We were on the lookout for ice. I was in a 32 foot sailing yacht with writer and explorer Tristan Gooley, undertaking a double-handed sail from Scotland through the Faroes up to 66 33 45.7 N and the midnight sun. Now sailing out of the Arctic Circle we were approaching Iceland from the north, heading for the Denmark Straits, where ice flowed south. The Admiralty Pilot warned of bergs but the ice charts we had sailed with were over a week old. We needed an update.

Welcome to the world of wireless communications and the logical extension to the broadband architectures that are emerging as the future of the industry. No aspect of communications will be untouched by the wireless interfaces;no part of our working environment will be left untouched either. As the world changes and the newer technologies emerge, we can expect to see more in the line of untethered communications than in the wired inter- faces.

Fun. We (your authors) wanted a word to describe our ultimate goal for this book, as well as a word we hope you (our reader) will use to describe it, and that’s the one we chose. There are others goals, of course, but in the end, when you’ve finished the book, we’re hoping you’ll have enjoyed the activities described in these pages. Many books use the Introduction to explain exactly what the book is about, what the reader will learn, what the reader needs (a skill or maybe an item or piece of software), and what the reader will be left with when that last page is completed. And this Introduction will do those things, but … hopefully it’ll make you excited to get started.

Sound is simply an airborne version of vibration. The air which carries sound is a mixture of gases. In gases, the molecules contain so much energy that they break free from their neighbors and rush around at high speed. As Figure 1.1(a) shows, the innumerable elastic collisions of these high-speed molecules produce pressure on the walls of any gas container. If left undisturbed in a container at a constant temperature, eventually the pressure throughout would be constant and uniform.

The past decade has seen an explosion of machine learning research and appli- cations; especially, deep learning methods have enabled key advances in many applicationdomains,suchas computervision,speechprocessing,andgameplaying. However, the performance of many machine learning methods is very sensitive to a plethora of design decisions, which constitutes a considerable barrier for new users. This is particularly true in the booming field of deep learning, where human engineers need to select the right neural architectures, training procedures, regularization methods, and hyperparameters of all of these components in order to make their networks do what they are supposed to do with sufficient performance. This process has to be repeated for every application. Even experts are often left with tedious episodes of trial and error until they identify a good set of choices for a particular dataset.

以STC12C5A60S2单片机为控制核心,采用2.4G(JF24D)无线遥控模块进行无线发射与接收,设计了一种双电机遥控船模控制系统.该系统通过切换档杆实现前进后退,方向盘左右转动、暂停按钮等控制直流电机的正转、反转、暂停,使得电机驱动的遥控船模实现前进后退、左右转向、暂停等功能,有效解决了驱动功率小和船模之间相互干扰等问题,可广泛应用于遥控船模领域.Using STC12C5A60S2 single-chip microcomputer as the controller and 2.4 G(JF24D)wireless remote control module for wireless transmission and reception, a dual-motor remote control ship model control system is designed. The system realizes forward and backward by switching the gear lever. The steering wheel rotates left and right and the pause button controls the forward, reverse and pause of the dc motor. The remote controller of ship model driven by the motor realizes forward and backward, left and right steering, pause and other functions. The ship model control system can effectively solve the problems of small driving power and mutual interference between ship models, and can be widely used in the field of remote controller of ship model.

Allegro导出 Gerber文件和钻孔数据文件很多PCB厂家都没有装Allegro软件，所以你不能直接发.brd文件。（很多PCB小厂连ProtelDXP也没有，只支持Protel99）什么是Gerber文件Gerber文件是所有电路设计软件都可以产生的文件，在电子组装行业又称为模版文件（stencil data），在PCB制造业又称为光绘文件。可以说Gerber文件是电子组装业中最通用最广泛的文件格式Gerber文件是EIA的标准格式，分RS274-D和RS274-X两种，其中RS274-X是RS274-D的扩展文件。生产制造部门在条件许可的情况下，应当尽可能要求用户或设计部门提供RS274-X的Gerber文件，这样有利于各工序的生产准备。准备工作为了保证出片的正确性，需要在设计PCB文件之前对一些系统参数进行设置，该设置包括画图的精度，图片的尺寸，动态铺铜的格式。设置画图的精度。在allegro中打开Setup->Drawing Size菜单，调出设置对话框，如图1在对话框中确定User Units选择Mils，Size选择C，这样整个作图区域会大一点，相应的作图范围（Drawing Extents）变为Width：22000.00：Height：17000.00Left X和LeftY为原点坐标。Accuracy选择2，其他根据你的尺寸自行定义。设置完成选择OK按钮，使配置生效。
