11. Split Trees, Cuttings and Explosions
Sammanfattning : This thesis is based on four papers investigating properties of split trees and also introducing new methods for studying such trees. Split trees comprise a large class of random trees of logarithmic height and include e.g., binary search trees, m-ary search trees, quadtrees, median of (2k+1)-trees, simplex trees, tries and digital search trees.

12. Spectra and Dynamics of Excitations in Long-Range Correlated Structures
Sammanfattning : Vad karaktäriserar en kristall? Svaret på denna till synes enkla fråga blir kanske att det är en anordning av atomer uppradade i periodiska mönster. Så ordnade strukturer kan studeras genom att det uppträder så kallade Braggtoppar i röntgendiffraktionsmönstret. LÄS MER
13. Genomic signatures in viruses
Sammanfattning : In an age of global pandemics, studying how viruses and their genomes evolve is of great importance. It has previously been found that the genomes of many eukaryotes and prokaryotes have specific preferences for nucleotides, dinucleotides, and codons. LÄS MER
14. Accelerating Monte Carlo methods for Bayesian inference in dynamical models
Sammanfattning : Making decisions and predictions from noisy observations are two important and challenging problems in many areas of society. Some examples of applications are recommendation systems for online shopping and streaming services, connecting genes with certain diseases and modelling climate change. LÄS MER
15. Optimal input design for nonlinear dynamical systems : a graph-theory approach
Sammanfattning : Optimal input design concerns the design of an input sequence to maximize the information retrieved from an experiment. The design of the input sequence is performed by optimizing a cost function related to the intended model application. Several approaches to input design have been proposed, with results mainly on linear models. LÄS MER
