  1. 1. Implementing Total Electron Content in the Grand Unifed Incoherent Scattering Design and Analysis Program for Investigation of Causes to Scintillations

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Samuel Sonesson; [2023]
    Nyckelord :Total Electron Content; Scintillation; Incoherent Scattering; Ionosphere;

    Sammanfattning : Functionality for calculating and plotting diferent Total Electron Content (TEC) measurements such as Slant Total Electron Content (sTEC), error in sTEC, and VerticalTotal Electron Content (vTEC) was implemented into the data analysis program fromEuropean Incoherent Scattering Scientifc Association (EISCAT), the Grand Unifed Incoherent Scattering Design and Analysis Program (GUISDAP). This utilises a thin-singlelayer model of the ionosphere to convert sTEC into the more analytically useful vTEC. LÄS MER

  3. 2. Mikroplaster i damm från ridunderlag - pilotstudie

    Kandidat-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

    Författare :Niklas Nilsson; [2023]
    Nyckelord :fibersand; underlag; häst; nedbrytning;

    Sammanfattning : Ridsporten är en av de största ungdomsidrotterna inom Sverige. År 2018 beräknades det att cirka 5 miljoner ridtimmar genomförs på landets ridskolor årligen. På grund av Sveriges klimat spenderas mycket av denna tid inom ridhus. LÄS MER

  4. 3. Validating and comparing Total Electron Content estimates from Incoherent Scatter Radar and Global Positioning System

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Sven Molenkamp; [2023]
    Nyckelord :;

    Sammanfattning : This thesis aims to analyze the possibilities to use Incoherent Scatter Radar to measure Total Electron Content in the ionosphere. By comparing the results from EISCATselectron density data over altitude and time to Total Electron Content estimates from GPS satellites and their receivers through a climatology as well as qualitative analysis for separate EISCAT experiments a comparison between the two is conducted.

  5. 4. Recovery of Cobalt and Copper from Zambia Slag via Sulphidisation with Gypsum

    Master-uppsats, KTH/Materialvetenskap

    Författare :Lloyd Masuzyo Mseteka; [2021]
    Nyckelord :;

    Sammanfattning : The main objective of this research was to recover copper and cobalt from slags coming from copper processing on the Copperbelt province of Zambia. Pyrometallurgical processing of copper sulphide concentrate generates huge tonnes of slag wastes. LÄS MER

  7. 5. Method to assess machinability of engineering steels using coated carbide tools

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Petra Hedberg; [2021]
    Nyckelord :Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

    Sammanfattning : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested. LÄS MER
