Optimum layout of vortex generators for upper surface of wing using efficient global optimization

Nihon Kikai Gakkai ronbunshu, 2015
The “buffet” which is the shock wave vibration on the wing at transonic speed has influence to the aerodynamic performance of the civil transport. It is significant because the wing cannot maintain its aerodynamic performance and it is also led to the ...

Application of a semivariogram based on a deep neural network to Ordinary Kriging interpolation of elevation data.

PLoS ONE, 2022
The Ordinary Kriging method is a common spatial interpolation algorithm in geostatistics. Because the semivariogram required for kriging interpolation greatly influences this process, optimal fitting of the semivariogram is of major significance for ...
