Characterization of Retained Austenite in Advanced High‐Strength Steel
Scanning, Volume 2023, Issue 1, 2023., 2023 The retained austenite (RA) in advanced high‐strength steels directly affects their plasticity. It is very important for the accurate characterization of their content and types. This paper prepared three specimens with three different Mn contents (1.0%, 1.4%, and 1.7%) that are used to obtain high‐strength steel by ultrafast cooling heat treatment ...

Scanning, Volume 2022, Issue 1, 2022., 2022 Hydrogen embrittlement can easily occur in high strength martensitic steel, manifesting itself as a sudden failure or fracture without warning and greatly threatening the safety of automotive applications. Optimizing the composition of the alloy can be performed by matching heat treatment processing methods and controlling the precipitation amounts to ...

Study becomes insight: Ecological learning from machine learning
Methods in Ecology and Evolution, Volume 12, Issue 11, Page 2117-2128, November 2021., 2021 Abstract The ecological and environmental science communities have embraced machine learning (ML) for empirical modelling and prediction. However, going beyond prediction to draw insights into underlying functional relationships between response variables and environmental ‘drivers’ is less straightforward.

Trends and knowledge gaps in field research investigating effects of anthropogenic noise
Conservation Biology, Volume 35, Issue 1, Page 115-129, February 2021., 2021 Abstract Anthropogenic noise is a globally widespread sensory pollutant, recognized as having potentially adverse effects on function, demography, and physiology in wild animals. Human population growth and associated changes in urbanization, transportation, and resource extraction all contribute to anthropogenic noise and are predicted to increase in ...

Effects of spatial autocorrelation and sampling design on estimates of protected area effectiveness
Conservation Biology, Volume 34, Issue 6, Page 1452-1462, December 2020., 2020 Abstract Estimating the effectiveness of protected areas (PAs) in reducing deforestation is useful to support decisions on whether to invest in better management of areas already protected or to create new ones. Statistical matching is commonly used to assess this effectiveness, but spatial autocorrelation and regional differences in protection ...

Decision‐support tools for dynamic management
Conservation Biology, Volume 34, Issue 3, Page 589-599, June 2020., 2020 Abstract Spatial management is a valuable strategy to advance regional goals for nature conservation, economic development, and human health. One challenge of spatial management is navigating the prioritization of multiple features. This challenge becomes more pronounced in dynamic management scenarios, in which boundaries are flexible in space and ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

Gaoya dianqi, 2021 传统局部放电时频分析噪声抑制方法,存在时频分辨率低、可读性差和抑制噪声种类单一的局限。文中在同步压缩域中使用多级阈值方案对变压器局部放电检测时所受干扰:白噪声和窄带噪声进行抑制。同步压缩算法作为一种高分率的时频分析方法,旨在对时频域进行重新分配,更细致区分信号与噪声。多级阈值方案结合小波变换和同步压缩变换,利用信号的高阶统计特征计算噪声的初级阈值,完成对原始信号噪声的初步抑制;利用广义交叉验证算法求解噪声的次级阈值,完成对信号中残留噪声更进一步的抑制 ...

Research on the Noise Measurement and Control of Wheeled Excavator and Its Application [PDF]
, 2015 除可靠性与经济性外，NVH（Noise,Vibration,Harshness）性能也成为评价轮式挖掘机品质的重要指标之一。90年代初的北美、欧洲和日本就有许多企业及学者开始对工程机械的振动噪声进行研究，并取得了很多成果。中国在该领域的研究起步相对较晚，很多国产工程机械的性能都落后于欧洲、美洲和日本的产品，尤其在振动噪声方面的差距更大。为了提高工程机械的舒适性，本文对轮式挖掘机的噪声测试与控制技术进行了研究。 首先 ...
