Abstract Data modeling requires a sufficient sample size for reproducibility.A small sample size can inhibit model evaluation.A synthetic data generation technique addressing this small sample size problem is evaluated: from the space of arbitrarily distributed samples, a subgroup (class) has a latent multivariate normal characteristic; synthetic d

The present study numerically describes the nature of the arising boundary layer along an isothermal vertical plate, on which is mounted a bluff body.The investigation parameter is the cross-section shape of the bluff body, which includes a square, circular, and prismatic cylinders.To entirely embedded cylinder in the incoming boundary layer, the s

With the development of general aviation, the urban aircraft is around the corner.The urban aircraft with composite is considered as an ultralight vehicle and the crashworthiness is of vital importance for such an ultralight aircraft.Composites are being widely and increasingly used in the aerospace industry because of their advantages that include
