PIV methodology for small scale measurement [PDF]
EPJ Web of Conferences, 2022 Measurement of velocity fields by PIV method is often limited by the scale of the measured model. This is doubly true for the stereo PIV method. Problems of measurement in small (but still macroscopic) scales are associated with optical distortions in ...

Effect of Directional Movement on Dynamic Light Scattering
IEEE Photonics Journal, 2021 Dynamic light scattering is a standard technique of nano-particle sizing in colloid systems. However, it is difficult to measure the particle size accurately in the flowing dispersion, which is inevitable in many applications, such as on-line measurement.

Galileo, Measurement of the Velocity of Light, and the Reaction Times
Perception, 2009 According to the commonly accepted view, Galileo Galilei devised in 1638 an experiment that seemed able to show that the velocity of light is finite. An analysis of archival material shows that two decades later members of the Florence scientific society Accademia del Cimento followed Galileo guidelines by actually attempting to measure the velocity of
