Sidelobe artifacts are a common problem in image reconstruction from finite-extent Fourier data.

We show how a single spatially coupled LDPC code based on a protograph can outperform different LDPC codes in iterative differential decoding with significantly lower error floors.

We report the complete spatio-temporal characterization of ultrashort light pulses using a self-referencing device based on shearing interferometry in the space and frequency domains.

Convection in binary fluid mixtures begins with an oscillatory instability to a state of traveling waves (TW) for negative values of the separation ratio psi.

We investigate experimentally and numerically the properties of single-cycle terahertz pulses propagating through a focus.

A subword unit approach to speaker independent connected digit recognition using Hidden Markov Model (HMM) techniques has been investigated.

We give the results of experiments in which we apply our method for speaker dependent transcription of speech to the speaker independent case.

Speaker independent phonetic transcription of fluent speech is performed using an ergodic continuously variable duration hidden Markov model (CVDHMM) to represent the acoustic, phonetic and phonota

This paper reports the results of our experiments on speaker independent phonetic transcription of fluent speech.

In this talk, we examine the issue of acoustic modeling of the fundamental units for recognition.
