Finite element technology in one-dimensional layered media of the continuous electro-media and the two-dimensional continuous electrical is displayed in ways of the special matrix equations in the variation formula and split technical conditions. To achieve a one-dimensional layered continuous electrical finite element numerical simulation of the media, the introduction of the secondary triangu...

The present paper deals with the generation of Love waves in a layer of finite thickness over an initially stressed heterogeneous semi-infinite media. The rigidity and density of the layer are functions of temperature, i.e. they are temperature dependent.  The lower substratum is an initially stressed medium and its rigidity and density vary linearly with the depth. The frequency relation of Lo...

Utilizing invisible 2-dimensional codes and digital audio players with a 2-dimensional code scanner, we developed two types of new auditory testing media. The result of experimental evaluation of the new testing media shows that, in addition to existing special accommodations such as large-print-format test and braille-format test, the introduction of the new auditory testing media enables all ...

We present a non-perturbative technique to study pulse dynamics in excitable media. The method is used to study propagation failure in one-dimensional and twodimensional excitable media. In one-dimensional media we describe the behaviour of pulses and wave trains near the saddle node bifurcation, where propagation fails. The generalization of our method to two dimensions captures the point wher...

Utilizing invisible 2-dimensional codes and digital audio players with 2-dimensional code scanner, two types of new auditory testing media were developed in our previous works. This paper presents the result of experimental evaluation of the new testing media. The result shows that, in addition to existing special arrangements such as large-print-format test and braille-format test, the introdu...

The perfectly matched layer (PML) constitutive tensors that match more general linear media presenting bianisotropic and dispersive behavior are obtained for single interface problems and for two-dimensional (2-D) and three-dimensional (3-D) corner regions. The derivation is based on the analytic continuation of Maxwell’s equations to a complex variables domain. The formulation is Maxwellian so...

it is well established that the seismic ground response of surface topographies may differ from those of free field motion during earthquakes. complex nature of seismic wave scattering by topographical structures can only be solved accurately and economically using advanced numerical methods under realistic conditions. among the numerical methods, the boundary element is a powerful numerical te...
