面形分割构成论析

本文着重论析了面形分割构成独特的审美性。指出这种构成形式得以成立的关键,是以线分割母面形后,所得五面形必须成为互相依存、牢不可分的,具有符合审美法则的视觉力学关系的整体。提出在作面形分割构成的基本训练中,兼做多种造型表现上的研究与体验的方法。     

Forecasting future canadian residential heating demand: An illustration of forecasting with aggregated and disaggregated data

This paper examines the sensitivity of forecasts to the level of aggregation of the data. A relative shares regression model and a multinominal logit model are tested with both aggregate and disaggregate survey data from 2109 respondents. The results indicate the appropriate model to use depends on whether the data are disaggregate or aggregate in form. Forecasts of solar heating of dwelling unit demand and market shares are also reported for Canada in terms of the solar price relative to the natural gas price and solar reliability relative to natural gas reliability.     

Minimum variance pooling of forecasts at different levels of aggregation

The most common approach to combining forecasts at different levels of aggregation has been to sum (or average) the more disaggregated forecast, and take a weighted average of the aggregate forecasts. This paper develops a simple method for obtaining minimum variance pooled forecasts at the disaggregated level. The major advantage that this method has over the common approach is that it provides pooled forecasts at both the aggregated and disaggregated level. As will be shown, the resulting aggregate pooled forecast is identical to the forecast which would be obtained by simply pooling two forecasts at the aggregate level, while the disaggregated forecast maintains the aggregation identity required by the problem.     

混合金银溶胶-分子体系的表面增强拉曼散射活性研究

通过透射电子显微镜考察了作为表面增强拉曼散射活性基底的混合金银溶胶-碱性品红体系的聚集特性,在银胶、金胶和检测分子共存的条件下,对它们不同的混合顺序会导致体系不同的聚集特性．从而引起表面增强拉曼散射增强效应的变化。跟纯银胶相比,添加了金胶的混合金银胶体系能够有效的增强碱性品红分子的表面增强拉曼散射效应。     

基于自适应遗传算法的传感器网络数据融合算法

能源有效性是无线传感器网络(WSN)路由算法设计要考虑的首要问题,数据融合可以通过合并冗余数据而有效地节约能耗.提出了一种基于自适应遗传算法(AGA)的WSN数据融合算法,基于移动代理(MA)对Sink节点发出兴趣代理报文和目标节点发出数据代理报文进行转发.采用AGA求出MA最优路由节点序列,通过把WSN均匀分割为多个大小适当的二维网格,形成AGA的初始群体.仿真结果表明,随着网络规模增大,和局部最近邻优先算法(LCF)相比,该算法有更小的网络能耗和延时.
