Finite difference time domain (FDTD) method is a robust and accurate algorithm which is widely used in computational electromagnetic field and the simulation of optical phenomenon. In this paper, parallel FDTD based on overlapped domain decomposition is used to simulate the band gap of photonic crystals and the quantum efficiency of thin film solar cells. The light-trapping effect is also analyzed...
In this note,Kalman filtering for systems with multiple packet dropouts is introduced. The random multiple packet dropouts are assumed to subject to the Bernoulli random binary distribution. A Kalman filter based on the white, zero-mean, correlated noises is proposed to design. And the stability of the designed filter is analyzed in this paper. Finally, a numerical example is exploited to show the...
This paper presents a general uncertain complex singular dynamical network model. Since the nodes of the network are singular systems, the overall network can only be described by a singular model. Due to the flexible of singular systems in describing practical applications, the complex singular dynamical network has more applications than the regular complex network in which the nodes are described...
This paper simulates human visual perception with regard to visual adaptation under the change of illumination. To reflect visual adaptation in scene rendering, we adopt the mathematic models simulating photopic, scotopic, and mesopic vision. We also take consideration the characteristic that adaptation to low visibility takes longer than high visibility. As a result, the outcome of the animation...
The iterative methods such as BiCGStab for solving electromagnetic field integer equations have a complexity of O(N2), which can be reduced to O(N logN) by multilevel fast multipole method (MLFMM). For large scale problems, MLFMM should be parallelized, and the iterative convergence can be accelerated by preconditioners such as incomplete inverse triangular factorization preconditioner. The interpolation...
