  1. 1. Server-side factor graph optimization for on-manifold pre-integration in IoT sensors

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Samuel Gradén; [2023]
    Keywords : Edge computing; IoT; optimization; tracking; drone;

    Abstract : State and specifically location estimation is a core concept in automation and is a well-researched field. One such estimation technique is Moving Horizon Estimation (MHE). In this thesis, the MHE variant single-shooting estimation will estimate the location and velocity of a moving object. READ MORE

  3. 2. Local traversability assessment in an unmanned ground vehicle : An analysis of mobility on the UGV Husky

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kidus Y. Getahun; [2023]
    Keywords : UGV; Husky; Robotics Operating System; Traversability Estimation; Vehicle Dynamics; Elevation Mapping; UGV; Husky; Framkomlighets Bedömning; Fordonsdynamik;

    Abstract : This thesis project aims to learn and understand more about implementing a path planner to the unmanned ground vehicle (UGV), UGV Husky, specifically its traversability algorithm, and investigate how it could be further improved. A surrounding grid is generated around the UGV where each cell contains information connected to its traversability. READ MORE

  4. 3. 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

  5. 4. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Author : Nick Bergmans; [2023]
    Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Abstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE

  6. 5. Airspeed estimation of aircraft using two different models and nonlinear observers

    University essay from Linköpings universitet/Fordonssystem

    Author : Alexander Roser; Anton Thunberg; [2023]
    Keywords : sensor fusion; flight mechanics; Kalman filter; extended Kalman filter; unscented Kalman filter; pitot tube; airspeed estimation; simulation;

    Abstract : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. READ MORE
