  2. 1. Dating Divergence Times in Phylogenies

    Author : Cajsa Lisa Anderson; Kåre Bremer; Katleen M. Pryer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; systematic biology; divergence time; nonprametric rate smoothing; Bayesian; multidivtime; eudicots; Neoaves; monocots; dating; molecular clock; relaxed clock; age constraint; fossil; calibration; PATHd8; penalized likelihood; Biology; Biologi;

    Abstract : 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. READ MORE

  4. 2. Securing Clock Synchronization in Industrial Heterogeneous Networks

    Author : Elena Lisova; Mats Björkman; Christian Rohner; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : 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. READ MORE

  5. 3. Continuous-Time Delta-Sigma Modulators for Ultra-Low-Power Radios

    Author : Dejan Radjen; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Delta-Sigma; continuous-time; analog-to-digital; ultra-low-power; clock jitter; single operational amplifier; SAR quantizer;

    Abstract : 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. READ MORE

  6. 4. Probabilistic Reconciliation Analysis for Genes and Pseudogenes

    Author : Owais Mahmudi; Jens Lagergren; Cedric Chauve; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Evolution; Reconciliation Analysis; Bayesian Inference; Datalogi; Computer Science;

    Abstract : 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. READ MORE

  7. 5. Marsupial Mitogenomics

    Author : Maria Nilsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; Biologi; Biology; divergence times; K T-boundary; phylogenetic reconstruction; Ameridelphia; Australidelphia; Notoryctes; Dromiciops; Marsupialia; mitochondrial genomes; cytogenetics; Genetik; cytogenetik;

    Abstract : 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. READ MORE
