   Sammanfattning : Over the last decade, machine learning has gained a lot of traction in many areas, and with the advent of new GPU models that include acceleration hardware for neural network inference, real-time applications have also started to take advantage of these algorithms. In general, machine learning and neural network methods are not designed to run at the speeds that are required for rendering in high-performance real-time environments, except for very specific and typically limited uses.

3. 2. Towards Fully Dynamic Surface Illumination in Real-Time Rendering using Acceleration Data Structures

   Författare :Pierre Moreau; Parallella System; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer graphics; Real-time; Ray tracing; Caustics; Global illumination;

   Sammanfattning : The improvements in GPU hardware, including hardware-accelerated ray tracing, and the push for fully dynamic realistic-looking video games, has been driving more research in the use of ray tracing in real-time applications. The work described in this thesis covers multiple aspects such as optimisations, adapting existing offline methods to real-time constraints, and adding effects which were hard to simulate without the new hardware, all working towards a fully dynamic surface illumination rendering in real-time.

4. 3. Efficient Methods for Volumetric Illumination

   Författare :Frida Gyllensvärd; Anders Ynnerman; Anders Persson; Markus Hadwiger; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Modern imaging modalities can generate three-dimensional datasets with a very high detail level. To transfer all the information to the user in an efficient way there is a need for three-dimensional visualization. LÄS MER

5. 4. Development of optical diagnostics of plasma-related phenomena and applications

   Författare :Yupan Bao; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-thermal plasma; plasma-assisted combustion; laser diagnostics; spectroscopy; coded imaging; Fysicumarkivet A:2022:Bao;

   Sammanfattning : Optical diagnostics techniques based on coded imaging were developed and applied for plasma-related phenomena and applications. The signal of interest is first encoded with a sinusoid pattern either by structured laser illumination or implement of a diffractive optical element, such as a grating, along the optical path of the signal.

7. 5. Modelling and Retrieval of Forest Parameters from Synthetic Aperture Radar Data

   Författare :Maciej Soja; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic Aperture Radar; biomass estimation; modelling; forest;

   Sammanfattning : Currently, one of the most uncertain factors in the global carbon cycle models lies in the terrestrialcarbon stock, mainly forests. The available methods for global forest resource mapping provide onlyrough estimates of biomass, the most relevant practical quantity related to carbon stock. LÄS MER
