摘要：
In this article, frequency characteristics, and sensitivity analysis of a size-dependent laminated composite cylindrical nanoshell under bi-directional thermal loading using Nonlocal Strain-stress Gradient Theory (NSGT) are presented. The governing equations of the laminated composite cylindrical nanoshell in thermal environment are developed using Hamilton's principle. The thermodynamic equations of the laminated cylindrical nanoshell are obtained using First-order Shear Deformation Theory (FSDT) and Fourier-expansion based Generalized Differential Quadrature element Method (FGDQM) is implemented to solve these equations and obtain natural frequency and critical temperature of the presented model. The novelty of the current study is to consider the effects of bi-directional temperature loading and sensitivity parameter on the critical temperature and frequency characteristics of the laminated composite nanostructure. Apart from semi-numerical solution, a finite element model was presented using the finite element package to simulate the response of the laminated cylindrical shell. The results created from finite element simulation illustrates a close agreement with the semi-numerical method results. Finally, the influences of temperature difference, ply angle, length scale and nonlocal parameters on the critical temperature, sensitivity, and frequency of the laminated composite nanostructure are investigated, in details.

摘要：
In this paper, a novel direct scheme to solve a set of time-delay fractional optimal control problems is introduced. The method firstly uses a set of Dickson polynomials as basis functions to approximate the states and control variables of the system. Next, the context of these basis functions and the use of a collocation method allow to transform the problem into a system of nonlinear algebraic equations. Finally, the unknown coefficients and control parameters in the original problem can be easily estimated by resolving the new system of equations. Given the high efficiency of the Dickson polynomials to deal with time-delay fractional systems, the proposed strategy involves a very tunable framework for direct trajectory optimization, according to the discretization procedure and the range of arbitrary nodes. The convergence analysis of the proposed method is presented, along with some illustrative examples which demonstrate its most relevant features.

摘要：
The objective of this study is to illustrate the influence of Marangoni convection, nonlinear heat sink/source, thermal radiation, viscous dissipation, activation energy, Soret and Dufour effects on magnetohydrodynamics flow of nanofluid generated by rotating disk. Further, the entropy generation equation is derived as a function of velocity, concentration, and thermal gradients. The governing equations of the model along with associated boundary constraints are reduced to ordinary differential equations by adopting suitable similarity transformation. Later, these equations are tackled numerically by means of shooting technique. The whole examination is performed by using two distinctive nanoparticles of ferrites in particular, manganese zinc ferrite (MnZnFe2O4) and nickel zinc ferrite (NiZnFe2O4) in a carrier liquid (C10H22). The physical characteristics of velocity, thermal, concentration entropy generation, skin friction, and Nusselt number against numerous pertinent parameters are discussed in detail and deliberated graphically. Result reveals that thermal gradient shows substantial enhancement for advanced values of heat sink/source parameter. The entropy production increases with an augmentation in the Brinkman number and Marangoni ratio values. The escalation in Marangoni ratio and Dufour number improves the rate of heat transference.
摘要：
As an emerging urban public transport mode, responsive feeder transit system is flexible and can offer door-to-door services between new districts at margins with low urban transit coverage and trunk bus station. In this study, a joint optimization of running route and scheduling for responsive feeder transit under mixed demand (i.e., reservation and real-time demands) of the time-dependent road network was investigated. A two-stage optimization method was designed together with considering the mixed demands. At the first stage, the initial running route and scheduling were determined according to all reservation demands. At the second stage, the running route and scheduling were continuously optimized based on the real-time demands. The real-time demand responsive strategy, which is built up by using quantitative batch treatment rather than immediate treatment and dynamic route updating strategy for global optimization, were designed by utilizing the submission order of real-time demands. A joint optimization model of running route and scheduling was constructed based on the quantitative batch decision points in the time-dependent road network together with combination of the actual road network. In this model, the minimum total system cost was used, which is composed of the vehicle running costs and passengers' traveling time costs with constraints including vehicle capacity, passengers' time window, and vehicle running time. A solving algorithm based on the adaptive genetic algorithm was designed by considering the characteristics of the joint optimization model.
摘要：
Electrically conductive cementitious composites (ECCC) possesses numerous virtues including low resistivity and high strain sensitivity, which can be applied as a conductive sensor to monitor structural health. This study produced ECCC with three conductive ingredients, consisting of graphite powder (GP), ground granulated blast-furnace slag (GGBS), and steel slag (SS). The uniaxial compressive strength (UCS), flexural strength (FS), and electrical conductivity were investigated, which showed that the GP enhanced the conductivity more remarkably than the other conductive materials. However, it simultaneously reduced the UCS and FS of ECCC. Also, ECCC samples containing SS had higher FS and conductivity than that containing GGBS. To overcome the challenge of excessive variables, this study introduced an artificial-intelligence (AI) based multi-objective optimisation (MOO) model with 252 samples for the FS test and 336 samples for the resistivity experiment. The support vector regression (SVR) was trained with hyperparameters tuned by the beetle antennae search (BAS). The high correlation coefficients (0.981) were achieved on both test sets. The BAS-SVR model acted as the objective function to develop the multi-objective beetle antennae search algorithm (MOBAS-SVR). The Pareto front of a tri-objective mixture optimisation design for ECCC (cost, FS, and resistivity) was successfully obtained as a design reference. Furthermore, sensitivity research was implemented to comprehend the importance of the variables for the FS and electrical resistivity.
摘要：
This theoretical work is devoted to investigating laser-irradiated Floquet topological magnon insulators on a two-dimensional checkerboard ferromagnet and corresponding topological phase transitions. It is shown that the checkerboard Floquet topological magnon insulator is able to be transformed from a topological magnon insulator into another one possessing various Berry curvatures and Chern numbers by changing the light intensity. Especially, we also show that both Tamm-like and topologically protected Floquet magnon edge states can exist when a nontrivial gap opens. In addition, our results display that the sign of the Floquet thermal Hall conductivity is also tunable via varying the light intensity of the laser field. (C) 2021 Elsevier B.V. All rights reserved.

摘要：
In this paper, the effect of La3+ doping on the structure, charge ordering and magnetic properties of Sm0.5Ca0.5MnO3 manganite has been studied. A series of LaxSm0.5-xCa0.5MnO3 (x = 0, 0.25, 0.375, 0.5) samples are prepared by traditional solid state reaction. The crystal structures are studied by X-ray diffraction technology. The results show that they are single-phase and orthorhombic structures. The change of La3+ ion concentration does not change the crystal structure of the samples. The surface morphology and particle size of the samples are studied by scanning electron microscope. The average particle size of the samples is several micrometers. Energy-dispersive spectrometer is used to detect the composition of the samples. The results show that the actual element composition of the samples is consistent with that of the modulated element. Magnetic properties are analyzed by magnetization versus temperature (M-T) curves and magnetic hysteresis (M-H) loops. Below 50 K, the zero-field-cooling (ZFC) and field-cooling (FC) M-T curves diverge obviously, which is a typical feature of spin glass transition. The ZFC and FC M-T curves show a significant protuberance peak between 215 and 274 K, which represents the existence of charge-ordered (CO) anti-ferromagnetic (AFM) state. With increasing La3+ ion doping concentration, the CO temperature gradually decreases. Moreover, the butterfly-type M-H loops also confirm the existence of CO-AFM phase in samples. In a few words, the competition between FM and AFM phases determines the charge ordering behavior and magnetic properties of the samples.

摘要：
Magnetohydrodynamic axisymmetric flow of viscous nanoliquid towards a variable stretching sheet is scrutinized. Flow is generated due to nonlinear stretching. Joule heating, heat flux and dissipation are analyzed in heat expression. Random and thermophoresis diffusions are considered. Physical description of entropy generation is also accounted. Entropy generation and heat transfer analysis are scrutinized through thermodynamics laws. Furthermore chemical reaction along with Arrhenius activation energy is addressed. Ordinary differential system is obtained through suitable variables. Homotopic convergent solutions for nonlinear system is developed. Influence of flow variables on entropy rate, velocity, Bejan number, concentration and temperature are analyzed. Further velocity gradient and heat and mass transfer rates are discussed. Reduction in velocity is noticed for magnetic variable. Thermal field has an enhancing trend for magnetic and Eckert number. Larger thermophoresis variable rises the temperature. An increment in entropy rate is observed for magnetic parameter. An increment in drag force is seen for magnetic variable. (c) 2021 Published by Elsevier Ltd.

摘要：
The study explored the 3D numerical solution of an unsteady Ag-MgO/water hybrid nanofluid flow with mass and energy transmission generated by a wavy rotating disc moving up and down. The nanofluid is generated in the context of Ag-MgO nanomaterials. Magnesium oxide and silver nanoparticles have been heavily reported to have broad-spectrum antibacterial operations among metal oxides and metals. Silver nanoparticles are without a doubt the most commonly used inorganic nanoparticles, with numerous innovations in biomaterial's detection and antimicrobial operations. However, in current paper, the intention of the analysis is to boost thermal energy transmitting rates for a range of industrial implementations. When compared to a flat surface, energy transition is increased up to 15% due to the wavy swirling surface. The problem has been formulated as a system of PDEs, which included the Navier Stokes and Maxwell equations. Following that, the modeled equations are reduced to a dimensionless system of differential equations. The derived equations are then solved numerically using the Parametric Continuation Method (PCM). The findings are displayed graphically and debated. The geometry of a spinning disc is thought to have a positive impact on velocity and heat energy transfer. The insertion of nanostructured materials (silver and magnesium-oxide) increased the carrier fluid's thermal properties considerably. It is more effective at dealing with low energy transmission.
摘要：
This study investigated the passivation of multiple heavy metals (Cd, Cr, Cu, Zn, and Pb) in river sediments by composting with rice straw. The correlation between the selected environmental factors and the distribution of heavy metal fractions was assessed by multivariate analysis. The results suggested that the composting could reduce the bioavailability of Cu, Cd, Cr, and Pb. The influences of composting on the passivation of these five heavy metals are different. The greatest passivation of heavy metals is for Cd, which its bioavailability decreased 17.72%. The bioavailability of Cu, Pb, and Cr also partly decreased. However, there was almost no effect on the bioavailability of Zn. The results of multivariate analysis revealed that the predominant parameters affecting the variation of the bioavailability of different heavy metals were different in a complex composting system with multiple heavy metal pollution. While the variation partitioning analysis indicated that water-soluble carbon (WSC) was the statistically main factor affecting the bioavailability of Cd, Cr, Cu, Zn, and Pb. It provides a theoretical reference for optimizing the co-composting process in remediation of different heavy metal contamination in sediments.
摘要：
In the environment of cloud computing, the data produced by massive users form a data stream and need to be protected by encryption for maintaining confidentiality. Traditional serial encryption algorithms are poor in performance and consume more energy without considering the property of streams. Therefore, we propose a velocity-aware parallel encryption algorithm with low energy consumption (LECPAES) for streams in cloud computing. The algorithm parallelizes Advanced Encryption Standard (AES) based on heterogeneous many-core architecture, adopts a sliding window to stabilize burst flows, senses the velocity of streams using the thresholds of the window computed by frequency ratios, and dynamically scales the frequency of Graphics Processing Units (GPUs) to lower down energy consumption. The experiments for streams at different velocities and the comparisons with other related algorithms show that the algorithm can reduce energy consumption, but only slightly increases retransmission rate and slightly decreases throughput. Therefore, LECPAES is an excellent algorithm for fast and energy-saving stream encryption.

摘要：
MoS2 reinforced PDMS/MC nylon composites had been fabricated by in situ polymerization to further enhance the comprehensive properties of nylon material. Polydimethylsiloxane was pre-sythesized as the activator of the system and MoS2 was compounded as the wear-resisting agent. The thermal stability, mechanical properties, friction and wear properties of composites with different MoS2 contents were tested. The results showed that the crystallization and thermal stability of nylon matrix were increased with the addition of MoS2, while the tensile strength and impact strength were slightly reduced. The composites finally presented excellent friction properties with 3 wt% MoS2, whose friction coefficient was reduced to 0.75 (18.48% decrease) corresponding to the wear rate of 0.4145 x 10(-8) g Nm(-1).

摘要：
To improve the effectiveness of allocating the education environmental resources in college music, an allocation model for education environmental resource based on rough set and data reduction is proposed. First, an allocation model of risk preference for education environmental resource based on rough set and data reduction classifier is developed. This model divides risk preference into the existing risk preference and non-existent risk preference. Also, it trains and optimizes the data set for the allocation of education environmental resources by rough set and data reduction classifier. Second, as the rough set and data reduction classifier may fail sometimes in predicting the allocation of education environmental resource, the fuzzy clustering based on rough set is optimized, and combined with the data reduction theory to enhance the effectiveness of allocating the education environmental resources. Finally, based on the simulation research on the allocation model of education environmental resources, the proposed algorithm can obtain a more reasonable allocation of education environmental resources, which embodies the effectiveness of the algorithm. The data reduction classifier of a rough set is used to train and optimize the data set of the allocation of education environmental resources, and visual c++ is used to realize the allocation of education environmental resources. The simulation results show that the algorithm can effectively allocate education environmental resources. The model takes into account the characteristics of the incompatibility between the evaluation of historical data and the complex index system in the evaluation decision-making. It can divide the evaluation decision-making table reasonably, and realize the objective calculation of the weights of each evaluation index based on the rough set condition through hierarchical calculation.

摘要：
In the present paper, for the first time, we propose a variable-order hyperchaotic system for information security. Firstly, we study the dynamical behaviors of a memristor oscillator through well-known numerical and analytical tools, such as the Lyapunov exponents, stability of equilibria, and bifurcation diagram. Then as an engineering application, a variable-order fractional version of the system is proposed for sound encryption. In comparison with integer and conventional constant fractional-order chaotic memristor oscillator, the proposed variable-order fractional system shows more complex characteristics and more degrees of freedom due to the existence of time-varying fractional derivatives. Thus, the proposed system is an appropriate choice for data transmission and information security. To illustrate the proper performance of the suggested system for encryption purposes, sound encryption is successfully performed, and its excellent results are demonstrated. The predictor-corrector method is utilized for numerical simulation. Then, a new type-2 fuzzy disturbance observer-based robust control is offered for synchronization of the variable-order hyperchaotic system. The stability and convergence of the disturbance estimator and closed-loop system are proven. Lastly, the synchronization results, which confirm the appropriate performance of the proposed method in the presence of the external disturbances, are demonstrated. (c) 2021 Elsevier Ltd.

摘要：
Numerical simulation of hybrid nanomaterial free convection with helps of CVFEM was performed. Dispersing nanomaterial can minimize the exergy loss. The modeling outputs were depicted in terms of 3D plots and contours. Because of reduction of irreversibility with inclusion of nanoparticles, hybrid nanofluid was employed. Increasing Ha results in greater X-d and it is more sensible when convection become stronger. The growth of permeability increases nanomaterial motion and reduces the exergy drop.
