Probing the buckling of pressurized spherical shells

Pedro Miguel Nunes Pereira de Almeida Reis, Dong Yan, Arefeh Abbasi

The prediction of the critical buckling conditions of shell structures is plagued by imperfection sensitivity. Non-destructive testing through point-load probing has been recently proposed to map the stability landscape of cylindrical shells. However, the ...

Preliminary Study on the Influence of an Air-Bubble Screen on Local Scour around a Bridge Pier

Anton Schleiss, Violaine Dugué, Sylvain Rigaud, Elham Izadinia

Flow interactions with a bridge pier and movable river bed result in local scour which can endanger bridge pier foundations. This scour is initiated by the downward flow and amplified by the so-called horseshoe vortex. A new method to reduce scouring aroun ...

Application of the minimum state error variance approach to nonlinear system control

Ljubisa Miskovic

A class of modified state space self-tuning controllers of the minimum state error variance type was considered. A suitable chosen structure of the proposed controller allows the tracking of a time-varying reference input and makes it possible to apply thi ...
