Anomalous crystal structure of γ" phase in the Mg-RE-Zn(Ag) series alloys:Causality clarified by ab initio studyJunyuan Bai1,Xueyong Pang1,2,Xiangying Meng1,Hongbo Xie1,Hucheng Pan1,2,Yuping...) series alloys,has been extensively studied,and several structural models have been proposed in the past two decades.However,these reported models,and even the lattice constants at the same proposed......
characteristics of available parking spaces (APS). First, several APS time series were decomposed and reconstituted by the wavelet transform. Then, using an artificial neural network, the following five strategies for multi-step-ahead time series forecasting were used to forecast the reconstructed time series: recursive strategy, direct strategy, multi-input multi-output (MIMO) strategy, DIRMO......
