1. 1. 'Getting' it Together In Joint Directed Action

   Författare :Christina Mauléon; Philippe Lorino; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emotion; interpretational-relational; language discourse; Joint Directed Action; meaning making sensemaking; quality sciences; relational landscape; identity; action.;

   Sammanfattning : This thesis is focused upon investigating how come activities in organizations are sometimes not aligned with an objective at hand, be it a project goal, safety, quality or other. When something goes wrong, where are the answers to be found? In the pursuit to examine these questions further, the aim of the thesis has been to investigate meaning making in action as this can increase an understanding of how actors may continuously align their actions, collective and/or individual, with a common goal – this process here being called Joint Directed Action (JDA).

3. 2. Quality-Driven Production of Aggregates in Crushing Plants

   Författare :Magnus Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; breakage; crushing; simulation; modelling; Keywords: aggregate quality; particle shape;

   Sammanfattning : Aggregate quality is of great importance, and in this context it is essential to understand how various process parameters influence the product quality characteristics. Thus, there is a need for aggregate producers to improve their process knowledge. LÄS MER

4. 3. Connected Practice: The Dynamics of Social Interaction in Shared Virtual Environment

   Författare :Maria Spante; Ralph Schroeder; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; time; connected practice.; Shared virtual environments; virtual reality technology; dynamics; social interaction; practice; Informatik;

   Sammanfattning : This thesis investigates the phenomenon of social interaction in shared virtual environments (SVEs), supported by virtual reality (VR) systems over time. SVEs are computer generated 3D graphical spaces where geographically distributed people can meet and interact with each other in a graphical space. LÄS MER

5. 4. Towards Active Car Body Suspension in Railway Vehicles

   Författare :Jessica Fagerlund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; Model reduction; Active suspension; MIMO systems; LQ control;

   Sammanfattning : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. LÄS MER

7. 5. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties

   Författare :Hans Fredriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical resonance; Raman-spectrum; carbon; optical spectrum; HOPG; GC amorphous carbon; oxidation; Nanofabrication;

   Sammanfattning : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.
