Using he spirit of VaR technique and base on the income of risk about insurer and the yield of initial reserve is constant or random,the pricing and initial reserve of equity-linked life insurance are discussed,the result of simulation is gave.

Pricing and Initial Reserve of Equity-linked Life Insurance with Minimum Guarantee;

The aim of this article is to explore into a system and quantificational method that supports the initial spares.

In view of this present condition,a method is discussed to calculate the quantities of initial spares whose life follow exponential distribution,normal distribution and Weibull distribution,and to calculate the quantities of follow on spares which are repairable and irrepairable.

Application of adaptive Kalman filter in initial alignment of SINS on stationary base;

Application of Gaussian mixture particle filter in initial alignment for strapdown inertial navigation system on stationary base;

Neural network based INS initial alignment for ground-to-ground missiles;

Application of extended particle filter in INS non-linear alignment;

Application of Unscented Kalman Filter for Large Misalignment Errors in INS Alignment;

In this paper,a simplified method of analyzing the observability of INS is studied at first,then based on the simplified model,a fast estimation method of the azimuth error is creatively proposed for the initial alignment of INS on stationary base,the time of initial alignment is reduced greatly.
