1. Embedded digital filter design and implementation
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : 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. LÄS MER
2. Phase Unwrapping MRI Flow Measurements
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3Sammanfattning : 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. LÄS MER
3. Reconstruction of Accelerated Cardiovascular MRI data
Master-uppsats, Linköpings universitet/Statistik och maskininlärningSammanfattning : Magnetic resonance imaging (MRI), is a noninvasive medical imaging testing techniquewhich is used to produce detailed images of internal structure of the human body, includingbones, muscles, organs, and blood vessels. MRI scanners use large magnets and radiowaves to create images of the body. LÄS MER
4. Automated Inference of ACSL Contracts for Programs with Heaps
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
5. Procedural Natural Texture Generation on a Global Scale
Master-uppsats, Linköpings universitet/InformationskodningSammanfattning : 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.
