Semi-implicit BDF time discretization of the Navier–Stokes equations with VMS-LES modeling in a High Performance Computing framework

In this paper, we propose a semi-implicit approach for the time discretization of the Navier–Stokes equations with Variational Multiscale-Large Eddy Simulation turbulence modeling (VMS-LES). For the spatial approximation of the problem, we use the Finite E ...

International portfolios: A comparison of solution methods

Serhiy Stepanchuk

We compare the performance of the perturbation-based (local) portfolio solution method of Devereux & Sutherland (2010a, 2011) with a global solution method. As a test suite we use model specifications that broadly capture features of international financia ...

What You Need to Know About SDN Flow Tables

Dejan Kostic, Peter Peresini, Maciej Leszek Kuzniar

SDN deployments rely on switches that come from various vendors and differ in terms of performance and available features. Understanding these differences and performance characteristics is essential for ensuring successful deployments. In this paper we me ...

Buoyant turbulence kinetic energy (TKE) production in katabatic flow despite stable thermal stratification

Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Eric Richard Pardyjak

As micrometeorological research shifts to increasingly non-idealized environments, the lens through which we view classical atmospheric boundary layer theory must also shift to accommodate unfamiliar behavior. We present observations of katabatic flow over ...

Morphodynamic differences induced by different confluence angles in widen confluences

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso

River widening is commonly used as a solution for the rehabilitation of rivers with the main purposes of allowing the river to adjust to its natural dynamics and to improve riparian and instream habitat for flora and fauna, by increasing the heterogeneity ...

Urban Experience: Remix of Attachments

Alexandre André Robert Rigal

I propose an essay for understanding how we experiment the fluidity, the density and diversity of the urban space. I purpose to reveal what I call the remix experience, that is to say the habit to of newness and otherness. This habit shows us the importanc ...

Isogeometric Analysis for the Elastic Wave Equation

Christoph Jäggli

In everyday life of an engineer, CAD (Computer Aided Design) and FE (Finite Element) programs play an important role. The two different structures, CAD and FE programs, use different mathematical functions. In CAD programs, so called NURBS find their appli ...

Determination of External Forces in Alpine Skiing Using a Differential Global Navigation Satellite System

Julien Chardonnens

In alpine ski racing the relationships between skier kinetics and kinematics and their effect on performance and injury-related aspects are not well understood. There is currently no validated system to determine all external forces simultaneously acting o ...
