متن کاملComputational and Programming Aspects of Transition Elements in a Three-dimensional Finite Element Program
The performance of any finite element (FE) structural analysis is directly related to the global number of nodes and degrees of freedom (DOF) of the discretized structure and mesh distribution attributes. It is obvious that the appropriate numerical analysis needs finer elements in the zone of interest, e.g. zone of high stress concentration and intensity, and coarser elements for farther porti...
متن کاملWeak transition matrix elements from finite-volume correlation functions
The two-body decay rate of a weakly decaying particle (such as the kaon) is shown to be proportional to the square of a well-defined transition matrix element in finite volume. Contrary to the physical amplitude, the latter can be extracted from finite-volume correlation functions in euclidean space without analytic continuation. The K → ππ transitions and other non-leptonic decays thus become ...
متن کاملVolume integral equation formulation for scattering using conformal finite elements
A method of moments solution of volume integral eqna,tions (VTEs) for scattering and radiation problems involving arbitrarily shaped inhomogeneous dielectric structures is presented. The inhomogeneous region is modeled using second order hexahedral elements whereas low order conformal basis functions within these elements are used for the method of moments expansion of the unknown. The resultin...
متن کاملSome combinatorial aspects of finite Hamiltonian groups
In this paper we provide explicit formulas for the number of elements/subgroups/cyclic subgroups of a given order and for the total number of subgroups/cyclic subgroups in a finite Hamiltonian group. The coverings with three proper subgroups and the principal series of such a group are also counted. Finally, we give a complete description of the lattice of characteristic subgroups of a finite H...
