A family of smooth controllers for swinging up a pendulum
(2008)
The paper presents a new family of controllers for swinging up a pendulum. The swinging up of the pendulum is derived from physical arguments based on two ideas: shaping the Hamiltonian for a system without damping; and ...

Dualité et comparaison sur les complexes de de Rham logarithmiques par rapport aux diviseurs libres
(Association des Annales de l'Institut Fourier, 2005)
Let X be a complex analytic manifold and D \subset X a free divisor. Integrable logarithmic connections along D can be seen as locally free {\cal O}_X-modules endowed with a (left) module structure over the ring of logarithmic ...

Meson-exchange currents in (e,e'p) recoil polarization observables
(American Physical Society, 2003-09-01)
A study of the effects of meson-exchange currents and isobar configurations in A(e,e'p)B reactions is presented. We use a distorted wave impulse approximation model where final-state interactions ...

Inferring efficient weights from pairwise comparison matrices
(Springer, 2006-10)
Several multi-criteria-decision-making methodologies assume the existence of weights associated with the different criteria, reflecting their relative importance.One of the most popular ways to infer such weights is the ...

Induced nucleon polarization and meson-exchange currents in (e,e'p) reactions
(American Physical Society, 2004-06-01)
Nucleon recoil polarization observables in (e,e'p) reactions are investigated using a semirelativistic distorted-wave model which includes one- and two-body currents with relativistic corrections. Results for ...

Existence and regularity of the pressure for the stochastic Navier-Stokes equations
(Springer, 2003-10)
We prove, on one hand, that for a convenient body force with values in the distribution space (H−1(D))d, where D is the geometric domain of the fluid, there exist a velocity u and a pressure p solution of the stochastic ...

The nth root of a braid is unique up to conjugacy
(Mathematical Sciences Publishers, 2003-11-01)
We prove a conjecture due to Makanin: if α and β are elements of the Artin braid group Bn such that α k = β k for some nonzero integer k, then α and β are conjugate. The proof involves the Nielsen-Thurston classification ...
