主从多机通信系统可靠性建模，对一个主从多机系统进行建模分析，其中基本单位为元件，有着不同的概率分布寿命，不同元件串联组合成不同部件，部件组合成各分系统，从而根据元件情况可推定系统状态，我们会计算十年中系统地各项指标，推断时间步长为1小时(Master-slave multi-machine communication system reliability modeling, a master-slave multi-machine system modeling and analysis, in which the basic unit for the components, the probability distribution of different life, a different tandem combination of components into different parts, components into subsystems , so the situation could be construed in accordance with the system components, and we will calculate ten indicators in a systematic manner, inference time step 1 hour)

Surfmatch is a method to post publicity without taking account of the usual methods like that to show postings near the search engines or to record publicity on advertizing sites. Here is the word locates: behavioral targeting

作为一个有吸引力的技术， 减轻多径干扰的正交频 分复用（OFDM）已经被广泛应用 在各种广播系统，诸如数字 视频广播（DVB）系统。尽管它的竞争力 属性，OFDM信号的特点是非常高的 峰值对平均功率比（PAPR）的水平。( As an attractive technique in mitigating the multipath interference, Orthogonal Frequency Division Multiplexing (OFDM) has been widely applied in various broadcasting systems such as, the Digital Video Broadcasting (DVB) systems. Despite its competitive attributes, OFDM signals are characterized by very high Peak-to-Average Power Ratio (PAPR) levels.)

matlab编写的元胞自动机，粒子图像分割及匹配均为自行编制的子例程，研究生时的现代信号处理的作业。( matlab prepared cellular automata, Particle image segmentation and matching subroutines themselves are prepared, Modern signal processing jobs when the graduate.)

利用SVM做回归线性测试。对于大盘指数的有效预测可以从整体上观测股市的变化提供强有力的信息，所以对上证指数的预测很有意义。通过对上证指数从1990.12.20-2009.08.19每日的开盘数进行回归分析，最终拟合的结果是：均方误差MSE=2.35705 e-005，平方相关系数 R=99.9195 。SVM的拟合结果还是比较理想的。(Make use of SVM linear regression testing. For the market index can predict the observed changes in the stock market as a whole to provide a strong information, so it makes sense to predict the Shanghai index. Through the Shanghai Composite Index opened daily from 1990.12.20-2009.08.19 number of regression analysis, the results of the final fit are: mean square error MSE = 2.35705 e-005, the square of the correlation coefficient R = 99.9195 . SVM fitting result is quite satisfactory.)
