U-shape

To examine the influence of board composition on financial performance, the test for Ushaped relationship of Lind and Mehlum (2010) is utilized to find the optimal shareholding structures in Chinese and Taiwanese markets. The results are consistent with the hypothesis that corporate performance is a U-shaped function of the shareholding ratios. This study observes the sensitivity of the related variables about corporate governance, such as education level, board seats, leverage, and firm size, affecting the movement of extreme value in U-shaped relationship.

In the SG (steam generator) of PWR (pressurized water reactor) for a nuclear plant, hundreds of Ushaped tubes are used for the heat exchanger system. They interact with primary pressurized cooling water flow, generating flow-induced vibration in the secondary flow region. A simplified U-tube model is proposed in this study to apply for experiment and its counterpart computation. Using the commercial code, ANSYS-CFX, we first verified the Moody chart, comparing the straight pipe theory with the results derived from CFD (computational fluid dynamics) analysis.
