针对基于深度学习的图像超分辨率重建算法大多侧重于从大量外部训练数据中学习,而忽视图像本身的内部知识以及过于关注局部特征的问题,提出一种基于类金字塔图残差网络的图像超分辨率重建算法.首先,该算法构建的残差图卷积结构利用一种预生成图结构的方式将提取的特征图转换为预生成图结构的顶点来构成图结构数据,从而通过图卷积来学习特征自身内部的拓扑结构,同时使用残差学习适度地加深图卷积网络以提高重建性能;其次,该算法构建的类金字塔多空洞卷积结构,通过充分利用不同大小的感受野,避免了不能完全覆盖所有像素点的缺陷,更好地融合不同尺度的特征信息;最后,经过大量实验验证,所提出的算法显著优于主流超分辨率方法,有着更好的客观和主观度量结果.

在中文拼写纠错任务中,字符在文本中的距离信息和顺序信息是重要的特征,因此位置编码至关重要。传统的位置编码无法区分字符的前后联系,此外二阶段方式的纠错方案存在错误传播问题。针对上述问题,提出一种多任务学习下融合位置编码的中文拼写纠错方法,使用融合位置编码更好地为模型提供位置信息;使用多任务学习机制缓解错误传播问题,提升模型泛化能力。针对公开数据集进行实验,实验结果在F1值方面有稳定提升,验证了所提方法的有效性。

Shimmy can reduce the service life of the nose landing gear, affect ride comfort, and even cause fuselage damage leading to aircraft crashes. Taking a light aircraft as the research object, the torsional freedom of landing gear around strut axis and lateral deformation of tire are considered. Since the landing gear shimmy is a nonlinear system, a nonlinear mechanical model of the front landing gear shimmy is established. Sobol index method is proposed to analyze the influence of structural parameters on the stability region of the nose landing gear, and Routh-Huritz criterion is used to verify the reliability of the analysis results of Sobol index method. We analyse the effect of torsional stiffness of strut, caster length, rated initial tire inflation pressure, rake angle, and vertical force on the stability region of theront landing gear. And the research shows that the optimization of the torsional stiffness of the strut and the caster length of the nose landing gear should be emphasized, and the influence of vertical force on the stability region of the nose landing gear should be paid attention to.
