2. 1. Wavelet Galerkin methods for elastic multibody systems with unilateral contact constraints

   Author : José Díaz López; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Elastic MBS; Contact; Unilateral Contraints; Wavelet; DAE; Daubechies; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

   Abstract : In this thesis we investigate the applicability of wavelets to simulate the time behavior of elastic multibody systems (MBS) with contact constraints. For this end, a wavelet element method (WEM) was implemented, exploiting the special structure of the coupled ODE/PDE equations that govern elastic MBS. READ MORE

4. 2. Cam Roller Contact : Surfaces and Tribology

   Author : Frédéric Cabanettes; Bengt-Göran Rosén; Ulf Olofsson; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wear reduction; camshaft; roller; surface topography; relocation; elasto plastic rough contact; elasto hydrodynamic lubrication; Mechanical engineering; Maskinteknik;

   Abstract : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. In the valve train, mechanical components such as camshafts and rollers are defined by specifications including more and more constraints concerning their ability to face wear thus prolonging lifetime.

5. 3. Numerical simulation of thermomechanically coupled transient rolling contact - An arbitrary Lagrangian-Eulerian approach

   Author : Andreas Draganis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical coupling; finite element method; transient analysis; arbitrary Lagrangian--Eulerian; rolling contact; frictional contact;

   Abstract : Numerical simulation of rolling contact serves as an important complement to laboratory and full-scale testing in the endeavour to further the understanding of related physical mechanisms, e.g. the influence of friction on the rolling motion, the thermomechanical interaction, damage phenomena and related modes of failure.

7. 5. Islands of Togetherness : Rewriting Context Analysis

   Author : Minna Räsänen; Ann Lantz; Per-Anders Forstorp; James M. Nyce; Paul Dourish; KTH; []
   Keywords : HUMANIORA; HUMANITIES; Human-Computer Interaction; call-centre organization; ethnography; togetherness; socio-cultural context; Technology and culture; Teknik och kultur;

   Abstract : A continuing debate within Human-Computer Interaction (HCI) research is how to elucidate, improve, and optimize the relationship between social context and technology use. Social context is conventionally understood as immediate use context while an understanding informed by social science suggests a wider scope, involving actors and structures. READ MORE
