Digital steganography is the art of hiding secret messages and data in innocent cover, most likely in images and videos. Images and videos offer the best cover files for steganography with their high capacity, by being innocent and for being easily…

The problem of mal operation of differential protection of power transformer due to the inrush magnetizing current has long considered as a challenging problem. Several types of protection relays have been used to solve the issue (basic relay,…

The advent of nodal elements, such as Optical Add/Drop Multiplexers (OADM) for Wavelength Division Multiplexed (WDM) networks, has led to a myriad of possible network architectures for the optical layer. In this project we design and simulate a…

In recent years a trend of using CubeSat-class nanosatellites for commercial and scientific missions has taken the lead; this is due to the advantage of the available and low-cost products on the market without need for a large development and…

In this paper, we have presented the 3D cables parallel robot in pyramid’s form. The dynamic equation has been established including the dynamic behavior, in this context; we investigated to use the Runge Kutta method of 4th order to solving…

This research paper presents a relevant contribution to optimal control of angular velocities with trajectories tracking for 2WD mobile robots. The dynamic model of each robotic servomechanisms is modelled from experimental data as a second order…

This paper presents the application of fractional order operators to improve the control quality of multivariable systems. The basic ideas of this tuning method are based, in the first place, on the existed tuning methods for setting the parameters…

Distillation column is very important and high consuming energy equipment in oil refineries, such that 3% of the energy consumption in the world is allocated in distillation column. The fact that let controlling the distillation column an attractive…

The present article aims to investigate and evaluate the performances of DWDM (or Dense Wavelength Division Multiplexed) system under MIMO-FSO (or multiple input multiple output-free space optical) channel. However, the proposed system is configured…

Usually the design of microstrip filters is done using simulators and classical approximation methods as Butterworth and Chebyshev, these techniques takes a lot of time to run for designing filters. In this paper we develop a faster artificial neural…
