1. 16. Konstnärskap i samspel : om skapande arbetsprocesser i myndighetsledda samverkansprojekt

   Författare :Ulrika Florin; Inger Orre; Yvonne Eriksson; Maria Johansson; Mälardalens högskola; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Creative work processes; collaborative projects; sketches; models; presentation; practical knowledge; visual communication; Skapande arbetsprocesser; samverkans projekt; skiss; modell; presentation; praktisk kunskap; visuell kommunikation; Innovation and Design; innovation och design;

   Sammanfattning : Artists in interaction: creation processes in official collaborative projects is a doctoral thesis that explores the creation processes of artists, when the project owner defines the purpose, theme and framework. The area is explored from the artists' perspective and the overall research question deals with the opportunities and obstacles that artists face when working in collaborative projects. LÄS MER

3. 17. Machinability Testing of Materials in Metal Cutting with Focus on Compacted Graphite Iron and Cutting Fluids

   Författare :Varun Nayyar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UTS.; Boring; Drilling; Cutting Fluid; Turning; Milling; Force; Wear; Force; Torque; Compressed air; CGI; Hardness; Tool Life; Material Properties; Chip Microstructure; Tapping;

   Sammanfattning : Due to the stringent demands for lower emission from trucks require better mechanical properties of the material to be used in the engines. Better efficiency necessitates higher peak pressure in the engines and for traditionally used material, Flake Graphite Iron (FGI), the mechanical properties starts to reach the limit of what the material can withstand.

4. 18. Deriving effective forces for mesoscopic particle simulations

   Författare :Johan Nyström; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Coarse graining; Boids; Force covariance; Mori-Zwanzig projection; Dissipative particle dynamics; Force matching; Flocking.;

   Sammanfattning : In the field of molecular simulations, the long-standing aim has been to study mechanisms that cannot easily be observed in experiments or understood in terms of more abstract models. This is hard for systems of mesoscopic size (proteins, membranes etc. LÄS MER

5. 19. Simple Models for Complex Nonequilibrium Problems in Nanoscale Friction and Network Dynamics

   Författare :David Andersson; Astrid de WIjn; Supriya Krishnamurthy; Nicola Manini; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tribology; nanofriction; 2d materials; graphene; image reconstruction; social dynamics; common-pool resource; collective action; simple models; teoretisk fysik; Theoretical Physics;

   Sammanfattning : This doctoral thesis investigates three different topics: How friction evolves in atomically thin layered materials (2D materials); How social dynamics can be used to model grand scale common-pool resource games; Benchmarking of various image reconstruction algorithms in atomic force microscopy experiments. While these topics are diverse, they share being complex out-of-equilibrium systems. LÄS MER

7. 20. Models of magnetism in electrical machines

   Författare :Gustav Mörée; Mats Leijon; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : The magnetic field is a fundamental part of an electrical machine, for establishing the torque and inducing voltages and currents. Then acting as the link between mechanical power and electrical power. This thesis will give a comprehensive study of how magnetism could be modeled. LÄS MER
