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 ...

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.

PLGA‐particle‐based vaccine induces SARS‐CoV‐2‐specific antibody and T‐cell responses

British Journal of Pharmacology, Volume 183, Issue 13, Page 3619-3632, July 2026.
A novel coronavirus disease 2019 (COVID‐19) vaccine encapsulating recombinant severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spike receptor binding domain (RBD) with the double stranded RNA (dsRNA) analogue Riboxxim induces robust systemic and respiratory T‐ and B‐cell responses in mice.

Investigation by laser doppler velocimetry of the effects of liquid flow rates and feed positions on the flow patterns induced in a stirred tank by an axial-flow impeller [PDF]

, 2002
The (ow patterns established in a continuously-fed stirred tank, equipped with a Mixel TT axial-(ow impeller, have been investigated bylaser Doppler velocimetry, for a high and a low value of mean residence time—mixing time ratio.

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

A Non‐Reciprocal Architected Porous Medium

Advanced Functional Materials, Volume 36, Issue 47, 11 June 2026.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.
