  1. 21. A Rank Score Model of Variants Prioritization for Rare Disease

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Nanxing Liu; [2023]
    Nyckelord :machine learning; variants; rare disease;

    Sammanfattning : The diagnosis of genetic illnesses has undergone a revolution with advancements in sequencing technology. Next-generation sequencing (NGS) has become a standard practice in genetic diagnostics, enabling the identification of various genetic variations. LÄS MER

  3. 22. A Multi-Level Extension of the Hierarchical PCA Framework with Applications to Portfolio Construction with Futures Contracts

    Master-uppsats, KTH/Matematisk statistik

    Författare :Kajsa Bjelle; [2023]
    Nyckelord :Portfolio construction; asset allocation; principal component analysis; hierarchical principal component analysis; hierarchical shrinkage; eigenportfolio risk; Portföljkonstruktion; tillgångsallokering; principalkomponentanalys; hierarkisk principalkomponentanalys; hierarkisk krympning; egenportföljrisk;

    Sammanfattning : With an increasingly globalised market and growing asset universe, estimating the market covariance matrix becomes even more challenging. In recent years, there has been an extensive development of methods aimed at mitigating these issues. LÄS MER

  4. 23. Development and Optimization of Near-infrared spectroscopy

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Amanda Hahlin; [2023]
    Nyckelord :Near-infrared spectroscopy; NIRS; Textile sorting; Principal component analysis; PCA; Post-consumer end-of-life textiles;

    Sammanfattning : With the growing demand for sustainable options, the existing sorting capacities are limiting the potential for fiber-to-fiber recycling. With the help of near-infrared spectroscopy (NIRS), automated sorting of textiles with high accuracy is possible due to the easy access for polymer identification. LÄS MER

  5. 24. Personal Carbon Allowances from a Legal Perspective

    Magister-uppsats, Stockholms universitet/Stockholms miljörättscentrum (SMC)

    Författare :Mona Schumny; [2023]
    Nyckelord :Personal Carbon Allowances; Carbon Accounting; Carbon Footprint; Climate Change; Paris Agreement;

    Sammanfattning : To reach the Paris Agreement targets, the remaining carbon budget is about 2.3 tons of CO2e per person per year. However, current per capita emissions exceed the target, with a global average carbon footprint of 4.81 tons. LÄS MER

  7. 25. Public Domain Intelligence Tests: Psychometric properties of the Cog15 and ICAR16 cognitive ability scales

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Dagný Kristjánsdóttir; Aya Zaiter; [2023]
    Nyckelord :general intelligence; intelligence testing; public domain; CFA; PCA; Social Sciences;

    Sammanfattning : The current paper aims to explore the psychometric properties of two public domain cognitive ability scales, Cog15 and ICAR16, and investigate how well they each capture the g-factor in a Swedish sample (N = 428). The motivation for choosing these aims is that public domain, free, and easily accessible intelligence tests are needed for measuring the g-factor. LÄS MER
