Sensor-weapon-target assignment based on improved SWT-opt algorithm 基于改进SWT-opt算法的传感器武器目标分配
Li Zi-fen, Li Xiang-min, Dai Jin-jin, Chen Jin-zhu, Zhang Feng-xia
Sensor-weapon-target assignment is an important activity involved in planning and executing a course-of-action in a future warfare. The outcome of networked targeting and attacking based on C4KISR may strongly depend on the intelligent usage of available sensors and weapons maximizing their effectiveness. One downside of Swt-opt algorithm is that it highly depends on perfect network topologies. In this paper, consensus algorithm is combined with Swt-opt algorithm to guarantee the assignment effective over many different dynamic network topologies. The improved algorithm also has advantages over communication, computation and robustness to inconsistent situation awareness. The feasibility of the improved algorithm is proved at the end of the paper.
在未来战争中,传感器-武器-目标分配是规划和执行作战方案的重要环节。基于C4KISR的网络化目标和攻击的结果可能在很大程度上取决于可用传感器和武器的智能使用,最大限度地提高其有效性。Swt-opt算法的一个缺点是它高度依赖于完美的网络拓扑。本文将共识算法与Swt-opt算法相结合,保证了在多种动态网络拓扑下的有效分配。改进算法在通信、计算和对不一致态势感知的鲁棒性方面也具有优势。最后,对改进算法的可行性进行了验证。

Mengquan Tan, Shijian Zhu, Jia-shan Jin
System fault process can be cut off if failures can be fined in time after they occurred. But there must be enough time for failures can be detected. And the process time is longer; the higher probability fault process can be cut off. Failures considered in traditional event tree method are simplified as 0 or 1 (abnormal or normal) condition. But in dynamic reliability study, failures are not just considered as logic state of system. Failure parameters and subsequent failures would inference system course and its final condition. Extend event tree based dynamic reliability analysis method is studied in this paper. System dynamic characteristics after failures are considered in this method. And a simple system is analyzed in this paper. Analyzing results shown that, this method is effective in analyzing system dynamic reliability.

Scalable time definite integration in parallel computing 并行计算中的可伸缩时间定积分
Yue Hu, W. Tong, Xiaoli Zhi, Huailiang Xuan
In parallel computing, the memory requirement is an important problem, and in parallel software development, it is vital to optimize the memory management strategy. Programmers need to know the memory optimizing degree. But, the parallel programs' performance evaluation metric speedup only refers to computing time, without considering the memory cost when executing programs. In this paper, the relationship between computing time and memory requirement is expressed by a formula, with which the influence of memory requirement in parallel computing can be calculated. The experiment results demonstrate that the scalable time definite integration proposed in this paper, can properly predict parallel computing time under certain parallel system size, and also could reflect the operating environment's working capacity.
在并行计算中,内存需求是一个重要的问题,而在并行软件开发中,优化内存管理策略至关重要。程序员需要知道内存优化程度。但是,并行程序的性能评价指标加速率仅指计算时间,没有考虑程序执行时的内存成本。本文将计算时间与内存需求之间的关系用公式表示,利用公式可以计算出内存需求对并行计算的影响。实验结果表明,本文提出的可扩展时间定积分能较好地预测一定并行系统规模下的并行计算时间,并能反映运行环境的工作能力。

Research on participation behavior of users in internet-based innovation community: An empirical investigation 基于互联网的创新社区中用户参与行为的实证研究
Shan-nung Chu
Internet-based users innovation community can be defined as mediated social spaces in digital environment that allow groups to form and be sustained primarily through ongoing communication processes. The members of innovation communities are usually lead users of specific kind of products, they put up web sites or participate in the existent one hosted by manufacturers or the third part for the purpose of benefiting from group innovation actions. The members have common interest on product innovations and sharing innovative ideas with each other, even build up online or offline personal relationships. Focusing on the internet-based user innovation community, this paper put forward a theoretical based on the the self-concept-based motivation model to explain the customer's participation behavior in the user innovation community. Using the Structural Equation Modeling (SEM) method, data analysis showed that all of the research hypotheses were supported. Based on our analysis, we can find out that users will participate in the internet-based innovation community when they perceive this as a channel to gain happiness, demonstrate their ability level, and attain the feeling of belonging to.
基于互联网的用户创新社区可以被定义为数字环境中的中介社会空间,它允许群体主要通过持续的交流过程形成和维持。创新社区的成员通常是特定产品的主要用户,他们建立网站或参与由制造商或第三方主办的现有网站,以从群体创新活动中获益。成员们对产品创新有着共同的兴趣,彼此分享创新的想法,甚至建立线上或线下的个人关系。本文以基于互联网的用户创新社区为研究对象,提出了一种基于自我概念的动机模型来解释用户创新社区中用户参与行为。采用结构方程建模(SEM)方法对数据进行分析,结果表明所有的研究假设都得到了支持。通过我们的分析,我们可以发现,当用户将互联网创新社区视为获得快乐、展示能力水平和获得归属感的渠道时,他们会参与到互联网创新社区中。

The role of the arc erosion in sever wear of carbon strip/copper contact wire in pantograph-catenry system 电弧侵蚀在受电弓-接触网系统碳带/铜接触线严重磨损中的作用
T. Ding, G. Chen, S. Xiao, L. Xie, Q. Zeng
Experimental tests on friction and wear behavior of copper contact line/carbon strip were carried out under the conditions of different electric current on a pin-on-disc tester. During testing, the coefficient of friction and wear rate were recorded and arc discharge phenomenon was observed. The result indicated that friction coefficient decrease with increase of electric current intensity due to the lubrication role of electric current. As the electric current increased, wear volume distinctly increased due arc discharge ablation. By analysis of SEM micrograph and EDX spectrum on wear surface of carbon strip, it is known that arc erosion, oxidative wear and metal melting are dominant with electric current and abrasive wear and adhesive wear are dominant without electric current.
在针盘式试验机上对铜接触线/碳带在不同电流条件下的摩擦磨损性能进行了试验研究。测试过程中记录了摩擦系数和磨损率,并观察了电弧放电现象。结果表明,由于电流的润滑作用,摩擦系数随电流强度的增大而减小。随着电流的增大,由于电弧放电烧蚀,磨损量明显增大。通过对碳带磨损表面的SEM显微照片和EDX光谱分析可知,有电流时以电弧侵蚀、氧化磨损和金属熔化为主,无电流时以磨粒磨损和粘着磨损为主。
