Auction houses employ in-house art experts to assess the value of objects. Items that will be placed on auction block are first published in catalogs with experts’ upper- and lower-bound estimates each object’s market value. This paper examines whether roundness those is related likelihood items sell their eventual hammer price. We find rounder lower reduce price perhaps also item sells. The up...

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 ...

This paper presents a new methodology to improve roundness process of the centreless grinding based on classic stability diagrams and relative rounding mechanism. study has shown that it is not always convenient have fixed setup angle. Based simulation results, suggested consider raw workpiece profile before selecting these parameters accordingly type error (odd or even lobed). It was found cha...

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...

Metrology applications commonly require non-contact, capacitive sensors for displacement measurements due to their nanometer resolution. In some metrology applications, for example, the measurement of roundness and spindle error motion, the displacements of stationary and rotating cylindrical artifacts are measured. Error from using a conventionally calibrated sensor with a non-flat (e.g., cyli...

The Triassic-Jurassic boundary (Tr-J; ∼201 Ma) is marked by a doubling in the concentration of atmospheric CO2, rising temperatures, and ecosystem instability. This appears to have been driven by a major perturbation in the global carbon cycle due to massive volcanism in the Central Atlantic Magmatic Province. It is hypothesized that this volcanism also likely delivered sulphur dioxide (SO2) to...
