In this paper, a new structure for image encryption using hybrid cellular automata is presented. The image encryption is done in two steps. At the first step, each pixel is encrypted by rules of hybrid cellular automata. In the next step, each pixel converted to a binary number and each bit is encrypted by rules of cellular automata. The rules are made by a function. Due to reversibility of cel...

there is a new technique to measure total body water named bio-electrical impedance analysis (bia), used in healthy subjects and patients. bia determines the total body water (tbw), fat-free mass (ffm), body cell mass (bcm), extra cellular water (ecw), and intra cellular water (icw) in subjects without significant fluid and electrolyte imbalance. there are several methods such as segmental bia,...

Researchers in bioelectromagnetics often require realistic tissue, cellular and sub-cellular geometry models for their simulations. However, biological shapes are often extremely irregular, while conventional geometrical modeling tools on the market cannot meet the demand for fast and efficient construction of irregular geometries. We have designed a free, user-friendly tool in MATLAB that comb...
