Demuestra que un campo de Morse - Smale, definida en una variedad compacta de dimensión dos, es estructuralmente estable, esto es, que el comportamiento topológico de sus órbitas no se altera mediante pequeñas perturbaciones ...

This study discusses and analyzes the concept of the stability parameter in order to set the calculation expressions that allow the design of erodible channels. With the conceptual exposure of these processes, we have ...

O intuito deste trabalho é de integrar os aspectos aplicado e teórico da Homologia Persistente, uma ferramenta popular da Topological Data Analysis (TDA). Para isso, são apresentados e demonstrados os resultados fundamentais ...

A critical parameter in machining processes is the final surface quality of the machined part, directly related to self-excited vibrations that arise in these processes due to the interaction between the cutting tool and ...

Chatter are self-excited vibrations that may occur during machining operations. Despite being known for more than a century, chatter is still a major limiting factor on machining operations, decreasing productivity, tool ...

En 1845, Pierre F. Verhuls introdujo un modelo para simular el crecimiento de una población en una área cerrada. Este modelo, llamado logístico, establece que la población x(t) cambia con el tiempo t según la relación donde ...
