Climate changes caused by global warming has presented challenges to human society. Studying the Changes of climate variables in the future decades by using output data’s of Atmosphere-Ocean Global Circulation Models (AOGCM) is a way of perusing climate fluctuation in a region. In this study, the focus is on the AOGCM proceeds in simulating of variable temperature in Ahwaz and Abadan stations. ...

A method is presented for the systematic design of stabilising decentralised controllers for large-scale interconnected dynamical systems. The design method is based on (i) decentralised implementation of global controllers obtained by using existing global controller design methods, (ii) model reduction of dynamical systems, and (iii) modelling of the interactions among the subsystems comprisi...

The objective of this work is to authenticate individuals based on the appearance of their faces. This is adifficult pattern recognition problem because facial appearance is generally greatly affected by thechanges in the way a face is illuminated, by the camera viewpoint and partial occlusions, for exampledue to eye-wear. We describe a fully automatic algorithm that systematically ...

Résumé : Nous avons mesuré la fréquence de formation de panaches dans une expérience de convection thermique à Pr >>1. Comme la viscosité du fluide utilisé varie fortement avec la température, les couches limites chaude et froide ont différentes épaisseurs et viscosités. Ceci entraîne des fréquences différentes pour ces couches. Il semblerait qu’il y ait une interaction directe entre les couche...

This is a difficult pattern recognition problem because facial appearance is generally greatly affected by the changes in the way a face is illuminated, by the camera viewpoint and partial occlusions, for example due to eye-wear.

In this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. Given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (FSDT). These equations are so...
