Ellipses and cylinders are foundational to drawing forms in perspective. This short shares a practical method to improve accuracy, consistency, and confidence when drawing rounded forms—making complex ...

Abstract: In this paper, we propose a method for eliminating the phantom shell effect using negative permittivity material. The absorbed power density (APD) distribution in the phantom provided by IEC ...

Abstract: The hydrodynamic noise radiated from a circular cylinder can be reduced effectively by controlling the flow field. A bionic method proposed in this study is one of the flow control methods.
