2. 1. Selected Topics in Continuum Percolation : Phase Transitions, Cover Times and Random Fractals

   Author : Filipe Mussini; Erik I. Broman; Hermine Biermé; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson point process; Percolation; Boolean model; Quasi-isometries; Cover times; Poisson cylinder process; Ellipsoid process; Phase transition; Random fractals; Mathematics; Matematik;

   Abstract : This thesis consists of an introduction and three research papers. The subject is probability theory and in particular concerns the topics of percolation, cover times and random fractals.Paper I deals with the Poisson Boolean model in locally compact Polish metric spaces. READ MORE

4. 2. 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

5. 3. High Temperature Fatigue Crack Growth in a Ni-based Superalloy : Modelling Including the Interaction of Dwell Times

   Author : Erik Storgärds; Kjell Simonsson; Johan Moverare; Tomas Månsson; Bo Alfredsson; Linköpings universitet; []

   Abstract : Safe life of gas turbines is always of major concern for manufacturers in order to ensure passenger safety and stable continuous power output. An increasing amount of resources have been put into research and development to assure that all safety aspects are covered in the design of new turbines and to ensure that enough frequent service intervals are scheduled to avoid complications.

6. 4. Developing Academic Literacies in Times of Change : Scaffolding Literacies Acquisition with the Curriculum and ICT in Rwandan Tertiary Education

   Author : Charles Karoro Muhirwe; Ingrid Andersson; Nigel John Musk; Martin Stigmar; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Academic literacies; English for Specific Purposes ESP ; scaffolding; curriculum embedment; ICT; tertiary education; Rwanda; Academic literacies; allmän engelska och engelskt fackspråk; stödjande redskap; integrerade läroplaner; IKT; högre utbildning; Rwanda;

   Abstract : Inspired by the Bologna Process and other globalising influences from modern higher education, and driven by policy reform for national development after the ravages of the 1994 conflict and genocide, Rwanda’s tertiary education has embarked on a number of policy reform for national development after the ravages of the 1994 conflict and genocide, Rwanda’s tertiary education has embarked on a number of policy reforms that have ushered in expectations, requirements and demands that call for both reinvigorated and new academic literacies in undergraduate study since 2007. With its aim of producing a highly skilled human resource as a panacea for Rwanda’s social and economic development deficits, the tertiary education curriculum is more than never before focused on outcomes that are linked to further education and the labour market.

7. 5. On Estimating Topology and Divergence Times in Phylogenetics

   Author : Bodil Svennblad; Allan Gut; Tom Britton; Thore Egeland; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Phylogenetics; Divergence Time; Likelihood based methods; Non-informative prior; bootstrap support; Matematisk statistik;

   Abstract : This PhD thesis consists of an introduction and five papers, dealing with statistical methods in phylogenetics.A phylogenetic tree describes the evolutionary relationships among species assuming that they share a common ancestor and that evolution takes place in a tree like manner.
