摘要：An innovative design for the treatment and reuse of grey water is presented in the form of a grey water dam which is an outgrowth of the vertical grey water tower. A hydraulic equation has been formulated and is presented in this paper which is used to determine the seepage path within the grey water dam, and determine the dimensions of the dam components. The hydraulic equation model also helps in avoiding soil piping problems by keeping the phreatic line within the grey water dam. Vegetables are planted around the surface of the dam as a reuse option while helping recycling of water in the form of evapotranspiration. A successful pilot trial of this dam was run in Mnyamatsini area in Swaziland which can accept grey water from multiple households.

摘要：在本届戛纳国际创意节中,除了广告界大腕外,还有许多娱乐巨星和名人受广告公司的邀请前来演讲,今年的名单上就包括了Pharrell Williams、Marilyn Mansion和Jamie Oliver等。世界第一音乐鬼才,恶魔摇滚巨星Marilyn Manson向来以十分夸张另类甚至近乎恐怖的妆容造型亮相,黑发,白脸,猩红色的唇妆．这些都令他看上去十分地与众不同。

摘要：可靠性分配是把系统要求的可靠性指标分配给分系统、部件、元件的过程。可靠性分配本质上是一个工程问题，需要考虑的因素都是一些不定因素（尤其是在系统的设计早期阶段），很难用确切的数学语言来描述。即在系统的可靠性方面，我们所获得的各分系统、各部件的有关信息是不完全、不甚确切的。也就是说，这些信息是“灰色”的。本文首先运用灰色系统理论对各分系统进行综合评估，然后在此基础上进行可靠性分配。我们把这种方法称为系统可靠性指标的灰色评估分配法。该方法可以把许估者的分散信息归纳成确切的评估值，较好地解决了在研制的早期阶段，由于对系统的认识不足而带来的问题。

摘要：将直接灰色预测模型引入城市电网年用电量预测中,避开了灰微分方程参数辨识时选取的背景值问题,以模型的还原值与实际值的平均相对误差最小化为优化目标,设计了求解该模型的粒子群优化算法,并与多种预测方法比较。结果表明,该方法合理、有效,预测精度较高。
