Starting with a numerically non-critical (at p) Hecke eigenclass f in the homology of a congruence subgroup Γ of SL3(Z) (where p divides the level of Γ) with classical coefficients, we first show how to compute to any desired degree of accuracy a lift of f to a Hecke eigenclass F with coefficients in a module of p-adic distributions. Then we show how to find to any desired degree of accuracy th...

Introduction:  Stereotactic  radiosurgery  is  a  technique  for  the  treatment  of  intracranial  lesions  with  highly  collimated  x-ray  beam.  Linac-based  radiosurgery  is  currently  performed  by  two  techniques:  couch or pedestal mounted. In the first technique, a device is required to affix patient's head to a couch  and  moreover  to  translate  it  accurately.  Structure  of  suc...

yarn tenacity is one of the most important properties in yarn production. this paper addresses modeling of yarn tenacity as well as optimally determining the amounts of the effective inputs to produce yarn with desired tenacity. the artificial neural network is used as a suitable structure for tenacity modeling of cotton yarn with 30 ne. as the first step for modeling, the empirical data is col...

Semi-Lagranging schemes have been explored by several authors recently for transport problems in particular for moving interfaces using level set method. We incorporate the backward error compensation method developed in [2] into the semi-Lagranging schemes with almost the same simplicity and three times the complexity of a first order semi-Lagranging scheme but improve the order of accuracy. W...

We show that any conservative scheme for solving scalar conservation laws in two space dimensions, which is total variation diminishing, is at most first-order accurate.

The hierarchical reconstruction [11] is applied to discontinuous Galerkin method on the two-dimensional unstructured grids. We explore a variety of limiter functions used in the construction of piecewise linear polynomials. We show that due to the abrupt shift of stencils, the use of center biased limiter functions is essential in order to recover the desired order of accuracy. Furthermore, we ...

Whereas actual attitudes represent people's evaluations of specific objects as being good or bad, desired the attitude positions that people wish they held. Previous work has established can have psychological consequences, but not yet tested extent to which predict change. In five datasets involving a variety populations and procedural variations, we explored how political moral factors motiva...

We propose a discretization scheme for a numerical solution of elliptic PDE’s, based on local representation of functions, by their Taylor polynomials (jets). This scheme utilizes jet calculus to provide a very high order of accuracy for a relatively small number of unknowns involved.
