The non-linearities in waveand slamming-induced rigid-body motions and structural responses of ships such as heave, pitch and vertical bending moments are consistently investigated based on a rational timedomain strip method (Xia, Wang and Jensen, 1998). A hydrodynamic model for predicting sectional green water force is also outlined for the investigation of the effect of green water loads on t...

A system using totally disposable self-supporting bedpans requiring no carrier was examined in use in two hospitals. The bedpans and their contents were disposed of by destruction and flushing to waste carried out in a modified Haigh Sluicemaster disposal unit. This incorporates a positively closing and locking lid with refinements to avoid the lid slamming and has effective safety devices. The...

This paper presents a multi-modal system for finding out where to direct the attention of a social robot in a dialog scenario, which is robust against environmental sounds (door slamming, phone ringing etc.) and short speech segments. The method is based on combining voice activity detection (VAD) and sound source localization (SSL) and furthermore apply post-processing to SSL to filter out sho...

Engineering offshore problems require a continuous progress in the simulation of systems coupling structures and fluids with interfaces. The needs concern complex interface motions and fluid-structure interaction with slamming. The proposed methodology combines, in a parallel message passing algorithm, a level set based interface tracking, a standard finite element projection method on unstruct...

The water-entry problem is a complex multiphase hydrodynamic that directly related to many engineering applications and natural phenomena, such as torpedo airdrops, seaplane landings, ship slamming. Therefore, studying the influence of microscopic properties object surface on macroscopic phenomenon during water entry necessary. In this study, volume fluid model continuum force models are couple...
