Este objeto de aprendizaje comienza por exponer las distintas tipologías de aeronaves para el transporte de mercancías, mostrando ejemplos.
A continuación se profundiza en las ventajas e inconvenientes del transporte de ...
[EN] In rail transport, track gauge is one of the principal factors that condition the passage of trains. For technical and economic reasons, in some circumstances it is necessary to build and operate the so-called dual ...
Montalbán Domingo, María Laura; Fernández-Villa, J. A.; Masanet Sendra, Claudio; Real Herráiz, Julia Irene(SAGE PUBLICATIONS LTD, 2015)
The formula derived from Zimmermann s theory is commonly used in railway track design. However, this formula depends on variables such as the ballast coefficient, which are difficult to determine. In recent years, numerical ...
