Grain size measurement using distribution classification
The concept of grain size distribution is important in many industrial processes. In this study, rolled chrome concentrate was investigated to find the average grain size. Distribution classification was used with covariance, gray level difference, LBP, Laws and color features. As a comparison cooccurrence features were used. Classification was performed by a distribution classifier using leave...

متن کاملDust Grain-Size Distributions From MRN to MEM
Employing the Maximum Entropy Method algorithm, we fit interstellar extinction measurements which span the wavelength range 0.125-3 μm. We present a uniform set of MEM model fits, all using the same grain materials, optical constants and abundance constraints. In addition, we are taking advantage of improved UV and IR data and better estimates of the gas-to-dust ratio. The model fits cover the ...
متن کاملGrain size measurement using magnetic and acoustic Barkhausen noise
Results on annealed nickel show that the total number of counts of both magnetic and acoustic Barkhausen signals vary inversely with grain size. In decarburized steels the total number of counts and the amplitude of both Barkhausen signals increase in proportion to grain size. The paper addresses these results in context of grain size, grain‐boundary segregation, and precipitate effect.
متن کاملExperimental Evidence for the Development of Bimodal Grain Size Distributions by the Nucleation-Limited Coarsening Mechanism
It has recently been hypothesized that transient bimodal grain size distributions can arise from unimodal distributions during coarsening if the continued growth of a majority fraction of the crystals is arrested by the energy barrier to nucleate new layers. To test this hypothesis experimentally, SrTiO3 has been coarsened in a titania-rich liquid at 15001C. Measurements of the grain size distr...
