First order perturbation effects in iron-dominated two-dimensional symmetrical multipoles

Fifth-order two-dimensional Raman spectra of CS 2 are dominated by third-order cascades

We have demonstrated that fifth-order stimulated Raman spectra of the intermolecular modes in CS 2 are dominated by cascading third-order processes. Previous studies have successfully discriminated against a sequential cascading process, but did not account for parallel third-order cascades. All of our measured spectra were successfully simulated considering only cascades built directly from ou...

First order transition in two dimensional coulomb glass

We have studied the ground states of two dimensional lattice model of Coulomb Glass via Monte Carlo annealing. Our results show a possibility of existence of a critical disorder (Wc) below which the system is in the charge ordered phase and above it the system is in the disordered phase. We have used finite size scaling to calculate Wc = 0.2413, the critical exponent of magnetization β = 0 indi...

Realization of first-order two-dimensional all-pass digital filters

A New Guideline for the Allocation of Multipoles in the Multiple Multipole Method for Two Dimensional Scattering from Dielectrics

A new guideline for proper allocation of multipoles in the multiple multipole method (MMP) is proposed. In an ‘a posteriori’ approach, subspace fitting (SSF) is used to find the best location of multipole expansions for the two dimensional dielectric scattering problem. It is shown that the best location of multipole expansions (regarding their global approximating power) coincides with the med...

Symmetrical Two-Dimensional PCA with Image Measures in Face Recognition

In this paper, weextensively investigate symmetrical two‐dimensional principal component analysis (S2DPCA) and introduce two image measures for S2DPCA‐based face recognition, volume measure (VM) and subspace distance measure (SM). Although symmetrical featuresare an obviously but not absolutely facial characteristic, they have been successfully applied to PCA and 2...
