  1. 1. 3D Facial Modelling for Valence Estimation

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

    Författare :Ioannis Athanasiadis; [2022]
    Nyckelord :Computer Graphics; Machine Learning; Representation Disentanglement; Valence Estimation;

    Sammanfattning : We, as humans, purposely alter our facial expression to convey information during our daily interactions. However, our facial expressions can also unconsciously change based on external stimuli. LÄS MER

  3. 2. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sergi Tarroc Gil; [2021]
    Nyckelord :Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

    Sammanfattning : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. LÄS MER

  4. 3. Shape optimization of axial cooling fan via 3D CFD simulation and surrogate modeling

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Martin Granlöf; [2021]
    Nyckelord :Fan noise; shape optimization; mesh morphing; computational fluid dynamics; computational aeroacoustics; Efficient Global Optimization; Reynolds-averaged Navier-Stokes;

    Sammanfattning : Due to legislative reasons and environmental concerns the automotive and transport sector are shifting their focus from traditional internal combustion engine (ICE) vehicles to development of battery electric vehicles (BEVs). This brings new challanges to design of cooling systems where axial fans are one of the key components. LÄS MER

  5. 4. Finite Element Head ModelPersonalization by Mesh Morphing

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Yann Levin; [2021]
    Nyckelord :Biomechanics; Finite element; Head models; Image Registration; Mesh morphing; Personalization.;

    Sammanfattning : Finite Element (FE) head models are very convenient tools forthe study of Traumatic Brain Injuries (TBIs) but lack significantanatomical details for the investigation of morphology or age-dependantinjury mechanisms. In this context, the use of deformable registrationalgorithms for the generation of personalized head models is veryconsistent for the development of improved protection systems likehelmets. LÄS MER

  7. 5. Mesh Morphing Technique used with Open-Source CFD Toolbox in Multidisciplinary Design Optimisation

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Rok Lapuh; [2018]
    Nyckelord :;

    Sammanfattning : Nowadays, the product design process relies on computer simulations more than ever. Compared to the experimental tests, they allow substantially more designs to be evaluated. Moreover, computer simulations allow a search for the optimum. That is why a fast and efficient transition from one design iteration to the next is necessary. LÄS MER
