In this article, several advanced connected transformations from mathematical morphology for computational neuroanat-omy applications are developed. In particular, brain is separated from the skull in MRI T 1 using morphological connected openings. The use of connected transformations allow the preservation of regions, without introduce new information. As(More)
A New Adaptive Self-Tuning Fourier Coefficients Algorithm for Periodic Torque Ripple Minimization in Permanent Magnet Synchronous Motors (PMSM) Torque ripple occurs in Permanent Magnet Synchronous Motors (PMSMs) due to the non-sinusoidal flux density distribution around the air-gap and variable magnetic reluctance of the air-gap due to the stator slots(More)
Photothermal techniques allow the detection of characteristics of material without invading it. Researchers have developed hardware for some specific Phase and Amplitude detection (Lock-In Function) applications, eliminating space and unnecessary electronic functions, among others. This work shows the development of a Digital Lock-In Amplifier based on a(More)
A composition of the viscous opening and the lower leveling is introduced to extract brain in magnetic resonance imaging T1. The innovative transformation disconnects chained components and has better control on the reconstruction process of the marker inside of the original image. However, the sequential operator requires setting several parameters, making(More)
Three-phase induction motor drive requires high accuracy in high performance processes in industrial applications. Field oriented control, which is one of the most employed control schemes for induction motors, bases its function on the electrical parameter estimation coming from the motor. These parameters make an electrical machine driver work improperly,(More)
This paper describes an analysis method for achieving control torque and speed with vector control for induction motors. An indirect field-oriented output feedback motor controller is presented; it is suitable for low-cost applications. A current model control is used to sense back electromotive force (back-EMF) by means of an analog to digital converter(More)
The Brushless Direct Current (BLDC) motor has advantages like high efficiency and torque, low electromagnetic interference and maintenance, this make it suitable for low power applications, however, the addition of an electronically switching driver induces problems with power quality standards in a PI closed-loop based on Hall effect sensors.
