  1. 1. Utvärdering av larmgränser för extensometermätningar vid bergbyggande : En fallstudie vid Henriksdals reningsverk

    Master-uppsats, KTH/Byggvetenskap

    Författare :Jesper Spång; [2022]
    Nyckelord :Rock engineering; Alarm limits; Extensometers; Failure probability; Rock mass deformation; Bergbyggande; Larmgränser; Extensometrar; Brottsannolikhet; Deformation av berg;

    Sammanfattning : Vid en ombyggnation av Henriksdals reningsverk har ett vertikalschakt utformats och anlagts. Under berguttaget tillämpades extensometermätningar för att följa upp deformationer i en bergpelare mot en befintlig tunnel. Mätningar utfördes automatiserat och regelbundet. LÄS MER

  3. 2. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device

    Master-uppsats, KTH/Geoinformatik

    Författare :Kepan Gao; [2022]
    Nyckelord :U-Net; deep learning; tunnel monitoring; structural health monitoring; crack detection; mobile mapping system;

    Sammanfattning : Infrastructures like bridges and tunnels are significant for the economy and growth of countries, however, the risk of failure increases as they getting aged. Therefore, a systematic monitoring scheme is necessary to check the integrity regularly. LÄS MER

  4. 3. New Concept Development of a Blood Glucose-Balancing Functional Beverage

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Fiona Ernesta; [2021]
    Nyckelord :nordic berries; blood-glucose; functional beverage; food engineering; Technology and Engineering;

    Sammanfattning : Type 2 Diabetes Mellitus (T2DM) have known to be one of the most common degenerative diseases which highly correlate with lifestyle, including consumption habits. It cannot be denied that the availability and accessibility to high processed food, high in carbohydrates play an important role on increasing the risk of T2DM. LÄS MER

  5. 4. Comparison of Tunnel Convergence Measurement Methods

    Master-uppsats, KTH/Fastigheter och byggande

    Författare :Olof Erlandsson; [2020]
    Nyckelord :tunnel; convergence; displacement; tilt; sensor; tunnel; konvergens; förskjutning; tilt; sensor;

    Sammanfattning : When creating cavities below ground, movements occur in the surrounding soil due to disrupted equilibrium. In tunnel constructions these displacements are referred to as tunnel convergence. This report compares four dierent methods for monitoring tunnel convergence with regards to both measurement precision and method cost. LÄS MER

  7. 5. The Impact of Fracture Orientation on the Choice of Grout Fan Geometry - a Statistical Analysis

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Fredrik Osterman; [2019]
    Nyckelord :Rock Fissure Grouting; Grout Fan Geometry; Geology; Discrete Fracture Network; Sprickinjektering i berg; skärmgeometri; geologi; diskreta spricknätverk;

    Sammanfattning : Water ingress into rock tunnels is a problematic phenomenon – especially in urban areas – as a lowered groundwater table may cause harmful settlements. Furthermore, too much ingress can be an incentive for the environmental court to halt the tunnel process, in order to protect the nature as part of a national interest. LÄS MER
