In this work we prove that the solution of Serre-Green-Naghdi equation cannot be globally defined when interface reaches impervious bottom tangentially. As a consequence, our result complements paper Camassa, R., Falqui, G., Ortenzi, Pedroni, M., & Thomson, C. Hydrodynamic models and confinement effects by horizontal boundaries. Journal Nonlinear Science, 29(4), 1445-1498, 2019. Furthermore, al...

nowadays, palladium compounds due to their especial characteristics used in different industries, mainly in electrical power sources and chemical productions as a catalyst. therefore, pd concentration is increasing in our around that can be contaminant our environment due its toxic effects. in this work, a simple, selective and rapid flow injection method of analysis (fia) has been developed fo...

A nonlinearly elastic shell is modeled either by the nonlinear threedimensional shell model or by a nonlinear two-dimensional shell model. We show how such two-dimensional shell models can be derived from the minimization problem associated with the nonlinear three-dimensional shell model. For shells made of a Saint Venant-Kirchhoff material, we obtain in particular the nonlinear shell models o...

A wide variety of hydraulic and coastal flows can be modeled using shallow water theories, where the so-called Serre-Green-Naghdi (SGN) equations constitute a fully nonlinear weakly dispersive wave theory that has been successfully applied in fluvial maritime contexts. In present contribution, we show SGN models with wave-breaking parameterizations reproduce challenging processes surf swash zon...

Abstract In our paper, we consider the mixed problem in context of Green-Naghdi theory thermoelastic Cosserat media. Using very accessible mathematical calculations, prove two qualitative results on solutions formulated problem. Thus, first these approaches, obtain a result stability, Hölder type, with regards to loads. second main result, continuous dependence regarding initial values from It ...

the modified surface of typha latifolia l. root (mstl), as an alternative economical adsorbent, wasused for the removal of ni (ii) and cd(ii) ions from aqueous solutions. the effect of initial ph, initialconcentration of metal ion, and contact time was investigated in a batch system at room temperature.the kinetics data could be fitted well by pseudo-second-order model with correlation coeffici...

In this paper, we introduce and analyze discontinuous Galerkin methods for a Naghdi type arch model. We prove that, when the numerical traces are properly chosen, the methods display optimal convergence uniformly with respect to the thickness of the arch. These methods are thus free from membrane and shear locking. We also prove that, when polynomials of degree k are used, all the numerical tra...

In this paper, developed a new multi-product, multi-period, and multi-level closed-loop green supply chain planning model under uncertain conditions. The formulated model consists of five objective functions, which minimize the cost of the supply chain, minimize the CO2 emission of transportation vehicles, maximize the reliability of manufacturing and distribution centers, maximize t...

We consider the issue of wave-breaking closure for well-known Green–Naghdi model and attempt at providing some more understanding sensitivity approaches to numerical set-up. More precisely based on Kazolea Ricchiuto (Ocean Model 123:16–39, 2018), we used two strategies modeling a solitary wave over slope. The first one is hybrid method consisting suppressing dispersive terms in breaking region ...
