In 1961, D. R. Daniel observed that the success of a company is usually determined by three to six major factors. This observation has led to many successful management ideas, but they leave one puzzled: why three to six? why not two or seven? In this paper, we provide a possible explanation to this puzzle; namely, we show that these numbers of factors can be derived from Zipf’s Law and from th...

We give an alternative proof of a theorem of Gustafson and Seddighin (1993) following the idea used by Das et al. in an earlier study of antieigenvectors (1998). The result proved here holds for certain classes of normal operators even if the space is infinite dimensional.

Résumé Dans cet article nous allons présenter une méthode pour la détection automatique d’objets artificiels dans des images numériques représentant des milieux naturels. Cette méthode est basée sur la distribution statistique des motifs de texture dans l’image. Cette distribution est calculée en utilisant la loi de Zipf. L’image est divisée en imagettes et la distribution de Zipf est calculée ...

The 30-year history of quasicrystals is one in which, time after time, the conventional scientific view about what is possible has been proven wrong. First, quasicrystals were thought to be mathematically impossible; then, physically impossible; then, impossible unless synthesised in the laboratory under carefully controlled conditions. One by one, these strongly held views have been disproven,...
