1. Hasse invariants on Shimura varieties and moduli of G-bundles
Sammanfattning : This thesis consists of four papers, referred to in the text as Paper I, II, III and IV, respectively. In Paper I and II, we study the classical Hasse invariant on the geometric special fiber of several Hodge and abelian-type Shimura varieties. LÄS MER
2. Mathematical Foundations of Equivariant Neural Networks
Sammanfattning : Deep learning has revolutionized industry and academic research. Over the past decade, neural networks have been used to solve a multitude of previously unsolved problems and to significantly improve the state of the art on other tasks. However, training a neural network typically requires large amounts of data and computational resources. LÄS MER
3. ATMP Process : Improved Energy Efficiency in TMP Refining Utilizing Selective Wood Disintegration and Targeted Application of Chemicals
Sammanfattning : This thesis is focused on the novel wood chip refining process called AdvancedThermomechanical Pulp (ATMP) refining. ATMP consists of mechanical pretreatmentof chips in Impressafiner and Fiberizer prior to first stage refining atincreased intensity. LÄS MER
4. Ga-actions on Complex Affine Threefolds
Sammanfattning : This thesis consists of two papers and a summary. The papers both deal with affine algebraic complex varieties, and in particular such varieties in dimension three that have a non-trivial action of one of the one-dimensional algebraic groups Ga := (C, +) and Gm := (C*, ·). LÄS MER
5. On transplantation of fetal ventral mesencephalon with focus on dopaminergic nerve fiber formation
Sammanfattning : Poor cell survival and striatal reinnervation are two of the postulated limiting factors of fetal ventral mesencephalic (VM) grafting in Parkinson's disease. It has, however, been reported that an increased survival of VM dopaminergic neurons does not correlate with an enhanced target innervation. LÄS MER
