Galilei Covariance and (4,1)-de Sitter Space

A vector space G is introduced such that the Galilei transformations are considered linear mappings in this manifold. The covariant structure of the Galilei Group (Y. Takahashi, Fortschr. Phys. 36 (1988) 63, 36 (1988) 83) is derived and the tensor analysis is developed. It is shown that the Euclidean space is embedded the (4,1) de Sitter space through in G. This is an interesting and useful asp...

Análisis del algoritmo de optimización por enjambre de partículas por medio de una aplicación gráfica 3D

Particle swarm optimization method has become popular in recent years, because of its efficiency and low computational cost. In this document, a brief analysis of the standard algorithm is performed by a 3D application. The source code of the application is free software and you can download at GitHub.

Galileo's eye: a new vision of the senses in the work of Galileo Galilei.

Reflections on the senses, and particularly on vision, permeate the writings of Galileo Galilei, one of the main protagonists of the scientific revolution. This aspect of his work has received scant attention by historians, in spite of its importance for his achievements in astronomy, and also for the significance in the innovative scientific methodology he fostered. Galileo's vision pursued a ...

Modelado de la agregación de portlets por medio de statecharts

Resumen. El portal proporciona integración a través del interfaz gráfico (front-end), mientras que otras tecnologías soportan integración a través de los datos o de los procesos (back-end). La sindicación de portlets (aplicaciones front-end) sigue la estela de la sindicación de contenidos. El portal sería un contenedor de portlets, para proporcionar aplicaciones de mayor calado. La agregación d...
