人类科学中的新极限论（I）   总被引：1，自引：1，他引：0  

欧阳耿 《喀什师范学院学报》2008,29(6):28-32

从新构建的基础理论学的角度,在无穷观及与之密切相关的数量体系的理论框架中讨论人类科学中长期被忽视的现有极限论的基础问题,得到“经典无穷理论体系基础理论中的本质性缺陷决定了人类不可能在经典无穷理论体系的框架中构建科学的极限论,而新无穷观和与之密切相关的新数谱的产生为极限论的体系性和基础理论奠定了新的、牢固的基础,决定了新极限论的产生”的明确结论．  相似文献

Historical and probabilistic structural analysis of the Royal ditch aqueduct in the Alhambra (Granada)     

《Journal of Cultural Heritage》2014,15(5):499-510

The structural and historical analysis of the aqueduct of the Alhambra is presented. In the 13th century, Muhammad I built the palatial city of the Alhambra. To provide a water supply, Muhammad I built an irrigation ditch, known as the Royal ditch. The aqueduct was reconstructed in the 18th century in ashlar masonry to replace the original one. This work analyzes the history, geometric modeling, materials and stability of the aqueduct. Due to difficulties in testing and measuring the properties and loads, the Monte Carlo analysis technique is used to analyze stability, where the input parameters are defined as probabilistic distributions. Monte Carlo analysis provides the probability of risk of collapse defined by the geometric security coefficient obtained by means of the theory of limit analysis. Additionally, this technique is used to optimize the thickness of the arch.  相似文献
