Hydrodynamic journal bearings are susceptible to static angular misalignment, resulting from improper assemblage, elastic and thermal distortion of the shaft and bearing housing, and also manufacturing errors. Several ...

The objective of this curricular integration work was the construction and implementation of a simulation module for the vibrational diagnosis of pulley misalignment and belt problems for the Technical Diagnosis and Energy ...

This curricular integration work had as objective to implement a simulation module for the study of the vibrational analysis of shaft misalignment for the rotor kit of the Technical Diagnostic and Energy Efficiency ...

For energetic atomic beams grazingly incident at the surface along the low index directions, fast motion parallel to the surface and slow motion perpendicular to the surface lead to the quantum diffraction pattern in the ...

Rotary machines are present in most industrial manufacturing processes. In this environment, predictive maintenance emerges as an important alternative for the detection of anomalies, promoting the intervention only when ...

Different methods for edge extraction have been studied in the past years. In a recent paper we have presented a rotation-invariant edge extractor based on a spiral phase filter placed in the frequency plane of a convergent ...

Recently, the growing demand for new technologies in telecommunications has generated much attention from the scientific community. The development of RF systems, the phenomenon of convergence services in a single device ...
