基于经验模态分解和离散小波能量特征的地毯织机噪声源识别

为识别和定位地毯织机主要噪声源,提出一种基于经验模态分解（EMD）和离散小波能量特征的地毯织机噪声源识别方法。首先应用EMD 对地毯织机噪声信号进行分解,获得若干本征模态分量,根据互相关系数剔除虚假分量并重构信号;其次使用ab 20小波对重构信号进行离散小波变换,分解得到各小波分量并计算各分量的能量 占比;然后提取能量占比较大的分量,分析其时频特性;最后采用激光测振仪依次测量地毯织机各主要部件的振动信号,对比分析得到主要噪声源所在位置,从而完成识别。研究结果表明,该方法可有效地识别和定位地毯织机主要噪声源。

The design and initial evaluation of visual cues in carpets to assist walking

Prior research has shown that carpets assist walking thereby reducing the incidence and injury severity of falls, and that visual cues can assist walking. However, little attention has been given to the ability of visual cues in carpets to assist walking. Design guidelines were developed for the colouring and patterning of carpet to provide visual cues to assist walking. The guidelines took into account age-related visual impairments, and were applied in the preparation of a carpet. The designed carpet was compared with two carpets of standard designs in an impaired walking trial. The trial subjects reported a significant preference for walking on the designed carpet, suggesting that appropriate design of carpets can increase their contribution to the well-being of older people and others with impaired walking.     

The effects of drying parameters and conditioning on mechanical properties of latex‐backed carpet

In this study, the effects of drying parameters and conditioning on the mechanical properties of latex‐backed carpet were investigated. Mechanical properties clearly correlated with the lowest moisture content (MC) experienced by samples in either drying or conditioning. Lowering MC was necessary to develop mechanical properties; however, the highest mechanical properties were achieved at the highest latex temperature, indicating that raising latex temperature can improve mechanical properties. The effect of conditioning on mechanical properties depended on the MC of the latex backing at the end of drying.     

基于小波能量的簇绒地毯跳纱疵点的检测方法

针对簇绒地毯中存在的跳纱类疵点提出了一种基于小波能量的疵点检测方法。该方法首先使用CCD相机对地毯图像进行采集,然后将采集到的地毯图像进行滤波处理,并用三层小波对其进行分解,通过提取分解得到的细节子图的能量值和正常地毯图像细节子图的能量值的比较来判断正在测试的图像中是否含有疵点;对于有疵点的地毯图像使用Otsu法进行阈值分割二值化,并进一步使用闭运算消除二值化图像中存在的噪点,突出疵点部分。最后通过实验验证了此方法的可行性,所提出的方法可以有效地将地毯图像中的跳纱类疵点检测出来。
