In 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]). However, sophisticated and expensive equipments are required for measuring the respiratory parameters ...

COTTON ELONGATION MEASUREMENT USING HIGH VOLUME INSTRUMENTS
Transactions of the ASAE, 1998Fiber elongation is an important physical property of textile fibers. Elongation determinations were initially performed on individual fibers. This is no longer practical. Individual cotton fibers vary considerably in character and the testing of single fibers is very time consuming. Current testing methods use a bundle of fibers.

A next-generation optical surface form inspection instrument for high-volume production applications
SPIE Proceedings, 2012Despite the introduction of phase-shifting interferometers in the 1980's, high volume catalog and camera production lenses are still inspected using qualitative visual fringe inspection methods. This error-prone inspection technique requires the human operator to quickly judge whether the lens “passes” or “fails” based on the appearance of the ...

An earlier study confirmed the influence of cotton fiber length characteristics on the High Volume Instrument™ (HVI) strength measurement and devised a quantitative correction factor to compensate for the effect. The current paper investigated the validity of two important assumptions utilized in the previous study.

Radiography, 2021
The use of fluoroscopy-assisted surgical procedures has been increasing recently. The extensive use of fluoroscopy, combined with the lack of knowledge about radiation risks among operating room (OR) personnel (surgeons, anaesthetists, nurses, and radiographers), may lead to misconceptions.

The derivation and performance of yarn quality prediction models in a program called Cottonspec is reported. Cottonspec incorporates a large database of fiber and yarn data from commercial spinning mills, a series of regression-based models predicting yarn quality from measured cotton fiber quality parameters and yarn specifications and a user ...

This report contains the results of an experimental and analytical evaluation of instruments and techniques designed to prevent an intoxicated driver from operating his automobile. The prototype 'Alcohol Safety Interlock Systems' tested were developed both by private industry and by the Transportation Systems Center and were all drawn from a class of ...

Instrument-quality digital camera that transitioned to low-cost high-volume production
SPIE Proceedings, 2002MOSAD(copyright), Multiplexed OverSample Analog to Digital conversion, is a low power on focal plane analog to digital, A/D, process that places an oversample A/D at each pixel site. Two full custom designs for a visible light staring array were developed with this approach. One design approach uses a silicon photo diode in combination with photo gates

Fiber properties measured by high volume instrument (HVI) and advanced fiber information system (AFIS) are currently being used in Upland cotton (Gossypium hirsutum L.) breeding. It would be interesting to know if it is equally efficient in selection for parameters measured by the two instrumental systems and how are the correlated selection responses ...
