2. 1. Usable Firewall Rule Sets

   Author : Artem Voronkov; Stefan Lindskog; Kami Vaniea; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Network Security; Usable Security; Firewall Configuration; Systematic Literature Review; Usability Metrics; User Studies; Computer Science; Datavetenskap;

   Abstract : Correct functioning is the most important requirement for any system. Nowadays there are a lot of threats to computer systems that undermine confidence in them and, as a result, force a user to abandon their use. Hence, a system cannot be trusted if there is no proper security provided. READ MORE

4. 2. Modelling Phone-Level Pronunciation in Discourse Context

   Author : Per-Anders Jande; Rolf Carlson; Merle Horne; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pronunciation modelling; Pronunciation variation; Discourse-context; Phone-level variation; Central standard Swedish; Spoken language annotation; Data-driven methods; Machine learning; Decision trees; Pronunciation lexicon development; Machine-readable lexicon; Phonology; Discourse; Lexicon; Language technology; Språkteknologi;

   Abstract : Analytic knowledge about the systematic variation in a language has an important place in the description of the language. Such knowledge is interesting e.g. in the language teaching domain, as a background for various types of linguistic studies, and in the development of more dynamic speech technology applications.

5. 3. Laser Sheet Imaging and Image Analysis for Combustion Research

   Author : Rafeef Abu-Gharbieh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear diffusion filtering; optically dense sprays; curve evolution propagation; image sequence analysis; laser induced fluorescence; geodesic paths; level sets; LIF; optical density; spray characterization; flame propagation; laser; particle image velocimetry; spectroscopy; combustion engines; spray diagnostics; Mie scattering; flame fronts; laser attenuation; tracking; combustion diagnostics; curve matching; combustion; laser sheet imaging; PIV; time resolved imaging; segmentation;

   Abstract : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

6. 4. Efficient Methods for Direct Volume Rendering of Large Data Sets

   Author : Patric Ljung; Anders Ynnerman; Thomas Ertl; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Graphics; Scientific Visualization; Medical Imaging; Volume Rendering; Raycasting; Transfer Functions; Level-of-detail; Fuzzy Classification; Virtual Autopsies; Computer science; Datavetenskap;

   Abstract : Direct Volume Rendering (DVR) is a technique for creating images directly from a representation of a function defined over a three-dimensional domain. The technique has many application fields, such as scientific visualization and medical imaging. READ MORE

7. 5. Sparse Representations for Medium Level Vision

   Author : Per-Erik Forssén; Gösta Granlund; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : In this thesis a new type of representation for medium level vision operations is explored. We focus on representations that are sparse and monopolar. The word sparse signifies that information in the feature sets used is not necessarily present at all points. On the contrary, most features will be inactive. READ MORE
