21. Stochastic modelling and analysis of early mouse development
Sammanfattning : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. LÄS MER
22. Dielectric Relaxation in Dielectric Mixtures
Sammanfattning : In this thesis dielectric properties of both ideal composite structures and polymeric composite materials were investigated. Numerical calculations were performed to simulate frequency response of interfacial polarization using the finite element method in two dimensions. LÄS MER
23. Evolving intelligence : Overcoming challenges for Evolutionary Deep Learning
Sammanfattning : Deep Learning (DL) has achieved remarkable results in both academic and industrial fields over the last few years. However, DL models are often hard to design and require proper selection of features and tuning of hyper-parameters to achieve high performance. These selections are tedious for human experts and require substantial time and resources. LÄS MER
24. Studies in the Geometry of Quantum Measurements
Sammanfattning : Quantum information studies quantum systems from the perspective of information theory: how much information can be stored in them, how much the information can be compressed, how it can be transmitted. Symmetric informationally-Complete POVMs are measurements that are well-suited for reading out the information in a system; they can be used to reconstruct the state of a quantum system without ambiguity and with minimum redundancy.

25. Anisotropy, disorder and frustration in magnetic nanoparticle systems and spin glasses
Sammanfattning : Magnetic properties of nanoparticle systems and spin glasses have been investigated theoretically, and experimentally by squid magnetometry.Two model three-dimensional spin glasses have been studied: a long-range Ag(11 at% Mn) Heisenberg spin glass and a short-range Fe0.5Mn0.5TiO3 Ising spin glass.
