  1. 1. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

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

    Författare :Simon Wozny; [2020]
    Nyckelord :topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

    Sammanfattning : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. LÄS MER

  2. 2. Additive manufacturing and radio frequency filters : A case study on 3D-printing processes, postprocessing and silver coating methods

    Master-uppsats, KTH/Industriell produktion

    Sammanfattning : Additive manufacturing (AM) is an attractive way to shorten development time, reduce product weight and allow the manufacturing of more complex products than by conventional manufacturing processes. The problem arises when the previous traditional manufacturing requirements need to be fulfilled by AM as well as the volume production capability. LÄS MER

  3. 3. Processtyrningens påverkan på medarbetares resultat i ett tjänsteföretag

    Kandidat-uppsats, Uppsala universitet/Företagsekonomiska institutionen; Uppsala universitet/Företagsekonomiska institutionen

    Författare :Johan Björck; Carl Ericson; [2020]

    Sammanfattning : Processorientering är en organisationsform som fokuserar på processer istället för hierarkier. Inom organisationsformen processorientering styrs organisationen med processtyrning som innefattar ett antal komponenter som ska ge styreffekter och driva företagets resultat. LÄS MER

  4. 4. Micromachining of microfluidicsystems using a nanosecond laser : Process optimization and application

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Per Söderbäck; [2019]
    Nyckelord :Acoustophoresis; Acoustofluidics; Laser micromachining; Microfabrication; Particle manipulation; Ultrasound;

    Sammanfattning : Microfluidics is a field of research that enables the manipulation of fluids in the submillimetre length scale. The technology allows the development of lab-on-a-chip devices, which are miniaturized systems for chemical and biological analysis. LÄS MER

  5. 5. English spelling errors in Swedish high school : An investigation of English spelling errors among Swedish high school students and their possible causes

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för humaniora

    Författare :Gule Akman; [2019]
    Nyckelord :Spelling error; Swedish English learners; Second Language Acquisition SLA ; Transfer; Language Gender; Gender spelling mistakes; Program orientation; Uppsala Learner English Corpus ULEC ;

    Sammanfattning : This study investigates spelling errors among Swedish students of English. The purpose of this research is to develop a better understanding of the causes of spelling errors and to investigate whether there are any differences between program orientation and gender. The participants are English A students from Swedish high schools in year 1. LÄS MER
