  1. 1. Sandvärmesystemet : Det första uppvärmningssystemet i personvagnar

    Kandidat-uppsats, Uppsala universitet/Kulturvård

    Författare :Fredrik Åkerblom; [2024]
    Nyckelord :Sandvärme;

    Sammanfattning : 1856 började Statens Järnvägar med gods- och persontrafik och någon gång under början av 1860-talet så uppstod önskemålet att ha uppvärmning i förstaklasskupéer under de kalla vintermånaderna. Därmed så infördes den första uppvärmningen i personvagnar. LÄS MER

  3. 2. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Simon Garpenquist; [2023]
    Nyckelord :Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

    Sammanfattning : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. LÄS MER

  4. 3. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Jonathan Envall; [2023]
    Nyckelord :PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Sammanfattning : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

  5. 4. Design of an Industrial Bin Picking Station

    Master-uppsats, Lunds universitet/Innovation

    Författare :Jonathan Ramb; [2023]
    Nyckelord :bin picking; computer vision; automation; robotics; 3D Scanning; Technology and Engineering;

    Sammanfattning : With the ever-increasing demand for automation, new ways to optimize production lines are needed. The aim of this thesis is to complete an industrial automation task by employing a concept in robotics known as bin picking. The concept involves organizing objects by picking them out of a cluttered bin using an industrial robot. LÄS MER

  7. 5. Misfire Detection in Heavy Duty Diesel Engines Using Knock Sensors

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Carl Sjöstedt; [2023]
    Nyckelord :ICE; combustion engine; combustion engines; Scania; diesel; knock; knock sensor; knock sensors; misfire; misfire detection;

    Sammanfattning : In this thesis the possibility of using knock sensors for misfire detection in heavy duty diesel engines is investigated. This is of great interest due to many emission legislations getting stricter, especially in the US where robust misfire detection is mandatory for these types of engines. LÄS MER
