  1. 1. AC Gate Bias Stress of 4H-SiC MOSFETs : An investigation into threshold voltage instability of SiC Power MOSFETs under the influence of bipolar gate stress

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

    Author : Agnimitra Saha; [2023]
    Keywords : Silicon Carbide; Gate Bias Stress; Threshold Voltage; On-state Resistance; Temperature; kiselkarbid; gate spännings-stress; tröskelspänning; on-resistansen; temperatur;

    Abstract : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. READ MORE

  3. 2. Procedural generation and weathering of building facades : Replicating shape and distribution of wear-and-tear on real-world building facades

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

    Author : Love Wessman; [2023]
    Keywords : procedural modeling; building facades; wear and tear; procedurell modellering; byggnadsfasader; slitage;

    Abstract : Manual modeling of building facades can be a cumbersome process. Instead, procedurally modeling building facades is a practical and quick way to achieve impressive visual results. This paper presents a method for prototyping 2D facades existing in a 3d environment, with the inclusion of shading-based procedural wear-and-tear. READ MORE

  4. 3. Drones for Sea Rescue: Lab and Field Experiments on Camera Gimbal Control

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Alexander Sandström; [2023]
    Keywords : Drones; Search and Rescue; Unmanned Aerial Vehicle; UAV; gimbal; camera control; ArduPilot; Quality of Experience; QoE; Technology and Engineering;

    Abstract : The objective of this thesis has been to improve the camera controls of a fixed-wing drone to be used in maritime search-and-rescue operations by the Swedish Sea Rescue Society (SSRS). A gimbal control interface (GCI) has been implemented that displays the video feed of the drone camera while taking control inputs from a joystick that moves its view in real-time. READ MORE

    University essay from KTH/Teknisk akustik

    Author : Silvia Milani; [2023]
    Keywords : Ride comfort; Steering wheel vibrations; Resonance excitations; Åkkomfort; Rattvibrationer; Resonansexcitationer;

    Abstract : The vehicle manufacturing sector is constantly evolving, and corporations are fully aware of increased consumer expectations for both driver and passenger´s comfort. SCANIA CV AB, as one of the largest Swedish manufacturers of commercial vehicles, has put an emphasis on this area. READ MORE

  6. 5. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gusten Zandler Andersson; [2023]
    Keywords : Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Abstract : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. READ MORE
