In-operation vibration monitoring for complex mechanical structures and rotating machines is of key importance in many industrial areas such as aeronautics (wings and other structures subject to strength), automobile (gearbox mounting with a sports car body), rail transportation, power engineering (rotating machines, core and pipes of nuclear power plants), and civil engineering (large buildings subject to hurricanes or earthquakes, bridges, dams, offshore structures). Tools for the detection and the diagnosis of small changes in vibratory characteristics are particularly useful to set up a preventive maintenance policy based on the actual evolution of the state of the monitored machine or structure, as opposed to systematic a priori planning. Ambient Vibration Monitoring is the backbone of such structural assessment monitoring and control. It provides the possibility to gain useful data under ambient conditions for the assessment of structures and components. Written by a widely respected authority in this area, Ambient Vibration Monitoring describes the current practice of ambient vibration methodologies illustrated by a number of practical examples. Designed to aid the practical engineer with their understanding of the topic, it is the culmination of many years of practical research and includes numerous ‘real world’ examples. It also provides information on applicable solutions. This book will enable not only practitioners (in civil, mechanical and aerospace engineering), but also researchers and students, to learn more about the theory and practical applications of this subject.

At the invitation of the Deutsche Forschungsgemeinschaft (DFG), a round-table discussion was held on 9 and 10 March 2000, dealing with future possibilities for biomonitoring in occupational and environmental medicine. Biomonitoring has reached a high standard in Germany over the past 30 years, not least due to the fact that the results of the Senate commission on materials hazardous to health at the workplace have been directly implemented as part of the jurisdiction relating to occupational safety. This book combines the expertise gathered from various areas within toxicology, occupational medicine, immunology and human genetics, right up to analysis and epidemiology. Throughout, the focus is on comprehensively determining the diagnostic validity of cytogenetic parameters as well as biochemical and biological effect markers for the prevention of illnesses resulting from harmful substances. Thus, the discussion allowed an initial exchange of ideas, pointing to future research, so as to maintain Germany's leading role in this important and rapidly expanding field. «…provides an excellent tutorial on the use of biological monitoring in occupational and environmental medicine…should be read by everyone involved with exposure analysis.» – Chemical Chemistry
