水浴式灭菌柜停电处理方法的模拟验证

确定并建立最终灭菌的无菌制剂在灭菌过程中出现停电状况时的处理方法。采用在产品灭菌过程中人为断电进行模拟验证,结果发现:在停电时,通过采用后备电源给灭菌柜的监控系统提供不间断供电的方式,可使灭菌柜监控系统持续监控产品的灭菌状态并记录数据,并能够在一定时间内保持灭菌状态。验证得出结论:在正常生产过程中出现停电情况,通过采用后备电源给灭菌柜的监控系统提供不间断供电的方式,可使灭菌柜监控系统在外界停止供电的情况下,实现持续对正在灭菌的产品的状态监控、实时记录灭菌数据,并且不用将灭菌的控制模式由自动切换到手动,避免了F_0值的归零,从而使F_0值的计算得以延续。在保温和密封良好的情况下,在一定的时间范围内被灭菌产品能维持灭菌状态,并达到灭菌要求。

A costly state verification model with diversity of opinions

Summary. In simple models of borrowing and lending with ex-post asymmetric information, Gale and Hellwig (1985) and Williamson (1986) have shown that optimal debt contracts are simple debt contracts where borrowers repay a fixed interest rate whenever possible and lenders seize all the profit when borrowers default. In this note, we depart from their works by assuming that borrowers and lenders have heterogeneous beliefs, and show that simple debt contracts do not necessarily survive as optimal contracts.JEL Classification Numbers: G3, D8.     

公司环境报告:压力、鉴定和双重性影响

在公司股东以及政府部门、相关团体或组织、公众的压力下,国外越来越多的大公司在其会计年报或单独的环境报告中披露相关环境信息。目前,国外大多数公司对外公布环境报告和进行环境报告鉴定都是自愿的,且环境报告鉴定尚缺乏财务报表审计所具备的公认报告准则。环境报告及其鉴定会给公司带来许多有利影响和不利影响,对比双重性影响,可以揭示公司自愿实施环境报告及其鉴定的内在必要性。     

FDI对中国技术进步的贡献效应实证分析

外商直接投资(FDI)的经济效应问题一直是理论有多大贡献,学者们的研究结论还存在着较大的分歧.本文运用索洛测算技术进步的"余值"方法,选取中国1985年至2004年区间样本数据作为经济变量,从宏观角度分析了FDI对中国技术进步的影响效应.得出的结论是,引进FDI对促进中国的技术进步效果甚微,其原因和对策如何,需要认真研究.     

电子手写签名认证算法的研究

文章提出了在微机Windows环境中的一种联机电子手写签名认证算法。该算法在强调签名的形状和签名压力的动态特征上都具有相似性,并采用了基于特征函数的点—点手写签名匹配映射方法,先将联机输入的电子手写签名切分为笔段,以笔段作为签名的特征区,对两个待比较的签名相应笔段中的点,经由点—点的映射算法得到最后的匹配映射结果。     

NEWS-GENERATED DEPENDENCE AND OPTIMAL PORTFOLIOS FOR n STOCKS IN A MARKET OF BARNDORFF-NIELSEN AND SHEPHARD TYPE

We consider Merton's portfolio optimization problem in a Black and Scholes market with non-Gaussian stochastic volatility of Ornstein–Uhlenbeck type. The investor can trade in n stocks and a risk-free bond. We assume that the dependence between stocks lies in that they partly share the Ornstein–Uhlenbeck processes of the volatility. We refer to these as news processes, and interpret this as that dependence between stocks lies solely in their reactions to the same news. The model is primarily intended for assets that are dependent, but not too dependent, such as stocks from different branches of industry. We show that this dependence generates covariance, and give statistical methods for both the fitting and verification of the model to data. Using dynamic programming, we derive and verify explicit trading strategies and Feynman–Kac representations of the value function for power utility.

A secure,real-time stock market protocol

Stock markets constitute the largest electronic commerce market in the world. The tremendous growth in trading volume and the need for fast and accurate transaction execution has made the stock market one of the most technology friendly markets. The fastest growing stock exchange, NASDAQ, is a wholly electronic stock exchange with all transactions conducted over computer networks. However, the transaction model used by NASDAQ and other electronic stock markets still borrows heavily from the older traditional models used by non-electronic stock exchanges. Two important requirements of modern day stock market transactions are: (a) customer's ability to place sophisticated transaction orders to buy/sell stock, and (b) customer's ability to detect transaction delays. Modern electronic stock exchanges lack both the ability to place newer, more sophisticated transaction orders and the ability to detect delays in transaction execution. In this paper, we propose a protocol for stock market transaction that can model a new sophisticated model for transaction orders while continuing to support traditional transaction orders. The protocol is augmented with a mechanism to detect delays in transaction execution. It is further shown that the protocol proposed is secure, atomic, anonymous, private, and incurs low overhead costs.

大数据背景下保险人合同解除权的制度重构

大数据时代的技术进步深刻地改变着保险交易双方的信息力量对比,降低了保险人对投保人信息披露的依赖程度。保险法律制度面对技术进步带来的变革,需要合理配置保险交易注意义务的结构,加强保险人的信息核查义务,限制保险人合同解除权的滥用,以实现保险交易双方权利和法益的再平衡。
