Visualisation of the vocal tract based on estimation of vocal area functions and formant frequencies
A system for visualisation of the vocal-tract shapes during vowel articulation has been designed and developed. The system generates the vocal tract configuration using a new approach based on extracting both the area functions and the formant frequencies form the acoustic speech signal. Using a linear prediction analysis, the vocal tract area functions and the first three formants are first es...
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
Quantitative and morphologic histochemical studies of the activity of the benz pyrene hydroxylase system in the gastrointestinal tract have been carried out. In nor mal rats activity is found only in the small intestine. In rats in which an increase in activity is induced by oral administration of 1,@-benzanthracene, activity is found throughout the entire gastrointestinal tract but varies in m...
Our previous study showed the presence of γ-amonobutyrate (GABA) system composed of GABA synthesize enzyme glutamate decarboxylase (GAD), GABA and GABA receptors in lower airway tract epithelial cells of GAD67-GFP knock-in mice. The aim of this study was to investigate the presence of GABA system in upper airway tract. To observe GAD expression, mucous membranes of upper airway tract of adult m...
