Combustion Characteristics of Premixed Hydrogen/Air in an Undulate Microchannel
(2022-01-01)
This work reports a numerical investigation of microcombustion in an undulate microchan-nel, using premixed hydrogen and air to understand the effect of the burner design on the flame in order to obtain stability of the ...

Coarse geometry on proper geodesic spaces
(Universidad Michoacana de San Nicolás de Hidalgo, 2022-06)
In this work the large-scale geometry of proper geodesic spaces is discussed in the framework of Coarse Geometry, which is briefly introduced. Also, the Higson corona for general coarse spaces, the space of ends for proper ...
Origin of time before inflation from a topological phase transition
(Elsevier Science, 2017-09)
We study the origin of the universe (or pre-inflation) by suggesting that the primordial space–time in the universe suffered a global topological phase transition, from a 4D Euclidean manifold to an asymptotic 4D hyperbolic ...
Bilhares com obstáculos
(Universidade Federal de Minas GeraisUFMG, 2015-12-04)
We consider planar focusing billiards on annular tables constructed by adding a circular obstacle of center p and radius r in the interior of a region bounded by a convex curve . Parameterized families of billiards are ...
Elementos reversíveis e fortemente reversíveis em U(n), SU(n), U(n,1), SU(n,1) e PU(n,1)
(Universidade Federal de Minas GeraisUFMG, 2015-11-26)
This dissertation presents a complete classification of the reversible and strongly reversible elements in the holomorphic isometries group of the complex hyperbolic space, denoted by PU(n; 1), and in the groups U(n), ...
