Many practical problems in commerce and industry involve finding the best way to allocate scarce resources a-mong competing activities. This paper focuses on the problem of integer programming, and describes an evolutionary soft a-gent model to solve it. In proposed model, agent is composed of three components: goal, environment and behavior. Experimental shows the model has the characters of parallel computing and goal driving.

Improving Electricity-Producing Performance of a Microbial Fuel Cell by Applying Magnetic Field

中国科学院地质与地球物理研究所第11届（2.11年度）学术年会

Shear and compressional velocity structures and features of the D" discontinuity near the core-mantle boundary(CMB) beneath eastern Eurasia are studied based on forward waveform modeling and differential -travel-time analysis of ScSH-SH,sScS-sS,PcP-P and pPcP-pP ***-quality differential-travel-time analysis reveals two high-velocity patches spanning a width of 3000 km and separated by a 300-km wide normal velocity *** maximum shear and compressional velocity perturbations reach 3.8%and 2.7%,*** data indicate that the D" discontinuity emerges in the high velocity patches and disappears in the normal-velocity ***,the features of the D" discontinuity,although constrained by rather sparse seismic data,vary from diffusive discontinuities in the eastern patch to sharp discontinuities in the western *** D" discontinuities occur at about 2.0 km above the CMB in the eastern patch with a shear velocity jump of 3.0-5.0%and a transitional depth of at least 100 km,and at 2.0 km above the CMB in the western patch with an abrupt shear velocity jump of 5.0%.A diffusive P wave discontinuity is also observed in the eastern patch with the similar features of the S wave *** inferred features of the D" discontinuity can be explained by the post-perovskite transformation in the lower *** observations that the D" discontinuities occur only in the high-velocity patches may be due to the effect of the positive Clapeyron slope of the post-perovskite transition,and the varying transitional depths of the D" discontinuity in the high-velocity regions may be caused by the compositional effects on the post-perovskite transition in the presence of strong variations of composition within the high-velocity *** high-velocity patches geographically correlate with the subduction of the Pacific and Indian plates in the past 30-60 Ma,and the normal-velocity gap falls into the subduction gap between the Pacific and Indian plates

An Adaptive Control-based Feedback Load-shedding Strategy

运用多元统计分析法综合评价广东烟草工业经济效益

2.07年国际电子商务、工程及科学领域的分布式计算和应用学术研讨会

作者： Lin Ouyang1, Qingping Guo1, Qin Zhou2. Qiumei Pu1 1School of Computer science and technology, Wuhan {2. of technology Wuhan, Hubei 430063 china 2.5} of Electrical Engineering, Shanghai Dian Ji {2. Shanghai 2.02.0 china

There is a large class of applications that produce high-frequency data continuously in 7 days per week and 2. hours per day. The traditional data processing system can’t deal with them efficiently because of the active data pushing and the passive queries. With the purpose of dealing with these data, data stream management systems (DSMS) appeared. For the geographical distribution of data streams, distributed data stream processing systems are studied recently. As an important aspect of distributed data stream management system (DDSMS), load management can balance system load incurred by unpredictable incoming data stream and inappropriate query operators’ distribution. Load-shedding acts as an important role in load management of distributed data stream system. In this paper, a control-based feedback load-shedding strategy is proposed to degrade system load. Compared with previous work which concentrates on one metric factor only, it takes four metric factors, such as CPU usage ratio, memory utilization, average length of waiting data queue and data tuple delay, into account to increase system stability and to decrease the loss of query accuracy.

并行调试对并行程序开发非常重要,然而传统的远程并行调试方式是采用登录(telnet)命令通过命令行的文本界面进行,非常繁杂。本文介绍了为曙光3000系统设计实现的远程并行调试器RPB(Remote Parallel Debugger)。RPB实现了完全并行调试等功能,并且具备图形用户界面,用户界面采用Java语言和Swing工具包实现,具备平台独立的特点。RPB采用客户端/服务器模式,客户端和服务器之间的通信采用当今流行的CORBA中间件技术。RPB支持通过局域网或广域网远程调试并行机上的程序,屏蔽了客户平台的差异和并行机地理位置上的差异,因而大大提高了并行机的好用性。

研究了碱金属离子(Li^+、Na^+、K^+、Cs^+)和碱土金属离子(Ca^(2.)、Sr^(2.)、Ba^(2.))为助剂的硫化MoO_3/ZrO_2.化剂上CO加氢合成低碳混合醇的反应性能。碱金属离子(Li^+,K^+)、特别是钾离子为助剂的催化剂比之碱土金属离子助剂具有更好的合成低碳醇的活性和选择性。从一系列的实验和分析发现,硫化K-MoO_3/ZrO_2.合成低碳醇的活性和选择性强烈依赖于钾助剂的含量和反应条件。合理选择最佳K/Mo比(～0.5原子比)、反应压力、温度和空速可以获得较好的合成醇活性和选择性。

人们一直在为制备聚合物宏观单晶体而努力探索着。多少年来,所制得的聚合物都是非晶或半晶的。50年代Keller从稀溶液(<0.01％)中培养得了微米量级的聚乙烯晶片,是一个重大的突破,随后几乎所有能结晶的聚合物都得到类似的晶片,它们具有垂直于晶片的折叠链结构,链的折叠部分破坏了晶体的三维有序,晶体结构并不完整。因此聚乙烯等晶片的出现仍然不是聚合物宏观单晶体,甚至由于结晶性聚合物的折叠链结构是如此地普遍,在一个时期里竟认为不存在完整的聚合物单晶。
