We present the new version of the Graphics Recognition Module developed within the Machine Drawing Understanding System (MDUS) for the graphics recognition contest, to be held during the second IAPR Workshop on Graphics Recognition, Nancy, France, 1997. A generic integrated graphics recognition algorithm is adapted to meet the requirements of the contest: straight and circular, solid and dashed...

The membrane gas separation process has gained significant attention using the computational fluid dynamics (CFD) technique. This study considered CFD method to find concentration profiles in a hollow fiber (HFM) module separate binary mixture. was with thickness where each component’s mass fluxes could be obtained based on local partial pressures, solubility, diffusion, and membrane’s selectiv...

Onboard air separation devices, based on hollow fiber membranes, are traditionally used for the optimization of aircraft fuel tank inerting systems. In present study, a set tests have been designed and executed to assess performances these systems different inlet temperatures (70°C∼110°C), pressures (0.1∼0.4 MPa), volume flow rates nitrogen-enriched (NEA) (30∼120 L/min) flight altitudes (1.5∼18...
