A one-step iteration with errors is considered for a family of asymptotically nonexpansive nonself mappings. Weak convergence of the purposed iteration is obtained in a Banach space.

The three-term Lanczos process for a symmetric matrix leads to bases for Krylov subspaces of increasing dimension. The Lanczos basis, together with the recurrence coefficients, can be used for the solution of symmetric indefinite linear systems, by solving a reduced system in one way or another. This leads to well-known methods: MINRES (minimal residual), GMRES (generalized minimal residual), a...

introduction: the aim of this study was to assess of both implicit and explicit motor sequence learning in children with attention deficit hyper activity disorder (adhd) and typical peers , by serial reaction time task. materials and methods: the sample size for each group was 12. the study sample was included 24 children with adhd, in explicit learning group and implicit learning group.  and 2...
