    Stable Routh-Padé-type approximation in model reduction of interval systems

    GU Chuan-qingYANG Jian
    369-373页
    查看更多>>摘要:An interval Padé-type approximation is introduced and then Routh-Padé-type method (IRPTM) is presented to model reduction in interval systems. The denominator in reduced model is obtained from the stable Routh table, and its numerator is constructed by the interval Padé-type definition. Compared to the existing Routh-Padé method, IRPTM does not need to solve linear interval equations. Hence, we do not have to compute interval division in the process. Moreover, theoretical analysis shows that IRPTM has smaller computational cost than that of Routh-Padé method. A typical numerical example is given to illustrate our method.

    查看更多>>摘要:Several equivalent statements of generalized subconvexlike set-valued map are established in ordered linear spaces. Using vector closure, we introduce Benson proper efficient solution of vector optimization problem. Under the assumption of generalized subconvexlikeness, scalarization, multiplier and saddle point theorems are obtained in the sense of Benson proper efficiency.

    Axisymmetric solutions of the Chaplygin gas for initial negative radial velocity

    查看更多>>摘要:In this paper, a three-parameter family of self-similar and weak solutions are constructed rigorously in two space dimensions for all positive time to the Euler equations with axisymmetric and radial negative initial velocity for the Chaplygin gas. Under the axisymmetry and self-similar assumptions, the equations are reduced to a system of three ordinary differential equations, from which we obtain structures of solutions besides their existence. The solutions exhibit some phenomena, such as formation and evolution of black hole, expansion and explosive expansion, in the evolution of universe.

    Aggregate gradation design of asphalt mixture with stone-to-stone contact based on fuller's model

    查看更多>>摘要:Based on Fuller's model, a gradation design is presented for the load-carrying capacity of an asphalt mixture with stone-to-stone contact. The coarse aggregate gradation, fine aggregate and filler gradation are respectively designed for their different effects on an asphalt mixture with stone-to-stone contact. The equation of coarse aggregate gradation is deduced from the Fuller's model. Fine aggregate gradation is calculated by using Fuller's equation. The asphalt mixture with the 16 mm maximum size of aggregate is verified. When the coefficient of coarse aggregate gradation is 0.35 and fine aggregate gradation is 0.25, the volume parameters of asphalt mixture meet the technical specifications. Moreover, the high temperature stability and crack resistance at low temperature are all well.
