  1. 1. Modeling wave behavior with linear wave theory

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Elsa Renström; [2024]
    Nyckelord :;

    Sammanfattning : This thesis aimed to look at the behaviours of the water beneath waves from a modeling and simulations point of view. We have investigated how to use Linear wave theory (LWT) to model the kinematic movements in water governed by free ocean waves. The model assumes the surface to consist of a superposition of sinusoidal waves. LÄS MER

  3. 2. A New Approach for Positioning Human Body Models Utilising the 3D-Graphics Program Blender

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Jesper Eiderbäck; Felix Jahnke; [2023]
    Nyckelord :Human Body Model; HBM; positioning; THUMS; Blender; Radial basis function.; Mänsklig kroppsmodel; HBM; positionering; THUMS; Blender; Radiell Basfunktion;

    Sammanfattning : A finite element human body model (FE HBM) is a detailed virtual model of the human body that, for example, is used for simulating traffic accidents. A problem with HBMs is that there is no simple way to position the HBMs in non-standard positions. LÄS MER

  4. 3. Manipulering av bildhastighet och dess känslomässiga påverkan på tittarupplevelse vid olika format

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

    Författare :William O'Grady; Emil Währme; [2023]
    Nyckelord :motion pictures; film; tv; video; viewer perception; HFR; frame rate; frame interpolation; motion smoothing;

    Sammanfattning : Frame rate is a fundamental element of creating the illusion of movement in video based media. For almost a century film has been produced in agreement with a standard frame rate of 24 frames per second, originally established due to technical limitations. LÄS MER

  5. 4. Effects of visualization using different convolution kernels in Julia

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Nils Forsberg; Axel Nilsson; [2023]
    Nyckelord :Convolution; Julia; visualization; streamlines; vorticity; interpolation; filter;

    Sammanfattning : Many real-world engineering problems require large amounts of data in order to accurately model and predict outcomes. However, this data is often noisy, sampled and discontinuous, making the data difficult to process and giving rise to incorrect models. LÄS MER

  7. 5. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Författare :Frida Hermansson; [2023]
    Nyckelord :Pulmonary Hypertension; pulmonary hypertension; improving; physiological-guided; machine learning; neural networks; NN; artificial neural networks; non-invasive; PH; tricuspid regurgitation; peak tricuspid regurgitation velocity; tricuspid regurgitation velocity; right ventricular systolic pressure; VGG16; Unet; TR-CNN; CNN; pulmonell hypertension; förbättra; fysiologisk-guidning; neurala nätverk; trikuspidal regurgitation; maximal trikuspidal regurgitation; icke-invasivt;

    Sammanfattning : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).
