Experimental study on the influence of abrupt slope changes on flow characteristics over stepped spillways

Mohammad Javad Ostad Mirza

Application of stepped spillways increases the energy dissipation rate along the spillway and may reduce the dimensions of the terminal energy dissipation structure. This pronounced energy dissipation makes stepped chutes attractive under various condition ...

Photon energy dependence of the light pressure exerted onto a thin silicon slab

Giovanni Boero, Franz-Karl Reinhart

We review the theory of ponderomotive forces of classical nonionizing electromagnetic (EM) radiation exerted on dispersive matter. Minkowski's EM energy and momentum density lack any dispersion term in contrast to Nelson's theory, where they are included n ...

The effects of mutual location-awareness on group coordination

Pierre Dillenbourg, Nicolas Nova

The importance of space and place in collaborative practices has been strengthened with the ubiquitous computing paradigm, which aims at the integration of computation in physical objects and places. New location-based applications allow users to know wher ...

Techniques for generating centimetric drops in microgravity and application to cavitation studies

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset

This paper describes the techniques and physical parameters used to produce stable centimetric water drops in microgravity, and to study single cavitation bubbles inside such drops (Parabolic Flight Campaigns, European Space Agency ESA). While the main sci ...
