Discussion of jumps catching capability of GARCH-Jump model;

A stochastic dynamic planning model with jump processes is presented for nonrenewable resources under two kinds of uncertainties.

In this paper,a new security pricing model—stochastic-volatility pricing model with jump and feedback—is proposed by considering the fact neglected by the traditional pricing models that important events frequently happen in the financial market.

Human-board interaction during a running takeoff in springboard diving;

The taking-off process in springboard diving motion is analyzed in this paper on the basis of mechanical model of diver/springboard system.

This paper analyses the technique of both approach and take-off on springboard diving,and primarily introduces the research of both methodological advancement and progeny,then makes elementary academic discussion on some biomechanical problem of springboard diving.
