Measurement of Newtonian fluid slip using a torsional ultrasonic oscillator.
The composite torsional ultrasonic oscillator, a versatile experimental system, can be used to investigate slip of a Newtonian fluid at a smooth surface. A rigorous analysis of slip-dependent damping for the oscillator is presented. Initially, the phenomenon of finite surface slip and the slip length are considered for a half space of Newtonian fluid in contact with a smooth, oscillating solid ...
متن کاملUncertainty Measurement for Ultrasonic Sensor Fusion Using Generalized Aggregated Uncertainty Measure 1
In this paper, target differentiation based on pattern of data which are obtained by a set of two ultrasonic sensors is considered. A neural network based target classifier is applied to these data to categorize the data of each sensor. Then the results are fused together by Dempster–Shafer theory (DST) and Dezert–Smarandache theory (DSmT) to make final decision. The Generalized Aggregated Unce...
متن کاملModeling of Ultrasonic Sensor for Range Measurement for Visually Impaired
Electronic Travel aids, which transform visual environmental cues in to another sensory modality, have been proven to help visually impaired people travel with a great degree of psychological comfort and independence Blind or vision-impaired persons are limited in their normal life activities. They are particularly concerned, because of their need to detect and avoid obstacles, as well as to or...
متن کاملUltrasonic Flow Measurement with Integrated Temperature Measurement Compensation
Compensation for ultrasonic flow measurement has increasingly become the trend for applications that call for higher accuracy and tighter repeatability. Temperature is a variable that tends to have a significant impact on performance. Geometric dimension changes due to thermal expansion and contraction, as well as fluid dynamics, are impacted by temperature and thus have an influence on overall...
متن کاملCalibration Method of an Ultrasonic System for Temperature Measurement
System calibration is fundamental to the overall accuracy of the ultrasonic temperature measurement, and it is basically involved in accurately measuring the path length and the system latency of the ultrasonic system. This paper proposes a method of high accuracy system calibration. By estimating the time delay between the transmitted signal and the received signal at several different tempera...
