Acupuncture, including the manual acupuncture, electroacupuncture and cutaneous electrical stimulation on acupiont, is known to enhance the gastric motility. The aim of this paper is to study the changes in electrogastrogram (EGG) when the acupiont Zusanli is stimulated cutaneously by electrical signal of mid-frequency. The result shows that the regularity(More)
Cochlear Implant bypasses damaged hair cells and stimulates the auditory nerve directly in the cochlea. Wavelets are especially useful for speech processing of CI, since in the case of wavelets one speaks of a constant-Q filter bank as well as the cochlea. In this paper, a continuous wavelet has application in the filter bank design and an effective result(More)
In conventional analysis of electrogastrogram (EGG), the time percentage of normal slow waves is used to assess the regularity of the slow waves. A new parameter termed relative power percentage of normal slow waves is proposed in this paper to assess the regularity of slow waves from the view of power. Furthermore, the time and relative power percentage(More)
A cochlear implant is a new device to be implanted in the inner ear and restore partial hearing to profoundly deaf people. This article first presents the acoustic simulation principle based on CIS speech processing strategy, and then proposes an improved speech synthesis model of this acoustic simulation. Finally, on the basis of acoustic simulation(More)
The transient evoked otoacoustic emissions (TEOAEs), elicited by a transient sound, is similar to the impulse (or white noise for a random process) response of a system. It fully reveals the information of cochlea in frequency domain. The aim of present study is to apply the autoregressive (AR) spectrum analysis to TEOAEs signal in our OAEs detection system(More)
Amplitude and Sample entropy are independent features of electroencephalography. They could reflect cerebral states in different aspects: amplitude denotes the intensity of synchronous neural activities in cortex while SampEn represents the signal complexity of these bioelectrical processes. Yet both of them have limits when applied to estimation of(More)
