A new proposed technique with noninvasive ultra wide-band (UWB) for tumor cancer detection is investigated. The 2-Dimensions finite difference time domain (FDTD) model is used to simulate the scattered electromagnetic wave from the breast model. The skin backscattering and reflections from surrounding environments is reduced using a new algorithm.(More)
A 6-mm resolution 7-tissue (skin, blood, bone, muscle, gray matter, white matter, air) anatomy based model (62times62 cells) cross section of human head is studied. Four dipoles of a 64 MHz is applied. A neuro-fuzzy modeling of the head is presented. A system that describes input-output behavior in a way similar to mathematical mapping without involving(More)
Dielectronic recombination (DR) cross sections and rate coefficients are calculated for the isonuclear sequence FeZ+, with Z = 21, 20, 19, 18, 17, and 16, in which L-shell (2p-) excitations are involved during the initial capture. Most of the dominant transitions with ∆n = 0, using angular momentum average (AMA) approximation, are considered. It is found(More)
