk av effektiv feltteori.
(Master thesis, 2009)I denne masteroppgaven tar vi for oss svakt vekselvirkende Bosegasser, og vi skal se at et slik system har en annen oppførsel enn en ideell gass selv ved temperatur T=0. I tillegg skal vi finne en effektiv feltteori for ... -
Swelling Dynamics of a DNA-Polymer Hybrid Hydrogel Prepared Using Polyethylene Glycol as a Porogen
(Peer reviewed; Journal article, 2015)DNA-polyacrylamide hybrid hydrogels designed with covalent and double-stranded (dsDNA) crosslinks respond to specific single-stranded DNA (ssDNA) probes by adapting new equilibrium swelling volume. The ssDNA probes need ... -
Swelling of a hemi-ellipsoidal ionic hydrogel for determination of material properties of deposited thin polymer films: an inverse finite element approach
(Journal article; Peer reviewed, 2013)Selective deposition of polymers at the surface of an ionic hydrogel is conventionally used to tailor properties of the composite material for application in for instance drug release and cell encapsulation. Here we describe ... -
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’ ... -
Switchable Ultra-Wideband All-Optical Quantum Dot Reflective Semiconductor Optical Amplifier
(Peer reviewed; Journal article, 2023)A comprehensive study has been conducted on ultra-broadband optically pumped quantum dot (QD) reflective semiconductor optical amplifiers (QD-RSOAs). Furthermore, little work has been done on broadband QD-RSOAs with an ... -
Symmetry and mass degeneration in multi-Higgs-doublet models
(Journal article; Peer reviewed, 2011)We investigate possible symmetry properties of the scalar sector of Multi-Higgs-Doublet Models, and, to some extent, the generalization of such models to gauge groups other than SU(2) L × U(1) Y . In models with C (charge ... -
Symmetry Breaking in ordinary and supersymmetric Models of Quantum Field Theory
(Master thesis, 2012)This thesis will consider two different theories, and apply variational techniquesto each, in order to investigate their true ground states and the possibility ofsymmetry breaking.A scalar field theory is modified by ... -

Synchrotron Study of Cement Hydration: Towards Computed Tomography Analysis of Interfacial Transition Zone
(Journal article; Peer reviewed, 2017)The quality of bonding between cement and steel in wells is controlled by the interfacial transition zone (ITZ). Micro-computed X-ray tomography (μ-CT) imaging with synchrotron radiation was used in the current paper to ... -
Synchrotron X-ray Characterization of Atomic and Nanoscale Structures in Aperiodic Materials from Ambient to Extreme Conditions — Synergic Collaboration with Large-scale Computer Simulations
(World Scientific Series in Nanoscience and Nanotechnology;, Chapter, 2021)With the advent of the third generation of synchrotron sources and the development of light source techniques, the high energy (E > 50 keV) X-ray scattering technique has become feasible, leading to new approaches for ... -
Synergistic Computational-Experimental Discovery of Highly Selective PtCu Nanocluster Catalysts for Acetylene Semihydrogenation
(Journal article; Peer reviewed, 2019)Semihydrogenation of acetylene (SHA) in an ethylene-rich stream is an important process for polymer industries. Presently, Pd-based catalysts have demonstrated good acetylene conversion (XC2H2), however, at the expense of ... -
