Covariance and Uncertainty Principle for Dispersive Pulse Propagation

Axioms
We develop the concept of covariance for waves and show that it plays a fundamental role in understanding the evolution of a propagating pulse. The concept clarifies several issues regarding the spread of a pulse and the motion of the mean. Exact results

Application of Effective Conversion Rates between NO and NO₂ in a Standard Airport Dispersion Model System

Atmosphere
The NO/NO2/O3 reaction mechanism of the standard VDI 3783 Part 19 was coupled to the Lagrangian particle model LASAT and quasi-stationary, individual plumes were calculated for a point source under various conditions. First-order conversion rates between

LES CORPS LACUNAIRES DE REVERDY [PDF]

Studii si Cercetari Filologice: Seria Limbi Romanice, 2012
La plénitude est étrangère au monde imaginaire de Reverdy. Son écriture ressasse l’impossibilité d’une emprise stable sur un réel qui demeure inassimilable, inaccessible, sauf à subvertir l’idée du lieu, à défaire l’unité spatiale du corps. De là, un moi
