In this article, we develop an innovative series representation for the sum of Rician non-zero boresight pointing error random variates based on the ${\bm{\kappa }} - {\bm{\mu \ }}$distribution, which is suitable for multiple-input multiple-output (M

This study investigated the effect of salinity on the anatomical features of date palm (Phoenix dactylifera L.) and the potential roles of nano selenium (Se NPs) in alleviating the adverse effects of salinity. Two concentrations (80 and 160 mg.L-1) o

An analytical procedure has been carried out to measure the charge that may be trapped in an insulator sample of scanning electron microscope. It mainly concerns the determination of the deduced polarization charges by means of mirror effect phenomen

The process of examining and analysing insulating materials using a scanning electron microscope usually accompanied by an important phenomenon called the mirror effect or charging effects. Such effects arise due to the ability of insulators to trapp
The current study used the Fourier Transform Infrared (FTIR) spectroscopy to determine the corresponding changes caused by salt-induced biochemical changes at different NaCl concentrations (2.5 as control level, 5, 10, and 20 ds.m− 1). FTIR also de

The article discusses the features of narrow-band processes at the output of the amplitude detector. Much attention is paid to the appearance of phase jumps by π when the signal envelope passes through zero and their disappearance, since the use of

Accumulation of charges (electrons) at the specimen surface in scanning electron microscope (SEM) lead to generate an electrostatic potential. By using the method of image charges, this potential is defined in the chamber's space of such apparatus. T

In this paper, an exact errors rate analysis of the hybrid free-space optical/radio frequency (FSO/RF) system based on combining diversity is presented. The system’s errors rate is analyzed under the effects of the atmospheric turbulence, foggy wea
