  1. 21. Contrast improvement of few-cycle pulses

    Magister-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Xiaoying Zhang; [2019]
    Nyckelord :;

    Sammanfattning : The intense few-cycle laser pulses play an important role in the investigations of laser-plasma interaction. However, one of the biggest challenges in their generation is the reduction of temporal intensity contrast by introducing undesired pre-pulses and a long pedestal. Two techniques were investigated in this work to improve the contrast. LÄS MER

  2. 22. Investigation of magnetic order in nickel-5d transition metal systems

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Konstantinos Papadopoulos; [2019]
    Nyckelord :muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Sammanfattning : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. LÄS MER

  3. 23. Economic and production consequences of current forest management in mature Scots pine (Pinus sylvestris) forests in Lithuania

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Rokas Šatinskas; [2019]
    Nyckelord :National Forest Inventory; Pinus sylvestris; thinning; rotation lenght; alternatives; economic consequences;

    Sammanfattning : Forestry takes up a major part in the economy of Northern Europe countries. The aim of this work is to evaluate the economic and production consequences in Scots pine (Pinus sylvestris) stands in Lithuania based on the data of the National Forest Inventory (NFI). Scots pine stands cover the biggest area of Lithuanian forests. LÄS MER

  4. 24. FinTech: The role of Perceived cybersecurity and Organizational trust

    Master-uppsats, Umeå universitet/Företagsekonomi; Umeå universitet/Företagsekonomi

    Författare :David Laurent; Robin Sinz; [2019]
    Nyckelord :FinTech; Cybersecurity; TAM; Trust;

    Sammanfattning : Context: The advent of the Information and Communication Technologies mostly referred to “digitalization”; offers a new paradigm. Information technology is now perceived as a disruptive innovation capable of shaking up the traditional financial industry. LÄS MER

  5. 25. Development of a new rotational angle selector attachment for tightening tools

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Författare :Moinak Banerjee; Sanket Kulkarni; [2019]
    Nyckelord :Product development; angle selector; torque; nut-runner; optimisation; Produktutveckling; vinkelväljare; vridmoment; mutterdragare; optimering;

    Sammanfattning : The design solution for angle selector attachment is developed and carry forward based on initial case study done by KTH Södertäjle students. This project is carried out to find the answers for few questions viz. potential concept design solution, considering the requirements given by Scania that needs to be fulfilled. LÄS MER
