Effects of light and temperature conditions on flowering in Mat Rush     

沈伟其  张国平  奚利峰  桂文光 《浙江大学学报(A卷英文版)》2002,3(5):611-616

The effects of photoperiod and light intensity on flowering in Mat Rush cv. Gangshan 3 were studied. The results showed that treatments with longer day length stimulated flowering significantly and increased stem flowering percentage (SFP). Plants treated with low light intensity at early stage had substantially reduced florets per cyme, SFP, tillers per plant and stem length. At middle and late stage, low light intensity significantly reduced SFP. The principal climatic factors affecting SFP were as follows: mean temperatures (MT) of the third ten-day period (TDP) in December and of the second TDP in February, actual sunlight hours (SH) of the third TDP in February and precipitation of the third TDP in March. A nonlinear simulation model for SFP was established with experimental results and corresponding climatic data (see Eq. (2)). Simulation by the above equation yielded values the same as those observed from 1992 to 2000, indicating its accuracy in describing the relationship between flowering and light and temperature conditions. The interaction between vernalization and SH is also discussed in this paper. Project (No. 981105) supported by the Ningbo City Science Foundation, China  相似文献

基于HLA的分布式入侵检测系统仿真设计     

屈长青 《湖南科技学院学报》2007,28(4):34-36

分布式入侵检测系统（DIDS）是一种分布于网络环境的入侵检测系统,随着网络环境的日益复杂化,DIDS的设计任务也日趋繁重,对系统的仿真是其规划和设计的首要任务。高层体系结构（HLA）是当今世界上非常流行的分布式仿真技术之一,它建立了一个通用的仿真技术框架。基于HLA的仿真应用系统的设计,已经成为当前的研究热点。分析了HLA和DIDS的基本框架,以HLA为基础,借用相关辅助设计软件,对分布式入侵检测系统进行了仿真设计。通过仿真,较好地解决了分布式入侵检测系统的规划和设计方案的复杂性问题,为进一步的实际开发和应用提供了可靠的依据。  相似文献

Discovering the Laws of Sampling     

Keith Rennolls  Michael Massay 《Teaching Statistics》1991,13(3):71-73

That the sample mean and variance are “good” estimates of the corresponding population parameters is easily accepted as “obvious” by students, but the concept of standard error of the mean is often found to be quite a hurdle. That this standard error decreases inversely as the square-root of the sample size, and the mysterious appearance of the Normal distribution, are often taken as magical and incomprehensible effects, and non-mathematical students can often be turned away from further understanding. This article describes a program which provides an experimental framework in which the student can rapidly develop an intuition for the basic properties of sampling.  相似文献

The effectiveness of workflow management systems: A longitudinal study     

《International Journal of Information Management》2016,36(1):126-141

Workflow management systems coordinate and allocate work through the various stages of executing business processes. The benefits of such systems appear pervasive, but no hard data is available that confirms that their implementation improves organizational performance. In part, this is due to the difficulty of measuring the effects of enterprise-wide initiatives in general. In this paper, the results are presented of a longitudinal, multi-case study into the effectiveness of workflow management technology. The study builds on a novel methodology that combines field work and computer simulations. Through its application, the contribution of this technology to conduct business processes faster and with less effort could be quantitatively assessed. Surprisingly, only a fraction of the projects that were followed in this longitudinal study led to a fully operational implementation of a workflow management system at all. Even so, in most of the projects where such a system was introduced this resulted in substantial improvements. We present success and fail factors for the implementation of this technology within organizations, which we inferred from a follow-up analysis. The novel methodology presented in this paper is thought to be of value to track the performance effects of introducing other technologies or organization concepts as well.  相似文献
