To improve localization accuracy, the spherical microphone arrays are used to capture high-order wavefield information. For
the far field sound sources, the array signal model is constructed based on plane wave decomposition. The spatial spectrum
function is calculated by minimum variance distortionless response (MVDR) to scan the three-dimensional space. The peak values
of the spectrum function correspond to the directions of multiple sound sources. A diagonal loading method is adopted to solve
the ill-conditioned cross spectrum matrix of the received signals. The loading level depends on the alleviation of the ill-condition
of the matrix and the accuracy of the inverse calculation. Compared with plane wave decomposition method, our proposed localization
algorithm can acquire high spatial resolution and better estimation for multiple sound source directions, especially in low
signal to noise ratio (SNR). 相似文献

A new customization approach based on support vector regression (SVR) is proposed to obtain individual headrelated
impulse response (HRIR) without complex measurement and special equipment. Principal component analysis (PCA) is
first applied to obtain a few principal components and corresponding weight vectors correlated with individual anthropometric
parameters. Then the weight vectors act as output of the nonlinear regression model. Some measured anthropometric
parameters are selected as input of the model according to the correlation coefficients between the parameters and the weight
vectors. After the regression model is learned from the training data, the individual HRIR can be predicted based on the
measured anthropometric parameters. Compared with a back-propagation neural network (BPNN) for nonlinear regression,
better generalization and prediction performance for small training samples can be obtained using the proposed PCA-SVR
algorithm. 相似文献

青海三江北段东莫扎抓铅锌矿床地质特征及找矿前景 总被引：1，自引：0，他引：1
东莫扎抓铅锌矿床隶属“三江”成矿带的北延部分,空间上与西藏玉龙斑岩铜矿床同属一个成矿带。矿区内地层由于受区域构造的控制,总体呈北西向展布,含矿地层主要为早二叠统尕笛考组,其次为晚三叠统结扎群甲丕拉组和波里掠组,断裂构造主要密集发育在早二叠世开心岭群尕笛考组（P1gd）中,各断裂彼此交错切割,具备成矿的重要通道和赋矿空间。矿区内共圈定铅锌矿体12条,矿石矿物主要为黄铁矿、闪锌矿、方铅矿;矿化有黄铁矿化、方铅矿化、闪锌矿化,同岩蚀变主要为硅化、碳酸盐化等,表现为中—低温热液成矿蚀变类型。铅锌矿体多赋存在碳酸盐岩层间破碎带中,成矿条件极为有利,具备进一步找矿的巨大潜力。 相似文献

目前我国外语听力教学存在着两种理念。第一种为听力理解法,侧重于通过听力来理解材料的意思,重点落在语言信息而非语言格式上。第二种为听力习得法,强调听在语言习得中的作用,着重突出积极注意(noticing)对语言能力发展的帮助。这两种外语听力教学理念分别导引出两种不同的外语听力课堂教学方式,给我们的外语课堂教学和教材编写造成了一定的困难和混乱。 相似文献

基于主题意义与大观念的初中英语单元整体教学是指在教师指导下,以教材为基本依托,围绕单元主题意义,从单元内容、课时学习活动和学生学习结果等方面进行系统设计和组织的教学。它不仅符合《义务教育英语课程标准（2022年版）》的基本理念,而且符合学生的认知规律,对培养学生英语核心素养有着重要意义。近年来,越来越多的教师开始重视英语大观念在教学中的运用。文章基于主题意义探究,立足大观念,对初中英语单元整体教学策略展开分析和阐述。 相似文献
