2. 1. Selected Topics in Mathematical Modelling: Machine Learning and Tugs-of-War

   Author : Carmina Fjellström; Kaj Nyström; Andrea Pascucci; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machine learning; Neural networks; LSTM; Financial forecasting; Time series analysis; Stochastic gradient descent; Diffusion map; Dimension reduction; Tug-of-war games; Fractional heat operator; Mean value property; Infinity fractional heat operators; Dynamic programming principle; p-Laplacian; Infinity Laplacian; Kolmogorov equation; Stochastic games; Viscosity solutions; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

   Abstract : This thesis concerns selected topics in mathematical modelling, namely in machine learning and stochastic games called tugs-of-war. It consists of four scientific articles. The first and second are about machine learning topics, while the third and fourth articles are about tug-of-war games. READ MORE

4. 2. Reproducing kernels and potential theory for the Bergman spaces

   Author : Yolanda Perdomo Gallipoli; Matematikcentrum; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; weighted biharmonic Green function Gaussian curvature; Naturvetenskap; harmonic compensator; Natural science; weighted super-biharmonic function; potential metric; mean value property; weighted Bergman kernel;

   Abstract : The role of weighted biharmonic Green functions in weighted Bergman spaces was first studied in the beginning of the 50's by Paul Garabedian. In 1951 he showed that they are closely related to reproducing kernel functions of weighted Bergman spaces. READ MORE

6. 4. Experimental Studies of Deformation Structures in Stainless Steels using EBSD

   Author : Karin Yvell; Annika Borgenstam; Peter Hedström; Göran Engberg; Johan Moverare; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Austenitic stainless steels; Duplex stainless steel; In situ tensile test; Grain boundaries; Grain rotation; Grain size distribution; Texture; Strain hardening; Structure-property relationship; High strain rate; Wire rod rolling; Roll forming; Steel Forming and Surface Engineering; Stålformning och ytteknik;

   Abstract : In this thesis, the focus has been the study of deformation structures in stainless steels by using electron backscatter diffraction (EBSD). Via increased knowledge of the evolution of the substructure during deformation, the design and control of the manufacturing process can be improved. READ MORE

7. 5. Vertical Trade

   Author : Anna Andersson; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Trade in intermediate inputs; fragmentation; private standards; rules of origin; duration;

   Abstract : This thesis consists of three separate papers. They are all empirical papers that examine how fragmentation of production processes and global value chains have affected international trade patterns. The first paper focuses on how private standards in the increasingly geographically fragmented food sector affect firm-import behaviour. READ MORE
