1. 1. Real-time Soft Body Simulation using Extended Position-Based Dynamics and Tetrahedral Deformation

   Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :William Kamnert; [2023]
   Nyckelord :Physically based animation; Soft body deformation; Volumetric models; GPU parallel computing;

   Sammanfattning : Background. Several methods have been used to simulate soft body deformation, such as mass-spring systems and position-based dynamics. This has been done using tetrahedral mesh models for preservation of shape and volume. LÄS MER

3. 2. Anticipating Glacier Lake Outburst Floods (GLOFs): an impact-based forecasting framework for managing GLOF risks in Nepal.

   Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Grace Muir; [2023]
   Nyckelord :Anticipatory Action; Impact-based Forecasting; Glacier Lake Outburst Flood; Nepal; Risk-informed Early Action; Prediction; Disaster Risk Management; Science General;

   Sammanfattning : Glacier lake outburst floods (GLOFs) are an increasingly documented threat across the Himalayan region, wherein Nepal is situated. GLOFs involve a rapid discharge of water from a lake situated at the side, front, within, beneath, or on the surface of a glacier. LÄS MER

4. 3. Applying spatially and temporally adaptive techniques for faster DEM-based snow simulation

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Simon Andreasson; Linus Östergaard; [2023]
   Nyckelord :Real-time simulation; DEM; GPU; Games; Computer graphics; Realtidssimulering; DEM; GPU; Spel; Datorgrafik;

   Sammanfattning : Background. Physically-based snow simulation is computationally expensive and not yet applicable to real-time applications. Some of the prime factors for this cost are the complex physics, the large number of particles, and the small time step required for a high-quality and stable simulation. LÄS MER

5. 4. Evaluation of Performance and Image Quality for Voxel Cone Tracing

   Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Johannes Finn; [2022]
   Nyckelord :computer graphics; voxel cone tracing; voxel-based rendering;

   Sammanfattning : Voxel cone tracing (VCT) is a rendering method designed to approximate global illumination in a fast and efficient way. Global illumination means to render not only the direct lighting of a scene but also light from indirect sources, simulating how light in the real-world tend to bounce around and illuminate even the areas that are occluded from a direct light source.

7. 5. An evaluation of deep learning models for urban floods forecasting

   Master-uppsats, KTH/Geoinformatik

   Författare :Yang Mu; [2022]
   Nyckelord :Urban flooding forecasting; Convolutional neural networks; Deep learning; Physically-based simulation; Recurrent neural network; Stadsöversvämningsprognoser; konvolutionella neurala nätverk; djupinlärning; fysiskt baserad simulering; återkommande neurala nätverk;

   Sammanfattning : Flood forecasting maps are essential for rapid disaster response and risk management, yet the computational complexity of physically-based simulations hinders their application for efficient high-resolution spatial flood forecasting. To address the problems of high computational cost and long prediction time, this thesis proposes to develop deep learning neural networks based on a flood simulation dataset, and explore their potential use for flood prediction without learning hydrological modelling knowledge from scratch.
