Berry-phase theory of polar discontinuities at oxide-oxide interfaces

Massimiliano Stengel

In the framework of the modern theory of polarization, we rigorously establish the microscopic nature of the electric displacement field D. In particular, we show that the longitudinal component of D is preserved at a coherent and insulating interface. To ...

On the naturality of the exterior differential

Marc Troyanov

We give sufficient conditions for the naturallity of the exterior differential under Sobolev mappings. In other words we study the validity of the equation

d\, f^* \alpha = f^*\; d\alpha

for a smooth form

\alpha

and a Sobolev map

Pelvic Motion Implementation on the WalkTrainer

Mohamed Bouri, Reymond Clavel, Patrick Métrailler, Jacques Fournier

Pelvic motion is of great importance when walking, and have thus to be taken into account while developing rehabilitation robotics. This paper describes the implementation of a pelvic motion amplitude prediction model on a pelvic orthosis and tests on vali ...
