"Abgegebene" und "gültige abgegebene" Stimmen     

Bernd-Christian Funk 《Zeitschrift für Hochschulrecht, Hochschulmanagement und Hochschulpolitik: zfhr》2007,6(1):4-7

Pr?sident/Pr?sidentin, Vizepr?sident/Vizepr?sidentin und die beiden Sekret?re/Sekret?rinnen bilden das Pr?sidium der ?sterreichischen Akademie der Wissenschaften. Ihre Wahl bedarf der Best?tigung durch den Bundespr?sidenten. Der Wahlvorgang ist durch die Satzung und die Gesch?ftsordnung der Akademie geregelt. Unklarheiten im Gefüge der Wahlrechtsbestimmungen k?nnen die Operabilit?t beeintr?chtigen und Anschlusskonflikte über die Gültigkeit von Wahlen zur Folge haben. Die Best?tigung durch den Bundespr?sidenten hat keine Kontrollfunktion. Sie ist ein symbolischer Rest ehemaliger monarchischer Interventionsvorbehalte. Heute unterstreicht sie den hohen Stellenwert und das Ansehen, das die Akademie der Wissenschaften und ihre Autonomie haben. Die Folgen einer fehlerhaften Wahl werden durch die Best?tigung des Bundespr?sidenten nicht geheilt.  相似文献

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     

杨善升  陆文聪  纪晓波  陈念贻 《上海大学学报(英文版)》2006,10(4):366-370

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.  相似文献   

Too Much,Too Young? An Analysis of the Key Stage 3 National Literacy Strategy in Practice   总被引：1，自引：0，他引：1  

Neil Allen 《English in Education》2002,36(1):5-15

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.  相似文献   

通过串音预测对PCB布线的3W规则进行验证     

莫付江 《天中学刊》2003,18(2):30-33

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．  相似文献   

Pattern design on 3D triangular garment surfaces     

WANG Jin LU Guo-dong LI Ji-tuo CHEN Long ZHANG Dong-liang 《浙江大学学报(A卷英文版)》2007,8(10):1642-1649

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.  相似文献   

Numerical Calculation of Concrete Slab Response to Blast Loading     

ZHOU Xiaoqing HAO Hong KUZNETSOV Valerian A WASCHL John 《天津大学学报(英文版)》2006,12(B09):94-99

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.  相似文献
