Nonlinear analysis of pile foundation jacket platform

In this paper, the nonlinear collapse of the BOHAI-8 pile foundation jacket platform has been analyzed. The ultimate load and collapse process of two computational models of the structure are given. One model is of fixed support whose length is eight times the pile leg diameter and the other considers the nonlinearity of the soil-pile interaction.

GOTOBLAS一般矩阵乘法高效实现机制的研究

对GOTOBLAS库(GOTO)的实现机制,尤其是其中的一般矩阵乘法部分的实现进行了分析.结合近年来的一些研究成果,讨论了如何高效地实现矩阵相乘操作,把存储层次对程序性能的影响提高到计算模型的高度.对比实验表明,GOTO库的性能远远高于没有考虑存储层次的一般BLAS库.证明了GOTO库性能上的优越性和将存储层次引入计算模型的必要性.

QUANTITATIVE STRUCTURE-ACTIVITY-RELATIONSHIPS FOR TOXICITY OF PHENOLS USING REGRESSION-ANALYSIS AND COMPUTATIONAL NEURAL NETWORKS

Quantitative structure-toxicity models were developed that directly link the molecular structures of a et of 50 alkYlated and/or halogenated phenols with their polar narcosis toxicity, expressed as the negative logarithm of the IGC50 (50% growth inhibitor
