Affine skeletons and monge-ampere equations
(Siam Publications, 2009)
An important question about a. ne skeletons is the existence of differential equations that are related to the 'affine distance' and the 'area distance' (hence to a. ne skeletons) in the same way the Eikonal equation is ...

Weak solutions for a class of quadratic operator-differential equations
(UniandesMaestría en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2016)
"This monograph presents results of existence and uniqueness of generalized solutions for two classes of quadratic operator-differential equations with constant coefficients: (1) Au(t) + Bu'(t) - Du"(t) = 0 and (2) Au(t) ...
Spin stabilized satellite's attitude analytical prediction
(2012-10-01)
An analytical approach for spin stabilized attitude propagation is presented, considering the coupled effect of the aerodynamic torque and the gravity gradient torque. A spherical coordination system fixed in the satellite ...

Does water availability regulate biomass partitioning between trunk and branches?
(Wiley Blackwell Publishing, Inc, 2017-11)
The extent to which a vertical trunk is differentiated from its branches is a key trait for the architecture of trees and may affect interspecific relationships. In this study, we analysed the effect of soil water availability ...
