Sometimes factors-such as government regulations, personal preferences, or even national pride-can intervene to preserve an outmoded technology long after technical considerations would dictate its demise. The town of Orleans, nestled in the elbow of Cape Cod, Massachusetts, harbors one such product of benign neglect: the French Cable Station Museum. This article describes the history of the telegraph-cable connections between France and the Cape, dating back to 1879, only thirteen years after the first permanently successful transatlantic cable was laid. French patriotism influenced the routing and operation of the cables as much as economics or engineering. The submarine telegraph cable was an interesting propagation medium in its own right. Even after intercontinental radio communications became practical, some of the best minds in the communications industry applied themselves to the problem of maximizing cable-transmission rates, with mixed results. I review two significant technical advances in submarine-cable technology that occurred between 1900 and 1930. Finally, I conduct an armchair tour of the French Cable Station Museum as it is today, one of the few communications museums in the country which preserves historic operating equipment at its original site 相似文献

A standard contract (one printed on a standard form, with standard language) can be changed or fully rewritten to meet your company's specific needs. Buying equipment without a contract that meets your company's specific needs and that is drafted or reviewed by legal counsel (specifically a lawyer who knows your company's needs well) is the equivalent of buying a potential lawsuit. Prevention of problems with a good contract and legal help is your company's best insurance against waste and/or litigation. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

老祖宗的话说得的确有道理:一年之计在于春,当我们还沉浸在CES2007(每年最早的一次IT展会)上的新奇玩意儿时,苹果公司却在2007年度Mac World大会上带给我们远比它更令人瞩目的消息:iPhone现身!
不用担心,这不是这两年来的任何一次谣言,iPhone真实存在,苹果公司首席执行官司史蒂夫·乔布斯在宣布这个消息并试玩时,还“顺带”好心为各位苹果迷们准备了两个真机以供参观——真机被放置在透明柜台中,接受着它的推崇者顶礼膜拜的目光和来自竞争对手的可杀死它几万次的目光。[编者按] 相似文献

Not in recent times has so much of the engineering force been on the unemployment rolls. Job seeking is never easy, and for many engineers the experience may be novel. This article covers the steps that the engineer job seeker should follow initially, and cites some of the dos and don'ts to help him sell himself. 相似文献
