This book reviews the sources of the air pollutants responsible for building damage and the mechanisms involved. Studies investigating the relationships between pollution concentration (dose) and the resulting damage (response) are described and the latest research findings for dose-response functions are presented. Trends in pollutant emissions, ambient concentrations and building damage over time are described and future predictions are presented. Methodologies for assessing the extent of the potential problem in a region - the stock at risk - are presented. Procedures for estimating the economic implications are described and the consequences are discussed in detail, because economic factors are important for reaching policy and management decisions at local, national and international scales. Damage to cultural heritage buildings is an important additional effect which needs to be considered as the standards are revised and the factors which will need to be brought into the assessment are presented.

This monograph was motivated by a very successful workshop held before the 3rd IEEE Conference on Decision and Control held at the Buena Vista Hotel, lake Buena Vista, Florida, USA. The workshop was held to provide an overview of polynomial system methods in LQG (or H ) and Hoo optimal control and 2 estimation. The speakers at the workshop were chosen to reflect the important contributions polynomial techniques have made to systems theory and also to show the potential benefits which should arise in real applications. An introduction to H2 control theory for continuous-time systems is included in chapter 1. Three different approaches are considered covering state-space model descriptions, Wiener-Hopf transfer function methods and finally polyno mial equation based transfer function solutions. The differences and similarities between the techniques are explored and the different assumptions employed in the solutions are discussed. The standard control system description is intro duced in this chapter and the use of Hardy spaces for optimization. Both control and estimation problems are considered in the context of the standard system description. The tutorial chapter concludes with a number of fully worked ex amples."
