  1. 11. Method to statistically secure field test results for rock drilling tools

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Frida Olander; [2023]
    Nyckelord :Statistics; Probability; Hypothesis test; Linear regression;

    Sammanfattning : The aim of this project is to find a statistical method that describes survival and outcome of a prototype drilling tool from several references and determine how many references are needed for a statistically secure result. The project also answers which variables that affects the outcome. LÄS MER

  3. 12. Towards Circular Business Models in Swedish Rock and Soil Material Management : An Ecosystem-level Exploration

    Master-uppsats, Linköpings universitet/Projekt, innovationer och entreprenörskap

    Författare :Tova Andreasson; [2023]
    Nyckelord :;

    Sammanfattning : The rapid growth of Swedish metropolitan regions, has led to increased demand for rock and soil materials for building construction and infrastructural work. Sweden's rock and soil material management industry extracts over 100 million tons of aggregate per year, while only succeeding in recycling 1% of it. LÄS MER

  4. 13. A Geophysical Survey of Northern Utö

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Nicole Flanders; [2023]
    Nyckelord :;

    Sammanfattning : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. LÄS MER

  5. 14. Recording Bass-Cabinet: Microphone Choice and Microphone Placement

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Diana Carmona Velazquez; [2023]
    Nyckelord :audio technology; recording bass; recording; bass; microphone choice; bass-cabinet; microphone placement; rock; ljudteknik; mikrofon val; bas; rock;

    Sammanfattning : Research on microphone choice and placement has been previously made for a variety of instruments, such as drums, vocals, and guitar, to name a few. However, in comparison, very little research has been made on the bass-cabinet. LÄS MER

  7. 15. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Chun Hei Ho; [2023]
    Nyckelord :Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Sammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER
