This paper investigates exponential stability of fractional-order impulsive control systems (FICSs) and synchronization Cohen-Grossberg neural networks (FCGNNs). First, under the framework generalized Caputo derivative, some new results for calculus are established by mainly using L'Hospital's rule Laplace transform. Besides, FICSs translated into differential equations with via utilizing definition Dirac function, which reveals that effect on fractional is dependent order addressed systems....
In this paper, the problem of finite-time synchronization is addressed for a kind fractional-order memristive neural networks (FMNNs). First, new power law inequality with and two fractional differential inequalities are established by means L'Hospital rule, Laplace transform, reduction to absurdity, which greatly extend some existing results. addition, unlike traditional maximum absolute value-based method propose synaptic weights, introducing transformations, FMNNs translated type systems...
Ultrasonic receiving wave can reflect physical properties and damage degree of coal samples. Therefore, it is great significance to deeply study the parameters ultrasonic. In this paper, time-domain characteristics are analyzed systematically, which present good correlation with stress. The frequency spectrum obtained using Fast Fourier Transform (FFT), peak centroid calculated. During entire loading process, fluctuates around 110[Formula: see text]kHz, but corresponding decreases obviously...
Abstract In this paper, a novel rumor-spreading model is proposed under bilingual environment and heterogenous networks, which considers that exposures may be converted to spreaders or stiflers at set rate. Firstly, the nonnegativity boundedness of solution for are proved by reductio ad absurdum. Secondly, both basic reproduction number stability rumor-free equilibrium systematically discussed. Whereafter, global rumor-prevailing explored utilizing Lyapunov method LaSalle’s invariance...
Superelastic carbon microcoils (SCMCs) with high elasticity and coiling chirality were prepared by the Ni-catalyzed pyrolysis of acetylene, novel tactile microsensor elements using SCMCs as sensor material prepared. The a very small size 80×80×80μm3 showed sensitivity 0.3mgf (1Pa). It was found that SCMC arraying in matrix placement method on electrodes dramatically affected sensing properties.
The electrical properties of carbon microcoils (CMCs)/ silicone-rubber composites were studied on the changes in values parameters (impedance, phase angle, resistance, and capacitance) as a function CMC content matrix, using an impedance analyzer frequency range from 40to200kHz. Percolation paths observed at 3wt% matrix. separated percolation threshold. capacitance with small value was dominant less than 3wt%, resistance higher 3wt%.
Coal dust is one of the most serious issues in coal mines. The miners at an excavation face have a high potential for exposure to concentrations dust. main method removing by ventilation. To better control face, it important understand movement patterns and distribution characteristics. This paper used computational fluid dynamics (CFD) approach simulate under two different ventilation systems. Eulerian-Lagrange was study gas‒solid two-phase behavior. concentration distributions systems are...
