the assumptions considered in developing the saint-venant equations limit their application in many practical situations. the modified boussinesq equation was presented to overcome the limitation imposed by saint-venant equation due to the presence of non-hydrostatic pressure distribution and steep slope. in this paper a computational model was developed for solving the modified and the traditi...

The objectives of this project were to find novel genes that might be useful for optimising plant biomass to facilitate biofuel production. Since the phenolic polymer, lignin, surrounds and cross-links to other cell wall components, reducing the amount of lignin or altering its structure to make it easier to extract have become major targets for improving sugar release from plant biomass (sacch...

̄ Although a number of testing methods (Myers 1979) (Suwa, Scott, & Shortliffe 1982) (Nguyen et 1987) (Ould & Unwin 1987) (Tsai & Zualkernan 1990) (Gupta 1991) (Tsai, Zualkernan, & Kirani 1992a) have been proposed for testing expert systems, recent studies (Zualkernan, Tsai, & Kirani 1992) (Tsai, Sirani, & Zualkernan 1992b) (Tsai, rani, & Zualkernan 1993) suggest that conventional testing method...

fMany military leadership studies have related subordinates' perceptions of leader behavior to subjective (i.e., paper and pencil) measures of subcrdinate satisfaction and/or group effectiveness e.g., Halpin, 1954 (1); Reaser, Vaughan, and Kriner, 1974 (2); Bleda, Gitter, and D'Agostino, 1977 (3); O'Reilley and Roberts, 1978 (4). However, few studies have assessed the relationship between subur...

in this paper a modification of he's variational iteration method (vim) has been employed to solve dung and riccati equations. sometimes, it is not easy or even impossible, to obtain the first few iterations of vim, therefore, we suggest to approximate the integrand by using suitable expansions such as taylor or chebyshev expansions.

in this paper, modified simple equation method has been applied to ob-tain generalized solutions of burgers, huxley equations and combined forms of these equations. the new exact solutions of these equations have been obtained. it has been shown that the proposed method provides a very effective, and powerful mathematical tool for solving nonlinear partial differential equations.

Much of the previous work in developing analytical models for high performance composite materials has focused on representations of the heterogeneous medium as a homogenous, anisotropic continuum. The development of the equivalent properties of the homogenous medium from the geometry of the microstructure and the fiber and matrix properties has been come to be known as “micromechanics” (Daniel...
