  2. 11. Simulation based design : structural optimization at early design stages

    Author : Marcus Redhe; Linköpings universitet; []
    Keywords : ;

    Abstract : The aim of this thesis is to evaluate and develop different modelling tools which can be used in the vehicle crashworthiness design process. These tools will improve the understanding of the vehicle behaviour and thus improve the crashworthiness of the vehicle. READ MORE

  4. 12. Aspects of oral implant technology and osseointegration

    Author : Rainde Naiara Rezende de Jesus; Malmö universitet; []

    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.

  5. 13. Electric Fields for Surface Design and Chemical Analysis

    Author : Christian Ulrich; Fredrik Björefors; Ingemar Lundström; Tautgirdas Ruzgas; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electric fields; Surface design; Chemical analysis; Bipolar electrodes; Impedance spectroscopy; Electrochemistry; Elektrokemi; Chemical physics; Kemisk fysik; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : This thesis deals with the use of electric fields for evaluation and control of chemical systems. An electric field can result in the flow of charge across an interface between a metal and a solution, by means of chemical reactions. This interplay between electricity and chemistry, i.e. READ MORE

  6. 14. Cycle paths’ degradation processes and surface condition assessment

    Author : Martin Larsson; Sigurdur Erlingsson; Anna Niska; Inge Hoff; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction design; cycle paths; degradation; distress modes; maintenance; municipalities; survey; cycling comfort; road surface measurements; surface evenness; surface texture; Building Materials; Byggnadsmaterial;

    Abstract : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. READ MORE

  7. 15. Design of Microstructures in Thermal Barrier Coatings : A Modelling Approach

    Author : Mohit Kumar Gupta; Per Nylén; Robert Vaβen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal barrier coatings; microstructure; thermal conductivity; Young‘s modulus; lifetime; finite element modelling; design; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Plasma sprayed Thermal Barrier Coating systems (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. The material that is most commonly used in these applications is Yttria Stabilized Zirconia (YSZ) because of this ceramic’s favourable properties, such as low thermal conductivity, phase stability to high temperature, and good erosion resistance.
