Restructuring the Russian electricity sector: Re-creating California?

The Russian Federation has begun restructuring its electricity sector, following the standard restructuring model of complete vertical separation of generation from transmission, with the aim of creating competition in regional generation markets. This paper examines the structure of the six principal regional generation markets that are in their early stages of development and argues that they are likely to be characterized by high levels of market power on the part of individual privatized generation companies, especially during the peak winter demand season. These levels—considerably higher than those that caused competitive problems in California—seem to create a serious risk of price spikes in deregulated wholesale electricity markets, and thus of significant price increases to consumers of electricity.

Testing equality of inverse Gaussian means under heterogeneity, based on generalized test variable

The inverse Gaussian (IG) distribution is an ideal candidate for modelling positive, right-skewed data due to the fact that its inference theory and methodology bear a striking resemblance to the normal theory and methods. For testing equality of several IG means under the assumption of equal scale parameters, there exists the ANORE (analysis of reciprocal) F test, which is analogous to the ANOVA F test for the normal distribution. In this article, the concept of generalized P-value, introduced by Tsui and Weerahandi [1989. Generalized P-values in significance testing of hypotheses in the presence of nuisance parameters. J. Amer. Statist. Assoc. 84, 602-607], is applied for testing equality of several IG means for the general cases without the assumption of homogeneity. Simulation results indicate that the proposed test has excellent type I error control under both heterogeneity and homogeneity, whereas the type I error probabilities of the ANORE test can be much larger than the nominal level under heterogeneity. The proposed procedure is illustrated using two examples.     

基于win98的气辅注气实时控制方案

本文针对气体辅助注塑成型注气控制这样一个实时性要求较高的计算机控制系统，分析了控制系统的任务要求。通过分析基于win98平台进行实进控制的技术限制，指出采用win98的定时器不能满足实时控制要求，并提出了实现高精度实时控制的几种方案。通过对这几种方案的分析比较，并根据实际情况，确定在本注气控制系统中采用WINDOWS系统的多媒体扩展库所提供的多媒体定时函数来实现实时控制要求。本文介绍了使用该函数编写控制软件应注意的问题。该控制系统在气体辅助注塑成型注气控制系统上能可靠运行并达到了预期目标。
