We motivate and analyze a reaction-advection-di usion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity. The light intensity decreases with depth due to absorption by water and phytoplankton. Phytoplankton is transported by turbulent di usion in a water column of given depth. Furthermore, it might be sinking ...

The problem of setting route directives in a motorway network is formulated as a dynamic game problem. After restricting attention to a Nash equilibrium, a search procedure for such an equilibrium is proposed.

The algebraic structure of the set of doubly stochastic circulants is that of a semi-ring. The concept of a prime in the doubly stochastic circulants is introduced in this paper and examples are given. The classiication of a prime in the doubly stochastic circulants is equivalent to the solvability of a linear equation over a doubly stochastic circulant. A representation of doubly stochastic ci...

Section One — Why Rapport Matters In her 1984 review of the literature, Hodgson (as quoted in Ramsden, 2003) wrote that many studies “...underline the vital importance of respect and consideration for students in effective university teaching” (p. 74). Ramsden (2003) supported this conclusion by noting that, “The emotional aspect of the teacher-student relationship is much more important than t...

RÉSUMÉ. Dans cet article, nous proposons un système d’extraction de mots clés dans des documents manuscrits. Notre approche est basée sur la reconnaissance des lignes de texte à l’aide d’un modèle HMM capable de rejeter les mots n’appartenant pas à un lexique prédéfini. Afin d’être plus discriminant, nous avons remplacé les mélanges de gaussiennes des HMM par un réseau de neurones profond pour ...

This article explores two clinical phenomena-pornography and conspiracy thinking-that are highly relevant today and can be observed specifically among adolescent boys in the early stages of post-puberty: conspiracy thinking and the viewing of pornographic videos. It shows that the Lacanian concepts of the Real (of puberty) and the sexual non-rapport help us understand the psychopathological asp...
