We present a modeling technique for the interaction of an elliptical-shape crack in a metal with an open-ended waveguide. The crack is first modeled by an appropriate number of short rectangular waveguides. The mode-matching technique is then used to calculate the scattering matrix of the new segmented waveguide structure. The probe reflection coefficient of the dominant mode is finally calcula...

The objective of this paper is to recognize human actions in still images. The contribution of this work is a novel framework for obtaining weak alignment of human body-parts to improve the recognition performance. Our framework implicitly exploits physical constraints of human body parts (e.g., heads are above necks, hands are attached to forearms). It uses the locations of some detected body ...

COMSOL Multiphysics software is used to describe the behavior of electrical resistivity several samples with rectangular shape typically in Montgomery method. The simulation data obtained using four isotropic conductors allowed us understand detail electric potential and field samples. results provide an analytical method which can substitute four-probe much more simplicity precision.

Abstract In this study, we introduce a new rotating uniform eddy current (RUEC) probe designed to identify artificial cracks in conductive materials. The RUEC comprises four rectangular coils, divided into two sets of diagonally positioned coils. By providing alternating sources with 90° phase difference the distribution amplitude all directions can be produced on surface test specimen. Further...

In this paper effects of coaxial probe feeding position and its penetration inside the radiating structure of an antenna has been presented in detail. For this purpose, a Rectangular Dielectric Resonator Antenna (RDRA) has been synthesized and analyzed. There effects on the characteristic behavior of antenna have been obtained. Optimized condition is established and relation between probe dimen...
