Accurate Speech endpoint detection is important for speaker recognition, speech recognition, coding, and transmission and so on. In this paper, a fusion feature is proposed for speech endpoint detection, which utilized zero-crossing rate, Lempel and Ziv complexity (LZC), C0 complexity and fluctuation complexity to represent the speech signal. In order to classify speech signal and background signal,...
When talking about three-phase full-bridge rectifier circuit fault diagnosis, the ordinary neural network diagnosis shows its limitation on local minimum point in training process, and low diagnosis accuracy. Moreover, this kind of fault diagnosis is based on fuzzy logic and it relies too much on experience of expert through trial and error method, without self-learning capability. This paper provided...
DNA replication, a critical step in cell division and proliferation, is a process of producing two identical replicas from one original DNA molecule. Although great advances have been made in DNA replication research, the detailed mechanism of DNA replication is still unresolved. Faithful DNA replication requires the cooperation of many proteins. Failures in DNA replication leave mutations in the...
Oxidative stress can damage major cell components, including protein, DNA, lipid and cell membranes, which may make cells lose function and induce a wide variety of diseases. As an extensive kind of antioxidants in human and animals, antioxidant proteins are essential to eliminate cell damage and aging problems caused by oxidative stress. Accurate identification of antioxidant proteins is a significant...
