Different parameters from the analysis of the glass transition, such as the glass transition temperature (Tg), were used in order to monitor this isothermal aging at 65 °C during a total time of 3000 h, finding an increasing and broadening Tg. In addition, the accelerated aging behaviour of these materials was also studied by a classical method, based on the change of mechanical properties such as those of Young's modulus or strain at break. The correlation between both methodologies was examined, demonstrating that an analytical technique such as DSC allows the evaluation of the actual state of composite solid propellants with a small sample and a straightforward measurement.

The model has been profusely tested for technology watch, economic intelligence, and competitive intelligence related purposes within a general framework of technology deployment in a clean and renewable focused nnovation department. As a practical example, is proposed, step by step, how to launch a fully operative specialized cell for analyzing how to deal with electric mobility, battery technologies and electric car issues so that challenges, opportunities, and threats can be tracked and nticipated so that a business strategy might be established.

Todos o casi todos se han estudiado en otras asignaturas de cursos anteriores a aquél en el que se imparte ésta. En ningún caso es un exhaustivo recordatorio de las matemáticas elementales que debe conocer un ingeniero industrial. También se introduce una cierta notación que, de forma uniforme, trataremos de usar en todas las lecciones y presentaciones de las clases.
