“…This extended type of maps enables several real-world problems and spatial patterns to be thoroughly studied, for example, (crystal lattices, Belusov Zhabotinskii reaction, and many others) [4][5][6][7]. As well, the discrete-time chaotic system has various applications in almost most applied sciences branches, and this is due to its ability to describe several situations in real life [8][9][10][11][12][13][14] The 2D logistic map [4] is analyzed on random disturbances. It is proved to possess a variety of regular and chaotic attractors with a complex geometry of the basins of attraction.…”

In this paper, we focused on the coupled logistic map, which is a system of two symmetrically identical single logistic maps. The complicated dynamics of the generated system, which has a wide range of dynamical behavior, grant it much attention for many applications. First, the existence and uniqueness of this system are investigated, where the analytical technique is utilized to find the parametric condition for the local asymptotic stability of its fixed points. It can be obviously seen that it undergoes Niemark-Sacker and Hopf bifurcation in a small neighborhood of the unique positive fixed point and invariant circle. This has been proven based on bifurcation theory and the center manifold theorem. The behavior of this system is stabilized using two conventional controlling methods, the OGY and the pole-placement. As well as, a new control method is proposed to make such stabilization more easier. The numerical simulations are utilized to demonstrate the analytic results.

“…The Sb doped SnO 2 was deposited by different methods involving sputtering, chemical vapor, spray pyrolysis, sol-gel, and electron beam evaporation [15][16][17][18][19]. Spray Pyrolysis deposition method is one of the most significant ways for preparing thin films, this is related to its low cost, simple and easy for thin-film fabrication, and obtaining a high degree of film crystallinity and homogeneity [20,21]. This paper aimed to prepare Sb:SnO 2 with nanoparticles:nanowires structure by spray pyrolysis technique, and with an optimum optical property to exploiting it in the required applications.…”

In this study, the SnO2 nanowires and Sb nanoparticles were synthesized using SnCl4.5H2O and SbCl3 by dissolving them in acetone. The solution was sprayed on a glass substrate via spray pyrolysis route. XRD patterns confirm a polycrystalline film with a tetragonal system. The FESEM analysis of morphology clarified a nanowire structure of SnO2 and nanoparticles structure of Sb. EDX proves that when Sb concentration increase, the SnO2 weight decrease from 72% to 68%. The optical properties have been well investigated by UV-VIS spectrophotometer, from this analysis, it can be observed that the absorbance, reflection, and extinction coefficient increased with the increasing of Sb content. The energy bandgap and refractive index elucidated a reduction with the augmentation of Sb content from 3.92 to 3.8 eV and from 2.24 to 2.22, respectively. The obtained characteristics make these films more suitable for nanoelectronics devices, this is due to their tunable controlling by their amount, and their nanostructures of nanoparticles stick on nanowires which render them more effective for the sensing devices.

“…In addition to its three main properties (sensitive dependence on initial condition, positive Lyapunov exponent, and stochasticity and ergodicity), this property makes it highly influential to be widely used in many applications, including biology, physics, economics, and philosophy. In addition to these necessary fields, it also shows a high impact in cryptography due to its ability to generate pseudo-random sequences to be used as keys in the encryption process [11][12][13][14][15][16][17][18].…”

Chaos theory has attracted much attention because it fully reflects the complexity of the system, which is an essential property in many applications, especially in the optimization problem. In this paper, the possibility of improving research by means of evolutionary algorithms (genetic algorithms) will be discussed which used to solve non-linear programming problems. This improvement and development are carried out using a highly quality chaotic map, which was proposed to be used for generating real values (keys) that are used as reference values for the genetic algorithm. A comparison between the results without using chaotic systems and the results after generating the keys is performed. It shows that the results after the chaotic local search (CLS) are improved and congregate with the optimum value of the solutions obtained by the projected process before the CLS. Moreover, the differences between the proposed systems for improvement are also compared. The evaluation parameters for the proposed chaotic function are developed using the Mathematica 11.2 program.
