A FEM platform is developed to support high precision electric field computing and data analysis. For the precise computing of 550kV SF6 arc quenching chamber, a solve regions division project is presented to improve meshes quality and computation efficiency. At the same time, approach regular triangle algorithm is realized by combing the uniform and gradient disperse for boundary, constraint condition...
The monitoring and analysis of cattle follicle dynamics plays an important role in improving the cattle pregnancy rate, both theoretically and practically. In this paper, we demonstrate a follicle monitoring system based on 3D ultrasound image. This system integrates an image de-noising algorithm, edge detection algorithm and 3D reconstruction algorithm together using the MFC framework and OpenGL...
Traditional watermark embedding schemes inevitably modify the data in a host audio signal and lead to the degradation of the host signal. In this paper, a novel audio zero-watermarking algorithm based on discrete wavelet transform(DWT), discrete cosine transform(DCT), and singular value decomposition(SVD) is presented. The watermark is registered by performing SVD on the coefficients generated through...
Essential characteristics for watermark registration and detection without data modification can be used in anaudio zero-watermarking scheme. In this paper, a novel audio zero-watermarking scheme based on discrete wavelet transform (DWT) and discrete cosine transform (DCT) is presented. The watermark is registered by comparing the mean absolute values of the adjacent frame coefficients after DWT and...
Local Feature Extraction (LFE) algorithm is an effective feature extraction method developed in recent years. One of the shortcomings of the current LFE algorithm is that it can only process labeled data, and does not work well when the amount of the labeled data is limited. However, it is usually easy to obtain large amount of unlabeled data but only a few labeled data. In this paper, we propose...
Description logic based semantic query needs complete information from sources of knowledge where available information is often incomplete. To solve such incomplete reasoning problem, this paper embedded default logic into the description logic knowledge base, meanwhile prioritized the default rules, which preferred more specific default rules over more general ones. Then, an original incomplete...
A novel particle swarm optimization (PSO) based on chaos searching has been proposed and introduced to optimize the electrical apparatus. The improved PSO algorithm has both advantage of simplify for implement of original particle swarm optimization and advantage of fast convergence, easy to escape local minima for chaos optimization algorithm. The validity and feasibility of improved PSO algorithm...
