Emerging Technologies for Electric Power Generation Personnel Training
Considering that the trend in the workers’ training is the personalization and the use of technologies for self-learning; this article examines the role of emerging technologies and methodologies in the future of training of electric energy production human resources of Comisión Federal de Electricidad. We analyze the problem of complexity as an ingredient inherent in the activities of operation and maintenance of equipment for electricity generation.

A scanning probe microscope having a probe attachment fixture, to which a probe assembly is removably attached during measurements, driven in an engagement direction, and a sample stage driven in scanning directions perpendicular to the engagement direction includes a buffer with a number of buffer stations within the sample stage. When the stage is driven so that one of the buffer stations is in alignment with the attachment fixture, and when the attachment fixture is driven in the engagement direction to be in proximity to the buffer station, the probe assembly is selectively transferred in either direction between the attachment fixture and the buffer station. In a preferred embodiment, probe assemblies are transferred on transfer pallets, and a stationary magazine is provided for storing these pallets, which are transferred in either direction between the magazine and the buffer.
Review of Literature on Probability of Detection for Magnetic Particle Nondestructive Testing
Abstract : A critical review of the available literature concerning the minimum reliably detectable defect size aNDI for magnetic particle testing (MPT) in aerospace applications is presented. Four probability of detection (POD) studies relevant to detection of fatigue cracks in aircraft components were found over the period 1968 to 2011. As the statistical methods used in these four previous studies were either outdated or otherwise deficient, the original data were reanalysed using currently accepted techniques. A meta-analysis of the results is presented, with emphasis on statistical inferences for the defect size expected to be detected with 90% POD. It is shown that the minimum reliably detectable defect size aNDI = 2.0 mm currently specified by the Royal Australian Air Force for wet fluorescent magnetic particle inspection using the continuous method is consistent with estimates of the average performance of MPT derived from the reanalysis of the literature.
