A New Measuring Method for Underwater Displacement Utilizing Sound Signal : Experimental Relationship between Sound Frequency and Displacement

Experimental induction of left abomasal displacement: a new educational technique

The purpose of this study was to induce abomasal displacement to the left, and to let the undergraduate and post graduate students get used to the ping sounds of abomasum and other clinical manifestations. The procedure was carried out on eight young bulls, they were sedated and a 2 m flexible tube was inserted through the nasal canal into the rumen. By laparo-rumenotomy, 20 cm of the tube was ...

A New Method of Linear Displacement Measurement Utilizing Grayscale Image

Several research works exploring the potential of utilizing grayscale image for the measurement of many physical phenomena has been published. In this present paper we have designed a new linear displacement sensor utilizing the grayscale image. This sensor is based on temporal changes in the intensity of light by the movement of grayscale image with the linear displacement of target. The varia...

A displacement-measuring instrument utilizing self-mixing interferometry

We develop a self-mixing laser interferometer for the measurement of displacements on a generic target surface. The measurement is based on the bright-speckle tracking, a technique we have recently proposed to solve amplitude fading associated with the speckle statistics when the displacement to be covered is well in excess of the speckle longitudinal size. We implement the dynamical tracking o...

A Measuring Method for Angular Displacement Based on Correlation Algorithm

The existing angular displacement measurement methods rely on the manufacturing precision of the fixedplate and moving-plate with high manufacturing cost, and it is difficult to overcome a static error and drift for the static measurement method. A kind of angular displacement measuring method based on correlation algorithm is presented with the characteristics of a low manufacturing cost, high...
