Polyimide (PI) aerogels, renowned for their nano-porous structure and exceptional performance across a spectrum of applications, often encounter significant challenges during fabrication, primarily due to severe shrinkage. In this study, we innovatively incorporated ceramic fibers varying diameters into the PI aerogel matrix enhance shape stability against The resulting fiber-reinforced (CF-PI) composites as well in thermal decomposition, insulation, compression resistance were...
By introducing a sine function, non-autonomous multi-wing chaotic system is proposed. The has an infinite number of equilibrium points and produces symmetrical attractors. complex dynamical behaviors the are demonstrated by phase portraits, Lyapunov exponents spectrum bifurcation diagram. effect driving amplitudes initial conditions on resulting dynamics then thoroughly investigated. attractors will enter different oscillatory states or have topological changes. rotational coexisting depend...
An autonomous memristive circuit is implemented by an active third-order generalized memristor. The mathematical model established and the stability of equilibrium point divergence are analyzed. Lyapunov exponents bifurcation analysis demonstrate complex dynamical behaviors system. As internal parameter voltage controlled memristor changed, system changes from bursting chaos to general chaos, which includes chaotic attractor periodic attractor. This produces similar clusters discharge...
This paper introduces a charge-controlled memristor based on the classical Chuas circuit. It also designs novel four-dimensional chaotic system and investigates its complex dynamics, including phase portrait, Lyapunov exponent spectrum, bifurcation diagram, equilibrium point, dissipation stability. The appears as single-wing, double-wings attractors spectrum of is symmetric with respect to initial value. In addition, asymmetric coexisting are generated by changing value parameters. findings...
The structure of an aerogel is vital to its thermal conductivity. In this study, improved cubic model, i.e., face-filled intersecting square rods (F-ISR) proposed better approximate the microporous PI aerogels with severe fiber conglutination or even polymer flakes, further predict their effective equations for prediction are derived theoretically. By assigning average pore diameter (4V/A) side length model cube, and at same time coupling porosity specific surface area measured from mercury...
A four-dimensional chaotic system with complex dynamical properties is constructed. The complexity of the was evaluated by equilibrium point, Lyapunov exponential spectrum and bifurcation model. coexistence model proves attractors. [Formula: see text] SE algorithms are used to compare analyze corresponding characteristics system, most integer-order obtained. In addition, circuit switch between different attractors novel. particular, more parameters selected for fractional-order through...
We construct a three-dimensional chaotic system based on TANG and analyze the dynamics equilibrium points, phase diagram, Lyapunov exponential spectrum, bifurcation complexity. The more complexly dynamic behaviors indicate that our designed has different topology, anti-monotonic property attractor coexistence phenomenon from system. of point can select initial value is suitable for secure communication by analyzing attractor. actual digital circuit implemented with field programmable gate...
