  1. 1. Velocity Control of a Mobile Charger in a Wireless Rechargeable Sensor Network

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Emilia Haltorp; [2023]
    Keywords : Wireless Sensor Networks; Mobile Charger; Wireless Energy Transfer; Traveling Salesman Problem; Trådlösa Sensornätverk; Mobil laddare; Trådlös strömöverföring; Handelsresandeprobleme;

    Abstract : Wireless sensor networks (WSN) are one of the most rapidly evolving technical areas right now. They can be used in a lot of different applications, environmental monitoring and health applications being two examples. The sensors can be placed in hazardous and remote environments since there is no need for cabling or manual maintenance. READ MORE

  3. 2. Designing a communication controller for a wireless sensor network : Practical considerations and comparisons

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

    Author : Frej Larssen; Axel Karlsson; [2023]
    Keywords : Wireless sensor networks; IoT; LTE-M; Comparison; Trådlösa sensornätverk; IoT; LTE-M; Jämförelse;

    Abstract : As the use of Internet of Things (IoT) devices increases, so does the number of available hardware platforms. Today there exists a broad range of hardware components that could be used to develop an IoT product and selecting the right ones is a difficult task. READ MORE

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

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

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

    Abstract : 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. READ MORE

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

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

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

    Abstract : 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. READ MORE

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

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

    Author : Theodor Olsson; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE
