Measuring tidal volume and functional residual capacity change in sleeping infants using a volume displacement plethysmograph.
The noninvasive measurement of infant lung function during unsedated sleep in infants has been a long-standing objective in paediatric respiratory medicine. This note reports on the design and performance of a head-out volume-displacement plethysmograph (VDP) that overcomes some of the limitations of traditional lung function apparatus. The VDP comprises a rigid acrylic box with an integral wat...
متن کاملMeasuring Control Delay Using Second-by-second Gps Speed Data
High-resolution vehicle speed profiles obtained from sophisticated devices such as global positioning system (GPS) receivers provide an opportunity to accurately measure intersection delay, composed of deceleration delay, stopped delay, and acceleration delay. Although the delay components can be measured by manually examining the speed profiles or derived timespace diagrams, identifying when v...
متن کاملVIEWPOINT Measuring the Tidal Force on a
A tom interferometers have been used to make highprecision measurements in a diverse array of fields. Their more familiar optical counterparts, light interferometers, use matter elements such as mirrors and beam splitters to manipulate light waves. Atom interferometers invert these roles: laser pulses manipulate matter waves of atoms. These pulses split a matter wave into two, redirect the two ...
متن کاملDetecting andmitigating ocean tidal loading displacements in the Bay of Fundy using GPS
Tidal induced displacement is one of the systematic errors that contribute to the scatter in the geodetic measurements derived from the GPS system. This paper focuses on ascertaining and reducing tidal induced errors due to ocean tide loading (OTL) at two GPS sites, namely CGSJ (Coast Guard Saint John, New Brunswick) and DRHS (Digby High School, Nova Scotia), established under the Princess of A...
متن کاملRelativistic corrections in displacement measuring interferometry
Displacement measuring interferometry is based on measuring the Doppler frequency shift that a beam of radiation undergoes upon reflection off a mirror connected to a moving stage. Usually the velocity of the reflecting stage is very small compared to the speed of light and is therefore deduced using the classical expression for the Doppler shift. We calculate relativistic corrections to the Do...
