Feature Tracking Velocimetry Applied to Airborne Measurement Data from Murg Creek

E3S Web of Conferences, 2018
A new image feature tracking velocimetry is presented and tested on airborne video data available from a previous study at Murg Creek (Canton Thurgau, Switzerland). Here, the seeded flow scenery had been recorded by an off-the-shelf action camera mounted

Predictive Value for Preeclampsia of sFlt‐1:PlGF Ratio in Pregnancy Complicated by Gestational Diabetes

Diabetes/Metabolism Research and Reviews, Volume 42, Issue 6, September 2026.
ABSTRACT Background and Aims Gestational diabetes (GDM) and preeclampsia (PE) are major complications of pregnancy. The ratio of soluble Fms‐like tyrosine kinase 1 to placental growth factor (sFlt‐1/PlGF) may predict the short‐term absence of PE in pregnant women with clinically suspected PE. The aim of this study was to determine the role of placental

Optimal velocity estimation model based on non-differential Doppler observations from BDS-3 satellites

Dianxin kexue, 2021
An optimized velocimetric model based on non-differential Doppler observations from BDS-3 satellites with high accuracy and low model complexity was proposed to address insufficient accuracy and low efficiency of velocity estimation method.The ...

Stereo Thermal Marking Velocimetry

Frontiers in Mechanical Engineering, 2018
This paper presents a novel approach to measuring and mapping shape and motion of the water surface. The approach combines and borrows from existing techniques, such as stereo imaging shape recognition and tracking, infrared (IR) laser marking and ...

Comparative value of growth velocity and umbilical artery Doppler for the prediction of adverse perinatal outcomes in growth‐restricted pregnancies

Pregnancy, Volume 2, Issue 5, September 2026.
Abstract Introduction Fetal growth restriction (FGR) is associated with an increased risk of neonatal morbidity and mortality. Current diagnostic criteria for FGR do not discriminate between constitutionally small and pathologically restricted fetuses.

Droplet size spectrum, velocity, angle and flow rate of pulse‐width‐modulated spray nozzles with adjuvants

Pest Management Science, Volume 82, Issue 9, Page 8831-8843, September 2026.
Optimizing PWM performance requires not only appropriate duty cycle selection, but also careful choice of adjuvant formulation tailored to each nozzle type. Drift control agents increased droplet size and reduced fine droplets, mitigating PWM‐induced variability. Decreasing the duty cycle consistently narrowed the spray angle.

Upconversion Photonic Doppler Velocimetry Based on Stimulated Brillouin Scattering

Photonics
Optical up-conversion photonic Doppler velocimetry (PDV) based on stimulated Brillouin Scattering (SBS) with an all-fiber link structure is proposed in this article. Because SBS limits the laser power transmitted by a fiber over long distances, the probe

Home telemonitoring in high‐risk pregnancies: A Finnish retrospective cohort study

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 9, Page 1689-1697, September 2026.
This retrospective study suggests that home telemonitoring may provide an acceptable approach for managing selected high‐risk pregnancies. Safe and effective implementation requires careful patient selection and adherence to evidence‐based clinical protocols.

[Doppler velocimetry].

Archivio italiano di urologia, andrologia : organo ufficiale [di] Societa italiana di ecografia urologica e nefrologica, 1994
After a brief historical introduction, the Authors describe the methodology of the continuous wave basic and dynamic Doppler examination of the penile arteries as well as the main normal and pathologic patterns. Some special tensiometric tests are reported. Advantages and limits of the afore mentioned examinations are discussed.

Development of an Imaging‐Based Method for Analyzing Voided Urine Flow Using Conventional and High‐Speed Video Cameras: A Phantom Study

LUTS: Lower Urinary Tract Symptoms, Volume 18, Issue 5, September 2026.
ABSTRACT Aims This study examined whether voided urine form could be an independent parameter to evaluate pathology of the lower urinary tract separately from conventional uroflowmetric measurements. We also evaluated a novel combined methodology of dynamically measuring the velocity and cross‐sectional area (CA) of voided urine.
