We study the problem of distributed velocity alignment among a group of nonholonomic agents in 2 and 3 dimensions. Inspired by social aggregation phenomena such as flocking and schooling in birds and fish, we develop vision based control laws for velocity alignment and motion coordination. The proposed control laws are distributed, in the sense that only information from neighboring agents are ...

A novel class of multi-D-shaped optical fiber suited for refractive index measurements is presented. The multi-D-shaped optical fiber was constructed by forming several D-sections in a multimode optical fiber at localized regions with femtosecond laser pulses. The total number of D-shaped zones fabricated could range from three to seven. Each D-shaped zone covered a sensor volume of 100 μm dept...

   The area of nano-pigments is a limitless field with exceptional potential applications in industry, and their application is becoming the focus of many research groups worldwide in recent years due to their outstanding and tunable properties. Titanium dioxide (TiO2) nanoparticles, on the other hand, are among the most widely used pigment particles, and the interest for utiliza...
