要积极应对网络世界的文化入侵

不久前，法国高调推出名为Quaem（拉丁语，意思为“我搜”）的搜索引擎计划，被广泛认为是拉开了一场与美国Google正面对抗的“文化保卫战”。     

基于Google搜索引擎的原理及使用

在网络时代,信息检索主要通过Internet搜索引擎进行。Internet提供了多种不同的检索工具,对用户最重要的就是熟悉这些工具的性能,掌握检索技巧,提高检索的命中率。在此从搜索引擎的工作原理开始,介绍了Google搜索引擎的使用方法,包括关键词的选择和几个检索的技巧,如逻辑检索、通配符检索等,能更快、更准确地获得所需要的信息。     

搜索引擎也是一面照妖镜

Google真的是越来越“作恶”了。听说最近Google可搜到“10年内投诉香港警方的市民资料”。过去10年投诉过香港警方的2万名市民的资料被泄漏在互联网上,外界只需通过Google搜索引擎就可以获得投诉者的姓名、住址和身份证号等个人信息,这实在是可怕。     

不打开IE也可以使用Google搜索引擎

通常情况下，人们使用Google搜索引擎，需要打开浏览器，但是前不久Google推出了一款名为“Google Deskbar”的软件，使得人们可以在不打开浏览器的情况下使用该搜索引擎。利用这种搜索方式，能节省很多时间。     

雅虎搜索市场再演奇谋暗度陈仓巧斗Google

鉴于Google的强大搜索实力。雅虎在竞争中学会了韬光养晦、欲擒故纵。而所有战术的应用。只是在宣布：雅虎永不言败[编者按]     

应用与商业结合是搜索发展的关键

知识产权等问题带来的诸多限制使得搜索引擎“异化”成为一种新的趋势。10月9日，百度宣布正式与中国工商银行达成电子商务战略联盟关系，开展一系列电子商务合作。百度地图搜索业务“十一”前夕也正式上线，对阵Google在9月推出的本地搜索……     

三思而后行乱弹Google手机绑定广告

2007年8月3日，美国《华尔街日报》报道，Google已经开发了一款原型手机，有望于一年内进入市场，并同时透露，Google准备运用一种免费的市场策略，计划通过在其搜索引擎，电子邮件和网络浏览器软件应用中绑定广告，为消费者提供免费无线服务.[编者按]     

网页嵌入式广告：网络广告的第三条道路

综观国内互联网产业十年起起伏伏，网络广告一直伴随左右，由于互联网先天就具有媒体特性，也就奠定了网络广告在网络经济赢利模式探索过程中的核心地位。从新浪、搜狐等传统门户的网络品牌广告，到百度、Google等中小企业搜索引擎关键词竞价排名广告，网络广告一直存在一个悖论，即品牌广告无法与中小企业关键词竞价排名广告无法实现完全共融，同台竞技。     

Google的“傻”

谷歌赔钱、费力做的那些根本不能赚到钱的项目，到底是为了什么呢？     

一种新的单片机"看门狗"电路软件设计方法

单片机控制系统“看门狗”电路的有效性，除硬件电路的可靠性以外，主要取决于如何正确给“看门狗”电路进行复位（即“喂狗”），文章在介绍一种采用ＭＡＸ７０６和８９Ｃ５２构成的硬件电路的基础上，给出了一种新颖可靠的“看门狗”电路软件设计方法。     

A bit is a bit is a bit?

Bits are among the most anonymous, most elusive entities in the universe. Bits weigh nothing, occupy no space, obey no physical law, can be created spontaneously from nothingness, and can be endlessly replicated. Each in itself is the merest quantum of the Information Age, yet taken together all those little 1s and 0s are acting as if they were the most important force on the planet. And if you want indestructibility, then a bit is forever. The author briefly discusses the role of the bit in today's society     

The world of silicon: it's dog eat dog [semiconductor industry]

Competition in the semiconductor industry is discussed, focusing on the changes that have taken place in the wake of the 1985 worldwide sales slump. This report is based on two pane discussions and conversations with industry veterans around the world. The following conclusions emerged: manufacturing skills the world over have reached parity; the costs of production equipment, facilities, and research and development have all skyrocketed, and only the largest of companies have the resources to remain competitive on a global basis; optical lithography is expected to be useful at least down to 0.35 μm geometries; cooperative ventures and networks of alliances are inevitable if a company wants to remain at the forefront of technology; the application-specific integrated circuit (ASIC) market has become a self-sustaining business; vertical integration is going to be a virtual necessity for any company that wants to remain a leading supplier; and the lack of truly sophisticated design tools continues to be a major hindrance to advanced IC design

人人都是摄影师 数码单反相机的全民时代

“3000元的预算,我应该选择数码单反相机还是卡片DC呢？”这一在几年前有如痴人说梦的问题在2008年却实实在在地摆在了众多消费者的面前——2008年,入门级数码单反相机的价格最低已经落到了3000元出头,甚至低于了某些消费级数码相机。于是乎数码单反相机开始以前所未有的速度进入了寻常百姓家。     

Closed-loop stimulation of hypoglossal nerve in a dog model of upper airway obstruction

Electrical stimulation of upper airway (UAW) muscles has been under investigation as a treatment method for obstructive sleep apnea (OSA). Particular attention has been given to the electrical activation of the genioglossal muscle, either directly or via the stimulation of the hypoglossal nerve (HG), since the genioglossus is the main tongue protrusor muscle. Regardless of the stimulation site or method, an implantable electrical stimulation device for OSA patients will require a reliable method for detection of obstructive breaths to apply the stimulation when needed. In this paper, we test the hypothesis that the activity of the HG nerve can be used as a feedback signal for closed-loop stimulation of the HG nerve in an animal model of UAW obstruction where a force is applied on the submental region to physically narrow the airways. As an advantage, the method uses a single electrode for both recording and stimulation of the HG nerve. Simple linear filtering techniques were found to be adequate for producing the trigger signal for the electrical stimulation from the HG recordings. Esophageal pressure, which was used to estimate the size of the UAW passage, returned to the preloading values during closed-loop stimulation of the HG nerve. The data demonstrate the feasibility of the closed-loop stimulation of the HG nerve using its activity as the feedback signal.
