investigation of desertification trend requires an understanding of phenomena that create changes singly or action and reaction together in an area that these changes were led to the desertification and land degradation. in the investigation of pedological criterion affecting on land degradation in alluvial fans, first, the map of units was created by overlaying and crossing maps of slope class...

pedological criterion affecting desertification in alluvial fans was investigated, for which the map of units was prepared by crossing maps of land use, geology, slope classes and grid layer created by the extension of et geo-wizards in arcgis 10.3. three indices of salinity, erodibility, and permeability of soil were considered and classified. weights of criteria and consistency ratio were cal...

We introduce the notion of 3-Hom-Lie-Rinehart algebras and systematically describe a cohomology complex by considering coefficient modules. Furthermore, we consider extensions algebra characterize first space in terms group automorphisms an A-split abelian extension equivalence classes extensions. Finally, study formal deformations algebras.

Let B(H) be the algebra of all bounded linear operators on a complex separable infinite dimensional Hilbert space H. In this paper we minimize the Schatten Cp-norm of suitable affine mappings from B(H) to Cp, using convex and differential analysis (Gâteaux derivative) as well as input from operator theory. The mappings considered generalize Penrose’s inequality which asserts that if A and B den...

There are several ways to categorize the Japanese lexicon. Like many of the world’s languages, it is possible to divide Japanese into so-called lexical categories—within Japanese, nouns, verbs, adverbs, and adjectives are among those that are generally recognized. Additionally, there are some theories that claim the necessity of a “verbal noun” part of speech; however, these claims are not enti...

The proliferation of contextualized knowledge in the Semantic Web (SW) has led to the popularity of knowledge formats such as quads in the SW community. A quad is an extension of RDF triple with the contextual information of the triple. We in this paper, study the problem of query answering over quads augmented with forall-existential bridge rules that enable interoperability of reasoning betwe...

Automatically extracting semantic information about word meaning and document topic from text typically involves an extensive number of classes. Such classes may represent predefined word senses, topics or document categories and are often organized in a taxonomy. The latter encodes important information, which should be exploited in learning classifiers from labeled training data. To that exte...

the main purpose of this study was to measure the level of technical efficiency of sugar beet producers and determination of factors affecting it. a sample of 144 producers in the main sugar beet growing areas of hamedan, nahavand, malayer and asadabad were selected by two stage cluster sampling method. data were collected through interviews during farming year of 2001-2002.technical efficiency...

Résumé. Dans cet article nous abordons le problème de la classification (ou clustering) dans le but de découvrir des classes avec recouvrements. Malgré quelques avancées récentes dans ce domaines, motivées par des besoins applicatifs importants (traitements des données multimédia par exemple), nous constatons l’absence de solutions théoriques à ce problème. Notre étude consiste alors à proposer...
