Money Makers as Peace Makers?
(2010)Swisspeace Working PapersSince the end of cold war, mediation processes have become more and more complex. Today, peace mediation includes a variety of actors, ranging from states, international organizations, NGOs to the private sector. Despite a growing number of practical examples for business engagement in conflict transformation, there are only a few insights into the contributions of business actors to mediation processes. Thus, the aim of this working paper ...Report -

Entropy stable schemes for initial-boundary-value conservation laws
(2010)SAM Research ReportWe consider initial boundary value problems for systems of conservation laws and design entropy stable finite difference schemes to approximate them. The schemes are shown to be entropy stable for a large class of systems that are equipped with a symmetric splitting, derived from the entropy formulation. Numerical examples for the Euler equations of gas dynamics are presented to illustrate the robust performance of the proposed method.Report -

Regularity and generalized polynomial chaos approximation of parametric and random 2nd order hyperbolic partial differential equations
(2010)SAM Research ReportInitial boundary value problems of linear second order hyperbolic partial differential equations whose coefficients depend on countably many random parameters are reduced to a parametric family of deterministic initial boundary value problems on an infinite dimensional parameter space. This parametric family is approximated by Galerkin projection onto finitely supported polynomial systems in the parameter space. We establish uniform ...Report -
