Non-Noether Conserved Quantity of Poincaré-Chetaev Equations of a Generalized Classical Mechanics

In the present paper the Lie symmetrical non-Noether conserved quantity of the Poincaré-Chetaev equations of a generalized classical mechanics under the general infinitesimal transformations of Lie groups is discussed. First, we establish the determining equations of Lie symmetry of the equations. Second, the Lie symmetrical non-Noether conserved quantity of the equations is deduced. Finally, an example is given to illustrate the application of the results.     

空间参数曲线的双目标能量极小化方法及其应用

能量极小化方法已广泛用于平面曲线的构造,而在空间曲线构造方面的应用尚少。首先介绍了空间参数曲线的弯曲能和扭曲能,然后提出了一种以弯曲能和扭曲能同时极小为目标的空间参数曲线构造方法,最后以空间三次Bézier曲线为例,探讨了该方法在曲线的构造、延拓、平滑等问题中的应用。所提出的方法更符合空间参数曲线既需考虑弯曲又需考虑扭曲的特点。     

Potential Bounds in Nonpotential Two-Point Boundary - Value Problems

New conditions are suggested for the existence of solutions of two-point boundary -value problems. The situation is studied when monotone bounds of nonlinear terms do not guarantee the solvability of the problems. The approach developed is a combination of variational methods, simple fixed point principles, and methods of partially ordered spaces.

Two-point boundary value problems by the extended Adomian decomposition method

In this paper, we present an efficient numerical algorithm for solving two-point linear and nonlinear boundary value problems, which is based on the Adomian decomposition method (ADM), namely, the extended ADM (EADM). The proposed method is examined by comparing the results with other methods. Numerical results show that the proposed method is much more efficient and accurate than other methods with less computational work.
