Cavitation tests using models are essential to determine the full-scale machine cavitation behaviour. As erosion prediction is still very empirical, in practice a "safe" machine shows no visible cavitation on a model at sigma plant. However, this way of de ...

This paper presents a novel modular methodology to design ultra-high precision parallel robots. It chiefly aims at significantly decreasing both the complexity of their synthesis and their development time. This approach can be compared to a robotic Lego®, ...
A monocrystalline silicon lever with an integrated silicon tip for a Force/Friction Microscope was realized. Theoretical studies have been carried out to find the shape and dimensioning according to the mechanical system requirements. Moreover, sharp tips ...

Current theories in the qualitative simulation field tend to draw lines between the dynamic and kinematic behaviors of physical systems. However, cognitive scientists (Metz) believe that humans, including children, seem to have a unified knowledge represen ...
Presents a human walking model built from experimental data based on a wide range of normalized velocities. The model is structured on two levels. On the first level, global spatial and temporal characteristics are generated. On the second level, a set of ...
Motion control of robotic or manipulator joints, tool machines axes or more genrally of drive systems require accurate position, velocity and possibly acceleration control. Today, these controls are almost always realized using digital controllers. Therefo ...
The cavitation which causes severe erosion of hydraulic machine runners is produced by the development of fixed cavities attached at the leading edge of the blades. It is clearly shown, from a comparison between the observations of cavity patterns during m ...

This paper presents a human walking model built from experimental data based on a wide range of normalized velocities. The model is structured in two levels. At a first level, global spatial and temporal characteristics (normalized length and step duration ...
Hydropower plants play an important regulatory role in the large scale integration of volatile renewable energy sources into the existing power grid. This duty however requires a continuous extension of their operating range, provoking the emergence of com ...
