We present a detailed comparison of the efficiency and accuracy of the secondand third-order split operator methods, a time dependent modified Cayley method, and the Chebychev polynomial expansion method for solving the time dependent Schrodinger equation in the onedimensional double well potential energy function. We also examine the efficiency and accuracy of the split operator and modified C...

EM training of GMM often suffers from the existence of local maxima and singularities in the likelihood space. In this paper, we present a new Modified Split-and-Merge EM algorithm (MSMEM) for speaker verification tasks, which performs split-and-merge operations to escape from local maxima and reduce the chances of generating singularities. With two modified criteria to select split-and-merge c...

in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...

world population has already exceeded 6.5 billion, out of which about 850 million (13 percent) are undernourished. with the current growth rate, the world community faces even a greater challenge of hunger and food security as the estimated the population will catch 9 billion by the year 2050 with doubled needs for food. at the same time, preservation of biodiversity, stopping deforestation and...
