Large plane displays are often achieved by combining tiled imaging elements, which give the appearance of a single, seamless display. However, this is difficult to realize in practical use, since differences in color will make the tiles distinct even if the geometric calibration is perfect. The paper presents an approach of color calibration using cubic Bspline. According to the theory of cubic...

In this paper, numerical solutions of the nonlinear Benjamin-Bona-Mahony-Burgers (BBMB) equation are obtained by a method based on collocation of cubic B-splines. Applying the Von-Neumann stability analysis, the proposed method is shown to be unconditionally stable. The method is applied on some test examples, and the numerical results have been compared with the exact solutions. The L∞ and L2 ...

From the quark confinement idea, we conjecture that the quarks compose colorless particles (uud and udd the Lee Particles) and then the Lee Particles construct a body center cubic lattice in the vacuum. In terms of the energy band theory, from the symmetries of the body center cubic periodic field, we deduce the baryon spectrum (with a united mass formula) using only 2 flavored quarks u and d. ...

A comparison between experimental and theoretical electron energy loss near edge structure ~ELNES! of B and N K edges in cubic boron nitride is presented. The electron energy loss spectra of cubic boron nitride particles were measured using a scanning transmission electron microscope. The theoretical calculation of the ELNES was performed within the framework of density functional theory includ...

In this paper, we will apply cubic B-splines on a uniform mesh to explore the numerical solutions and numerical derivatives of a class of nonlinear second-order boundary value problems with two dependent variables. Our new method is based on the cubic spline interpolation. The analytical solutions and any-order derivatives can be well approximated with 4th order accuracy. Furthermore, our new m...

Suppose G is a graph with n vertices and m edges. Let n′ be the maximum number of vertices in an induced bipartite subgraph of G and let m′ be the maximum number of edges in a spanning bipartite subgraph of G. Then b(G) = m′/m is called the bipartite density of G, and b∗(G) = n′/n is called the bipartite ratio of G. This paper proves that every 2connected triangle-free subcubic graph, apart fro...

2014 Procedures utilizing an extension of the Van der Pauw technique are developed to distinguish by weak field galvanomagnetic measurements cubic and non-cubic symmetries. We consider (001), (110) and (111) oriented layers for which analytic expressions are given. Planar circular samples may be used. We have also found that in general when B = (Bu, Bv, Bw) a skewed behaviour is expected such t...

Real-space Green’s tensors are presented for the calculation of the stress or strain in infinite cubic crystals containing buried quantum wires or dots of arbitrary shape and composition, including the cubic anisotropy of elastic constants. The Green’s tensors are obtained as a polynomial series to second order in , an expansion coefficient defined in terms of the elastic stiffnesses. The zerot...

We report on the unconventional magnetism in the cubic B-site ordered double perovskite Ba2YMoO6, using ac and dc magnetic susceptibility, heat capacity and muon spin rotation. No magnetic order is observed down to 2 K while the Weiss temperature is approximately -160 K. This is ascribed to the geometric frustration in the lattice of edge-sharing tetrahedra with orbitally degenerate Mo5+ s=1/2 ...
