CO, CO2, and SO2 detection based on functionalized graphene nanoribbons: First principles study
( Elsevier , 2020 , Article)In this study, density functional theory (DFT) has been used to build armchair graphene nanoribbon (AGNR) gas sensor and study its capacity to detect carbon monoxide (CO), carbon dioxide (CO2), and sulfur dioxide (SO2) ... -
Collapse dynamics for the discrete nonlinear Schrödinger equation with gain and loss
( Elsevier B.V. , 2019 , Article)We discuss the finite-time collapse, also referred as blow-up, of the solutions of a discrete nonlinear Schrödinger (DNLS) equation incorporating linear and nonlinear gain and loss. Such an extended DNLS system appears in ... -
Combined theoretical and experimental study of the transmission of tilted ion beams through macroscopic conical glass capillaries
( IOP Publishing , 2015 , Conference Paper)The transmission as a function of the tilt angle of a 3 keV Ar+ ion beam through a conical macroscopic glass capillary is studied theoretically and experimentally. It was found that the charge patches which are responsible ... -
Common Fixed Point Results of Set Valued Maps for Aφ-Contraction and Generalized ϕ-Type Weak Contraction
( MDPI AG , 2019 , Article)The solutions for many real life problems may be obtained by interpreting the given problem mathematically in the form f(x)=x . One such example is that of the famous Borsuk–Ulam theorem in which, using some fixed point ... -
Common fixed point theorems for two pairs of self-mappings in partial metric space using C-class functions on (ψ, ϕ)-contractive condition
( International Scientific Research Publications , 2018 , Article)The purpose of this paper is to introduce common fixed point results for two pairs of weakly compatible self-mappings in partial metric space using C-class functions on (ψ, ϕ)-contractive condition. Example and application ... -
Comparison of Interval Estimators of Pr(X < Y) in the Two-parameter Exponential Distribution
( Taylor and Francis Inc. , 2016 , Article)We consider confidence intervals for the stress-strength reliability Pr(X< Y) in the two-parameter exponential distribution. We have derived the Bayesian highest posterior density interval using non-informative prior ... -
Complete allocation sampling: An efficient and easily implemented adaptive sampling design
( Wiley , 2010 , Article)Adaptive sampling designs are becoming increasingly popular in environmental science, particularly for surveying rare and aggregated populations. An adaptive sample is one in which the survey design is modified, or adapted, ... -
Complex-impedance response of an Ag/TeO2-V2O5/Ag structure
( Elsevier , 2009 , Article)The ac conductivity of glass samples of composition 50 mol% TeO2 and 50 mol% V2O5 has been analyzed. The samples were prepared by the usual melt-quench method. The electrical conductance and capacitance were measured over ... -
