acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

For a connected graph G , the distance matrix is real-symmetric where ( u v )-entry between vertex and in . The spectral radius of largest eigenvalue A series-reduced tree with at least one internal all vertices having degree three. Those trees that maximize are determined over fixed order maximum number leaves, respectively.

Growth of bis (thiourea) cadmium formate single crystals from aqueous solution by slow evaporation technique has been reported. To optimize the growth conditions, nucleation parameters such as metastable zone width and induction period values are determined. The grown crystals are characterized by powder XRD technique. Thermal studies by TGA and DTA techniques confirm the decomposition of the s...
