A investigação da prática de monitores em um observatório astronômico: subsídios para a formação
(Sociedade Brasileira de Física, 2018)
Abstract The present research is focused in the study about the training of monitors in communication of astronomy, having as main objective to point relevant elements to the training of monitors from an experience in a ...
A comparison between neutron-fluence measurements using metal-activation monitors and standard glasses calibrated via thin uranium-fission monitors and via ηq method
(2013-04-02)
The two fundamental approaches to fission-track dating involve either an explicit determination of the thermal neutron fluence (φ-method) or a calibration against age standards (ζ-method). The neutron fluence measurements ...
Influence of Excitation Signal on Impedance-based Structural Health Monitoring
(Sage Publications Ltd, 2010-09-01)
The electromechanical impedance (EMI) technique has been successfully used in structural health monitoring (SHM) systems on a wide variety of structures. The basic concept of this technique is to monitor the structural ...

Criminal recidivism after prison and electronic monitoring
(University of Chicago Press, 2013-02)
We study criminal recidivism in Argentina by focusing on the re-arrest rates of two groups: individuals released from prison and individuals released from electronic monitoring. Detainees are randomly assigned to judges, ...
A synthetic control chart for monitoring the process mean and variance
(2006-04-10)
Purpose - The aim of this paper is to present a synthetic chart based on the non-central chi-square statistic that is operationally simpler and more effective than the joint X̄ and R chart in detecting assignable cause(s). ...
Automatic system for thermal damage detection in manufacturing process with Internet monitoring
(2006-07-17)
This work involved the development of a smart system dedicated to surface burning detection in the grinding process through constant monitoring of the process by acoustic emission and electrical power signals. A program ...
Condition-based monitoring system for rolling element bearing using a generic multi-layer perceptron
(Sage Publications Ltd, 2015-12-01)
Rolling element bearings are critical mechanical components in rotating machinery and fault detection in the early stages of damage is important to prevent their malfunctioning and failure. Vibration monitoring is the most ...
