Localized surface plasmon resonances (LSPR) give rise to enhanced fields near the interface between the metallic and dielectric boundary. Strong excitation intensities can lead to the formation of photothermal bubbles around plasmonic nanoparticles. Numerical simulation is indispensable in predicting and analyzing plasmonic bubble as the measurement is always too expensive or too complicated to be...
The objective of this paper is to extend the relaxed conditions on the existence of the backstepping controllers and observers obtained in a recent literature to the case of parabolic Partial Differential Equations (PDEs) with the same diffusion. Moreover, an observer-based output feedback controller is designed for the considered systems with the new conditions. Then, the corresponding exponential...
In time difference of arrival (TDOA) location system, the cooperative localization algorithm based on Particle swarm optimization (PSO) and Taylor series not only solves the problem that particle swarm is easy to fall into local optimum, but also avoids the inappropriate initial value which leads to non convergence of Newton iterative algorithm. In practical applications, the coordinate information...
In geosynchronous (GEO) synthetic aperture radar (SAR), the high orbit height and the long integration time would lead to the significant round-trip delay time and the curved flight path, thus the traditional range model with ‘stop-go’ assumption will be ineffective. In this Paper, based on the analysis of instantaneous Doppler frequency of GEO SAR, an equivalent midpoint mathematical model is proposed...
In this paper, a numerical scheme is presented to accurately model thermoplasmonics for arbitrarily shaped nanostructures. The volume integral equation (VIE) is utilized to calculate the light absorption, then the temperature profile is obtained by the moment of method (MoM) solution of the steady-state thermal equation. The accuracy and capability of proposed scheme are demonstrated by numerical...
In this paper, we propose a sequential approach for emergency logistics planning in natural disasters. We establish a dynamic time-dependent nonlinear model, which describes a setting in which commodities are transported from dispatching centers to affected areas with different transportation modes in each emergency response period. Then, we develop a matrix-coding-based genetic algorithm to solve...
According to the basic principle of AM modulation and the DDS technology, realizes the AM modulation signal generator design and the simulation by using Matlab/DSP Builder and the QuartusII software. Using graphic design of simulink established model of AM modulation module, substitutes for the VHDL programming, and obtains the system-level simulation; Completes the VHDL file conversion through DSP...
In this paper, a kind of shape memory alloy (SMA) model based on hysteretic nonlinear theory and data mining was developed and applied in vibration control on rotor system with SMA bearing. Nonlinear difference item was introduced to interpret the hysteretic phenomenon of SMA. Arctangent function was introduced to describe the variation of SMA stiffness with temperature. Based on above, all of possible...
