  1. 1. LiDAR-Equipped Wireless Sensor Network for Speed Detection on Classification Yards

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

    Författare :Isak Olsson; André Lindgren; [2021]
    Nyckelord :LiDAR; Internet of Things IoT ; Wireless Sensor Networks WSN ; Classification yards; 6LoWPAN; RANSAC; LiDAR; Sakernas internet; Trådlösa sensornätverk; Rangerbangårdar; 6LoWPAN; RANSAC;

    Sammanfattning : Varje dag kopplas tusentals godsvagnar om på de olika rangerbangårdarna i Sverige. För att kunna automatiskt bromsa vagnarna tillräckligt mycket är det nödvändigt att veta deras hastigheter. En teknik som har blivit populär på sistone är Light Detection and Ranging (LiDAR) som använder ljus för att mäta avstånd till objekt. LÄS MER

  2. 2. Estimating energy consumption of Wifi transceiver circuits on a single board computer

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

    Författare :Frida Mattsson; [2021]
    Nyckelord :Transceiver circuit; 802.11; energy consumption; software profiling; single-board computer; Raspberry Pi; Transceiver; 802.11; energikonsumtion; mjukvaruprofilering; enkortsdator; Raspberry Pi;

    Sammanfattning : This work comprises an approximation of the energy consumption of the transceiver circuit in a single board computer. Single board computers, such as the Raspberry Pi 4 Model B that is used here, are usually cheap and therefore more accessible. LÄS MER

  3. 3. Real-time Classification of Multi-sensor Signals with Subtle Disturbances Using Machine Learning : A threaded fastening assembly case study

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

    Författare :Theodor Olsson; [2021]
    Nyckelord :Multivariate time series classification; Residual-based fault detection; Low-pass filter; Support vector machine; Threaded fastening assembly; Multivariat tidserieklassificering; Residual-baserad feldetektering; Lågpass-filter; Stödvektormaskin; Åtdragningsmontering;

    Sammanfattning : Sensor fault detection is an actively researched area and there are a plethora of studies on sensor fault detection in various applications such as nuclear power plants, wireless sensor networks, weather stations and nuclear fusion. However, there does not seem to be any study focusing on detecting sensor faults in the threaded fastening assembly application. LÄS MER

  4. 4. Topology optimization for distributed consensus in multi-agent networks

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

    Författare :Johan Niklasson; Oskar Hahr; [2019]
