Simultaneous Multithreading Fau Tolerance Processor

Transient fault detection mechanism is added to simultaneous muhithreading architecture. By exploiting both ILP (Instruction l~evel Parallelism) and TLP (Thread Level Parallelism), Simultaneous Multithreading(SMT) Fault Tolerance Processor can be expected to achieve better tradeoff between performance and hardware cost than traditional Fault Tolerance Processors. Detailed simulations of 3 of SPEC95 benchmarks show that executing two redundant programs on the fault-tolerant microarchitecture takes only 40%-61% longer than running a single version of the program. The new instruction fetch algorithm enhances the performance by 0. 4%～1% to most of the benchmarks we choose randomly.     

Hall Effect in Quasicrystals

The relations between Hall effect and symmetry are discussed for all 2- and 3-dimensional quasicrystals with crystallographical|y forbidden symmetries. The results show that the numbers of independent components of the Hall coefficient (R11) are one for 3-dimensional quasicrystals, two for those 2-dimensional quasicrystals whose symmetry group is non-Abelian, and three for those 2-dimensional quasicrystals whose symmetry group is Abelian. respectively. The quasicrysta[s with the same number of independent components have the same form of the components of R11.     

Hemoglobin Biocatalyst Polymerization of Aniline by UV-vis Spectraphotometry

A biocatalytic route for the synthesis of a water soluble and conducting complex of polyaniline (PAN1)/sodium dodecylsulfate (SDS) is presented. Hemoglobin is used in SDS anion surfactant . The polymerization proceeded quickly to result in a homogeneous emeraldine-colored dispersion of PANI. Absorption spectra of PANI/SDS in the aqueous dispersions at various pH values confirms that the reversibility of dedoping and redoping process of PANI/SDS and shows that the transition from emeraldine salt to emeraldine base form occurred at about pH 10.0-11.0 in this anionic micellar system. PANI/SDS in the organic solutions dedoped initially and redoped after 24h.     

软件工程知识的获取

本书是由新加坡世界科技出版公司出版的《软件工程与知识工程丛书》的第14卷。未来的软件系统将分布在整个网络上，并具有专门从事不同活动的代理。每一个代理都具有不同程度上的自治。软件开发机构将会依靠这些代理，利用不同的程序开发过程来生产软件程序。本书从遗传编程的角度讨论了具体的不同之处。作者试图通过设计一个用于演化程序的软件工程环境系统（SWEEP），来使我们对于开发多代理、多过程的未来的洞察力变得更为具体。SWEEP系统使用遗传编程在软件的创建与修改中起了中心的作用。此外，还对度量学特别注意，探索了可通用性、程序肿胀和有效程序长度问题。     

后基因知识发现中有选择的课题

大信息通过量序列与功能基因组技术绘制了人类基因序列图，并且使得大规模人类群体基因型与基因表达的特征勾画成为可能，进一步的研究是对基因组序列的准确注释、基因组与蛋白质之间相互作用和物种的遗传变异性上。基因组注释过程越来越以涉及进化研究和模型生物体的比较方法作为依据。DNA与蛋白质之间的相互作用是生物学相互作用中最基本的，而且在生物学、医学和药物学中具有普遍的意义。     

热带与亚热带环境地球化学

“第三届热带国家环境地球化学专题讨论会”1999年在巴西举行。来自22个国家的170位学者参加了会议，研究了若干与环境和经济相关的问题。本书将前三届会议的成果汇集在一起，介绍了有关过去10年内所累积的热带与亚热带环境地球化学知识。

针对传感器为时钟驱动、执行器、控制器均为事件驱动的一类非线性网络控制系统(net-worked control systems,NCS),通过在信息接收端设置一定长度的缓存,可以将时变的网络诱导时延转化为固定时延,并且将此类NCS建模为一类具有输入输出时延的非线性时延系统.基于建立的模型,利用Lyapunov定理和Razumikhin定理给出了系统渐近稳定的充分条件,同时给出使系统保持渐近稳定的最大允许网络诱导时延.最后通过算例验证了时延小于最大允许网络时延时,NCS是稳定的.     

Fabrication of PEDOT/PSS-ZnO nanowire by self-assembly method under vacuum condition

Poly(3,4-ethylenedioxythiophene) (PEDOT) has at- tracted much attention due to its high conductivity, excel- lent environmental stability and chemical processabil- ity[1,2]. PEDOT/PSS dispersion is a water-soluble system using poly(styrene sulfonic acid) (PSS) as the doping counterion during polymerization. The inclusion of PSS results in better solubility and processability to the PE- DOT/PSS aqueous dispersion[3, 4]. Recently, synthesis of one-dimensional (1D) multifunc- tional co…
