Air motion determination by tracking humidity patterns in isentropic layers [PDF]
Determining air motions by tracking humidity patterns in isentropic layers was investigated. Upper-air rawinsonde data from the NSSL network and from the AVE-II pilot experiment were used to simulate temperature and humidity profile data that will ...

An SMP Soft Classification Algorithm for Remote Sensing [PDF]
, 2012 This work introduces a symmetric multiprocessing (SMP) version of the continuous iterative guided spectral class rejection (CIGSCR) algorithm, a semiautomated classification algorithm for remote sensing (multispectral) images.

WIREs Water, Volume 12, Issue 3, May/June 2025.A five‐step integrated modeling framework combines remote sensing and two‐dimensional hydraulic modeling to describe mesohabitats and assess suitability for target species. Remote sensing provides a Digital Terrain Model and an orthophoto (step 1) that can be used to classify and map environmental descriptors such as substrate and refugia (step 2).

The applicability and effectiveness of cluster analysis [PDF]
An insight into the characteristics which determine the performance of a clustering algorithm is presented. In order for the techniques which are examined to accurately cluster data, two conditions must be simultaneously satisfied.

Self-organization and clustering algorithms [PDF]
Kohonen's feature maps approach to clustering is often likened to the k or c-means clustering algorithms. Here, the author identifies some similarities and differences between the hard and fuzzy c-Means (HCM/FCM) or ISODATA algorithms and Kohonen's self ...

Remote Sensing for Monitoring Macroplastics in Rivers: A Review
WIREs Water, Volume 12, Issue 2, March/April 2025.Panoramic of remote sensing platforms for monitoring plastics in riverine environments. Platform elevation is directly related to image spatial resolution; see the example of a plastic bottle captured from Unmanned Aerial Systems (UASs). Letters stand for drone (D) and satellite (S) platforms: (Sa) Sentinel‐2; (Sb) Sentinel‐1 SAR; (Sc) Pleiades ...

Gaoya dianqi, 2006 模糊ISODATA算法在基于变压器DGA的故障诊断中存在一些问题。如:模式空间的划分缺乏依据,聚类分析时没有考虑各种气体成分对故障反映的灵敏度等。笔者对此进行了改进,引入了一个描述不同气体成分对故障反映灵敏度的指标权向量,并在每次迭代运算之后对聚类中心进行分解和合并处理。利用改进的ISODATA算法对3起变压器故障进行了分析,得到了比较高的判断准确度。
