Free-space optical communication systems are gaining popularity as a high-capacity, cost-effective and license-free wireless technology, addressing the bandwidth demands of existing and future wireless networks. The deployment scenarios of free pace optical links usually concern secure, fast and reliable connections. Thus, in this work, the performance of optical wireless communication systems is...
In this work we investigate the combined detrimental impact of atmospheric turbulence and spatial jitter, i.e. pointing errors, effects on the performance of a terrestrial free space optical (FSO) system, by taking into consideration several time diversity schemes and the time dispersion of the longitudinal optical chirped pulses which are employed. The scintillation effect is modeled through the...
In the last three decades a growing interest in developing nonlinear dynamical systems for economic models, displaying chaotic behavior has been developed. To this direction, a novel 3-D nonlinear finance chaotic system consisting of two nonlinearities is presented. The dynamical analysis of the proposed system confirms its complex dynamic behavior, which is studied by using well-known simulation...
Today many scientists see nonlinear science as the most important frontier for the fundamental understanding of Nature. Especially, the recent implementation of the memristor has led to the interpretation of phenomena not only in electronic devices but also in biological systems. Many research teams work on projects, which use memristor to simulate the behavior of biological synapses. Based on this...
