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

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

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

   Abstract : 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. READ MORE

3. 2. Improving the Accuracy of FFT-based GPGPU Ocean Surface Simulations

   University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

   Author : Jacob Eriksson; Joakim Wingård; [2022-12-01]
   Keywords : computer graphics; 3D graphics; real-time rendering; Fourier transform; FFT; simulation; GPGPU; interactive; ocean wave spectrum; oceanography;

   Abstract : In this paper, we explore how the current state of the art in real-time ocean simulations can be improved in terms of simulation accuracy, while preserving performance. Current methods, both in academia and in the industry, simulate an ocean model in frequency space on the GPU, convert said model on an approximately frame-byframe basis to the spatial domain using the Fourier transform, and then read back the resulting heightfield to the CPU as input to the application’s physics engine.

4. 3. Application of a flight chip in an underwater quadcopter

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Oscar Onn; [2021]
   Keywords : ;

   Abstract : This paper aims to describe the entire processof developing and testing an underwater quadcopter using aflight chip (FC) as the steering computer. The problem withthe FC is that the physics differs between using an air droneand an underwater drone. Most importantly, buoyancy is notnegligible underwater, while it is negligible in the air.

5. 4. Reaching for the limit of stability

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Weiyi Cui; [2020]
   Keywords : nuclear physics; HFBTHO; DFT; machine learning; artificial neural network; Physics and Astronomy;

   Abstract : In this project, calculations for the total binding energy of all even-even nuclei available from experimental data are performed using the HFBTHO program. An artificial neural network is applied to train the information obtained from the HFBTHO calculations and predict the binding energy for the nuclei. READ MORE

6. 5. HfO2 and ITO Resistive Random-Access Memory

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Mattias Åstrand; [2020]
   Keywords : RRAM; Resistive switching; HfO2; ITO; Physics and Astronomy;

   Abstract : The purpose of this work is of evaluating the choice of HfO2 and ITO as the dielectric and the top electrode in high performance resistive random-access memory (RRAM), respectively. The study is twofold, as it quantifies performance according to standard figures of merit for this technology, as well as provides insight into the physics of current conduction for this material choice.
