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

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Towards a feedback system for upper body bodyweight exercises using multiple inertial measurement units : A user-centred approach

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Panagiota Papadopoulou; [2023]
    Nyckelord :IMU sensors; bodyweight training; machine learning; real-time feedback; push-ups; tricep dips; plank;

    Sammanfattning : This thesis explores the feasibility of developing an affordable and easy-to-use feed- back system that leverages information from multiple inertial measurement units (IMUs) to identify mistakes during upper body bodyweight training and provide real-time feedback to the user. To develop the system, a human-centered approach was used, which involved conducting semi-structured interviews with movement ex- perts and a workshop with targeted end-users to understand their needs.

  4. 3. Assisted GNSS Positioning using State Space Corrections

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Oskar Philipsson; [2023]
    Nyckelord :positioning; GNSS; SSR; EKF; sensor fusion;

    Sammanfattning : Classical GNSS based positioning has accuracy limitations due to many sources oferror. The error sources range from clock errors and orbit errors toerrors due to variations in atmospheric propagation delays. One way to improve GNSSpositioning is to generate real time corrections using a GNSS reference network. LÄS MER

  5. 4. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels

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

    Författare :Jennifer Ly; [2023]
    Nyckelord :Correlational method; gas analysis; real time measurements; speed of sound; thermal conductivity; methane pyrolysis; rocket nozzle cooling; Korrelationsmetod; gasanalys; mätningar i real tid; ljudhastighet; värmeledningsförmåga; metanpyrolys; kylning av raketmunstycken iv;

    Sammanfattning : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.
