A High Order Approximation of the Two Dimensional Acoustic Wave Equation with Discontinuous Coefficients
This paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. The method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions. The construction of the nonstandard method is based on the special treatment of the interface using suitable jump conditio...
متن کاملDamage identification of structures using second-order approximation of Neumann series expansion
In this paper, a novel approach proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). As the number of sensors used to measure modal data is normally limited and usually are less than the number of DOFs in the finite element model, the model reduction approach should be used to match with incomplete measured mode shapes. The second-order a...

متن کاملEmergent Behavior in a Low-Order Fluidized-Bed Bubble Model
Low-order models are becoming increasingly useful for simulating the complex collective behavior arising in large dynamical systems. Modeling of traffic flow and the behavior of biological systems such as ant colonies and bird flocks are commonly referenced examples of this new approach. We have explored the application of this type of model to describe the dynamics of voids in bubbling fluidiz...
متن کاملA numerical solution of variable order diusion and wave equations
In this work, we consider variable order difusion and wave equations. The derivative is describedin the Caputo sence of variable order. We use the Genocchi polynomials as basic functions andobtain operational matrices via these polynomials. These matrices and collocation method help usto convert variable order diusion and wave equations to an algebraic system. Some examples aregiven to show the...
