Density Functionals for Dynamic Linear Response in Finite Systems

This dissertation investigates a new method for obtaining excited-state properties of finite, many-electron systems such as atoms, molecules and nano-systems. The method combines the merits of many-body perturbation theory and time-dependent perturbation theory and yields approximate density response functions which preserve basic physical conservation laws. Furthermore, advanced density functiona

Sensitivity of tissue differentiation and bone healing predictions to tissue properties

Computational models are employed as tools to investigate possible mechano-regulation pathways for tissue differentiation and bone healing. However, current models do not account for the uncertainty in input parameters, and often include assumptions about parameter values that are not yet established. The aim was to clarify the importance of the assumed tissue material properties in a computationa

Network formation of graphene oxide in poly(3-hydroxybutyrate) nanocomposites

Polyhydroxy alkanoates (PHAs) are bio-based, biodegradable and sustainable polyesters that are produced naturally by different types of bacteria. Recently, interest in these materials has gained strongly to broaden their application range, by modifying their properties through blending and/or using nanofillers. In this contribution we will focus on the modification of Poly[3-hydroxybutyrate] (PHB)

Gayikon, flickidol, livsdyrkare

Jag behandlar den svenske popartisten Håkan Hellström, och analyserar hans persona och poplyrik med avseende på genuskonstruktioner. Jag fokuserar bland annat på den reception som dels har beskrivit Hellström som en gayikon, dels den som sett honom som en flickidol. Jag menar att båda dessa roller gestaltas i Hellströms konstnärliga verksamhet, och att hans karriär, persona och konstnärliga verksa

Images of Reality - Interacton space analysis and large-scale design in open office landscape environments

This chapter explores communication patterns and media choices among employees, as well as their connection with the ongoing changes in workplace design. It presents a multiple case study of communication and co-ordination in open landscape office environments. The study was carried out in three different organisations; an advertising firm, a manufacturing business, and an IT development office. I

SOFC Cathode Design Optimization using the Finite Element Method

Solid oxide fuel cells (SOFCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. A 3D model is developed based on the finite element method (FEM), using COMSOL Multiphysics, of a single SOFC operating at an intermediate temperature range. Ion, electron, heat, gas-
