不可否认,受到美国次贷危机的影响,全球经济已经进入持续低迷时期。PC市场首当其冲受到严重影响,各大厂商销量均出现不同程度下滑。鉴于经济形势的严峻,悲观的瑞银分析师甚至下调了苹果、惠普等全球PC公司的股价预期。然而,就在主流PC遭遇市场重挫的时候,曾经一度不被业界看好的上网本(netbook)却逆势飞扬,迅速崛起成为PC市场的新亮点。有人甚至惊呼:这是PC市场的黑马!这个不足12英寸的“小本本”究竟有着什么样的魔力,能够迅速在欧美市场一枝独秀呢?在中国市场它能够行得通吗? 相似文献

现在市场上的上网本种类也不算少了,不过造型普遍像是玩具,塑料感很强甚至有偷工减料的嫌疑。而这款刚发布的华硕EEE PCS 101可以说是上网本中鹤立鸡群的一员。 相似文献

失落和挫折心态在中国IT业具有一定的普遍性。这种挫折心态不仅对IT从业员工造成心理和生理上的损害,而且也在一定程度上降低了我国IT企业的生产效能。从人的需求层次来说,IT人往往处于需求的高层次。大量材料表明,中国IT人的五个层次的需求均存在未被满足状态,有些人则处在极端未满足状态。 相似文献

失 落 和 挫 折 心 态 在 中 国 IT 业 具 有 一 定 的 普 遍 性 。 这 种 挫 折 心 态不 仅 对 IT 从 业 员 工 造 成 心 理 和 生 理 上 的 损 害 ,而 且 也 在 一 定 程 度 上 降低 了 我 国 IT 企 业 的 生 产 效 能 。 从 人 的 需 求 层 次 来 说 ,IT 人 往 往 处 于 需求 的 高 层 次 。 大 量 材 料 表 明 ,中 国 IT 人 的 五 个 层 次 的 需 求 均 存 在 未 被满 足 状 态 ,有 些 人 则 处 在 极 端 未 满 足 状 态 。 相似文献

We confront the following popular views: that mind or life are algorithms; that thinking, or more generally any process other than computation, is computation; that anything other than a working brain can have thoughts; that anything other than a biological organism can be alive; that form and function are independent of matter; that sufficiently accurate simulations are just as genuine as the real things they imitate; and that the Turing test is either a necessary or sufficient or scientific procedure for evaluating whether or not an entity is intelligent. Drawing on the distinction between activities and tasks, and the fundamental scientific principles of ontological lawfulness, epistemological realism, and methodological skepticism, we argue for traditional scientific materialism of the emergentist kind in opposition to the functionalism, behaviourism, tacit idealism, and merely decorative materialism of the artificial intelligence and artificial life communities. 相似文献

As local area networks have developed in response to rapid growth in the distribution of computing power and intelligence, they have found application in a wide range of industrial and commercial areas. This growth has resulted in different definitions and alternative architectures, which can be confusing to the MIS manager attempting to use them. 相似文献

This paper solves an open problem posed by a number of researchers: the construction of a complete calculus for matrix-based methods with rigid E-unification. The use of rigid E-unification and simultaneous rigid E-unification for such methods was proposed by Gallier et al., in 1987. After our proof of the undecidability of simultaneous rigid E-unification in 1995. (Degtyarev and Voronkov, 1996d), it became clear that one should look for more refined techniques to deal with equality in matrix-based methods. In this article, we define a complete proof procedure for first-order logic with equality based on an incomplete but terminating procedure for rigid E-unification. Our approach is applicable to the connection method and the tableau method and is illustrated on the tableau method. 相似文献
