Modeling Trusted Computing

0 IntroductionThe purpose of trusted computingis to solve some of to-day’s security problems through hardware changes topersonal computer . The trusted property can be extendedfromroot of trust to entire PC platformthrough the chain oftrust[1].Root of trustis a small hardware device calledtrustedplatform module (TPM) addedto PC.A well-known project of trusted computing is trustedcomputing platformalliance(TCPA) .It is calledtrusted com-puting group (TCG) now[2 ,3]. Besides this , other…     

A Parallel Algorithm for the Convection Diffusion Problem

Based on the second-order compact upwind scheme, a group explicit method for solving the two-dimensional time-independent convection-dominated diffusion problem is developed. The stability of the group explicit method is proven strictly. The method has second-order accuracy and good stability. This explicit scheme can be used to solve all Reynolds number convection-dominated diffusion problems. A numerical test using a parallel computer shows high efficiency. The numerical results conform closely to the analytic solution.

供应链中准时采购的Stackelberg模型及决策

准时采购可有效缩短供应链整体响应周期,快速响应市场需求,实现供应链的运作。但在实践过程中,采购交付的准时性又成为供应链敏捷运作的瓶颈问题。从采购双方行为动机的角度出发,以有效的激励机制提高准时交货概率为目标,建立采购商为主方、供应商为从方的Stackelberg博弈模型;在模型的最优性分析基础上,讨论准时采购过程中采购商与供应商决策的交互影响关系;并在供应商完成采购订单所需的响应时间服从指数分布的假设下,分析采购商与供应商的最优策略及库存成本参数等对决策产生的影响。     

哲学视域中的和谐社会与其正义基础

构建和谐社会的基础在于全面实现社会正义,正义是社会和谐的保障,要实现社会正义,国家及政府的调节干预是一种积极的手段,法律则是一种强制力保障。

脂肪胺、醛、醇、醚的气相碱性与分子结构之间定量关系的研究

根据化学热力学原理和量子力学原理,发现脂肪胺、醛、醇、醚的气相碱性的大小主要取决于分子中亲核基团的特性和烷基基团上的氢原子数目和级数,据此提出了一种合理表征脂肪胺、醛、醇、醚的气相碱性与分子结构之间的定量关系式.对73种化合物气相碱性的计算结果表明,计算值与实验值的一致性令人满意,平均误差为0.508%.
