Evolutionary programming approach for securing medical images using genetic algorithm and standard deviation
The integrity and security of medical data have become a big challenge for healthcare services applications. Images of hidden text represent
steganography forms in which the image is exploited as an object to cover
information and data. So, the…

Patch antenna design based on 1D-EBG structures for high gain applications
In this paper the band gap of one-dimensional electromagnetic band gap (1D-EBG) structures will be determined analytically using the dispersion
diagram method. Next, we propose a 1D-EBG antenna design to improve the directivity at 3.5 GHz for WiMax…

Combination time-frequency and empirical wavelet transform methods for removal of composite noise in EMG signals
Electromyography (EMG) is a technique used to measure the electrical
activity in muscles during movement. Doctors commonly employ this method to quickly evaluate and identify conditions such as muscle problems, dystrophy, and neuropathies. The main…

Efficient 2D NZCC/MD code for SAC-OCDMA systems based on direct spectral/spatial dimension detection and WF
One dimensional (1D) spectral amplitude coding-optical code division
multiple access (SAC-OCDMA) systems are generally known by a strict
limitation in the number of users that can simultaneously connect. A main
solution to overcome this drawback…
