This paper presents a novel back EMF detection method for sensorless BLDC motor drive systems. By this method, a true back EMF signal can be directly extracted for each phase without sensing the neutral point of the motor. The method proposed is not sensitive to switching noise and requires no filtering. Good motor performance is achieved over a wide speed(More)
The development and validation of alternative methods to animal testing is one of the major priorities for the cosmetic industry. These methods must be reproducible and predictive of the effect of cosmetics during normal use by the consumer. Among alternative methods recently proposed, those using reconstructed human epidermis kits are the most promising(More)
After a dominant role for more than 30 years, tamoxifen has been progressively replaced by aromatase inhibitors as adjuvant treatment for breast cancer in the menopaused woman.
