This article evaluates two ways of characterization of EEG signals for classification of activity and linguistic inactivity, essential preprocess for the development of brain-computer interfaces (BCI) based on imagined speech. The first characterization used the calculation of the teager energy based on the discrete wavelet transform (DWT). The second characterization was based on the calculati...

identifying an unknown language from the test utterances. In this paper, a new method of feature extraction, viz., Teager Energy Based Mel Frequency Cepstral Coefficients (T-MFCC) is developed for identification of perceptually similar languages. Finally, an LID system is presented for Hindi and Urdu (perceptually similar Indian languages) to demonstrate effectiveness of newly proposed feature ...

Aiming at the difficulty of fault location multi-source transmission lines, this paper proposes a method for multi-terminal lines based on branch judgment matrix. The traveling wave signal is decomposed by Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN), and IMFs sensitive components that can characterize characteristics target signals are selected constructing corr...

In this paper, we propose a novel discriminative speech frame selection (DSFS) scheme for the problem of in-set/out-of-set speaker identification, which seeks to decrease the similarity between speaker models and background model (or antispeaker model), and increase the accuracy of speaker identification. The working scheme of DSFS consists of two steps: speech frame analysis and discriminative...

Teager Energy and Energy-Entropy Features are two approaches, which have recently been used for locating the endpoints of an utterance. However, each of them has some drawbacks for speech in noisy environments. This paper proposes a novel method to combine these two approaches to locate endpoint intervals and yet make a final decision based on energy, which requires far less time than the featu...

This article proposes a fast and robust technique for instantaneous phase angle estimation of three-phase voltage systems under unbalanced distorted conditions. It mainly relies on the Clarke transformation, Teager energy operator, delayed signal cancellation (DSC) approach. Unlike an adaptive DSC-based synchronous-reference frame phase-locked loop (PLL), proposed avoids interdependent loops, t...
