Description: A set (e.g. an image) is called "fractal" if it displays self-similarity: it can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole.
A possible characterisation of a fractal set is provided by the "box-counting" method: The number N of boxes of size R needed to cover a fractal set follows a power-law, N = N0 * R^(-DF), with DF<=D (D is the dimension of the space, usually D=1, 2, 3).
DF is known as the Minkowski-Bouligand dimension, or Kolmogorov capacity, or Kolmogorov dimension, or simply box-counting dimension.

Description: 锅炉汽包水位控制系统是火力发电厂中的一个重要的热工控制系统，汽包水位的
控制大多采用传统PID控制方式。但是，传统PID控制器参数的整定是在获取对象数学
模型的基础上，根据某一整定规则来确定的，不能进行在线调整，难以适应锅炉汽包
水位这样一个复杂多变的控制系统，其控制效果往往难以满足要求。
本文应用模糊控制技术，设计了一种二输入三输出模糊自整定PID控制器，对锅
炉汽包水位进行控制，实现了PID参数的自适应调节。利用MATLAB对控制系统进行
仿真。结果表明，该控制器自整定能力及鲁棒性比传统PID控制器更强，响应速度快、
精度高，同时对虚假水位有较好的控制效果。-Boiler water level control system is an important thermal power plant in the thermal control system, boiler water level
Control most of the traditional PID control method. However, the traditional PID controller tuning parameters for objects in mathematics
Model based on the rules to determine a whole and can not be adjusted online, it is difficult to adapt to the boiler drum
Water level control such a complex system, its control effect is often difficult to meet the requirements.
In this paper, fuzzy control technology, designed a two input and three output fuzzy self-tuning PID controller, the pot
Steam drum level control, the PID parameters to achieve the adaptive regulation. The control system using MATLAB
Simulation. The results show that the controller auto-tuning capability and robustness more than the traditional PID controller, fast response,
High precision, while the water level has better control of false results.

Description: 埃克哈特·托利（Eckhart Tolle）生于德国，从伦敦大学毕业后，他在剑桥大学担任研究员和导师。29岁那年，一次意外的开悟经历彻底改变了他的生活。在接下来的几年里，他致力于解释、整合和深化这种变化。埃克哈特·托利不倾向于任何一种宗教或传统。在他的教学当中，他用一种简单明了的语言传达了古代心灵导师的简单而深刻的信息：我们可以摆脱痛苦并进入内心的平和世界。
目前，埃克哈特·托利在世界各地旅游讲学，他努力将自己的心灵启迪实践传授给世界各地的人。自1996年以来，他居住在加拿大的温哥华。
这本书是关于埃克哈特·托利个人开悟后的感悟写的，为英文原版，希望对大家有益。-Eckhart Tolle is emerging as one of today s most inspiring teachers. In The Power of Now, already a word-of-mouth bestseller in Canada, the author describes his transition from despair to self-realization soon after his 29th birthday. Tolle took another ten years to understand this transformation, during which time he evolved a philosophy that has parallels in Buddhism, relaxation techniques, and meditation theory but is also eminently practical. In The Power of Now he shows readers how to recognize themselves as the creators of their own pain, and how to have a pain-free existence by living fully in the present. Accessing the deepest self, the true self, can be learned, he says, by freeing ourselves from the conflicting, unreasonable demands of the mind and living present, fully, and intensely, in the Now.
