  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

  2. 2. A revised perspective on Disruptive Innovation - Exploring Value, Networks and Business models

    Författare :Christian Sandström; Chalmers University of Technology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Disruptive innovation; discontinuous; Facit; network; business model; value; Hasselblad;

    Sammanfattning : The concept of disruptive innovation has received much attention in recent years. These innovations can be defined as offering an initially lower performance while at the same time bringing some new attributes to the market. LÄS MER

  3. 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.

  4. 4. Coded Modulation Techniques in Fiber-Optical Communications

    Författare :Lotfollah Beygi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Today's high demand for increasing the data transmission rate motivates a great challenge to improve the spectral efficiency of fiber-optical channels. In order to achieve a higher spectral efficiency, exploiting an advanced coded modulation scheme is inevitable. LÄS MER

  5. 5. Surface Modifications and Applications of Aqueous Silica Sols

    Författare :Peter Greenwood; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; applications; Surface modification; aqueous; silica sol; silane; colloidal silica; titania;

    Sammanfattning : Methods of modifying the surface of the particles of colloidal silica were developed and the effects of surface modification on the properties of colloidal silica were studied.Gamma-glycidoxypropyltrimethoxysilane (GPTMS) readily reacts with water to yield a hydrolysed silane that reacts readily with the silica surface.
