Background: Accurate brain tissue segmentation from magnetic resonance (MR) images is an important step in analysis of cerebral images. There are software packages which are used for brain segmentation. These packages usually contain a set of skull stripping, intensity non-uniformity (bias) correction and segmentation routines. Thus, assessment of the quality of the segmented gray matter (GM), ...

A hypervelocity imperfect gas nozzle with a shared wave-elimination contour is designed by the residual correction method, allowing test Mach number to be varied changing throat contours. Owing effects, classical method of characteristics boundary layer does not produce uniform flow field, resulting in significant deviation from target number. In this work, computational fluid dynamics solver u...
