In this paper a comparative study of two different control strategies is done: Gain scheduling with classic controllers (PD and second order filter) versus QFT. Both of them are used to decrease motion sickness in a high speed ferry produced by the vertical acceleration associated with heave and pitch motion. Copyright  2002 IFAC

We present dye visualizations of the wake behind a flexible plate flow when its leading edge is forced into harmonic heave motion. We show that, when the forcing amplitude is sufficiently large, a reverse Bénard-von Kármán vortex street is formed in the wake, indicative of the production of positive thrust.

The base of solar collector systems is usually installed in soil that contains moisture. In cold regions, due to the low ambient temperature, moisture freezes, creating a risk frost heave. This study analyzed heave mechanism power transmission and transformation foundation, clarified factors affecting way solve layer heave, proposed use heat transfer elements pre-frozen layers prevent foundatio...

This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...
