Current Control Strategy for Dynamic Winding Reconfiguration of Slotless Brushless DC Motors

Yves Perriard, Douglas Martins Araujo, Florian Louis Copt

Depending on the winding configuration, the intrinsic characteristic of a motor differs. By reconfiguring the winding, it becomes possible to increase the torque–speed limitation of a motor. Current proposed methodologies for dynamically reconfiguring the ...

Inverse Rendering of Lambertian Surfaces Using Subspace Methods

Quy Ha Nguyen, Minh Do

We propose a vector space approach for inverse rendering of a Lambertian convex object with distant light sources. In this problem, the texture of the object and arbitrary lightings are both to be recovered from multiple images of the object and its 3D mod ...

Automatically calibrating the viewing direction of optic-flow sensors

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod

Because of their low weight, cost and energy consumption, optic-flow sensors attract growing interest in robotics for tasks such as self-motion estimation or depth measurement. Most applications require a large number of these sensors, which involves a fai ...

A Probabilistic Approach of Sum Rules for Heat Polynomials

Olivier Lévêque

In this paper, we show that the sum rules for generalized Hermite polynomials derived by Daboul and Mizrahi (2005 J. Phys. A: Math. Gen. 38 427-48) and by Graczyk and Nowak (2004 C. R. Acad. Sci., Ser. 1 338 849) can be interpreted and easily recovered usi ...

Stationary and time-dependent correlations in polariton condensates

Davide Sarchi

The statistics of the condensed polaritons is described in terms of the Wigner function. In the framework of the truncated Wigner method, the Wigner function obeys a Fokker-Planck equation, which is solved analytically. The second-order correlations in the ...
