摘要：Public housing （PH） has existed in Hong Kong for six decades. Previous and current challenges that have been encountered over time function as a coffective driver for design progression. However, such challenges have remained under research to be able to draw useful lessons from them. To understand how this established motif can suit the sustainability-conscious era, this study uses Hong Kong as a representative case for sub-tropical compact cities by critiquing its PH design against multiple constraints. The objective of this study is to trace the historical relationships between challenges and design progress as well as to assess current and future implications of sustainability trends on PH design. By synthesizing data from literature, policy documents, and empirical evidence, this research develops an evolution map for PH design in Hong Kong that is driven by seven major challenges. Based on this map, a conceptual framework for intersecting considerations that envisaaes five main future prospects toward future PH desien is also established.

摘要：Drawing on resource dependence theory, this paper develops and empirically tests a model for understanding how the implementation of building information modeling(BIM) in construction projects impacts the performance of different project participating organizations through improving their interorganizational collaboration capabilities. Based on two sets of survey data collected from designers and general contractors in BIMbased construction projects in China, the results from partial least squares analysis and bootstrapping mediation test provide clear evidence that BIM-enabled capabilities of information sharing and collaborative decision-making as a whole play a significant role in determining BIMenabled efficiency and effectiveness benefits for both designers and general contractors. The results further reveal that designers and general contractors benefit from project BIM implementation activities significantly nonequivalently, and that this non-equivalence closely relates to the different roles played by designers and general contractors in BIM-enabled interorganizational resource exchange processes. The findings validate the resource dependence theory perspective of BIM as a boundary spanning tool to manage interorganizational resource dependence in construction projects, and contribute todeepened understandings of how and why project participating organizations benefit differently from the implementation of interorganizational information technologies like BIM.

摘要：固体氧化物电池将在未来可再生能源储存转换系统中占据重要位置.但SOCs受制于低耐久度的影响,目前仍需在新材料开发和工程设计方面取得进一步的突破以实现商业化.这项研究报道了一个数据驱动的粉体-能量框架(Powder-to-power framework,P2PF),通过实现从制备到长时运行的异质电极形貌演化数字化,实现了对于整个生命周期的性能预测.首先通过参数分析阐明了微结构参数对于燃料电极长期性能的内在影响机制,发现合理控制离子导电相的体积分数不仅可以有效抑制镍粗化,还是减少镍迁移引起的欧姆损失增加的关键.电极初始性能和性能衰减率是多参数耦合作用的结果.所构建代理模型被应用于多目标遗传算法以提出简单可行的耐久度优化策略.数据驱动的粉体-能量框架确定了满足不同最大运行时长要求的最佳电极制备参数,并将镍基电极的降解率从基本工况下2.132%kh^(-1)降低到0.703%kh^(-1)(最大运行时长大于50000 h).
