Research ArticleOpen accessIn the abstractImprovement of the Vertical Dispersion of Pollutants Resulting From Chimneys by Thermosiphon EffectA. O.M. Mahmoud, J. Zinoubi, R. B. Maad, A. BelghithThe dispersion of pollutants, resulting from industrial chimneys, in the surrounding atmosphere made the interest in realizing emitting conditions appears. It also encourages the vertical dispersion of these pollutants. At a given wind velocity, the height of this dispersion is essentially a function of the thermal power and the flow rate at the chimney exit. To improve these qualities, we … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstruction of an Integrated Object Oriented System for Temporal GISSouheil Khaddaj, Abdul Adamu, Munir MoradThe development of temporal GIS systems capable of dealing with the evolution of geographical objects is still a challenging task. Although many successful GIS systems have been implemented, comparatively little has been done on how to determine and analyze the patterns of continuous changes of geographical objects. The aim of this paper is to construct a GIS system using an … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,727 accessesView PDFCite
