Fixed point results for generalized chatterjea type contractive conditions in partially ordered G-metric spaces
(
Hindawi Publishing Corporation
, 2014 , Article)
In the framework of ordered G -metric spaces, fixed points of maps that satisfy the generalized Chatterjea type contractive conditions are obtained. The results presented in the paper generalize and extend several well ...
Electrodeposition of nanocrystalline Ni-Mo alloys from alkaline glycinate solutions
(
Electrochemical Science Group
, 2014 , Article)
The induced electrodeposition of nanocrystalline Ni-Mo alloys was investigated using two different molar ratios of Ni:Mo in sodium glycinate solution at pH 9.3. The chemical nature of the Ni2+ and MoO4 2- in alkaline ...

Existence and approximation results for SKC mappings in CAT(0) spaces
(
Springer International Publishing
, 2014 , Article)
Recently, Karap?nar and Tas (Comput. Math. Appl. 61:3370-3380, 2011) extended the class of Suzuki-generalized nonexpansive mappings to the class of SKC mappings. In this paper, we investigate SKC mappings to get a criterion ...
Parallel LQP alternating direction method for solving variational inequality problems with separable structure
(
Springer International Publishing
, 2014 , Article)
In this paper, we propose a logarithmic-quadratic proximal alternating direction method for structured variational inequalities. The predictor is obtained by solving series of related systems of nonlinear equations, and ...
