Abstract A high-power diode laser was used to generate single- and multi-bead coatings of Stellite™ 6 by coaxial cladding over flat grey cast iron (EN-GJLP-200) as a preliminary study develop wear corrosion resistant coating for brake disks on cost-effective substrate. In this article, we have focused detailed quantitative analysis the effect different powers (1.5, 2.0, 2.5, 3.0, 3.5, 4.0 kW) b...

the notion of a bead metric space is defined as a nice generalization of the uniformly convex normed space such as $cat(0)$ space, where the curvature is bounded from above by zero. in fact, the bead spaces themselves can be considered in particular as natural extensions of convex sets in uniformly convex spaces and normed bead spaces are identical with uniformly convex spaces. in this paper, w...

Abstract Additive manufacturing with steel opens up new possibilities for individual parts or complex supply chains. The direct energy deposition process DED-arc, also known as wire arc additive (WAAM), is particularly suited large structures a high degree of geometrical freedom. design freedom makes WAAM ideal creating force-flow-optimized nodes and spaceframes use in the construction industry...

When studying mathematics, many students consider mathematics to be a difficult subject because they see it as close system that prioritizes standards of rigor, speed, and memory. Conventional learning methods might make bored. Various model is needed overcome this. One which the culture associated with known ethnomathematics. The purpose this study was explore bead crafts Kenyah Dayak tribe, l...

Here we report the development of a fully integrated microfluidic chromatography system: A novel column geometry solves a long-standing problem in on-chip separations. This geometry facilitates the rapid and high yield stacking of multiple bead columns in poly(dimethylsiloxane) PDMS microfluidic devices using low pressure flow. Microcolumns are integrated with on-chip plumbing to enable fully a...
