  1. 21. Vibration-Based Terrain Classification for an Autonomous Truck

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

    Author : Lucas Lovén; [2022]
    Keywords : Autonomous vehicles; machine learning; surface identification; obstacle identification; signal processing; time series classification; Autonoma fordon; maskininlärning; detektering av underlag; detektering av hinder; signalhantering; tidsserie klassifiering;

    Abstract : This thesis is focused on developing vibration based terrain classification for an autonomous mining truck. The goal is to classify between good and bad gravel roads as well as good and bad asphalt roads. Current literature within vibration based terrain classification has been focused to a great extent on smaller research vehicles. READ MORE

  2. 22. Investigation of Vibration in Electrical Circuit used in Maritime Applications

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Keywords : Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

    Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

  5. 25. Study of luminescent and energy properties of CsPbBr3 and CsPbI3 nanoplatelets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Taddeo Salique; [2022]
    Keywords : quantum confinement; nanoplatelets; CsPbBr3; CsPbI3; semiconductor; exciton; perovskite nanocrystals;

    Abstract : Halide perovskite semiconductor nanocrystals have been studied a lot recently because they allow a precise control over the entire visible emission spectrum and as a result, the possibility of a variety of light-emitting applications. In this study, cesium lead bromide CsPbBr3 and cesium lead iodide CsPbI3 nanoplatelets of 3, 4 and 5 monolayers (ML) have been synthesized. READ MORE
