Enhancing Surface Topology of Udimet®720 Superalloy through Ultrasonic Vibration-Assisted Ball Burnishing

open access: yesMetals, 2020
This contribution reports the effects of an ultrasonic-vibration assisted ball burnishing process on the topological descriptors of nickel-based alloy Udimet®720. This material is of high interest for the transportation industry, and specifically for the

Topology change and context dependence [PDF]

open access: yes, 1999
The nonclassical features of quantum mechanics are reproduced using models constructed with a classical theory-general relativity. The inability to define complete initial data consistently and independently of future measurements, nonlocality, and the ...

On the topology of global coronal magnetic fields [PDF]

open access: yes, 2014
This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

FRACTAL STRUCTURE OF TITANIUM NITRITE DEPOSITED ON STAINLESS STEEL SUBSTRATE

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2014
On the basis of images obtained using scanning tunneling microscope, it was shown that the fractal dimension can be considered as some universal surface characteristic of the titanium nitrite, deposited on stainless steel.

Tracking surfaces with evolving topology [PDF]

open access: yesACM Transactions on Graphics, 2012
We present a method for recovering a temporally coherent, deforming triangle mesh with arbitrarily changing topology from an incoherent sequence of static closed surfaces. We solve this problem using the surface geometry alone, without any prior information like surface templates or velocity fields.

Topology Analysis of Bicycle Rim Brake Pad to Improve Braking Performance

open access: yesMATEC Web of Conferences, 2018
Various parameters of rubber brake pad tribology will affect the braking performance of a rim brake system of a bicycle. Out of those, three main parameters are contact length of brake pad, surface topology of friction surface, and the thickness of rim ...
