Viscous radiation driven disks in fast rotating massive stars
(Universidad de Valparaíso, 2022-08)
Previous studies of equatorial winds from high rotating massive stars, considered angular momentum conservation, have found a dependency between stellar rotation rate (Ω) and a new type of solution: the Ω-slow solution ...
Rotações tridimensionais em biomecânica via quatérnions: aplicações na análise dos movimentos esportivos
(Universidade Estadual Paulista (Unesp), 2009-02-06)
Algumas abordagens matemáticas são utilizadas para descrever o componente rotacional das articulações durante o movimento humano, como por exemplo, as matrizes de rotação do tipo 3x3, ângulos de Euler e Cardan, os eixos ...
Rotações no espaço tridimensional por meio de produtos quaterniônicos
(Universidade Estadual Paulista (Unesp), 2016-04-20)
The aim of this work is to describe the construction of the quaternion algebra and to interpret the multiplication operation via tridimensional rotations. For that we begin with basic algebraic concepts, and we list the ...
Non-isotropic distributions of stellar rotational velocities
(Universidad de Valparaíso, 2021-03)
Stellar rotation is defined from the angular motion of a star about its own rotational axis and study this phenomenon is useful to constrain models of stellar formation and evolution. The equatorial velocity v is defined ...
