A stochastic model for estimating sustainable limits to wildlife mortality in a changing world
Conservation Biology, Volume 36, Issue 4, August 2022., 2022 Abstract Human‐caused mortality of wildlife is a pervasive threat to biodiversity. Assessing the population‐level impact of fisheries bycatch and other human‐caused mortality of wildlife has typically relied upon deterministic methods. However, population declines are often accelerated by stochastic factors that are not accounted for in such ...

Computational Intelligence and Neuroscience, Volume 2022, Issue 1, 2022., 2022 An important sign of the accessibility of Braille information is the realization of the mutual translation between Chinese and the Braille. Due to the irregularity and uncertainty of the Prevailing Mandarin Braille, coupled with the lack of a large‐scale Braille corpus, the quality of Chinese‐Braille translation seems to be poor.

不同桥臂电抗配置海上风电柔直换流站暂态应力与绝缘配合对比 [PDF]
全球能源互联网, 2022 全球海上风电柔性直流并网工程总容量已达10 GW，随着单位投资成本不断降低，柔性直流在未来一段时间内仍然是远海风电并网工程的首选方案。由于海上换流站交流电网主要由风电场构成，其暂态电气应力相比陆上换流站有所不同；此外，不同桥臂电抗配置方案会产生不同暂态电气应力。为此，重点针对对称单极系统，对比分析了阀交流侧和直流侧两种桥臂电抗配置方案海上换流站的暂态电气应力。通过建立PSCAD/EMTDC仿真模型，详细分析了海上换流阀交流侧单相接地、两相短路等关键性故障暂态应力特性差异与产生机理 ...
