Most state-of-the-art speech enhancement (SE) techniques prefer to enhance utterances in the frequency domain rather than in the time domain. However, the overlap-add (OLA) operation in the short-time Fourier transform (STFT) for speech signal processing possibly distorts the signal and limits the performance of the SE techniques. In this study, a novel SE method that integrates the discrete wa...

overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (copd) and obstructive sleep apnea (osa), was first defined by flenley. although it can refer to concomitant occurrence of any of the pulmonary diseases and osa, overlap syndrome is commonly considered as the coexistence of osa and copd. this disease has unique adverse health consequences distinct from ...

According to Barlow's seminal "efficient coding hypothesis," the coding strategy of sensory neurons should be matched to the statistics of stimuli that occur in an animal's natural habitat. Using an automatic search technique, we here test this hypothesis and identify stimulus ensembles that sensory neurons are optimized for. Focusing on grasshopper auditory receptor neurons, we find that their...

Speech intelligibility in public places can be degraded by the environmental noise and reverberation. In this study, a new near-end listening enhancement (NELE) approach is proposed which using time varying filter jointly enhances onsets reduces overlap masking. For optimization, some look-ahead clean speech prior knowledge of room impulse response (RIR) are required. method, optimizing defined...

Direct numerical simulations of turbulence are optimized for up to 192 graphics processors. The results from two large GPU clusters are compared to the performance of corresponding CPU clusters. A number of important algorithm changes are necessary to access the full computational power of graphics processors and these adaptations are discussed. It is shown that the handling of subdomain commun...
