  1. 1. Radio Environment Compensation in a Narrowband IoT Positioning System : Using Radio Signal Metrics Between Stationary Devices

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

    Author : Elin Berglund; [2023]
    Keywords : Positioning; IoT; machine learning; range estimation; Positionering; IoT; maskininlärning; avståndsuppskattning;

    Abstract : The Internet of Things (IoT) has emerged as a powerful tool for meeting our need to collect information about and interact with our environments. One important aspect of this technology is positioning which imposes requirements on both the energy consumption and the arrangement of the systems. READ MORE

  3. 2. Modelling and Optimisation of Relativistic Magnetron with Transparent Cathode : Applications for High-Power Microwaves

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : David Sawert; [2023]
    Keywords : Relativistic Magnetron; RM; High-Power Microwaves; HPM; Particle-in-Cell; PIC; MAGIC3D; TE11;

    Abstract : This thesis aimed to investigate the relativistic magnetron (RM), which is a high-power microwave (HPM) source. Since the RM can generate high-intensity microwave radiation, it can be used as a pulsed electromagnetic weapon to target electronic systems in different objects, such as drones, missiles, or vehicles.

  4. 3. Dataset based on volunteer campaign to optimize novel sensor for muscle quality

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Sophia Holmqvist; [2022]
    Keywords : sarcopenia; microwaves; medical imaging;

    Abstract : This project had its primary focus on running a campaign to recruit healthy volunteers for a test study involving the utilization of a microwave sensor and ultrasound measurements. The key system used was the Muscle Analyzer System (MAS), which consisted of the Bandstop Filter Sensor (BFS), a microwave sensor transmitting microwaves into the selected medium through transmission and a FieldFox Vector Network Analyzer which was used to transmit these microwaves.

  5. 4. Control of 3D-printed Hand Prosthetic via Intra-body Fat Channel Communication

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Eric Trollsås; [2022]
    Keywords : Fat-IBC; IBAN; Prosthetics; ATE Phantom; Phantom Tissue; 3D-printing; ZigBee;

    Abstract : Intra-Body Communication (IBC) is a prospective technology where human tissue may be used as a signal medium in order to transmit useful data within the human body. Proposed applica- tions of this technology are prosthetics control or implanted device communication, potentially by establishing an Intra-Body Area Network (IBAN), which could further be enhanced by other IoT applications and 5G radio systems.
