    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Nsioh Elvis Nkioh; [2022]
    Nyckelord :geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Sammanfattning :      One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

  2. 2. Flexible Solution for an Automatic Assembly Cell

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Majed Wakim; [2022]
    Nyckelord :Flexible Manufactring System; Automatic Feeder System; Robotic Simulation; Automated assembly;

    Sammanfattning : This project is being carried out in collaboration with Parker Hannifin. The main objective of this project is to achieve a simulation of an automatic assembly cell for the assembly of the CRVs in the P70 hydraulic valve assembly line. The robotic cell uses the line layout to perform the assembly. LÄS MER

  3. 3. Modeling of a Hydraulic Rock Drill for Condition Monitoring

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Adam Kagebeck; Mahdi Najafi; [2022]
    Nyckelord :Condition Monitoring System; Hydraulic Rock Drill; Diagnostic; Modeling; State Space Model;

    Sammanfattning : This thesis aims to investigate the possibility of using a mathematical model to detect several common faults in a hydraulic rock drill. To this end, a parameterized state space model of the hydraulic drill, which simulate its behavior, is created. LÄS MER

  4. 4. Jämförelse mellan olika jordbearbetningsmetoder vid etablering av vårkorn

    M1-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Henrik Frisk; [2022]
    Nyckelord :plog; kultivator; tallrikskultivator Carrier; ultragrund; vårkorn; etablering; skotträkning; axräkning; tilling; spring barley; reduced tilling;

    Sammanfattning : I dagens jordbruk effektiviseras allt för att spara tid, pengar och miljö, men samtidigt bedriva en effektiv odling som ger hög avkastning. Det är därför intressant att studera vilken jordbearbetningsmetod som är effektivast för att få en bra etablering samt en bra axbildning, som bygger hög skörd. LÄS MER

  5. 5. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Wanyi Li; [2022]
    Nyckelord :Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

    Sammanfattning : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. LÄS MER
