  1. 1. Utvärdering av Centerpoint RTX för GNSS-baserad detaljmätning : En jämförelse med SWEPOS nätverks-RTK

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Henrik Fjellborg; [2022]
    Nyckelord :GNSS; network-RTK; Centerpoint RTX; GNSS; nätverks-RTK; Centerpoint RTX;

    Sammanfattning : SWEPOS nätverks-RTK (Real Time Kinematic) är en nationell korrektionstjänst för GNSS som är flitigt använd i Sverige. En begränsning är dock att den kräver internetuppkoppling och att referensnätet endast täcker Sverige. LÄS MER

  3. 2. Improving the surface finish of the rubber weight plate : Master thesis in mechanical engineering

    Magister-uppsats, Högskolan i Halmstad

    Författare :Joyal Augustine; Steven Simons; [2021]
    Nyckelord :flashing; additive manufacturing; Ullman method; Pugh matrix; rubberweight plates; lever arm; smoothening tool; HGF; lever-spring; Ullman method;

    Sammanfattning : Flash is the unwanted or excessrubber material that presents on the outersurface of themolded rubber product. This will affect the surface finish; it is a cosmetic defect andit can be removed. It forms because of the leak or the excess molded rubber materialbetween the surface of the mold, typically on the parting line, (Jordan Anderson,2014). LÄS MER

  4. 3. Detailed Balance in Quantum Dot Tunneling

    Kandidat-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Plate; [2021]
    Nyckelord :thermodynamics; quantum dot; quantum tunneling; physics; solid state physics; nanoscience; Physics and Astronomy;

    Sammanfattning : Previously recorded data of electron tunneling in and out of a quantum dot (QD) is used to extract knowledge of the state of the system. Using the detailed balance of the system, it is shown that information about the electron temperature in the lead Te, as well as knowledge about the degeneracies of the states in a quantum dot can be obtained from measurements of the tunneling rates in and out of the QD.

  5. 4. Structural design and performance of tube mega frame in arch-shaped high-rise buildings

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Matiss Sakne; [2017]
    Nyckelord :high-rise building; tubed mega frame; arch-shaped structure; finite element method; P-Delta;

    Sammanfattning : A recent development and innovation in elevator technologies have sprawled interest in how these technologies would affect the forms and shapes of future high-rise buildings. The elevator that uses linear motors instead of ropes and can thus travel horizontally and on inclines is of particular interest. LÄS MER

  7. 5. The effect of reinforcement configuration on crack widths in concrete deep beams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Rahimeh Hosseini; Anita Nolsjö; [2017]
    Nyckelord :crack widths; crack development; conventional beams; deep beams; reinforcement stress; tenslie- and crack reinforcement; minimum reinforcement; reinforcement configuration; external loads; non-linear analysis; sprickvidder; ordinära balkar; höga balkar; armeringsspänning; kraft- och sprickarmering; minimiarmering; armeringsutformning; externa laster; icke linär analys;

    Sammanfattning : Reinforced concrete deep beams are known for applications in tall buildings, foundations and offshore structures. Deep beams are structural elements with length and height within the same magnitude and have significantly smaller thickness compared to a conventional concrete beam. LÄS MER
