  1. 1. Probability Based Path Planning of Unmanned Ground Vehicles for Autonomous Surveillance : Through World Decomposition and Modelling of Target Distribution

    University essay from Linköpings universitet/Reglerteknik

    Author : Per Liljeström; [2022]
    Keywords : Probability based path planning; Unmanned ground vehicles; UGV; Autonomous surveillance; Cell decomposition; Spatial partitioning; Target distribution modeling; Decay function; Last-seen function; Stochastic processes; Markov chain; Markov process; Markov planner;

    Abstract : The interest in autonomous surveillance has increased due to advances in autonomous systems and sensor theory. This thesis is a preliminary study of the cooperation between UGVs and stationary sensors when monitoring a dedicated area. The primary focus is the path planning of a UGV for different initial intrusion alarms. Cell decomposition, i. READ MORE

  3. 3. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Melina Al Nasser; Linn Gromert; [2022]
    Keywords : Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

    Abstract : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. READ MORE

  4. 4. Design of an Embedded Torque Sensor : Based on Volumetric Strain induced Differential Air Pressure

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Wen Qi; [2022]
    Keywords : Torque; Electronics; Gas sealing; Pressure measurement;

    Abstract : This paper proposes a torque sensor based on the differential air pres- sure measurement method using a new embedded structure. The pro- posed sensor design is an improvement over the previous sensor design. The mechanical sensitivity, resolution, and stress distribution of the new sensor are analyzed by finite element modeling. READ MORE

  5. 5. Smart Scooter : Solving e-scooter safety problems with multi-modal, privacy-preserving sensor technology and machine learning

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

    Author : Beatrice Lovely; [2022]
    Keywords : Smart Devices; Machine Learning; Sensors; Radar; Inertial Measurement Unit; Computer Vision; Smarta Saker; Maskininlärning; Sensorer; Radar; Tröghetsmåttenhet; Dator- seende;

    Abstract : Micromobility ride-share scooters (e-scooters) have become a popular mode of transport in several major cities around the world, yet several safety and accessibility issues stem from how these scooters are operated, including sidewalk riding, unsafe parking and wrong-way riding. This thesis tackles these issues through a novel, privacy-preserving, end-to-end sensor system that employs lightweight machine learning models to provide real-time feedback to users to present unsafe scooter operation.
