  1. 1. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesper Jansson; Wilhelm Nordgren; [2023]
    Nyckelord :Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Sammanfattning : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  3. 2. Non-linear effects in the ATLAS track-counting luminosity measurement

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Daniel Gautam; [2023]
    Nyckelord :Particle physics; CERN; ATLAS; Track counting; Luminosity; Monte Carlo; Track Selection;

    Sammanfattning : In this thesis the linearity of the ATLAS track-counting luminosity measurement is studied using two different sets Monte Carlo simulated crossings of proton-proton bunches. A primary high-momentum, or hard, interaction must be chosen for the Monte Carlo simulation. LÄS MER

  4. 3. Determining backgrounds with misidentified leptons in the ATLAS Higgs boson analysis

    Master-uppsats, KTH/Fysik

    Författare :Leo Qiyuan Hu; [2023]
    Nyckelord :Particle Physics; ATLAS detector; Fake Factor method; Higgs boson; lepton misreconstruction; misidentified events; Partikelfysik; ATLAS detektorn; Fake Factor-metoden; Higgs boson; lepton felrekonstruktion; felidentifierade händelser;

    Sammanfattning : This thesis presents an analysis of misidentified leptons in the Higgs boson decaychannel H → W W ∗ → lνlν. Misidentified leptons, resulting from jets misidentifiedas leptons, mimic the signal of a Higgs boson decay, resulting in a backgroundcontribution to the signal. LÄS MER

  5. 4. Simulation and optimisation of a manufacturing process : A case study of a high mix and low volume manufacturing process at Atlas Copco

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Axel Lund Borg; [2023]
    Nyckelord :Bottleneck analysis; simulation; value stream map; production management;

    Sammanfattning : Companies are constantly seeking new ways to increase their efficiency and flexibility to be able to meet the market demand, industry 4.0 has provided companies with new tools that enables them to better track the performance of a process and more easily optimise it. LÄS MER

  7. 5. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment

    Kandidat-uppsats, KTH/Fysik

    Författare :Simon Thor; [2022]
    Nyckelord :ATLAS; CERN; particle physics; simulation; Python; C ; standard model; emerging jets; long-lived particles;

    Sammanfattning : Dark matter, the unknown matter that constitutes 85% of all matter in the universe, is one of the greatest mysteries in fundamental physics. One theory that might explain dark matter predicts that there are long-lived particles known as dark pions. LÄS MER
