  1. 16. 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

    Sammanfattning : Purpose: This study aims to identify the operational and financial outcomes of companies implementing the no-code manufacturing execution system (MES). Methods: This study has been conducted using inductive reasoning to develop new theories in this unexplored subject. LÄS MER

  4. 18. Reactor Chemistry in LWR SMRs : Determination of the rate constant for the reaction between boric acid and hydroxyl radicals

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Fredrik Petersson; [2023]
    Nyckelord :LWR; SMR; Water chemistry; Radiolysis; Boric acid; LWR; SMR; vattenkemi; Radiolys; Borsyra; Hydroxylradikal;

    Sammanfattning : Ett problem vid byggandet av nya kärnkraftverk för elproduktion är de stora investeringskostnaderna samt den långa tiden det att få tillstånd för en reaktor och bygga den. Nyligen färdigställdes den tredje reaktorn vid Olkiluoto I Finland, den tog 18 år att färdigställa exklusive tiden att få tillstånd för reaktorn. LÄS MER

  5. 19. ISAR Imaging Enhancement Without High-Resolution Ground Truth

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Moltas Enåkander; [2023]
    Nyckelord :SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

    Sammanfattning : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. LÄS MER

  7. 20. Combustibility study of resin for warm magnet coils used at CERN

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Juan Carlos Lopez Santiago; [2023]
    Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER
