    Influence of Urban Development on Extreme Precipitation in Plateau Lake Basin by LI Baofen, LI Xiaopeng, CAO Yimei, JIN Zhuo

    Published 2023-01-01
    “…Studying the influence of urban development on extreme precipitation in the lake basin region is of practical significance for urban flood control and disaster reduction,forecasting and early warning capability increase and emergency response capacity building,“four pres” improvement,and risk tackling of extreme precipitation and waterlogging disasters.Taking Kunming,a city in the Yunnan Plateau Basin,as an example,this paper adopts mathematical statistical methods to analyze the effect of urban development on the extreme precipitation index in the central urban area of the lake basin,the basin edges,and peripheral hilly areas of the city.The results show that urban development exerts different degrees of influence on various extreme precipitation indexes in lake basin areas,basin edges,and peripheral hilly areas of the basin, with the strongest,weakest,and middle effects on the basin edges, hilly areas,and lake basin areas respectively.Due to topography and the urban heat island effect,urban development also causes uneven increase and decrease in the extreme precipitation index in various areas such as lake basin areas,basin edges,and hilly areas.…”

    Investigating the link between a layer thickness and surface relief depth in an azo poly(ether imide) by Mateusz Nieborek, Dariusz Szmigiel, Paweł Komorowski, Agnieszka Siemion, Jolanta Konieczkowska, Ewa Schab-Balcerzak, Anna Kozanecka-Szmigiel

    Published 2025-01-01
    “…We performed prolonged holographic recordings on the layers of the same azobenzene poly(ether imide), which had substantially different optical transmittances at the recording wavelength and revealed that the depths of the inscribed relief structures increased with the polymer thickness from a nondetectable value up to almost 2 µm, unaffected by the presence of a polymer-glass substrate interface in either sample. We proposed the mathematical model for the relief buildup process under irradiation and validated the topographic data by their Fourier analysis related to optical measurements of the grating diffraction efficiencies. …”

    Variable Transmission Range Routing Protocol Based on Vehicle Density in VANET by Rong Cai, Guoan Zhang, Yuebo Wu

    Published 2015-03-01
    “…In order to solve the problem of unstable connectivity and high bit error rate,which are caused by rapid changes in the density of vehicles on the road,while the transmission radius remained unchanged,a variable transmission range routing protocols based on vehicle density in vehicular Ad-Hoc network was proposed.According to different vehicle density,node could adjust the farthest transmission distance and reduce the transmission latency of the message,which could ensure high connection probability of the network.Based on homogeneous poisson point process model,the change conditions of transmission range with different vehicle density were deduced,and its feasible was proved.Furthermore,mathematical calculate formula of average latency was obtained according to the theoretical analysis.At last,variable transmission range routing protocol based on vehicle density and fixed transmission range routing protocol were compared by simulation.The simulated results show that the proposed protocol can be applied in actual environments,and the message can be transmitted fast from source node to destination node under the condition of high connection probability.…”
