2. 21. Human induced pluripotent stem cells in regenerative medicine

   Author : Elias Uhlin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Human induced pluripotent (iPS) cells offer a theoretically inexhaustible cell source for the derivation of any cell type and are a promising tool in regenerative medicine. Cells can be derived from the recipients own tissue or from pre-selected HLA-matched donors. READ MORE

4. 22. A Panel Method for Supersonic Flow

   Author : David Pettersson; Per Weinerfeldt; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

   Abstract : Supersonic airflow is usually described by a nonlinear hyperbolic system of equations. In this thesis we consider an aircraft represented by a union of thin plates orthogonal to the direction of Right, and describe the derivation of an approximate linear model for the airflow around it. The linear model is reduced to a system of integral equations. READ MORE

5. 23. Homogenization of reaction-diffusion problems with nonlinear drift in thin structures

   Author : Vishnu Raveendran; Adrian Muntean; Emilio N.M. Cirillo; Claudia Timofte; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Thin layer; homogenization; dimension reduction; reaction-diffusion-convection problem; two-scale convergence; effective transmission condition; fast drift; weak solvability of quasi-linear parabolic systems in unbounded domains.; Matematik; Mathematics;

   Abstract : We study the question of periodic homogenization of a variably scaled reaction-diffusion equation with non-linear drift of polynomial type. The non-linear drift was derived as hydrodynamic limit of a totally asymmetric simple exclusion process (TASEP) for a population of interacting particles crossing a domain with obstacle. READ MORE

6. 24. Analysis of adhesively bonded joints : an asymptotic approach

   Author : Peter Schmidt; Anders Klarbring; Anders Boström; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive Joints; Asymptotic Expansion; Engineering mechanics; Teknisk mekanik;

   Abstract : Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of using adhesive bonding, there is an increasing need for effective and accurate computational methods. READ MORE

7. 25. Nonlinear Beam Physics

   Author : Benjamin Folsom; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonlinear dynamics; Beam dynamics; Accelerator Physics; space charge; Accelerator magnets; simulations multi-particle dynamics;

   Abstract : A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator. READ MORE
