In this paper we present a method based on a time-varying sinusoidal model for a robust and accurate estimation of amplitude and frequency modulations (AM-FM) in speech. The suggested approach has two main steps. First, speech is modeled as a sinusoidal model with time-varying amplitudes. Specifically, the model makes use of a first order time polynomial with complex coefficients for capturing ...

distribution of water vapor in the atmosphere of the room poultry houses is usually an effective and economical solution to reduce heat stress of the chickens. experimental studies were conducted in a small saloon located in the farm machinery department of shiraz university. the rotary cup fogging system consisted of a cup which was derived by dc motor. rotational speed of the cup caused the w...

In this paper, we study the asymptotic distributions for least-squares (OLS), fully modi ed (FM), and dynamic OLS (DOLS) estimators in cointegrated regression models in panel data. We show that the OLS, FM, and DOLS estimators are all asymptotically normally distributed. However, the asymptotic distribution of the OLS estimator is shown to have a non-zero mean. Monte Carlo results examine the s...

The abhorent effect of GHG emissions effects pushes nations to consider effective policies and take initiatives accordingly inorder maintain the surface temperature at steep level. Practitioners, Policymakers other regulators in this regard are urging firms behave environmental friendly way through increased usage energy effeciency such as increasing renewable consumption minimizing carbon emis...

Two modifications of Malmstrom's cup were used in a study of the position of the cup in 500 vacuum extractor deliveries. The incidence of completely flexing applications varied from 0 to 92 per cent according to the level of the head and the position of the occiput when the cup was applied and, in occipito-posterior positions, the type of cup that was used. With mid-cavity occipito-posterior po...

Communication networks are important infrastructures in contemporary society. There still many challenges that not fully solved and new solutions proposed continuously this active research area. In recent years, to model the network topology, graph-based deep learning has achieved state-of-the-art performance a series of problems communication networks. survey, we review rapidly growing body us...

This study documents the development of fetal heart rate (FHR) change in response to fetal movement (FM) in healthy fetuses from 20 weeks' gestational age through term. Thirty-one fetuses received 50 min of Doppler-based monitoring at 20, 24, 28, 32, 36 and 38-39 weeks. FHR and FM were continuously digitized. A coupling index was computed as the percentage of FMs associated with increases in FH...
