After it emerged as a market commodity in the 18th century, coffee was easily adapted to cultivation in the highlands of Central America. Guatemala in particular has relied on coffee cultivation as a part of its economic identity: it has been a premier export crop for over 300 years. The importance of coffee to the country lies in the large labour investment in each stage of production. The book covers agricultural, social, and cultural aspects of coffee culture in Guatemala in old photographs, charts, tables and maps. Wagner's work shows how Guatemala has met the economic complexity to which this product is subject, and why coffee remains the solid foundation crop of the country today.
This book constitutes the refereed proceedings of the Second Mexican International Conference on Artificial Intelligence, MICAI 2002, held in Mérida, Yucatán, Mexico in April 2002. The 56 revised full papers presented were carefully reviewed and selected from more than 85 submissions from 17 countries. The papers are organized in topical sections on robotics and computer vision, heuristic search and optimization, speech recognition and natural language processing, logic, neural networks, machine learning, multi-agent systems, uncertainty management, and AI tools and applications.
First published in 1990. The contributors discuss the organizations for provision of science and technology advice to the highest levels of governments of some 35 countries, including major countries of the world and a selection of important smaller countries. Inclusion of some communist and developing countries adds piquancy. The papers comment on functioning of those organizations as well as describe their formal structure. Each author was asked to describe the science and technology advising organizations for the highest level of his or her country's government and comment on its effectiveness and how it influences policy formulation and action.
Non-destructive testing (NDT) is based on inspection methodologies that do not require the change or destruction of the component or system under evaluation. Numerous NDT techniques are increasingly used, thanks to the recent advances in sensing technologies, data acquisition, data storage and signal processing. Inspection information is widely employed in order to make effective maintenance decisions based on the defects identified, their location and severity. This book presents the main advances recently made on different NDT techniques, together with the principal approaches employed to process the signals obtained during inspection.
