  1. 16. Dynamic Covariance Modelling Using Generalised Wishart Processes

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Fredrik Nilsson; [2023]
    Nyckelord :Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

    Sammanfattning : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. LÄS MER

  3. 17. Piecing Together the Past : A study about the significance of digitally accessing family records between Australia and England, and the key players responsible

    Master-uppsats, Uppsala universitet/Institutionen för ABM

    Författare :Natanya Berggren Newton; [2023]
    Nyckelord :Genealogy; digital archives; archival unity; Australia; England; information gap;

    Sammanfattning : With the rise in popularity of ancestral research many people have had to search for some records abroad and are therefore reliant on access to archives in more than one country. One of the countries heavily reliant on archives abroad is Australia, a multicultural country that received many British settlers from 1788. LÄS MER

  4. 18. Geometric Phases In Weak Measurements

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Isabela Dias; [2023]
    Nyckelord :Geometric phase; Weak measurements; Weak values;

    Sammanfattning : We explore a natural extension of the Abelian geometric phase factor in sequences of incomplete measurements to include high dimensional quantum states in the weak measurement scenario. To achieve the goal, we focus on sequential weak measurements of non-commuting projectors and combine the idea of weak measurements and the notion of a non-Abelian geometric phase. LÄS MER

  5. 19. Naturmiljöer och Vandringsleder för Alla - Framtagandet av en universellt utformad vandringsapplikation

    Master-uppsats, Lunds universitet/Certec - Rehabiliteringsteknik och Design

    Författare :Hjalmar Tingberg; [2023]
    Nyckelord :universell utformning; tillgänglig naturturism; användarcentreraddesign; vandringsapplikation; Technology and Engineering;

    Sammanfattning : Ungefär en tredjedel av Sveriges befolkning är friluftsaktiva i skog- och mark minst en gång i veckan. Detta intresse ökar för varje år, och under Covid-19-pandemin nådde andelen friluftsintresserade nya höjder där femtio procent av Sveriges totala befolkning aktivt deltog i utomhusaktiviteter.

  7. 20. Hållbarhetsredovisning i gruvbranschen : En kvalitativ studie om gruvbolags hållbarhetsredovisning i samband med en skandal

    Kandidat-uppsats, Södertörns högskola/Företagsekonomi

    Författare :Betsabe Perez Cancino; Iman Hussein; [2022]
    Nyckelord :Sustainability report; sustainability reporting; strategies; GRI; mining industry; scandals; corporate crisis; Hållbarhetsrapport; hållbarhetsredovisning; strategier; GRI; gruvbranschen; skandaler; företagskriser;

    Sammanfattning : Background  Previous studies show a high level of uncertainty in the mining industry. Stakeholders require transparent sustainability reports from mining companies due to the high risk of accidents. In recent years, several failures causing disastrous consequences have occured in the industry. LÄS MER
