A portable instrument for the volume measurement of high-frequency percussive ventilators
2010In recent years, the usefulness of High Frequency Percussive Ventilation (HFPV) has been clinically valued as a suitable alternative to conventional mechanical ventilation especially in particularly conditions (for example in pulmonary resection [1]). It acquires the flow with a sampling rate of 2 KHz, computes the volume every 64 samples by numerical ...

The Effect of Gin Machinery on Measurement of High Volume Instrument Color and Trash of Cotton
Transactions of the ASAE, 1994Adoption of the high volume instrument (HVI) classification system for the official marketing criteria for cotton coupled with the separation of color and trash into different grade components requires that ginners and producers be knowledgeable of the impact of gin equipment on color and trash.

The six-volume report presents the technical methodology, data samples, and results of tests conducted on the SOAC on the Rail Transit Test Track at the High Speed Ground Test Center in Pueblo, Colorado during the period April to July 1973. The Test program comprises three areas: Vehicle testing, ways and structures testing and track geometry ...

This study explores the influence of cotton fiber length characteristics on the High Volume Instrument (HVI) strength measurement. A set of cotton samples cut at different lengths from a common parent sliver was used. HVI strength data exhibited a consistent trend as a function of the fiber length properties.

Accurate and regular calibration of measuring instruments plays a vital role in maintaining product quality and the safety of industrial processes. In busy workshops, prioritizing the calibration of instruments is of great importance. This paper presents a simple and practical model named ABCD, which categorizes measuring instruments into four groups ...
