摘要：
Driver behavior recognition is crucial for traffic safety in intelligent transportation systems. To understand the driver distraction behavior, deep learning methods has been used to learn the hierarchical features of receptive field images. However, most of existing studies focus on investing in spatial components based on the convolutional neural network for visual analysis. In this study, an attention-based deep neural network (ADNet) method is proposed for driver behavior recognition. The ADNet framework is first presented, which integrates the lightweight attention block into the deep learning model to strengthen the representative power of the model. Then, the channel attention (CA) block is designed to model inter-channel dependencies in the ADNet. Furthermore, the spatial attention block is combined with the CA for adaptive feature extraction. Data augmentation is used in the data preprocessing stage to improve recognition performance. The effectiveness of the proposed method is verified on the distraction dataset of American University in Cairo (AUC) and the real dataset of Hunan University (HNU). The ADNet method achieves a Top-1 accuracy of 98.48%, which outperforms the state-of-the-art methods. © 2022 Elsevier B.V.

摘要：
A set of Ni doping Fe–Ga ribbons were fabricated using melt spinning method. The microstructure was studied using extended X-ray absorption fine structure spectroscopy (EXAFS), high resolution X-ray diffraction (HRXRD) and metallurgical microscope. The results of microstructure indicated that as Ni concentration increased, the lattice matrix transformed from body-centred cubic (bcc) to face-centred cubic (fcc), with the decrease of unit cell volume and the emergence of little amount B2 and E21 phase. The result of magnetic and magnetostrictive properties showed that the saturation magnetization decreased with Ni doping. (110) texture in studied ribbons resulted in low saturation magnetic field and high saturation magnetostrction. In addition, small amount of precipitated phase E21 improved the magnetostricion of FeNiGa ribbons. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

摘要：
Perovskite manganite La0.5Ba0.5MnO3 (LBMO) films were deposited on (001)-oriented single-crystal SrTiO3 (STO) substrates by pulsed laser deposition. High-resolution X-ray diffraction and grazing incidence X-ray diffraction techniques were applied to characterize the crystal structure and lattice strain of LBMO films. The in-plane and out-of-plane growth orientations of LBMO films with respect to substrate surface have been studied. The epitaxial orientation relationship LBMO (001) [100] //STO (001) [100] exists at the LBMO/STO interface. The lattice strain of LBMO film begins to relax with the thickness of LBMO film up to 12nm. When the thickness is further increased up to 43nm, the film is in fully strain-relaxed state. Jahn–Teller strain plays an important role in LBMO/STO system. The mechanism for strain relaxation is in accordance with that of tetragonal distortion. © 2017, Springer-Verlag Berlin Heidelberg.

摘要：
[Pr0.7Sr0.3MnO3/La0.5Ca0.5MnO3]20 superlattices were epitaxially fabricated on (001) MgO substrates with 24nm La0.5Ca0.5MnO3 (LCMO) buffer layer by pulsed laser deposition. As the thickness of Pr0.7Sr0.3MnO3 (PSMO) layer and LCMO layer is not identical, non-uniformity in the superlattice period thickness will occur and result in lower metal–insulator transition temperature and larger magnetoresistance (MR) at a wide low-temperature range. Furthermore, the percolation model was used to quantitatively understand the transport mechanism of superlattice. Our research results demonstrate that inhomogeneous layer thickness accompanied with charge ordering phase separation can strongly influence the transport properties of superlattice. Enhanced magnetoresistance at a wide temperature range provides possibilities for practical application in manganite-based film devices. © 2017, Springer Science+Business Media New York.

摘要：
This essay will give the definition for attributes reduction of the incomplete decision table based on the discernibility object pair set. Through the proof of rough theory of incomplete definitions and simple properties, the attribute reduction of the positive region by using the definition and the attribute reduction of incomplete decision table are the same, and we can say that the complexity is reduced. Examples show that attributes reduction algorithm based on incomplete decisions is more rational. © Springer-Verlag Berlin Heidelberg 2014.

摘要：
This document calculates and discusses circular groove angle (CGA) affects on journal bearing performance. CFD method has been used for calculate N-S equations and cavitation effect has been considered. The results show that as CGA increases, the maximum pressure is decreased; the capacity and friction moment are also decreased. The maximum pressure position is increased from 1 to 2 when CGA is 180°. This paper will provide a theoretical basis for journal bearing groove optimal design. © 2013 Springer-Verlag.
