Automated Recognition of Macro Downburst Using Doppler Weather Radar

open access: yesAtmosphere, 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]

open access: yesSongklanakarin 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 ...

Hemodynamic Data Analysis and Site of Measurement in Children and Adolescents

open access: yesArtery 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.

Overfitting Affects the Reliability of Radial Velocity Mass Estimates of the V1298 Tau Planets

open access: yesThe 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 ...

Eulerian–Lagrangian fluid dynamics study on the effects of inlet radial angle on the performance and flow pattern of multi-inlet cyclone separator

open access: yesAlexandria Engineering Journal, 2023
This paper presents a study on the influence of inlet radial angle in a multi-inlet cyclone separator using Eulerian-Lagrangian (EL) fluid dynamics approach. The investigation focuses on the behavior of air and solid particles within the cyclone.

Filtering Solar-Like Oscillations for Exoplanet Detection in Radial Velocity Observations [PDF]

open access: yesAstronomical Journal, 2019
Cool main-sequence, subgiant, and red giant stars all show solar-like oscillations, pulsations that are excited and intrinsically damped by near-surface convection.
