Automated Recognition of Macro Downburst Using Doppler Weather Radar
Atmosphere, 2022 In light of the macro downburst’s ground divergent flow field characteristics and high reflectivity, this paper proposes an algorithm for identifying the downburst area using a Doppler weather radar low-level radial velocity and reflectivity factor ...

Hydrodynamic flow between rotating stretchable disks in an orthotropic porous medium [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 A mathematical model of convective steady flow over rotating disks in an orthotropic porous medium has been developed and solved the non-dimentional governing equations for flow by the shooting method that uses fourth order Runge- Kutta integration ...

Research on Tangential Velocity Solution and Accuracy Analysis of Radar Target [PDF]
MATEC Web of Conferences, 2023 In this paper, a calculation method for the tangential velocity solution of radar target based on linear vector method is proposed. It makes full use of the advantage of high precision radial velocity measurement of radar, and realizes the accurate ...

A wide star–black-hole binary system from radial-velocity measurements [PDF]
Nature, 2019 All stellar-mass black holes have hitherto been identified by X-rays emitted from gas that is accreting onto the black hole from a companion star. These systems are all binaries with a black-hole mass that is less than 30 times that of the Sun1–4. Theory

Overfitting Affects the Reliability of Radial Velocity Mass Estimates of the V1298 Tau Planets
The Astronomical Journal, 2023 Mass, radius, and age measurements of young (≲100 Myr) planets have the power to shape our understanding of planet formation. However, young stars tend to be extremely variable in both photometry and radial velocity (RV) measurements, which makes ...

Hemodynamic Data Analysis and Site of Measurement in Children and Adolescents
Artery Research, 2020 Pulse wave velocity is a method of functional vascular evaluation. The gold standard is the carotid-femoral pulse wave velocity measurement. However, the software allows measurement among radial, carotid and femoral artery.

RadVel: The Radial Velocity Modeling Toolkit [PDF]
, 2018 RadVel is an open-source Python package for modeling Keplerian orbits in radial velocity (RV) timeseries. RadVel provides a convenient framework to fit RVs using maximum a posteriori optimization and to compute robust confidence intervals by sampling the
