    Nyckelord :Delaktighet; ersoncentrerad vård; postoperativ smärtlindring; trådlös övervakning; patientkontrollerad analgesi;

    Sammanfattning : Background: Analgesia is something nurse anesthetists tackle daily. Different approaches to address the problem exist: the concept of an Acute Pain Service team, multimodal analgesia and patient-controlled analgesia (PCA). LÄS MER

  2. 2. The driving forces of Venture Capital funding in Sweden - A longitudinal study of the determinants and principal components of Venture Capital funding in Sweden from 2001 to 2020

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Ludvig Streng; Mikael Örneblad; [2021-07-06]
    Nyckelord :Venture capital; funding; driving forces; Sweden; determinants; regression; OLS; stock market; interest; gdp growth; corporate tax; patent applications; innovation; labor market rigidity; principal component analysis; PCA;

    Sammanfattning : This thesis analyses the driving forces of Venture Capital (VC) funding in Sweden over theyears 2001 - 2020. The driving forces of VC funding is an essential piece in understandinghow well the Swedish VC industry works and fulfills its purpose in the economy. Thisknowledge is missing in the literature.

De olika metoderna är artificiella neurala nätverk och funktionellprincipalkomponentanalys och principalkomponentanalys. För de neurala nätverken har vi tvåtyper: CNN och FNN. LÄS MER

  4. 4. Principal Component Analysis and the Cross-Sectional Variation of Returns

    Kandidat-uppsats,

    Författare :Armin Ramovic; Mikael Åkerman; [2021-06-23]
    Nyckelord :Principal Component Analysis; PCA; principal components; cross-sectional variation of returns; risk premia; asset pricing; demensionality reduction; risk factors; machine learning;

    Sammanfattning : We utilize Principal Component Analysis (PCA), a dimensionality reduction technique, on a set of 142 risk factors, including macroeconomic factors, proposed in financial literature to construct factor models with high explanatory powers when analysing the cross-sectional variation of portfolio returns. We apply a Fama and Macbeth (1973) two-pass regression to estimate risk premia commanded by our principal components. LÄS MER

  5. 5. Anomaly Detection in Log Files Using Machine Learning Techniques

    Magister-uppsats, Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Författare :Lakshmi Geethanjali Mandagondi; [2021]
    Nyckelord :Anomaly Detection; Log Files; Machine Learning; Clustering; Outlier Detection;

    Sammanfattning : Context: Log files are produced in most larger computer systems today which contain highly valuable information about the behavior of the system and thus they are consulted fairly often in order to analyze behavioral aspects of the system. Because of the very high number of log entries produced in some systems, it is however extremely difficult to seek out relevant information in these files. LÄS MER
