Single-Walled Carbon-Nanotubes-Based Organic Memory Structures
( MDPI AG , 2016 , Article)The electrical behaviour of organic memory structures, based on single-walled carbon-nanotubes (SWCNTs), metal–insulator–semiconductor (MIS) and thin film transistor (TFT) structures, using poly(methyl methacrylate) (PMMA) ... -
A point symmetry based method for transforming ODEs with three-dimensional symmetry algebras to their canonical forms
( Elsevier Inc. , 2016 , Article)We provide an algorithmic approach to the construction of point transformations for scalar ordinary differential equations that admit three-dimensional symmetry algebras which lead to their respective canonical forms. -
C-class functions with new approach on coincidence point results for generalized (ψ,φ)-weakly contractions in ordered b-metric spaces
( SpringerOpen , 2016 , Article)In this paper, by using the C-class functions and a new approach we present some coincidence point results for four mappings satisfying generalized (ψ,φ) -weakly contractive condition in the setting of ordered b-metric ... -
Effect of Zn and Ni substitution on structural, morphological and magnetic properties of tin oxide nanoparticles
( Elsevier , 2016 , Article)Structural, morphological, optical and magnetic properties of Zn and Zn–Ni co-doped tin oxide (SnO2) nanoparticles synthesized by sol-gel method. The influence of doping concentration on phase and particle size of the ... -
Linear hydrogen gas sensors based on bimetallic nanoclusters
( Elsevier Ltd , 2016 , Article)This work reports on the fabrication of hydrogen gas sensors based on bimetallic palladium-copper nanoclusters. The nanoclusters were generated by sputtering and inert-gas condensation inside an ultra-high vacuum (UHV) ... -
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 ... -
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 ... -
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 ... -
Approximate analytic solutions of transient nonlinear heat conduction with temperature-dependent thermal diffusivity
( Hindawi Publishing Corporation , 2014 , Article)A new approach for generating approximate analytic solutions of transient nonlinear heat conduction problems is presented. It is based on an effective combination of Lie symmetry method, homotopy perturbation method, finite ... -
Fixed point theorems for weakly T-Chatterjea and weakly T-Kannan contractions in b-metric spaces
( Springer-Verlag , 2014 , Article)In this work, we obtain some fixed point results for generalized weakly T-Chatterjea-contractive and generalized weakly T-Kannan-contractive mappings in the framework of complete b-metric spaces. Examples are provided in ... -
On convergence of an implicit iterative algorithm for non self asymptotically non expansive mappings
( Hacettepe University , 2014 , Article)In this paper, we study an implicit iterative algorithm for two nite families of nonself asymptotically nonexpansive mappings. We prove some weak and strong convergence theorems for this iterative algo- rithm. Our results ... -
Fuzzy linear programming for supply chain management in steel industry
( Hikari Ltd. , 2014 , Article)Linear programming is one of the frequently applied tools in supply chain management. However, managers and decision makers may lack information about exact values of most of the parameters used in the optimization models. ... -
Asymptotic stability of time-varying distributed parameter semi-linear systems
( IFAC , 2014 , Conference Paper)The asymptotic behaviour is studied for a class of non-linear distributed parameter time-varying dissipative systems. This is achieved by using time-varying infinite-dimensional Banach state space description. Stability ... -

Temperature dependence of the pressure induced monoclinic distortion in the spin S=1/2 Shastry–Sutherland compound SrCu2(BO3)2
( Elsevier Ltd , 2014 , Article)We investigate the monoclinic distortion that occurs at 4.7 GPa at room temperature in the frustrated Shastry-Sutherland model quantum magnet SrCu 2(BO3)2 as a function of pressure and temperature by means of powder and ... -
Isomorphic Hilbert spaces associated with different complex contours of the PT-symmetric (-x^4) theory
( World Scientific Publishing Co. , 2014 , Article)In this work, we stress the existence of isomorphisms which map complex contours from the upper half to contours in the lower half of the complex plane. The metric operator is found to depend on the chosen contour but the ... -
Asymptotic freedom, dimensional transmutation, and an infrared conformal fixed point for the ? -function potential in one-dimensional relativistic quantum mechanics
( American Physical Society , 2014 , Article)We consider the Schr?dinger equation for a relativistic point particle in an external one-dimensional ?-function potential. Using dimensional regularization, we investigate both bound and scattering states, and we obtain ... -
Correlated decay of triplet excitations in the shastry-sutherland compound SrCu2 (BO3)2
