  1. 1. 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

  3. 2. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Jonathan Karlsson; [2023]
    Nyckelord :Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

    Sammanfattning : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.

  4. 3. Acoustic Focusing of Lysozyme Crystals

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Måns Junestrand; [2023]
    Nyckelord :Protein Crystals; Lysozyme Crystals; Ultrasound; Acoustic Focusing; SFX; Biomedical Physics; Proteinkristaller; Ultraljud; Lysozymkristaller; Akustisk fokusering; SFX; Biomedicinsk fysik;

    Sammanfattning : Acoustic focusing of microscale protein crystals with acoustophoresis technology could reduce clogs during experiments with the scientific technique serial femtosecond x-ray crystallography (SFX). SFX determines molecular structures of proteins, these structures are valuable in drug discovery and fundamental biomedical research. LÄS MER

  5. 4. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

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

    Författare :Diogo Antunes; [2023]
    Nyckelord :Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Sammanfattning : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.
