Semi-Huber quadratic function and comparative study of some MRFs for Bayesian image restoration [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 The present work introduces an alternative method to deal with digital image restoration into a Bayesian framework, particularly, the use of a new half-quadratic function is proposed which performance is satisfactory compared with respect to some other ...

Reduction of total harmonic distortion in power inverters [PDF]
, 2005 The output voltage of PWM power inverters shows harmonic distortion due to several causes; the main ones are the modulation algorithm, nonlinearities in the output filter, dead times, voltage drops across the switches and modulation of the dc bus voltage.
