Turbulent separated flows around an airship-like geometry (a prolate spheroid 6:1) are investigated using three turbulence modelings based on statistical and Large Eddy Simulation (LES) approaches. The turbulence models used in the simulations are a standard high Reynolds k–ε model, a Smagorinsky LES model and a variational multiscale LES one. The flow of interest is characterized by a relative...

In industrial environments, numerical simulation has become an indispensable tool for the development and optimization of especially front-end processes. In order to remain useful for future technology nodes, process simulation has to follow and partly even anticipate paradigm shifts of state-of-the-art processes and new materials for future nanoelectronic devices. Within this article, the auth...

Financial institutions are increasingly using economic capital models to help determine the amount of capital they need to absorb unexpected losses. These models typically aggregate capital based on business-level analysis. However, important challenges surround this aggregation as well as other aspects of these models. Supervisors could use these capital calculations when they assess capital a...

Our goal as education researchers is to make a difference. We want to help students learn better, or perhaps we want them to learn just as well but at lower cost to our institutions. Decades of research tell us that it is difficult to make a significant difference with technology. This is especially true if we are trying to do the same things. The true value of new technology comes when it perm...

Proper education of a modeling and simulation professional meeting the extensive criteria imposed by the community poses significant challenges. In this paper, we explore the formation of a university-based education in modeling and simulation to meet the challenges. We examine the factors affecting the composition of a modeling and simulation course. Based on the anticipated consequences, we p...

Modeling interaction with robots raises new and different challenges for dialog modeling than traditional dialog modeling with less embodied machines. We present four case studies of implementing a typical humanrobot interaction scenario with different state-of-the-art dialog frameworks in order to identify challenges and pitfalls specific to HRI and potential solutions. The results are discuss...
