  1. 6. A Performance Comparison of Java Streams and Imperative Loops

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

    Author : Magnus Åkerfeldt; [2023]
    Keywords : Java streams; performance; benchmarking; loops; functional programming; Java streams; prestanda; loopar; funktionell programmering;

    Abstract : The Stream API was added in Java 8. With the help of lambda expressions (anonymous functions), streams enable functional-style operations on sequences of elements. READ MORE

  3. 7. Three-body decay as a baryon polarizer

    University essay from Uppsala universitet/Kärnfysik

    Author : Carl Johan Königsson; [2023]
    Keywords : Three-body decay; polarization; CP violation; hyperon; resonance; Trekroppssönderfall; polarisation; CP-brytning; hyperon; resonans;

    Abstract : According to the standard model, the size of CP violation in the weak decay Λ → pπ- is predicted to be ∼ 10-5. This means that a very high precision is needed if we want to be able to measure it. READ MORE

  4. 8. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

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

    Author : Þóra Karlsdóttir; [2023]
    Keywords : Dwarf Galaxy; Milky Way; Physics and Astronomy;

    Abstract : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations.

  5. 9. An Investigation and Comparison of Machine Learning Methods for Selecting Stressed Value-at-Risk Scenarios

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Moa Tennberg; [2023]
    Keywords : Value-at-Risk; Total margin; Procyclicality; Machine learning; Binary classification; Supervised learning; Unsupervised learning; Random forest; Multilayer perceptron;

    Abstract : Stressed Value-at-Risk (VaR) is a statistic used to measure an entity's exposure to market risk by evaluating possible extreme portfolio losses. Stressed VaR scenarios can be used as a metric to describe the state of the financial market and can be used to detect and counter procyclicality by allowing central clearing counterparities (CCP) to increase margin requirements.

  6. 10. Development of an event generator for antihyperon-hyperon pair production in antiproton-proton collisions

    University essay from Uppsala universitet/Kärnfysik

    Author : Vitor Jose Shen; [2022]
    Keywords : MC event generator; Antihyperon-hyperon pair; Antiproton-proton collisions; PANDA; ROOT; 4-vector kinematics; Angular distribution;

    Abstract : The goal of this project was to develop a lightweight Monte-Carlo (MC) event generator for hyperon pair production in antiproton-proton collisions, and demonstrate it in one of the hyperon decay reaction channels, which is collisions of proton and antiproton to lambda hyperon and anti-lambda hyperon, and they decay to antiproton-positive pion pair, and proton-negative pion pair. The prototype of this external MC event generator we presented here is based on the software framework of ROOT. READ MORE
