论文摘要
储层计算是预测湍流的有力工具,其简单的架构具有处理大型系统的计算效率。然而,其实现通常需要完整的状态向量测量和系统非线性知识。我们使用非线性投影函数将系统测量扩展到高维空间,然后将其输入到储层中以获得预测。我们展示了这种储层计算网络在时空混沌系统上的应用,该系统模拟了湍流的若干特征。我们表明,使用径向基函数作为非线性投影器,即使只有部分观测并且不知道控制方程,也能稳健地捕捉复杂的系统非线性。最后,我们表明,当测量稀疏、不完整且带有噪声,甚至控制方程变得不准确时,我们的网络仍然可以产生相当准确的预测,从而为实际湍流系统的无模型预测铺平了道路。
The event questions men whether it is political, cultural or touristic. It has its own meaning as it starts something while showing a will, a new possibility to create, to meet and to surprise. The event is in fact an "advent that reaches everything" generally integrating itself into a long process or phase of the evolution of societies in terms of its societal structure. However, if the event exists, it is significant and therefore assessable. How to evaluate an Olympic Games or an international exhibition? Can we evaluate the before (from the statement of position, application file), the during (the course of the tourist, cultural or sporting event) and the after (the closing of the festival and its direct and indirect effects on society)? How then to evaluate all the dimensions of the event generally based on major tourist and urban planning operations? We will take as a field of study a city -- capital -- commercial port which has become a sort of archetype in the context of the organization of mega-events with a tourist vocation, such as the Universal or International Exhibitions and the Olympic Games, namely Barcelona and three very important dates for the Catalan capital: 1888, universal exhibition, 1929 universal and international exhibition, 1992 the modern Olympic Games and 2004 the Universal Forum of Cultures of Unesco, international exhibition. The economic interest of organizing an ephemeral giant event is still relevant and will be confirmed in the future with the role of Asian countries within the IOC and the BIE (Bureau international des expositions). The important thing is to develop a rational argument to communicate on the economic merits of the event. Sustainable development and Corporate Social Responsibility (CSR) are predominant elements for ephemeral events that are intended to be sustainable over time for future generations.
