Download or read book Design and Development of a Novel Device for Tissue Viscoelasticity Measurement written by Ali Sabti and published by . This book was released on 2011 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a novel device for measuring the viscoelastic properties of biological tissue. The ability to measure the mechanical properties of tissue is of special interest for many medical applications; ranging from disease diagnostics to surgical operations and simulations. In practice, physicians use a technique called palpation to detect the presence of viscoelastic property changes which are associated with the healthiness of tissue. Palpation relies exclusively on the expertise and experience of the physician and is only effective if the difference in tissue stiffness is profound. Current technologies for the measurement of tissue healthiness, including ultrasound, have been shown to be incapable of detecting isoechoic lesions even though they were significantly stiffer than surrounding tissue. The new device presents a reliable, accurate and quantitative method for determining the mechanical properties of soft tissue. Consequently, the healthiness of the tissue or the presence of lesions can be found.

Download or read book Development of an Ultrasonic Sensing Technique to Measure Lubricant Viscosity in Engine Journal Bearing In Situ written by Michele Schirru and published by Springer. This book was released on 2017-02-21 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a novel ultrasonic instrument for non-invasive and in-situ characterization of journal bearing lubricant viscosity. In particular, the application to journal bearings is described by non-invasively measuring the viscosity and localized power losses throughout operation. This ultrasonic viscometer is based on the reflection of polarized shear waves from a thin resonating coating layer to increase the measurement sensitivity, in comparison to conventional ultrasonic methods. This instrument allows for a full engine oil viscoelastic characterization in-situ. The book investigates the effects of temperature, pressure and shear rate, and describes in detail the ultrasonic setup and method. Further, it demonstrates that the same technique can be applied similarly to monitor the lubrication of other engine components. As such, it offers a unique instrument that can drive the research of oil formulations to improve engine performance and fulfill the requirements of international fuel economy regulations.

Fenrick and published by Ralston, Alta. : Defence Research Establishment Suffield. This book was released on 1980 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel device for measuring the viscoelastic properties of thickened liquids has been built and tested at DRES. The device involves the withdrawal of a thin metal rod from the liquid under test. The variation in force applied to the rod as the filament of liquid between the rod and the liquid surface relaxes and separates is monitored by strain gauges and displayed on an oscilloscope. The oscilloscope traces provide force time signatures unique to each combination of viscosity and elasticity, which can be photographed and compared. The apparatus and its development are described in detail and oscillographic signatures obtained from various viscoelastic liquids are shown. Some initial theory is discussed and some recommendations are set forth. (Author).

This book was released on 1971 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ultrasonic velocimeter system using two nearly identical velocimeters was developed that could measure the differences in speeds of sound between pure liquids and solutions over the pressure range ambient to 2000 psi and the temperature range ambient to 100C. Accuracy of two parts in 1/one million in frequency corresponding to an average deviation in the speed for sound of 0.3 cm/sec is demonstrated. (Author).
