Analysis and Calculation of No-Load EFM Waveform for Powerformer

2009 Asia-Pacific Power and Energy Engineering Conference, 2009
The field circuit coupling time-stepping FEM is proposed to calculate the no-load EMF waveform of salient pole machine, according to the Powerformer prototype, the no-load EFM waveform of Powerformer is calculated, and the effects of different damper windings constraints are considered during calculation, and then the results are compared with the ...

Feature Fusion Based Face Recognition Using EFM

2004
This paper presents a fusing feature Fisher classifier (F3C) approach for face recognition, which is robust to moderate changes of illumination, pose and facial expression. In the F3C framework, a face image is first divided into smaller sub-images and then the discrete cosine transform (DCT) technique is applied to the whole face image and some sub ...

EFM and ESD in photolithography by cavity QED

Fourtieth IAS Annual Meeting. Conference Record of the 2005 Industry Applications Conference, 2005., 2005
Sub-micron gaps in photolithography are known to undergo electrostatic discharge (ESD) under applied voltage or fields. Recently, reticle failure caused by electric field migration (EFM) of metallic ions has surfaced as a serious problem. Under fields induced from production equipment, the glass substrate between electrodes is coated with metal cations
