  1. 1. Event-Based Visual SLAM : An Explorative Approach

    University essay from Uppsala universitet/Signaler och system

    Author : Johan Rideg; [2023]
    Keywords : event camera; neuromorphic; SLAM; visual odometry;

    Abstract : Simultaneous Localization And Mapping (SLAM) is an important topic within the field of roboticsaiming to localize an agent in a unknown or partially known environment while simultaneouslymapping the environment. The ability to perform robust SLAM is especially important inhazardous environments such as natural disasters, firefighting and space exploration wherehuman exploration may be too dangerous or impractical.

  3. 2. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors

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

    Author : Xingyu Zhao; [2023]
    Keywords : keywords here: Deadbeat Predictive Current Control; Permanent Magnet Synchronous Motor; Flux Linkage Nonlinearity; Parameter Inaccuracies; Nonlinear Feedforward Compensation; Delayed Integral Action.; Deadbeat-prediktiv strömreglerin; Permanenta magnet-synkronmotorn; Ickelinjäriteter i flödeslänkningen; Felaktigheter i parametrar; Icke-linjär framåtmatningskompensation; Fördröjd integralåtgärd.;

    Abstract : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. READ MORE

  4. 3. Respiratory Motion Correction in PET Imaging: Comparative Analysis of External Device and Data-driven Gating Approaches

    University essay from KTH/Fysik

    Author : Nina Lindström Söraas; [2023]
    Keywords : PET CT; Tomographic reconstruction; Respiratory gating techniques; Image registration; Motion correction; PET CT; Tomografisk rekonstruktion; Gating tekniker; Bildregistrering; Rörelsekorrigering;

    Abstract : Positron Emission Tomography (PET) is pivotal in medical imaging but is prone to artifactsfrom physiological movements, notably respiration. These motion artifacts both degradeimage quality and compromise precise attenuation correction. READ MORE

  5. 4. Real-Time Video Super-Resolution : A Comparative Study of Interpolation and Deep Learning Approaches to Upsampling Real-Time Video

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

    Author : Erik Båvenstrand; [2021]
    Keywords : Super-Resolution; Real-Time; Deep Learning; Upsampling; Computer Vision; Machine Learning; Motion Compensation; Temporal Coherence; Superupplösning; Realtid; Djupinlärning; Uppsampling; Datorseende; Maskininlärning; Rörelsekompensation; Temporalt Sammanhängande;

    Abstract : Super-resolution is a subfield of computer vision centered around upsampling low-resolution images to a corresponding high-resolution counterpart. This degree project investigates the suitability of a deep learning method for real-time video super-resolution. READ MORE

  6. 5. Self-levelling Platform Concept for a Winch-based, Single Point Absorbing, Wave Energy Converter

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Anton Bergman; Robin Eriksson; Lars-Fredrik Grahn; [2020]
    Keywords : Point absorbing; Self-levelling; Wave power; Winch-based; Nivellerande; Punktabsorberande; Vågkraft; Vinschbaserat;

    Abstract : This report covers a bachelor thesis project to design a concept for a levelling system to a point absorbing wave energy converter that uses a winch with a chain, which has restricted capabilities to bending and thus requires a system which compensates for this. First of all, a literature study was made to see if there were any technologies that could be used, and also a wide search for information about the wave conditions in the Baltic sea were performed to find what requirements would be necessary for the concept to be able to withstand the conditions faced there.
