The effectiveness of the two-dimensional electric potential method of damage sensing in a quasi-isotropic carbon fiber polymer–matrix composite depends on the electrical configuration, i.e., the current direction relative to the surface fibers and the electrical contact scheme. Oblique current application in any direction provides effective damage sensing, as shown by using electrical contacts ...

presently, emerging economies are acquiring singular positions all over the world. the complexities of nowadays economy have caused international companies and investors to be of a tendency towards emerging markets for more profitability and growth. this study aims to find the relationships between firm's profitability and growth in iranian manufacturing industry consisting of tehran stock...

Direction-of-arrival (DOA) estimation based on the array of three-component electromagnetic vector-sensors is considered within a biquaternion framework. A relationship is established between the biquaternion covariance and the combination of both complex covariance and cross-product. By exploiting this relationship, the DOA estimates can finally be obtained by diagonalizing the biquaternion co...

High-frequency (HF) radars are routinely used for remotely sensing ocean surface currents. However, the performance of the most widely used direction-finding HF radar is degraded due to the effect of the inevitable deviations of actual antenna pattern on the direction of arrival (DOA) estimation. In this paper, we quantify the DOA estimation error resulting from the deviation of the actual ante...

A meshless numerical technique is proposed for solving the generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system with electromagnetic fields. The employed meshless technique is based on a generalized smoothed particle hydrodynamics (SPH) approach. The spatial direction has been discretized with the generalized SPH technique. Thus, we obtain a system of ordinary...
