Modeling snow drift in the turbulent boundary layer

Gian-Duri Lieberherr

The modeling of snow redistribution in turbulent conditions plays an important role for the prediction of snow accumulation and avalanche risk. For this aim two Lagrangian models, one for the suspension and one for the saltation of snow were coupled. The s ...

Immobilized polymer fraction in hyperbranched polymer/silica nanocomposite suspensions

Yves Leterrier, Sara Dalle Vacche, Valérie Geiser, Riccardo Ruggerone

The glass transition behavior of hyperbranched polymer (HBP) molecules with suspensions of silica and glass particles up to the concentrated regime (25 vol %) was analyzed by modulated differential scanning calorimetry (MDSC). The reversing and nonreversin ...

American Chemical Society2010

Functionalization of colloidal particles based on the use of polyelectrolytes and heterocoagulation was combined with electrophoretic deposition (EPD), with the aim of depositing titania-polystyrene (TiO2-PS) composite particles on Ti6A14V substrates. The ...

Cuba, Best Practices: quel potentiel d'élargissement

The present article evaluates the knowledge that can be attributed to the application of « Best Practices » in the field of urban habitat. It especially aims at identifying the conditions of innovation in such a setting, as well as defining the necessary c ...

2007

Information about the locomotion performance of known rovers is sparse. A comprehensive evaluation of wheeled passive systems is presented in this work. It is based on a static 2D approach that includes optimization of the wheel torques in order to minimiz ...

Yodel: A Yield Stress Model for Suspensions

Paul Bowen

A model for the yield stress of particulate suspensions is presented that incorporates microstructural parameters taking into account volume fraction of solids, particle size, particle size distribution, maximum packing, percolation threshold, and interpar ...

Correlation-Based Tuning of a Restricted-Complexity Controller for an Active Suspension System

Dominique Bonvin, Alireza Karimi, Ljubisa Miskovic

A correlation-based controller tuning method is proposed for the \Design and optimization of restricted-complexity controllers" benchmark problem. The approach originally proposed for model following is applied to solve the disturbance rejection problem. T ...

Control of an Active Suspension System as a Benchmark for Design and Optimization of Restricted Complexity Controllers

Alireza Karimi, Ljubisa Miskovic

A benchmark problem for restricted complexity controller design is introduced. The objective is to design the lowest-order controller which meets the control specifications for an active suspension system. The input-output data of the plant are provided on ...

Correlation-Based Tuning of a Restricted-Complexity Controller for an Active Suspension System

Dominique Bonvin, Alireza Karimi, Ljubisa Miskovic

A correlation-based controller tuning method is proposed for the ``Design and optimization of restricted-complexity controllers'' benchmark problem. The approach originally proposed for model following is extended to solve the disturbance rejection problem ...

Squeeze flow of concentrated long fibre suspensions: experiments and model

Experimental squeeze flow results show that the behaviour of concentrated short fibre suspensions and concentrated long fibre suspensions impregnated with polymer melts are qualitatively different. Short fibre suspensions have a low yield stress, have an o ...
