1. 1. Phase Unwrapping MRI Flow Measurements

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Mio Liljeblad; [2023]
   Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

   Abstract : 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

3. 2. Estimating Relative Position and Orientation Based on UWB-IMU Fusion for Fixed Wing UAVs

   University essay from Linköpings universitet/Reglerteknik

   Author : Daniel Sandvall; Eric Sevonius; [2023]
   Keywords : UWB; Relative positioning; Sensor fusion; UAV; Formation flight; Fixed wing; Relative localization; EKF; FGO;

   Abstract : In recent years, the interest in flying multiple Unmanned Aerial Vehicles (UAVs) in formation has increased. One challenging aspect of achieving this is the relative positioning within the swarm. READ MORE

4. 3. Feature-Aware Point Transformer for Point Cloud Alignment Classification : Pose your pose to FACT

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Ludvig Dillén; [2023]
   Keywords : point cloud alignment; point cloud alignment classification; alignment validation; point cloud; map validation; map quality; misalignment recognition; alignment quality; point transformer; Sinkhorn divergence; differential entropy; point cloud co-visibility; point cloud visibility; SLAM; point cloud registration; point cloud density;

   Abstract : As the demand for 3D maps from LIDAR scanners increases, delivering high-quality maps becomes critical. One way to ensure the quality of such maps is through point cloud alignment classification, which aims to classify the alignment error between two registered point clouds. READ MORE

5. 4. Mission Planning for the in-orbit Lunar calibrations of the MicroCarb instrument

   University essay from KTH/Rymdteknik

   Author : Erwan Caffier; [2021]
   Keywords : Phase angle; radiance; Moon; carbon monitoring; flight dynamics simulation; mission planning; Fasvinkel; radians; Månen; koldioxidövervakning; flygdynamik simulering; rymduppdragsplanering;

   Abstract : In-orbit calibrations of space instruments are often necessary to ensure the accuracy of the measurements. The Moon provides a target with very predictable characteristics. READ MORE

6. 5. Development of an exercise machine for enhanced eccentric training of the muscles : A study of sensors and system performance

   University essay from KTH/Mekatronik

   Author : Natalija Zivanovic; [2020]
   Keywords : Sensor resolution; sample time; smart exercise machine; system performance; incremental encoder; eccentric training; Sensorupplösning; samplingstid; smart träningsmaskin; systemprestanda; inkrementell pulsgivare; excentrisk träning;

   Abstract : Currently, there are various training machines that can support training of the muscles while the muscles are lengthened, also known as eccentric training. Training machines that are widely used to train the muscles eccentrically utilize a flywheel to generate load to the user. READ MORE
