Acoustic signalling in Orthoptera [PDF]
, 2021 Acoustic communication is one of the most well-known behavioural traits of the Orthoptera. Orthopteran insects and the sounds they produce are both extremely diverse, and species-specific sounds are an extremely important tool in orthopteran taxonomy and systematics. For most species, acoustic signalling is the most important means of communication. It

Variable Scale Relative Entropy Detection for Non-Cooperative Underwater Acoustic Pulse Signals
IEEE Access, 2020 This work investigates the detection of non-cooperative underwater acoustic pulse signals at low signal-to-noise ratio (SNR). A variable scale relative entropy (VSRE) pulse signal detection scheme is proposed. Different from conventional relative entropy
