1. 1. 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

3. 2. Improving Availability of the Pelletization Process

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Emil Andreasson; Pontus Åhman; [2022]
   Nyckelord :Availability; Predictive Maintenance; Pelletization; Statistical Process Control; Refractory Material; DMAIC;

   Sammanfattning : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. LÄS MER

4. 3. The Impact of Swedish Public Finance Factors on the Local Real Estate Market : Based on the GMM PVAR Approach

   Master-uppsats, KTH/Fastighetsföretagande och finansiella system

   Författare :Jiayu Zhang; [2022]

   Sammanfattning : Real estate market prices have proven to be influenced by many driving factors. As suggested by Tiebout's (1956) model, the level of public services was believed to influence people's decision to move geographically, which was called "voting with their feet". LÄS MER

5. 4. 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]

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

7. 5. 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
