基于老厂房改造的景观规划设计

随着城市化高速发展，老厂房再利用的问题日益急迫.上海是中国近代工业起源地,也是率先着手对彰显城市文脉的工业遗产进行调查和保护的历史文化名城.本文以上海典型案例入手，分析了具有代表性的老厂房改造的项目特点，并在此基础上，对常州大成三厂这一民国时期的纺织业遗留地块进行改造设计手法进行介绍，从设计理念、设计内容和节点设计3个方面，体现了文化传承和生态技术相融合理念.     

城市治理首要应加强市民的思想道德建设——以湛江市治理交通秩序为例

交通混乱既影响城市形象,又制约经济发展。本文通过对湛江市区交通混乱现象进行深入调查研究,认为要从根本上改变这一现状,取得长效成果,除了采取行政立法、经济处罚、改善交通基础设施等治理措施外,还应着重加强市民的道德建设,提高其思想道德素质,培养市民良好的社会道德行为习惯。文章旨在为加强湛江市民道德建设,解决湛江及其它城市突出交通问题提供参考。

“二三结合”开发模式渗流特征研究

L油田B区块开展"二三结合"实验区,"二三结合"开发模式渗流特征对区块的合理高效开发具有重要意义。为了明确其渗流特征,利用油藏数值模拟软件Eclipse建立代表意义的油藏数值模型,研究区块"二三结合"开发模式下原射孔层和补孔层的渗流特征,分析了"二三结合"开发模式下,不同开发阶段综合含水率、采出程度、井底压力、地层压力及含水饱和度的变化特征。研究表明,"二三结合"开发模式先通过水驱开发挖潜原射孔层剩余油,提高厚油层顶部剩余油的采出程度,再通过聚合物驱进一步提高开发效果,通过水驱与聚驱的综合作用,最终得到较好的开发效果。

彩虹黑弦的热力学性质

双重相对论(DSR)是描述平直时空中的量子引力的一个有效模型.当试图将该模型纳入到弯曲时空中考虑时,一种被称为"彩虹引力"的理论可帮助实现这一推广,此时背景时空依赖于探测粒子的能量.事实上受粒子能量影响的度规的形式依赖于正交系的选取.本文主要考虑了自由落体参考系下的彩虹静态柱对称黑洞(彩虹黑弦).得到了取一阶近似的彩虹黑弦的霍金温度和熵,这种修正来源于考虑的彩虹引力效应.     

基于修正斜压场的RC框架边节点剪切性能分析

为研究钢筋屈服强度和混凝土抗压强度对钢筋混凝土(RC)框架边节点剪切性能的影响规律,基于修正斜压场理论(MCFT),对某框架边节点的剪切应力-应变骨架曲线进行数值模拟,并与试验结果进行对比.在验证MCFT算法的精度后,研究钢筋屈服强度和混凝土抗压强度两个参数变化对RC框架边节点剪切应力-应变骨架曲线和峰值剪切应力的影响规律.结果表明:基于MCFT可以较好地模拟RC框架边节点的剪切应力-应变关系曲线; RC框架边节点的峰值剪切应力对混凝土抗压强度的变化更为敏感,但当试件的钢筋(HRB400)屈服应力下降幅度超过16.45%时,对钢筋屈服应力的变化更为敏感;当试件的钢筋(HRB400)屈服应力下降幅度超过10%时,节点发生钢筋滑移破坏,此时峰值剪切应力会大幅下降.     

Study on the Centralization Strategy of the Blood Allocation Among Different Departments within a Hospital

By far, the researches on how to distribute blood products among different departments in hospital have not been further studied, though the problem of blood shortage and wastage that caused by improper blood allocation is severe, which may endanger patient’s lives and impose considerable costs on hospitals. In order to solve this problem, this paper mainly studies on how to distribute the blood items among different departments within a hospital and investigates the allocation approach with the novel management method by centralizing the inventory of several different departments. By integrating the blood inventory requirements of some departments, the hospital could reduce the rate of blood shortage and wastage effectively, release the pressure of the occupancy of resources and reduce the bullwhip effect of blood products. This paper illustrates the centralization principle in hospital and formulates the mixed integer programming model to work out the optimal allocation network scheme and the optimal inventory setting for every department. And the results of the numerical example demonstrate that this centralization method could considerably reduce blood shortage and wastage in hospital by about 72% and 90% respectively. Furthermore, it could decrease the total cost by about 108,540 RMB a month on blood supply chain management in the hospital and improve the effect of some certain surgeries by transfusing the fresh blood to patients.     

Fuzzy Views on Black-Litterman Portfolio Selection Model

In this paper, views of investor are described in fuzzy sets, and two fuzzy Black-Litterman models are constructed with fuzzy views and fuzzy random views respectively. In the models, expected returns and uncertainty matrix of views are redefined and the views are formulated by fuzzy approaches suitably. Then the models are tested with data from Chinese financial markets. Empirical results show that the fuzzy random views model performs the best, and both the fuzzy models are better than the traditional ones, demonstrating that the fuzzy approaches can contain more information in the views and measure the uncertainty more correctly.
