文章讨论了利用超声以及一种物理模型来研究松质骨的健康状况。(A physical model for broadband ultrasonic studies of cancellous bone)

使用误差累计的方式，来实时的更新背景，提取出最新的背景，(Cumulative manner using the error to the background of real-time update, extract the latest background)

基于自组织神经网络的矢量量化编码Ｍatlab程序(Based on self-organizing neural network vector quantization coding Matlab procedures)

在处理图像增强的时候，运用的分割技术，代码简单。(When dealing with image enhancement, using the segmentation technique, the code simple.)

对脑电信号的时域波形进行阈值检测，识别特征脑电(EEG time-domain waveform threshold detection )

反激变换器的电压闭环PI控制，输出稳定，可以学习(Flyback voltage loop PI control, stable output, you can learn)

使用个股日内髙频收益率计算己实现值进行分析,同时计算得到二阶矩 和高阶矩值并进行对比。本文根据己实现量的大小将所有样本股分为己实现值由 小到大的姐别,分别跟踪各股票组合的收益,探索预期收益与个股己实现值之间 的变化关系,然后将分组的结果应用于多空策略,为提高资产配置收益提供参考。 同时,将各己实现变量和各类对预期收益产生影响的控制变量放在一起构建 Fama-MacBeth截面回归,分析高频已实现量是否具有定价能力。(The realized value is calculated by using the daily gust rate of return of individual stocks, and the second-order moments are obtained by calculating at the same time. Comparisons are made with higher order moment values. This paper divides all sample stocks into realized values according to the size of realized stocks. Sisters from small to large track the earnings of each stock portfolio, and explore the relationship between expected earnings and the realized value of each stock. Then the grouping results are applied to the multi-empty strategy to provide reference for improving asset allocation returns.)
