Measurements and modelling of residual stresses during quenching of thick heat treatable aluminium components in relation to their precipitation state

In the fabrication of heat treatable aluminium parts, solutionising and quenching are key steps in order to obtain the required mechanical characteristics. Fast quenching is necessary to avoid coarse precipitation as this one reduces the mechanical propert ...

Analysis of surface drag over Antarctic sea ice from High-Resolution measurements from Terrestrial Laser Scanning and Large Eddy Simulations

Michael Lehning, Marc Parlange, Katherine Colby Leonard, Charles Vivant Ignacio Meneveau, Ernesto Trujillo Gomez, Marco Giovanni Giometto

Sea ice/snow surface interactions with the atmosphere are major drivers of large-scale patterns of sea ice flows and deformations in Polar Regions. Climate and weather prediction models require parameterizations of the subgrid-scale surface drag caused by ...

Use of a multilayer snow model to assess grazing conditions for reindeer

Michael Lehning

High-density snow layers deteriorate grazing conditions for reindeer during winter. We compare two different methods for identifying past winters with difficult grazing conditions for reindeer in Kautokeino, northern Norway. A long-term climate analysis ba ...

Evaluation of subgrid-scale models in large-eddy simulation of flow past a two-dimensional block

Fernando Porté Agel, Wai Chi Cheng

Large-eddy simulations of flow past a two-dimensional (2D) block were performed to evaluate four sub-grid-scale (SGS) models: (i) the traditional Smagorinsky model, (ii) the Lagrangian dynamic model, (iii) the Lagrangian scale-dependent dynamic model, and ...

Flood management in a complex river basin with a real-time decision support system based on hydrological forecasts

Javier García Hernández

In alpine valleys with strong urban development, river training works for flood safety become more and more difficult to implement because of economic and environmental constraints. Thus flood management has a great importance especially in river basins eq ...

Improving the Turbulence Coupling between High Resolution Numerical Weather Prediction Models and Lagrangian Particle Dispersion Models

Balazs Szintai

For the modelling of the transport and diffusion of atmospheric pollutants during accidental releases, sophisticated emergency response systems are used. These modelling systems usually consist of three main parts. The atmospheric flow conditions can be si ...

Trajectory generation for aircraft subject to dynamic weather uncertainty

Maryam Kamgarpour

Determining safe aircraft trajectories that avoid hazardous weather regions and other aircraft while efficiently using the available airspace is an important problem. Although tactical weather forecast maps have been available, their use in automated aircr ...

POP-C++ and Alpine3D: Petition for a New HPC Approach

Michael Lehning, Mathias Thierry Pierre Bavay, Pierre Kuonen

In the developed world, an ever better and finer understanding of the processes leading to natural hazards is expected. This is in part achieved using the invaluable tool of numerical modeling, which offers the possibility of applying scenarios to a given ...

Structuring and integrating human knowledge in demand forecasting: a judgemental adjustment approach

Naoufel Cheikhrouhou

Demand forecasting consists of using data of the past demand to obtain an approximation of the future demand. Mathematical approaches can lead to reliable forecasts in deterministic context through extrapolating regular patterns in time-series. However, un ...

A new structured adjustment approach for demand forecasting

Naoufel Cheikhrouhou

Demand forecasting consists of using data of the past demand to obtain an approximation of the future demand. Mathematical approaches can lead to reliable forecasts in deterministic context, extrapolating regular patterns in series. However unpredictable e ...
