In speech recognition, a discriminative quefrency weighting can be achieved by somewhat decorrelating the frequency sequence of log mel-scaled filter-bank energies with a computationally inexpensive filter. In this paper, we show how the spectral parameters that result from this kind of frequency filtering, both alone and combined with filtering of their time trajectories, are competitive with ...

Binding isotherms have been determined for the association of horse heart cytochrome c with dioleoyl phosphatidylglycerol (DOPG)/dioleoyl phosphatidylcholine (DOPC) bilayer membranes over a range of lipid compositions and ionic strengths. In the absence of protein, the DOPG and DOPC lipids mix nearly ideally. The binding isotherms have been analyzed using double layer theory to account for the ...

This work is devoted to analyzing adaptive filtering algorithms with the use of sign-regressor for randomly time-varying parameters (a discrete-time Markov chain). In accordance with different adaption and transition rates, we analyze the corresponding asymptotic properties of the algorithms. When the adaptation rate is in line with the transition rate, we obtain a limit of a Markov switched di...

We prove the propagation of regularity, uniformly in time, for the scaled solutions of the one-dimensional dissipative Maxwell models introduced in [3]. This result together with the weak convergence towards the stationary state proven in [24] implies the strong convergence in Sobolev norms and in the L norm towards it depending on the regularity of the initial data. As a consequence, the origi...

In attempting to develop large-scaled metabolic models using general dynamic modeling methods, a large set of data, such as kinetics mechanisms and parameters, is required. It is difficult to obtain a complete set of rate equations and kinetic parameters. To solve the problem, we have proposed an algorithm which simulates a pathway model including dynamic kinetic parts and flux-based static par...

Most of the research in Voice Conversion (VC) is devoted to spectral transformation while the conversion of prosodic features is essentially obtained through a simple linear transformation of pitch. These separate transformations lead to an unsatisfactory speech conversion quality, especially when the speaking styles of the source and target speakers are different. In this paper, we propose a m...

Designs for 0tting a generalized linear model depend on the unknown parameters of the model. The use of any design optimality criterion would therefore require some prior knowledge of the parameters. In this article, a graphical technique is proposed for comparing and evaluating designs for a logistic regression model. Quantiles of the scaled mean-squared error of prediction are obtained on con...

The effects of synthesized voice warning parameters on perceived urgency were examined in order to build a detailed and usable description of the relation between the parameters of synthesized voice warnings and perceived urgency. Ten native and 10 non-native English speakers participated in 4 experiments to evaluate and quantify the effects of the voice parameters. The results showed that spee...
