In this paper, we introduce the analysis for gloss unevenness by using developed multiple directional incident lights optics. Gloss is strongly related to recognition of material texture. However, it looks different depending on angles, so has been difficult measure quantitatively. The caused surface roughness able analyze distribution normal surface. We have optical system that simultaneously ...

This two-part manuscript presents a comprehensive methodology for the irregularity assessment of urban stone pavements. The proper road surface using key performance indicators is necessary to plan appropriate maintenance strategies. However, there are no monitoring methods or evaluation criteria pavements whose surfaces more uneven than traditional ones due their structural characteristics. Th...

This article presents a comparative analysis of the properties cotton yarn spun on aerodynamic compact spinning and open-end rotor systems. Yarn samples with linear density 50 Tex, 37 30 25 20 Tex were both systems using same finisher drawn sliver medium staple which produced by specific mixing. The quality parameters such as mass variation, imperfection index, hairiness, tensile behavior (stre...
