Permanent magnet synchronous machines with non-overlapping concentrated fractional-slot windings present certain improved electrical characteristics compared to full pitch windings configurations. This paper describes the design process and construction of two 10-pole permanent magnet synchronous motors, featuring full-pitch and fractional-pitch windings. The paper compares these two configurations in terms of performance and efficiency. Both motors have been designed for direct-drive applications with low speed and high efficiency capability and are intended to be used as a traction drive in an electric prototype vehicle. The proposed motors have external rotor configuration with surface mounted NdFeB magnets. The electromagnetic characteristics and performance are computed and analyzed by means of finite elements analysis. These results are finally compared with the experimental measurements on respective prototypes.

In the development of technology the pitch of shifting know a technique that is used to turn the human voice in the timbre and pitch. This study using methods pitch shifting psola (pitch synchronous overlap add) to change the pitch as well as the timbre sound. The process was about recording a sound so obtained up a noise. Recording signals then processed the results to find the position of the pitch signals on the domain of time. After the position of the pitch known, the distance between the pitch will be multiplied by the number of the scale of a shift that had been determined. The result of the multiplication of the sound is a change in pitch , so producing a higher or lower, Also happens to change the timbre that produces characters a different voice with the original sound. The examination result of pitch and timbre using PSOLA method shows the success as big as 98% for signal sinus examination.Keywords: Pitch, Timbre, Pitch Shifting, PSOLA.

Steady-state vowels are vowels that are uttered with a momentarily fixed vocal tract configuration and with steady vibration of the vocal folds. In this steady-state, the vowel waveform appears as a quasi-periodic string of elementary units called pitch periods. Humans perceive this quasi-periodic regularity as a definite pitch. Likewise, so-called pitch-synchronous methods exploit this regularity by using the duration of the pitch periods as a natural time scale for their analysis. In this work, we present a simple pitch-synchronous method using a Bayesian approach for estimating formants that slightly generalizes the basic approach of modeling the pitch periods as a superposition of decaying sinusoids, one for each vowel formant, by explicitly taking into account the additional low-frequency content in the waveform which arises not from formants but rather from the glottal pulse. We model this low-frequency content in the time domain as a polynomial trend function that is added to the decaying sinusoids. The problem then reduces to a rather familiar one in macroeconomics: estimate the cycles (our decaying sinusoids) independently from the trend (our polynomial trend function); in other words, detrend the waveform of steady-state waveforms. We show how to do this efficiently.

Abstract Parameterization of the speech signal using the algorithms of analysis synchronized with the pitch frequency is discussed. Speech parameterization is performed by the average number of zero transitions function and the signal energy function. Parameterization results are used to segment the speech signal and to isolate the segments with stable spectral characteristics. Segmentation results can be used to generate a digital voice pattern of a person or be applied in the automatic speech recognition. Stages needed for continuous speech segmentation are described.

Voice Conversion Using Pitch Shifting Algorithm by Time Stretching with PSOLA and Re-SamplingVoice changing has many applications in the industry and commercial filed. This paper emphasizes voice conversion using a pitch shifting method which depends on detecting the pitch of the signal (fundamental frequency) using Simplified Inverse Filter Tracking (SIFT) and changing it according to the target pitch period using time stretching with Pitch Synchronous Over Lap Add Algorithm (PSOLA), then resampling the signal in order to have the same play rate. The same study was performed to see the effect of voice conversion when some Arabic speech signal is considered. Treatment of certain Arabic voiced vowels and the conversion between male and female speech has shown some expansion or compression in the resulting speech. Comparison in terms of pitch shifting is presented here. Analysis was performed for a single frame and a full segmentation of speech.

Synchronous gravel water-proof adhesive layer has many advantages, and is widely used to bridge deck pavement. Though the material of synchronous gravel water-proof adhesive layer has high temperature sensitivity, it needs more research that whether this construction can well adapt to seasonal frozen region. Used UTM-100 and self-design testing machine, we tested and analysis the key parameters of the water-proof adhesive layer about SBS nature-changing pitch crushed stones, rubber-asphalt synchronous gravel and high-viscosity asphalt synchronous gravel. Firstly, based on result of core testing under normal temperature, I determined the best mix-proportion for three materials, and tested their shear, tensile strength, deformation performance under different temperature and humidity.

Synchronous belt drives are commonly used in conjunction with an idler on the back face of the belt. However, thickness errors between the belt pitch line and back face of the belt, if present, will result in a change in belt tension on the span, and are considered to affect transmission error. In the present study, the transmission error in a synchronous belt drive with an idler under no load was investigated both theoretically and experimentally using a belt of known thickness error. The computed transmission error agrees well with the experimental data thereby verifying the applicability of the analysis method. In addition, a transmission error was mainly generated by the change in length of the belt pitch line due to the thickness error of the belt. It is shown that the transmission error due to the belt thickness error can be removed by using an automatic tensioner.

Responses of cochlear nucleus units in the chinchilla to iterated rippled noises: analysis of neural autocorrelograms. Temporal encoding of stimulus features related to the pitch of iterated rippled noises was studied for single units in the chinchilla cochlear nucleus. Unlike other periodic complex sounds that produce pitch, iterated rippled noises have neither periodic waveforms nor highly modulated envelopes. Infinitely iterated rippled noise (IIRN) is generated when wideband noise (WBN) is delayed (τ), attenuated, and then added to (+) or subtracted from (−) the undelayed WBN through positive feedback. The pitch of IIRN[+, τ, −1 dB] is at 1/τ, whereas the pitch of IIRN[−, τ, −1 dB] is at 1/2τ. Temporal responses of cochlear nucleus units were measured using neural autocorrelograms. Synchronous responses as shown by peaks in neural autocorrelograms that occur at time lags corresponding to the IIRN τ can be observed for both primarylike and chopper unit types. Comparison of the neural autocorrelograms in response to IIRN[+, τ, −1 dB] and IIRN[−, τ, −1 dB] indicates that the temporal discharge of primarylike units reflects the stimulus waveform fine structure, whereas the temporal discharge patterns of chopper units reflect the stimulus envelope. The pitch of IIRN[±, τ, −1 dB] can be accounted for by the temporal discharge patterns of primarylike units but not by the temporal discharge of chopper units. To quantify the temporal responses, the height of the peak in the neural autocorrelogram at a given time lag was measured as normalized rate. Although it is well documented that chopper units give larger synchronous responses than primarylike units to the fundamental frequency of periodic complex stimuli, the largest normalized rates in response to IIRN[+, τ, −1 dB] were obtained for primarylike units, not chopper units. The results suggest that if temporal encoding is important in pitch processing, then primarylike units are likely to be an important cochlear nucleus subsystem that carries the pitch-related information to higher auditory centers.

Pitch angle control is considered as a practical technique for power regulation above the rated wind speed. As conventional pitch control commonly the proportional–integral controller is used. However, the proportional–integral type may well not have suitable performance if the controlled system contains nonlinearities as the wind turbine system or the desired wind trajectory varied with higher frequency. In the presence of modeling uncertainties, the necessity of methods presenting controllers with appropriate performance as the advanced control strategies is inevitable. The pitch angle based on fuzzy logic is proposed in this work. We are interested to the development of a wind energy conversion system based on permanent magnet synchronous generator. The fuzzy logic controller is effective to compensate the nonlinear characteristics of the pitch angle to the wind speed. The design of the proposed strategy and its comparison with a conventional proportional–integral controller are carried out. The proposed method effectiveness is verified using MATLAB simulation results.
