The characterization of a heterogeneous aquifer involves a wide spectrum of high resolution direct measurements of the characteristic parameters, defined in itinere according to the various approaches used. This information is usually obtained from the pumping tests and the relative measurements of the drawdown induced. Unfortunately, these methods are intrusive and the hydrological system is p...

During the last century, many general purpose programming languages have been developed, all having rigid syntax and often a von-Neuman view of the world. With the rise of model-based development this changes: Featureoriented programming, domain specific languages, and platform-based design use rich and custom syntaxes to capture domain specific abstractions, refinement mappings, and design spa...

We investigate the spreading of information in a one-dimensional BoseHubbard system after a sudden parameter change. In particular, we study the timeevolution of correlations and entanglement following a quench. The investigated quantities show a light-cone like evolution, i.e. the spreading with a finite velocity. We discuss the relation of this veloctiy to other characteristic velocities of t...

The new learning dynamic of Brown, von Neuman and Nash (1950) is introduced to macroeconomic dynamics via the cobweb model with rational and naive forecasting strategies. This dynamic has appealing properties such as positive correlation and inventiveness. There is persistent heterogeneity in the forecasts and chaotic behavior with bifurcations between periodic orbits and strange attractors for...
