  1. 1. Exact Solutions of Soliton Equations and Dynamical Systems

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Fredrik Jonsson; [2023]
    Keywords : ;

    Abstract : This report investigates how one can construct soliton solutions to the following solitonequations: the Korteweg-de Vries equation, the Benjamin-Ono equation, and the spinBenjamin-Ono equation by making rational pole ansätze, which are ansätze that dependon eponymous pole parameters moving in the complex plane. In doing so we demonstratea connection between these soliton solutions and the class of integrable dynamical systemsknown as Calogero-Moser systems. READ MORE

  3. 2. Atomic Structure Calculations Using Configuration-Interaction And Many-Body Perturbation Theory For Spectral Modelling Of Neutron Star Mergers : Example Of Ce I - Iv

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Fredrik Plane; [2023]
    Keywords : Computational atomic physics; Atomic physics; Physics; Astronomy; Astrophysics; Neutron stars; Stars; Relativisitc atomic physics; Configuration-interaction; Perturbation theory; Many-body perturbation theory;

    Abstract : The binary neutron star merger of 2017 and its corresponding electromagnetic signature resembling that of a kilonova has been one of the most groundbreaking astrophysical occurrences in the last decade. Indications of r-process nucleosynthesis in this event presents new opportunities for learning about the astrophysical origin of heavy elements. READ MORE

  4. 3. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Fredrik Plane; [2022]
    Keywords : Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

    Abstract : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. READ MORE

  5. 4. K-POP: Predicting Distance to Focal Plane for Kato-Katz Prepared Microscopy Slides Using  Deep Learning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Hannes Fredrik Kuchelmeister; [2022]
    Keywords : ;

    Abstract : Neglected tropical diseases affect approximately one-sixth of the global population. Most are treatable with widely available medicine, however, diagnosis is expensive and slow. An automated solution using low-cost microscopes and machine learning could alleviate this by scanning for parasite eggs in smear samples. READ MORE

  6. 5. Analysing the quality of PlaneRCNN plane parameters using a structure from motion system

    University essay from Lunds universitet/Matematik LTH

    Author : Fredrik Österberg; [2021]
    Keywords : structure from motion; PlaneRCNN; neural network; sfm; computer vision; RANSAC; planes; room reconstruction; Mathematics and Statistics; Technology and Engineering;

    Abstract : This report aims to compare the plane parameters given by the PlaneRCNN network with those created by using a Structure from Motion (SfM) solution on the same data. Several datasets are used, and the results from PlaneRCNN are evaluated by using the camera matrices from the SfM solution and applying these along with scaling and coordinate transformations.
