La inocencia robada: juventud, multinacionales y política cultural = Stealing innocence: Corporate culture's war on children

Este libro es una recopilación de diversos ensayos de su autor y, aunque en la contraportada se sugiere que hay un hilo conductor, una simple ojeada al índice ofrece una estructura bien extraña, carente de un capítulo final con reflexiones que globalicen, sinteticen o resuman lo expuesto, que lleven al lector a algún tipo de conclusión

Unusual voltage sag event detection in power systems

Three multivariate statistical tools (principal component analysis, factor analysis, analysis discriminant) have been tested to characterize and model the sags registered in distribution substations. Those models use several features to represent the magnitude, duration and unbalanced grade of sags. They have been obtained from voltage and current waveforms. The techniques are tested and compared using 69 registers of sags. The advantages and drawbacks of each technique are listed
