Civil infrastructure systems are extraordinarily important for society. Our economy, security, health, and comfort depend directly or indirectly on the adequate transportation, habitat, and communication systems. Nowadays, in addition to the impact of strong natural and human made events, infrastructure's deterioration caused by natural use and aging is a concern of the engineering community around the world. As an example, the American Society of Civil Engineers (ASCE) have given an average grade of D to the infrastructure of the United States of America for more than 10 years with only a...

This book provides an extensive coverage of the design of reinforced concrete structures in accordance with the current Indian code of practice (IS 456: 2000). As some of the Indian code provisions are outdated, the American code provisions are provided, wherever necessary. In addition, an attempt is made to integrate the provisions of IS 456 with earthquake code (IS 13920), as more than 60% of India falls under moderate or severe earthquake zones. The text is based on the limit state approach to design and covers areas such as the properties of concrete, design of various structural elements ...

La modelación de la demanda es un elemento fundamental en la evaluación de proyectos de transporte, cuyas inversiones son muy altas y crecientes en el tiempo. En este texto se discute el rol de la teoría y la selección, especificación, adaptación y aplicación de modelos, de forma accesible, tanto a estudiantes como a profesionales. Se incluyen, además, técnicas para seleccionar el nivel de análisis y precisión más adecuados en cada caso.

There is an increasing challenge for chemical industry and research institutions to find cost-efficient and environmentally sound methods of converting natural resources into fuels chemicals and energy. Catalysts are essential to these processes and the Catalysis Specialist Periodical Report series serves to highlight major developments in this area. This series provides systematic and detailed reviews of topics of interest to scientists and engineers in the catalysis field. The coverage includes all major areas of heterogeneous and homogeneous catalysis and also specific applications of...
