   Author : Hussein Al-Hussein; [2023]
   Keywords : Alpha-iron; Chromium carbide; Cr7C3; Fe; Theoretical investigation; Orthorhombic; X-ray diffraction pattern; XRD; VASP; VESTA; Body-centered-cubic; Ferrite; Density functional theory; DFT; Surface relaxation; Simulation; Calculation; Energy relaxation; Slab models; Coherency; Surface energy; Interfacial energy; Alfa-järn; Kromkarbid; Cr7C3; Fe; Teoretisk undersökning; Ortorombisk; Röntgendiffraktion; XRD; VASP; VESTA; Ytenergi; Koherent; Simulering; Beräkning; Järnkarbid; DFT; Täthetsfunktionalanalys;

   Abstract : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). READ MORE

3. 2. A Framework to Model Bond Liquidity

   University essay from KTH/Matematik (Avd.)

   Author : Alan Issa; [2023]
   Keywords : Bonds; liquidity; order book; stochastic process; stationarity; gamma distribution.; Obligationer; likviditet; orderbok; stokastisk process; stationaritet; gamma distribution.;

   Abstract : The liquidity of financial assets can be studied in various different ways. In this thesis, liquidity is defined as the cost and time required to liquidate a position. READ MORE

4. 3. Random matrix theory in machine learning

   University essay from KTH/Matematik (Avd.)

   Author : Lina Leopold; [2023]
   Keywords : Mathematics; mathematical statistics; machine learning; random matrix theory; neural networks; Matematik; matematisk statistik; maskininlärning; slumpmatristeori; neuronnätverk;

   Abstract : In this thesis, we review some applications of random matrix theory in machine learning and theoretical deep learning. More specifically, we review data modelling in the regime of numerous and large dimensional data, a method for estimating covariance matrix distances in the aforementioned regime, as well as an asymptotic analysis of a simple neural network model in the limit where the number of neurons is large and the data is both numerous and large dimensional.

   Abstract : Collateral management has become an increasingly valuable aspect of credit risk. Managing collaterals and constructing accurate models for decision making can give any lender a competitive advantage and decrease overall risks. READ MORE

6. 5. Farm-based education : can farms and farm animals contribute to learning in accordance with the school curriculum and syllabi?

   University essay from SLU/Dept. of People and Society

   Author : Malin Larsson; [2022]
   Keywords : farm-based education; educational farms; experiential learning; embodiment; embodied learning; outdoor education; animal-assisted education;

   Abstract : There seems to be something missing in the modern school. An increasing number of students face difficulties in the traditional classroom setting, some cannot attend school at all, and a worrying number of students fail to leave school with approved grades, with potentially detrimental effects on their future lives.
