A Parallel Genetic Simulated Annealing Hybrid Algorithm for Task Scheduling

0 IntroductionGrid computingis a hot topic inthe current internet research,and a developing direction of the parallel and distributedprocess[1 ,2].Since the task scheduling in grid computing faces aNP-hard problem[3];it has drawn attention from many scholarsand become the focusinthe field of the current grid computing re-search.In recent years , two global random and opti mal algorithmhave been widelystudiedandappliedinthefield of the gridcompu-ting research: GA(Genetic Algorithm) and SA( …     

Merkle Tree Digital Signature and Trusted Computing Platform

0 IntroductionDigital signatureis a key technique to provide datainteg-rity andsource authenticationcapabilities to enhance da-ta trustworthiness in trusted computing platform. Most cur-rent digital signature schemes are based on complex mathe-matical problems , such as integer factoring, discrete log-arithm,and discrete logarithm on elliptic curves . The hard-ness of these underlying mathematical problems is really un-certain at present . Merkle treeis a method used for authenti-cation and di…     

Improvement of Identity-Based Threshold Proxy Signature Scheme with Known Signers

0 IntroductionIdentity-based (ID-based) cryptography[1]is rapidly emer-gingin recent years .The concept of the proxy signature scheme was first in-troduced by Mamboet al[2]in 1996 .The concept of thresholdproxy signature was proposed[3 ,4]. Apractical and secure (t,n) threshold proxy signature scheme should satisfy the secre-cy,the proxy protected,the unforgeability,the non-repudia-tion,the ti me constraint ,andthe known signers[5].In 2006 , Baoet al[6]proposed an ID-based thresholdproxy si…

地方高校干部人事管理制度创新的综合思考

位于非省会中心城市且经济欠发达地区的地方高校要提升自身的竞争力，必须坚持以干部人事管理制度创新为先导，不断推进内部管理制度创新。在推进干部人事管理制度创新过程中，一是要进一步更新管理观念，营造创新环境；二是要加强对改革中难点问题的分析与研究，剖析其制度缺陷，明确创新的方向；三是要注重机制建设，建立良性循环的运行机制。     

基于MCMC算法的贝叶斯面板单位根检验

针对面板单位根检验存在检验势不稳定和原假设设置主观选择的问题,提出基于面板数据分位自回归模型,选择非对称Laplace分布的似然函数对模型进行贝叶斯分位回归分析.结合参数的完全条件分布设计MCMC抽样算法,进行贝叶斯分位单位根检验,并利用Monte Carlo模拟实验研究了贝叶斯分位单位根检验的有效性与可行性.研究结果表明,基于面板数据分位自回归模型的贝叶斯单位根检验方法解决了检验势不稳定以及原假设主观设置的问题,能够给出更全面稳健的单位根检验判断.
