1. Dating Divergence Times in Phylogenies
Sammanfattning : This thesis concerns different aspects of dating divergence times in phylogenetic trees, using molecular data and multiple fossil age constraints.Datings of phylogenetically basal eudicots, monocots and modern birds (Neoaves) are presented. Large phylograms and multiple fossil constraints were used in all these studies. LÄS MER
2. Securing Clock Synchronization in Industrial Heterogeneous Networks
Sammanfattning : Today, wireless solutions for industrial networks are becoming more and more appealing since they increase flexibility and enable the use of additional wireless sensors, but also bring such advantages as mobility and weight reduction. Wired networks, on the other hand, are reliable and, more importantly, already existing in most distributed control loops. LÄS MER
3. Continuous-Time Delta-Sigma Modulators for Ultra-Low-Power Radios
Sammanfattning : The modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. LÄS MER
4. Probabilistic Reconciliation Analysis for Genes and Pseudogenes
Sammanfattning : Phylogeneticists have studied the evolution of life from single celled organisms to the astonishing biodiversity around us for a long time now. The relationship between species is often expressed as a binary tree - the tree of life. LÄS MER
5. Marsupial Mitogenomics
Sammanfattning : The relationships of the mammalian infraclass Marsupialia have been investigated by phylogenetic analysis using completely sequenced mitochondrial genomes. The organisation and structure of the marsupial mitochondrial genomes deviates from the general mammalian structure. LÄS MER
