For Design a shock free nozzle(code for design)

包含了matlab编程基本教程及多个编程实验内容(Contains the experimental content of the basic matlab programming tutorial and multiple programming )

QPSK的调制解调系统的实现，程序详细给出了调制解调各个部分的方法。自己在matlab上实现过，都出来了(QPSK modulation and demodulation system implementation, the program details the various parts of the modulation and demodulation method. Their implementation in matlab too, are out)

该程序是描述线程的,能够帮助初学者更好的理解线程的实现过程。(this program is about thread in Java.)

Circles We can extend the Hough transform to other shapes that can be expressed parametrically. For example, a circle of fixed radius can be described fully by the location of its center (x, y). Think of each feature (edge) point on the circle as saying, ”if I’m on the circle, the center must be in one of these places”. It turns out that the locus of these votes is itself a circle. But what about circles of unknown size? In this case, we need a third parameter: the radius of the circle. So, we can parameterize circles of arbitrary size by (x, y, r). Instead of casting votes in a circular pattern into a two-dimensional accumulator, we cast votes in circles of successively larger size in a three-dimensional accumulator.

Mapping consist of QAM and QPSK modulation

The main idea behind this book, and the incentive for writing it, is that strong connections exist between adaptive filtering and signal analysis, to the extent that it is not realistic—at least from an engineering point of view—to separate them. In order to understand adaptive filters well enough to design them properly and apply them successfully, a certain amount of knowledge of the analysis of the signals involved is indispensable. Conversely, several major analysis techniques become really efficient and useful in products only when they are designed and implemented in an adaptive fashion. This book is dedicated to the intricate relationships between these two areas. Moreover, this approach can lead to new ideas and new techniques in either field.
