This paper investigates the technique of the modeling and identification a new dynamic NARX fuzzy model by means of genetic algorithms. In conventional identification techniques, difficulties such as poor knowledge of the process, inaccurate process or complexity of the resulting mathematical model, all which limit their usefulness during dealing with dynamic nonlinear industrial processes. To ...

Some of the correlations between morphological and other physical properties of planetary nebulae (PNe) are reviewed. In particular, the finding that bipolar (b) PNe have more massive progenitors than the other morphological classes is discussed in detail. Earlier results are confirmed; including all the various sources of uncertainty, the Galactic distribution of objects indicate that b PNe ar...

are discussed. Many of his views are controversial, but undoubtedly they are most stimulating.

This volume will be invaluable to physiotherapists and their teachers, and it should be read by orthopaedic surgeons and rheumatologists. The product...

Keeping in mind the several models of M(atrix) theory we attempt to understand the possible structure of the topological M(atrix) theory " underlying " these approaches. In particular we raise the issue about the nature of the structure of the vacuum of the topological M(atrix) theory and how this could be related to the vacuum of the electroweak theory. In doing so we are led to a simple Topol...
