The craft of designing mathematical models of dynamic objects offers a large number of methods to solve subproblems in the design, typically parameter estimation, order determination, validation, model reduc tion, analysis of identifiability, sensi tivi ty and accuracy. There is also a substantial amount of process identification software available. A typi cal 'identification package' consists of program modules that implement selections of solution methods, coordinated by supervising programs, communication, and presentation handling file administration, operator of results. It is to be run 'interactively', typically on a designer's 'work station' . However, it is generally not obvious how to do that. Using interactive identification packages necessarily leaves to the user to decide on quite a number of specifications, including which model structure to use, which subproblems to be solved in each particular case, and in what or der. The designer is faced with the task of setting up cases on the work station, based on apriori knowledge about the actual physical object, the experiment conditions, and the purpose of the identification. In doing so, he/she will have to cope with two basic difficulties: 1) The com puter will be unable to solve most of the tentative identification cases, so the latter will first have to be form11lated in a way the computer can handle, and, worse, 2) even in cases where the computer can actually produce a model, the latter will not necessarily be valid for the intended purpose.

Approximately 80% of the U.S. population now lives in urban metropolitan areas, and this number is expected to grow significantly in the coming years. At the same time, the built infrastructure sustaining these populations has become increasingly vulnerable to climate change. Stresses to existing systems, such as buildings, energy, transportation, water, and sanitation are growing. If the status quo continues, these systems will be unable to support a high quality of life for urban residents over the next decades, a vulnerability exacerbated by climate change impacts. Understanding this dilemma and identifying a path forward is particularly important as cities are becoming leading agents of climate action. Prepared as a follow-up to the Fourth National Climate Assessment (NCA), Climate Change and U.S. Cities documents the current understanding of existing and future climate risk for U.S. cities, urban systems, and the residents that depend on them. Beginning with an examination of the existing science since 2012, chapters develop connections between existing and emerging climate risk, adaptation planning, and the role of networks and organizations in facilitating climate action in cities. From studies revealing disaster vulnerability among low-income populations to the development of key indicators for tracking climate change, this is an essential, foundational analysis. Importantly, the assessment puts a critical emphasis on the cross-cutting factors of economics, equity, and governance. Urban stakeholders and decision makers will come away with a full picture of existing climate risks and a set of conclusions and recommendations for action. Many cities in the United States still have not yet planned for climate change and the costs of inaction are great. With bold analysis, Climate Change and U.S. Cities reveals the need for action and the tools that cities must harness to effect decisive, meaningful change.

The United States social security system is the nation's largest social insurance program. As such, it has a far-reaching impact throughout the economy, influencing not only old-age economic security but also many behaviors, including corporate employment policy, retirement patterns, and personal saving. In the past, the system's universal coverage and generous benefits ensured popular support to a degree enjoyed by no other form of "big government" social spending. Yet over two-thirds of all Americans today believe that the social security system will face bankruptcy by the time they retire. The question of social security reform—how to reform the system or whether the system needs reform at all—is the subject of heated debate at all levels of government, in the media, and among workers, pensioners, and employers. Prospects for Social Security Reform informs the debate by exploring why the system is at a crossroads today and what to do about it. Contributors detail the size and nature of the problem, explain views of key "stakeholders" regarding reform options, and report new evidence on how reform might affect the economy. Research findings and public opinion polls are analyzed, as are lessons from other countries experimenting with new ways to deliver old-age benefit promises. No other volume includes as diverse and expert a set of perspectives on reform and privatization as those gathered here from economists, actuaries, employers, investment managers, and representatives of organized labor. Among its chapters is the path-breaking study "Social Security Money's Worth," the 1999 winner of the TIAA-CREF's Paul A. Samuelson Award for Outstanding Scholarly Writing on Lifelong Financial Security.

This book discusses various renewable energy resources and technologies. Topics covered include recent advances in photobioreactor design; microalgal biomass harvesting, drying, and processing; and technological advances and optimised production systems as prerequisites for achieving a positive energy balance. It highlights alternative resources that can be used to replace fossil fuels, such as algal biofuels, biodiesel, bioethanol, and biohydrogen. Further, it reviews microbial technologies, discusses an immobilization method, and highlights the efficiency of enzymes as a key factor in biofuel production. In closing, the book outlines future research directions to increase oil yields in microalgae, which could create new opportunities for lipid-based biofuels, and provides an outlook on the future of global biofuel production. Given its scope, the book will appeal to all researchers and engineers working in the renewable energy sector.

Systems Prospects is a record of the papers presented at the first con ference organised by the United Kingdom Systems Society (UKSS), held at Thwaite Hall, Hull University (UK), on the dates 12th-15th July, 1988. The UKSS originally came together in 1978 as the Barford Group (the first meetings were held in the town of Barford), comprising academics from the four institutions that incorporated departments which primarily were con cerned with developing the theory and practice of so-called systems scienc- namely Aston University, City University, Lancaster University and the Open University. The meetings of the Barford Group were deemed to be successful, so much so that a decision was made to widen its horizons to incorporate more generally those of the United Kingdom systems community (a diffuse number of academics and practitioners) - hence the title UKSS. The society, ten years later, is extant and has achieved new levels of success in the last few years in terms of rising membership and international reputation. The membership is now drawn from a wide variety of academic and commercial and industrial organisations, and from most reaches of the nation. There is also an international contingent in the membership. It is right that there should be such diversity since the UKSS is founded on the notion of equality (of creed, sex, race, class and so on ••• ). This community is "glued" together by the Society's own publication, Systemist, as well as through workshops and now this conference.

Contemporary Systems Thinking is a series of texts, each of which deals comparatively and/or critically with different aspects of holistic thinking at the frontiers of the discipline. Traditionally, writings by systems thinkers have been concerned with single theme propositions such as General Systems Theory, Cybernetics, Operations Research, System Dynamics, Soft Systems Methodology and many others. Recently there have been attempts to fulfil a different yet equally important role by comparative analyses of viewpoints and approaches, each addressing disparate areas of study such as: modeling and simulation, measurement, management, 'problem solving' methods, international relations, social theory and last, but not exhaustively or least, philosophy. In a recent book these were drawn together within a multiform framework as part of an eclectic discussion -a nearly impossible task as I discovered (see Dealing With Complexity -An Introduction to the Theory and Application of Systems Science, R. L. Flood and E. R. Carson, Plenum, New York, 1988). Nevertheless, bringing many sources together led to several achievements, among which was showing a great diversity of approaches, ideas and application areas that systems thinking contributes to (although often with difficulties remaining unresolved). More important, however, while working on that manuscript I became aware of the need for and potential value in a series of books, each focusing in detail on the study areas mentioned above.
