假设一个点目标在x，y平面上绕单位圆做圆周运动，由于外界干扰，其运动轨迹发生了偏移。其中，x方向的干扰为均值为0，方差为0.05的高斯噪声；y方向干扰为均值为0，方差为0.06的高斯噪声。 已设计一FIR维纳滤波器，选择Kalman滤波器进行滤波处理，确定最佳传递函数，并用该滤波器处理观测信号，得到其最佳估计。(Assume that a point target moves circularly around the unit circle in the x, y plane, and its movement trajectory shifts due to outside interference. Among them, the interference in the x direction is Gaussian noise with a mean of 0 and a variance of 0.05; the y-direction interference is Gaussian noise with a mean of 0 and a variance of 0.06. An FIR Wiener filter has been designed. The Kalman filter is selected for filtering, the best transfer function is determined, and the filter is used to process the observed signal to obtain the best estimate.)

圆度测量中用fft和ifft滤波,由于传统的rC滤波和2RC滤波.简单使用-Roundness measurement using fft and IFFT filtering, due to traditional rc 2RC filtering and filtering. Simple to use

一个Delphi写的收费管理系统，界面方面做的漂亮，不过使用有第三方控件，功能不多，都是比较常用的功能，比如查询交费、收费统计、数据交换等。源码由安徽财经大学计算机系冰逸工作室提供，系统登录用户名001 　　密码123。

2008 年，一本讲述生死轮回的小书《前世今生》跃上美国亚马逊书店畅销书排行榜，其热度至今仍炽。细心的读者却发现，这本书早在20 年前就已经震惊全世界，在心理学领域内更是掀起了一场有关轮回转世的辩论风暴！(many lives many masters)

一本非常NB的关于计算机的离散数学与应用书籍！(Discrete Mathematics and its Applications is a focused introduction to the primary themes in a discrete mathematics course, as introduced through extensive applications, expansive discussion, and detailed exercise sets. These themes include mathematical reasoning, combinatorial analysis, discrete structures, algorithmic thinking, and enhanced problem-solving skills through modeling. Its intent is to demonstrate the relevance and practicality of discrete mathematics to all students. The Fifth Edition includes a more thorough and linear presentation of logic, proof types and proof writing, and mathematical reasoning. This enhanced coverage will provide students with a solid understanding of the material as it relates to their immediate field of study and other relevant subjects. The inclusion of applications and examples to key topics has been significantly addressed to add clarity to every subject. True to the Fourth Edition, the text-specific web site supplements the subject matter i)

扫雷游戏先说下原理，原理其实很简单，设法获得“雷区”的数据，然后通过模拟鼠标动作，点击雷区上非地雷的的格子，就搞定了:) 所以技术难点只有三个：获得雷区数据、找到扫雷程序和模拟鼠标动作。 -game

这是问道etc的打包解压工具，你可以自己进行操作(This is the packing and decompression tool that asks etc)
