The article has described the reason why the “bounced beans” happened in high speed blanking and put forward some precautionary measures on “bounced beans” phenomenon.

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.

The approach and take-off technique is the most critical technical part in springboard diving.
