Compensatory speech motor patterns occur in response to sensory changes in the vocal tract to facilitate natural sounding speech. The purpose of this project was to investigate speech compensation to midline lingual piercing. In the first experiment, two groups of female speakers (one with tongue piercing) produced two sets of speech samples. Tongue piercing barbells were kept in place as basel...

Speech Segmentation is the measure of the change point detection for partitioning an input speech signal into regions each of which accords to only one speaker. In this paper, we apply two features based on multi-scale product (MP) of the clean speech, namely the spectral centroid of MP, and the zero crossings rate of MP. We focus on multi-scale product analysis as an important tool for segment...

Stress level detection is important for human error prevention and health care services. Speech based stress level detection is the most effective as speech data can be obtained in nonintrusive and inexpensive ways. In this paper, we explore the features that use Double-Layered Subband (DLS) filter for detecting stress level from speech. Spectral Centroid Frequency (SCF) and Spectral Centroid A...

In this paper a further generalization of differential evolution based data classification method is proposed, demonstrated and initially evaluated. The differential evolution classifier is a nearest prototype vector based classifier that applies a global optimization algorithm, differential evolution, for determining the optimal values for all free parameters of the classifier model during the...

Centroid index is the only measure that evaluates cluster level differences between two clustering results. It outputs an integer value of how many clusters are differently allocated. In this paper, we apply this index to other clustering models that do not use centroid as prototype. We apply it to centroid model, Gaussian mixture model, and arbitrary-shape clusters.

Affine isoperimetric inequalities compare functionals, associated with convex (or more general) bodies, whose ratios are invariant under GL(n)-transformations of the bodies. These isoperimetric inequalities are more powerful than their better-known relatives of a Euclidean flavor. To be a bit more specific, this article deals with inequalities for centroid and projection bodies. Centroid bodies...

In the title compound, C(19)H(13)BrO(3)S, the 4-bromo-phenyl ring makes a dihedral angle of 64.11 (2)° with the mean plane [r.m.s. deviation = 0.01 (2) Å] of the naphtho-furan ring. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits slipped π-π inter-actions between the central naphtho-furan benzene rings of neighbouring mol-ecules [...

We propose an anchorless distributed technique for estimating the centroid of a network of agents from noisy relative measurements. The positions of the agents are then obtained relative to the estimated centroid. The usual approach to multi-agent localization assumes instead that one anchor agent exists in the network, and the other agents positions are estimated with respect to the anchor. We...

Mohammed Abdel Ghani Dept. ofEE, S. Illinois University, Carbondale, IL A circuit for fast, compact and low-power focal-plane motion centroid localization is presented. This chip, which uses mixed signal CMOS components to implement photodetection, edge detection, ON-set detection and centroid localization, models the retina and superior colliculus. The centroid localization circuit uses time-w...
