1. 1. Managing discontinuous changes in complex products : Cases involving the development and market introduction of heavy hybrid-electric buses

   Författare :Dedy Sushandoyo; Christian Berggren; Thomas Magnusson; Mats Magnusson; Linköpings universitet; []
   Nyckelord :Discontinuous changes; complex products; discontinuous innovations; technology selections; development and market introduction; heavy hybrid-electric vehicles; the heavy vehicle industry; Diskontinuerliga förändringar; komplexa produkter; diskontinuerliga innovationer; teknologival; utveckling och marknadsintroduktion; tunga eldrivna hybridbussar; tunga bilindustrin;

   Sammanfattning : This is a study about managing the development of discontinuous changes in complex products characterised by integration of a significant amount of new technologies and firms’ existing technologies and market introduction of such products. In particular, this study analyses how firms’ technology selections influence the conditions for the firms to manage such development and market introduction. LÄS MER

3. 2. Perspectives on Manufacturing Development - Discontinuous Change and Continuous Improvement

   Författare :Anders Berger; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; change theory; performance; Continuous Improvement; large-scale renewal; practice; balance; multifunctional work groups; discontinuous change; Sweden; manufacturing development;

   Sammanfattning : The dissertation deals with the management of planned change and development efforts in manufacturing environments. Two models for improving and sustaining operational performance (technical, economic and social) are presented: the discontinuous change model and the continuous improvement model. LÄS MER

4. 3. On discontinuous Galerkin multiscale methods

   Författare :Daniel Elfverson; Axel Målqvist; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Sammanfattning : In this thesis a new multiscale method, the discontinuous Galerkin multiscale method, is proposed. The method uses localized fine scale computations to correct a global coarse scale equation and thereby takes the fine scale features into account. LÄS MER

5. 4. Phase field modeling of precipitation reactions in miscibility gap systems

   Författare :Deepjyoti Mukherjee; Joakim Odqvist; Henrik Larsson; Benoît Appolaire; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precipitation; Discontinuous; Diffusion; Boundary; Phase-field; Miscibility-gap; Cemented carbides; Binary alloys; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : As a backbone to the cutting tools and rock drilling industry, cemented carbides have been used widely due to their high hardness and wear resistance. Most commercially used cemented carbides contain a hard phase made of Tungsten carbide (WC) and a binder phase which is generally ductile. LÄS MER

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

   Författare :Christian Sandström; Chalmers tekniska högskola; []
   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
