基于改进箱线图和ISMAHHO-KELM的变压器油中溶解气体体积分数预测
Gaoya dianqi油中溶解气体分析能够有效地揭示变压器内部的运行状况，在评估变压器运行状态和预测潜在故障方面具有重要作用。为此文中提出一种基于改进箱线图和ISMAHHO-KELM的变压器油中溶解气体体积分数预测方法。首先，为提高数据质量，利用基于中位偏差系数的改进箱线图对原始时间序列进行离群值检测和校正；然后采用变分模态分解对校正过的时间序列进行分解，得到多个子序列，以削弱时间序列的非平稳性；其次，通过核极限学习机模型预测子序列，同时提出改进黏菌—哈里斯鹰算法优化其超参数；最后，重构各子序列的预测值，得到最终预测结果 ...

野生动物学报全球范围内饲养与圈养野生动物的目的是保护、研究、教育和娱乐。保障圈养动物福利不仅是一项道德义务，更是当下的迫切需求。本研究探讨了圈养野生动物的福利现状，评估了当前改善福利的主要策略，并着重剖析了常见的挑战。相较于自然生境，圈养环境下的动物在食物获取、兽医护理及免受捕食风险方面具有一定优势，但是它们在空间活动、社交互动及行为自主性等方面受到诸多限制，这可能导致刻板行为的产生以及慢性压力的积累，对活动范围广泛和认知较复杂的物种影响更为显著。当前改善圈养野生动物福利的主要措施包括丰容 ...
