Absorption Spectra of a Graphene Embedded One Dimensional Fibonacci Aperiodic Structure

In this paper, we explore the linear response of one dimensionalquasiperiodic structure based on Fibonacci sequence composed of silicon dioxide,polystyrene and graphene materials. Here, a graphene monolayer is sandwichedbetween two adjacent layers. The numerical results are obtained by using the standardtransfer matrix method. Due to the presence of graphene sheet in eac...

Reconstruction from Irregular Samples with Improved Locality

Estimation of Hydrodynamic Coefficients of Zouzan Plain Aquifer Using of Electrical Sounding Data

Knowledge of hydrodynamic coefficients is necessary for the determination of natural water flow through an aquifer and management of ground water resource. In this study, in order to determination of hydrodynamic coefficients of Zouzan aquifer results of 112 electrical sounding have been used. Quantitative interpretation was done by using IPI2WIN. Values of formation factor and porosity were de...

Convergence of Laplacian spectra from random samples

Eigenvectors and eigenvalues of discrete graph Laplacians are often used for manifold learning and nonlinear dimensionality reduction. It was previously proved by Belkin and Niyogi [3] that the eigenvectors and eigenvalues of the graph Laplacian converge to the eigenfunctions and eigenvalues of the Laplace-Beltrami operator of the manifold in the limit of infinitely many data points sampled ind...
