This article presents the development of a subcutaneous fat tissue thickness measurement based on ultrasound. Currently, the instrument used for measuring the skinfolds thickness is the caliper. However, it is an instrument that requires a long training period in the anatomic measurement technical field. Measurement using ultrasound has been proposed as an alternative noninvasive technique to measure...
The objective of this paper is present the voice evaluation codification using a real-time voice training system, with tactile and visual feedback based on a game, to be used by deaf people for learning of fundamental frequency. The system consist in a microcontrolled signal generator and a Matlabreg language routine. The signal generator is programmed using serial communication to activate a vibrotactile...
The paper presents a computer vision system based on texture segmentation and on a variation of the standard Hough transform, in which the choice of the parameters that determine the straight line that better represents the image is based on the contour conditions of the particular case of weld line detection on fuel storage tanks, aiming to allow their correct detection by the computer vision system...
In this paper it is proposed a method to the measurement of respiratory flow in the forced oscillations technique (FOT) using an ultrasonic anemometer. It is used the transit time method and the phase difference technique with the measurements of the phase angle between the signal at the transmission and at the receiver to detect changes in the transit time due to flow. The ultrasonic anemometer implementation...
