Pressure Drop through Metallic Foam Authored by Ahmed Kouidri, The metallic foam presents a positive impact in fluid engineering; moreover, the latter can presents also a significant pressure drop which was the aim of several studies. Boomsma et al. [1] studied experimentally the influence of compressibility and pore scale, they found that the increasing in compressibility factor decrease the permeability, and the latter will be more sensible in front of permeability. Dukhan et al. [2] demonstrated that the pressure drop, in quadratic form, increase with increasing in pore density (PPI). They make also a new correlation that link the permeability with the inertial coefficient. We note that Guarino et al. [3] reported the same remark. The experiences of Manchin et al. [4] demonstrated that the pressure drop increase with decreasing in relative density (defined as the metallic foam density per material density). Concerning the metal foam made from copper, the work of Xianbing...

A Method of J-M Distance Based "salt-and -pepper" Noise Removing Authored by Jian Wu This paper deals with the salt-and-pepper noise existed in the classified satellite images based on the spectral similarity which is identified by the Jeffries-Matusit (J-M) distance. An increased order of J-M distances for the collected samples of the land use/cover (LUC) types are established, the LUC type with the least J-M distance pair separation is chosen and whose patches area less than the minimum mapping unit (MMU) are combined to the other LUC type of the pair.
