  1. 26. 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

  3. 27. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Mizgin Coskun; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. READ MORE

  4. 28. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jules Reniaud; [2022]
    Keywords : Technology and Engineering;

    Abstract : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. READ MORE

  5. 29. Object classification in the simulation environment using ultrasonic sensor arrays

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Haoyun Ou; [2022]
    Keywords : Master Thesis; Object Classification; Machine Learning; Ultrasonic; Sensor; Simulation;

    Abstract : With the wide application of machine learning technologies in advanced driver assistance systems of vehicles, object classification on obstacles has attracted much attention. Ultrasonic sensors are mainly used to measure the distance to obstacles under the condition of low-speed movement. READ MORE

  6. 30. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Lassi Linnala; [2022]
    Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.
