Speech coding forms a crucial element in speech communications. An important area concerning it lies in feature extraction which can be used for analyzing Hindustani Classical Music. An important feature in this respect is the fundamental frequency often referred to as the pitch. In this work, the terms pitch and its acoustical sensation, the frequency is used interchangeably. There exists nume...

The identity of a melody resides in its sequence of pitches and durations, both of which exhibit surface details as well as structural properties. In this study, pitch contour (pattern of ups and downs) served as pitch surface information, and tonality (musical key) as pitch structure; in the temporal dimension, surface information was the ordinal duration ratios of adjacent notes (rhythm), and...

Nanowire structures arranged in a hexagonal lattice are to be characterized terms of their diameter, height and pitch. A scatterometer an imaging Mueller matrix ellipsometer, which is combination commercial ellipsometer microscope, have been used as measurement tools. These measurements supported by numerical simulations using the finite element method characterize structure parameters.

A dynamic computer model of a turbine was developed in MATLAB in order to study the behavior of vertical axis wind turbines (VAWTs) with variable pitch (articulating) foils. The simulation results corroborated the findings of several empirical studies on VAWTs. The model was used to analyze theories of pitch articulation and to inform the discussion on turbine design. Simulations of various mod...

Hydraulic pipeline transportation of a piped vehicle is new mode with energy-saving potential and environmental protection. In order to analyze the turbulent characteristics flow around vehicle, large eddy simulation (LES) method was adopted simulate hydraulic vortex at Reynolds number Re = 140,467 diameter-to-length ratios 0.4, 0.5, 0.6, 0.7. The results showed that main factor affected gap ve...

Objective(s): This study was carried out to boost the pharmacologic influence of carvedilol (CAR) (as a poorly water-soluble drug) by developing CAR-eudragit® RS100 (Eud) nanofibers and nanobeads benefiting an electrospraying approach. Materials and Methods: CAR-Eud nanoformulations with varying ratios (1:5 and 1:10) at total solution co...

dynamic behavior of ground supported cylindrical storage tanks (cst) is of crucial importance because of its applications in industrial complexes. seismic behavior of tanks is greatly affected by the height to diameter ratio, fluid height and fluid type. five csts with different height to diameter ratios, three csts with the same height and diameters but various fluid heights and one cst with t...

Subjects judged "ratios" and "differences" in pitch between pairs of tones that varied in frequency. Half of the subjects listened to stimuli that ranged from 191 tb 844 Hz; the other half received a range that varied from 191 to 3740 Hz. For both ranges, the rank orders ofjudgrnents in the two tasks were essentially the same. If subjects actually use ratio and difference operations on the same...
