2. 1. Incremental Clustering of Source Code : a Machine Learning Approach

   Author : Tobias Olsson; Morgan Ericsson; Sebastian Herold; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machine Learning; Naive Bayes; Source Code Clustering; Incremental Clustering; Software Architecture; Technical Debt; Computer Science; Datavetenskap;

   Abstract : Technical debt at the architectural level is a severe threat to software development projects. Uncontrolled technical debt that is allowed to accumulate will undoubtedly hinder speedy development and maintenance, introduce bugs and problems in the software product, and may ultimately result in the abandonment of the source code.

4. 2. Essays on Distance Based (Non-Euclidean) Tests for Spatial Clustering in Inhomogeneous Populations : Adjusting for the Inhomogeneity through the Distance Used

   Author : Ulla Romild; Johan Lyhagen; Anders Ågren; Jack Cuzick; Uppsala universitet; []
   Keywords : Statistics; Clustering; Spatial Point Pattern; Inhomogeneous Density; Statistik;

   Abstract : This thesis consits of four papers dealing with distance based (non-Euclidean) tests for spatial clustering in inhomogeneous populations. The density adjusted distance (DAD), which considers the underlying density, is defined in the first paper. READ MORE

5. 3. Consensus Algorithms for Trees and Strings

   Author : Jesper Jansson; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerical analysis; computational complexity; Approximation algorithm; labeled tree; lowest common ancestor constraint; maximum agreement subtree; alignment between trees; clustering; Computer science; Hamming metric; systems; control; Datalogi; numerisk analys; system; kontroll;

   Abstract : This thesis studies the computational complexity and polynomial-time approximability of a number of discrete combinatorial optimization problems involving labeled trees and strings. The problems considered have applications to computational molecular biology, pattern matching, and many other areas of computer science. READ MORE

6. 4. On the Size and Shape of Polymers and Polymer Complexes : A Computational and Light Scattering Study

   Author : Tomas Edvinsson; Terence Cosgrove; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Monte Carlo simulations; grafted polymers; shape description; folding complexity; clustering; percolation algorithm; light scattering; end-capped polymers; inclusion complexes; Fysik; Physics; Fysik; Physical Chemistry; Fysikalisk kemi;

   Abstract : Detailed characterization of size and shape of polymers, and development of methods to elucidate the mechanisms behind shape transitions are central issues in this thesis. In particular we characterize grafted polymer chains under confinement in terms of the chain entanglement complexity and mean molecular size. READ MORE

7. 5. Frames of threat and solidarity : Dynamics of media discourse on immigration in Sweden

   Author : Victoria Yantseva; Giangiacomo Bravo; Kostiantyn Kucher; Gergei Farkas; Simon Lindgren; Linnéuniversitetet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi;

   Abstract : This dissertation aims to analyse media discourse about immigration in Sweden in the last decade. To meet this goal, it uses large-scale textual data collected from various media resources, such as mainstream newspapers, social media (Twitter and Facebook) and an online forum. READ MORE
