A Secure Public-key Image Authentication Plan

Digital watermark can be used for image ownership verification or authentication. In this paper, we propose a new image authentication plan concentrating on its security performance. Digital watermark is first turbo coded, scaled and then processed in wavelet domain. To enhance security level, public key cryptosystem is utilized to replace traditional watermark key. Sinmlation results are finally given by experiment.     

Dispatch Liquidity Theory in a Deregulated Environment

Power system security and reliability are more complex issues in a deregulated environment.Various criteria have been considered for power system reliability. In the day-ahead market, a successful trade schedule should be able to accept various disturbances with sufficient flexibility to be adjusted during the re-dispatch process. This paper describes the dispatch liquidity theory and some liquidity indices. The liquidity indices evaluate the effective operating reserves with the network constraints taken into consideration. A model is presented to calculate the liquidity index. An extended trade scheduling model with minimum liquidity index constraints is presented that considers the distribution requirements of the operating reserves. The liquidity indices could also be used to coordinate the security and reliability between multistage markets and for contingency selection. The algorithms were tested with real power system data. The results show that the dispatch liquidity theory is reasonable and the algorithms are effective.

Microporous polymer electrolyte based on PVDF-PEO

Since Wright et al. found that the complex of PEO/alkali metals salt had the ability of ionic conductivity in 1973, in-depth studies have been carried out about various polymer electrolytes, which were applied to replacing the liquid electrolytes in lithium ion battery. At present, polymer electrolytes mainly include three kinds:     

明代士宦祝世禄与利玛窦交游述略

祝世禄乃明末南京陪都重要官员,西方传教士利玛窦在南京期间,曾得到他许多关照与帮助,在西方文献中多有反映,但在祝氏文集中仅有“赠利玛窦”一诗存世。考述祝世禄与利玛窦的交往,阐释祝世禄诗作的蕴意,从中可揭示当时部分知识分子对西学的态度。     

篮球运动训练对西安市中学生心理控制点发展影响的研究

本文运用文献资料法、问卷调查法和数理统计法,对西安市中学生篮球运动员和普通中学生进行了抽样研究得出:西安市中学生篮球运动员和普通中学生的心理控制点之间存在着显著差异;不同训练年限、不同技术等级的篮球运动员心理控制点也分别呈显著差异。一方面它为教练员、体育教师和运动员的归因训练提供了理论依据,另一方面也开拓了运动员的心理训练范畴。     

产朊假丝酵母(Candida utilis)尿酸酶的基本特性

涤纶长丝织物在染整加工中缩率的变化

涤纶织物在染整加工过程中，受到各种工艺条件的复合作用，从而使得产品在外部形态及结构尺寸上不断发生变化．为了确切反映染整加工中每道工序对织物形态的影响，实验模拟了不同品种的涤纶长丝织物的染整工艺，分别考察各工序处理后织物缩率的变化．结果发现，各个工序对织物的缩率有不同程度的影响，织物在整个染整工艺过程中的总缩率随着热定型温度的升高而增加;影响织物收缩的因素包括热、湿和碱，其中热、湿的作用最为显著．
