In order to study the distribution of stress and deformation variable cross-section continuous box girder bridge, in this paper, finite element method is used establish model bridge. Considering layout lane load, combination working conditions calculated, bridge are analysed. The results show that maximum generally occurs at beam span middle section or support, sometimes value vehicle load poin...

We consider fluting oscillations in a thin straight expanding magnetic flux tube the presence of background flow. The is divided into core region that wrapped transitional region, where damping takes place. method multiple scales used for derivation system governing equations. This applicable to study both standing and propagating waves. Furthermore, equations obtained tubes with sharp boundary...

We present a theoretical and experimental study on increasing the sensitivity of ITP assays by varying channel cross-section. We present a simple, unsteady, diffusion-free model for plateau mode ITP in channels with axially varying cross-section. Our model takes into account detailed chemical equilibrium calculations and handles arbitrary variations in channel cross-section. We have validated o...

Many single- and multi-phase fluid dynamical systems are governed by non-linear evolutionary equations. A key aspect of these is that the typically flows across spatially temporally varying cross-sections. We, first, show not any choice state-variables may be apt for obtaining a port-Hamiltonian realization under cross-section. We propose modified then represent in representations. define repre...
