1. 1. Case Study: Assessing the Security of a ZigBee Smart HomeNetwork

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Författare :Robal Saker; Obaida Abu Issa; [2024]
   Nyckelord :ZigBee; vulnerabilities; smart home; technical user; non-technical user;

   Sammanfattning : Utilizing the ZigBee protocol is pervasive in the context of smart homes, offering substantial convenience to individuals. However, smart home devices commonly handle significant quantities of real-world information, potentially giving rise to concerns related to information leakage. LÄS MER

3. 2. Heart rate estimation from wrist-PPG signals in activity by deep learning methods

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

   Författare :Marie-Ange Stefanos; [2023]
   Nyckelord :Deep Learning; Medical Data; Signal Processing; Heart Rate Estimation; Wrist Photoplethysmography; Djup lärning; Medicinska Data; Signalbehandling; Pulsuppskattning; Handledsfotopletysmograf;

   Sammanfattning : In the context of health improving, the measurement of vital parameters such as heart rate (HR) can provide solutions for health monitoring, prevention and screening for certain chronic diseases. Among the different technologies for HR measuring, photoplethysmography (PPG) technique embedded in smart watches is the most commonly used in the field of consumer electronics since it is comfortable and does not require any user intervention.

4. 3. A small step for a sensor : Detecting limited spatial movement with mobile AR

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Johan Fallström; [2023]
   Nyckelord :computer-science; software; development; software development; ar; augmented reality; unity; ar foundation; arkit; arcore; exergame; heart failure; rehabilitation; world tracking; mobile ar; mobile augmented reality; movement tracking; p-iii; heart-exg; exergaming; step counter; spatial movement; slam;

   Sammanfattning : In this paper, a technical overview will be provided for a developed mobile exergame, with a particular focus on its movement tracking. By utilizing spatial movement readout from the AR algorithm, we've managed to create an easy to use exergame that allows the user to track their horizontal movement. LÄS MER

5. 4. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

   Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Sara Lenman; Sofia Blaad; [2023]
   Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

   Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

7. 5. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

   Master-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Arvin Razavi; [2023]
   Nyckelord :IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

   Sammanfattning : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. LÄS MER
