1. 1. The term 'airflow obstruction' is commonly used to describe two different aspects of airways disease: ( a) a rise in airways resistance during ordinary quiet tidal breathing and ( b) a reduction in maximum expiratory flow. In severe air-ways obstruction there is characteristically both...
Measurements on the inverse filtered airflow waveform (the ''glottal waveform'') and of estimated average transglottal pressure and glottal airflow were made from noninvasive recordings of productions of syllable sequences in soft, normal, and loud voice for 25 male and 20 female speakers. Statis...
Considering current world events, the accurate measurement of the dynamic pressure associated with air-blast, as well as its effect on structures, is highly important. Yet, the accurate measurement of this pressure remains one on the biggest challenges that can be presented to the measurement engine...
Lorentz nitrogen-broadening coefficients and nitrogen pressure-induced shift coefficients have been measured for six lines in the ν 1 band and 98 lines in the ν 3 band of H 2 16 O. The results were obtained from analysis of 10 high-resolution (0.01 cm 1 ) infrared absorption spectra recor...
METHODS ARE PRESENTED WHICH ARE USED TO DETERMINE THE AIR PRESSURE ACTING IN EXISTING OPEN CUTS, AND THE COINCIDENT SOIL MOVEMENTS. A HISTORICAL REVIEW IS ... RB Peck - 《Hydraulic Jacks》 被引量: 1发表: 1941年 Research on the Earth Pressure and Internal Force of a High-Fill Open-Cut Tu...
A dew-point meter capable of measuring humidity at high vapour pressure and high temperature has been constructed and tested. Humidity measurements in pure steam were made over the temperature range 100 - 1500957-0233/7/5/003/img1C and a vapour pressure range of 1 - 4 bar. The dew-point...
From the simulation results, the effective dose received by an individual from the indoor air of the workplace was also calculated. Similar content being viewed by others Analysis of the air stream flow parameters generated by the positive pressure ventilator—full scale experiment and CFD simulation...
We propose a lump-sum and turn-to-turn model of an air-core helical inductor constructed from conductive yarns, and systematically analyze and quantify the parasitic elements of conductive yarns. Using three commercial conductive yarns as examples, we compare the frequency response of copper-based ...
The existence of sufficient air content next to the solid boundaries prevents cavitation damage, the region upstream and next to the inception point will be then critical for evaluation of cavitation risk. Velocity and pressure field measurements in the non aerated region of the spillway will be ...
