Improved estimation of structure predictor quality

An improved GMM-based voice quality predictor

A voice quality prediction method based on Gaussian mixture models (GMMs) is improved by constructing a feature selection algorithm to provide the best GMMbased prediction quality. The proposed sequential selection algorithm performs N -survivor search, allowing for trading between design complexity and performance. Simulation shows that predictors designed using the proposed algorithm outperfo...

Stochastic Modelling of GPS Phase Observations for Improved Quality Estimation

Data quality information has been recognised as essential in assessing the fitness for use of any spatial dataset, and fundamental to enabling efficient and effective data integration through spatial data infrastructure (SDI). Missing or inaccurate data quality information can result in inappropriate use of the data with associated consequences of poor decision making, reduced utility and decre...

Improved structure-based automatic estimation of pronunciation proficiency

Automatic estimation of pronunciation proficiency has its specific difficulty. Adequacy in controlling the vocal organs is often estimated from spectral envelopes of input utterances but the envelope patterns are also affected by alternating speakers. To develop a good and stable method for automatic estimation, the envelope changes caused by linguistic factors and those by extra-linguistic fac...

Numerical Solution of Hybrid Fuzzy Dierential Equation (IVP) by Improved Predictor-Corrector Method

Production of Fe-C Powders with Improved Structure

Production of Fe-C alloy powders by mechanical alloying was studied. Fe and graphite elemental powder mixtures containing 0.8 and 1.5wt.% graphite were mechanically alloyed using a planetary ball mill. The structural changes of powder particles during mechanical alloying were studied by x-ray diffractometery, scanning electron microscopy and microhardness measurements. For both compositions, me...
