This study shows how, in the initial training of mathematics teachers, it is possible to promote processes of abstraction and mathematisation through modelling a real situation with the support of auxiliary material to ...

Virtual Worlds Generator is a grammatical model that is proposed to define virtual worlds. It integrates the diversity of sensors and interaction devices, multimodality and a virtual simulation system. Its grammar allows ...

The research paper describes the development of a user friendly 3D virtual world. For the research, we modeled building number 3 of the Technological University of Panama, Victor Levi Sasso Campus. For the virtual world ...

We consider a brane-world cosmological model coupled to a bulk scalar field. Since the brane tension turns out to be proportional to Newton’s coupling G, in such a model a time variation of G naturally occurs. By resorting ...

The course provides the students the knowledge of the economic variables that have the international financial markets which affect the private and public corporations, to increase the capital and to create portfolios of ...

Abstract: The international economic system is threatened, not only by the economic effects of the financial crisis, but also by the different interpretations on how the system should be reorganized. The different views ...
