无线传感器网络基于置信因子的数据分发机制

无线传感器网络中节点的能量大部分用来传输数据,为减少数据的传输量,同时不增加数据包的延迟,提出了基于置信因子的数据分发概念。由于置信因子由传感器节点根据所感知的数据产生,反映了数据的真实性和重要性,由于设计了一种基于置信因子的发送退避策略和传输过滤器,解决了保证重要数据的优先信道访问权和减少冗余数据传输量的问题。大量仿真证明,这种数据分发机制在减少网络能耗和重要数据的时延方面是有效性的。     

三门峡西段村水库泄洪洞—消力池部位黄土岸坡稳定性分析

西段村水库位于黄河支流的涧河上,大坝右岸消力池部位黄土岸坡施工过程中出现失稳变形现象,致使消力池施工被迫停止。为保证安全,需对消力池及上游右坝肩至泄洪洞出口段黄土边坡进行稳定性评价,为此,开展了必要的地质研究工作,并应用计算软件进行了分析计算,提出了针对性的处理措施。本研究成果在工程中的应用,解决了关键性工程地质问题和难题,为节省投资,加快施工进度以及防治地质灾害提供了依据。     

城市滨水工业区的治理与重生:美国休斯敦港景观规划设计

With the increase of population in big cities, urban industrial districts are constantly seeking new development to realize the conversion from single-functional to multifunctional systems, to equip the city with diverse public spaces. The Port of Houston operates at the dynamic confluence of industry, transportation, and ecological systems, and has been a major driver of Houston’s economic growth over the last century. However, behind the prosperous economic growth, the port suffers from the isolation with the surrounding communities. Based on the “2045 Port Houston Master Plan,” the Landscape Planning and Design for the Port of Houston project focuses on urban space activation and ecological environment restoration through landscape planning and design methods, while facing the challenges of ecological environment, urban spatial pattern repositioning, and other urban issues. The project is expected to build an economically, socially, and ecologically healthy industrial waterfront zone. Port Houston, beyond its primary function as an economic driver, becomes a more visible and substantial force in urban governance of advancing the region’s activation and resilience.
