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。
This article describes the study of a Bronze Age limestone slab with cup marks, discovered during the archaeological excavations of kurgan 1 of the kurgan grave field Prolom II, located in the Belogorsk region in Crimea. According to the results of the study, it is concluded that the Belogorsk slab is a sundial of about the XV - XII centuries BC and belongs to the Srubnaya culture. By type of sundial, it is closest to the analemmatic sundial. However, the principle of the hourly markings of the Belogorsk slab is so unique that it is proposed to separate this type of sundial into a new type - inverted analemmatic sundial. This type is characterized by the fact that, unlike typical analemmatic sundials, the gnomon remains motionless throughout the year, and in accordance with the analemma, the "dial" "moves" - an ellipse of hour markers from cup marks, i.e. gnomon and hour markers (cup marks) change places in terms of mobility. The movement of hour markers on the Belogorsk slab is not literal, but is imitated by several rows of cup marks, which are fragments of hour marker ellipses for different months of the year. The idea behind this type of sundial is so revolutionary that we can talk about the discovery of a completely new type of sundial, the analogue of which has not yet been discovered. Keywords: cup marks, sundial, inverted, analemma, true solar time, mean solar time, hour markers, Srubnaya culture, Bronze Age, kurgan grave field, slab.
