A New Method for Calculating Propagation Modes of a One Dimensional Photonic Crystal (RESEARCH NOTE)
Photonic band-gap (PBG) crystals offer new dimensions of freedom in controlling propagation of electromagnetic waves. The existence of stop-bands in the transmission characteristic of these crystals makes them a suitable element for the realization of many useful microwave and optical subsystems. In this paper, we calculate the propagation constant of a one-dimensional (1-D) photonic crystal by...
متن کاملA New Method for Calculating Music Similarity
We introduce a new technique for calculating the perceived similarity of two songs based on their spectral content. Our method uses a set of hidden Markov Models to model the temporal evolution of a song. We then compute a dissimilarity distance measure based on finding log likelihood probabilities using Monte Carlo sampling. This method is compared to a previously established technique that pe...
متن کاملA new method for calculating earthquake characteristics and nonlinear spectra using wavelet theory
In the present study using the wavelet theory (WT) and later the nonlinear spectrum response of the acceleration (NSRA) resulted in estimating a strong earthquake record for the structure to a degree of freedom. WT was used in order to estimate the acceleration of earthquake mapping with equal sampling method (WTESM). Therefore, at first, the acceleration recorded in an earthquake using WTESM w...
متن کاملA Method for Calculating the Marginal Rate in the FDH Model
Trade-off reviews the rate of marginal substitution of inputs and outputs onto the efficient frontier. On the other hand, marginal rates of substitution (MRS) are important quantities for analysts and managers. In this paper, by changing the method of Asmild (2004), an algorithm is found that it can be used to calculate the marginal rate of the free disposal hull (FDH) model.
