Data fusion, the ability to combine data derived from several sources to provide a coherent, informative, and useful characterization of a situation, is a challenging task. There is no unified and proven solution which is applicable in all circumstances, but there are many plausible and useful approaches which can be and are used to solve particular applications. This volume presents the proceedings of the workshop Data Fusion Applications hosted in Brussels by the 1992 ESPRIT Conference and Exhibition. It contains 22 papers from 69 experts, who present advanced research results on data...

1. Facts: A leisure term with an unbounded value function, when added to utility in the Lucas (1988) 'mechanics of economic development', expands enormously the range of data covered by the theory. To explain this we have to ask two questions. First: why leisure would be so much desired? Perhaps because leisure is one's own time and such a leisure term means an unbounded value of individual freedom. But why leisure is economically productive, as implied by the results obtained in this study? Perhaps because cognitive innovations often occur during the time which in economics is registered as...

Viscoelasticandtransportpropertiesofpolymersintheliquid(solution, melt)or liquid-like (rubber) state determine their processing and application to a large extent and are of basic physical interest 1 3]. An understanding of these dynamic properties at a molecular level, therefore, is of great importance. However, thisunderstandingiscomplicatedbythefactsthatdi?erentmotional processes may occur on di?erent length scales and that the dynamics are governed by universal chain properties as well as by the special chemical structure of the monomer units 4,5]. The earliest and simplest approach in...
