Based on existing test methods of sulfate attack concrete,the test method of sulfate attack concrete under sub-high temperature environment was put forward,and the specimen size,the sulfate solution and concentration and the macroscopic and microcosmic index are determined.
在总结现有混凝土硫酸盐侵蚀试验研究的基础上,提出了考虑亚高温水淬与硫酸盐侵蚀双因素影响的亚高温环境下混凝土耐硫酸盐侵蚀试验方法,确定了试件尺寸、侵蚀溶液及其浓度、宏观和微观测试指标等。
The performance of existing blind source separation methods is highly affected by the non-linear contrast functions that are selected according to the distribution of original signals, and the separation results are not always ideal, especially for the mixture of super-Gaussian signal and sub-Gaussian signal.
对模拟信号的分离结果表明,该算法可以成功地分离混叠信号,同时与快速独立分量分析算法相比,该算法的性能对源信号的概率密度性质没有依赖,因而对亚高斯和超高斯信号的混合信号表现出更加优异的分离能力。
In this paper,sub-Gaussian random projection is introduced into compressed sensing(CS) theory and two new kinds of CS measurement matrix:sparse projection matrix and very sparse projection matrix are presented.
将亚高斯随机投影引入可压缩传感CS(compressed sensing)理论,给出了两种新类型的CS测量矩阵:稀疏投影矩阵和非常稀疏投影矩阵。
In order to separate super-Gaussian and sub-Gaussian signals,this paper uses high-and low-frequency coefficients of wavelet transform as smooth factors,then builds a signal-to-noise ratio objective function,which uses the denominator as prediction error and can be optimized to resolve separable matrix.
为了分离超高斯与亚高斯信号,利用小波变换的高低频系数作为平滑因子,建立以分母作为预测误差的信噪比目标函数,优化目标函数以求解分离矩阵。
