– in this paper we consider some (α ,β ) -metrics such as generalized kropina, matsumoto and f (α β )2α = + metrics, and obtain necessary and sufficient conditions for them to be einstein metrics when βis a constant killing form. then we prove with this assumption that the mentioned einstein metrics must beriemannian or ricci flat.

Without the software development and software product knowledge it’s very complicated to understand, keep away from improvement in the quality of software. There should be some dimension process to forecast the software development, and to appraise software products and its quality. In This paper provides a brief view on Software Metrics, Software Quality and Software Metrics techniques that wi...

the general relatively isotropic mean landsberg metrics contain the general relativelyisotropic landsberg metrics. a class of finsler metrics is given, in which the mentioned two conceptsare equivalent. in this paper, an interpretation of general relatively isotropic mean landsberg metrics isfound by using c-conformal transformations. some necessary conditions for a general relativelyisotropic ...

We address the problem of class imbalance in supervised grammatical error detection (GED) for non-native speaker text, which is the result of the low proportion of erroneous examples compared to a large number of error-free examples. Most learning algorithms maximize accuracy which is not a suitable objective for such imbalanced data. For GED, most systems address this issue by tuning hyperpara...

Knowing the metrics related to cloud is very critical to enhance the performance of the cloud. To learn the metrics related to cloud like the infrastructure, structure and functionality of the cloud systems many models were described. This paper lists some of the technical models related to the cloud computing that enhances the cloud performance. The models that are discussed focusses on some m...

We show that the existence of a left-invariant pluriclosed Hermitian metric on unimodular Lie group with abelian complex structure forces to be 2-step nilpotent. Moreover, we prove flow starting from nilpotent preserves Strominger Kähler–like condition.
