The Limits of Depoliticized Water–Energy Diplomacy: Insights From the UAE–Israel–Jordan Water‐for‐Energy Deal

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT This paper examines the rise and collapse of the 2021 United Arab Emirates (UAE)–Israel–Jordan Water‐for‐Energy Deal, a landmark initiative that sought to exchange Jordanian solar energy for Israeli desalinated water. Presented as a breakthrough in regional cooperation and environmental peacebuilding, the agreement was brokered under the ...

基于GoogLeNet Inception-V3模型的电力设备图像识别

open access: yesGaoya dianqi, 2020
随着电网智能运检的不断推进,电力设备状态监测产生了海量图像数据,然而目前尚无十分有效的方法对其进行智能分类识别。为解决机器学习对图像中的复杂特征提取困难和常规卷积神经网络学习能力不足带来的数据堆积和误判等问题,提出一种基于GoogLeNet Inception-V3模型的电力设备图像识别方法。首先介绍电力设备图像识别的模型结构及实现步骤,随后阐述该模型在特征提取中的高效性和准确性,最后通过实验证明该方法的优势。研究结果表明,提出方法对断路器、电流互感器、绝缘子、避雷器和电压互感器的平均识别准确率高达92.

Study of the effects of temperature on the growth of two strains of petroleum bacteria by microcalorimetry(微量量热法研究温度对两种石油菌生长的影响)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2000
本文采用微量量热法测定了两种石油菌在不同温度下的生长热谱图。按限制性条件下微生物生长模型,用三点法进行了数学处理,得出了生长速率常数(k);计算机拟合k-T非线性方程,得到了石油菌I,II的最佳生长温度(Topt)分别为322.07K和322.85K。按阿仑尼乌斯公式和过渡态理论计算得到有关热动力学函数,并根据所得结果对两种石油菌的生长代谢过程进行了热动力学分析。

基于可见光图像和机器学习的金具温升识别方法

open access: yesGaoya dianqi, 2022
基于光辐射的测温技术一般工作在热辐射较强的红外波段,基于光反射的测温技术虽然可以工作在可见光波段,但目前使用条件只限于暗环境下正入射单波长的光源,而电力设备工作在日光下难以使用该技术。文中通过数字图像处理技术和机器学习方法,将热调制光反射技术扩展到不需要正入射和固定光源的情况,利用日光实现常温电力金具表面温升识别。在日光下利用3种手机拍照建立了110 kV输电线路一种金具不同日光环境(每个温度下日光照度有3种)的图像库4 500幅,3种不同金具(每个温度下日光照度一种)的图像库每种金具1 500幅 ...
