2. 1. Aspects of oral implant technology and osseointegration

   Author : Rainde Naiara Rezende de Jesus; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

   Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

4. 2. Towards Surface Engineering

   Author : Bengt-Göran Rosen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The purpose of this dissertation is to explore a route towards surface engineering both by the introduction of a conceptual framework called Interactive Surface Modelling (ISM) and by the actual application of the concept on two functional surfaces of importance to the automotive industry: cylinder liners for engines and leather imitation surfaces for the interior of cars. The results are presented in six separate but related papers concerning the construction of the ISM system shell and the use of modern technology to explore and represent the functional knowledge relevant to the specification of surface properties.

5. 3. An Insight into the Critical Role of Microstructure and Surface Preparation on Localized Conversion Coating Deposition on Cast Al Alloys

   Author : Salil Sainis; Caterina Zanella; Ehsan Ghassemali; Marjorie Olivier; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloys; cast Al-Si alloys; conversion coating treatment; cerium; localized deposition; surface preparation; microstructure; SEM; FIB-SEM; AFM-SKPFM; Aluminiumlegeringar; gjutna Al-Si legeringar; Cerium; lokal deposition; omvandlingsbeläggningsbehandling; förbehandling av yta; mikrostruktur; SEM; FIB-SEM; AFM-SKPFM;

   Abstract : The spontaneous cerium conversion coating formation over aluminium alloys is affected by the chemical process conditions, the surface preparation prior to conversion treatment and the microstructure of the underlying alloy. Most research performed until now focus only on the former whereas the influence of the latter two is poorly understood. READ MORE

6. 4. Metamodel based multi-objective optimization

   Author : Kaveh Amouzgar; Peter Hansbo; Niclas Strömberg; Kent Salomonsson; Sunith Bandaru; Jönköping University; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-objective optimization; strength Pareto evolutionary algorithm; SPEA2; metamodel; surrogate model; response surface; radial basis functions; RBF;

   Abstract : As a result of the increase in accessibility of computational resources and the increase in the power of the computers during the last two decades, designers are able to create computer models to simulate the behavior of a complex products. To address global competitiveness, companies are forced to optimize their designs and products. READ MORE

7. 5. Working with the Fogbow : Design and Reconfiguration of services and Participation in E-Government

   Author : Annelie Ekelin; Högskolan i Kalmar; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information Technology; e-government; e-democracy; Technoscience Studies; Informatics; 24-timmarsmyndigheten; serviceutveckling inom offentlig sektor; medborgarperspektiv; Informatik;

   Abstract : This thesis is about the metaphors of the rainbow and the fogbow, investigations and evaluations, public Internet monitors, writing women, reflections and discussions about politics, design and democracy. It is also about the ongoing re-structuring of participation in service design within the development of E-Government. READ MORE
