Neural network-Based tonal feature for vietnamese speech recognition using multi space distribution model - Nguyen Van HuyDISCUSSION AND CONCLUSION For the purpose of how to adapt BNF which is used for extracting tone feature, to MSDHMM for Vietnamese ASR, we presented a process of extracting tonal feature based on a bottle neck MLP network that so called tonal bottle neck feature (TBNF) which included both voiced/unvoiced decision. In Table 1, based on careful...

Extended iso geometry analysis of crack propagationWe have applied the XIGA to solve the crack propagation problems. Several numerical examples are considered. The obtained results in stress intensity factor and crack path are investigated and compared with other numerical methods such as XFEM and scale boundary finite element method. Very good agreements on the solutions are found. It is sh...

Application of fluorescence technique in studying dental cariesIn this study, we have investigated the fluorescence of sound teeth, teeth with dental calculus, cavitated caries and hidden caries. The sound teeth emitted the blue-green fluorescence on a white background with broad emission spectra from 410 nm to 650 nm (with three peaks at 450 nm, 500 nm and 520 nm), while the samples with different type...

Two-Phase short-circuit fault detections for transmission line using wavelet transform and neural network - Truong Tuan AnhCONCLUSION AND FURTHER DEVELOPMENT The paper has proposed a new approach to detect and locate the two-phase short-circuit fault on the three-phase transmission lines. The proposed method uses the Daubechies wavelet decompositions of the phase currents signals from the beginning of the transmission line only. For the selected configuration o...

Application of a Dung’s Model to Predict Ductile Fracture of Aluminum Alloy Sheets Subjected to Deep DrawingThe subroutine is verified via the simple finite element models of plane strain and hydrostatic tension. The analysis results based on Dung’s model have been compared to the GTN model in Abaqus and the results from literature. It is shown that the Dung’s model is capacable of predicting damage localization of metallic material. The two deep...

A consecutive-Interpolation finite element method for heat transfer analysisWe have successfully extended the consecutive-interpolation finite element method (CFEM) to solve the heat transfer problem in 2D. The CFEM provides some advantages as follows: Smooth temperature gradient without using any smoothing technique, while retaining increasing the number of degrees of freedom. Higher accuracy due to the higher-orde...

Extended Radial Point Interpolation Method for crack analysis in orthotropic mediaA meshless extended radial point interpolation method (XRPIM) has been proposed for cracks analysis in orthotropic median under different loadings and several material orientations. This method is convenient in treating the Dirichlet boundary conditions because of the RPIM shape functions satisfying the Kronecker’s delta property. Several nu...
