Description: 南方CASS软件中只能采用数据批量生成断面里程文件，而工作中往往需要对三角网进行修改以便更加符合实际地形。而CASS中没有根据三角网批量生成断面里程的功能，只能一条一条的切出来，工作量十分巨大。以小野的工作来看，在包含几十万个三角网的CAD图形中根据三角网单独切断面，每条断面里程文件的生成需要约十秒左右的时间，不仅工作量巨大，而且十分考验人的耐心和细致。终于，有一天小野忍受不了那个速度，就写下了这个小程序。因为仅是为了实际工作需要，所以没有花时间去做界面。经测试，125361个三角形构成的三角网运行时间约为5分08秒，而对应的根据数据批量生成里程文件约需57分钟。因此该算法效率较高，能很好的提高实际工作效率。-the South CASS software can only use the data generated batch file section mileage, but the work often requires modification of the triangular mesh in order to more realistic terrain. The CASS is not generated under the triangular cross-section volume function of mileage, only one one of the cut out, the workload is enormous. To Ono s work point of view, contains hundreds of thousands of triangulation, in accordance with the CAD graphic triangulation single cut surface of each section of the file generated mileage of about 10 seconds or so the need is not only a huge workload, but people are tested patience and meticulous. Finally, one day, Ono could not bear that speed, they wrote this little program. Because it is only to actual operational needs, we do not take the time to do interface. The test, consisting of 125,361 triangles triangular mesh running time is about 5 minutes 08 seconds, while the corresponding quantities of data generated under the mileage of the file will take abou

Description: 局域网仿真是局域网设计的重要环节，也是网络性能分析的关键。
计算机局域网设计、模拟和性能分析系统的研究是一个非常有意义的课题。它使设计者在设计阶段就能对所设计的网络的性能作出准确的预测，合理修改其设计，选择符合要求的性价比较优的方案。进行计算机仿真，利用仿真中间参数分析系统性能是分析某一计算机网络系统的性能的常用方法。采用系统仿真的方法，能对各组件的行为进行较精确的模拟，获得足够数据来对系统的性能进行较准确的预测。
在构造一个局域网之前，需要设计此网络的拓扑图，各层协议等等。要达到最优的效果，需要对图的结构等等进行不断的修改。如果用手工计算、调整，则不仅耗功耗时，还可能留下不可预计的漏洞。而要直接进行操作系统上的编程工作，则不断的修改、调试让人无法忍受，更重要的是由于实际机器的影响，很多工作都无法进行。
类似的情况发生在我们研究网络算法时，如果直接在各种操作系统上编程、测试，便无可避免与操作系统内核打交道。这需要特别熟悉操作系统的内核，操作系统内核的复杂性大大增加了编程的难度，这使我们将更多的精力投入对操作系统的编程而不是对算法的研究。

Description: 在科学技术、经济管理中常常要按一定的标准（相似程度或亲疏关系）进行分类。例如，根据生物的某些性状可对生物分类，根据土壤的性质可对土壤分类等。对所研究的事物按一定标准进行分类的数学方法称为聚类分析，它是多元统计“物以类聚”的一种分类方法。由于科学技术、经济管理中的分类界限往往不分明，因此采用模糊聚类方法通常比较符合实际。-In science and technology, economic management, often according to certain criteria (similarity or closeness) classification. For example, according to some biological traits may be of biological classification, according to the nature of the soil on soil classification can be. Studies on the classification of things according to certain standards of mathematics known as cluster analysis, it is a multi-Statistics " Like attracts like" a classification. As science and technology, economic management in the classification boundaries are often not clear, so the fuzzy clustering methods are usually more realistic.

Description: 功能：
可以将一般的琴谱转换成win7小工具里面可用的琴谱！
原理：
常规的琴谱都是按a,b,c,d......排音高的，而win7小工具里面那个钢琴是按键位来排的（这样可能更符合实际情况，让我们更加能找到弹钢琴的感觉~），所以这个程序所做的就是一个简单的替换~将a替换成[cap]（caps lock键）,b替换成a键。。。。。。（注：[enter]是回车键，[pg dn]是上翻页！）
bug：
由于钢琴的键是要比我们键盘的要长得多，所以win7小工具里那个钢琴是只有中音和高音，而没有低音和超高的，所以部分音没有对应的键，比如低音中的a－g，超高中的v－z，这些键一率用中括号括起来，以示区别！
使用：(注意，转换后会覆盖原始文件，请先备份！！)
进入cmd，cd到当前目录，输入：
piano 送别.txt
转换完毕，下面是转换结果示意，[G]，[A]就是没有对应键位的低音：
fsfj gjf
f[Cap]as a[Cap]a
fsfj hgjf
fasd [G][A]-change the general sheet music into the win7 gadget sheet music!

Description: 几何学研究的对象是客观世界中物体的形状。传统欧氏几何学的研究对象，都是规则并且光滑的，比如：直线、曲线、曲面等。但客观世界中物体的形状，并不完全具有规则光滑等性质，因此只能近似当作欧氏几何的对象，比如：将凹凸不平的地球表面近似为椭球面。虽然多数情况下通过这样的近似处理后，能够得到符合实际情况的结果，但是对于极不规则的形态，比如：云朵、烟雾、树木等，传统的几何学就无能为力了。
如何描述这些复杂的自然形态？如何分析其内在的机理？这些就是分形几何学所面对和解决的问题。
-The study of geometry object is the objective world in the shape of an object. Traditional Euclidean geometry object of study, all is the rules and smooth, such as: straight line, curve and surface. But the objective world in the shape of an object, not completely have rules such as smooth nature, therefore can only approximate as Euclidean geometry object, such as: will be uneven of the earth s surface approximation for an ellipsoid. Although most cases through such approximate treatment after, can get the result of the tally with the actual situation, but for very rules form, such as: the clouds, smoke, trees, the traditional geometry can do.
How to describe these complex natural form? How to analyze its internal mechanism? These are the fractal geometry to face and solve problems.

Description: 在回归分析中，如果有两个或两个以上的自变量，就称为多元回归。事实上，一种现象常常是与多个因素相联系的，由多个自变量的最优组合共同来预测或估计因变量，比只用一个自变量进行预测或估计更有效，更符合实际。因此多元线性回归比一元线性回归的实用意义更大。-In regression analysis, if there are two or more independent variables, it is called multiple regression. Indeed, a phenomenon often associated with a plurality of factors, from the optimal combination of a plurality of common variables to predict or estimate a dependent variable, compared with only one independent variable to predict or estimate more effective and practical. Multiple linear regression and therefore the practical significance of a linear regression greater.

Description: 实现功能：基8实现64点FFT处理器（进行两次8点FFT计算，采用基8进行64点）
详细说明：硬件结构包括六部分，分别为输入模块、8点FFT模块、乘法模块、顺序调整模块、输出模块和总控制模块。
其中，输入模块的主要功能是将串行输入的64个数据进行分类，分成8批次，每次8个输入到8点FFT模块中进行计算。
8点FFT模块：FFT是DFT的快速算法，当点数较大时，可以较大的减少DFT的运算量。常用的FFT算法主要有两种，分别为按时间抽选的FFT算法（DIT-FFT）和按频率抽选的FFT算法（DIF-FFT）。在我们的设计中，我们采用的是按频率抽选的8点FFT算法。
乘法模块：由于旋转因子的对称性，只需要产生8个常数因子即可。但这样会复用一些单元，从而影响运算速度，为了提高计算速度，我们分析时序情况，增加了一些单元，以实现输入数据到达之后就可以进行运算。
顺序调整模块是将第一级FFT出来的数据顺序进行调整并输出到下一级FFT模块中进行计算，数据的顺序调整情况类似于输入模块，每隔8个数取一个输出。
输出模块：由于第二级FFT模块输出数据顺序不符合实际要求，因此需要调整数据的顺序，从而使64个输出数据安装顺序串行输出，结构类似于输入模块，区别只是输入变为8个数据并行，输出为一个数据串行。-Function: base 8 implement 64-point FFT processor (twice 8:00 FFT calculation, using the base 8 of 64 points)
Description: The hardware configuration consists of six parts, namely, an input module, 8-point FFT module, multiplication module, order adjustment module, the output module and total control module.
Among them, the 64 data input module is the main function of the serial input classification, divided into eight lots, each 8 inputs and 8-point FFT module calculation.
8:00 FFT module: FFT is a fast algorithm for DFT, when a large number of points, you can greatly reduce the amount of computation of the DFT. FFT algorithm commonly used mainly two were decimated by time FFT algorithm (DIT-FFT) algorithms and FFT decimation in frequency (DIF-FFT). In our design, we have adopted is based on the frequency of lottery 8:00 FFT algorithm.
Multiplication module: Since rotational symmetry factor, you only need to generate 8 constant factor. But it will reuse some of the units, which af

Description: 考虑单片机资源以及实际工作需要，—般在255个加速台阶内完成达到最高速度的启动、加速全过程，而当实际需要的(最高)速度随每次的执行任务情况变化而改变时，我们在程序设计上就按照工作对象的最高速度计算参数表，在每次启动电机运行前恨据需要行走总步数换算出最高加速台阶数量，基本上按照三个1/3的办法去换算，即1/3的行走步数用于加速，1/3用于保持高速运行，1/3完成从高速到低速的降速停止，实现自动调速。根据实际需要也可以用2/5-1/5-2/5方案调速，使电机完成总步数的时间更短一些，也有时为了保证电机有足够的输出扭矩也可以设定一个最高限止速度参数，用来对换算所得的加速台阶数进行限制，用以防止过高速度引起的电机失步。速度的基本规律是一次运行过程形成一条典型全对称的等腰梯形，而我们的计算其所产生的速度曲线，引入了两个折点，使得在梯形斜坡上略有 S 形修正，这是符合电机特性的加速方法-Considering the resources of the microcontroller and the actual work needs, it is necessary to complete the maximum speed start and accelerate the whole process in the 255 acceleration steps, and when the actual required (maximum) speed changes with each execution task change, we The program design in accordance with the maximum speed of the work object to calculate the parameter table, before starting the motor running before the need to walk the total number of steps to convert the maximum number of steps to accelerate, basically in accordance with the three 1/3 of the way to convert,/3 of the number of walking steps for acceleration, 1/3 for high-speed operation, 1/3 to complete low to low speed to stop the speed to achieve automatic speed control. According to the actual needs can also be 2/5-1/5-2/5 program speed, the motor to complete the total number of steps shorter time, and sometimes in order to ensure that the motor has enough output torque can also set a maximum limit The

Description: 岭回归(英文名：ridge regression, Tikhonov regularization)是一种专用于共线性数据分析的有偏估计回归方法，实质上是一种改良的最小二乘估计法，通过放弃最小二乘法的无偏性，以损失部分信息、降低精度为代价获得回归系数更为符合实际、更可靠的回归方法，对病态数据的拟合要强于最小二乘法。
总之，本文档是岭回归的R语言实现代码，主要用于解决当模型中出现多重共线性问题，尤其是当你所有的解释变量都很重要，又无法通过其他检验来删除时，岭回归是一个很好的解决办法。(Ridge regression (English Name: ridge regression, Tikhonov regularization) is a kind of special linear data analysis of biased estimation is actually the least squares regression method, an improved estimation method, the unbiased least square method to give up the part of the loss of information, reduce the accuracy of regression coefficient is more practical more reliable, the cost of pathological data was stronger than that of least squares fitting.
In short, this document is a ridge regression of the R language code, mainly used to solve the multicollinearity problems when the model, especially when you have all the explanatory variables are very important, and not by other inspection to delete, ridge regression is a good solution.)
