2. 1. Adding usability : Methods for modelling, user interface design and evaluation

   Author : Magnus Lif; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Modelling; analysis; design; evaluation; user interface; human computer interaction; system development; usability; utility; methods; workspace; iterative; designer; Materialvetenskap; Materials science; Teknisk materialvetenskap; datavetenskap med inriktning människa-datorinteraktion; Computer Science; human-computer interaction;

   Abstract : Many system development projects fail to provide information systems with high usability. This thesis focuses on how to solve this problem by introducing methods for modelling, user interface design and evaluation. These methods are primarily designed to serve as complements to existing methods for systems development. READ MORE

4. 2. Mining Web Logs to Improve User Experience in Web Search

   Author : Libertad Tansini; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Web log mining; web search; user intent; user recommendation; user modelling;

   Abstract : The World Wide Web continues to grow in size and diversity and this makes it increasinglyhard for users to find valuable information because of heterogeneous form and contentof the documents, little knowledge about the reliability and prestige of the documents anda great deal of redundancy.Usually search engines look for documents that contain specific keywords or phrasesstated by the users as queries.

5. 3. Probabilistic Modelling of Hearing : Speech Recognition and Optimal Audiometry

   Author : Svante Stadler; Arne Leijon; Stefan Stenfelt; KTH; []
   Keywords : auditory models; probabilistic modelling; speech modelling; human speech recognition; hearing aids; cochlear implants; psychoacoustics; diagnostic methods; optimal experiments; audiometry;

   Abstract : Hearing loss afflicts as many as 10\% of our population.Fortunately, technologies designed to alleviate the effects ofhearing loss are improving rapidly, including cochlear implantsand the increasing computing power of digital hearing aids. Thisthesis focuses on theoretically sound methods for improvinghearing aid technology. READ MORE

6. 4. Modelling of Granular Materials

   Author : Aylin Ahadi; Mekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; materialteknik; Materiallära; Material technology; binary mixture model; simulations; material modelling; finite element; granular materials; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Abstract : The aim of this doctoral study is to develop and implement a material model for granular materials. The course of this work was concentrated upon a non-associated plasticity model with yield surface and the flow potential expressed in terms of the mean stress p and the third stress invariants I3.

7. 5. From Conceptual Links to Causal Relations — Physical-Virtual Artefacts in Mixed-Reality Space

   Author : Thomas Pederson; Lars-Erik Janlert; William Buxton; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Människa-dator-interaktion; Human-Computer Interaction; Mixed Reality; Augmented Reality; Ubiquitous Computing; Pervasive Computing; Graspable User Interfaces; Tangible User Interfaces; Wearable Computing; Context Awareness; User Modelling; Interaction Design; Systems Design; Människa-dator-interaktion; Information technology; Informationsteknologi; business data processing; administrativ databehandling;

   Abstract : This thesis presents a set of concepts and a general design approach for designing Mixed Reality environments based on the idea that the physical (real) world and the virtual (digital) world are equally important and share many properties. Focus is on the design of a technology infrastructure intended to relieve people from some of the extra efforts currently needed when performing activities that make heavy use of both worlds.
