Reflectance and Related Studies of The Weathering of Surface Coatings
… internal reflection spectroscopy and surface roughness measurement, with their respective data being correlated as far as possible. The actual coatings materials examined in this way comprise, in the first part, a range of commercial paints chosen to represent a cross-section of those …

Experimental modelling of surface roughness and dynamic friction coefficient of diamond like carbon coated shafts
… products with DLC often have strict surface roughness and friction coefficient goals. This research investigates the surface roughness and friction coefficient properties of uncoated and DLC coated specimens in an effort to satisfy two particular requirements of the industry. The first …

Use of smartphones to measure pavement roughness across multiple vehicle types at different speeds
Measuring pavement roughness has been an important practice for transportation agencies for many years now. Commonly, this measurement is recorded as International Roughness Index (IRI) and is collected via a data collection vehicle (DCV) using a combination of lasers, accelerometers, and a …

Acoustic monitoring of hydraulic resistance in partially full pipes.
… losses in sewer pipes are caused by wall roughness, blockages and in-pipe sedimentation. Hydraulic resistance is a key parameter that is used to account for the hydraulic energy losses and predict the sewer system propensity to flood. Unfortunately, there are no objective methods to …

Modelling the dynamic interactions of rolling bearings
… machine that would be capture in its housing. Measurements in operation conditions are made for comparisons with cylindrical and spherical rolling bearings. This approach shows that a deeper insight in the understanding of machine vibration can be gained when one tries to model sources and …
