MIS新思维软件工具的设计与实现

本文针对目前陈旧的管理软件的设计方法提出了一种新的观点,同时探讨了为实现这种新观点而研制的软件工具的设计方法和实现技巧。     

一类泛圈图

本文证明了如果G是2连通无爪图,G不是圈,n=|v(G)|>q,G的每个导出子图A都满足φ(a_1,a_2),且G中不存在W′作为其导出子图,则G是泛圈图。     

L3 L~＋L~－γγ事例的一种可能解释

本文用ＴＣ（Ｔｅｃｈｎｉｃｏｌｏｒ）模型，解释了Ｌ３Ｌ￣＋Ｌ￣－γγ事例，具体分析发现四个Ｌ３事例可以由过程ｚ→ρ°ρ°→Ｌ￣＋Ｌ￣－Ｐ°（γγ）产生。

An ERP study for the degrees of the difficulty in visual search

The present study mainly probed the relationships between ERP components and the degrees of difficulty in visual search. Three experimental and one controlled conditions were randomly selected. Results showed that the P1, N1, and P2 amplitudes and latencies had no significant differences among the three experimental and one controlled conditions, and the ERP waveforms of low perceptual load of visual search were different from that of high perceptual load. These results might indicate that the latencies and amplitudes of initial P1, N1 and P2 in high and low perceptual load conditions were almost the same. The ERP waveforms of parallel search were very different from that of serial search, and the ERP waveforms of serial search were very similar. The P3 amplitudes increased as the degrees of the difficulty in visual search decreased.     

Web-Based Information Extraction Technology

Information extraction techniques on the Web are the current research hotspot. Now many information extraction techniques based on different principles have appeared and have different capabilities. We classify the existing information extraction techniques by the principle of information extraction and analyze the methods and principles of semantic information adding, schema defining,rule expression, semantic items locating and object locating in the approaches. Based on the above survey and analysis,several open problems are discussed.
