The Cyclic Prefix of OFDM/DMT - An Analysis
We address the impact of a too short cyclic prefix on multicarrier systems such as orthogonal frequency division multiplexing (OFDM) and discrete multitone (DMT). The main result is that the intersymbol interference (ISI) and intercarrier interference (ICI) may be spectrally concentrated and analytical expressions showing this are given. A practical implication is, e.g., that the cyclic prefix in

Spindeln i klistret : Den kliniska praktikens betydelse för utveckling av yrkeskompetens som sjuksköterska: en etnografisk-fenomenografisk studie
The aim of the study was to investigate the role of clinical experience in the acquisition of professional competence during education and training in nursing. Competence is given a relational interpretation. The acquisition of professional competence is considered in terms both of the subject area involved and of cultural and organizational aspects specific to the nursing profession and to nursin

Time Dependent Density Functional Theory and Strongly Correlated Systems: Insight From Numerical Studies
We illustrate the potential of Time Dependent Density Functional Theory (TDDFT) for describing the nonequilibrium behavior of strongly correlated (lattice) models. Starting from an exact time-evolution of the many-body wavefunction, we determine, via reverse engineering, the exact exchange correlation (xc) potential $v_{xc}$ for small Hubbard chains of different lengths and electron fillings and e

The relation between implicit researcher-gender associations and perceptions of a research career
Coming to Terms – The Narrativity in Sigrid Combüchen's Tale Parsifal.
The frame story takes place in a dystopian Europe, possibly some kind of European Union around 2050 – in a state of conflicts and decay. The protagonists are a retired general, Piscator (cf. Fisher King) and a former journalist, Perle Vaus (cf. Perlesvaus/Perceval/Parsifal). She lost her home because of a new genderrelated law and stays homeless with others, covered by the Saxon bridge. Perle us
Aerosol Properties and Unattached Fraction of Radon Daughters Close to the Human Face
A humanoid dummy inside a well controlled radon exposure chamber (volume=20m3) was used to investigate the properties of an aerosol close to, and far away from the human face, respectively. Rn222 and a NaCl aerosol (geometric mean diameter=86 nm, concentration ( 5000 cm-3 was added to the room. The size distribution of the passive aerosol and the unattached fraction of the radon progeny were measu

Theoretical Studies of Spin-Dependent Quantum Phenomena in Semiconductor Nanostructures
The study of spin transport has emerged at the forefront of condensed matter physics during the last decade. Much of the interest has undoubtedly been sparked by the advent of the spintronics paradigm and the idea of creating novel electronic devices based on the spin degree of freedom of the carriers. However, a great deal of interest is due to the rich physics that emerges from the study of spin

When geophysics met geomechanics: Imaging of geomechanical properties and processes using elastic waves
Geophysics measurement techniques can be considered as non-destructive, remote methods to analyse the physical properties of geologic materials hidden at depth in the earth, within geotechnical structures or within laboratory test specimens. The objective of this paper is to highlight at least some of the potential to use geophysics methods to aid geomechanical investigations, both at the laborato

On inference in partially observed Markov models using sequential Monte Carlo methods
This thesis concerns estimation in partially observed continuous and discrete time Markov models and focus on both inference about the conditional distribution of the unobserved process as well as parameter inference for the dynamics of the unobserved process. Paper A concerns calibration of advanced stock price models, in particular the Bates and NIG-CIR models, using options data observed thro
