An Improved N-dimensional NURBs-based Metamodel
Non Uniform Rational B-splines (NURBs) are proved to be very promising for metamodeling in engineering problems, because they have unique properties such as local modification scheme, strong convex hull property, and infinitely differentiability, etc. Since NURBs are defined by control points, knot vector, and weights associated with control points, the precision of NURBs is influenced by all o...
متن کاملDegenerate Lower Dimensional Tori in Hamiltonian Systems
We study the persistence of lower dimensional tori in Hamiltonian systems of the form H(x, y, z) = 〈ω, y〉 + 1 2 〈z, M(ω)z〉 + εP (x, y, z, ω), where (x, y, z) ∈ T n × Rn × R , ε is a small parameter, and M(ω) can be singular. We show under a weak Melnikov non-resonant condition and certain singularity-removing conditions on the perturbation that the majority of unperturbed n-tori can still survi...
متن کاملOne-dimensional model for doubly degenerate electrons
A Hubbard-like model with SU~4! symmetry for electrons with twofold orbital degeneracy is studied extensively. Exact solution in one dimension is derived by means of Bethe ansatz, where the sites are supposed to be occupied by at most two electrons. The features of ground state and excited states for repulsive coupling are shown. For finite N number of electrons, the configurations of quantum n...
متن کاملThree-Dimensional Simplicial Gravity and Degenerate Triangulations
I define a model of three-dimensional simplicial gravity using an extended ensemble of triangulations where, in addition to the usual combinatorial triangulations, I allow degenerate triangulations, i.e. triangulations with distinct simplexes defined by the same set of vertexes. I demonstrate, using numerical simulations, that allowing this type of degeneracy substantially reduces the geometric...
متن کاملThe modified degenerate kernel method for the multi-dimensional Fredholm integral equations of the second kind
In this paper, to investigate the multi-dimensional Fredholm integral equations of the second kind a modified degenerate kernel method is used. To construct the mentioned modified, the source function is approximated by the same method which employed to obtain a degenerate approximation of the kernel. The Lagrange interpolation method is used to make the needed approximations. The error and ...
