— The ship roll stabilization by fin control system with actuator is considered in this paper. Assuming that there exist uncertain parameters and uncertain external perturbations in the ship roll model, a variable structure robust control algorithm for ship roll stabilization system is presented for a class of uncertain systems with the absence of matching(More)
The aim of this study was to investigate the effects of various renal pelvic pressure gradients on nephrons with purulent infection. Five miniature test pigs were selected. One side of the kidney was used to prepare the pyonephrosis model and the other side was used as the healthy control. A piezometer and a water fill tube were inserted into the renal(More)
The character of branching for two chrysanthemum (Chrysanthemum × morifolium) cvs. Jinghai and Jingyun was observed, and the changes of endogenous hormones in apical and lateral buds were investigated to determine the relationship between the pattern of hormone distribution, apical dominance, and lateral bud outgrowth. The growth rate of Jinghai lateral(More)
