Bursts are electrical spikes firing with a high frequency,which are the most important property in synaptic plasticity and information processing in the central nervous system. However,bursts are difficult to identify because bursting activities or patterns vary with phys-iological conditions or external stimuli. In this paper,a simple method automatically to detect bursts in spike trains is described. This method auto-adaptively sets a parameter (mean inter-spike interval) according to intrinsic properties of the detected burst spike trains,without any arbitrary choices or any operator judgment. When the mean value of several successive inter-spike intervals is not larger than the parameter,a burst is identified. By this method,bursts can be automatically extracted from different bursting patterns of cultured neurons on multi-electrode arrays,as accurately as by visual inspection. Furthermore,significant changes of burst variables caused by electrical stimulus have been found in spontaneous activity of neuronal network. These suggest that the mean inter-spike interval method is robust for detecting changes in burst patterns and characteristics induced by environmental alterations.

无监督学习是解决未知雷达辐射源信号识别的有效方法。Support Vector Clustering(SVC)是一种基于支持向量机的无监督聚类方法。SVC不仅时间复杂度高,而且在处理分布复杂、不均匀样本时,识别率较低。结合K-均值与SVC的优点,提出一种基于K-均值的SVC无监督聚类方法。此方法用K-均值聚类法对数据样本作初步的线性划分,将原数据样本划分成若干子样本。再将这些子样本分别映射到高维特征空间,用SVC方法去处理非线性问题。由K-均值聚类法将二次规划问题分解,大大减少SVC的计算量,降低时间消耗。相对于原数据样本,子样本的分布较为简单、均匀,容易找到更为合适的SVC参数值。对雷达辐射源信号进行聚类分析的实验结果表明,此方法处理速度较快,识别率较高。

武汉理工大学学报 2006年第S1期28卷 376-380页

作者： CHEN Yong,LIN Feilong,WANG Xiao,TANG Kefeng (college of Mechanical & electrical {2.,Zhejiang university of Technology,Hangzhou 310032.china) college of Mechanical & electrical {2. Zhejiang University of TechnologyHangzhou 310032China

In this paper,the multi-agent model about shop logistics is set up. This model has 8 agents: raw materials stock agent,process agent,testing agent,transition agent,production information agent,scheduling agent,process agent and stock agent. The scheduling agent has three subagents: manager agent (MA),resource agent (RA) and part agent (PA). MA,PA and RA are communicating equally that guarantees agility of the whole MAS system. The part tasks pass between MA,RA and PA as an integer,which can guarantee the consistency of the data. We use a detailed example about shop logistics scheduling in a semiconductor company to explain the principle. In this example,we use two scheduling strategies: FCFS and SPT. The result data indicates that the average flow time and lingering ratio are changed using different strategy. It is proves that the multi-agent scheduling is useful.

作者：金华征程浩忠 Department of electrical engineering Shanghai Jiaotong University

Because connection number can express and process synthetic uncertainties caused by various uncertainties in the transmission network planning, a connection number model (CNM) was presented to compare the values of connection number logically. This paper proposed a novel model for transmission network flexible planning with uncertainty. In the proposed planning model both certainty and uncertainty information were included, and the cost-benefit analysis method was used to evaluate the candidate schemes in the objective function. Its good adaptability and flexibility were illustrated through two examples.
