Matching expert range maps with species distribution model predictions

open access: yesConservation Biology, Volume 34, Issue 5, Page 1292-1304, October 2020., 2020
Abstract Species’ range maps based on expert opinion are a critical resource for conservation planning. Expert maps are usually accompanied by species descriptions that specify sources of internal range heterogeneity, such as habitat associations, but these are rarely considered when using expert maps for analyses.

Inter-satellite link connection strategy for large-scale low earth orbit satellite networks [PDF]

open access: yes
For large-scale low earth orbit (LEO) satellite networks, two new inter-satellite link (ISL) connection strategies named Grid-V and Grid+ were proposed, which improved the traditional Grid connection strategy. The proposed strategies made full use of the

A comparative analysis of simulation approaches for predicting permeability and compressive strength in pervious concrete

open access: yesLow-carbon Materials and Green Construction
多孔混凝土在应对各种环境挑战和减轻气候变化影响方面发挥着重要的作用, 它有效减缓了洪水、地球热现象和地下水位下降等问题。多孔混凝土通常不含砂, 其关键性能指标在于其渗透性和抗压强度。准确预测上述性能对于节约成本和时间以及精确确定混凝土配合比至关重要。本文采用了不同的模型, 包括线性模型(LR)、非线性模型(NLR)和人工神经网络(ANN)模型, 对多孔混凝土的渗透性和抗压强度进行预测。基于多篇文献和实验研究的139个样本, 采用水灰比、粗骨料含量、水泥含量、孔隙率和养护时间等关键参数作为输入变量 ...
