Professional ethics assigns some duties to the organization of religion propagation from which approaches to innovative fields could be mentioned. This study investigates “religious propagation” and claims that nowadays, without entering the innovative scientific fields, religious propagation would not meet success. Emergence of organization of religion propagation to the modern sciences such a...
Study of the beam propagation behavior through oceanic media is a challenging subject. In this paper, based on generalized Collins integral, the mean irradiance profile of Gaussian laser beam propagation through ocean is investigated. Power In Special Bucket (PIB) is calculated. Using analytical expressions and calculating seawater transmission, the effects of absorption and scattering on beam ...
Normally, the communication in the earth surface is through electromagnetic or radio waves. But this is not possible in the underwater environments in an efficient way. In underwater environments radio does not work well due to its quick attenuation in water. Hence the acoustic signals are sent using the acoustic channels. If the communication is done with retransmission, it gives rise to the p...
