Variational Uncalibrated Photometric Stereo under General Lighting [PDF]
, 2019 Photometric stereo (PS) techniques nowadays remain constrained to an ideal laboratory setup where modeling and calibration of lighting is amenable. To eliminate such restrictions, we propose an efficient principled variational approach to uncalibrated PS

Electrical actuation and shape recovery control of shape-memory polymer nanocomposites
International Journal of Smart and Nano Materials, 2013 Shape-memory polymers (SMPs) are one of the most popular smart materials due to their light weight and high elastic deformation capability. The synergistic effect of carbon nanofiber (CNF) and carbon nanofiber paper (CNFP) on the electro-actuation of SMP
