The atomic layer deposition (ALD) reaction of Al2O3 at graphene nanoribbon open edges has been studied theoretically by ab initio density functional theory and transition state rate theory. The structures of reactants, adsorption complexes, products, and transition states of the model reactions were optimized at the B3LYP/6311G(d,p) level of theory. The potential energy profiles have revealed t...

We study the coherent spin-polarized transport through a zigzag-edge graphene flake (ZGF), using Hubbard model in the nearest neighbor approximation within the framework of the Green function’s technique and Landauer formalism. The system considered consists of electrode/ (ZGF)/electrode, in which the electrodes are chosen to be armchair nanoribbons. The study was performed for two types of ele...

Linear and nonlinear issues in the problem of the subcritical transition to turbulence are examined on the basis of a full phase-space analysis of a simplified model that mimics hydrodynanJics governed by the Navier-Stokes equations. The simplicity of the model, which involves only two variables and displays both non-normal linear terms and

The study of spherical representations of the Jacobi group begun in [Sch1] is continued. Using certain index shifting operators, the notion of age of such a representation is introduced, as well as the notion of a local newform. The precise structure of the space of spherical vectors, in particular its dimension, is determined in terms of the age. The age of the spherical principal series repre...

3D SIFP (3 dimensional scale invariant features points) can embody the great changes in video both in spatial and temporal domain, which can assure the stability against spatial and temporal attacks. As a result, they enforce the robustness of video watermarking. In this paper, a novel video watermarking scheme exploiting 3D SIFP in DCT (Discrete Cosine Transform) domain is proposed. We establi...

I will give a broad overview of what has become the standard paradigm in cosmology. I will describe the relational (à la Leibnitz) notion of time that is often used in cosmological calculations and discuss how the local nature of Einstein’s equations allows us to translate this notion into statements about ‘initial’ data. Classically this relates our local definition of time to a quasi-local re...

This paper uses Kalman filter theory to design a state estimator for noisy discrete time Takagi–Sugeno (T–S) fuzzy models. One local filter is designed for each local linear model using standard Kalman filter theory. Steady state solutions can be found for each of the local filters. Then a linear combination of the local filters is used to derive a global filter. The local filters are time-inva...
