Acoustic modelling can be informative in the analysis and design of room and concert hall acoustics. There are two types of acoustic models, geometric and wave-based. Geometric models assume sound propagation is ray-like and therefore suited to high frequency room impulse response (RIR) estimation. Wave-based methods are founded on a discrete numerical solution to the wave equation and are ther...

chicken anemia virus was detected by pcr in tissue samples collected from poultry flocks in gujarat,india. the vp1, vp2 and vp3 gene sequences of cav from anand, gujarat were obtained after cloning thepcr products in pdrive cloning vector. nucleotide sequence alignment with other cav sequencesdemonstrated overall identity of 95-98.8%, 98.8-99.8% and 98.8-100% for vp1, vp2 and vp3 regions,respec...

A promising approach for speech dereverberation is based on supervised learning, where a deep neural network (DNN) trained to predict the direct sound from noisy-reverberant speech. This data-driven leveraging prior knowledge of clean patterns, and seldom explicitly exploits linear-filter structure in reverberation, i.e., that reverberation results linear convolution between room impulse respon...

A series of experiments was conducted to investigate migration, proliferation and differentiation of gonadal germ cells (GGCs) collected from the gonads of 7-day-old chick embryos under cross-sex germline chimera conditions. The migratory and proliferative abilities of exogenous GGCs were examined by transferring 50 fluorescently labeled GGCs collected from White Leghorn (WL) embryos into the b...

Starting from an hypothesis concerning the long-term effects of exogenous treatment during the ontogeny of mammals and birds, we incubated Rhode Island Red (RIR) eggs at different prenatal temperatures (table 1) to study the feed efficiency, development, reproduction and energy metabolism of the hens. The maintenance requirement varied (up to 30 p. 100) as well as the feed conversion (up to 28 ...

An advanced dielectric function has been designed to compute the photonic band structures of non-close-packed inverse opals fabricated using conformal infiltration and by a recently described sacrificial-layer technique. A model is proposed to correctly simulate complex dielectric structures resulting from conformal backfilled infiltrations. While large photonic band gaps PBGs and a reduced ref...

The purpose of room impulse response (RIR) reshaping is to reduce reverberation and thus to improve the perceived quality of the received signal by prefiltering the source signal before it is played with a loudspeaker. The optimization of an infinityand/or p-norm based objective function in the time domain has shown to be quite effective compared to leastsquares methods. There are, in general, ...

The vulnerability of the Internet has been demonstrated by prominent IP prefix hijacking events. Major outages such as the China Telecom incident in 2010 stimulate speculations about malicious intentions behind such anomalies. Surprisingly, almost all discussions in the current literature assume that hijacking incidents are enabled by the lack of security mechanisms in the inter-domain routing ...
