1. 1. 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.

3. 2. Approximating material area, volume,and velocity for belt conveyor systemapplications using 3D depth sensor technology

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Viktor Centing; [2023]
   Nyckelord :ToF depth sensor; LiDAR sensor; LMS4000; Visionary T mini; BCS; ToF applications; velocity approximation;

   Sammanfattning : Time of Flight (ToF) technology describes products or systems which measure distance by calculating the distance emitted light travels before bouncing off its surroundings and ending back up at the system. Since the early 2000s, many advancements in the area of ToF systems have been made leading to much use for the ToF variant LiDAR. LÄS MER
