In this correspondence, synthetic microphone signals generated with the image model technique are used to study the eeects of room reverberation on the performance of the maximum likelihood (ML) estimator of the time delay, in which the estimate is obtained by maximizing the cross-correlation between ltered versions of the microphone signals. The results underscore the adverse eeects of reverbe...

avian infectious bronchitis (ib), caused by a gammacoronavirus, is an oie-listed (list b) disease and characterized by respiratory and renal involvements, causing high mortality, and economic loss in both layers and broilers. in comparison with other diagnostic methods, real-time polymerase chain reaction (rt-pcr) and conventional rt-pcr are potent, more sensitive and faster techniques for infe...

background: parasitic nematodes cause animal and human diseases of major socio-economic importance worldwide. the suppression of parasite development at particular developmental stages could provide an alternative approach for nema-tode control. in this study, ascaris suum was used as a model system in the study of the differentially expressed genes in the infective l3 stage. methods: the gene ...

A theory is developed for generating short time, monostatic reverberation realizations caused by three-dimensionally distributed volume inhomogeneities in stratified media. A wave number integral approach to treating the propagation to and from the scatterers, combined with a two-dimensional spectral representation of the azimuthally averaged scatterer realizations and a novel numerical impleme...

This paper investigates the reverberation time estimation methods which employ backward integration of adaptively identified room impulse responses (RIRs). Two kinds of conditions are considered; the first is the "ideal condition" where the anechoic and reverberant signals are both known a priori so that the RIRs can be identified using system identification methods. The second is that only the...

Head-related impulse responses measured in a classroom are used to generate realistic “reverberant” inputs to a physiologically-based model of binaural processing in the brainstem. Results show that instantaneous information provides relatively poor source direction information, even though human perception is only slightly affected by reverberation. However, analyses of the distortion of spati...

When perceiving speech, listeners compensate for reverberation and stable spectral peaks in the speech signal. Despite natural listening conditions usually adding both reverberation and spectral coloration, these processes have only been studied separately. Reverberation smears spectral peaks across time, which is predicted to increase listeners' compensation for these peaks. This prediction wa...
