测控设备采用传输控制协议/网际协议(TCP/IP)作为基础协议,进行遥控多通道并行工作时易造成网络数据粘包。针对此问题,在对TCP协议特点进行分析的基础上,通过讨论TCP编程模型和流交付模型,研究了发生TCP数据流粘包时的网络数据特征,并分析了发生网络粘包的原因,提出了局域网环境下采用短连接、发送端及格式数据组包3种解决网络粘包的方法。实际测试结果证明了这3种方法的适应性及格式数据方法还原TCP网络数据包的有效性,可为基于TCP应用软件开发提供借鉴。 相似文献

Green Lean Six Sigma has been recently clarified to improve the environmental sustainability performance of operations, but it seems glaringly scarce and in need of cutting-edge studies to integrate the concepts of green, lean, and Six Sigma into one unified application. This paper is accordingly aimed at constituting the application of Green Lean Six Sigma as a cleaner production. In doing so, a Define, Measure, Analyze, Improve, and Control (DMAIC)-based approach that is one of Six Sigma's well-known methods was proposed to systematize a Green Lean tool—environmental value stream mapping. Thus, this paper as one of the preliminary studies aligns environmental value stream mapping with DMAIC through presenting the proposed methodological approach, which relies on the five DMAIC phases—Define, Measure, Analyze, Improve, and Control—and considers green wastes in each phase simultaneously. To support the narrow body of knowledge, this proposed approach was validated via the action research-oriented case study implemented in the substrate manufacturing system that seeks to develop the environmental sustainability of its production processes and subsequently its general competitiveness. The findings indicated the effectiveness of a DMAIC-based approach in systematizing environmental value stream mapping and improving its efficacy to achieve environmental sustainability. The case analysis revealed that the application can significantly lessen the consumption of chemicals and energy in the system by 28% and 21%, respectively. 相似文献

以需求理论为基础,构建了影响张家界旅游客流波动的计量经济学模型来分析其旅游客流波动的主要影响因素,并评价各因素发生变化时对其旅游市场需求产生的影响。通过实证研究得到的基本结论是:影响张家界旅游客流波动的主要因素是宏观政治经济环境,游客在张家界旅游的成本,游客本身的经济条件,与张家界相竞争的旅游目的地旅游价格水平和旅游者“自我宣传效应、旅游持续性行为”等。 相似文献

TAX BASIS AND NONLINEARITY IN CASH STREAM VALUATION 总被引:2,自引:0,他引:2
The value of a future cash stream is often taken to be its net present value with respect to some term structure. This means that a linear formula is used in which each future payment is discounted by a factor deemed appropriate for the date on which the payment will be made. In a money market with taxes and shorting costs, however, there is no theoretical support for the existence of a universal term structure for this purpose. What is worse, reliance on linear formulas can be seriously inaccurate relative to true worth and can lead to paradoxes of disequilibrium. A consistent no-arbitrage theory of valuation in such a market requires instead that taxed and untaxed investors be grouped in separate classes with different valuation operators. Such operators are linear to scale but nonlinear with respect to addition. Here it is established that although these valuation operators provide general bounds applicable across an entire class, individual investors within a tax class can have more special operators because of the influence of existing holdings. These customized valuation operators have the feature of not even being linear to scale. In consequence of this nonlinearity, investors from the same or different tax classes can undertake advantageous trades even when the market is in a no-arbitrage state, but such trade opportunities are limited. Some degree of activity in financial markets can thereby be understood without appeal to differences in utility functions or temporary disequilibrium due to random disturbances. 相似文献

言语是人们进行交际活动的过程或产物。人们在用言语进行交际活动过程中,言语 通常带着一定个体主观反映和表述客观现实的印记,即具有个体性和多变性。它往往不会偏离该 语言的标准发音规则和语法规则,而且在同一情景下,在描述或表达同一事件时,会因个体的知 识水平、生活经历、职业、地位、观点、情绪等不同显示出言语表述方式和表现风格上的差异。 英语言语的这种个体性、多变性现象是影响中国学生英语听力理解的主要因素之一。加深对英语 言语个体性和多变性的表现规律的认识,有助于提高听觉感知、理解英语的能力。 相似文献
