Cigarette filter rods are a kind of easily deformed and irregularly shaped parts, the quality cigarette is often measured by rod roundness index, although they affected factors such as environment humidity, which can affect detection show blurred images. For image roundness, an improved active contour snake model algorithm proposed. The experimental results that in analysis iteration number on ...

Sound symbolism refers to associations between language sounds (i.e., phonemes) and perceptual and/or semantic features. One example is the maluma/takete effect: an association certain phonemes (e.g., /m/, /u/) roundness, others /k/, /ɪ/) spikiness. While this has been demonstrated in laboratory tasks with nonword stimuli, its presence existing spoken unknown. Here we examined whether effect at...

Apart from regular wheel wear such as decreasing wheel diameters and reduced flange thicknesses and heights, wheel flats (WF) and oval wheels (or OOR, Out-Of-Roundness) are the most common wheelset problems for railway vehicles. Within the FP7 Research Project “Saferail”, APT has developed an innovative wheelset monitoring system so-called “Wheel flat and Out of Roundness Monitoring (WORM) syst...
