satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...

In this study, three typical and most extreme precipitation events in the history of North China are analyzed compared terms accumulated synoptical circulation using surface station observations ERA5 dataset. The happened August 1963 (“63.8” event, hereafter), 1975 (“75.8” event), July 2021 (“21.7” respectively, mainly Hebei Henan Provinces China. results show that maximum daily 4-day all excee...

introduction: infants born with congenital anomalies demand individualized nutritional evaluations and recommendations. the anatomical changes of neonatal surgical diseases create specific physiological constraints.patients with different congenital anomalies have different nutritional support needs. it is essential to know the exact physiology of these anomalies in order to be able to manage a...

BACKGROUND AND AIM: Dental anomalies are typically detected in radiographic screening. The present study was conducted with the aim of investigating the dental anomalies found in panoramic radiographs taken from the study population in Ardabil, Iran, in 2015-2016.METHODS: The present study was conducted on 1800 panoramic radiographs obtained from 799 men and 1001 women in the Radiology Departme...

The selection of most relevant features can significantly reduce the resource requirement associated with fuzzy ARTMAP neural networks for the classification of high-dimensional data extracted from satellite imagery. This paper introduces a variant of a wrapper-type feature ranking technique that was previously proposed for ARTMAP neural networks by Parsons and Carpenter. As with the originally...

Rank aggregation systems collect ordinal preferences from individuals to produce a global ranking that represents the social preference. Rank-breaking is a common practice to reduce the computational complexity of learning the global ranking. The individual preferences are broken into pairwise comparisons and applied to efficient algorithms tailored for independent paired comparisons. However, ...

This paper describes the relationship between the BrdUrd replicating pattern of a cell and its localization within the S phase by means of topographical features and DNA content measurement. The present study follows an objective ranking of the BrdUrd patterns obtained from a spectral analysis of the BrdUrd images. The pattern ranking was consistent with the DNA content increase throughout the ...

World Wide Web is considered the most valuable place for Information Retrieval and Knowledge Discovery. While retrieving information through user queries, a search engine results in a large and unmanageable collection of documents. A more efficient way to organize the documents can be a combination of clustering and ranking, where clustering can group the documents and ranking can be applied fo...
