1. 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
2. Comparison of In Vivo Intramuscular Fat Quantification Techniques in MRI
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : People with cerebral palsy (CP) may develop muscle contractures, which are defined as a loss of joint range due to an increase in passive muscle stiffness [1]. Computer models suggest that intramuscular fat can increase muscle stiffness [2]. LÄS MER
3. FMCW mmWave Radar for Detection of Pulse, Breathing and Fall within Home Care
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Countless of elderly people fall and get hurt within their homes, worldwide, every year, and as they can not always reach out for help themselves, they end up helplessly waiting for someone to notice what has occurred. Throughout this work, it is investigated if remote sensing of the mmWave FMCW radar IWR6843AOPEVM can be adopted to detect the incident of falls, and also detect the vital signs of the human subject.

4. Depth Data Processing and 3D Reconstruction Using the Kinect v2
Master-uppsats, Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakultetenSammanfattning : The Kinect v2 is a RGB-D sensor manufactured as a gesture interaction tool for the entertainment console XBOX One. In this thesis we will use it to perform 3D reconstruction and investigate its ability to measure depth. LÄS MER
5. Surface Roughness Measurment: Multi-bandFrequency Shift Interferometer based onPolarization Measurement
Magister-uppsats, Högskolan i Halmstad/Tillämpad matematik och fysik (MPE-lab)Sammanfattning : Optical measurement techniques have been gaining ground for their vast applications in industry and scientific purposes. These techniques are beneficial comparing to the mechanical methods. Non-intrusive, robust, high accuracy and small measurement volume are some of the advantages of the optical metrology. However, these approaches are expensive. LÄS MER
