Evaluation of Urban Water System Development from the Perspective of Space by XIE Qianwen, LIU Jiangtao, WEI Jie, REN Dawei

“…To adapt to the reform of spatial planning in the new era,this study evaluates the urban water system from the new perspective of space and lays the foundation for the future use of spatial means to realize the optimization and sustainable development of urban water system functions.Taking Shenzhen as an example,this paper divides its urban water system space into four types,namely,resource ecology space,engineering facility space,water-city integrated space,and safety risk space,and evaluates them from the dimensions of the total space,composition and layout,system carrying capacity,and space quality.The results indicate that the space occupancy rate of the water system is generally low,and the local water resources and the carrying capacity of the water environment are limited,which are vulnerable to multiple disasters of floods and surges.The potential risk areas are mainly distributed in densely populated areas and industry-intensive areas.The spatial service quality of the water system has great potential for improvement considering the low biodiversity of rivers and lakes,the insufficient attraction of waterfront space,and a low proportion of the complex utilization of facility space.…”

An energy balance AODV protocol with multicast route discovery for wireless body area networks by Jin TAN, Yujuan ZHANG

“…In AODV protocol with the dynamic topology networks，the source node S requests a route to an arbitrary destination node D with flooding broadcast the RREQ message，but there is only one destination node sink in a WBAN，other nodes involved in receiving and forwarding RREQ have wasted energy except the nodes on minimum hop count routing.An energy balance AODV protocol with multicast route discovery for wireless body area networks was proposed，it increased the minimum hop count to sink hops，the next hop node to sink next and the node itself has the forwarding capability isforward three parameters in a hello message，and selects neighbors which could reach the sink only to participate in forwarding the RREQ message.This protocol effectively reduces the energy cost of the routing discovery through changing the broadcast to multicast，and prolongs the service life of WBAN with energy balance.The performance analysis and simulation experiment indicate that the proposed protocol is more advantaged than similar EAAODV in the number of RREQ，packet delivery ratio and energy consumption.…”

The politicisation of the climate emergency: the case of the 2019 United Kingdom general election by Alma-Pierre BONNET

Research on Flow Regime Hydraulics of Sluice-Passing Flows in Reconstruction Design of Large Sluice in Meandering River Channels by ZHANG Zhouwen

“…Large sluices in meandering river channels have large sluice-passing flow rates and turbulent flow regimes during floods,and downstream energy dissipaters of the sluice cannot be easily repaired once they are damaged by erosion.Taking the reconstruction of the Jimei Sluice as a research project,this paper tries to solve the problem that how to make the reconstructed sluice avoid the large scour pit that has a size of 50 000 m² and a maximum depth of 23 m and is formed by the erosion of current downstream stilling pools.In addition,the paper uses the technical route of changing the layout of the sluice opening and the angle between the sluice axis and the river channel centerline and establishes a two-dimensional hydrodynamic mathematical model to analyze the water level,sluice-passing flow regimes,and erosion.The results of the comparison find that the angle between the sluice axis and the river channel centerline is 88° (rotating counterclockwise by 2°),and the full-depth sluice scheme is suitable.The research ideas and methods can provide a reference for similar projects.…”

Coral Reef Conservation Strategies for Everyone by Kathryn E. Lohr, Joshua T. Patterson

“…About 400 million people rely on coral reef fish as a source of protein; about 6 million people make a living by catching and selling coral reef fish and invertebrates; tourism activities like SCUBA diving and snorkeling provide revenue of US $9.6 billion per year; and reefs reduce wave energy by 97%, helping to protect 197 million people in coastal areas from beach erosion, wave energy, and flooding. Learn how you can help protect these fragile, essential ecosystems from threats in this 7-page fact sheet written by Kathryn E. …”

Marinesque (Loupian, Hérault) : un relais routier sur la voie Domitienne by Iouri Bermond, Michel Christol, Michel Feugère, Christophe Pellecuer, Corinne Sanchez

“…The construction of the site, in the second quarter of the 1st century BC, could be considered a local initiative on the outskirts of lands that had been cultivated since the Iron Age in order to take advantage of its proximity to a public road. The repeated flooding of the river and the development of new forms of land ownership – legal evidence of which was discovered in the form of a boundary marker – most likely led to the site being abandoned at the beginning of the Early Empire.…”

QoE utility function-based cross-layer resource allocation in multi-user MIMO-OFDM systems by Da-ming WANG, Song CHEN, Wei-jia CUI, Qiang WANG

“…Resource allocation problem was investigated for downlink multi-user MIMO-OFDM systems.A QoE (quality of experience) utility function was given according to the characteristics of real-time (RT) and non real-time (NRT) ser-vices,and then a RT ＆amp; NRT QoE utility function-based cross-layer resource allocation algorithm was proposed.The al-gorithm firstly used the designed utility function to calculate the delta QoE,which was offered by users got resource.Secondly,it classified users according to their delta QoE and then allocated time-frequency blocks.Thirdly,it optimized the power allocation result by implementing pseudo water flooding power allocation.Simulation results show that com-pared with the existing algorithm,the proposed algorithm is better in the user average QoE,average packet delay to real time services,average packet lost rate to non real time services as well as sum throughput of system.…”
