  1. 1. Superconducting gates for InP HEMTs

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Sebastian Alveteg; [2023]
    Nyckelord :Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

    Sammanfattning : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. LÄS MER

  3. 2. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Aayush Desai; [2023]
    Nyckelord :Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

    Sammanfattning : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. LÄS MER

  4. 3. Measuring possible indicators of successful academic writing among EFL teaching undergraduate students

    Uppsats för yrkesexamina på avancerad nivå, Malmö universitet/Institutionen för kultur, språk och medier (KSM)

    Författare :Gustav Wibell-Kähr; Filip Nilsson Ek; [2022]
    Nyckelord :academic writing; information literacy; source criticism; reporting verbs; academic vocabulary; EFL;

    Sammanfattning : The purpose of this paper is to investigate several potential indicators of successful academic writing and their connection to assignment grades as a possible path toward better teaching of academic writing at the upper secondary level in Sweden. These indicators are referencing (REF), academic vocabulary (AV), and reporting verbs (RV). LÄS MER

  5. 4. SJÄLVSKATTAD TILLFREDSSTÄLLELSE MED AKTIVITET OCH UPPLEVD AKTIVITETSBALANS En kvantitativ studie om unga vuxna med psykisk ohälsa

    Kandidat-uppsats, Göteborgs universitet/Institutionen för neurovetenskap och fysiologi

    Författare :Hanad Yusuf; Yonas Rosengren; [2020-04-22]
    Nyckelord :Occupational therapy; Mental health; Young adult; Explorative analysis;

    Sammanfattning : Bakgrund Psykisk ohälsa ökar bland unga vuxna i dagens samhälle och kan leda till negativa konsekvenser. Utifrån ett arbetsterapeutiskt perspektiv är aktivitet ett centralt begrepp som är viktigt för personens hälsa och välbefinnande. LÄS MER

  7. 5. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

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

    Författare :Hamidreza Rastan; [2019]
    Nyckelord :Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Sammanfattning : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.
