This paper presents a local audio watermarking method based on the dual-tree complex wavelet transform (DT CWT) and distortion-compensated dither modulation (DC-DM).Specifically, we perform visceratuant DT CWT on extracted audio segment, and embed the watermark signal in the decomposed low-pass coefficients.During the embedding process, the selecte
The possible detrimental health effects of the inhaled radon and its decay products are in the limelight of interest of professionals as well as of the public.In the present work the passive integrated dosimeter technique with solid state nuclear track detectors (SSNTDs) super grade CR-39, was used to measure the concentration of the radioactive ra
With the increasingly serious environmental pollution, it is of great significance to st?vsugerposer aeg construct a comprehensive day-ahead dispatch model of the integrated energy system.For the regional electricity-heat integrated energy system, firstly analyze the operating characteristics and dispatch costs of all units in the system, and then
Abstract Mandibular condylar cartilage (MCC) is a multi-zonal heterogeneous fibrocartilage containing different types of cells, but the factors/mechanisms governing the phenotypic transition across the zones have not been fully understood.The reliability of molecular studies heavily rely on the procurement of pure cell populations from the heteroge
The coordinated motion of animal groups through fluids is thought to reduce the cost of locomotion to individuals in the group.However, the connection between the spatial patterns observed in collectively moving animals and the energetic benefits at each position within the group remains unclear.To address this knowledge gap, we study the spontaneo
