Background: Alzheimer’s disease (AD) is the most dominant type of dementia that has not been treated completely yet. Few Alzheimer‘s patients are correctly diagnosed on time. Therefore, diagnostic tools are needed for better and more efficient di

This paper aims to improve SHA-512 security without increasing complexity; therefore, we focused on hash functions depending on DNA sequences and chaotic maps. After analysis of 45 various chaotic map types, only 5 types are selected in this proposal

This paper proposes a novel design of a software-defined matched filter (MF) for digital receivers of synthetic aperture radar (SAR). The block diagram of the proposed receiver is described in detail. The purpose of this filter is to produce a SAR pu
The fundamental issue limiting long-distance and high-speed optical fiber transmission is dispersion. Dispersion impairs system performance, the signal-to-noise ratio (SNR), and the bit error rate (BER). To address this, numerous dispersion modificat

Dispersion is the main problem that limits long-distance and high-speed optical fiber transmission. Bit error rate, the signal-to-noise ratio, and system performance all suffer from dispersion. Many dispersion adjustment strategies have been created
