1. Color halftoning methods for screen printing and special effect pigments : Reproducing iridescent colors
University essay from Linköpings universitet/Institutionen för teknik och naturvetenskapAbstract : Iridescence is the property that makes colors vary by angle of observation. Technology has made it possible to print with ink that has this anisotropic property. The ink that is used contains microparticles and therefore only specific printing methods can be used, for example screen printing. READ MORE

2. Optimal Q-Space Sampling Scheme : Using Gaussian Process Regression and Mutual Information
University essay from Uppsala universitet/Avdelningen för systemteknikAbstract : Diffusion spectrum imaging is a type of diffusion magnetic resonance imaging, capable of capturing very complex tissue structures, but requiring a very large amount of samples in q-space and therefore time. The purpose of this project was to create and evaluate a new sampling scheme in q-space for diffusion MRI, trying to recreate the ensemble averaged propagator (EAP) with fewer samples without significant loss of quality.

4. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects
University essay from Lunds universitet/Matematisk fysikAbstract : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. READ MORE
