Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...
Complex fluids, such as polymer melts and concentrated suspensions, are foundational materials for industrial products, including high-strength plastics and optical components. The final performance ...
Researchers have developed an optical system that accurately measures the flow of extraordinarily tiny amounts of liquids -- as small as 10 billionths of a liter (nanoliters) per minute. Researchers ...
