The Element free Galerkin method, which is based on the Moving Least Squares approximation, requires only nodal data and no element connectivity, and therefore is more ̄exible than the conventional ®nite element method. Direct imposition of essential boundary conditions for the element free Galerkin (EFG) method is always dif®cult because the shape functions from the Moving Least Squares approx...

Let G be a group hyperbolic relative to a finite collection of subgroups P. Let F be the family of subgroups consisting of all the conjugates of subgroups in P, all their subgroups, and all finite subgroups. Then there is a cocompact model for EFG. This result was known in the torsion-free case. In the presence of torsion, a new approach was necessary. Our method is to exploit the notion of dis...

Kropholler and Mislin conjectured that groups acting admissibly on a finite-dimensional G-CW-complex with finite stabilisers admit a finitedimensional model for EFG, the classifying space for proper actions. This conjecture is known to hold for groups with bounded torsion. In this note we consider a large class of groups U containing the above and many known examples with unbounded torsion. We ...

this article deals with the buckling analysis of perfectly bonded cross-ply laminated composite plates reinforced by wavy carbon nanotubes (cnts) under in-plane loads using element free galerkin (efg) method based on first-order shear deformation theory (fsdt). the wavy single-walled cnts and poly-co-vinylene are used for the fibers and the matrix, respectively. the cnt fibers are distributed i...

While the Mössbauer spectrum of a magnetically ordered powder sample can be used to determine the direction of the local hyperfine field (Bhf) in the coordinate system defined by the electric field gradient (efg) tensor, the spectrum of an oriented single-crystal provides a direct measurement of the angle between the absorbed or emitted γ and Bhf, primarily through the observed line intensities...

Ab initio Hartree-Fock molecular orbital calculations were applied to the crystalline imidazole and its derivatives in order to examine systematically the effect of possible N–H·· ·N type hydrogen bonding on the nuclear quadrupole interaction parameters in these materials. The nitrogen quadrupole coupling constant (QCC) and the asymmetry parameter ( ) of the electric field gradient (EFG) were f...

The 35C1 NQR spin-lattice relaxation mechanism in isomorphous N i(H 20 ) 6SnCl6 and M g(H20 ) 6SnCl6 crystals is reported. The spin-lattice relaxation time T1(j in the Ni compound is determined mainly by a paramagnetic relaxation. However, above ca. 400 K T1Q decreased rapidly and a log vs. T 1 curve was almost linear. This steep decrease of T1Q was explained by reorientational motions of the a...

System testing of a GUI-based application requires that test cases, consisting of sequences of user actions/events, be executed and the software’s output be verified. To enable automated re-testing, such test cases are increasingly being coded as low-level test scripts, to be replayed automatically using test harnesses. Whenever the GUI changes—widgets get moved around, windows get merged—some ...

The NMR spectra of molecular hydrogen isotopologs dissolved and orientationally ordered in nematic liquid-crystal solvents provide a wealth of information. Because they are quantum rotors, the various isotopologs H2, D2, T2, HD, HT, and DT have different order parameters, with larger internuclear distance having smaller order parameter. The signs and magnitudes of the order parameters are liqui...
