  1. 1. Development of a guide system for free neutron oscillation searches at the European Spallation Source

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

    Author : Linnéa Björk; [2023]
    Keywords : ESS; neutrons; dark matter; antimatter; neutron guides; Physics and Astronomy;

    Abstract : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.

  2. 2. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    University essay from Uppsala universitet/Tillämpad beräkningsvetenskap

    Author : Khalil Daloul; [2023]
    Keywords : Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Abstract : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. READ MORE

  3. 3. Event Geometry and Anisotropic Flow in Proton-Proton Collisions

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Johannes Holst; [2021]
    Keywords : high energy physics; particle physics; proton; collision; quark-gluon plasma; flow; anisotropy; anisotropic flow; elliptic flow; initial state; geometry; eccentricity; gaussian; cms; alice; lhc; Physics and Astronomy;

    Abstract : We seek to better understand the relationship between an anisotropic distribution of partons in the initial state of pp-collisions and the amount of elliptic flow. We do this through the implementation of a new model that is based in generating positions for multiparton interactions from the uneven volume created by the overlap of two Gaussians. READ MORE

  4. 4. On Pollard's rho method for solving the elliptic curve discrete logarithm problem

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Jenny Falk; [2019]
    Keywords : elliptic curves; Pollard s rho method; elliptic curve discrete logarithm problem; cryptography; adding walk; mixed walk; cycle-detecting algorithm; iterating function; random walk;

    Abstract :     Cryptosystems based on elliptic curves are in wide-spread use, they are considered secure because of the difficulty to solve the elliptic curve discrete logarithm problem. Pollard's rho method is regarded as the best method for attacking the logarithm problem to date, yet it is still not efficient enough to break an elliptic curve cryptosystem. READ MORE

  5. 5. Solving an inverse problem for an elliptic equation using a Fourier-sine series.

    University essay from Linköpings universitet/Matematiska institutionen

    Author : Olivia Linder; [2019]
    Keywords : Regularization; ill-posed problem; Fourier-sine series; Regularisering; illaställt problem; Fouriersinusserie;

    Abstract : This work is about solving an inverse problem for an elliptic equation. An inverse problem is often ill-posed, which means that a small measurement error in data can yield a vigorously perturbed solution. Regularization is a way to make an ill-posed problem well-posed and thus solvable. READ MORE
