青岛高校用水与节水现状调查与模式研究

在分析我国高等学校用水与节水特点的基础上,就青岛市8所高校的节水器具和节水措施进行了调查分析,结果显示:节水器具在各高校有不同程度的应用,但在节水硬件和用水管理上仍存在着水资源浪费的现象;高校人均用水量为居民人均的2倍;民办高校比公办高校具有较好的节水意识。针对调查结果,提出了推广廉价节水的陶瓷阀芯及其他新型水龙头,推广小便器和蹲式便槽,在新建浴室采用具有循环系统的单管恒温供水,实行阶梯水价收费制度,及对高校内中水和雨水资源合理利用的技术和管理模式,为“节约型”校园建设提供了新思路。     

济南市某建筑小区污水再生回用工程设计

为节约水资源，实现水资源的可持续利用，济南市新开发的某建筑小区拟建设污水再生回用工程。该工程处理规模为5000m^3／d。进水为生活污水，出水要求回用于冲厕、绿化、浇洒道路和水景用水等。设计中通过多个处理方案经济、技术方面的比较，采用了CASS工艺。同时介绍了该工艺主要构筑物和设备的设计参数，最后进行了工程投资分析。     

嵌入式多媒体应用中的片上存储器分配

为了提高嵌入式多媒体应用的运行速度并降低功耗,本文提出一种高效利用片上存储器的方法.将数据矩阵划分成合理大小的子块,分阶段地将数据子块转移到片上,并尽可能重复利用已经转移到片上的数据,以便有效地减少片外存储器与片上存储器之间的数据转移.通过对汇编语言中存储器阵操作数适当分配,避免读写数据延迟.根据汇编语言代码写出不产生流水线停滞的各个矩阵操作数的存储器位置限制条件,根据限制条件,本文提出求解矩阵分配的方法.

LP-based solution strategies for the optimal design of industrial water networks with multiple contaminants

This paper presents a new approach for the optimal design of water-using networks. Starting with a superstructure that accounts for all possible connections between water sources and water-using operations, different substructures are generated that consider all possible sequences of operations. Then, each operation is tackled one at a time, from the first to the last element in the sequence. This procedure has the advantage of replacing a nonlinear program (NLP) by a succession of linear programs (LP) that are solved for all operation sequences. Although part of the feasible region is lost in the process, the results have shown that the optimal solution is often obtained. The new procedure is at the same time a good approach of generating structurally different solutions that can be used as starting points for the full NLP. By doing this, local solutions can be avoided and the probability of finding the global optimal solution to the problem is increased. When compared to the standard initialization procedure that features a single starting point, the new approach is more efficient but substantially more demanding computationally. A trade-off can be reached by using the standard technique with multiple starting points originated from the possible operation sequences.     

Strategic assessment of building adaptive reuse opportunities in Hong Kong

There is an increasing complexity and interplay between all the issues associated with property portfolio decisions. This paper explores the relationships between financial, environmental and social parameters associated with building adaptive reuse. An adaptive reuse potential (ARP) model is developed and discussed in the context of its application to the Hong Kong market. The model can assist in the transformation of the traditional decision-making processes of property stakeholders towards more sustainable practices, strategies and outcomes, by providing a means by which the industry can identify and rank existing buildings that have high potential for adaptive reuse. This in turn enhances Hong Kong's ability for sustainable, responsive energy and natural resource management by allowing issues regarding excessive and inappropriate resource use to be identified and assessed, and enabling appropriate management strategies to be implemented. The ARP model proposed in this paper provides, illustrated by a real case study, an important step in making better use of the facilities we already have and the residual life embedded in them.

复杂立方体聚集依赖及其查询技术

针对复杂立方体查询中可能存在的3种聚集依赖(完全依赖、部分依赖和互斥依赖),分别提出了3种基于Cache重用技术的解决方法:完全Cache重用、部分Cache重用以及反Cache重用机制,并相应地给出了计算方法和算法.在模拟和真实数据集上的实验结果表明,不同数据集下改进算法均比基本算法的效率有明显提高,特别地,数据量越大,Cache重用技术的优越性越明显.
