1. 1. Computational problems in evolution : Multiple alignment, genome rearrangements, and tree reconstruction

   Författare :Isaac Elias; Jens Lagergren; Lior Pachter; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distance Methods; Tree reconstruction; Sorting by Transpositions; multiple alignment; ancestral sequences; Computer science; Datavetenskap;

   Sammanfattning : Reconstructing the evolutionary history of a set of species is a fundamental problem in biology. This thesis concerns computational problems that arise in different settings and stages of phylogenetic tree reconstruction, but also in other contexts. LÄS MER

3. 2. Evolutionary Approaches to Sequence Alignment

   Författare :Marcin Bogusz; Simon Whelan; Jeffrey Thorne; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; multiple sequence alignment; pair hidden Markov models; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Molecular evolutionary biology allows us to look into the past by analyzing sequences of amino acids or nucleotides. These analyses can be very complex, often involving advanced statistical models of sequence evolution to construct phylogenetic trees, study the patterns of natural selection and perform a number of other evolutionary studies.

4. 3. Interpretation and Alignment of 2D Indoor Maps : Towards a Heterogeneous Map Representation

   Författare :Saeed Gholami Shahbandi; Björn Åstrand; Roland Philippsen; Antanas Verikas; Patric Jensfelt; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Mobile Robots; Autonomous Robots; Robot Perception; Robotic Mapping; Map Interpretation; Semantic Mapping; Place Categorization; Place Labeling; Semantic Annotation; Map Alignment; Region Segmentation; Region Decomposition; Map Representation; Heterogeneous Representation;

   Sammanfattning : Mobile robots are increasingly being used in automation solutions with notable examples in service robots, such as home-care, and warehouses. Autonomy of mobile robots is particularly challenging, since their work space is not deterministic, known a priori, or fully predictable. LÄS MER

5. 4. Fostering User Involvement in Ontology Alignment and Alignment Evaluation

   Författare :Valentina Ivanova; Patrick Lambrix; Nahid Shahmehri; Fabien Gandon; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Knowledge representation; ontology; ontology engineering; ontology debugging; ontology matching; ontology matching evaluation; user interfaces; human-computer interaction; large and high-resolution displays;

   Sammanfattning : The abundance of data at our disposal empowers data-driven applications and decision making. The knowledge captured in the data, however, has not been utilized to full potential, as it is only accessible to human interpretation and data are distributed in heterogeneous repositories. LÄS MER

7. 5. Solving the correspondence problem in analytical chemistry : Automated methods for alignment and quantification of multiple signals

   Författare :Erik Alm; Magnus Åberg; Beata Walczak; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

   Sammanfattning : When applying statistical data analysis techniques to analytical chemical data, all variables must have correspondence over the samples dimension in order for the analysis to generate meaningful results. Peak shifts in NMR and chromatography destroys that correspondence and creates data matrices that have to be aligned before analysis. LÄS MER
