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

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

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

    Sammanfattning : 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. LÄS MER

  3. 2. Pursuits of the body: Sensory realities in Clive Barker’s The Hellbound Heart

    Kandidat-uppsats, Göteborgs universitet/Institutionen för språk och litteraturer

    Författare :Rebecca Sonesson; [2023-07-07]
    Nyckelord :Horror; Clive Barker; gothic literature; The Hellbound Heart; literary studies; body horror; new materialism; splatterpunk; the weird;

    Sammanfattning : This thesis explores how corporeality is represented within horror literature, and if the depicted corporeality can be read in a more material way rather than in a metaphorical way. By using the character of Frank from Clive Barker’s novel The Hellbound Heart, the relation between representations of corporeality and physical materiality is examined. LÄS MER

  4. 3. A C++ Matrix library for computing the Gateaux derivative of the Fermi-Dirac operator

    Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :William Samuelsson; [2023]
    Nyckelord :C ; Quantum Chemistry; Matrix functions;

    Sammanfattning : Computing the Fermi-Dirac operator is done through recursive polynomial expansions, using the SP2 and SP2 Acc algorithms. The Gateaux derivative is computed for both schemes by mapping the zeroth and first order matrices onto a block upper triangular matrix, which is implemented in Python using Numpy arrays to store full matrices and in C++ by first constructing a basic matrix library to use as blocks in a later created block upper triangular matrix library which only directly references two blocks in a 2 x 2 block matrix.

  5. 4. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Cyrus Ourak Pour; [2023]
    Nyckelord :COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

    Sammanfattning : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

  7. 5. The Collapse of Decoherence : Can Decoherence Theory Solve The Problems of Measurement?

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Karl Herlin; [2023]
    Nyckelord :quantum mechanics; quantum physics; philosophy of physics; interpretation of quantum mechanics; measurement problem; problem of preferred basis; problem of non-observability of interference; problem of definite outcomes; environment induced superselection rules; copenhagen interpretation; decoherence; irreducibility of classical concepts;

    Sammanfattning : In this review study, we ask ourselves if decoherence theory can solve the problems of measurement in quantum mechanics. After an introduction to decoherence theory, we present the problem of preferred basis, the problem of non-observability of interference and the problem of definite outcomes. LÄS MER
