“…In recent research, investigations of the magnetic, magnetocaloric, and dielectric characteristics of diverse structures have been done via the Monte Carlo technique (MCt), including nano-islands [16], nanowires [17], Borophene Superlattices and core-shell [18,19], graphene-like nanoribbons [20], copper fluorides [21], a nano-graphene bilayer [22], a diluted graphdiyne monolayer with defects [23], a trilayer graphene-like structure [24], a polyhedral chain [25], the Kagome Ferromagnet [26]. Ising models have also been utilized to investigate the mixed systems, like the TbMnO 3 multiferroic system [27], the Gd 2 O 3 nanowire [28], the graphyne [29] and the core-shell Nanotube [30] systems and the Ising thin-film [31]. These models have been useful in predicting magnetic phenomena in a variety of structures, from nanoscale to bulk materials.…”

This research focuses on the electric behavior of a mixed ferrielectric Sunflower-like nanostructure. The structure includes a Core with spin S_i^Z-1 atoms and a Shell with spin σ_j^Z-5/2 atoms. The Blume-Capel model and Monte Carlo technique (MCt) with the Metropolis algorithm are employed. Diagrams are established for absolute zero, investigating stable spin configurations correlated with various physical parameters. The MCt method explores phase transition behavior and electric hysteresis cycles under different physical parameters.

“…Therefore, this paper refers to the method of testing consistency with the cloud model characteristics proposed by Li et al [ 25 ] to calculate the weight boundary of each evaluation index. As a classical random number simulation method, the Monte Carlo Simulation has been extended to the fields of medicine [ 26 ], material science [ 27 ], chemistry [ 28 ] and so on. In order to adapt to the fuzzy attribute of multi-criteria problems, this paper uses the Monte Carlo Simulation Method to select the weight value within the tested weight boundary, so as to obtain a reasonable and fuzzy final weight value.…”

This paper proposes a new debris flow risk assessment method based on the Monte Carlo Simulation and an Improved Cloud Model. The new method tests the consistency of coupling weights according to the characteristics of the Cloud Model firstly, so as to determine the weight boundary of each evaluation index. Considering the uncertain characteristics of weights, the Monte Carlo Simulation is used to converge the weights in a minimal fuzzy interval, then the final weight value of each evaluation index is obtained. Finally, a hierarchical comprehensive cloud is established by the Improving Cloud Model, which is used to input the comprehensive expectation composed of weights to obtain the risk level of debris flow. Through statistical analysis, this paper selects Debris flow scale (X1), Basin area (X2), Drainage density (X3), Basin relative relief (X4), Main channel length (X5), Maximum rainfall (X6) as evaluation indexes. A total of 20 debris flow gullies were selected as study cases (8 debris flow gullies as model test, 12 debris flow gullies in reservoir area as example study). The comparison of the final evaluation results with those of other methods shows that the method proposed in this paper is a more reliable evaluation method for debris flow prevention and control.

In this paper, the thin-film ferroelectric material equation (TFFME) which enables the propagation of solitary polarization in thin-film ferroelectric materials is investigated, and also illustrated through the nonlinear evolution equations. Ferroelectrics are dielectric materials that exhibit nonlinear behaviors in wave propagation. Thin films constructed from the ferroelectric materials are utilized in different modern electronic devices. To investigate the characteristics of new waves, the solitary wave dynamics of the mentioned equation is used in the generalized trial equation scheme. The bright and periodic solutions are obtained by semi-inverse variational principle scheme. Many alternative responses may be obtained through different formulae; each of these solutions offers a distinct graph. The validity of such methods and solutions may be demonstrated by assessing how well the relevant techniques and solutions match up. The effects of free variables on the behavior of few achieved solutions for nonlinear rational exact cases are also plotted and explored depending upon the nature of nonlinearities. The dynamic properties of the obtained results are shown and analyzed by some density, two- and three-dimensional images. The results provide a way for future research on generating optical memories based on the nonlinear solitons.
