使用神经网络进行脸部识别系统
应用背景介绍了人工神经网络(ANN)方法在数字图像识别中的应用,并通过在身份验证中的人面部特征提取与识别的实例对现有网络进行了研究,提出了改进思想,以期达到降低运算量、提高识别率的目的。关键技术应用神经网络技术构建了一个完整的人脸识别系统.首先使用基于眼睛位置估计的方法从人脸图像中分割出对识别有意义的纯脸,然后使用自组织映射进行特征压缩,提取有效的鉴别特征.最后使用基于知识的模糊神经网络进行分类.在NUSTDBII人脸数据库上的实验得到了令人满意的结果,并且表明该方法对人脸的姿态及表情有一定的不敏感性.

massive mimo THP algrorithm
应用背景On the Design of ZF and MMSE Tomlinson-Harashima Precoding in Multiuser MIMO Amplify-and-Forward Relay System,it is main described the mimo system in the multi-user scenario.the main precoding algrithm is combined the zf precoding and the MMSE precoding.关键技术we design a zero-forcing (ZF) Tomlinson-Harashima precoding (THP) and a minimum mean
square error (MMSE) THP for multiuser MIMO relay system with direct link. Based on these precoding structures, we propose the optimal combining weights of the ZF THP and the MMSE THP in half duplex relay system, and the sub-optimal weights of MMSE THP to reduce feedback channel state information(CSI). Through the Monte Carlo simulation, we verify that the optimal weights combining method outperforms the constant weights combining method. In addition, we confirm that the
performance of the sub-optimal weights combining method is&

umat编写Johnson-cook强化模型
Abaqus 中Johnson-cook模型只能用于explicit显示分析中,而我们需要在standard模块中可以使用的更加精细的Johnson-cook模型,故而借助Fortran来编写子程序来实现其本构关系。
