One can use that methodology in the more complex environment of the plasma and can obtain a straightforward approach toward his studies. We have studied different parameter impacts on the linear and nonlinear modes of the ITG by using data from tokamak plasma. Hence, our study is related to the tokamak plasma and one that can apply to the nonlinear electrostatic study of stiller and interstellar regimes where such types of plasma environment occur.</p> 2022-01-22T00:00:00+00:00 Copyright (c) 2022 Aziz Khan, Abbas Khan, Muhammad Sinan http://mmnsa.org/index.php/mmnsa/article/view/18 Second-grade fluid with Newtonian heating under Caputo fractional derivative: analytical investigations via Laplace transforms 2022-01-17T08:15:15+00:00 Ndolane Sene ndolanesene@yahoo.fr <p>In this paper, we consider the constructive equations of the fractional second-grade fluid. The considered fluid model is described by the Caputo derivative. The problem consists to determine the exact analytical solution using the Laplace transform method. The influence of the order of the used fractional operator has been presented in this paper. We also analyze the influence of the Prandtl number in the dynamics of the temperature distribution according to the variation of the order of the Caputo derivative. The impact of the second-grade parameter and the Grashof number in the dynamics of the velocity has been presented and discussed. The influences of the parameters used in the modeling have been interpreted in terms of a fractional context. In general, it is shown that the order of the fractional operator influences the diffusivity of the considered fluid. This influence can cause an increase or decrease in the temperature and velocity distributions. The main findings of the paper have been illustrated using the graphical representations of the considered distributions according to the order of the fractional operator.</p> 2022-01-26T00:00:00+00:00 Copyright (c) 2022 Ndolane Sene http://mmnsa.org/index.php/mmnsa/article/view/19 Bi-dimensional crime model based on anomalous diffusion with law enforcement effect 2022-01-22T08:08:07+00:00 Francisco Javier Martínez-Farías francisco_martinez@uaeh.edu.mx Anahí Alvarado-Sánchez anahi_a.s@ciencias.unam.mx Eduardo Rangel-Cortes eduardo_rangel@uaeh.edu.mx Arturo Hernández-Hernández arturo_hernandez@uaeh.edu.mx <p>Several models based on discrete and continuous fields have been proposed to comprehend residential criminal dynamics. This study introduces a two-dimensional model to describe residential burglaries diffusion, employing Lèvy flights dynamics. A continuous model is presented, introducing bidimensional fractional operator diffusion and its differences with the 1-dimensional case. Our results show, graphically, the hotspot's existence solution in a 2-dimensional attractiveness field, even fractional derivative order is modified. We also provide qualitative evidence that steady-state approximation in one dimension by series expansion is insufficient to capture similar original system behavior. At least for the case where series coefficients have a linear relationship with derivative order. Our results show, graphically, the hotspot's existence solution in a 2-dimensional attractiveness field, even if fractional derivative order is modified. Two dynamic regimes emerge in maximum and total attractiveness magnitude as a result of fractional derivative changes, these regimes can be understood as considerations about different urban environments. Finally, we add a Law enforcement component, embodying the "Cops on dots" strategy; in the Laplacian diffusion dynamic, global attractiveness levels are significantly reduced by Cops on dots policy but lose efficacy in Lèvy flight-based diffusion regimen. The four-step Preditor-Corrector method is used for numerical integration, and the fractional operator is approximated, getting the advantage of the spectral methods to approximate spatial derivatives in two dimensions.</p> 2022-01-27T00:00:00+00:00 Copyright (c) 2022 Francisco Javier Martínez-Farías, Anahí Alvarado-Sánchez, Eduardo Rangel-Cortes, Arturo Hernández-Hernández http://mmnsa.org/index.php/mmnsa/article/view/14 Three-dimensional fractional system with the stability condition and chaos control 2022-04-05T08:18:11+00:00 Molood Gholami moloodgholami1370@gmail.com Reza Khoshsiar Ghaziani khoshsiar@sci.sku.ac.ir Zohreh Eskandari z.eskandari@sku.ac.ir <p>A three-dimensional system is introduced in this paper and its local stability is analyzed.

The proposed methodology relies on determining an analytical formulation of the shock absorber system’s equation of motion, modelling this formulation on the model-based environment (Matlab/Simulink), and integrating with an accurate aircraft nonlinear dynamic model to observe the performance of landing gear in different touchdown or impact velocities. A suitable landing performance depends on different parameters which are related to the shock absorber system’s working principle. There are three subsystems of the main system which are hydraulic, pneumatic, and tire systems. Subsystems create a different sort of forces and behaviors. The air in the pneumatic system is compressed by the impact effect so it behaves like a spring and creates pneumatic or air spring force so the most effective parameter in this structure is determined as initial air volume. Hydraulic oil in the receptacle of the hydraulic system flow in an orifice hole when impact occurs so it behaves as a damper and creates damping or hydraulic force. The same working principle is acceptable for the air in the tire. The relationship between tire and ground creates a friction force based on dynamic friction coefficient depending on aircraft dynamics. As a result of this study effect of the impact velocity and initial air volume parameters on the system are examined and determined by optimization according to maximum initial load limits of aircraft and displacement of strut and tire surface.</p> 2022-03-31T00:00:00+00:00 Copyright (c) 2022 Nafi Kulaksiz, Sevval Cip, Zeynep Gedikoglu, Muhsin Hancer
