Sommario/riassunto

El llamado Estudio de impacto ambiental constituye, sin duda, la piedra angular del procedimiento de Evaluación de Impacto Ambiental (EIA). En cuanto documento técnico, su realización suele corresponder a profesionales de formación científica, frecuentemente universitaria. Con todo, los estudios de EIA que vienen realizándose no siempre presentan la calidad necesaria como para ser instrumentos efectivos de una adecuada política ambiental. Los problemas, muchas veces, no provienen tanto de posibles errores técnicos, como de la escasa asimilación previa del enfoque, objetivos y requerimientos específicos de la EIA. En el presente libro se intenta, con la ayuda de numerosos ejemplos y ejercicios prácticos, proporcionar a las personas con formación científico-técnica las bases conceptuales y metodológicas que les permitan aplicar sus conocimientos para conseguir estudios de impacto ambiental más eficaces.

Sommario/riassunto

This book focuses on the constructive and practical aspects of spectral methods. It rigorously examines the most important qualities as well as drawbacks of spectral methods in the context of numerical methods devoted to solve non-standard eigenvalue problems. In addition, the



book also considers some nonlinear singularly perturbed boundary value problems along with eigenproblems obtained by their linearization around constant solutions. The book is mathematical, poising problems in their proper function spaces, but its emphasis is on algorithms and practical difficulties. The range of applications is quite large. High order eigenvalue problems are frequently beset with numerical ill conditioning problems. The book describes a wide variety of successful modifications to standard algorithms that greatly mitigate these problems. In addition, the book makes heavy use of the concept of pseudospectrum, which is highly relevant to understanding when disaster is imminent in solving eigenvalue problems. It also envisions two classes of applications, the stability of some elastic structures and the hydrodynamic stability of some parallel shear flows. This book is an ideal reference text for professionals (researchers) in applied mathematics, computational physics and engineering. It will be very useful to numerically sophisticated engineers, physicists and chemists. The book can also be used as a textbook in review courses such as numerical analysis, computational methods in various engineering branches or physics and computational methods in analysis.
