Mechanical impacts analysis in SAG mills due to small failures in the electric drive
(2014)
When the mechanical performance of the grinding process is analyzed, especially in terms of vibrations,
grinding efficiency, wear parts, lifespan of mills and lifters, etc. It is important not only to consider
structural ...
Keyboard navigation mechanisms in Tab Widgets: an investigation on ARIA’s conformance
(Association for Computing Machinery - ACMDongguk UniversityGyeongju, 2014-03)
This study presents an investigation on how keyboard accessibility has been delivered in RIA - Rich Internet Applications. We conducted an evaluation on 32 websites which contained Tab Widgets, from the 150 websites of ...
Screen printed barium titanate thick films prepared from mechanically activated powders
(2001-11-09)
Barium titanate thick films were prepared from mechanically activated powders based on BaCO 3 and TiO 2. The thick films were screen-printed on alumina substrates electroded with Ag/Pd. The BT films were sintered at 850°C ...
On the use of support mechanisms to perform experimental variables selection
(2020-01-01)
The selection of variables in a given experiment is crucial, since it is the theoretical foundation that guides how data should be collected and analyzed. However, selecting variables is an intricate activity, especially ...
High temperature mechanical behavior of plasma-nitrided inconel 625 superalloy
(2017-01-01)
INCONEL 625 nickel-based superalloys present limitations for use at temperatures above 600 °C. For this reason, protective coatings can be used as barriers to avoid both nucleation and crack propagation. The aim of this ...
On the Phase Transformation in Mechanically Alloyed Ni-Nb and Ni-Ta and Ni-Nb-Ta Powders
(Trans Tech Publications Ltd, 2012-01-01)
This paper reports on the phase transformation during the preparation of Ni-25Nb, Ni-25Ta, Ni-20Nb-5Ta and Ni-15Nb-10Ta (at-%) powders by high-energy ball milling from elemental powders. The milling process was performed ...
Towards security mechanisms for an industrial microservice-oriented architecture
(2021-08-15)
Service and Microservice-oriented architectures (MOA) are being applied in different areas including Industry 4.0 and Industrial Internet of Things. Even though there are many advantages of using MOA in industrial applications, ...
A multiaxial fatigue damage model for isotropic materials
(2020-01-01)
This paper presents a novel damage mechanics based failure model enabling the prediction of low cycle fatigue life and residual strength of isotropic structures under multiaxial loading. The approach herein proposed does ...
Design Of Al-nb2al Composites Through Powder Metallurgy
