Based on suitable video recordings of interactive pedestrian motion and improved tracking software, we apply an evolutionary optimization algorithm to determine optimal parameter specifications for the social force model. The calibrated model is then used for large-scale pedestrian simulations...

Merchanting is goods trade that does not cross the border of the firm's country of residence. Merchanting grew strongly in the last decade in several small open economies, particularly in Finland, Ireland, Sweden, and Switzerland, and has become an important driver of these countries' current...

We propose a new family of Newton-type methods for the solution of constrained systems of equations. Under suitable conditions, that do not include differentiability or local uniqueness of solutions, local, quadratic convergence to a solution of the system of equations can be established. We...
