  1. 1. Proximity to Dissimilar Firms and Universities: Investigating the Impact on Start-up Survival Rates in Sweden and the United States

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Johan Birgersson; [2023-07-19]
    Nyckelord :;

    Sammanfattning : This study explores the impact of proximity to dissimilar firms and universities on start-up survival rates in Sweden and the United States. By investigating the relationship between firm density and start-up survival in two countries with distinct institutional contexts, this research aims to contribute to the existing literature.

  3. 2. Error propagation in nuclear models

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Artis Mucenieks; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

  4. 3. Assessing the Impacts of Future Climate Change on Tree Cover Densities in Nigeria with a Proposal of States Suitable for Climate Mitigation

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Paula von Tschischwitz; [2023]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : With an increase in temperature (T) and a change in precipitation (P) patterns due to climate change, global conditions for tree growth are changing and shifting. While some areas experience an increase in P, favoring tree growth, many regions are also predicted to show a decrease in P, leading to trends of desertification. LÄS MER

  5. 4. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

    Författare :Axel Gudmundsson; [2023]
    Nyckelord :Photoluminescence; Upconversion; Plasmons; ZnO;

    Sammanfattning : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

  7. 5. Flashlamp Annealing for Improved Ferroelectric Junctions

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

    Författare :Theodor Blom; [2023]
    Nyckelord :Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

    Sammanfattning : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. LÄS MER
