  1. 1. Misalignment effects on the physics performance of the inner tracker upgrade at the ALICE experiment

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

    Författare :Jesper Karlsson Gumprecht; [2024]
    Nyckelord :ALICE; ITS; ITS2; ITS3; O2; O2Physics; Distortion; Misalignment; Alignment; Realignment; Physics and Astronomy;

    Sammanfattning : This thesis deals with the physics performance of an approved inner tracker upgrade of the ALICE experiment involving a novel and ultra-thin silicon detector with a cylindrical geometry. During the thesis work, a method was developed in simulations to induce distortions to the detector’s geometry, and the resulting loss in physics performance was evaluated. LÄS MER

  3. 2. Computational Fluid Dynamics and Modeling of a Free Surface Flow

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Mathieu Marmier; [2023]
    Nyckelord :CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Sammanfattning : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. LÄS MER

  4. 3. Loading tests on composite concrete columns : A comparison between composite columns made of permanent 3DPC formwork filled with SCC and columns made of homogenous SCC

    Master-uppsats, KTH/Betongbyggnad

    Författare :Abdulla Al-Bazarkan; Hussain Alahmad; [2023]
    Nyckelord :;

    Sammanfattning : In order to achieve increased sustainability when casting concrete structures this thesis investigates the possibility of utilizing 3D-printing to construct formwork and digitalize construction. By digitizing construction less workers are needed and therefore less capital. LÄS MER

  5. 4. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Calum Kvernes Macpherson; [2023]
    Nyckelord :Bulge; Milky Way; Kinematics; Galpy; Dwarf Stars; Physics and Astronomy;

    Sammanfattning : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

  7. 5. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Bill Claesson; [2023]
    Nyckelord :;

    Sammanfattning : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. LÄS MER
