Estimating vocal fold contact pressure from raw laryngeal high-speed videoendoscopy using a Hertz contact model
(MDPI AG, 2019)
The development of trauma-induced lesions of the vocal folds (VFs) has been linked to a high collision pressure on the VF surface. However, there are no direct methods for the clinical assessment of VF collision, thus ...
MEASUREMENT OF FLAME SPEED IN COPPER CONCENTRATE CLOUDS
(Sociedad Chilena de Química, 2006)
Servocontrole de velocidade aplicado a motores de indução monofásicos sem sensores mecânicos
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2008-10-31)
This work proposes a sensorless speed control applied to single-phase induction motors
(SPIM). The objective is to present an alternative for variable speed single-phase motor
drives for residencial applications, which ...
Estimating Vocal Fold Contact Pressure from Raw Laryngeal High-Speed Videoendoscopy Using a Hertz Contact Model
(2019)
Featured Application A method to directly estimate the contact pressure of the vocal folds using uncalibrated laryngeal kinematic data is presented. The approach is promising in enhancing the objective assessment of vocal ...
Measurement of flame speed in copper concentrate clouds
(SOC CHILENA QUIMICA, 2006)
More than 50% of the world primary copper is produced by Flash Smelting technology [1], which partially burns copper concentrate particles. It has proved to be superior to other processes because of its low fuel consumption, ...
Controle de velocidade sensorless de motores brushless DC submetidos a variações periódicas de carga
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2011-07-21)
This master thesis presents a sensorless speed control drive of Brushless DC motors
used in reciprocating compressors. These compressors cause periodic load torque
variations on the motor, consequently mechanical vibrations ...
Modelling SAG milling power and specific energy consumption including the feed percentage of intermediate size particles
(Elsevier, 2015)
Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual comminution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and secondary ball milling. ...
New approach of induction machine drive using an adaptive digital PID controller with gain planning based on artificial neural networks
(1999-12-01)
The present work introduces a new strategy of induction machines speed adjustment using an adaptive PID (Proportional Integral Derivative) digital controller with gain planning based on the artificial neural networks. This ...
