Non-reflecting Boundary Conditions for Wave Propagation Problems
We consider two aspects of non-reflecting boundary conditions for wave propagation problems. First we evaluate a proposed Perfectly Matched Layer (PML) method for the simulation of advective acoustics. It is shown that the proposed PML becomes unstable for a certain combination of parameters. A stabilizing procedure is proposed and implemented. By numerical experiments the performance of the PM...
متن کاملAbsorbing Layers and Non-Reflecting Boundary Conditions for Wave Propagation Problems
The presence of wave motion is the defining feature in many fields of application,such as electro-magnetics, seismics, acoustics, aerodynamics, oceanography and optics.In these fields, accurate numerical simulation of wave phenomena is important for theenhanced understanding of basic phenomenon, but also in design and development ofvarious engineering applications.In general...
متن کاملLove Wave Propagation in a Fiber-reinforced Layer with Corrugated Boundaries Overlying Heterogeneous Half-space
Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...
متن کاملA Constraint-Propagation Approach to Probabilistic Reasoning
The paper demonstrates that strict adherence to probability theory does not preclude the use of concurrent, self-activated constraint-propagation mechanisms for managing uncertainty. Maintaining local records of sources-of-belief allows both predictive and diagnostic inferences to be activated simultaneously and propagate harmoniously towards a stable equilibrium.
متن کاملA Probabilistic Approach to Marker Propagation
Potential ly, the advantages of marker-passing over local connectionist techniques for associa t ive inference are (1) the abi l i ty to differen t iate variable bindings, and (2) reduction in the search space and/or number of processing elements. However, the latter advantage has mostly been realized at the expense of accu racy and predictabi l i ty. In this paper we con sider a class of a...
