2. 1. Studies in Applied Data Structures

   Author : Kurt Swanson; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Sparse Matrix; Suffix Tree; Roundness; Range searching; Data- och systemvetenskap; computer technology;

   Abstract : The design of efficient data structures is of primary importance in creation of theoretical algorithms as well their more tangible descendants, computer programs. In this dissertation we study computational aspects of data structures and their respective algorithms from a theoretical viewpoint, which are however of direct importance in the implementation of solutions for real-world problems.

4. 2. Stochasticity in Biophysical Systems: Searching, Aging, and Spreading

   Author : Lloyd Sanders; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anomalous diffusion; Single-file; Markov process; Epidemiology; First Passage Time;

   Abstract : The role of stochasticity throughout many biophysical systems is of great importance. From evolution to foraging, from the spreading of viruses to cell fate, all hinge in one way or another on inherent stochasticity. READ MORE

5. 3. Evolutionary and mechanistic aspects of insect host plant preference

   Author : Alexander Schäpers; Niklas Janz; Steven Heard; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; host plant choice; host range; diet breadth; butterfly; oviposition; specialist; generalist; insect-plant interaction; search behavior; olfaction; decision making; evolution; parasite-host interaction; zoologisk ekologi; Animal Ecology;

   Abstract : Plant feeding insects comprise about 25% of all animal species on earth and play an important role in all ecosystems. Although we understand that their association with plants is a key-factor driving the diversification in this group, we still have large gaps in our knowledge of the underlying processes of this relationship.

6. 4. Searching for Gamma Rays from Galaxy Clusters with the Fermi Large Area Telescope : Cosmic Rays and Dark Matter

   Author : Stephan Zimmer; Jan Conrad; Christophe Clement; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; galaxy clusters; gamma rays; cosmic rays; dark matter; fermi-lat; likelihood analysis; joint likelihood;

   Abstract : In this licentiate thesis, I report a search for GeV γ rays towards the location of Galaxy clusters. I mainly discuss the results of a search for cosmic-ray (CR) induced γ-ray emission but also briefly elaborate on a related study, searching for Dark Matter (DM)-induced γ-ray emission from Galaxy clusters.

7. 5. The development and implementation of software for palaeoenvironmental and palaeoclimatological research : the Bugs Coleopteran Ecology Package (BugsCEP)

   Author : Philip Buckland; Roger Engelmark; Geoffrey Lemdahl; Paul Sinclair; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Quaternary geology; environmental archaeology; quaternary science; Coleoptera; beetles; database; environmental reconstructions; climate reconstructions; software; Mutual Climatic Range; MCR; palaeoentomology; Kvartärgeologi; Archaeology; Arkeologi; Archaeology; arkeologi;

   Abstract : This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations.
