  1. 11. An Open-Source Autoencoder Compression Tool for High Energy Physics

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Gallén; [2023]
    Keywords : Physics; Particle Physics; Analysis; Machine Learning; Neural Networks; Autoencoders; Data Compression; Lossy Compression; Baler; Physics and Astronomy;

    Abstract : A common problem across scientific fields and industries is data storage. This thesis presents an open-source lossy data compression tool with its foundation in Machine Learning - Baler. Baler has been used to compress High Energy Physics (HEP) data, and initial compression tests on Computational Fluid Dynamics (CFD) toy data have been performed. READ MORE

  3. 12. Application of Physics-Informed Neural Networks for Galaxy Dynamics

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Lucas Barbier; [2023]
    Keywords : ;

    Abstract : Developing efficient and accurate numerical methods to simulate dynamics of physical systems has been an everlasting challenge in computational physics. Physics-Informed Neural Networks (PINNs) are neural networks that encode laws of physics into their structure. READ MORE

  4. 13. Chemoreception of a Two-Dimensional Cell with Multilayer Diffusion

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Steffi Schijf; [2023]
    Keywords : biophysics; chemoreception; receptors; multilayer diffusion; diffusion; Physics and Astronomy;

    Abstract : Previously, Berg and Purcell found an expression for the diffusion current of particles into a set of receptors in their paper Physics of Chemoreception. These receptors were assumed to be uniformly distributed on a spherical cell's surface and the receptors where idealized as circular patches. READ MORE

  5. 14. Error propagation in nuclear models

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

    Author : Artis Mucenieks; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

  6. 15. Enhancing HiDAC Model Performance : Evaluating Unity Physics against Original approach in regards to diverse environments

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Karlo Stjepan Angelic; Tilda Jansson; [2023]
    Keywords : ;

    Abstract : The High-Density Autonomous Crowds (HiDAC) model is an interesting crowd simulation model due to its unique ability to parameterize human characteristics. It is used in various applications such as urban planning, emergency management, and entertainment applications. READ MORE
