  1. 16. Deep learning for non-intrusive sensing in turbulence with passive scalars

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Arivazhagan Geetha Balasubramanian; [2021]
    Keywords : Turbulent boundary layer; passive scalar; direct numerical simulation; Prandtl number; Machine learning; convolutional neural network; Turbulent gränsskikt; passiv skalär; direkt numerisk simulering; Prandtl-nummer; maskininlärning; faltningsneurala nätverk;

    Abstract : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. READ MORE

  3. 17. FMCW mmWave Radar for Detection of Pulse, Breathing and Fall within Home Care

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

    Author : Axel Trange; [2021]
    Keywords : ;

    Abstract : Countless of elderly people fall and get hurt within their homes, worldwide, every year, and as they can not always reach out for help themselves, they end up helplessly waiting for someone to notice what has occurred. Throughout this work, it is investigated if remote sensing of the mmWave FMCW radar IWR6843AOPEVM can be adopted to detect the incident of falls, and also detect the vital signs of the human subject.

  4. 18. Fast Parametric Registration and Machine Learning Analysis of Whole-Body MRI Volumes for Age-Related Changes

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Saradh Tiwari; [2021]
    Keywords : ;

    Abstract : Using an extensive dataset provided by the UK Biobank, this project intended to develop methods for registering whole body MRI volumes and analyzing the changes in the body due to ageing. The registration method is developed using the pTV image registration module, which employs a fast registration approach based on parametric total-variation to align volumes to the same local coordinate frames of the reference, for point-wise anatomical region correspondence.

  5. 19. Passive estimation of supply impedances at the meterpoint

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

    Author : Zhanzhan Liu; [2021]
    Keywords : Impedance estimation; Loop theory; System fault detection; Impedansuppskattning; Loopteorin; Systemfelupptäckt;

    Abstract : Modern digital energy meters are installed between the distribution network and customers. Network operators and customers can use those meters to monitor electrical parameters, i.e., voltages and currents and to calculate statistics such as RMS value, fundamental Fourier component, etc. READ MORE

  6. 20. Event-based High Resolution X-ray Imaging using Compton Coincidence Detection

    University essay from KTH/Medicinsk avbildning

    Author : Eva Bergström; [2021]
    Keywords : Photon counting CT; Compton scattering; Compton kinematics; coincidence detection; χ2 test; Fotonräknande CT; Compton-spridning; Compton-kinematik; sammanfallsdetektering; χ2 -test;

    Abstract : Research on photon counting detectors (PCDs) is focused on semiconductor materials, and silicon is a strong candidate to use in PCDs for photon counting computer tomography (CT). In a silicon detector, a significant portion of the counts is due to Compton scattering events. READ MORE
