支持向量分类算法在5-HT3受体拮抗剂的构效关系研究中的应用

In this work, support vector classification （SVC） algorithm was used to build structure-activity relationship （SAR） model of the 5-hydroxytryptamine type 3 （5-HT3 ） receptor antagonists with 26 compounds. In a benchmark test, SVC was compared with several techniques of machine learning currently used in the field. The prediction performance of the model was discussed on the basis of the leave-one-out cross-validation. The results show that the accuracy of prediction of SVC model was higher than those of back propagation artificial neural network （BP ANN）, K-nearest neighbor （KNN） and Fisher methods.     

中国需要真正的创业教育——基于“挑战杯”全国大学生创业计划竞赛的分析

“挑战杯”全国大学生创业计划竞赛引发的大学生创业热潮及其争论受到越来越多的关注。这些争论反映了创业计划竞赛存在的问题乃至中国高等教育的弊端,即应试性教育与功利性竞赛、精英化教育与理想化竞赛、学生对科研参与度低与竞赛作品学院气浓、高校科研的封闭性与企业对竞赛参与的冷漠性。必须加大改革力度,构建真正意义上的创业教育体系:走出竞赛功利化的误区;创新人才培养理念;解构人才的“被格式化”;打破“以赛代学”模式,构建创业教育“立交桥”。

Too Much,Too Young? An Analysis of the Key Stage 3 National Literacy Strategy in Practice

This article was first drafted after I worked for 14 weeks last year in a school that was piloting the National Literacy Strategy at Key Stage 3. I now work in another school delivering the full published Strategy to Year 7. In this article, I explore the contradictions inherent in the Strategy in attempting to develop the English and literacy skills of Key Stage 3 pupils. Ultimately, my argument is that the educational benefits of this teaching to objectives is at odds with some of the deeper aims of the Strategy and of English teaching, and that the constant assessment involved puts too much pressure on our youngsters at an age when they should be concentrating on social development as people.     

通过串音预测对PCB布线的3W规则进行验证

在传输线理论的基础上，利用有限元(FEM)法计算分层介质中微带线上场的分布，并通过SPICE仿真对其等效电路在不同频率电源激励下产生的串音进行预测．预测结果验证了印制电路板布线遵从“3W”规则的重要性．由此得出结论：3W规则的使用有功于PCB设计满足EMC系统设计标准，并最大限度地减小印制线之间的耦合．     

Pattern design on 3D triangular garment surfaces

This paper focuses on a pattern design method for a 3D triangular garment surface. Firstly, some definitions of 3D style lines are proposed for designing the boundaries of patterns as drawing straight lines or splines on the triangular surface. Additionally some commonly used style lines are automatically generated to enhance design efficiency. Secondly, after style lines are preprocessed, a searching method is presented for quickly obtaining the boundaries and patches of a pattern on the 3D trian- gular surface. Finally a new pattern design reuse method is introduced by encoding/decoding the style line information. After style lines are encoded, the pattern design information can be saved in a pattern template and when decoding this template on a new garment surface, it automates the pattern generation for made-to-measure apparel products.

Numerical Calculation of Concrete Slab Response to Blast Loading

In the present paper, a dynamic plastic damage model for concrete has been employed to estimate responses of a reinforced concrete slab subjected to blast loading. The interaction between the blast wave and the concrete slab is considered in 3D simulation. In the first stage, the initial detonation and blast wave propagation is modelled in 2D simulation before the blast wave reaches the concrete slab, then the results obtained from 2D calculation are remapped to a 3D model. The calculated blast load is compared with that obtained from TM5-1300. Numerical results of the concrete slab response are compared with the explosive test carried out-in the Weapons System Division, Defence Science and Technology Organisation, Department of Defence, Australia.
