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

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Antenna as a sensor for sensing available LTE networks

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

    Författare :Barath Kumar Sathish Kumar; [2022]
    Nyckelord :Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Sammanfattning : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. LÄS MER

  4. 3. Physics-Informed Deep Learning for System Identification of Autonomous Underwater Vehicles : A Lagrangian Neural Network Approach

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

    Författare :Badi Mirzai; [2021]
    Nyckelord :AUV; System Identification; Deep Learning; Physics-Informed Deep Learning; Lagrangian Neural Networks; AUV; System Identifiering; Djupinlärning; Fysik-Informerad Djupinlärning; Lagrangianska Neurala Nätverk;

    Sammanfattning : In this thesis, we explore Lagrangian Neural Networks (LNNs) for system identification of Autonomous Underwater Vehicles (AUVs) with 6 degrees of freedom. One of the main challenges of AUVs is that they have limited wireless communication and navigation under water. LÄS MER

  5. 4. Machine Learning for Water Monitoring Systems

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

    Författare :Robirt Asaad; Carlos Sanchez Ribe; [2021]
    Nyckelord :Federated learning; Internet of Things; Decentralised data; Distributed learning; Long Short-Term Memory;

    Sammanfattning : Water monitoring is an essential process that managesthe well-being of freshwater ecosystems. However, it isgenerally an inefficient process as most data collection is donemanually. By combining wireless sensor technology and machinelearning techniques, projects such as iWater aim to modernizecurrent methods. LÄS MER

  7. 5. Zigbee-uppkopplat vattenlarm

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Malin Malmberg; [2020]
    Nyckelord :zigbee; trådlös kommunikation; elektronik; kretskort;

    Sammanfattning : In this thesis project, a ZigBee-connected water alarm has been constructed. An Xbee 3 ZigBee radio module is programmed to send warnings to an other Xbee 3 ZigBee module if an analogue input falls below the threshold value. An PCB with the Xbee module, resistors, a transistor, LEDs and an battery attachment is manufactured and mounted. LÄS MER
