In text categorization, different supervised term weighting methods have been applied to improve classification performance by weighting terms with respect to different categories, for example, Information Gain, χ statistic, and Odds Ratio. From the literature there are three term ranking methods to summarize term weights of different categories for multi-class text categorization. They are Sum...

Recent attitude of vegetation assessors is using of new ecologic approaches to evaluate and analyse the complex rangeland ecosystems. Plant diversity is the most important indices to assess the ecological changes of rangelands. In order to survey of plant indices of rangelands, two exclosure areas (long-term and mid-term) and a grazing area in rangelands of Javaherdeh (Ramsar, Iran) were select...

For t a positive integer, the t-term rank of a (0, 1)-matrix A is defined to be the largest number of 1s in A with at most one 1 in each column and at most t 1s in each row. Thus the 1-term rank is the ordinary term rank. We generalize some basic results for the term rank to the t-term rank, including a formula for the maximum term rank over a nonempty class of (0, 1)-matrices with the the same...

Abstract Forecasting electrical energy demand and consumption is one of the important decision-making tools in distributing companies for making contracts scheduling and purchasing electrical energy. This paper studies load consumption modeling in Hamedan city province distribution network by applying ESN neural network. Weather forecasting data such as minimum day temperature, average day temp...

Two ways to deduce the equivalence of field equations general relativity and principle maximum force $c^4/4G$ - or equivalent power $c^5/4G$ are presented. A simple deduction inverse square gravity directly from arises. Recent apparent counterarguments refuted. New tests in astronomy, cosmology, electrodynamics, numerical gravitation quantum proposed.

introduction: the fetus needs a considerable amount of cholesterol for the development of tissues and organs.  studies have suggested that genetic and environmental factors influence the composition of cord blood lipoproteins.  in this study, we aim to assess the effect of gestational age, sex and birth weight on the cord blood lipoproteins. methods: we collected umbilical cord blood samples fr...
