1. Numerical Methods for Aerodynamic Shape Optimization
Sammanfattning : Gradient-based aerodynamic shape optimization, based on Computational Fluid Dynamics analysis of the flow, is a method that can automatically improve designs of aircraft components. The prospect is to reduce a cost function that reflects aerodynamic performances. LÄS MER
2. Reportaget som kom av sig : en analys av reportaget som textform utifrån produktionsperspektivet och sändarrollen med betoning på reporterns personliga tonfall : en undersökning av reportaget i några landsortstidningar 1960-1985
Sammanfattning : Reportage is a generally accepted, yet poorly defined genre in Swedish newspaperterminology. It is usually associated with journalistic texts that are produced outside theroutines of daily news coverage; reportage features also have a more personal tone thanstandard news texts in that the reporter imparts his or her personal observations andperceptions of the scene in question.

3. Lipid Nanotube Networks: Shape Transitions and Insights into the Dynamics of Self-Organization
Sammanfattning : Nanotube-vesicle networks (NVNs) are simplified models of cell membrane tubular systems which are dynamic transportation routs for molecular cargoes in biological cells. The presented work describes dynamic properties of NVNs such as self-organization, shape and topology transformations; moreover, specific geometric properties of the networks are used for controlling enzymatic reactions.

4. Receptivity of Boundary-Layer Flows over Flat and Curved Walls
Sammanfattning : Direct numerical simulations of the receptivity and instability of boundary layers on flat and curved surfaces are herein reported. Various flow models are considered with the aim to capture aspects of flows over straight and swept wings such as wall curvature, pressure variations, leading-edge effects, streamline curvature and crossflow.

5. Tunable Magnetic Properties of Transition Metal Compounds
Sammanfattning : The magnetic properties of transition metal compounds have been studied using SQUID-magnetometry, magnetic force microscopy and Lorentz transmission electron microscopy. New magnetic materials have been found and their magnetic properties have been determined. How the magnetic properties of a material can be changed through e.g. LÄS MER
