  1. 1. CFD-simulering av värmeöverföring under upptändningsförlopp av krutraketmotor

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Carl-Otto Olsson Sjögren; [2024]
    Nyckelord :Computational Fluid Dynamics; CFD; Anfyrning; upptändning; CFD; strömningslära; värmeöverföring; termisk strålning; krutraketmotor; konvektion;

    Sammanfattning : SAAB Dynamics producerar och utvecklar flertalet produkter som innehåller krutraketmotorer. Krutraketmotorers prestanda är kraftigt beroende av en effektiv upptändning och det är önskvärt att kunna prediktera detta förlopp numeriskt med god noggrannhet. Ingen etablerad simuleringsmetodik existerar i dagsläget. LÄS MER

  3. 2. Method development of flow cytometry analysis of yeast and lactic acid bacteria viability for alcohol fermentation

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Megha Komahan; [2023]
    Nyckelord :Flow cytometry; yeast; lactic acid bacteria; fermentation; cell viability; applied microbiology; Technology and Engineering;

    Sammanfattning : The usage of yeast in conventional brewing techniques involving alcoholic fermentation is an age-old process. Analyzing the viability and obtaining physiological information regarding the microbial diversity of the fermentation samples plays a pivotal role in obtaining real-time information as well as developing a more efficient process design.

  4. 3. Constraining the Higgs width in Higgs production associated with a top quark pair

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Benjamin Dahlén; [2023]
    Nyckelord :Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Sammanfattning : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

  5. 4. Simulation of p̅p->Λ̄Λ reaction for PANDA.

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Hrbat Arnela; [2023]
    Nyckelord :PandaRoot; ROOT; PANDA; Antiproton-proton collisions; 4-vector kinematics;

    Sammanfattning : The aim of this project was to develop an updated event selection procedure and toevaluate the performance of the procedure for the p̅p->Λ̄Λ reaction using the latestversion of the experiment software, PandaRoot, which is an offline software created forthe needs of the Panda experiment. The written algorithm was checked by comparingthe reconstructed kinematic quantities of the final and composited particles with thekinematic quantities of true particles, and by comparing our results with the resultsobtained using the previous version of PandaRoot.

  7. 5. The Higgs Width in Higgs production in association with a W+ boson

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Wijeratne Mohandiramge Umashi Navisha Fernando; [2023]
    Nyckelord :Higgs boson; Higgs width; off-shell; on-shell; narrow-width approximation; MadGraph5_MC@NLO; W boson; supersymmetry; dark matter; Physics and Astronomy;

    Sammanfattning : The width of the Higgs boson is a quantity that cannot be measured directly from the on-shell Higgs peak; it would have to be measured indirectly. In 2013, Caola and Melnikov developed a method to determine the Higgs width by using off-shell and on-shell cross-sections and applying the narrow-width approximation. LÄS MER
