(Complete work in Spanish) Remote sensing aerial spectral imaging was one of the first application areas where spectral imaging was used in order to identify and monitor the natural resources and covers on earth surface. Aerial spectral imaging is being developed with the aim of monitoring natural resources like coastal areas, forestry and extensive crops. The information contained in hyperspectral images allows the reconstruction of the energy curve radiated by the terrestrial surface throughout the electromagnetic spectrum. Hence, the characterization, identification and classification of...

Objeto del presente libro es la exposición de la teoría de los campos electromagnético y gravitatorio. De acuerdo con el plan general del Curso de Física teórica, no se tratan en este tomo las cuestiones de Electrodinámica de los medios continuos, limitándose a exponer la Electrodinámica microscópica, es decir, la Electrodinámica del vacío y de las cargas puntuales. Los dos últimos capítulos contienen la teoría de los campos gravitatorios, esto es, la teoría general de la relatividad. No se presupone en el lector un conocimiento previo del análisis tensorial, que se expone...
