This paper describes an experimental work on the electrical characterization of commercial LED of different colors and their photoelectric effect. A research work has been carried out to develop the experimental measurement in order to show the…

This paper presents a combined sliding mode space vector modulation control of the shunt active power filter using robust harmonic extraction method to improve the power quality such as current harmonics and reactive power compensation due to the…

In this paper, we present a software development of multimedia streaming encryption using Hyperchaos-based Random Number Generator (HRNG) implemented in C#. The software implements and uses the proposed HRNG to generate keystream for encrypting and…

In this work, we study vector control and sliding mode control of series-connected five-phase two asynchronous machines supplied with a three levels inverter. After presentation of multiphase machines, we worked out the mathematical model of five…

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,…

Empirical mode decomposition (EMD) is a powerful algorithm proposed to analysis of nonlinear and non-stationary signals. The phenomenon of mode mixing is one of the major disadvantages of the EMD. The Ensemble EMD (EEMD) was introduced to eliminate…

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…

Steganography is one of the oldest methods of secure communication. It was an art at the beginning, now became a science. It aims to conceal secret messages or data inside an innocent cover. Steganalysis is the science that can detect and extract…

The analysis of the human behavior from video is a wide field of the vision by computer. In this work, we are presenting mainly a new approach and method of detects behavior or abnormal events continuous of crowd in the case of the dangerous…

Antenna arrays are considered as important type used today for long distance communication with a very high gain. The design of such antenna depends on parameters and desired behavior performing the task, this project handle the application of a new…
