  1. 1. Cavity Beam Position Monitors State of the Art and Design Studies in the Context of the ILC Project

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Författare :Laura Karina Pedraza Motavita; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The aim of this master thesis project is the study and evaluation of the design of cavity beam position monitors (BPM) for the International Linear Collider (ILC) project. The state-of-the-art of BPMs is investigated to determine the most appropriate existing BPM design for the requirements of the ILC. LÄS MER

  3. 2. Educational superintendents' perspectives of a national networking project on school segregation in Sweden : Lessons to be learned?

    Master-uppsats, Stockholms universitet/Institutionen för pedagogik och didaktik

    Författare :Daniel Nilsson Brodén; [2023]
    Nyckelord :Superintendent; school superintendent; school segregation; educational leadership; educational equity; professional development; governance; networks;

    Sammanfattning : World-wide, countries struggle with providing equitable education to all children, where the socioeconomic (SES) background of the students does not affect their educational attainment and achievement. School segregation has been shown in previous research to exacerbate the influence of family background on educational achievement and attainment. LÄS MER

  4. 3. Faster than Nyquist Signaling with Spatial Coupling

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Haoran Liu; Lingwei Zhang; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).

  5. 4. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling

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

    Författare :Calle Stenberg; [2021]
    Nyckelord :double quantum dots quantum rings tight-binding aharonov-bohm g-factor enhancement InAs; Physics and Astronomy;

    Sammanfattning : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.

  7. 5. Exploring Spin-Transport in Graphene

    L3-uppsats, Uppsala universitet/Energimaterialens fysik

    Författare :Giacomo Luani; [2021]
    Nyckelord :;

    Sammanfattning : Graphene is one of the most popular new materials both in the academic and private sectors. Its striking properties allow for radical redesigns of many electronic or storage devices. In this report, first, a brief theoretical description of graphene’s band structure is given using the tight/binding method, along with its unique properties. LÄS MER
