In marine ecology research, it is crucial to accurately identify the marine mammal species active in the target area during the current season, which helps researchers understand …
该文基于多源辐射观测资料，采用随机森林（RF）算法、季节差分自回归移动平均（SARIMA）模型及特征重要性等方法，对山东省济南市太阳辐射长期变化趋势和影响因素进行综合分析。结果显示：RF模型拟合月太阳辐射效果较好，决定系数和平均绝对百分比误差分别为0.92和9%，优于SARIMA模型；济南市及周边地区月太阳辐射1980—2020年经历“变暗”到“变亮”的过程 …
In this paper, an event-triggered adaptive tracking control strategy is proposed for strict-feedback stochastic nonlinear systems with predetermined finite-time performance. …
This article investigates the problem of adaptive tracking control for stochastic nonlinear systems with deferred state constraints. The novel unified universal barrier function …
We experimentally demonstrate the highly-efficient nonlocal erasing and writing of ferroelectric domains using a femtosecond laser in lithium niobate. Based on the induction of a …
In this paper, the control issue of adaptive fault-tolerant is studied for a class of stochastic nonlinear systems with multiple faults and full state constraints, with multiple …
Soil carbon content prediction based on hyperspectral images can achieve large-scale spatial measurement, which has the advantages of wide coverage and fast information collection, …
Sound event detection (SED) is a widely studied field that has achieved considerable success. The dynamic routing mechanism of capsule networks has been used for SED, but its …
