Solutions and Simulation in Applied Sciences
Dr. O. C. Zienkiewicz, CBE, FRS, FEng. is Professor Emeritus and Director of the Institute for Numerical Methods in Engineering at the University of Wales, in Swansea. He holds the UNESCO Chair of Numerical Methods in Engineering at Technical University of Catalunya, Barcelona, Spain, and the Joe C. Walter Chair of Engineering at the University of Texas at Austin.
He was born in England, attended Primary and Secondary Schools in Poland, and obtained his BSc, PhD and DSc at Imperial College, London, England. He has received may honorary degrees including ones from Ireland, Belgium, Norway, Sweden, China, Poland, Scotland, Germany, France, England, Italy, Hong Kong, Hungary and the United States. He has also received many special honors and medals including the title of Commander of the British Empire and the Royal Medal from HM Queen Elizabeth II, the 'Carl Friedrich Gauss' medal of the West German Academy of Science, the Nathan Newmark Medal of the Americal Society of civil Engineers, the James Alfred Ewing Medal of the Institution of Civil Engineers, (UK), the Worcester Warner Reed Medal of the American Society of Mechanical Engineers, the Newton- Gauss Medal at the International Association for Computational Mechanics, the Gold Medal of Institution of Structural Engineering and the Gold Medal of the Institution for Mathematics and its Applications. He was elected to the Royal Society and the Royal Academy of Engineering in 1978 and is a Foreign Member of the United States National Academy of Engineering and of the Polish Academy of Science.
His contributions range over the wide field of mechanics and engineering. Since his first paper in 1947 dealing with numerical approximation to the stress analysis of dams (using relaxation and finite differences) he has published some 450 papers and written or edited 25 books.
He is one of the early pioneers of the finite element method and the first to realise its general potential for solution of problems outside the area of solid mechanics. His books on the Finite Element Method were the first to present the subject and remained unchallenged till 1972 when many others entered the area. (The Finite Element Method in Structural Mechanics, McGraw Hill, 1967 (272 pp); The Finite Element in Engineering Science, McGraw Hill, 1971 (521 pp). The later editions of the book [The Finite Element Method III, McGraw Hill 1977 (787 pp) and The Finite Element Method IV, with R. L. Taylor (2 vols. pp 1400) McGraw Hill, 1989/91] remain today the standard reference texts.
Dr. Zienkiewicz has, with his team of researchers, contributed many fundamental developments of the method which today make it the widely applicable tool of computational mechanics and engineering. Among these special mention can be made of isoparametric element forms, thick plate/shell formulations and use of reduced integration, penalty forms, treatment of hyperbolic convection equations and of incompressible and compressible fluid mechanics, and more recently of error estimates and adaptive refinement.
In his research career, he has personally supervised some 70 PhD students, many of whom today hold leading positions in the Academia and industry He founded the first journal dealing with computational mechanics in 1968 (Int. J. Numerical Methods in Engineering) of which he is the Editor. this today is still the major journal for the field of Numerical Computations.
He is a founder member of the French Association of GAMNI and of the International Association of Institutional Computational Mechanics of which he was the first President (1986-90). He served as member of Council of the institution of Civil Engineers, UK, and was the Chairman of the Analysis and Design Committee of the International Congress for Large Dams.

Fuzzy Systems Modelling
The phenomenon of fuzzy sets, amplified by their numerous applications, has triggered a significant amount of interest among research communities, as well as practitioners in many areas including engineering, ecology. economics, administration, and business. What is the role of fuzzy sets? When they should be used? And it has even triggered more intrguing queries: why do they work? what are good design practices? Those are the instances of several frequently asked questions being posed before the investment of time and money into this area. Some of these questions have already been answered in the existing literature. The answers to the others are not available since some of the questions have yet to be posed in a straightforward manner.
Uncertainty - A Key to
Better Understanding of Systems
The presentation will highlight the role of uncertainty in facilitating progress in systems modelling and simulation. Far from being an admission of failure, uncertainty based reasoning helps to reduce the complexity of systems and to increase the credibility of their models.
The lecture will provide examples of various physical and engineering systems, ranging from galaxies and star clusters to urban traffic systems, and will discuss the relevance of various aspects of uncertainty that are pertinent within the context of these systems. It is argued that the recent research into the meaning of uncertainty as a multi-dimensional entity has refined the intuitive and philosophical notions that have withstood well the test of time.
Interactions in Complex Traffic Systems
The presentation gives an overview of the past history and present development trends in computer simulation of traffic systems.
Basically, the four driving forces behind the forty years development of traffic simulation are 1) the advances in traffic theory, 2) in computer hardware technology, and 3) in programming tools, and 4) the society's demand for more detailed analysis of the consequences of traffic measures and plans.
Traffic theory itself has advanced in many fields, and it has also learned from other fields resulting to new approaches like soft computing and cellular automata in traffic simulation. Hardware development, in turn, has lead to increasing use of graphics and to simulation of city or corridor wide networks and traffic systems. New programming techniques, like object-oriented programming and virtual reality systems are coming to common use. Integrated use of several programs and the applications of parallel computing and GIS databases are also results of hardware and software technology developments.
In all, the basic application areas of simulation have mainly remained the same through decades, but the applications have grown in size and complexity. In 1990'ies demand analysis through simulation has emerged as a new application area. In the future, interactive simulation systems give new approaches to research in traffic safety and transport telematics. Simulation systems interact either with human beings like the users of the traffic system or with other technical systems like traffic control and information systems.
Humans as the centre of
clothing design simulation
Traditionally people have been created as humanoids using a variety of 3D software tools. Without exception these have lacked realism. A variety of technologies are now available to capture human data. The most exciting ones take '3D photographs' which show a wealth of detail. The resulting computer graphics can be used as mannequins in 3D environments and are of special interest to the apparel design community.
The research programme at Nottingham Trent University is showing how the 'fit' of garments can be assessed using these technologies and how data can be shared across distributed environments. The concepts are of great value to retailers planning their shop layouts and to buyers determining the products to be offered. Realistic human mannequins representing the true shape of the population are enabling a wealth of opportunities to use simulation techniques to improve business efficiency.
