摘要：穴位理疗可以有效治疗老年人退行性疾病和慢性疾病,但由于医护人员数量少、培养周期长、理疗器械普及率低等问题,便携式穴位理疗服务难以惠及所有患者。针对上述问题,设计并制作了一款具有智能触觉感知功能的软体理疗执行器,分析其弯曲特性;搭建实验平台;通过向该软体理疗执行器内通入气压周期性变化的压缩空气,驱动该软体理疗执行器实现其穴位理疗功能;嵌入触觉感知传感器,设计基于低通滤波的数据采样算法,实现其脉搏检测功能。通过实验验证了软体理疗执行器穴位理疗和脉搏检测功能的有效性,证明软体理疗执行器可以安全有效地与老年人交互,在智慧养老领域具有广泛应用前景。

摘要：目的针对现有图像修复方法不能很好地实现结构和纹理信息之间的双向交互,在修复缺失面积较大或纹理复杂的图像时存在纹理模糊、结构失真等问题。方法提出了一种基于双向坐标注意融合模块和傅里叶特征聚合模块的二阶段网络图像修复方法。首先,使用结构编-解码器和纹理编-解码器对受损图像进行结构重建和纹理合成,产生初步的修复结果;然后,将粗修复结果输入到细化修复网络,利用双向坐标注意融合模块和傅里叶特征聚合模块对图像内部纹理细节进行修复;为增强全局一致性,设计了双向坐标注意融合模块来实现结构和纹理信息之间的双向交互,并设计了傅里叶特征聚合模块,用于捕获全局上下文信息,增强图像局部特征之间的相关性,以获得精细的修复结果;此外,还利用双流判别器来估计结构和纹理的特征统计量,以区分原始图像和生成图像。结果在CelebA-HQ数据集上进行实验,与4种图像修复方法进行比较,定性结果表明方法生成的人脸图像更加清晰自然;定量结果表明方法在峰值信噪比、结构相似性指数和弗雷歇距离上均优于对比算法;对模型中各模块的消融实验结果也验证了所提出创新点的有效性。结论因此,所提出的方法能够有效地修复受损的人脸图像,特别是在大面积遮挡下也能生成具有结构合理、纹理清晰的图像。

摘要：本文通过博弈方法分析了分销渠道中上游制造商的定向广告策略与下游零售商的定向定价策略之间的相互关系,研究发现:定向广告不仅可以节约广告成本,还能帮助制造商攫取更多的渠道利润,但这将损害零售商的利益;零售商可以通过定向定价策略诱使制造商放弃定向广告,但也有可能因此被剥夺更多的利润空间;即便如此,零售商仍有可能采取损害自身利益的定向定价策略,这是两害相权取其轻的结果。
