We propose a block Davidson-type subspace iteration using Chebyshev polynomial filters for large symmetric/hermitian eigenvalue problem. The method consists of three essential components. The first is an adaptive procedure for constructing efficient block Chebyshev polynomial filters; the second is an inner–outer restart technique inside a Chebyshev–Davidson iteration that reduces the computati...

Abstract: A permanent magnet (PM) synchronous generator system driven by wind turbine (WT), connected with smart grid via AC-DC converter and DC-AC converter, are controlled by the novel recurrent Chebyshev neural network (NN) and amended particle swarm optimization (PSO) to regulate output power and output voltage in two power converters in this study. Because a PM synchronous generator system...

Background Exploring changes in health inequality and its determinants over time is of policy interest. Accordingly, this study aimed to decompose inequality in neonatal mortality into its contributing factors and then explore changes from 1995-2000 to 2005-2010 in Iran.   Methods Required data were drawn from two Iran’s demographic and health survey (DHS) conducted in 2000 and 2010. Normalized...

background: despite significant reduction in global disease prevalence, leprosy still has a high rate of disability while its determinants are unfair and many of them are amendable. the objective of this study was to measure inequality of disability in leprosy in iran. methods: this was a cross‑sectional study (2006‑2007) on all living people affected by leprosy registered in w. azerbaijan prov...

background: infant mortality rate is a useful indicator of health conditions in the society, the racial and socioeconomic inequality of which is from the most important measures of social inequality. objectives: the aim of this study was to determine the socioeconomic inequality and its determinants regarding infant mortality in an iranian population. patients and methods: this cross-sectional ...

Keywords: Set-valued mapping Chebyshev center Uniformly convex Locally uniformly convex Chebyshev fixed point a b s t r a c t The existence of a continuous Chebyshev selection for a Hausdorff continuous set-valued mapping is studied in a Banach space with some uniform convexity. As applications, some existence results of Chebyshev fixed point for condensing set-valued mappings are given, and th...

Educational inequality is one of the types of inequality which always pervades on an educational system. The existence of the educational inequality alongside other inequalities and their interaction are the most important in a society. This paper attempts to examine the factors that affect educational inequality in Kazeroon city. The method of present study is survey and data collection tool i...
