flood routing has many applications in engineering projects and helps designers in understanding the flood flow characteristics in river flows. floods are taken unsteady flows that vary by time and location. equations governing unsteady flows in waterways are continuity and momentum equations which in case of one-dimensional flow the saint-venant hypothesis is considered. dynamic wave model as ...

In these lectures I describe some theoretical tools and numerical techniques to investigate glassy systems. The discussion is centered on spin glasses where there has been a large amount of theoretical as well as numerical work during the recent years. After discussing the utility of introducing real replicas in numerical simulations, I analyze topics such as equilibration methods and the analy...

SUMMARY Convection-dominated problems are typiied by the presence of strongly directional features such as shock waves or boundary layers. Resolution of numerical solutions using an isotropic mesh can lead to unnecessary reenement in directions parallel to such features. This is particularly important in three dimensions where the grid size increases rapidly during conventional isotropic reenem...

The Aurora Financial Management System developed at the University of Vienna is a decision support tool for portfolio and asset liability management. An investor chooses a portfolio of various assets or asset classes, in such a way that some objective 9], including a risk measure, is maximized, subject to uncertainty of future markets' development and additional constraints (e.g. budget restric...

The problem of finding periodic orbits of dynamical systems numerically is considered. It is shown that if a convergent, strongly stable, multi-step method is employed then under some suitable conditions, there exist invariant curves. The result also shows that the rates of convergence toward the invariant curves are roughly the same for different methods and different step sizes. Introduction....
