The interaction between two atoms in states with nonzero electronic orbital angular momenta is anisotropic and can be represented by a spherical tensor expansion. The authors derive expressions for the first order (electrostatic) and second order (dispersion and induction) anisotropic interaction coefficients in terms of the multipole moments and dynamic polarizabilities of the atoms and show t...

This paper proposes and evaluates a new spectral smoothing technique whose performance is comparable with LSP interpolation in terms of Euclidean spectral distance measurements but whose interpolated formant trajectories are more reasonable from a phonetic point of view. The approach firstly estimates derivative logarithmic magnitude spectra from both the source and the target frame represented...

In this paper, improved Linear Predictive Coding (LPC) coefficients of the frame are employed in the feature extraction method. In the proposed speech recognition system, the static LPC coefficients + dynamic LPC coefficients of the frame were employed as a basic feature. The framework of Linear Discriminant Analysis (LDA) is used to derive an efficient and reduced-dimension speech parametric s...

OBJECTIVE To examine the relationship and differences between static and dynamic postural stability in healthy, physically active adults. DESIGN Descriptive laboratory study. SETTING Research laboratory. PARTICIPANTS Ten females (age: 21.6 ± 1.2 yrs, mass: 60.8 ± 7.6 kg, height: 165.0 ± 5.0 cm) and ten males (age: 25.1 ± 3.0 yrs, mass: 73.9 ± 8.7 kg, height: 173.5 ± 9.0 cm). MAIN OUTCOM...

The dynamic IO model DIMITRI will be used for explorations of long-term scenarios on technology and demand. The model describes at a sectoral level the relationships between consumption, production and emissions. Technology per sector is described by the inputs from other sectors (represented by IO coefficients) and capital, labour and emission coefficients. Since these coefficients are not sta...

The sharp bounds for the third and fourth coefficients of Ma-Minda starlike functions having fixed second coefficient are determined. These results are proved by using certain constraint coefficient problem for functions with positive real part whose coefficients are real and the first coefficient is kept fixed. Analogous results are obtained for a general class of close-to-convex functions

Three simple speaker verification techniques based on vector quantization, sphericity models and dynamic time warping, respectively, are developed and tested using the same experimental protocol. Two types of feature vectors, the linear prediction derived cepstral coefficients and the melfrequency cepstral coefficients are considered. The efficiency of the combination of the type of acoustic an...
