    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Freddie Manheij; [2022]
    Nyckelord :Light control system; Open loop system; Closed loop system; Home automation; Illumination sensor; Microcontroller; Arduino; Performance; Usability; End user; Development; Pulse width modulation; LED lamps; Dimmer; Ljusstyrningssystem; Öppen slinga; Sluten slinga; Hemautomation; Belysningssensor; Mikrokontroller; Arduino; Prestanda; Användbarhet; Slutanvändare; Utveckling; Pulsbreddsmodulering; LED-lampor; Dimmer;

    Sammanfattning : Decreasing energy consumption has become increasingly important in recent times due to climate change. The average temperature is increasing across the planet, and with it, an increase in droughts and other climate disasters can be seen. There are multiple ways to decrease energy consummation, and one of them is to regulate the light in a building. LÄS MER

    Sammanfattning : This Master’s thesis work is about the conditions that can affect the identification of defects in lithium-ion batteries. In lithium batteries, there are cathode and anode, which are separated with electrically insulative but ionically conductive electrolytes and separators. LÄS MER

  5. 4. Towards Robust Localization : Deep Feature Extraction with Convolutional Neural Networks

    Kandidat-uppsats, Luleå tekniska universitet/Signaler och system

    Författare :Erik Carlbaum Ekholm; [2020]
    Nyckelord :Autonomous Vehicles; MAVs; Visual Odometry; Localization; Convolutional Neural Networks; Optical Flow;

    Sammanfattning : The ability for autonomous robotics to localize themselves in the environment is crucial and tracking the change of features in the environment is key for visual based odometry and localization. When shifting into rough environments of dust, smoke and poor illumination as well as erratic movements common in MAVs however, that task becomes substantially more difficult. LÄS MER

  7. 5. SORTED : Serial manipulator with Object Recognition Trough Edge Detection

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rikard Bodén; Jonathan Pernow; [2019]
