  1. 1. Flash Pulse Thermography Measurements of Coat Thickness

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Alexander Häggkvist; [2023]
    Nyckelord :Flash Pulse Thermography; Power Function; Dynamical Thermal Tomography;

    Sammanfattning : The application of varnish, metal coats, and paint is a common practice for modifying or enhancing material properties. Metal coats are frequently used as protective layers against corrosion, heat, and wear, while also influencing characteristics like conductivity, weight, and production costs. LÄS MER

  3. 2. Teleoperation of an Autonomous Ground-Penetrating Radar for Non-Destructive Surveying: Design and Implementation

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Rasmus Beyer; [2023]
    Nyckelord :Autonomous; GPR; Robotics;

    Sammanfattning : A lot of features that need to be scanned underground should not be disturbed, from waterlines to unmarked graves. A non-invasive way of probing underground is Ground-Penetrating Radar (GPR). GPR finds differences in materials with radar waves. However, GPR is human-operated and its position is generally determined with a GPS. LÄS MER

    Sammanfattning : In the manufacturing industry, product quality assurance is important to ensure customer safety and product quality. The thesis is based on problems identified with calibration of ultrasonic sensors used in quality assurance of rear shafts for trucks and buses. LÄS MER

  5. 4. Decision framework for maintenance activities in water pipelines: repair or replace? : A literature review and a decision framework proposal

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Letty Fiorella Mora Chirito; [2023]
    Nyckelord :;

    Sammanfattning : The research provides a tool for decision making concerning maintenance activities in water pipelines. The thesis aims to bring attention to the fact that use of modern and faster non-destructive technologies can improve conventional maintenance strategies as long as the results can be interpreted.

  7. 5. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Mathias Billenberg; [2023]
    Nyckelord :TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

    Sammanfattning : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. LÄS MER
