虽然国内多功能一体机市场的规模不断增大,但与复印机、打印机、扫描仪的市场相比,还是小很多。像富士施乐这样的厂商,在多功能一体机市场的增长还是要凭借其本身在OA方面的影响力,因此富士施乐的多功能一体机具有更多的OA办公设备的特点。 IT厂商是从打印机、扫描仪着手进军多功能一体机市场的。而OA厂商是从复印机、传真机着手进军多功能一体机市场的,这就注定了两大阵营对多功能一体机发展方向的分歧。鉴于多功能产品在不同公司中的地位,OA及IT厂商为其定义了两种发展方向并采取了不同的销售模式。为了不影响打印机、扫描仪在IT市场中的主流地位及市场份额,IT厂商对多功能一体机的定义是一种补充型产品;由于多功能一体机在性能、品质上 相似文献

把铅笔和橡皮合在一起,变成带橡皮头的铅笔,这曾经是当时最值钱的专利之一。把传真机、复印机、打印机、扫描仪合在一起,变成多功能一体机,它会再现橡皮头铅笔的风采吗? 多功能一体机是从四个原型机发展而来的,而富士施乐由于自身传统的优势,以复印和传真为主要功能来拓展 相似文献

Hyperbolic regression analysis is an effective method for fitting experimental data points obtained from a variety of experiments in molecular biology, including enzyme kinetics, agarose gel electrophoresis of DNA fragments, SDS-polyacrylamide gel electrophoresis of proteins, enzyme-linked immunosorbent assays (ELISA), radioimmunoassays (RIA), Bradford protein quantitation assays, Lowry protein assays, and other applications. Hyperbolic regression yields excellent fitted curves without the biases that are introduced by carrying out linear regression on double reciprocal coordinates, and it produces one simple equation, encompassing all the data points, that can be used easily in a pocket calculator to estimate the values of unknown samples from the known standards. 相似文献

Aspect-oriented programming (AOP) is a novel programming paradigm that aims at modularizing complex software. It embraces
several mechanisms including (1) pointcuts and advice as well as (2) refinements and collaborations. Though all these mechanisms
deal with crosscutting concerns, i.e., a special class of design and implementation problems that challenge traditional programming
paradigms, they do so in different ways. In this article we explore their relationship and their impact on modularity, which
is an important prerequisite for reliable and maintainable software. Our exploration helps researchers and practitioners to
understand their differences and exposes which mechanism is best used for which problem. 相似文献

Intrinsic magic calculation exploits constraints arising from physical and imaging processes to derive physical scene parameters from input images. After a brief review of a paradigmatic intrinsic image calculation we turn to a recent result in shape from texture and then to a new result that derives shape and motion from a sequence of patterned inputs. Experimental results are demonstrated for synthetic and natural images. 相似文献

针对细胞培养箱温度控制具有非线性、时滞性、易受干扰且难以建立精确的数学模型的特点,传统的PID控制方法对于快速维持系统箱内温度稳定存在一定的局限性。提出了以温度误差和误差变化率为控制输入,培养箱内温度为控制量的模糊PID参数自整定的温度控制算法,实现了对PID参数的实时在线修正。实验表明,该模糊PID参数自整定温度控制算法,温度从26℃上升到目标温度37℃,建立稳态的时间为2890s,温度超调极小。系统温度控制精度为±0.05℃,并在相同型号的细胞培养箱上同样得到验证。在控制稳定性方面获得了比传统PID控制更好的控温效果,稳定快,极小超调,温度控制精度高,能满足细胞培养箱温度控制的要求。 相似文献
