Abstract: Internal flows of compressible fluids in nozzles and constant-area channels subjected to constant axial acceleration or gravitation are examined in detail. It is found that the effect of nozzle ...

Abstract: An active mass driver has been designed for installation on the upper observation deck of the 310 m Nanjing TV transmission tower in China in order to reduce the acceleration response under strong wind gusts. In this paper, ...

Abstract: Control methods based on the theory of variable structure system or sliding mode control are presented for applications to seismically excited nonlinear and hysteretic civil engineering structures. These control methods ...

Abstract: Continuous sliding mode control (CSMC) methods, which do not have an undesirable chattering effect, are presented for applications to seismically excited linear structures. These control methods are robust with respect to ...

Abstract: Three Archimedean copulas were employed to model annual maximum flood peak data of different lengths. Estimation methods based on ranks were employed for parameter estimation. Marginals were modeled with the generalized ...

Abstract: Recently,

Abstract: Based on the theory of continuous sliding-mode control, control methods are presented for seismic-excited buildings isolated by a frictional-type sliding-isolation system. The dynamic behavior of the building equipped with ...
