Investigation of the impact of changes in demand forecasting method on the financial performance of an electricity supply undertaking

Peak demand forecasts obtained from six different univariate forecasting methods, under a range of conditions, were used to drive a capacity acquisition model of a large electrical supply system; and the resulting physical and financial performance of the model was observed for each set of forecasts. The results obtained are discussed in the context of their implications for the choice of load forecasting method used in capacity acquisition planning by a power supply undertaking.

Life cycle cost analysis of alternative vehicles and fuels in Thailand

High crude oil prices and pollution problems have drawn attention to alternative vehicle technologies and fuels for the transportation sector. The question is: What are the benefits/costs of these technologies for society? To answer this question in a quantitative way, a web-based model (http://vehiclesandfuels.memebot.com) has been developed to calculate the societal life cycle costs, the consumer life cycle costs and the tax for different vehicle technologies. By comparing these costs it is possible to draw conclusions about the social benefit and the related tax structure. The model should help to guide decisions toward optimality, which refers to maximum social benefit. The model was applied to the case of Thailand. The life cycle cost of 13 different alternative vehicle technologies in Thailand have been calculated and the tax structure analyzed.     

电潜泵大修打捞配套工具研制

随着采液时间的延长,电潜泵井事故不断增加,仅辽河油田每年就有30口左右的电泵井需要转大修.由于没有专用的打捞工具,作业设备的能力有限,其处理事故的周期往往较长,效果不理想.因此,在已有φ139.7mm套管内电泵打捞工具的基础上,研制开发了φ177.8 mm套管内电泵打捞工具,解决了油田电泵打捞的难题.     

DCOP FOR SMART HOMES: A CASE STUDY

The aim of this article is to bring forth the issue of integrating the services provided by intelligent artifacts in Ambient Intelligence applications. Specifically, we propose a Distributed Constraint Optimization procedure for achieving a functional integration of intelligent artifacts in a smart home. To this end, we employ Adopt-N , a state-of-the-art algorithm for solving Distributed Constraint Optimization Problems (DCOP). This article attempts to state the smart home coordination problem in general terms, and provides the details of a DCOP-based approach by describing a case study taken from the RoboCare project. More specifically, we show how (1) DCOP is a convenient metaphor for casting smart home coordination problems, and (2) the specific features which distinguish Adopt-N from other algorithms for DCOP represent a strong asset in the smart home domain.     

RMT1-250转换开关用电接触材料

铜铬锆合金是一种形变热处理材料，兼具了铜铬合金和铜锆合金的各种优良性能，经过时效处理的铜铬锆合金，与铜相比，高温强度有很大的改善，而且具有较高的导电率。所以铜铬锆合金广泛应用于电焊机、低压电器等行业。根据对铜铬锆成分的适当调整，可用作为电焊机电极，低压电器触桥、短路环等各种电接触材料。铜铬锆合金用于RMT1－250转换开关，接近于触桥材料的应用，但使用的条件更苛刻一些，要承受部分电弧的侵蚀和由此产生的高温，因此对材料要求具有良好的导电导热性和更高的高温强度。
