At the same time the changing length of the chromosome with the splicing operator and the interruption operator can guarantee the multiplicity of the chromosome,and avoid the genetic algorithm falling into the most superior party.

Then, the nonlinear bending of a saturated poroelastic cantilever beam with fixed end impermeable and free end permeable,subjected to a suddenly applied constant concentrated transverse load at its free end,was examined with the Galerkin truncation method.

Based on the mathematical model for large deflection of saturated poroelastic beam,the dynamical behavior of simply supported saturated poroelastic beam with two permeable ends,subjected to a suddenly applied transversal constant load or a harmonic load,was investigated with Galerkin truncation method.

Longitudinal vibration equation which governs a pipeline laying in 3000 meters underwater under construction in the case of untouched seabed is established and solved by Galerkin truncation method.

This article first gives a brief introduction to a truncation method for computing one dimension and two dimension transforms with applications to image processing, then emphasizes the parallel implementation on MPP dawn1000 using the blocked method according to the characteristic of image operation.

Considering the physical features and computing requirements of in-water profile spectral data,the cut-off point method is adopted to identify the outliers in in-water profile spectral data,and is compared with the other two common methods(the triple standard difference method,ratio method proposed in ProSoft software).
