This paper proposes a digital audio watermarking algorithm based on discrete wavelet transform (DWT), singular value decomposition (SVD) and independent component analysis (ICA). Firstly, it preprocesses original audio to select the appropriate fragments to embed watermark when embedding a watermark. It uses three level wavelet transform to the original audio and singular value decomposition to the...
Mitochondria are essential organelles for neuronal survival and function through ATP generation, calcium buffering, and apoptotic signaling. Due to their extreme polarity, neurons utilize specialized mechanisms to regulate mitochondrial transport along axons to areas in which energy production and calcium homeostasis are in high demand, namely, active growth cones, nodes of Ranvier, and synaptic terminals...
A complementary micro-grid power system including wind power, photovoltaic system, diesel generator and battery storage based on altering-current bus is designed in this paper. Various operation modes and working states of the system are concluded according to its energy flowing and operation characteristics. A coordinated operating control scheme is also proposed in the paper. The scheme guides the...
In order to overcome the shortcoming of Fuzzy C-means (FCM) that can not deal with image noise and weaknesses of its common improved algorithms, an improved FCM algorithm using the difference of neighborhood information is proposed in the paper. The algorithm uses the Gaussian function to characterize the differences of space and gray level of neighborhood pixels reasonably, to realize the adjustment...
In this paper, we introduce a software platform which can simulate and study the countermeasure between the terminal guidance missile and the warship. A criterion for evaluating effectiveness of chaff jamming is studied and requirements of chaff RCS are discussed. Strategies of spreading chaff cloud and elusion of the warship are studied and verified by simulation results.
Based on auditory masking effect, WAV format audio signal is programmed to embed a DWT (discrete wavelet transform) efficient digital watermarking algorithm of WAV format VF watermarking, conducting the embedding of the watermarking, extraction and anti-piracy properties research by using Matlab7.0 programming. Simulation results show that VF watermarking, embedded in the algorithm has good imperceptibility,...
For detecting the validity of the new tactics use and jamming method for the radar, the simulation model for the active radar is built. The configuration of the simulation is introduced. The attendant question and the pursuant theory on building the simulation model is analyzed. The control and guide of the missile, ship moving, jamming process on the chaff rocket can be simulated using the model...
The best launch method can be given by arranging the launch time and jamming rocket sort for the emplacements because the relative position, range and jamming rocket number of the emplacements are different in the launcher. A reinforce launch algorithm is proposed based on the characters of the firepower intersection and tracking.
