Second-generation trapezoidal sheeting, characterised by longitudinal stiffeners in webs and flanges, is loaded near a support concentrated force bending moment. Currently, design codes predict related failure by: (a) determining the ultimate moment via effective width approach or Direct Strength Method (DSM); (b) finding web crippling load curve-fitted formula; (c) using an interaction rule to...

objective(s) ibuprofen is a problematic drug in tableting, and dissolution due to its poor solubility, hydrophobicity, and tendency to stick to surface. because of the bad compaction behavior ibuprofen has to be granulated usually before tableting. however, it would be more satisfactory to obtain directly during the crystallization step crystalline particles that can be directly compressed and ...

The computational method based on using the operational matrix of anorthogonal function for solving variational problems is computeroriented. In this approach, a truncated Hartley series together withthe operational matrix of integration and integration of the crossproduct of two cas vectors are used for finding the solution ofvariational problems. Two illustrative...

Efficient direct solvers based on the Chebyshev-Galerkin methods for second and fourth order equations are presented. They are based on appropriate base functions for the Galerkin formulation which lead to discrete systems with special structured matrices which can be efficiently inverted. Numerical results indicate that the direct solvers presented in this paper are significantly more accurate...

We present some efficient algorithms based on the Legendre-Galerkin approximations for the direct solution of the second and fourth order elliptic equations. The key to the efficiency of our algorithms is to construct appropriate base functions, which lead to systems with sparse matrices for the discrete variational formulations. The complexities of the algorithms are a small multiple of N oper...
