  1. 1. Flow of charged particles in Pb-Pb and pp collisions at the LHC

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

    Author : Mohamed Berkat; [2024]
    Keywords : Quark Gluon Plasma; QGP; Quantum Chromodynamic; QCD; flow coefficients; Event Plane; Cumulants; ALICE; Physics and Astronomy;

    Abstract : This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. READ MORE

  3. 2. Don't Fall! A Case Study on Market-scoping For Early-stage Technologies and the Role of Sensemaking

    University essay from Handelshögskolan i Stockholm/Institutionen för företagande och ledning

    Author : Julia Klingestam Lundqvist; [2023]
    Keywords : Market-scoping; early-stage technologies; dynamic capabilities; sensemaking; high tech;

    Abstract : Effectively managing uncertainty requires flexibility and strategic trade-offs, even so for firms basing their product-offer on early-stage technologies. Managers' role in strategic decisions have previously been overlooked, focusing more on predetermined market spaces based on technology, firm, and industry characteristics. READ MORE

  4. 3. Named Entity Recognition for Case Narratives of Adverse Event Reports

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Jayant Yadav; [2023]
    Keywords : ;

    Abstract : In the field of pharmacovigilance (PV), signal detection and assessment activities play a crucial role. They require a PV assessor to read through countless adverse event reports which is manual labor-intensive work. To ease the reading process, visual highlighters can be provided by leveraging natural language processing techniques. READ MORE

  5. 4. Navigating narratives: A framing analysis of AUKUS in Chinese state media

    University essay from Lunds universitet/Centrum för öst- och sydöstasienstudier

    Author : Alison Clark; [2023]
    Keywords : AUKUS; Trilateral security collaboration; Chinese state media; Media framing; Social Sciences;

    Abstract : This thesis investigates how the framing of AUKUS, a trilateral security and defense collaboration consisting of Australia, United Kingdom, and the United States, is portrayed by Chinese state media. AUKUS, established on September 15, 2021, is mainly focusing on providing Australia with nuclear-powered submarine technology. READ MORE

  6. 5. Event categorisation and Machine-learning Techniques in Searches for Higgs Boson Pairs in the ATLAS Experiment at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Milads Emadi; [2023]
    Keywords : Particle Physics; ATLAS; BDT; Boosted Decision Tree; Decision Tree; Optimization; Machine Learning; Analysis;

    Abstract : This thesis investigates the pair production of Higgs bosons (di-Higgs events) at the ATLAS experiment in the Large Hadron Collider (LHC), focusing on the channel where one Higgs boson decays into two bottom quarks and the other decays into two tau leptons. The main objective was to determine whether introducing a split in the invariant mass of the decay products from the two Higgs bosons (the di-Higgs mass) and using this as an analysis variable improves the sensitivity of the Boosted Decision Tree (BDT) machine learning algorithm to the di-Higgs signal.
