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 ...

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 ...

Sonar Image Speckle Reduction Algorithm Base on Redundant Dictionary [PDF]
, 2016 由于水下环境的特殊性，水质对于声波的吸收、散射及混响等因素的存在严重影响了声纳成像效果，尤其是后向散射效应、混响等使得声纳图像中存在强烈的噪声，严重降低了声纳图像的质量，从而给后续的图像处理和应用带来了诸多不利的影响。因此，如何构建出针对水下图像特点的去噪处理算法具有重大的意义。 论文首先分析总结了声纳图像成像影响因素和成像特点，与传统的光学图像相比，声纳图像具有斑点噪声严重、分辨率低、边缘模糊、对比度低等特点。并在其成像机理的基础上得到其斑点噪声的统计分布模型，建立斑点噪声图像的乘性瑞利模型。 然后 ...
