1. 1. The Significance of Things: Affective User-Artefact relations

   Författare :Viktor Hjort af Ornäs; Viktor Hiort af Ornäs; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; User experience; User-centred design; Significant consequences; Significant use; Significant things; User-centred desig; Technology; Teknik; User Centred Product Design; Användarcentrerad produktdesign;

   Sammanfattning : Products help people act, but also thrill, excite, and elicit fear, joy and anger. Artefacts are a natural part of people’s everyday lives, sometimes associated with values, dreams and aspirations. While traditional user-centred approaches have focused on efficiency and effectiveness of use, injury prevention etc. LÄS MER

3. 2. Fungal degradation patterns and toxicity of furfurylated wood

   Författare :Annica Pilgård; Chalmers University of Technology; []
   Nyckelord :Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

   Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER

4. 3. User Centered Design Methods must also be User Centered: A Single Voice from the Field. A Study of User Centered Design in Practice

   Författare :Erik Styhr Petersen; Chalmers University of Technology; []
   Nyckelord :SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES; User Centered Design; Reflective Practice; Usability; Validity; Autoethnography;

   Sammanfattning : The present study concerns itself with the usability of the user centered design methodology, as this is defined by ISO 9241-210 (ISO9241-210, 2009) and other international standards: “[usability is the] extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use” (authors emphasis) (ISO9241-11, 1998; ISO9241-210, 2009, p. 3; ISO13407, 1999, p.

5. 4. Towards Fully Optimized BICM Transmissions

   Författare :Alex Alvarado; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binary reflected Gray code; iterative decoding; pulse amplitude modulation; convolutional codes; trellis-coded modulation; coded modulation; Bit-interleaved coded modulation; quadrature amplitude modulation; hierarchical constellations; interleaver design;

   Sammanfattning : Bit-interleaved coded modulation (BICM) was introduced in 1992 as a new coded modulation (CM) scheme particularly well suited for fading channels and is nowadays considered the de facto CM scheme in wireless standards (HSPA, IEEE 802.11a/g/n, DVB-T2/S2/C2, etc.). LÄS MER

7. 5. A Conceptual Model for Analysis of Automation Usability Problems in Control Room Settings

   Författare :Jonas Andersson; Chalmers University of Technology; []
   Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Human-machine systems; control rooms; cognitive systems engineering; nuclear power; levels of automation; usability problems;

   Sammanfattning : The focus of this licentiate thesis lies on the problems that can emerge when humans and advanced control systems work together in control room environments. In the nuclear domain, automation is used extensively and it is important to maintain safe and efficient operations. LÄS MER
