This paper investigates the use of features based on posterior probabilities of subword units such as phonemes. These features are typically transformed when used as inputs for a hidden Markov model with mixture of Gaussians as emission distribution (HMM/G ...
Recently, entropy measures at different stages of recognition have been used in automatic speech recognition (ASR) task. In a recent paper, we proposed that formant positions of a spectrum can be captured by multi-resolution spectral entropy feature. In th ...
In recent papers, entropy computed from sub-bands of the spectrum was used as a feature for automatic speech recognition. In the present paper, we further study the sub-band spectral entropy features which can give the flatness/peakiness of the sub-band sp ...

A new cubic Ta-bronze (1) KTa1+z+(5-delta)O3 [z similar or equal to 0.107 (3)] was obtained on a cathode by molten salt electrolysis of the system K2TaOF5-K3TaO2F4-(KF + NaF + LiF)(cutectic). Black, metallic cubic crystals of (1) are formed together with t ...
The crystal structure of a strontium-imidazolium polymeric material obtained from the reaction of zwitterionic 1,3-bis(carboxymethyl)-imidazolium with SrCO3 (2:1) in water is reported. The compound crystallized in the orthorhombic space group Pcc2 with a = ...
We have determined the crystal structure of YodA, an Escherichia coli protein of unknown function. YodA had been identified under conditions of cadmium stress, and we confirm that it binds metals such as cadmium and zinc. We have also found nickel bound in ...
More than 50 yr. after the proposal of the Dewar-Chatt-Duncanson model for the binding of olefins to transition-metal atoms, the first structurally characterized example of a silver-C2H4 complex [Ag(h2-C2H4)3]+ was obtained with the help of the very weakly ...
Crack-tip behaviour in metals is among the most basic problems in mechanics of materials. Yet, long-standing experimental evidence suggests that crack-tip twinning in face-centred-cubic (f.c.c.) metals is highly dependent on the material, temperature and l ...
This paper introduces an approach to wavelet packet best basis searches using the generalized Renyi entropy. The approach extends work by R.R. Coifman and M.V. Wickerhauser who showed how Shannon entropy can be used as an additive cost function in the wave ...
