相变储能建筑材料的应用研究

随着人们对工作与居住环境要求的提高以及环保意识的增强,对建筑材料的要求也日益提高,多功能化、智能化已成为建筑材料发展的必然趋势。相变储能建筑材料就是为满足这种要求而开发的,它是相变材料与建材基体复合制备的一种新型储能建筑材料,具有储能密度大、效率高以及近似恒定温度下吸热与放热等优点,可用于储能和温度控制。本文主要介绍了相变储能建筑材料的特点、研究现状以及形成工艺等,并对其发展进行了展望。     

CT代数重建算法的快速实现

代数重建算法比解析重建算法在重建图像质量上有很大优势,但代数重建算法计算量较大,因而使其在实际应用中受到许多限制.针对代数重建算法中系数矩阵计算占绝大部分重建时间的情况,提出了一种将系数矩阵预先计算,并将系数矩阵计算结果存储于硬盘的方法.该方法大大提高了代数重建算法速度,并能够使用计算复杂的精确投影系数矩阵,从而可提高...     

基于新扫描策略的快速立体匹配算法

为提高立体匹配的运算速度,提出一种新的图像匹配扫描策略改进传统算法。在匹配扫描过程中,将图像由左至右的三列作为一组,各组内除首行外扫描次序为中间列、左列、右列像素点,按照文中扫描策略及像素点,在图像中所处位置,分别给出了各种情况下,以较小的存储空间,利用水平和竖直方向相邻像素点的模板已计算值,减少算法执行时间的方法。通...     

煤矿矿井地质工作的探究

煤矿整个地质工作从矿井建设开始到开采结束,每一个环节都是紧密相连的,在这一个过程中要掌握整个矿井,甚至是整个煤田的构造发育变化规律、煤层的赋存状态、标志层和煤层的层间距及其岩性特征。在这一个过程中的矿井地质工作,是通过做到:1看2对3描4整改5总结的工作流程,这个工作流程同样适用于井下每一次地质变化时的工作。

Conditions for aggregation of CHP plants in the UK electricity market and exploration of plant size

Combined heat and power (CHP) plants with thermal stores may be suitable for sustainable energy production and the accommodation of fluctuating renewable energy sources. At the moment, in the UK, only a few CHP plants have thermal stores. Previous research has shown that thermal stores can improve the economics of CHP plants in the UK under the current market conditions. However, currently, it is only beneficial for CHP plants to sell their electricity to a third party, a Licensed Electricity Supplier, rather than to sell it directly to the power exchange market at prices which are much higher. If CHP plants aggregate, direct access to the power exchange market can become economically viable hence there is the possibility that thermal stores could further improve the economics of CHP plants under an aggregated electricity dispatch. This work firstly explains the conditions under which such plants could aggregate and act as a large power plant in the UK market, and secondly explores the most economic-size of gas engine and thermal store, in the case of aggregation, using energyPRO software and Excel spreadsheets. The work suggests that direct access to the power exchange market can improve the economics of the CHP plants. The highest Net Present Value (NPV), without heat dissipation, for a CHP plant exporting its electricity to the grid for a community heating load of 20 GW h, is more than £5 m, and is obtained for a 6 MW engine with a 28.2 MW h (900 m³) thermal store. The research suggests that such high electricity prices could make even larger plants more profitable than that; however, this can happen only if some of the produced heat is dissipated.     

Store manager performance and satisfaction: Effects on store employee performance and satisfaction, store customer satisfaction, and store customer spending growth.

Based on emotional contagion theory and the value–profit chain literatures, the present study posits a number of hypotheses that show how managers in the small store, small number of employees retail context may affect store employees, customers, and potentially store performance. With data from 306 store managers, 1,615 store customer-contact employees, and 57,656 customers of a single retail chain, the authors examined relationships among store manager job satisfaction and job performance, store customer-contact employee job satisfaction and job performance, customer satisfaction with the retailer, and a customer-spending-based store performance metric (customer spending growth over a 2-year period). Via path analysis, several hypothesized direct and interaction relations among these constructs are supported. The results suggest implications for academic researchers and retail managers.
