This paper presents a method for speech synthesis by using the generalized harmonic model(GHM) analysis. The aim of this technique to improve the accuracy of analysis parameters is derived from a looping frame harmonic technique. The estimates of harmonic amplitudes and phases are formulated as the peaks of the spectrum amplitude and phase witch located in the pitch frequency multiples exactly....

This paper extends the generalized Hamiltonian method (GHM) (Zhang et al., 2009; Zhang and Wong, 2010) and its half-size variant (HGHM) (Zhang and Wong, 2010) to their -parameter counterparts (called S-GHM and S-HGHM, respectively), for testing the passivity of -parameter descriptor-form models widely used in high-speed circuit and electromagnetic simulations. The proposed methods are capable o...

Dams and water diversions can dramatically alter the hydraulic habitats of stream ecosystems. Predicting how water depth and velocity respond to flow alteration is possible using hydraulic models, such as Physical Habitat Simulation (PHABSIM); however, such models are expensive to implement and typically describe only a short length of stream (10m). If science is to keep pace with development, ...

Studies of intra-species cardiac fiber variability tend to focus on first-order measures such as local fiber orientation. Recent work has shown that myofibers bundle locally into a particular type of minimal surface, the generalized helicoid model (GHM), which is described by three biologically meaningful curvature parameters. In order to allow intra-species comparisons, a typical strategy is t...

This paper extends the generalized Hamiltonian method (GHM) [1], [2] and its half-size variant (HGHM) [2] to their S-parameter counterparts (called S-GHM and S-HGHM, respectively), for testing the passivity of S-parameter descriptorform models widely used in high-speed circuit and electromagnetic simulations. The proposed methods are capable of accurately detecting the possible nonpassive regio...

Abstract. We study two-parameter bifurcation diagrams of the generalized Hénon map (GHM), that is known to describe dynamics of iterated maps near homoclinic and heteroclinic tangencies. We prove the nondegeneracy of codim 2 bifurcations of fixed points of GHM analytically and compute its various global and local bifurcation curves numerically. Special attention is given to the interpretation o...

Bayesian phylogenetic methods are generating noticeable enthusiasm in the field of molecular systematics. Many phylogenetic models are often at stake and different approaches are used to compare them within a Bayesian framework. The Bayes factor, defined as the ratio of the marginal likelihoods of two competing models, plays a key role in Bayesian model selection. We focus on an alternative est...

We have investigated the electronic structure and thermodynamic properties of supercell of the -Al2O3 by first-principles calculation in framework of density functional theory (DFT) and full potential linearized augmented plane wave (FP-LAPW) with generalized gradient approximation (GGA) and by quasi-harmonic Debye model. Our calculated value for direct band gap of α-Al2O3 is 7.2 eV which i...
