Gaunt coefficients express angular momentum conservation rules. They are therefore required in the combination of atomic orbitals. In this case, the angular factors are real spherical harmonics and the Gaunt coefficients appear when their products are linearized. The Gaunt coefficients may be pre-calculated and stored. This work describes new index functions for storing and retrieving the requi...
In this paper an estimator of speech spectrum for speech enhancement based on Laplacian Mixture Model has been proposed. We present an analytical solution for estimating the complex DFT coefficients with the MMSE estimator when the clean speech DFT coefficients are mixture of Laplacians distributed. The distribution of the DFT coefficients of noise are assumed zero-mean Gaussian.The drived MMSE...
this study is focused on developing an integrated optimization-simulation based genetic algorithm model (iosga) to develop the operational policies for a multi-purpose reservoir system. the objective function of the optimization model is considered to be a linear function of reliability (rel), resiliency (res), and vulnerability (vul) of the river-reservoir system. genetic algorithm (ga) is emp...
This research was conducted in a state university for the purpose of enhancing academic work leadership on the basis of knowledge management and making recommendations to the high-ranking managers of that university. The statistical population consisted of 200 staff and faculty members of the university, who were chosen by the simple random sampling method. Measurement tools were knowledge mana...
Soil erosion leads to washing topsoil, organic matter and soil fertility will decrease eventually. In order to combat erosion and loss of soil, conservation and watershed sediment generation in the NIR region, based on the WSM modeling was performed to estimate the severity of soil deposits. The model with six factors was scored for each work unit. Usually suitable model for certain areas that ...
