  1. 1. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Alfred Norberg; [2023]
    Nyckelord :Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

    Sammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER

  3. 2. 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

  4. 3. The Effect of Whole-Body Vibration Preconditioning on High-Altitude-Induced Venous Gas Emboli

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Tommaso Tuci; [2020]
    Nyckelord :Whole-Body Vibration; Vibration; High-Altitude Aviation; Venous Gas Emboli; VGE; Decompression sickness; DCS;

    Sammanfattning : Decompression sickness (DCS) is a risk associated with high-altitude aviation and diving. During these activities, decompression may lead to supersaturation of inert gas dissolved in bodily tissues and subsequently activate bubble formation in various bodily tissues, including in venous blood, known as venous gas emboli (VGE).

  5. 4. LPS, Local Positioning System : Småskaligt positioneringssystem baserat på avståndsmätning med ultraljud

    Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Pontus Myhrberg; Emil Åberg; David Nyman; [2018]
    Nyckelord :ultraljud; positionering; avståndsmätning;

    Sammanfattning : Målet med projektet var att med ultraljudsteknik tillverka en produktsom kan bestämma positionen i ett område på 10x10 m. För att uppnådetta tillverkades tre enheter kapabla att sända och mottagaultraljudssignaler. LÄS MER

  7. 5. Measurement System to Monitor Interface Level Between Oil and Water in a Rapidly Rotating System

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)
