摘要:
Emotion recognition from physiological signals has aroused great concern recently as its objective. In this paper, the recognition system from physiological signals is introduced, and important topics on emotion models, databases for analysis, feature extraction and selection methods, different classification techniques and performance issues are studied. Finally, the research challenges and trend of emotion recognition from physiological signals are discussed for future research.

摘要:
Research indicates that the combination of correct and erroneous examples has a positive effect on knowledge acquisition and transfer if learners have adequate prior knowledge. If only erroneous examples were provided, students with low prior knowledge may need additional supports so that their procedural skills can be effectively promoted. For this reason, this study, taking subtraction as the learning domain, conducted a 2 x 2 factorial design of quasi-experiment varying in example types (correct vs. erroneous examples) and feedback settings (with vs. without feedback). Results indicated that feedback may promote transfer and retention in learning from worked-out examples. However, there was no significant difference between correct and erroneous examples in helping students learn subtraction procedures. According to the results of our questionnaire on cognitive load, it was likely caused by the complexity of the organization and presentation of erroneous examples. We suggest that clear and intelligible presentation can be supported by computer technologies.

摘要:
This case study investigated mathematics teachers' perspectives and the status of the applications of information technology (IT) in a key senior high school in China. A questionnaire was conducted to collect data. This research focused on teachers' perceptions on the role of IT in mathematics classroom instruction, as well as the status of the technology integration in their class. Results of the data analysis indicated that there were no significant differences among mathematics teachers with variety from gender, age, years of teaching experience and education level towards the understanding on the development of IT and the application of IT in classroom instruction. In addition, some implications and suggestions were also provided in conclusion of this study.

Query-focused multi-document summarization;estimation of content-terms;scoring sentences
摘要:
Query-focused multi-document summarization aims to produce a summary in response to a user query. We present an approach based on estimation of content-terms to address this task. In the process of estimating content-terms, we make full use of the relevant feature and the information richness feature for assigning importance to each of them. With summary content-terms being identified correctly, the candidate sentences are ranked and best sentences are selected to form the summary. Experiments on DUC 2005 and 2006 are performed and the ROUGH evaluation results show that the proposed approach is encouraging.

摘要:
Service composition provides a flexible way to quickly enable new application functionalities in next generation networks. Composite services are turned to be more and more complex, and the performance analysis of composite service is an important issue for service providers who want to get better QoS. In this paper, we proposed a stochastic Petri net based approach for modeling Web service composition constructs and calculating the equivalent delay time of the composite Web service. Four basic constructs: sequence, concurrent, choice and loop constructs are mapped into Petri net. Methods to calculate equivalent delay time are illustrated in detail. A complex composite service can be reduced by repeatedly replacing basic constructs within it with equivalent single transition. This approach can be applied in performance analysis for complex composite Web service, as well as complex systems and workflow.

摘要:
There are many different e-learning system and educational resources, which have cause the problems, such as standard was not unified, resources was difficult to be shared, the supporting service need to be improved. The paper proposed an Educational Resources Public Service Platform based on Heterogeneous Data Exchange (ERPSP). ERPSP is an E-learning Resources Platform integrates all levels of educational resources by the one-stop operation pattern, and constructs the digital, integrated, and opening learning support service environment for different educational system and resources.

摘要:
针对移动自组织网络(Mobile Ad hoc Networks,MANET)的特点和IEEE802.11的链路层重传机制和分包策略的不足,研究基于广义误码率(Generalized Bit Error Ratio,GBER)和参考无线包重传概率(Packet Retransmission Ratio,PRR)的时延约束方程理论和传输层包长调整方法,并设计基于时延约束的MANET流媒体传输可变包长TCP友好速率控制机制(Variable Packet size TCP-Friendly Rate Control,VPTFRC).与其他方案不同,该机制进一步考虑了无线包重传概率对于包长调整和TCP友好速率控制机制的影响,给出了这一机制的理论模型与相关计算的详细说明,仿真试验的结果验证了该方法在有效吞吐量、传输延时及抖动和TCP友好性方面优于TFRC协议.
