As modern production moves towards higher efficiency and cost effectiveness, machining difficult-to-cut materials becomes an increasing challenge. Quickly and reliably characterizing the properties of materials could significantly improve the performance of machining processes in terms of their efficiency and production cost. This dissertation deals with the methodology for characterizing the micr
We consider a multiple input multiple output (MIMO) system wherein channel correlation as well as noisy channel estimation are both taken into account. For a given block fading duration, pilot-assisted channel estimation is carried out with the aid of a minimum mean square error estimator. The pilot sequences and data are jointly optimized to maximize the ergodic capacity while fulfilling a total
Projektet NOA finansierades av Europeiska socialfonden (Växtkraft, Mål 3) och vände sig till långtidssjukskrivna vid Försäkringskassan i Malmö mellan åren 2005-2007. Utvärderingen av projektet har en formativ och en summativ del och bygger på intervjuer med kursdeltagare, projektledare, arbetspsykologer och outplacementkonsulter. Deltagarna beskriv utbytet av projektet på olika sätt. En del betona
Using exact dispersion relations for electromagnetic wave propagation in layered, periodic media, consisting of two phases, we derive explicit asymptotic solutions for small wavenumbers. These solutions are compared to the numerical solutions of the exact dispersion relations, and applications to homogenization problems are discussed. The results can be used as test cases for homogenization techni
A search for narrow baryonic resonances decaying into Ξ-π- or Ξ-π+ and their antiparticles is carried out with the H1 detector using deep inelastic scattering events at HERA in the range of negative photon four-momentum transfer squared 2 < Q2 < 100 GeV2. No signal is observed for a new baryonic state in the mass range 1600–2300 MeV in either the doubly charged or the neutral decay channels. The k
A method for determining transition matrices for inhomogeneous dielectric shells is presented. The source can be either inside or outside the shell. The method is based upon expansions of the electric and magnetic fields in vector spherical harmonics. The expansion coefficients in the shell satisfy a system of linear ordinary differential equations in the radial direction. The expansion coefficien
Reflektioner i text och bild kring ett tioårigt samarbetsprojekt mellan konstnärerna Inger Bergström, Elizabet Christiansson, Tarika Lennerbjörk och Maria Wahlgren. Artikeln fokuserar särskilt på konstens och forskningens hantverk utifrån utställningen Researcher in Residence på Kunstindustrimuseum 2005.
Moraxella catarrhalisis a human respiratory pathogen that causes acute otitis media in children and is associated with exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD). The first step inM. catarrhaliscolonization is adherence to the mucosa, epithelial cells, and extracellular matrix (ECM). The objective of this study was to evaluate the role ofM. catarrhalisint
III-V nanoscale devices were monolithically integrated on silicon-on-insulator (SOI) substrates by template-assisted selective epitaxy (TASE) using metal organic chemical vapor deposition. Single crystal III-V (InAs, InGaAs, GaAs) nanostructures, such as nanowires, nanostructures containing constrictions, and cross junctions, as well as 3D stacked nanowires were directly obtained by epitaxial fill
