In this paper, we address a sparse signal reconstruction problem of nonlinear dynamic system in Wireless sensor networks (WSNs). A distributed reconstruction algorithm of sparse nonlinear signal is proposed based on sigma-point filter and consensus filter with embedded pseudo-measurement (PM) technology. For numerical accuracy, its square-root version is further developed. By embedding the PM equation,...
The virial equation of state (VEOS) is a density expansion of the thermodynamic pressure with respect to an ideal-gas reference. Its coefficients can be computed from a molecular model, and become more expensive to calculate at higher order. In this paper, we use GPU to calculate the 8th, 9th and 10th virial coefficients of the Lennard-Jones (LJ) potential model by the Mayer Sampling Monte Carlo (MSMC)...
In this paper, we propose a T-S fuzzy model based controller for the H-type gantry stage. The synchronized error, which is caused by mismatch quality and friction, is an important control problem for the H-type gantry stage. Utilizing a Lagrangian equation, all states can be formulated as a state equation. Furthermore, the T-S fuzzy model based controller is designed to reduce velocity error, and...
On the basis of linear theory of three-dimensional piezoelasticity, the propagation of elastic waves in piezoelectric cylindrical waveguides with sectorial cross-section is analyzed. Dispersion relations in analytical forms are obtained for various boundary conditions. Numerical results including real, imaginary and complex branches of full dispersion spectra are presented to show the essential characteristics...
The nonlinear kinetic Lorenz equation for describing atmospheric turbulence is also regarded as the basic kinetic model in oceanic kinetics. In this paper, the bifurcation diagram, phase diagram, time-distance diagram and power spectrum diagram according to the classical Lorenz system are simulated; the kinetic characteristics of the system are analyzed; the parameter values leading to chaos are given;...
This paper indicates the chaotic essence of Duffing system and qualitatively selects the range of the amplitude parameter and the frequency parameter when system is in the state of chaos, which can effectively control the system to the desired state of chaos by making the global bifurcation diagram, phase diagram and poincare sections and analyzing its movement behavior with periodic excitation force...
The static and dynamic problems of an imperfectly bonded, orthotropic, piezoelectric laminate in cylindrical bending are investigated based on the equations of piezoelasticity. A general spring layer is adopted to model the bonding imperfections at the interfaces of the laminate. The formulations of reverberation-ray analysis are developed. The approach is verified by comparing the results with those...
The focus of this paper is to study an infinite composite hollow cylinder consisting of a homogeneous piezoelectric layer and a functionally graded elastic layer. A general linear spring-layer model is employed to characterize the interface between the two layers, which may be perfect or imperfect. Directly based on the three-dimensional exact equations of elasticity and piezoelasticity, the state...
