The shallow water equations fall into the category of systems of conservation laws which can be symmetrized thanks to the existence of a mathematical entropy coinciding, in this case, with the total energy.
The results obtained are very important for those involved in the development of modelling tools and systems, for requirement analysis and to provide insight on new features and trends for this category of systems.
The winner is EDS Chairman Lester M. Alberthal Jr., for: "We've decided that the best way to meet the priorities and needs of our clients is through a portfolio of related service offerings that cut across the categories of systems and technology services, business process management.... ..... Close second in above category.
Then, a taxonomy is put forward for system adaptations and the concept and architecture are presented for each category of system adaptations.
It belongs to the self-optimization category of system performance guaranteeing.
In this paper, we present taxonomy of MANET name systems based on their architecture and specify the operations that each category of name systems should support.
Explanations in terms of how the categories of systems are organised to function in ever changing conditions are more revealing.
The study of the first category of systems shows that code-designed buildings may exhibit only a moderate increase in displacement and ductility demand if the load-resisting elements have a purely elasto-plastic behaviour.
On the contrary, the study of the second category of systems reveals that the shifting of resistance centres due to asymmetrically localized yielding of load-resisting element at one edge under coupled lateral-torsional motion, and the progressive deterioration of strength of this edge element, may cause a displacement and ductility demand several times those of the similar symmetric systems.
In any case, given the great potential uses of a system of categories (many of which do not depend on claims that that category system is uniquely acceptable), we should not abandon attempts at systems of categorization prematurely.
Multiplicity characterizes an emerging category of systems in which diverse groups of humans work together with diverse groups of machines to solve difficult problems, consistent with the points made by Markoff and Mindell.
