双Cox风险模型的破产概率

在假设保单的到达和理赔的发生都为Cox过程,而每份保单的价格和理赔额分别为独立同分布的随机序列时,得出了破产概率的上界,并在两Cox过程简化为两混合Poisson过程时,给出了最终破产概率的明确表达式和更明确的上界.

MODELING JUMPS IN RETURNS OF FINANCIAL ASSETS AS M4 PROCESSES： MEASURED EXCHANGE RATE EXPOSURE OF ASIAN EQUITY PORTFOLIO

1. Introduction An early analysis of exchange rate changes and share prices found that the general stock market index tended to move up (down) immediately after a devaluation (revaluation) of the local currency (Giddy 1974). It is surprising that previous researches (Jorion 1990; Amihud 1993; Bodnar and Gentry 1993) find that no contemporaneous relationship between exchange rate changes and excess equity market returns of largest U.S. exporting firms. Recently, it has argued that there is a…     

步进电动机起动过程中脉冲频率的优化控制

步进电动机在起动过程中，需要对其输入的脉冲频率进行控制，使其能准确定位且起动时间尽可能短．在分析步进电动机的矩频特性、系统的运动方程式的基础上，建立脉冲频率优化控制的数学模型、最佳起动频率的数学模型和最高运行频率的数学模型，并计算获得脉冲频率优化控制曲线．

A New Self-assembly Metal CMG Discriminator by Multi-exposure LiGA Like Process and Sacrificial Layer Process

The counter-meshing gears （CMG） discriminator is a mechanically coded lock, which is used to prevent the occurrence of High Consequence Events. This paper advanced a new kind of self-assembly metal CMG discriminator based on multi-exposure LiGA like process and sacrificial layer process. The new CMG discriminator has the following characters except low cost： 1） it has only discrimination teeth sections; 2） the thickness of each gear layer exceeds one hundred micrometers; 3） it is axially driven by a separate dectronic magnetic micromotor directly; 4） its CMG is made of metal and is batch fabricated in the assembled state; 5） it is prevented from rotating in the opposite direction by pawl/ratchet wheel mechanism; 6） it has simpler structure. This device has better strength and reliability in abnormal environment compared to the existing surface micro machining （SMM） discriminator.
