1. Embedded digital filter design and implementation
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer. READ MORE

2. Phase Unwrapping MRI Flow Measurements
University essay from Uppsala universitet/Avdelningen Vi3Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

4. Automated Inference of ACSL Contracts for Programs with Heaps
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Contract inference consists in automatically computing contracts that formally describe the behaviour of program functions. Contracts are used in deductive verification, which is a method for verifying whether a system behaves according to a provided specification. The Saida plugin in Frama-C is a contract inference tool for C code. READ MORE

5. Procedural Natural Texture Generation on a Global Scale
University essay from Linköpings universitet/InformationskodningAbstract : This Master’s thesis investigates the application of dynamically generated procedural terrain textures for texturing 3D representations of the Earth’s surface. The study explores techniques to overcome limitations of the currently most common method – projecting satellite imagery onto the mesh – such as insufficient resolution for close-up views and challenges in accommodating external lighting models.
