At low N, the media is a 1D array where all of the particles are in contact with, and are free to roll along, the inner wall of the drum. (R_COM R_drum). The stick-slip oscillations occur at a natural frequency of ω = (g/R_COM)^1/2. The stick and slip events are due ...
We experimentally and computationally study the dynamics of interacting oscillating Belousov–Zhabotinsky (BZ) droplets of 120 m diameter separated by perfluorinated oil and arranged in a one-dimensional array (1D). The coupling between BZ droplets is dominated by inhibition and is strongest at low co...

当我们使用sklearn进行fit或者predict等操作的时候,经常会遇到Expected 2D array, got 1D array instead一类的报错,其根本原因是因为最新的sklearn必须要传入一个二维矩阵所导致的,解决办法有如下三种。 一、numpy将行转成列 一行数据是一维数据,我们转成一列数...

In this paper, a magnetic detecting and sketching system utilizing a 1D magnetic sensor array with 56 magnetoelectric (ME) sensing units is proposed. The ME sensors used in this system are based on a (1‐1) connectivity Metglas/piezofiber composite operating in the longitudinally magnetized and ...
ValueError: Expected 2D array, got 1D array instead Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample. 在最新版本的sklearn中,所有的数据都应该是二维矩阵,哪怕它只是单独一行或一列,所以,要进行格式...
