Parameter-optimization
针对滚动轴承早期故障特征提取困难的问题，提出一种基于参数优化变分模态分解的轴承早期故障诊断方法。首先利用粒子群优化算法对变分模态分解算法的最佳影响参数组合进行搜索，搜索结束后根据所得结果设定变分模态分解算法的惩罚参数和分量个数，并利用参数优化变分模态分解算法对故障信号进行处理。(Aiming at the difficult problem of early fault feature extraction of rolling bearing, an early fault diagnosis method based on parameter optimization variational modal decomposition is proposed. Firstly, the particle swarm optimization algorithm is used to search the parameters of the variational modal decomposition algorithm. After the search, the penalty parameters and the number of components of the variational modal decomposition algorithm are set according to the obtained results. The modal decomposition algorithm handles the fault signal.)

Object-oriented-and-traditional
本书是一部实用性很强的教学用书被国外多所大学用作课堂教材。为了便于学生学习掌握，作者将本书内容分为两部分。第一部分给出了软件工程的理论基础，第二部分全面介绍了软件生命周 期的各个阶段。第二部分的一个显著特点是通过案例研究来说明有关技术。(This is a very practical book that usually be used by foreign universities for teaching. In order to facilitate students to learn and master, the book will be divided into two parts. In the first part, the theoretical foundation of software engineering is given. The second part introduces the software life cycle. A significant feature of the second part is a case study to illustrate the technology. )
