With rising interest in additive manufacturing (AM) techniques, there is an increased focus on research that evaluates critical parameters that guide the selection of powders that are suitable for AM. One such parameter is a powder’s spreadability, d... see more

A combination of an improved analytical model for the description of particle motion on the spinning disc and hodographic ballistics in the air was described earlier. The unified model (Gindert-Kele, 2006) is considered nearly exact for single particles l... see more

This work presents a meta-analysis that compares the suitability of various parameters used to characterize wettability in tribological systems. It also examines the relationship between wettability and the friction factor for multiple lubricant-surface p... see more

The tribology of lubricated poly(ether ether ketone) (PEEK)—steel tribosystems was investigated in the static and boundary friction regime. Pentaerythrite ester and trimellitic acid ester were used as lubricants. The lubricants differed in their molecular... see more

Three-dimensional (3D) multi-input-multi-output (MIMO) is one of the enabling technologies for next-generation mobile communication. As the elevation angle in the 3D MIMO channel model might vary against the height of the base station (BS) antenna, it sho... see more

Sound backscattered to a sonar from a seabed decreases in intensity with increasing range ( R ) due to geometrical spreading. As a far-range approximation, a geometrical spreading correction of + 30 log R decibels may be applied. A correct... see more

Wetting phenomena plays a crucial role in a wide range of technological applications. Spreading of liquids on solids involving phase change is encountered in many areas ranging from biological systems to industrial applications such as coatings, printing,... see more
