COMPUTATIONAL METHODS FOR RANDOM DIFFERENTIAL EQUATIONS: THEORY AND APPLICATIONS

Navarro Quiles, Ana (2018-03-01)

Desde las contribuciones de Isaac Newton, Gottfried Wilhelm Leibniz, Jacob y Johann Bernoulli en el siglo XVII hasta ahora, las ecuaciones en diferencias y las diferenciales han demostrado su capacidad para modelar ...
Contribuciones de la modelización al desarrollo de las competencias básicas

Sol, Manel (Universitat Politècnica de València, 2013-06-02)

[EN] For many years modelling activities have not been a common practice in the classroom despite having a wide recognition of their educational interest. Burkhardt i Pollack (2006) justify it by a lack of supporting ...
