2. 1. Numerical ice sheet modeling : Forward and inverse problems

   Author : Gong Cheng; Lina von Sydow; Per Lötstedt; Nina Kirchner; Irina Tezaur; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ice sheet modeling; finite element method; grounding line migration; inverse problems; adjoint method; Scientific Computing; Beräkningsvetenskap;

   Abstract : Ice sheets have strong influence on the climate system. Numerical simulation provides a mathematical tool to study the ice dynamics in the past and to predict their contribution to climate change in the future. Large scale ice sheets behave as incompressible non-Newtonian fluid. READ MORE

4. 2. Estimating Effective Interactions from Particle Trajectories

   Author : Kolbjörn Tunström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mori-Zwanzig projection; Force matching; United atoms; Multi-scale molecular dynamics; Coarse-graining; Molecular dynamics thermostat; Inverse Monte Carlo; Dissipative particle dynamics; Swarming;

   Abstract : The theoretical and practical understanding of molecular systems is strongly dependent on computer simulations. All-atom molecular dynamics techniques are capable of sim- ulating systems on the scale of millions of particles up to about 100 ns. READ MORE

   Abstract : Double poling (DP) is a sub-technique in cross-country skiing that has increased in interest over the last decades, e.g. athletes in cross-country skiing have increased their utilisation of double poling during competitions. READ MORE

6. 4. Deriving coarse grained descriptions of particle based simulations

   Author : Johan Nyström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coarse graining; Mori-Zwanzig projection; Dissipative particle dynamics;

   Abstract : 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. Fully detailed molecular dynamics simulations can be extremely successful in many areas, but when applied to mesoscopic systems with a large number of molecules, the time and length scales on which important phenomena take place are often far beyond what is feasible to simulate with modern computers.

7. 5. Multiscale simulations of soft matter: systematic structure-based coarse-graining approach

   Author : Alexander Mirzoev; Alexander Lyubartsev; Nico van der Vegt; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multiscale modeling; Monte Carlo; Molecular dynamics; ion solution; lipid bilayer; coarse-graining; fysikalisk kemi; Physical Chemistry;

   Abstract : The soft matter field considers a wide class of objects such as liquids, polymers, gels, colloids, liquid crystals and biological macromolecules, which have complex internal structure and conformational flexibility leading to phenomena and properties having multiple spacial and time scales. Existing computer simulation methods are able to cover these scales, but with different resolutions, and ability to link them together performing a multiscale simulation is highly desirable. READ MORE
