为优化B/S系统结构与网络数据负载,本文在HTML5的WebStorage和WebSocket技术基础上,设计了一种异步数据传输方案。它将部分业务逻辑移交到客户端执行,并在客户端本地缓存数据,以异步方式与服务器进行交互。实践证明能有效减轻服务器负担,增强用户体验。 相似文献

从技术角度讲,在电子刊物出版时,通常认为必须从彼此竞争的两种技术——SGML(通用标准标记语言)和PDF(可移植文档格式)中选择一种,然而事实并非如此。本文从SGML(XML和HTML)与PDF的格式入手,对比分析了两者间的异同,阐述了他们在应用上并没有本质的冲突。最后提出了他们在电子出版领域中结合使用的一种方案。 相似文献

本文提出了一种高速Turbo编译码方法。从算法改进和结构改进技术两方面进行研究,以期解决现有译码算法难以实现高速这一问题。在结构改进技术方面,采用分块思想,将分量编码器分成两块并行处理,速度提高一倍;在算法改进技术方面,一方面针对目前存在的复杂度较低、性能次优的Radix-4 Max-Log-MAP译码算法,通过尺度因子的补偿,得到了译码性能较好的SF-Max-Log-MAP算法。另一方面采用了HDA停止迭代准则,有效地减少了译码时延。 相似文献

Until now, it has been thought that the best way to improve quality was to improve yield, that is, to improve the manufacturing process so that fewer defective parts are manufactured. This philosophy has been applied to all areas of manufacturing, from widgets to whalers. One of the tenets of this philosophy is that quality should not be tested in, but should be built in via a well-controlled process that is continuously improving. However, when it comes to semiconductors, significant improvements for a process in order to improve yields can cost millions of dollars. In such a capital intensive industry, where the life of a process is only a few years, such investments are often not in the best economic interests of a semiconductor manufacturer. How, then, can the customers' requirements for quality be met? This article shows that for typical values of yield and test coverage, quality improves faster due to improvements in test coverage than it does for improvements in yield. As a result, testing can be used to achieve improvements in quality at lower costs, and therefore more economically, than improvements in the manufacturing process. 相似文献

The time slot assignment algorithm presented in the above paper needs certain improvements for it to be an efficient one. In this correspondence, the necessary improvements are incorporated and an improved SS/TDMA time slot assignment algorithm is presented. The new algorithm is compared to the old one and the computer simulation exhibits a better performance of the present algorithm. 相似文献

The Avionics Logistics Effects (ALE) model was developed in 1973 in response to a US Navy requirement to evaluate potential benefits of reliability and maintainability improvements that might be incorporated into the AWG-9 weapon control system on the F-14 aircraft and AWM-23 ground support equipment. The model simulates the entire F-14 aircraft (avionics and non-avionics) in terms of squadron flight operations, maintenance, and support aboard an aircraft carrier. Its major application is to determine the impact of avionics system design and maintenance changes on aircraft availability. Several studies have been performed with the ALE model, and one in particular is discussed in this paper. In this case, Hughes recommended 27 separate reliability and maintainability improvements to the AWG-9/AWM-23 systems. The contribution of these improvements to F-14 availability is discussed, with particular emphasis on achieved crisis-flight rate. 相似文献

Minority carrier lifetimes in semiconductor diodes can be measured by suddenly terminating forward diode current and observing the consequent decay of diode voltage. While this open circuit voltage decay (OCVD) method is very simple in principle, departures of the observed decay curves from the predicted linear relationship cause the method to be subjective and unreliable in practice. This paper describes simple improvements to this method which largely overcome these difficulties. These improvements are based on the passive differentiation of the open circuit decay curve and compensation for the effects causing departures of this curve from linearity. 相似文献
