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, ...

This paper describes OpenOpticalFlow, an open source optical flow program in Matlab for extraction of high-resolution velocity fields from various flow visualization images. This program is a useful ...

When optical materials (molecules or solid-state semiconductors) are embedded in tiny photonic boxes, known as optical microcavities, they form hybrid light-matter states known as polaritons. Most of ...

Engineers at Northwestern University have successfully achieved quantum communication in parallel with classical channels by identifying specific wavelengths with minimal interference from classical ...
