Amazonian conservation across archipelagos of Indigenous territories
Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Indigenous stewardship is essential to the conservation of biocultural diversity, yet conventional conservation models often treat Indigenous territories (ITs) as homogeneous or isolated units. We propose that archipelagos of Indigenous territories (AITs), clusters of ITs that span geographies but are connected through shared cultural or ...

A social network analysis of an epistemic community studying neoliberal conservation
Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Researchers typically operate in epistemic communities: groups that share common approaches to research agendas and sociopolitical action and define areas of debate. Although productive in their own spheres, a lack of understanding among these communities can undermine scientific progress. Thus, analyzing epistemic communities is important for

Gaoya dianqi, 2022 隔离开关合闸不到位是危害电网安全运行的重要因素之一。针对目前缺乏快速有效的隔离开关合闸状态非接触自动检测技术的问题，文中以单臂水平伸缩式隔离开关为例，分析隔离开关运动过程，利用地面激光雷达获取隔离开关导电臂点云数据，对数据进行排序、分组及拟合，获得导电臂方向向量，提出了基于导电臂方向向量夹角的隔离开关合闸状态检测方法，开发了自动测量工具，并将该方法及工具运用于现场检测。现场试验结果表明，提出的检测方法及工具可实现隔离开关合闸状态的自动检测。该方法为隔离开关合闸状态的带电非接触检测提供了一种新的技术手段。

Uncovering Xi Jinping's Policy Agenda: Text As Data Approach
The Developing Economies, Volume 63, Issue 1, Page 9-46, March 2025.How many agendas has Xi Jinping put forth and promoted since taking office in 2012, and what are the types of agendas? How much of political attention has each agenda received, and how has the allocation of attention changed over time? We utilize a dataset of presidential statements, speeches, and reports from 2012 to 2022 and employed automated text ...

基于故障性质判断法的配电网中性点动态接地成套装置的开发及应用
Dianci bileiqi, 2019 通过对配电网中性点经消弧线圈接地方式,以及小电阻接地方式的特点分析及存在的问题进行了更加深入地研究,并开发研制出了配电网中性点动态接地成套装置。该装置具备消弧线圈接地与小电阻接地方式二者的优点,又能够灵活地解决两者存在的缺点。其功能在于配电网发生单相接地故障时,依据故障特征量和参数,就可以对故障的性质进行智能判断。满足在瞬时性接地故障时,故障点的绝缘水平能够快速恢复,提高了电网供电可靠性;同时在永久性单相接地故障时,能够快速且准确地选出,并切除故障线路,确保了设备和人身安全。经大量实验及运行结果证明 ...

Jianzhu Gangjiegou Jinzhan, 2023 由于几何非线性、连接的装配不确定性和控制器的作动器饱和，张拉整体结构的主动振动控制通常具有挑战性。为了解决这些技术难题，实施了快速模型预测控制（FMPC）策略，已有效地减轻结构振动。具体来说，基于Newmark方法的显式表达形式，避免了矩阵指数的计算，并在结构上的每个采样瞬间进行一次在线和两次离线瞬态分析，从二阶动态方程获得最优控制输入，而不形成扩展的状态空间方程。最后，将快速模型预测控制法应用于大型六胞标准张拉整体梁和六胞聚合式张拉整体梁的结构。示例结果证明，该方法应用在张拉整体结构是有效和可靠的 ...

Engaging youth in biodiversity education through visual narrative
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract Engaging youth in early and sustained conservation education has important implications for promoting positive attitudes and behaviors in those who will become the future of conservation and management. Toward this goal, visual narratives (comic books, graphic novels) are an increasingly popular method used by conservation scientists to ...
