Dynamic optimization of track components to minimize rail corrugation

In this paper, the influence on corrugation of the most significant track parameters has been examined. After this parametric study, the optimization of the track parameters to minimize the undulatory wear growth has been achieved. Finally, the influence of the dispersion of the track and contact parameters on corrugation growth has been studied. A method has been developed to obtain an optimal solution of the track parameters which minimizes corrugation growth, thus ensuring that this solution remains optimum despite dispersion of track parameters and wheel-rail contact uncertainties. This work is based on the computer application RACING (RAil Corrugation INitiation and Growth) which has been developed by the authors to predict rail corrugation features.

A comprehensive method for the elastic calculation of the two-point wheel-rail contact

This work shows the method developed to solve the wheel-rail contact problem via a look-up table with a three-dimensional elastic model. This method enables introduction of the two contact point effect on vehicle movement using three-dimensional analysis of surfaces including the influence of the angle of attack. This work presents several dynamic simulations and studies the impact that the introduction of the two contact points on three dimensions has on wear indexes and derailment risk against traditional bidimensional analysis. Furthermore, it studies advantages and disadvantages of using a look-up table against an on-line resolution of the problem.

La aportación de W. von Humboldt a la gramática vasca

[EN] The aim of this paper is to introduce the main contributions of Humboldt to the study of the Basque grammar. His methodological innovations and the influence he had on european linguists are pointed out, the grammatical sources available to him are mentioned and his woks on Basque grammar are enumerated. Some of Humboldt's most interesting analysis are mentioned and are placed in the former and later tradition of the Basque grammar.

Astarloaren ekarpena euskal gramatikaren ikerketetan

Astarloaren Discursos filosóficos: iturrak eta axiomak

Astarloa's Discursos filosóficos is the most extensive and detailed apology of the Basque language as the first language of mankind. The text was finished in 1805 but the first edition was published in 1883. In this paper I attempt to sketch the main linguistic and philosophic ideas that could have an influence in Astarloa's thought. Then I deal with Astarloa's characterization of the first language, and the three principles he used to verify that Basque was that first language of human beings.

Berriz Aizkibelen Euskera eskuizkribuaz : Edizio eta iturriak

[EN] In this paper I offer a new edition of the Euskera manuscript, written by the bascologist J.F. Aizkibel in 1856. The preliminary study focuses on a survey of the sources extensively used by Aizkibel, which are mainly two: Schleicher's Die Sprachen Europas (1850 [1852]) and Champollion-Figeac's Égypte ancienne (1840). Moreover, the comparison with the sources reveals us that Aizkibel intended to adapt Schleicher’s and Champollion-Figeac's analyses to attest that Basque was originally a very ancient monosyllabic language, and that it was spoken by cultured people. Some other linguistic ideas of Aizkibel are also discussed.
