Recently, a metal-insulator transition (MIT) was found in the anisotropic Ander-son model of localization by transfer-matrix methods (TMM) [1, 2, 3]. This MIT has been also investigated by multifractal analysis (MFA) [4] and the same critical disorders Wc have been obtained within the accuracy of the data. We now employ energy level statistics (ELS) to further characterize the MIT. We find a cr...

In this paper, optical reflectance properties of an annular photonic crystal (APC) composed alternate layers double negative (DNG) material and a non-magnetized plasma (NMP) layer, immersed in free space, have been theoretically investigated studied. The spectra the PC obtained by employing transfer matrix method (TMM) for cylindrical waves case TEpolarized wave only. It has found that spectral...

Abstract Elastic wave absorption at subwavelength scale is of significance in many engineering applications. Non-Hermitian metamaterials show the ability high-efficiency absorption. However, single functionality an important limitation on their practical applications for lack tunability and reconfigurability. Here, we propose a tunable reconfigurable non-Hermitian piezoelectric metamaterial bar...

In this study, the effect of design parameters such as pipe diameter, wall thickness, material and fluid velocity on natural frequency fluid-structure interaction in straight conveying fully developed turbulent flow were investigate numerically,analytically experimentally. Also support conditions, simply-simply clamped-clamped was investigated. Experimentally, vibrations characterized by accele...

Under unbalanced supply condition low order harmonics will appear at the input and output terminals of the PWM AC to DC converter. Based on the positive and negative sequence components, an unbalanced transfer matrix in terms of the input phase voltages is derived. An on-line method using a neural network (NN) is used to implement this transfer matrix. It is shown that by using an additional lo...

BACKGROUND AND PURPOSE To investigate relationships between the degree of early reperfusion achieved on perfusion-weighted imaging and clinical outcomes in the Diffusion and Perfusion Imaging Evaluation for Understanding Stroke Evolution studies. We hypothesized that there would be a strong correlation between the degree of reperfusion achieved and clinical outcomes in target mismatch (TMM) pat...
