Raúl Mena: 1953–2014

Foreword Raúl

have edited this new book to reflect the present and future challenges in wireless technologies for vehicular ad hoc networks. New technologies are being developed for vehicular ad hoc networks, and these networks provide an efficient method for today's complex vehicle communications. Emerging vehicular ad hoc networks in the forms of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I)...

Divide and Conquer Author : Teresa Vaz Martins Supervisor : Raúl Toral

This thesis is about the effects of disorder in the response properties of nonlinear systems subjected to weak forcing. This is a very broad topic that began in the early 80s with the discovery of stochastic resonance, a phenomenon by which noise cooperates with a weak forcing to raise it above the threshold for detection. This effect has been observed and described in a plethora of physical an...

A Wavelets Analysis of MENA stock markets

In this paper we apply the wavelets methodology to the analysis of the comovements of for some MENA countries from June 1997 until March 2005. We decompose weekly stock market returns into di¤erent time scale components using the non-decimated discrete wavelet transform and then analyze the relationships among these variables at the di¤erent time scales. Keywords : Stock market returns, Wavelet...
