这是一个uwb用于体域网的信道仿真程序，可以进行仿真，它符合IEEE.802.15.4a，非常好！(This is a body area network for the uwb channel simulation program allows for simulation, it is consistent with IEEE.802.15.4a, very good!)

k-means 算法接受输入量 k ；然后将n个数据对象划分为 k个聚类以便使得所获得的聚类满足：同一聚类中的对象相似度较高；而不同聚类中的对象相似度较小。聚类相似度是利用各聚类中对象的均值所获得一个“中心对象”（引力中心）来进行计算的。(k-means algorithm accepts input k then n data objects into k clusters in order to make clustering satisfy obtained: the objects in the same cluster high similarity different clustering object similarity small. Cluster similarity is the use of the mean of each cluster of objects that get a " central object" (center of gravity) to perform the calculation.)

　　本文描述的动态行为　　并行输入/并行输出直流电流型控制　　buck-boost转换器作为multiinput /初步研究　　多输出。这个系统的主要应用之一　　是集成光伏阵列是什么时候　　连接到网格作为可再生能源的来源。的twomodule 　　变换器由两个相同的buck-boost电路　　和直流运行传导模式　　(CCM)。(the paper describes the dynamic behaviour of a parallel-input/parallel-output current-mode controlled DC-DC buck-boost converter as an initial research for multiinput/ multi-output. One of the main application for this system is the integration with photovoltaic (PV) arrays when be connected to the grid as a renewable energy source. The twomodule converter comprises two identical buck-boost circuits and operates in the continuous-current conduction mode (CCM).)

高阶拟合出光纤模式折射率和波长的关系并计算出较为准确的波导色散，同时计算出材料色散，并最终得到光纤的总色散。(The relationship between the refractive index and the wavelength of the fiber mode is fitted in higher order an the more accurate waveguide dispersion is calculated; the material dispersion is calculated at the same time, and the total dispersion of the fiber is obtained.)
