Abstract: The barotropic shallow-water equations and exponential topography are used to investigate the low-frequency scattering of an incident shelf wave by a thin barrier located parallel to the coast by means of eigenfunction ...

Abstract: The natural cation in Wyoming bentonite is exchanged with Tetramethylammonium

Abstract: A methodology to minimize blade secondary losses by modifying turbine end walls is presented. The optimization is addressed using a gradient-based method, where the computation of the gradient ...

Abstract: A new formulation of the mixing plane boundary condition to analyze the steadystate interaction between adjacent rows of a turbomachine, used in conjunction with steady twodimensional nonreflecting boundary conditions, is ...

Abstract: The mechanism method, based on the particularization of limit design to masonry structures proposed by Heyman, is certainly a very suitable procedure for the analysis of no-tension material arches, especially because of ...

Abstract: The complex dynamics of a pendulum controlled by a Proportional-Derivative (PD) compensator are analyzed. A classification of equilibrium points and the characterization of their bifurcations is ...

Abstract: This work addresses a method for location of a wave source by observing the wave as it reaches various observation points (receivers), or conversely, this is also a method for location of a ...

Abstract: An assumed strain approach for a linear triangular element able to handle finite deformation problems is presented in this paper. The element is based on a total Lagrangian formulation and its ...

Abstract: In this work, a novel procedure to solve the Navier-Stokes equations in the vorticity-velocity formulation is presented. The vorticity transport equation is solved as an ordinary differential ...

Abstract: The effect of the finite extent of linear cascades on the unsteady pressure distribution of vibrating blades is assessed by means of a numerical study. The span of a reference cascade made ...
