In this paper, we propose an enhanced adaptive muting method using a sigmoid function, which is based on a parameter tracking technique for the packet loss concealment algorithm of ITUT G.722 speech codec. The packet loss concealment algorithm performs an adaptive muting to prevent the generation of unnecessary noises or clicks during packet loss recovery. While a conventional muting method app...

Currently, artificial neural networks (ANN) are being applied to livestock production as alternatives to regression analysis for forecasting egg prices [1, 2], selecting the feed mix in the feed industry [3], and predicting the amino acid composition of feed ingredients [4, 5]. The advantages of ANN have been reported. Unlike regression analyses, ANN do not require that a mathematical model be ...

PURPOSE A youthful female upper eyelid contour includes a concave medial portion of the upper eyelid along with a fuller, convex lateral eyelid. The skin in the lateral eyelid is tight without hooding. This is a sigmoid shape in 3-dimensional terms. With aging, fatty herniation medially along with redundant, hooded, ptotic lateral skin creates the exact opposite eyelid curve. The sigmoid blepha...

BACKGROUND Although intravenous morphine titration is widely used to obtain rapid and complete postoperative pain relief, the relationship between measurement of pain and morphine requirements varies, and the evolution of pain during titration is poorly understood. METHODS Intravenous morphine titration was administered as a bolus of 2 (body weight < or = 60 kg) or 3 mg (body weight > 60 kg) ...

The process related to the changes in dimensions and mass of grape berry passes through two growth phases separated by a lag phase, can be described double sigmoid curve. onset their duration are important factors for understanding processes berries. A new method quantitative determination was developed present study. In this method, phase transition dates correspond times at which rate change ...

Dose-response relationships for incidence are based on quantal response measures. A defined effect is either present or not present in an individual. The dose-incidence curve therefore reflects differences in individual susceptibility (the "tolerance distribution"). At low dose, only the more susceptible individuals manifest the effect, while higher doses are required for more resistant individ...

The unprecedented demand for testing the ongoing coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome 2 has led to an shortage and limited availability of test reagents which pooling samples been recommended in areas with low prevalence. Considering possibility dilution factor pool testing, attempt was made find out any true positive pools late amplification....
