abstract geopedology is a systematic approach of geomorphic analysis for soil mapping which focuses the field operation mainly on sample area. the purpose of this study is to determine the credibility of generalization of the results of geopedological approach for similar landforms in the borujen region, using diversity and similarity indices in a soil taxonomic hierarchical structure. after a ...

a field survey was conducted in wukari, taraba state to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. insects recovered were wet preserved in 70% ethanol except butterflies and moths. representativ...

Starting instead from a symmetric-antisymmetric reformulation we first show SSIM to be a contrast or visibility function in the classic sense. Furthermore, the previously enigmatic structural covariance is revealed to be the difference of variances. The second step, eliminating the intrinsic quadratic nature of SSIM, allows a near linear correlation with human observer scores, and without invok...

Is it possible to calculate a hash value for a document that captures its salient characteristics, such that a repository can be queried for like values and retrieve all “similar” documents? If so, similar documents could be easily identified by a simple SQL query without the need for a full text search engine. Such a value would allow systems to quickly identify duplicate or similar content be...

There are different approaches to the temporal study of time evolving systems. In this paper, this study is carried out by means of the comparison of time series. It is proposed as an improvement in the comparison of time series with the inclusion of qualitative knowledge. Taking into account the evolution of the values of the series, our approach uses a similarity index defined by qualitative ...

Graph similarity search under the graph edit distance constraint has received considerable attention in many applications, such as bioinformatics, data mining, pattern recognition and social networks. Existing methods for this problem have limited scalability because of huge amount memory they consume when handling very large databases with tens millions graphs. In article, we present a succinc...
