during 2010-2011, real-time pcr procedure was used to detecting fmdv rna on 147 epithelium samples from the field. in this survey, for real-time pcr from 3d gene segment as conserve region selected for tracking all of seven serotypes fmdv. the assay detected the viral rna in all serotypes of fmdv. the rrt-pcr specifically detected fmd virus in sample with greater sensitivity than our convention...

To overcome the problems related with the long impulse responses produced by reverberation, we use a long time window (high frequency resolution) analysis during the channel normalization steps of the feature extraction process in automatic speech recognition (ASR). After nor-malization, a trade between frequency and time resolution is used to increase the rate at which the time information is ...

Room impulse responses(RIRs) have conventionally been used to derive acoustic parameters to assess acoustics of rooms. One of these parameters is reverberation time which is taken as a crucial measure for perceptual reverberance. Although this measure is not perfect on evaluation reverberance in many situations, especially when the sound decays are not exponential. This study investigates the r...

The Multiple Signal Classification (MUSIC) algorithm has become one of the most popular algorithms for estimating direction-of-arrival (DOA) multiple sources due to its simplicity and ease implementation. Spherical microphone arrays can capture more sound field information than planar arrays. collected multichannel speech signals be transformed from space domain spherical harmonic (SHD) process...
