Optical PIV and LDV Comparisons of Internal Flow Investigations in SHF Impeller

International Journal of Rotating Machinery, 2006
The paper presents a comparison between two sets of experimental results in a centrifugal flow pump. The tested impeller is the so-called SHF impeller for which many experimental data have been continuously produced to built databases for CFD code ...

Visual Calibration for Multiview Laser Doppler Speed Sensing

Sensors, 2019
We present a novel calibration method for a multi-view laser Doppler speed sensing (MLDSS) system. In contrast with the traditional method where only the laser geometry is independently calibrated, the proposed method simultaneously optimizes all the ...

Uterine artery Doppler velocimetry with leiomyomas

Archives of Gynecology and Obstetrics, 1998
The study was conducted to establish a correlation between Doppler velocimetry in relation to uterine weight in any phase of the menstrual cycle and symptoms in women who have leiomyomas. Doppler velocimetry was carried out on both uterine arteries in 18 pre-menopausal women and one post-menopausal woman prior to undergoing abdominal hysterectomy at ...

TEDI: the TripleSpec Exoplanet Discovery Instrument

, 2007
The TEDI (TripleSpec - Exoplanet Discovery Instrument) will be the first instrument fielded specifically for finding low-mass stellar companions. The instrument is a near infra-red interferometric spectrometer used as a radial velocimeter.

Role of second trimester uterine artery doppler in early prediction of preeclampsia and intrauterine growth restriction among high-risk Bahamian residents

SAGE Open Medicine
Background: Uterine artery doppler velocimetry has proven to be efficient in the prediction of preeclampsia and intrauterine growth restriction. We aimed to determine its value among high-risk Bahamian women and the most predictive parameter. Methods: We
