Nios II 设计。Nios II处理器的使用(Nios II Design)

认知无线电是一种用于提高无线电通信频谱利用率的新的智能技术. 首先简述认知无线电的背景和概念,针 对认知无线电的频谱感知功能,详细地分析基于能量检测的频谱检测方法,在此基础上研究了噪声方差的不确定 性对检测性能的影响. 针对无线信号检测具有本地局域性和能量检测存在信噪比极限的特点,提出一种分布式有 限合作检测机制,推导出基于“OR”规则的有限合作机制的检测概率,并进行Monte Carlo仿真.(Cognitive radio is a radio communications spectrum used to improve the efficiency of the new smart technology. First, the background and outlined the concept of cognitive radio, spectrum sensing for cognitive radio capabilities, a detailed analysis of the spectrum based on energy detection test In this study the noise variance based on the uncertainty of the detection performance. for wireless signal detection with local detection of localized and there is signal to noise ratio limit of the energy characteristics of a distributed cooperative detection mechanism, derived out based on " OR" rules of the detection probability of the limited cooperation mechanism and conduct Monte Carlo simulation.)

通过切身休体会，总结了一些关于制作电子期刊的小技巧，供大家方便使用。(Break through personal experience, summed up a number of electronic journals on the production of tips for your convenience.)

此篇文章为虚拟机实验指导书系列文章之一，讲解了(VMware)虚拟机相关产品安装配置和一般应用，企业及应用等多个方面，(This article is a virtual machine instructions series of experiments to explain the (VMware) install and configure the virtual machine related products and general applications, enterprise and application in many areas,)

最近 LCC 谐振变换器备受关注，因为它优于常规串联谐振变换器和并联谐振变换器：在负载和输入变化较大时，频率变化仍很小，且全负载范围内切换可实现零电压转换（ZVS）。本文介绍了LLC型谐振变换器的分析方法，回顾了LLC型谐振变换器的实际设计要素。其中包括设计变压器和选择元器件。采用一设计实例，逐步说明设计流程，有助于工程师更加轻松地设计LLC谐振器。(Recently LCC resonant converter has attracted much attention, because it is better than that of the conventional series resonant converter and parallel resonant converter in the load and input change, frequency change is still very small, and the whole range of the load switch can realize zero voltage switching (ZVS). In this paper, the analysis method of LLC resonant converter is introduced, and the practical design elements of LLC resonant converter are reviewed. Including the design of transformers and components. A design example is used to explain the design process step by step, which is helpful for engineers to design LLC resonators more easily.)

这是一本关于安全技术和程序设计的好书。 This book is for anyone who wants to create efficient code。(This is one of the security technology and procedures designed books. This book is for anyone who wants to create efficient code.)

讲解了如何三维视觉的一些介绍，包括如何理解坐标变换。(Some introductions on how to use three-dimensional vision, including how to understand coordinate transformation, are explained.)

这本书很可能让你以为又是一个科学幻想，可能你会说，同类的东西已经看得太多了。 因此，你现在也许会错过这本书，但是，将来你一定会拼命去找这本书，而那时就太晚了。 我的同事告诉我，她看过一个关于超级智能机器的影片。一开始，它们随意屠杀人类。我问她，影片后来结局是什么？她说，机器人被人类感动了，成了人类的朋友。于是我再问她，人类会被蚊子感动吗？会和岩石成为朋友吗？想象远远不及真实！于是，她陷入了沉思…… 一般的科幻片中描述的人工智能机器，它们虽然在很多方面强于人类，但是，总体和人类的差距不大，大致也就是人类和狗的差距。那么，它们最后被人类感动，会和人类成为朋友是很合理的。就像人类会被狗感动，和狗成为朋友一样。但是，那也许只是20或者40年后的智能机器的情况。 不远的将来，人工智能机器的智能将是人类的万亿个万亿倍，它们面对我们，并不像我们面对狗，而是如同我们面对蚊子、跳蚤甚至岩石，当它们消灭我们的时候，如同我们将蚊子拍死，将臭虫冲进下水道，谁会在消灭跳蚤的时候觉得这样太残忍了呢？！ 这也许是人类逃脱不了的宿命，也是德·加里斯教授认为有责任写这本书，我们认为有责任出版这本科学伦理图书的原因。(This book is likely to make you think it is a science fiction, perhaps you may say, the same thing has seen too many. Therefore, you may now miss this book, but in the future you will be hard to find this book, and then it s too late. My colleague told me that she saw a movie about super-intelligent machines. Beginning, they are free to slaughter humans. I asked her later what the ending movie? She said that the robot touched by humans, became the friend of mankind. So I ask her, touched by humans by mosquitoes do? Council and rocks become friends? Imagine far less true! So she mused... A general description of science fiction artificial intelligence machines, although in many respects they are stronger than humans, however, little difference between the overall and humans, which is roughly the gap between humans and dogs. Well, they finally touched by humans, and humans will become friends is very reasonable. Just like humans dogs will be moved, and the dog became friends. But that)
