Darboux invariants for planar polynomial differential systems having an invariant conic
(Springer, 2014-12-01)
We characterize all the planar polynomial differential systems with a unique invariant algebraic curve given by a real conic and having a Darboux invariant.
Origin of conical dispersion relations
(Sociedad Mexicana de Fisica, 2014)
A mechanism that produces conical dispersion relations is presented. A Kronig Penney one dimensional array with two different strengths delta function potentials gives rise to both the gap closure and the dispersion relation ...

Environment mapping for mobile robots navigation using hierarchical neural network and omnivision
(2008-11-24)
Autonomous robots must be able to learn and maintain models of their environments. In this context, the present work considers techniques for the classification and extraction of features from images in joined with artificial ...

Classification and characterization of places for mapping of environment using hierarchical neural network and omnivision
(Slovak Univ Tech Bratislava, 2008-01-01)
Mobile robots need autonomy to fulfill their tasks. Such autonomy is related whith their capacity to explorer and to recognize their navigation environments. In this context, the present work considers techniques for the ...
